A practical nurse (PN) is preparing to administer a prescribed oral liquid suspension of ibuprofen to an 18-month-old toddler. Which action should the PN take to ensure safe medication administration?

Show answer & explanation

Answer: Administer the liquid medication using a calibrated oral syringe directed toward the side of the client's cheek.

Answer

The practical nurse should measure the dose using a calibrated oral syringe and administer it by directing the liquid toward the side of the toddler's cheek.
Administering oral liquids to a toddler using a calibrated oral syringe directed toward the buccal pouch (the side of the cheek) is the safest and most effective method. This approach ensures precise measurement of the medication and significantly reduces the risk of aspiration by preventing the fluid from forcefully hitting the back of the throat.

Step-by-Step Solution

1
Determine the safest and most accurate method to measure an oral liquid medication for a pediatric client.
A calibrated oral syringe must be selected rather than household utensils.
Household spoons lack standardized volumes, creating a high risk for dosage errors in small children.
2
Identify the safest anatomical technique to administer the liquid to a toddler to prevent choking.
The medication should be deposited slowly into the buccal pouch (the side of the cheek).
Directing the fluid away from the back of the throat allows the child time to swallow normally and minimizes the risk of aspiration.

Question 282Question →

A practical nurse is caring for a client who is 48 hours postoperative following a right above-the-knee amputation. To prevent a common musculoskeletal complication associated with this procedure, which positioning action should the practical nurse implement?

Show answer & explanation

Answer: Assist the client into a prone position for 20 to 30 minutes every 3 to 4 hours.

Answer

The practical nurse should assist the client into a prone position for 20 to 30 minutes every 3 to 4 hours.
Prone positioning (lying flat on the stomach) fully extends the hip joint. Following an above-the-knee amputation, clients are at a high risk for developing hip flexion contractures due to the natural tendency to sit or keep the leg elevated for comfort. Placing the client in a prone position for 20 to 30 minutes several times a day actively counteracts this flexion, stretches the flexor muscles, and helps prevent contractures. This intervention is essential for ensuring the client can successfully be fitted for and use a prosthesis in the future.

Step-by-Step Solution

1
Analyze the client's postoperative timeframe and surgical procedure.
The client is 48 hours postoperative following an above-the-knee amputation (AKA).
The postoperative timeframe dictates which positioning interventions are safe and which are contraindicated.
2
Identify the primary musculoskeletal complication associated with this specific surgery.
Hip flexion contractures are a major risk for clients with an AKA.
Understanding the potential complication is necessary to select the correct preventative care measure.
3
Evaluate the physiological impact of each positioning option on the hip joint.
Elevating the limb, sitting in a chair, and a high-Fowler's position all promote hip flexion. Prone positioning promotes hip extension.
To prevent a flexion contracture, the joint must be actively extended to stretch the muscles.
4
Select the positioning action that safely counteracts prolonged hip flexion.
Assisting the client into a prone position for 20 to 30 minutes every 3 to 4 hours is the correct intervention.
This fully extends the hip flexor muscles, preventing shortening and contractures, which is critical for future prosthetic use.

Key Concept

Prevention of hip flexion contractures following an above-the-knee amputation requires avoiding prolonged hip flexion and implementing regular prone positioning to fully extend the joint.
Question 283Question →

During the admission of a client with newly diagnosed disseminated herpes zoster, the nursing team must establish appropriate isolation precautions. Which specific actions should be included in this client's care plan? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Initiate placement in a private room with negative-pressure airflow.; Don a fit-tested N95 respirator, isolation gown, and clean gloves before room entry.; Place a standard surgical mask on the client if transport to another department is essential.; Dedicate reusable medical equipment, such as a stethoscope, to remain inside the client's room.

Answer

The correct interventions for a client with disseminated herpes zoster include initiating placement in a negative-pressure room, donning an N95 respirator, gown, and gloves before entry, placing a standard surgical mask on the client during transport, and dedicating reusable equipment to the room.
Disseminated herpes zoster necessitates both Airborne and Contact precautions. This requires a negative-pressure private room to contain airborne particles. Staff must wear a fit-tested N95 respirator, an isolation gown, and gloves for all interactions. To prevent cross-contamination, reusable room equipment should be dedicated to the client. If transport outside the room is essential, placing a standard surgical mask on the client provides necessary source control.

Step-by-Step Solution

1
Identify the transmission routes for the diagnosed pathogen.
Disseminated herpes zoster requires both Airborne and Contact precautions.
The varicella-zoster virus in a disseminated state is spread through both airborne respiratory particles and direct contact with the vesicular lesions.
2
Determine appropriate room assignment and environmental controls.
A private room with negative-pressure airflow is necessary.
Negative pressure ensures that airborne droplet nuclei do not escape into the general hallway when the door is opened.
3
Select appropriate personal protective equipment (PPE) for healthcare workers.
An N95 respirator, isolation gown, and clean gloves must be donned prior to entry.
The N95 filters airborne particles, while the gown and gloves prevent transmission via direct contact with infectious material.
4
Evaluate protocols for client transport and equipment usage.
The client must wear a surgical mask during essential transport, and medical equipment must be dedicated to the room.
Source control during transport minimizes environmental exposure, and dedicated equipment breaks the chain of contact transmission.

