A practical nurse is reviewing the medication administration record for a client who is 24 hours postoperative following a bowel resection. The client is scheduled to receive oral metoprolol. Current vital signs are: blood pressure 92/58 mm Hg, apical pulse 116 beats/min, and respirations 22 breaths/min. The client's urine output for the last 4 hours was 85 mL. Which action should the practical nurse take first?

Withhold the metoprolol and immediately report the assessment findings to the registered nurse.

Administer the scheduled metoprolol because the client's heart rate is elevated.

Initiate a prescribed as-needed rapid intravenous fluid bolus of normal saline.

Delay the metoprolol and prioritize administering a prescribed oral opioid for incisional pain.

Show answer & explanation

Answer: Withhold the metoprolol and immediately report the assessment findings to the registered nurse.

Answer

The practical nurse should withhold the metoprolol and immediately report the assessment findings to the registered nurse.

The client is exhibiting signs of compensatory shock (hypotension, tachycardia, and oliguria) 24 hours after major abdominal surgery. Metoprolol, a beta-blocker, lowers both blood pressure and heart rate. Administering this medication would eliminate the client's compensatory tachycardia and exacerbate the hypotension. Within the scope of practice, the practical nurse must withhold the unsafe medication and immediately notify the registered nurse of the client's deteriorating condition.

Step-by-Step Solution

Analyze the client's vital signs and clinical data.

Blood pressure is low (92/58 mm Hg), heart rate is high (116 beats/min), and urine output is low (85 mL over 4 hours, which is approximately 21 mL/hr).

To identify any physiological instability or contraindications to the scheduled medication.

Evaluate the scheduled medication against the clinical data.

Metoprolol is a beta-blocker that lowers both heart rate and blood pressure.

Administering a beta-blocker to a hypotensive, hypovolemic client will block their compensatory tachycardia and dangerously worsen the hypotension.

Determine the appropriate nursing action within the practical nurse scope of practice.

The medication must be withheld and the client's unstable condition must be reported to the registered nurse immediately.

Practical nurses must recognize deteriorating conditions, withhold unsafe medications, and escalate care to the registered nurse for advanced assessment.

The practical nurse (PN) is collecting data on a client who is 4 hours postpartum following a vaginal delivery of a large-for-gestational-age newborn. Which assessment findings indicate a complication of physiological adaptation requiring immediate notification of the registered nurse (RN)? Select all that apply.

Select all that apply

A perineal pad completely saturated with blood within 20 minutes.

Resting heart rate increasing from 76 to 114 beats per minute.

Client report of severe, unremitting perineal pressure.

Intermittent, dull uterine cramping while breastfeeding.

An oral temperature of

100.1^\circ\text{F}

(

37.8^\circ\text{C}

A white blood cell (WBC) count of

18,000 / \text{mm}^3

Show answer & explanation

Answer: A perineal pad completely saturated with blood within 20 minutes.; Resting heart rate increasing from 76 to 114 beats per minute.; Client report of severe, unremitting perineal pressure.

Answer

The correct findings requiring immediate notification are rapid pad saturation, a progressively increasing resting heart rate, and severe, unremitting perineal pressure.

The correct selections represent acute, life-threatening complications of postpartum adaptation. A rapidly saturated pad indicates overt hemorrhage. Tachycardia is a subtle, early compensatory mechanism for hypovolemia. Unremitting perineal pressure strongly suggests a concealed hemorrhage (hematoma). All three require emergency intervention to prevent severe hemodynamic instability.

Step-by-Step Solution

Analyze the client's current status and risk factors.

The client is 4 hours postpartum after delivering a large-for-gestational-age infant, placing her at high risk for uterine atony, hemorrhage, and perineal trauma.

Identifying specific clinical risks guides the PN to anticipate potential life-threatening complications.

Evaluate each finding to differentiate between expected physiological adaptation and acute decompensation.

Heavy bleeding, tachycardia, and severe localized pressure indicate active or concealed blood loss. Uterine cramping during feeding, slight temperature elevation, and elevated WBCs are expected normal variants in the immediate postpartum period.

The PN must accurately interpret clinical data to avoid missing early signs of shock or escalating normal findings unnecessarily.

Determine the priority nursing action based on the identified data.

The abnormal findings threaten Airway, Breathing, and Circulation (ABCs) via hypovolemic shock and require immediate escalation to the RN for medical intervention.

Prompt recognition and reporting of clinical deterioration fall squarely within the PN scope of practice for maintaining physiological integrity.

Key Concept

Early recognition of postpartum hemorrhage and hematoma versus expected normal physiological adaptations (afterpains, transient hyperthermia, and leukocytosis).

Question 3Question →

A practical nurse (PN) is providing care for a client who is 12 hours postoperative following a total thyroidectomy. Which of the following actions by the PN demonstrate appropriate risk reduction and clinical prioritization? Select all that apply.

Select all that apply

Ensuring that emergency suction equipment and a tracheostomy tray are immediately accessible at the bedside.

Promptly escalating a reported morning serum calcium level of 7.4 mg/dL (1.85 mmol/L) to the registered nurse.

Assessing the client's voice quality for hoarseness by asking them to speak a few words during routine checks.

Documenting a resting heart rate of 112 beats per minute and a blood pressure of 100/60 mm Hg without immediate notification.

