Question 621Question →

During afternoon rounds, a client who underwent a percutaneous liver biopsy three hours ago reports feeling unusually thirsty and lightheaded. The practical nurse obtains the following vital signs: heart rate 114 bpm, blood pressure 96/58 mm Hg, and respiratory rate 22 breaths/min. The client's baseline blood pressure prior to the procedure was 128/74 mm Hg. Based on these findings, which action should the nurse take first?

Show answer & explanation

Answer: Notify the supervising registered nurse immediately.

Answer

The correct action is to notify the supervising registered nurse immediately.
The correct response demonstrates the practical nurse's ability to recognize a life-threatening physiological adaptation (internal bleeding leading to hypovolemic shock) and take the appropriate priority action within their scope of practice, which is immediate escalation to the registered nurse.

Step-by-Step Solution

1
Analyze the client's presenting symptoms and vital signs against their baseline.
The client has developed tachycardia (114 bpm), hypotension (drop from 128/74 to 96/58), thirst, and lightheadedness.
Identifying acute changes from baseline is essential for early recognition of postoperative complications.
2
Correlate the findings with the recent procedure (liver biopsy).
The liver is highly vascular, making internal hemorrhage a primary risk following a biopsy. The symptoms directly align with hypovolemic shock.
Connecting physiological data to the client's clinical history helps determine the severity and nature of the emergency.
3
Determine the priority nursing action based on the practical nurse scope of practice.
The most critical action is to immediately escalate the findings to the registered nurse or healthcare provider.
Acute physiological decompensation requires immediate advanced intervention (such as IV fluids, blood products, or surgery) which must be initiated by the RN or provider.

Question 622Question →

A practical nurse is preparing to administer a prescribed dose of oral amoxicillin suspension to a pediatric client who weighs 14 kg14 \text{ kg}. The provider's prescription states: amoxicillin 40 mg/kg/day40 \text{ mg/kg/day} by mouth divided into two equal doses every 1212 hours. The pharmacy dispenses amoxicillin suspension at a concentration of 250 mg/5 mL250 \text{ mg}/5 \text{ mL}. How many mL\text{mL} should the nurse administer per dose? (Record your answer to the nearest tenth. Do not include units in your answer.)

Show answer & explanation

Answer: 5.6

Answer

The nurse should administer 5.6 mL per dose.
To ensure safe medication administration, the nurse must accurately convert the prescribed weight-based parameter into a measurable fluid volume. By calculating the total daily dose (560 mg560 \text{ mg}), dividing it into the specified two doses (280 mg280 \text{ mg} each), and applying the concentration formula (DesiredHave×Volume\frac{\text{Desired}}{\text{Have}} \times \text{Volume}), the correct verifiable dose is 5.6 mL5.6 \text{ mL}.

Step-by-Step Solution

1
Determine the total daily dose in milligrams based on the client's weight.
14 kg×40 mg/kg=560 mg/day14 \text{ kg} \times 40 \text{ mg/kg} = 560 \text{ mg/day}
Weight-based prescriptions require calculating the total 24-hour medication allowance before determining individual dose amounts.
2
Determine the individual dose amount in milligrams.
560 mg÷2=280 mg/dose560 \text{ mg} \div 2 = 280 \text{ mg/dose}
The prescription specifies that the total daily amount must be divided into two equal doses administered every 12 hours.
3
Calculate the liquid volume to administer per dose using the supplied concentration.
(280 mg250 mg)×5 mL=5.6 mL(\frac{280 \text{ mg}}{250 \text{ mg}}) \times 5 \text{ mL} = 5.6 \text{ mL}
This converts the required milligram dose into the measurable milliliter volume provided by the pharmacy.

An LPN/LVN is assigned to care for a client recovering from a partial colectomy performed earlier in the day. The client's current vital signs reveal a heart rate of 114114 beats/minute, a blood pressure of 96/5896/58 mm Hg, and a respiratory rate of 2222 breaths/minute. Simultaneously, the electronic health record alerts the nurse to a newly resulted serum hemoglobin level of 7.37.3 g/dL. Based on these clinical findings, what is the most appropriate initial action?

Show answer & explanation

Answer: Immediately alert the registered nurse about the client's vital signs and the recent blood work.

Answer

Immediately alert the registered nurse about the client's vital signs and the recent blood work.
The correct response demonstrates the practical nurse's ability to identify a high-risk postoperative complication (hemorrhage leading to hypovolemic shock) by recognizing the combination of tachycardia, borderline hypotension, and a critical hemoglobin level. Immediate escalation to the registered nurse is the safest and most appropriate action within the LPN/LVN scope of practice to reduce client risk.