Question 284Question →

Following a shift handoff report, you are reviewing the clinical data of a client who underwent an open splenectomy 12 hours ago. Which of the following findings requires the most urgent notification of the registered nurse (RN)?

Show answer & explanation

Answer: A heart rate of 114 beats per minute with a blood pressure of 98/62 mm Hg

Answer

The correct answer is the finding of a heart rate of 114 beats per minute with a blood pressure of 98/62 mm Hg.
The correct answer identifies vital signs indicative of early hypovolemic shock. The spleen is a highly vascular organ, and hemorrhage is a major, life-threatening complication following a splenectomy. A steadily increasing heart rate (tachycardia) paired with borderline or decreasing blood pressure (hypotension) are classic early compensatory signs of bleeding. The practical nurse must prioritize these circulation indicators (ABCs) and immediately escalate this finding to the registered nurse for prompt intervention.

Step-by-Step Solution

1
Analyze the client's surgical history
The client had an open splenectomy 12 hours ago.
The spleen is a highly vascular organ, making postoperative hemorrhage a primary and life-threatening risk.
2
Evaluate the significance of the vital signs provided in the correct option
A heart rate of 114 bpm (tachycardia) and a blood pressure of 98/62 mm Hg (borderline hypotension) are identified.
These are classic compensatory signs of early hypovolemic shock resulting from internal bleeding.
3
Compare the correct finding against the distractors
The WBC count, temperature, and pain level are determined to be expected or non-emergent findings for a client 12 hours post-surgery.
Expected postoperative physiological responses do not take priority over airway, breathing, or circulation (ABC) compromise.
4
Determine the appropriate nursing action based on the LPN/LVN scope of practice
The finding of potential shock must be escalated to the RN immediately.
The RN must perform a comprehensive assessment and coordinate urgent medical interventions to stabilize the client.

Key Concept

Recognizing and prioritizing early signs of hypovolemic shock (tachycardia, hypotension) in a postoperative client to reduce the risk of severe complications.
Question 285Question →

A 72-year-old client is admitted to the medical unit with acute gastroenteritis and frequent watery stools. During the afternoon shift, the practical nurse (PN) observes that the client is restless, has dry oral mucosa, and exhibits new mild confusion. The client's current vital signs are: blood pressure 102/64 mm Hg (admission baseline 130/80 mm Hg) and heart rate 114 beats/min (admission baseline 84 beats/min). Which action should the PN take first?

Show answer & explanation

Answer: Report the altered mental status and vital sign trends to the registered nurse (RN) immediately.

Answer

The correct action is to report the altered mental status and vital sign trends to the registered nurse (RN) immediately.
The correct action is to immediately escalate the findings to the RN. The client's history of fluid loss, combined with tachycardia, a significant drop in blood pressure from baseline, and new-onset confusion, strongly suggests early hypovolemic shock. The confusion is a critical indicator of inadequate cerebral perfusion, requiring emergent medical intervention beyond routine PN data collection.

Step-by-Step Solution

1
Analyze the client's presenting signs and symptoms.
The client has ongoing fluid loss, new-onset confusion, tachycardia, and a narrowing pulse pressure with hypotension compared to baseline.
Identifying abnormal cues is the first step in clinical judgment.
2
Connect the clinical findings to a physiological process.
The combination of these findings indicates severe dehydration progressing to early hypovolemic shock, leading to poor brain perfusion (causing confusion).
Understanding the pathophysiology of fluid volume deficit allows the nurse to determine the urgency of the situation.
3
Determine the priority nursing action based on the PN scope of practice.
Because the client is demonstrating acute physiological instability, the priority is to notify the RN to initiate rapid medical interventions (such as IV fluid resuscitation).
The PN must recognize life-threatening changes and escalate care to ensure the client receives immediate, appropriate interventions.

A practical nurse (PN) is evaluating a 79-year-old client admitted yesterday with an acute exacerbation of peptic ulcer disease. The client's spouse calls the PN to the room, stating the client suddenly seems highly disoriented and is attempting to get out of bed. The PN observes the client's skin is pale and cool to the touch. Current vital signs are: heart rate 108 beats/minute, respirations 22 breaths/minute, and blood pressure 104/66 mm Hg. The client's admission blood pressure was 142/84 mm Hg. Which action should the PN take FIRST?

Show answer & explanation

Answer: Immediately report the clinical findings and vital signs to the registered nurse.