Accepting a directive from the registered nurse to independently administer an intravenous (IV) push dose of calcium gluconate.

Administering a prescribed oral analgesic by visually recognizing the client rather than verifying two distinct identifiers.

Show answer & explanation

Answer: Ensuring that emergency suction equipment and a tracheostomy tray are immediately accessible at the bedside.; Promptly escalating a reported morning serum calcium level of 7.4 mg/dL (1.85 mmol/L) to the registered nurse.; Assessing the client's voice quality for hoarseness by asking them to speak a few words during routine checks.

Answer

The correct actions include ensuring emergency airway equipment is at the bedside, escalating the critically low serum calcium level, and systematically assessing voice quality for laryngeal nerve damage.

Appropriate risk reduction following a thyroidectomy involves proactive preparation for airway emergencies, immediate escalation of abnormal physiological data (like a critical calcium level of 7.4 mg/dL), and targeted assessments for procedure-specific complications such as recurrent laryngeal nerve damage.

Step-by-Step Solution

Analyze the client's postoperative context and associated physiological risks.

The client is 12 hours post-total thyroidectomy. Primary risks include airway compromise (from edema/bleeding), hypocalcemia (from parathyroid gland damage), and laryngeal nerve injury.

Identifying procedure-specific complications dictates the appropriate nursing assessments and escalation priorities.

Evaluate each nursing action against the identified post-thyroidectomy risks.

Keeping airway equipment at the bedside prepares for respiratory emergencies. Escalating a calcium of 7.4 mg/dL addresses critical hypocalcemia. Checking voice quality actively monitors for nerve damage.

Appropriate clinical actions must directly mitigate the primary risks associated with the client's specific surgery.

Evaluate the remaining actions for general safety and scope of practice violations.

Failing to report borderline vitals (HR 112, BP 100/60) ignores early signs of shock. Accepting an IV push assignment violates the PN scope of practice. Skipping two-identifier checks violates medication administration safety protocols.

Comprehensive risk reduction requires adherence to basic safety standards and legal boundaries of practice, regardless of the specific procedure.

Question 4Question →

A practical nurse (PN) is caring for a 78-year-old client who was admitted with a fractured femur and is receiving scheduled doses of oral oxycodone for pain management. During the night shift, the PN finds the client newly agitated, picking at the bedsheets, and unable to recognize family members. The client's vital signs are blood pressure 102/68 mm Hg, heart rate 94 beats/min, respiratory rate 11 breaths/min, and oxygen saturation 89% on room air. The client's family requests the next dose of pain medication to calm the client. Which action should the PN take first?

Withhold the oxycodone, apply supplemental oxygen, and promptly report the findings to the registered nurse (RN).

Administer the prescribed oxycodone to manage the pain that is likely causing the client's severe agitation.

Explain to the family that nighttime confusion is an expected response in older adults and administer the medication.

Accept a verbal order from the on-call provider to administer an intravenous push dose of lorazepam to ensure safety.

Show answer & explanation

Answer: Withhold the oxycodone, apply supplemental oxygen, and promptly report the findings to the registered nurse (RN).

Answer

The correct action is to withhold the oxycodone, apply supplemental oxygen, and promptly report the findings to the registered nurse (RN).

The client is demonstrating signs of significant respiratory depression (11 breaths/min) and resulting hypoxia (89% oxygen saturation), which are life-threatening adverse effects of opioid analgesics like oxycodone. Acute confusion and restlessness in an older adult are frequently the primary, early signs of hypoxia. The safest and most appropriate action within the PN scope of practice is to withhold the respiratory depressant, intervene by applying oxygen to address the immediate breathing compromise, and escalate the critical situation to the RN immediately.

Step-by-Step Solution

Analyze the client's clinical presentation and vital signs.

The client has a low respiratory rate (11 breaths/min), hypoxia (89% oxygen saturation), and acute neurological changes (agitation, confusion).

To identify any immediate life-threatening conditions or contraindications to scheduled medications.

Correlate the assessment findings with the prescribed pharmacological therapy.

The findings represent adverse effects of oxycodone (respiratory depression) and the resulting hypoxia (manifesting as acute confusion).

To determine if the medication is safe to administer or if it is contributing to the client's deterioration.

Determine the priority nursing intervention within the PN scope of practice.

The priority is to withhold the offending medication, support the respiratory system with oxygen, and escalate the findings to the RN.

Airway and breathing are the highest priorities. PNs must recognize critical changes, intervene safely within their scope, and communicate urgently with the supervising RN.

Opioid safety, recognition of hypoxia-induced delirium, and PN scope of practice.

Question 5Question →

While checking on a client who underwent a subtotal thyroidectomy earlier in the shift, the practical nurse observes that the client is unusually restless. The client points to the surgical area and whispers, "It feels really tight in my neck." Which action should the nurse take first?

Evaluate the client's respiratory rate, effort, and oxygen saturation.

Reassure the client that a sore and tight throat is expected from the breathing tube.

Administer the prescribed as-needed analgesic to relieve surgical discomfort.

Lower the head of the bed completely flat to decrease tension on the neck.

Show answer & explanation

Answer: Evaluate the client's respiratory rate, effort, and oxygen saturation.

Answer

The nurse must first evaluate the client's respiratory rate, effort, and oxygen saturation to assess for an airway obstruction.