Step-by-Step Solution

1
Analyze the vital signs in the context of the surgical procedure.
The heart rate of 114114 beats/minute and blood pressure of 96/5896/58 mm Hg indicate tachycardia and borderline hypotension, which are early signs of compensatory shock following a major abdominal surgery.
Recognizing subtle shifts in vital signs is essential for early identification of postoperative hemorrhage.
2
Evaluate the newly resulted laboratory value.
A hemoglobin level of 7.37.3 g/dL is critically low and corroborates the vital sign trends, pointing toward active bleeding.
Correlating clinical presentation with diagnostic data confirms the severity of the client's condition.
3
Determine the appropriate nursing intervention within the LPN/LVN scope of practice.
The nurse must escalate the findings to the registered nurse or healthcare provider immediately.
Practical nurses must recognize complications and escalate care for interventions that fall outside their scope, such as administering blood products or altering the medical plan of care.

Question 624Question →

An LPN/LVN is assisting a female client with limited mobility in collecting a midstream clean-catch urine specimen. To reduce the risk of sample contamination, arrange the following steps in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The nurse should first perform hand hygiene and don gloves, then cleanse the meatus from front to back. Next, the client should begin voiding to flush the urethra. The nurse then catches the midstream sample and removes the cup before the voiding is complete.
To obtain an uncontaminated midstream clean-catch urine specimen, the nurse must follow a strict procedural sequence: apply personal protective equipment, cleanse the meatus from front to back, allow the initial stream to flush the urethra, collect the midstream sample, and remove the cup before the client finishes voiding. This ensures the laboratory results reflect the actual bladder contents rather than external flora.

Step-by-Step Solution

1
Perform hand hygiene and apply clean exam gloves.
The nurse is prepared to assist the client using standard precautions.
Prevents the introduction of the nurse's flora to the client and protects the nurse from exposure to body fluids.
2
Cleanse the urethral meatus using antiseptic wipes in a front-to-back motion.
The external genitalia are cleansed of surface bacteria.
Front-to-back cleansing prevents the introduction of gastrointestinal pathogens into the urinary tract and specimen.
3
Direct the client to begin voiding a small amount of urine into the toilet or bedpan.
The distal urethra is flushed with the initial flow of urine.
The initial stream clears microorganisms that naturally colonize the urethral opening.
4
Position the sterile collection cup into the active stream of urine.
The midstream urine is collected in the sterile container.
Midstream urine provides the most accurate reflection of bladder contents for laboratory testing.
5
Remove the specimen container from the stream before the client completely finishes voiding.
The collection is completed without contamination from the end of the urinary stream.
The final drops of urine can pick up skin flora from the external genitalia, potentially skewing the test results.

Key Concept

The purpose of a midstream clean-catch urine specimen is to obtain a sample that is free of external contamination. Proper sequencing ensures that external flora and urethral contaminants are cleared before the actual sample is collected into the sterile container.

Question 625Question →

During a shift at a community health clinic, a practical nurse evaluates clients presenting for scheduled immunizations. Which clients can safely undergo their prescribed vaccination therapies today? (Select all that apply)

Select all that apply

Show answer & explanation

Answer: A pediatric client with a low-grade fever and clear nasal discharge scheduled for the measles, mumps, and rubella (MMR) vaccine.; An adolescent client who experienced mild injection site erythema after a previous dose, scheduled for a Tdap booster.

Answer

The clients who can safely receive their vaccines are the child with a mild respiratory illness and the adolescent with a history of a mild localized injection reaction.
Mild acute illnesses, such as an upper respiratory infection with a low-grade fever, do not necessitate withholding vaccines like the MMR. Similarly, a mild localized reaction (erythema or soreness) to a previous vaccine dose is a normal expected finding and is not a contraindication for receiving subsequent boosters like the Tdap.

Step-by-Step Solution

1
Evaluate each client's current health status and medical history against the type of vaccine ordered (live-attenuated versus inactivated).
Identified which clients have conditions that interact negatively with the specific vaccine components.
Different vaccine formulations carry distinct risks; live vaccines require an intact immune system and are generally avoided during pregnancy.
2
Differentiate between true contraindications and general precautions or expected side effects.
Determined that a mild cold (low-grade fever) and prior localized erythema are not reasons to withhold immunization.
Delaying vaccines for minor illnesses creates missed opportunities for critical disease prevention.
3
Identify absolute contraindications for the specific vaccines listed in the scenario.
Recognized that pregnancy, severe immunosuppression from corticosteroids, and a history of intussusception are major safety risks.
Administering live vaccines to immunocompromised or pregnant clients, or the rotavirus vaccine to an infant with a history of bowel telescoping, can cause severe harm.