Answer

The correct action is to immediately report the clinical findings and vital signs to the registered nurse.
The correct action prioritizes the immediate escalation of critical, life-threatening data. The client is exhibiting classic signs of early hypovolemic shock secondary to a suspected gastrointestinal bleed. The significant decrease in blood pressure from baseline, combined with tachycardia, pale/cool skin, and acute confusion (due to decreased cerebral perfusion), requires rapid intervention beyond the PN's independent scope of practice. The RN must be notified immediately to initiate collaborative emergency protocols.

Step-by-Step Solution

1
Analyze the client's current assessment data.
The client has new-onset confusion, pale/cool skin, mild tachycardia (108 bpm), and a significant drop in blood pressure compared to baseline.
Identifying acute changes from baseline is the first step in clinical judgment.
2
Relate the findings to the client's diagnosis.
The client has peptic ulcer disease, placing them at high risk for acute gastrointestinal hemorrhage.
Connecting the history to the current presentation helps determine the underlying cause.
3
Synthesize the physiological cues.
The combination of subtle vital sign changes and altered mental status points to early hypovolemic (hemorrhagic) shock and decreased cerebral perfusion.
Recognizing shock early is critical for patient survival before irreversible damage occurs.
4
Determine the priority PN action.
The PN must immediately escalate the findings to the RN.
Hypovolemic shock is a medical emergency requiring rapid interventions (e.g., fluid resuscitation, blood transfusion) that require RN and provider collaboration.

Question 287Question →

A practical nurse is providing care for a geriatric client on a medical unit. The client, who was previously oriented and cooperative, abruptly begins thrashing in bed, exhibiting rapid breathing, and attempting to climb over the side rails. Which intervention is the priority for the nurse to ensure client safety?

Show answer & explanation

Answer: Check the client's oxygen saturation and vital signs while immediately notifying the registered nurse (RN).

Answer

The priority action is to check the client's oxygen saturation and vital signs while immediately notifying the registered nurse (RN).
The sudden onset of confusion, restlessness, and rapid breathing (tachypnea) in a geriatric client is a hallmark sign of an acute physiological compromise, such as hypoxia. The practical nurse's priority to prevent injury is to quickly gather objective data (vital signs) and escalate the unstable client's condition to the registered nurse (RN) for rapid medical intervention. Addressing the underlying physiological cause is the most effective and safest way to resolve the agitation.

Step-by-Step Solution

1
Analyze the client's sudden change in behavior and respiratory status.
The abrupt onset of confusion, thrashing, and rapid breathing points to an acute physiological problem (such as hypoxia or infection) rather than a simple behavioral issue.
Identifying the root cause of sudden behavioral changes is essential for applying the correct safety and medical interventions.
2
Determine the appropriate nursing intervention and scope of practice.
The practical nurse must collect immediate objective data (vital signs) and escalate this critical change to the registered nurse (RN).
Acute instability requires rapid collaboration between the practical nurse, registered nurse, and provider to resolve the life-threatening cause of the agitation.
3
Evaluate the distractors against established safety protocols.
Applying restraints bypasses less restrictive alternatives. Delegating assessment to a UAP violates scope of practice. Normalizing the symptoms dangerously ignores an acute crisis.
Client safety is best maintained by addressing the physiological threat, not by treating the symptom with unsafe shortcuts.

Question 288Question →

Following a motor vehicle collision, a client with a confirmed pelvic fracture is admitted to the progressive care unit. During the morning assessment, the practical nurse reviews the client's laboratory results, which reveal a hemoglobin level of 9.2 g/dL (92 g/L). The nurse notes that the client has produced only 80 mL of urine over the previous 4 hours. Current vital signs include a heart rate of 118 beats/minute, blood pressure of 102/64 mm Hg, and respiratory rate of 22 breaths/minute. The client suddenly reports an intense, new sensation of pressure in the pelvic region. Which of the following actions should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse immediately about the clinical findings and the client's reported symptoms.

Answer

Notify the registered nurse immediately about the clinical findings and the client's reported symptoms.
Notifying the registered nurse immediately is the correct action because the client is exhibiting multiple indicators of hypovolemic shock secondary to retroperitoneal hemorrhage. The combination of tachycardia, borderline hypotension, oliguria (urine output less than 30 mL/hr), low hemoglobin, and a new onset of intense pelvic pressure indicates a life-threatening emergency. The practical nurse must promptly escalate these findings to the registered nurse so that rapid, advanced interventions, such as fluid resuscitation, blood transfusions, or surgical stabilization, can be initiated.