Following a thyroidectomy, the client is at an elevated risk for airway compromise due to localized swelling, edema, or hemorrhage (hematoma formation). Restlessness is a classic early sign of hypoxia, and the sensation of neck tightness strongly suggests physical airway compression. Applying the ABC (Airway, Breathing, Circulation) framework dictates that the nurse must assess the client's respiratory status and airway patency immediately before initiating any other intervention.

Step-by-Step Solution

Analyze the client's clinical cues.

The client had a recent neck surgery (thyroidectomy) and is showing signs of new restlessness along with a subjective feeling of throat tightness.

Recognizing these cues is essential because the surgical site is directly adjacent to the trachea, making the client highly vulnerable to local swelling or hemorrhage.

Apply the ABC (Airway, Breathing, Circulation) priority framework.

Airway assessment becomes the immediate clinical priority over addressing pain or client positioning.

Restlessness is an early indicator of hypoxia, and a tight throat suggests possible airway compression from a hematoma, requiring urgent respiratory evaluation.

The healthcare team is managing the recovery of a client who underwent a left total knee arthroplasty the previous day. The client is receiving continuous epidural analgesia and requires assistance with daily activities. Which interventions are appropriate for the practical nurse to incorporate into the client's basic care routine? Select all that apply.

Select all that apply

Place a rolled towel or small blanket under the client's left ankle to suspend the heel.

Position a supportive pillow directly beneath the left popliteal space to alleviate joint tension.

Instruct unlicensed assistive personnel (UAP) to perform the client's first out-of-bed transfer to the bedside recliner.

Apply intermittent cold therapy packs to the surgical joint for 20 minutes at a time.

Utilize a fracture pan rather than a standard bedpan when assisting the client with elimination in bed.

Continue routine hygiene care without reporting a borderline blood pressure of 96/58 mm Hg, assuming it is an expected effect of the epidural.

Show answer & explanation

Answer: Place a rolled towel or small blanket under the client's left ankle to suspend the heel.; Apply intermittent cold therapy packs to the surgical joint for 20 minutes at a time.; Utilize a fracture pan rather than a standard bedpan when assisting the client with elimination in bed.

Answer

The correct interventions include suspending the heel with a rolled towel, applying intermittent cold therapy, and utilizing a fracture pan for elimination.

The correct interventions focus on preventing joint contractures by maintaining knee extension through heel suspension, utilizing intermittent cold therapy to manage local edema, and using a fracture pan to minimize painful hip and knee flexion. These actions directly support comfort and physiological integrity without risking joint deformities or compromising safety.

Step-by-Step Solution

Analyze the surgical procedure (total knee arthroplasty) to determine specific positioning requirements.

The knee must be kept in full extension to prevent contractures. Placing anything behind the knee is contraindicated, but suspending the heel is appropriate.

Flexion contractures permanently impair mobility and surgical success.

Evaluate the impact of continuous epidural analgesia on basic care and mobility.

Epidural analgesia affects motor function, sensory perception, and sympathetic tone (blood pressure).

These physiological changes increase the risk for orthostatic hypotension and falls during initial transfers.

Differentiate between tasks appropriate for the LPN versus those requiring RN assessment or those that can be delegated to UAP.

Initial transfers for complex patients cannot be delegated to UAP. Reporting borderline vital signs is a required LPN action.

Operating strictly within the LPN scope of practice ensures client safety.

Select the basic care options that promote comfort, prevent complications, and adhere to safety standards.

Cold therapy, fracture pans, and heel suspension are selected as safe, effective basic care measures.

These interventions directly address the client's postoperative physiological needs.

Elevate the head of the bed to a semi-Fowler's position to promote comfortable lung expansion.

Ensure that a limb alert bracelet is placed on the left arm to restrict venipunctures and blood pressure readings.

Show answer & explanation

Answer: Elevate the client's left arm and hand on a pillow above the level of the heart.; Assist the client with performing prescribed gentle hand and wrist range-of-motion exercises on the left side.; Elevate the head of the bed to a semi-Fowler's position to promote comfortable lung expansion.; Ensure that a limb alert bracelet is placed on the left arm to restrict venipunctures and blood pressure readings.

Answer

The correct interventions are elevating the left arm, assisting with left hand and wrist exercises, elevating the head of the bed to a semi-Fowler's position, and ensuring a limb alert bracelet is on the left arm.

For a client recovering from a modified radical mastectomy with axillary lymph node dissection, basic care and comfort must focus on preventing lymphedema, promoting lymphatic drainage, and ensuring adequate respiratory function. Elevating the affected arm above the level of the heart facilitates fluid return. Maintaining a semi-Fowler's position promotes comfortable lung expansion and drainage. Assisting with early, gentle hand and wrist exercises prevents contractures and promotes circulation. Placing a limb alert on the affected side is essential to prevent injury and lymphedema from venipunctures or blood pressure cuffs.

Step-by-Step Solution

Analyze the client's surgical procedure and associated risks.

The client had a left-sided modified radical mastectomy with axillary lymph node dissection, resulting in a high risk for lymphedema on the left side and a need for specific positioning.

Understanding the anatomical changes determines the correct basic care and comfort measures.

Evaluate the positioning and comfort measures provided in the options.

Elevating the affected arm, elevating the head of the bed, and avoiding the operative side promote fluid drainage and respiratory function. Positioning on the left side is contraindicated.

Correct positioning prevents complications like edema and compromised respiratory status.

Evaluate the safety and physiological stability measures.

The left arm must be protected from trauma (e.g., blood pressure cuffs, needles). Additionally, borderline vital signs like tachycardia and hypotension must be recognized as potential shock, not ignored.

Preventing limb injury and escalating critical vital signs are essential components of safe physiological care.

Key Concept

Postoperative basic care following a mastectomy with lymph node dissection includes preventing lymphedema, protecting the affected limb, promoting respiratory function, and maintaining vigilance for signs of hypovolemic shock.

Question 8Question →

A practical nurse (PN) is providing basic care and comfort for an older adult client who returned to the unit 4 hours ago following a right femoral cardiac catheterization. The client has a history of mild dementia and requires assistance with activities of daily living (ADLs). Which actions should the PN include in the plan of care? (Select all that apply.)

Select all that apply

Assist with feeding while keeping the head of the bed elevated no more than 30 degrees.

Place the client on a fracture bedpan for elimination to minimize movement of the right leg.

Support the right leg with a trochanter roll to maintain proper alignment and promote comfort.

Assist the client to sit on the side of the bed to facilitate a comfortable position for a bed bath.

Delegate the evaluation of the client's right pedal pulse to the unlicensed assistive personnel (UAP) during hygiene care.

Attribute the client's sudden onset of extreme restlessness to their dementia and dim the room lights.

Show answer & explanation

Answer: Assist with feeding while keeping the head of the bed elevated no more than 30 degrees.; Place the client on a fracture bedpan for elimination to minimize movement of the right leg.; Support the right leg with a trochanter roll to maintain proper alignment and promote comfort.

Answer

The correct actions are to assist with feeding while keeping the head of the bed elevated no more than 30 degrees, use a fracture bedpan to minimize leg movement, and support the right leg with a trochanter roll.

Following a femoral cardiac catheterization, the client must remain on bed rest with the affected leg completely straight and the head of the bed elevated no more than 30 degrees to prevent dislodging the clot at the arterial puncture site. Using a fracture bedpan allows for elimination without excessive lifting or bending of the hips. A trochanter roll maintains alignment and prevents external rotation, promoting comfort. Assisting with feeding at a safe, low elevation ensures basic nutritional needs are met without compromising the surgical site.

Step-by-Step Solution

Identify the physiological constraints based on the recent procedure.

The client had a right femoral cardiac catheterization, which requires strict bed rest, the right leg to be kept completely straight, and the head of the bed to be elevated no more than 30 degrees.

Bending the hip increases pressure on the femoral artery puncture site, risking severe hemorrhage.

Evaluate the proposed basic care interventions against the procedural constraints.

Feeding at a 30-degree angle, using a fracture bedpan, and applying a trochanter roll all allow for necessary ADLs while maintaining the required straight-leg and low-elevation position.

Basic care must be adapted to prioritize client safety and prevent procedural complications.

Analyze the clinical presentation and delegation tasks for safety.

Evaluating a pedal pulse is an assessment that cannot be delegated, and sudden restlessness is a critical sign of potential shock, not a baseline dementia symptom.

The PN must practice within their legal scope and prioritize physiological life-threatening changes over routine comfort measures.

Administer the pantoprazole to address the abdominal pain, but withhold the metoprolol due to the low blood pressure.

Administer both medications as prescribed and instruct the client to remain in a supine position to manage the dizziness.

Perform a comprehensive cardiovascular assessment to determine the cause of the vital sign changes before intervening.

Show answer & explanation

Answer: Withhold the scheduled medications and immediately notify the registered nurse (RN) of the client's condition.

Answer

The PN should withhold all scheduled medications and immediately notify the RN of the client's vital signs and symptoms.

The correct action is to withhold the medications and notify the RN. The client's hypotension, marked tachycardia, and dizziness

24\text{ hours}

after a gastrointestinal bleed are classic indicators of active hemorrhage and hypovolemic shock. In this state, administering oral medications is unsafe due to decreased gastrointestinal perfusion and the risk of aspiration. Furthermore, a beta-blocker like metoprolol would suppress the client's compensatory tachycardia and dangerously lower the blood pressure further. The PN's scope of practice dictates the immediate escalation of these critical, unstable findings to the RN.

Step-by-Step Solution

Analyze the client's clinical data.

The client presents with significant hypotension (

86/52\text{ mm Hg}

), marked tachycardia (

118\text{ beats/min}

), and dizziness.

Identifying abnormal assessment findings is the first step in determining safe medication administration.

Interpret the clinical significance of the findings in the context of the client's history.

These findings in a client with a recent gastrointestinal bleed strongly indicate active internal hemorrhage and hypovolemic shock.

Connecting current vital signs to the admitting diagnosis helps identify physiological instability.

Determine the pharmacological implications for the scheduled medications.

Administering metoprolol (a beta-blocker) would suppress the compensatory tachycardia and further lower blood pressure, worsening the shock. Administering any oral medication is contraindicated due to poor perfusion and potential need for emergency procedures.

Administering medications without considering physiological status can cause severe patient harm.

Apply the PN scope of practice to select the priority action.