Step-by-Step Solution

1
Analyze the client's vital signs and urine output.
Tachycardia, borderline hypotension, and oliguria are present.
To identify early signs of systemic instability or compensatory shock.
2
Evaluate the laboratory results and client symptoms in the context of the initial injury.
A low hemoglobin level and new, intense pelvic pressure strongly indicate active retroperitoneal bleeding from the pelvic fracture.
To correlate subjective complaints and objective data with the high risk of hemorrhage.
3
Determine the appropriate clinical response within the practical nurse scope of practice.
The client is experiencing a life-threatening emergency requiring advanced clinical judgment and rapid intervention.

Select all that apply

Show answer & explanation

Answer: Assist the client into a prone position for twenty to thirty minutes multiple times a day.; Perform routine hygiene by gently cleansing the residual limb with mild soap and warm water.; Encourage and guide the client to perform active range-of-motion exercises using their unaffected limbs.

Answer

The correct basic care interventions include assisting the client into a prone position to prevent contractures, cleansing the residual limb with mild soap and water, and encouraging active range-of-motion exercises for the unaffected limbs.
Proper positioning to prevent contractures, maintaining skin hygiene with appropriate cleansing agents, and preserving muscle strength in unaffected extremities are essential basic care elements that promote comfort and prevent postoperative complications.

Step-by-Step Solution

1
Analyze the client's postoperative timeline and surgical procedure.
The client is on the third day following a below-the-knee amputation.
Care requirements change significantly after the initial postoperative phase, particularly regarding positioning and mobility to prevent complications.
2
Evaluate the positioning option.
The prone position is an appropriate intervention, while elevating the limb on pillows is incorrect.
Prone positioning prevents hip flexion contractures, whereas prolonged pillow elevation after the first day actively causes them.
3
Assess the hygiene and mobility options.
Washing the limb with mild soap and performing active exercises for unaffected limbs are correct basic care actions.
These fundamental actions promote healing, prevent infection, and maintain physical strength for future rehabilitation.
4
Identify procedural and holistic care errors in the remaining options.
Skipping dietary preference checks and utilizing an incorrect personal protective equipment removal order are wrong actions.
Proper basic care requires culturally sensitive nutrition and strict adherence to standard infection control sequences to ensure patient and nurse safety.

Key Concept

Basic care and comfort for an amputation client involves preventing contractures through proper positioning, maintaining skin hygiene, preserving mobility, and providing holistic, culturally competent daily care.
Question 290Question →

A practical nurse is reviewing clinical data for four assigned clients. Which client finding indicates the highest risk for a life-threatening complication and requires immediate communication to the registered nurse?

Show answer & explanation

Answer: A client receiving scheduled nebulized albuterol and intravenous corticosteroids who reports new generalized muscle weakness and a sensation of skipped heartbeats

Answer

The client receiving albuterol and corticosteroids who reports new generalized muscle weakness and a sensation of skipped heartbeats is the priority.
Both albuterol (a beta-2 adrenergic agonist) and corticosteroids lower serum potassium levels. When administered together, the client is placed at high risk for severe hypokalemia. Symptoms such as profound muscle weakness and palpitations (a sensation of skipped heartbeats) strongly indicate a secondary cardiac arrhythmia. This represents an immediate threat to the client's life (Circulation in the ABCs) and requires emergency notification to the registered nurse for rapid medical intervention.

Step-by-Step Solution

1
Analyze the symptoms of the client receiving albuterol and corticosteroids.
The client is experiencing new generalized muscle weakness and skipped heartbeats.
Both albuterol and corticosteroids shift potassium intracellularly or increase its excretion. The combination creates a high risk for severe hypokalemia, which commonly presents as muscle weakness and palpitations, indicating a potentially lethal cardiac arrhythmia.
2
Evaluate the blood glucose level of the client with type 2 diabetes and an active infection.
The fasting capillary blood glucose is 182 mg/dL.
Infection triggers a physiological stress response that predictably elevates blood glucose levels. While abnormal, this is a stable, expected finding that can be managed routinely without an emergency escalation.
3
Assess the clinical priority of the client requesting intravenous push (IVP) morphine.
The client has severe pain requiring medication.
Pain is a critical psychosocial and comfort need, but it does not supersede a physiological airway, breathing, or circulation (ABC) emergency. Furthermore, IVP medications require RN administration and fall outside standard PN scope.
4
Interpret the vital signs of the client with essential hypertension.
Blood pressure is 146/88 mm Hg and heart rate is 82 beats/min.
These are borderline elevated but represent an expected baseline for a client with a history of hypertension, posing no acute or immediate physiological risk.