The PN must withhold the medications and immediately escalate these critical findings to the RN for comprehensive evaluation and emergency intervention.

The PN role requires recognizing unstable conditions and communicating them promptly to the RN or provider.

Show answer & explanation

Answer: Communicate the assessment findings to the supervising registered nurse.

Answer

Communicate the assessment findings to the supervising registered nurse.

The correct answer demonstrates an understanding of early shock recognition. Tachycardia, tachypnea, narrowing pulse pressure, restlessness, and thirst are classic early signs of hypovolemia, particularly dangerous in a client with a femur fracture capable of concealing massive internal bleeding. The practical nurse must immediately escalate these findings to the registered nurse for rapid medical intervention.

Step-by-Step Solution

Analyze the client's current assessment data compared to baseline.

The client has developed tachycardia, tachypnea, hypotension, anxiety, and thirst.

Identifying trends in vital signs is essential for recognizing physiological deterioration.

Correlate the findings with the client's diagnosis and risk factors.

A fractured femur carries a high risk for significant internal bleeding and subsequent hypovolemic shock.

Understanding the clinical context helps interpret the meaning of borderline or changing vital signs.

Determine the most appropriate intervention within the practical nurse's scope of practice.

The priority is to report these critical changes to the registered nurse immediately for advanced assessment and intervention.

Early recognition and rapid escalation of care are critical to prevent severe complications of shock.

dose using the supplied

50\text{ mcg/mL}

concentration

Show answer & explanation

Answer: Evaluating the client's apical pulse for one full minute and confirming two distinct client identifiers before administering the oral metoprolol

Answer

The correct action is to evaluate the client's apical pulse for a full minute and confirm two distinct patient identifiers before administering the oral metoprolol.

Evaluating the client's apical pulse for one full minute and verifying two distinct client identifiers before administering metoprolol demonstrates adherence to the 'rights' of medication administration. Furthermore, checking the pulse is a critical pre-administration parameter for beta-blockers, and administering oral medications is well within the practical nurse's scope of practice.

Step-by-Step Solution

Evaluate the scope of practice regarding intravenous infusions.

Determine that titrating continuous IV heparin is strictly a registered nurse (RN) responsibility.

Practical nurses cannot independently adjust high-alert continuous IV drips.

Analyze the requirements for safe vaccine administration.

Identify that screening for acute fever and allergies is mandatory before giving the influenza vaccine.

Failing to check contraindications compromises client safety and violates medication administration protocols.

Calculate the correct volume for the prescribed digoxin dose.

Convert

0.125\text{ mg}

125\text{ mcg}

. Divide by the concentration of

50\text{ mcg/mL}

to get

2.5\text{ mL}

The option suggesting

0.25\text{ mL}

is mathematically incorrect and would result in significant underdosing.

Evaluate the safety checks for oral metoprolol.

Confirm that checking the apical pulse and using two client identifiers is correct.

Beta-blockers affect heart rate, and patient identification is a universal medication safety right within the PN scope.

Question 12Question →

A practical nurse (PN) is reviewing the care requirements for a group of assigned clients at the beginning of a shift. Which of the following planned actions demonstrate appropriate application of risk reduction principles within the PN scope of practice? Select all that apply.

Select all that apply

Pausing a continuous enteral tube feeding before placing a client in a supine position for a linen change.

Accepting primary care responsibility for a newly admitted client who requires initiation and titration of a continuous intravenous heparin infusion.

Administering a scheduled oral dose of potassium chloride to a client whose morning serum potassium level is reported as 6.1 mEq/L.

Checking a client's most recent capillary blood glucose level prior to administering a scheduled dose of rapid-acting insulin.

Verifying a client's identity solely by checking the room number and bed assignment before administering a routine daily medication.

Documenting a subtle decrease in urine output and a heart rate increase from 82 to 108 beats/min as expected findings in a client with an active gastrointestinal bleed.

Show answer & explanation

Answer: Pausing a continuous enteral tube feeding before placing a client in a supine position for a linen change.; Checking a client's most recent capillary blood glucose level prior to administering a scheduled dose of rapid-acting insulin.

Answer

The appropriate actions that demonstrate risk reduction within the PN scope are pausing a continuous enteral tube feeding before placing a client supine, and checking a client's capillary blood glucose level prior to administering rapid-acting insulin.

Risk reduction is successfully achieved when the practical nurse adheres to safety protocols and practices within their defined scope. Pausing enteral feedings before laying a client flat prevents regurgitation and aspiration pneumonia. Checking a blood glucose level before administering rapid-acting insulin is a critical safeguard required to prevent iatrogenic hypoglycemia.

Step-by-Step Solution

Evaluate the risk of aspiration associated with continuous enteral feedings.

Pausing the feeding before laying the client flat is identified as a necessary action to prevent aspiration.

Maintaining the head of the bed elevated during and immediately after feedings uses gravity to keep stomach contents from refluxing.

Assess the PN scope of practice regarding intravenous therapy and patient assignments.

Accepting an assignment for a client requiring titration of continuous IV heparin is identified as an action outside the PN scope.

Titrating high-risk IV medications based on laboratory values requires the comprehensive assessment skills of a registered nurse.

Analyze laboratory values in relation to scheduled medications.

Administering additional potassium to a client with a serum level of 6.1 mEq/L is identified as unsafe.