Question 291Question →

A practical nurse (PN) is providing morning care to a client who is 3 days postoperative following an exploratory laparotomy. The client coughs forcefully and reports a "popping" sensation. The PN observes that the abdominal incision has completely separated, with a loop of bowel protruding. Arrange the following nursing actions in the correct priority sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first call for assistance while staying with the client, then position the client to reduce abdominal tension, cover the exposed organs with moist sterile dressings, obtain vital signs to assess for shock, and finally prepare the client for emergency surgery.
Wound evisceration is an acute medical emergency requiring immediate, stepwise intervention. First, the nurse must call for help while remaining at the bedside to ensure safety and escalate care. Second, placing the client in a low Fowler's position with knees flexed minimizes intra-abdominal pressure and halts further organ protrusion. Third, applying sterile, saline-soaked dressings protects the exposed bowel from ischemia and necrosis. Fourth, monitoring vital signs assesses the client for hemodynamic instability and shock. Finally, ensuring NPO status and preparing the client for surgery addresses the definitive medical treatment.

Step-by-Step Solution

1
Call for immediate assistance while remaining with the client.
Help is summoned without abandoning the unstable client.
Evisceration is a life-threatening surgical emergency requiring a provider and an operating room. The PN must stay with the client to prevent further injury while help is dispatched.
2
Position the client in a low Fowler's position with the knees flexed.
Abdominal muscle tension is minimized.
This specific position relieves pressure on the abdominal cavity, physically preventing further protrusion of the intestines.
3
Cover the protruding bowel with sterile dressings moistened with sterile normal saline.
The exposed bowel is protected from drying and infection.
Exposed internal organs can quickly become ischemic or necrotic if allowed to dry out. A moist, sterile environment preserves tissue viability.
4
Obtain a complete set of vital signs to monitor for signs of shock.
Baseline hemodynamic status is established during the emergency.
The client is at high risk for hypovolemic shock due to fluid shifts and trauma. Vital signs dictate further circulatory interventions.
5
Ensure the client is on strict nothing by mouth (NPO) status and prepare for emergency surgery.
The client is readied for surgical repair.
The definitive treatment for an evisceration is surgical closure. Ensuring NPO status prevents aspiration during the impending administration of anesthesia.

Key Concept

The priority management of an abdominal wound evisceration focuses on immediately securing help, minimizing intra-abdominal pressure, and preserving the viability of the exposed organs without leaving the bedside.
Question 292Question →

A practical nurse (PN) is preparing to administer morning medications, including digoxin and furosemide. When checking the client's chart, the PN discovers a new serum potassium result of 2.62.6 mEq/L. Arrange the following actions in the correct priority sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first withhold the medications, then assess the client's apical pulse, report the findings to the registered nurse, and finally document the actions taken.
When a practical nurse identifies a critical laboratory value such as a potassium level of 2.62.6 mEq/L, the immediate priority is client safety. The PN must first withhold any medications that could exacerbate the condition, such as furosemide (which wastes potassium) and digoxin (which becomes highly toxic in hypokalemia). Next, the PN must assess the client for active complications, specifically checking the apical pulse for arrhythmias. Once the assessment data is collected, the PN reports a complete clinical picture to the RN to facilitate prompt medical intervention. Finally, all findings and actions are thoroughly documented in the electronic health record.

Step-by-Step Solution

1
Withhold the administration of the scheduled digoxin and furosemide.
Further depletion of potassium and potential digoxin toxicity are prevented.
Safety is the initial priority. Furosemide actively depletes potassium, and hypokalemia severely increases the risk of life-threatening digoxin toxicity.
2
Assess the client's apical pulse and observe for signs of profound muscle weakness.
Current clinical data regarding the client's physiological response to hypokalemia is obtained.
The PN must determine if the critical lab value is actively causing adverse effects, such as cardiac arrhythmias, before notifying the healthcare team.
3
Report the critical potassium level and the client's vital signs to the supervising registered nurse.
The registered nurse and healthcare provider are alerted to the emergency.
Escalation is required so the provider can prescribe corrective treatments, such as potassium replacement therapy.
4
Document the withheld medications, assessment findings, and the RN notification in the health record.
A clear, legal record of the clinical event and nursing interventions is created.
Documentation should occur after the client is stabilized and the healthcare team has been notified of the critical findings.

Question 293Question →

While providing morning hygiene and comfort measures for an individual recovering from a recent right posterior total hip arthroplasty, the practical nurse (PN) needs to change the soiled bottom bed linens. Which specific technique must the PN utilize to complete this task safely?

Show answer & explanation

Answer: Secure an abduction device between the thighs and turn the client as a single unit onto their left lateral side.

Answer

The correct action is to secure an abduction device between the thighs and turn the client as a single unit onto their left lateral side.
Following a posterior total hip arthroplasty, the client is at high risk for hip dislocation if the joint is subjected to adduction, internal rotation, or flexion greater than 90 degrees. Placing an abduction wedge or pillow between the legs prevents the affected leg from crossing the midline (adduction) while the client is safely turned onto their unoperated side to facilitate linen changes and back care.

Step-by-Step Solution

1
Identify the client's surgical procedure and associated anatomical risks.
The client had a right posterior total hip arthroplasty, which carries a high risk of dislocation if specific joint movements are permitted.
Understanding surgical precautions is essential before initiating basic care and hygiene interventions.
2
Determine the specific movement restrictions for a posterior surgical approach.
The affected hip must not be flexed beyond 90 degrees, internally rotated, or adducted across the body's midline.
These specific positions force the femoral head out of the newly implanted acetabular cup.
3
Evaluate each proposed hygiene technique against the strict movement restrictions.
Raising the bed causes excessive flexion, removing the wedge causes adduction, and inward rotation is directly contraindicated. Only using an abduction device while turning maintains safety.
Basic care interventions must be fundamentally modified to strictly adhere to postoperative joint precautions.

Question 294Question →

During the morning shift, a practical nurse (PN) is reviewing the electronic health record for a client with pneumonia who recently developed peripheral edema. The new medication prescriptions include oral azithromycin and intravenous (IV) push bumetanide. The client's most recent basic metabolic panel reveals a serum potassium level of 2.82.8 mEq/L (2.82.8 mmol/L). Which is the most appropriate action for the PN to take?

Show answer & explanation

Answer: Withhold the medications, immediately report the critical potassium level to the registered nurse (RN), and clarify that the IV push medication requires RN administration.

Answer

Withhold the medications, immediately report the critical potassium level to the registered nurse (RN), and clarify that the IV push medication requires RN administration.
The client's serum potassium level of 2.82.8 mEq/L is critically low. Bumetanide is a potassium-wasting loop diuretic that would dangerously exacerbate this hypokalemia. Additionally, administering medications via the intravenous (IV) push route is outside the standard scope of practice for a practical nurse (PN). Therefore, the safest and most appropriate action is to withhold the medications and immediately escalate both the critical laboratory value and the administration of the IV push medication to the registered nurse (RN).

Step-by-Step Solution

1
Analyze the client's laboratory results.
The serum potassium level is 2.8 mEq/L, which is critically low (normal range is typically 3.5 to 5.0 mEq/L).
Identifying critical abnormal values is required before administering medications that could worsen the condition or cause fatal dysrhythmias.
2
Evaluate the prescribed medications against the client's condition and the practical nurse (PN) scope of practice.
Bumetanide is a potassium-wasting loop diuretic that would further deplete the client's potassium. Additionally, IV push medications are generally outside the PN scope of practice.
Safe administration requires understanding drug mechanisms, contraindications, and adhering to legal practice boundaries.
3
Determine the priority nursing intervention.
The PN must withhold the medications and immediately escalate the critical laboratory value and the out-of-scope prescription to the RN.
Prompt communication of life-threatening abnormalities and strict adherence to the scope of practice ensures client safety.

Key Concept

Medication safety involves recognizing critical laboratory values (such as hypokalemia), withholding contraindicated drugs (like loop diuretics), and adhering to the legal scope of practice regarding intravenous push administration.

The nurse anticipates contact with copious respiratory secretions. Arrange the following steps for donning the required personal protective equipment (PPE) in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for donning PPE is: 1. Perform hand hygiene, 2. Put on the isolation gown, 3. Apply a surgical mask, 4. Place goggles or a face shield, 5. Don clean gloves.
The Centers for Disease Control and Prevention (CDC) guidelines mandate a specific sequence for donning PPE to maximize protection and prevent contamination. Hand hygiene is always the required first step. The gown is applied first as it is the largest barrier and requires reaching behind the neck and waist. The mask is applied second to secure respiratory protection. Eye protection is added third, resting over the upper edge of the mask. Gloves are applied last so they can be extended over the gown cuffs to seal the wrist area.

Step-by-Step Solution

1
Perform hand hygiene.
Hands are clean before touching PPE.
Prevents the transfer of pathogens to the clean protective equipment.
2
Don the isolation gown.
The torso and arms are protected.
The gown is the bulkiest item and requires tying at the back, which should be done before hand dexterity is reduced by gloves.
3
Apply the surgical mask.
The nose and mouth are protected from droplet splashes.
The mask must be fitted properly to the face before eye protection is added.
4
Place goggles or a face shield.
The eyes are protected from potential secretion splashes.
Eye protection rests over the mask to ensure complete coverage without compromising the mask's fit.
5
Don clean gloves.
The hands and wrists are fully protected.
Pulling gloves over the gown cuffs ensures there is no exposed skin at the wrists.

Question 296Question →

A practical nurse is caring for a 65-year-old client who underwent a total abdominal hysterectomy 4 hours ago. The client becomes restless, reports feeling dizzy, and states, "I am extremely thirsty." Baseline vital signs upon arrival to the unit were blood pressure 124/76 mm Hg, heart rate 82 beats/min, and respiratory rate 16 breaths/min. Current vital signs are blood pressure 104/66 mm Hg, heart rate 110 beats/min, and respiratory rate 22 breaths/min. The visible abdominal dressing is dry and intact. Which action should the practical nurse take first?