A potassium level above 5.0 mEq/L is elevated; administering more potassium could cause fatal cardiac dysrhythmias.

Review the protocol for safe administration of high-alert medications like insulin.

Checking the blood glucose level prior to insulin administration is identified as a safe, required practice.

Insulin lowers blood sugar; administering it without knowing the current level risks inducing severe hypoglycemia.

Identify the standard requirements for safe client identification.

Using a room and bed number is identified as an unsafe client identification method.

Two unique, client-specific identifiers (such as name and date of birth) must be used to prevent medication errors.

Evaluate the clinical significance of vital sign trends in a client at risk for hemorrhage.

Dismissing tachycardia and decreased urine output in a bleeding client is identified as a dangerous failure to rescue.

These findings represent early compensatory mechanisms for hypovolemic shock and require immediate escalation rather than routine documentation.

Key Concept

Risk reduction involves practicing strictly within the established scope of practice, properly identifying clients using two unique identifiers, escalating critical laboratory and vital sign abnormalities, and performing procedural safeguards such as verifying blood glucose before insulin and preventing aspiration during enteral feeding.

Question 13Question →

A practical nurse (PN) is preparing to administer a prescribed intramuscular medication that is supplied in a single-dose glass ampule. Arrange the following preparation steps in the correct chronological order to ensure safe medication handling and administration.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with clearing the upper stem of medication, followed by protecting the hands with gauze, snapping the ampule away from the body, attaching a filter needle, withdrawing the medication, and finally replacing the filter needle with an appropriate injection needle.

Safe medication preparation from a glass ampule requires a specific sequence to protect both the nurse and the client. The nurse must first ensure all medication is in the lower chamber (flicking the stem) to prevent dose loss. Next, the nurse protects themselves by wrapping the neck and breaking the glass away from their body. Because breaking the glass can introduce microscopic shards into the liquid, the nurse must attach a filter needle to draw up the medication safely. Once the medication is withdrawn without contaminating the needle on the rim, the filter needle must be discarded and replaced with an injection-appropriate needle, as filter needles are not meant for client administration.

Step-by-Step Solution

Flick the upper stem of the ampule lightly to ensure all medication moves into the lower chamber.

All medication is contained within the base of the ampule.

Prevents loss of the prescribed dose when the ampule is opened.

Wrap a sterile gauze pad or an unopened alcohol swab around the narrow neck of the ampule.

A protective barrier is established around the break point.

Protects the nurse's fingers from glass cuts.

Snap the ampule neck quickly and firmly in a direction pointing away from the body.

The ampule is opened safely.

Directs potential glass shards away from the nurse's face and body.

Attach a filter needle to the sterile syringe.

The syringe is equipped to filter out particulate matter.

A resting heart rate of 114 beats/min and a blood pressure of 96/58 mm Hg

New-onset restlessness and the client stating they are waiting for a train

A respiratory rate of 26 breaths/min with shallow chest expansion

The client reports a pain level of 4 on a 0 to 10 scale localized to the suprapubic area

The client's most recent void yielded 150 mL of cloudy, foul-smelling urine

The client's spouse reports the client has experienced gradual forgetfulness over the past two years

Show answer & explanation

Answer: A resting heart rate of 114 beats/min and a blood pressure of 96/58 mm Hg; New-onset restlessness and the client stating they are waiting for a train; A respiratory rate of 26 breaths/min with shallow chest expansion

Answer

The correct findings are a resting heart rate of 114 beats/min with a blood pressure of 96/58 mm Hg, new-onset restlessness with confusion, and a respiratory rate of 26 breaths/min.

The correct options indicate acute systemic deterioration (sepsis), prioritizing Airway, Breathing, and Circulation (ABC) issues. Tachycardia with borderline hypotension suggests early shock. Tachypnea is a primary respiratory compensatory mechanism during systemic stress. Furthermore, older adults frequently exhibit acute confusion (delirium) as a primary sign of hypoxia or worsening infection.

Step-by-Step Solution

Analyze the client's current diagnosis and primary risk factors.

The older adult client has a severe urinary tract infection, placing them at high risk for the infection spreading systemically (sepsis).

Identifying the primary risk helps distinguish expected localized symptoms from emergent systemic complications.

Evaluate vital signs for Airway, Breathing, and Circulation (ABC) compromise.

A heart rate of 114 beats/min with borderline hypotension (96/58 mm Hg) and a respiratory rate of 26 breaths/min indicate physiological stress.

ABCs are the highest priority in acute care, and these borderline vital signs are classic early indicators of shock and respiratory decompensation.

Assess for acute neurological changes compared to baseline.

New-onset restlessness and confusion (delirium) are critical acute findings, distinguishing them from the chronic gradual forgetfulness reported by the spouse.

In older adults, acute mental status changes are often the first sign of hypoxia or systemic infection.

Compare emergent findings with expected localized symptoms.

Mild suprapubic pain and cloudy urine are localized, expected findings that do not require immediate emergency escalation.

Prioritization requires the nurse to address systemic physiological instability before expected, chronic, or local symptoms.

A client is 12 hours postoperative following a total thyroidectomy. While inflating the blood pressure cuff to measure the client's vital signs, the practical nurse observes that the client's hand and fingers suddenly curl inward in a spasm. Which action should the nurse take first?

Notify the registered nurse immediately to report the observation.