Show answer & explanation

Answer: Inspect the perineal pad and the linens beneath the client for pooling blood.

Answer

The practical nurse should first inspect the perineal pad and the linens beneath the client for pooling blood.
The client is exhibiting classic early signs of hypovolemic shock, including restlessness, dizziness, excessive thirst, tachycardia, and a narrowing pulse pressure with hypotension. Since the visible abdominal dressing is dry, the practical nurse must assess for dependent pooling of blood under the client and check the perineal pad for hidden vaginal bleeding. Gathering this complete data is essential before immediately escalating the findings to the registered nurse.

Step-by-Step Solution

1
Analyze the client's vital signs and reported symptoms.
The client has developed tachycardia, mild hypotension, tachypnea, restlessness, dizziness, and extreme thirst compared to baseline.
Comparing current data to baseline is necessary to identify acute changes in condition.
2
Interpret the clinical significance of the changes.
These findings are classic early compensatory mechanisms for hypovolemic shock, likely due to postoperative hemorrhage.
Early recognition of shock is critical for preventing irreversible organ damage.
3
Determine the appropriate focused data collection.
Since the visible abdominal dressing is dry, the nurse must check for hidden bleeding by inspecting the perineal pad and underneath the client.
Blood follows gravity, so dependent pooling or vaginal bleeding are common sources of unseen hemorrhage after a hysterectomy.
4
Prioritize the immediate nursing action.
The practical nurse collects this critical data to complete the assessment before immediately escalating the findings to the registered nurse and provider.
The registered nurse needs complete assessment data to initiate emergency interventions.

Key Concept

During the morning huddle on an acute care unit, the charge nurse delegates various tasks to the nursing staff. Which of the following tasks, involving clients with specific infection risks, falls safely within the scope of practice for a practical nurse (PN) and demonstrates correct isolation protocols?

Show answer & explanation

Answer: Administering a scheduled enteral tube feeding to a client with a Clostridioides difficile infection while wearing a clean gown and gloves

Answer

The task that correctly aligns with both the PN's scope of practice and proper infection control protocols is administering a scheduled enteral tube feeding to a client with a Clostridioides difficile infection while wearing a clean gown and gloves.
Administering an enteral tube feeding is an established, predictable skill within the scope of practice for a practical nurse (PN). Furthermore, wearing a gown and gloves directly adheres to the standard contact precautions required when caring for a client with a Clostridioides difficile infection.

Step-by-Step Solution

1
Evaluate the clinical task in each option to determine if it falls within the legal scope of practice for a practical nurse (PN).
Initial comprehensive assessments, care plan formulation, and intravenous push (IVP) medications are typically outside the PN scope, while enteral tube feedings are permissible.
The PN must always practice within legal and facility boundaries to ensure safe client care.
2
Analyze the infection control and personal protective equipment (PPE) protocols described in the remaining options.
Removing contaminated PPE in the hallway violates transmission-based precaution standards, whereas wearing a gown and gloves for a client with C. difficile is correct.
Proper PPE selection and doffing location (inside the client's room) are required to contain pathogens and prevent cross-contamination.
3
Identify the option that successfully satisfies the requirements for both scope of practice and infection control.
Administering the tube feeding using contact precautions is the only safe and appropriate action.
It successfully applies both delegation boundaries and correct PPE usage for the specified pathogen.

An outpatient clinic practical nurse (PN) is reviewing the health records of several clients scheduled to receive the live-attenuated measles, mumps, and rubella (MMR) vaccine. Which client findings require the PN to withhold the immunization and immediately consult the registered nurse (RN)? Select all that apply.

Select all that apply

Show answer & explanation

Answer: A 24-year-old client who states, "I just found out I am 8 weeks pregnant."; A 45-year-old client currently undergoing immunosuppressive chemotherapy for lymphoma.; A 6-year-old client with a documented severe anaphylactic reaction to a previous dose of the MMR vaccine.

Answer

The findings that require withholding the live-attenuated MMR vaccine are the client who is 8 weeks pregnant, the client undergoing immunosuppressive chemotherapy, and the client with a documented anaphylactic reaction to a previous dose.
Live-attenuated vaccines, such as the MMR vaccine, contain a weakened form of the living virus. They are strictly contraindicated in pregnant clients due to the risk of fetal transmission and teratogenic effects. They are also contraindicated in severely immunocompromised clients (such as those on chemotherapy) because their weakened immune systems cannot safely handle the virus, risking a severe infection. A documented anaphylactic reaction to a previous dose is an absolute contraindication for any medication or vaccine due to the high risk of a life-threatening allergic response upon re-exposure.

Step-by-Step Solution

1
Analyze the medication class.
The MMR vaccine is identified as a live-attenuated virus vaccine.
Different types of vaccines (live vs. inactivated) have distinct safety parameters and contraindications.
2
Recall absolute contraindications for live-attenuated vaccines.
Identified pregnancy, severe immunocompromise (e.g., active chemotherapy), and previous anaphylactic reactions as critical safety risks.
Live vaccines contain a weakened form of the virus that can cause harm in vulnerable or hypersensitive populations.
3
Evaluate the remaining scenarios to differentiate true contraindications from false contraindications.
Determined that mild acute illnesses, normal laboratory values, and normal pediatric vital signs are safe conditions for administration.
Recognizing false contraindications prevents unnecessary delays in vital immunizations.
4
Select the client scenarios that present true contraindications.
Selected the pregnant client, the chemotherapy client, and the client with a prior anaphylactic reaction as requiring immediate RN consultation.
The PN must practice within scope by identifying unsafe medication parameters and withholding administration until evaluated by the RN.

An unresponsive client requires oral hygiene to maintain mucosal integrity. In which order should the practical nurse perform the following actions to complete this procedure safely? Arrange the steps in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first position the client side-lying, place protective linens and a basin, safely open the mouth with a padded tongue blade, perform the cleaning with simultaneous suctioning, and finally moisturize the lips.
When providing oral hygiene to an unresponsive client, safety—specifically airway protection—is the absolute highest priority. Therefore, the client must first be turned to a side-lying position to utilize gravity for drainage. Once positioned safely, the nurse prepares the area with a towel and basin to maintain cleanliness. Next, safe access to the oral cavity is secured using a padded tongue blade, preventing injury from reflex biting. The actual cleaning is then performed simultaneously with suctioning to ensure no fluid accumulates in the airway. Finally, the procedure concludes with a comfort measure, applying water-soluble lubricant to prevent the lips from drying and cracking.

Step-by-Step Solution

1
Assist the client into a side-lying position.
The client is in a safe posture for oral care.
The side-lying position allows fluids to pool in the side of the mouth and drain out, significantly reducing the risk of aspiration.
2
Place a towel under the client's chin and an emesis basin against the cheek.
The physical environment is prepared.
This step protects the client's gown and linens from becoming soiled and provides a receptacle for the oral drainage.
3
Insert a padded tongue blade gently between the back molars to open the mouth.
The oral cavity is safely accessed.
An unresponsive client may bite down reflexively. Using a padded tongue blade protects both the client's teeth and the nurse's fingers.
4
Clean the teeth and oral mucosa using a moistened swab while applying suction.
The mouth is cleaned and secretions are removed.
Cleaning removes plaque and bacteria. Continuous or intermittent suctioning ensures that the fluid used for cleaning and any loosened secretions are not aspirated into the lungs.
5
Apply a water-soluble lubricant to the client's lips.
The client's lips are protected from cracking.
Unresponsive clients often breathe through their mouths, leading to dry lips. A water-soluble lubricant maintains tissue integrity without the flammability risk associated with petroleum-based products.

Question 300Question →

An elderly client is receiving care in a subacute rehabilitation facility following a recent lower respiratory tract infection. While completing evening rounds, the practical nurse (PN) collects data on the client's current physiological status. Which of the following assessment findings require immediate escalation to the registered nurse (RN) for suspected clinical deterioration? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Sudden onset of agitation and disorientation to time and place.; Heart rate of 114 beats per minute with a blood pressure of 98/60 mm Hg.; Respiratory rate of 28 breaths per minute with the use of accessory muscles.

Answer

The findings requiring immediate escalation are the sudden onset of agitation and disorientation, the heart rate of 114 beats per minute with a blood pressure of 98/60 mm Hg, and the respiratory rate of 28 breaths per minute with the use of accessory muscles.
The correct findings directly point to acute physiological decompensation. Tachypnea with accessory muscle use is a clear sign of respiratory distress (Breathing). Tachycardia with borderline hypotension suggests early shock or sepsis (Circulation). Sudden agitation and disorientation are classic early signs of hypoxia or poor cerebral perfusion in older adults. All of these require immediate RN notification to prevent further decline.

Step-by-Step Solution

1
Analyze the client's clinical scenario.
The client is an older adult recovering from a respiratory infection, making them vulnerable to sepsis, hypoxia, and shock.
Understanding the baseline risk factors helps in identifying which signs represent acute complications.
2
Evaluate each finding using the Airway, Breathing, and Circulation (ABC) prioritization framework.
Respiratory rate of 28 with accessory muscle use affects Breathing. Heart rate of 114 with BP of 98/60 affects Circulation. Sudden agitation indicates altered brain perfusion, which is tied to ABCs.
ABCs take immediate precedence in physiological adaptation and emergency recognition.
3
Differentiate between acute deterioration and expected or stable findings.
Mild IV site pain, formed bowel movements, and a 95% oxygen saturation are stable, non-emergent findings.
Escalation to the RN is reserved for findings that indicate a life-threatening change in condition.