Massage the client's hand and fingers to relieve the muscle cramping.

Prepare to administer a prescribed dose of intravenous calcium gluconate.

Evaluate the client's most recent serum potassium level to determine the cause.

Show answer & explanation

Answer: Notify the registered nurse immediately to report the observation.

Answer

Notify the registered nurse immediately to report the observation.

The correct answer is to notify the registered nurse immediately. The client is exhibiting Trousseau's sign, which is an early clinical indication of hypocalcemia (low serum calcium). Because the parathyroid glands are located on the posterior surface of the thyroid, they can be inadvertently damaged or removed during a thyroidectomy. Hypocalcemia can quickly escalate to severe tetany and laryngospasm, which compromises the client's airway. Immediate escalation is required for patient safety.

Step-by-Step Solution

Identify the clinical sign presented in the scenario.

The hand spasm that occurs during blood pressure cuff inflation is known as Trousseau's sign.

Recognizing classic clinical signs is essential for identifying underlying physiological imbalances.

Correlate the clinical sign with the client's surgical history.

The client had a total thyroidectomy. Trousseau's sign indicates hypocalcemia.

The parathyroid glands, which regulate calcium levels, are located adjacent to the thyroid and can be accidentally damaged or removed during a thyroidectomy.

Determine the priority nursing action based on the practical nurse's scope of practice.

The practical nurse must immediately notify the registered nurse.

Hypocalcemia can rapidly progress to severe tetany and life-threatening laryngospasm (airway compromise), requiring immediate RN assessment and collaborative medical intervention.

Question 16Question →

A practical nurse is assigned to care for an older adult client who has oropharyngeal dysphagia following a cerebrovascular accident (CVA). The client is alert and ready for their afternoon meal. Arrange the following nursing actions in the correct chronological order to safely assist the client with eating and prevent aspiration.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence ensures airway safety by first positioning the client upright, preparing the oral cavity, placing food on the strong side, using the chin-tuck maneuver during the active swallow, and finally checking for retained food.

Safe feeding for a client with dysphagia is a systematic process. Environmental and postural safety must be established first by positioning the client at 90 degrees. The oral cavity is then prepared via hygiene. During the actual feeding, food must be placed where the client has motor control (the unaffected side), and the airway must be actively protected during the swallow using the chin-tuck technique. Finally, a post-swallow assessment ensures no residual hazards remain by checking for pocketing.

Step-by-Step Solution

Elevate the head of the bed to 90 degrees.

The client is placed in a high Fowler's position.

An upright posture enlists gravity to direct the food bolus into the esophagus and reduces the physical risk of tracheal entry.

Provide gentle oral hygiene.

The oral mucosa is moistened and sensory receptors are stimulated.

Moistening the mouth facilitates bolus formation and triggers the swallow reflex more effectively.

Place food on the unaffected side of the mouth.

Food is situated where the client has optimal muscle control.

The strong side has intact musculature to safely manipulate and propel the food backward.

Instruct the client to tuck their chin during the swallow.

The laryngeal opening is physically narrowed.

This specific postural adjustment physically protects the airway while simultaneously widening the esophageal opening.

Inspect the buccal cavities for pocketing.

The mouth is confirmed clear of residual food.

Clients with a CVA may unknowingly retain food in the affected cheek, which could be aspirated later when they lie flat or take a breath.

Question 17Question →

A client is admitted to the nursing unit directly after undergoing a percutaneous liver biopsy. To reduce the risk of internal bleeding and ensure safety, what is the most appropriate position for the practical nurse to place this client?

Resting on the right side with a small towel roll under the puncture site

Resting on the left side with a supportive pillow placed behind the back

Lying flat on the back with the lower extremities elevated on pillows

Sitting upright in bed at a 60-degree angle with the knees slightly bent

Show answer & explanation

Answer: Resting on the right side with a small towel roll under the puncture site

Answer

Resting on the right side with a small towel roll under the puncture site

Positioning the client on the right side (where the liver is located) applies direct, continuous pressure to the liver capsule and the biopsy puncture site. This use of body weight, often augmented by a rolled towel, acts as a tamponade to promote hemostasis and minimize the risk of severe internal hemorrhage.

Step-by-Step Solution

Analyze the client's recent diagnostic procedure.

The client had a percutaneous liver biopsy, which involves puncturing a highly vascular organ.

Understanding the nature of the procedure highlights the primary complication to prevent, which is severe bleeding.

Identify the goal of immediate post-procedure positioning.

The primary goal is to apply direct, continuous pressure to the puncture site to promote clotting (hemostasis).

External pressure acts as a mechanical barrier against bleeding from the internal wound.

Determine the optimal anatomical position to achieve this goal.

Placing the client on the right side compresses the liver against the chest wall. Adding a towel roll directly under the right costal margin maximizes this pressure.

The liver is located on the right side of the abdomen; therefore, right lateral positioning uses the client's own body weight to tamponade the bleeding.

Question 18Question →

A client is transferred back to the medical-surgical unit after undergoing a percutaneous liver biopsy. To promote hemostasis and prevent complications, which of the following positions is most appropriate for this client?

Right side-lying position with a folded towel under the puncture site

Left side-lying position with the right knee drawn up toward the chest

Semi-Fowler's position with the head of the bed elevated 45 degrees

Supine position with the lower extremities elevated on pillows

Show answer & explanation

Answer: Right side-lying position with a folded towel under the puncture site

Answer

Right side-lying position with a folded towel under the puncture site

The liver is a highly vascular organ located in the right upper quadrant of the abdomen, making bleeding the most significant risk following a biopsy. Positioning the client on their right side (often with a small towel or pillow tucked under the puncture site) utilizes the client's own body weight to apply continuous, direct pressure to the liver capsule. This splinting action is a fundamental care intervention that promotes hemostasis and prevents severe internal hemorrhage.

Step-by-Step Solution

Identify the anatomical location of the procedure.

The liver is located in the right upper quadrant of the abdomen.

Knowing the organ's precise location dictates where external pressure must be applied.

Determine the primary physiological risk following the procedure.

Because the liver is a highly vascular organ, hemorrhage is the most significant immediate complication after a biopsy.

Identifying the primary risk guides the nurse in selecting the most critical basic care intervention.

Select the position that best mitigates the identified risk.

The right side-lying position is chosen.

This position uses the client's body weight against the mattress (often enhanced by a folded towel) to compress the liver, promoting clot formation and hemostasis.

Show answer & explanation

Answer: Withhold scheduled subcutaneous enoxaparin for a client with a morning platelet count of $75,000\text{/mm}^3$ and notify the registered nurse.; Reinforce teaching for a client starting oral rifampin that their urine, sweat, and tears may turn a harmless red-orange color.; Administer a prescribed oral potassium chloride supplement to a client with a morning serum potassium level of $3.2\text{ mEq/L}$ .

Answer

The correct actions are withholding enoxaparin for thrombocytopenia, reinforcing teaching about expected side effects of rifampin, and administering potassium chloride for hypokalemia.

Safe pharmacological practice for the practical nurse involves withholding enoxaparin when the platelet count is critically low to prevent hemorrhage, educating clients on harmless but startling medication side effects (like rifampin causing red-orange secretions), and appropriately treating documented electrolyte deficits (such as administering potassium for hypokalemia).

Step-by-Step Solution

Evaluate the clinical data and prescribed medication for each client scenario.

Identify therapeutic indications, potential contraindications, and required monitoring for the specific drug classes (anticoagulants, antimicrobials, electrolytes, beta-blockers, opioids).

To ensure clinical safety and prevent adverse pharmacological events.

Analyze each proposed nursing action against the established LPN/PN scope of practice.

Differentiate between tasks that are safe to perform (administering oral/subcutaneous medications, reinforcing teaching) and tasks that must be refused or escalated (IV push medications, ignoring critical safety parameters).

To maintain legal practice boundaries and ensure the highest level of client safety.

Key Concept

The practical nurse must integrate pharmacological knowledge with strict adherence to scope of practice, ensuring safe medication administration, accurate monitoring of laboratory values, and appropriate client teaching reinforcement.

Question 20Question →

A practical nurse is preparing to administer an oral suspension to a client who weighs $154\text{ lb}$ . The healthcare provider has prescribed $15\text{ mg/kg/day}$ to be administered in two equally divided doses. The pharmacy dispenses the medication with a concentration of $0.25\text{ g/5 mL}$ . How many $\text{mL}$ should the practical nurse administer for each dose? Record your answer to the nearest tenth. Do not include units in your answer.

Show answer & explanation

Answer: 10.5

Answer

10.5

To arrive at the correct answer of

10.5

, the practical nurse must systematically process multiple conversions. First, the client's weight is converted to kilograms (

154 \div 2.2 = 70\text{ kg}

). Next, the total daily dose is calculated (

70 \times 15 = 1050\text{ mg/day}

). Because the medication is divided into two equal doses, the single dose requirement is

525\text{ mg}

. Before calculating the volume, the dispensed concentration of

0.25\text{ g/5 mL}

must be converted to milligrams (

0.25 \times 1000 = 250\text{ mg/5 mL}

). Finally, using the desired over have formula:

(525\text{ mg} \div 250\text{ mg}) \times 5\text{ mL}

equals exactly

10.5\text{ mL}

Step-by-Step Solution

Convert the client's weight from pounds to kilograms.

154\text{ lb} \div 2.2\text{ lb/kg} = 70\text{ kg}

Weight-based dosing requires the client's weight in kilograms.

Calculate the total daily dose in milligrams.

70\text{ kg} \times 15\text{ mg/kg/day} = 1050\text{ mg/day}

This establishes the total amount of medication the client needs over a 24-hour period.

Determine the amount required for a single dose.

1050\text{ mg/day} \div 2\text{ doses} = 525\text{ mg/dose}

The prescription specifies two equally divided doses per day.

Convert the supplied medication concentration from grams to milligrams.

0.25\text{ g} \times 1000\text{ mg/g} = 250\text{ mg}

. The available concentration is

250\text{ mg}

per

5\text{ mL}

Units of measurement must match between the desired dose (mg) and the available medication supply (g) before calculating volume.

Calculate the volume to administer for a single dose.

(525\text{ mg} \div 250\text{ mg}) \times 5\text{ mL} = 2.1 \times 5\text{ mL} = 10.5\text{ mL}

Applying the standard dimensional analysis or 'Desired over Have times Volume' formula yields the exact volume to administer.