An older adult client diagnosed with heart failure is prescribed a daily scheduled dose of oral spironolactone. During the morning chart review, the practical nurse notes that the client's most recent serum potassium level is 5.8 mEq/L5.8 \text{ mEq/L}. Which action should the practical nurse take next?

Show answer & explanation

Answer: Withhold the spironolactone and promptly report the potassium level to the registered nurse.

Answer

Withhold the spironolactone and promptly report the potassium level to the registered nurse.
Spironolactone is a potassium-sparing diuretic that can cause or worsen hyperkalemia. A serum potassium level of 5.8 mEq/L5.8 \text{ mEq/L} is elevated above the normal expected range. Administering the medication under these conditions could lead to severe cardiac dysrhythmias. The practical nurse must withhold the medication and immediately notify the registered nurse or healthcare provider to ensure patient safety.

Step-by-Step Solution

1
Analyze the client's laboratory result.
The serum potassium level is 5.8 mEq/L5.8 \text{ mEq/L}, which indicates hyperkalemia (normal range is typically 3.53.5 to 5.0 mEq/L5.0 \text{ mEq/L}).
Recognizing abnormal laboratory values is essential before medication administration.
2
Identify the mechanism of the prescribed medication.
Spironolactone is a potassium-sparing diuretic.
Understanding the drug class helps predict how it will affect the client's current physiological state.
3
Determine the risk of administration.
Giving a potassium-sparing drug to a hyperkalemic client will dangerously increase potassium levels, risking fatal cardiac dysrhythmias.
Client safety is the primary priority when deciding whether to administer or withhold a drug.
4
Select the appropriate nursing intervention.
The practical nurse must withhold the dose and escalate the finding to the registered nurse.
This action remains within the practical nurse's scope of practice while preventing immediate harm to the client.

During a shift on a surgical unit, a practical nurse is evaluating a client who underwent a partial nephrectomy 4 hours4\text{ hours} ago. The client's current vital signs include a heart rate of 116 beats/min116\text{ beats/min} and a blood pressure of 94/58 mm Hg94/58\text{ mm Hg}. The electronic health record displays a recent postoperative serum hemoglobin level of 11.0 g/dL11.0\text{ g/dL}. The client is awake and reporting moderate incisional pain. Which action should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the client's current vital signs.

Answer

The practical nurse must immediately notify the registered nurse about the abnormal vital signs.
The correct action prioritizes airway, breathing, and circulation (ABC) principles. Tachycardia combined with borderline hypotension in a client recovering from a highly vascular surgery (partial nephrectomy) strongly suggests acute hemorrhage and early hypovolemic shock. The practical nurse must recognize this life-threatening risk potential and immediately escalate the findings to the registered nurse for rapid intervention.

Step-by-Step Solution

1
Analyze the client's vital signs in the context of the postoperative timeline.
The heart rate of 116 beats/min116\text{ beats/min} and blood pressure of 94/58 mm Hg94/58\text{ mm Hg} represent a significant deviation from expected stability for a client 4 hours4\text{ hours} post-nephrectomy.
Identifying subtle deviations in baseline vital signs is the first step in recognizing physiological instability.
2
Evaluate the laboratory data and client symptoms.
The hemoglobin is mildly low (11.0 g/dL11.0\text{ g/dL}) but anticipated after surgery, and moderate pain is a normal postoperative finding.
Differentiating between expected postoperative findings and emergent complications prevents incorrect prioritization.
3
Correlate the abnormal vital signs with surgical risk factors.
The unexplained tachycardia and borderline hypotension point to early hypovolemic shock, strongly suggesting hemorrhage at the highly vascular kidney surgical site.
Understanding the physiological implications of specific procedures helps anticipate severe complications.
4
Determine the safest priority action within the practical nursing scope of practice.
The nurse must escalate this critical change in condition to the registered nurse for advanced assessment and collaborative intervention.
Timely communication of a deteriorating client status is essential to reduce the risk of adverse physiological outcomes.

Question 628Question →

A practical nurse is preparing to administer prescribed ophthalmic drops to a client diagnosed with glaucoma. Arrange the steps of the procedure in the correct chronological order. All steps must be used.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

First cleanse the eye from inner to outer canthus, then position the client looking up, expose the conjunctival sac, instill the drops into the sac, and finally apply pressure to the nasolacrimal duct.
This chronological sequence ensures optimal medication delivery while prioritizing client safety. Cleaning the eye prevents infection, correct positioning reduces the blink reflex, exposing the sac ensures accurate delivery, and nasolacrimal pressure limits unintended systemic absorption.

Step-by-Step Solution

1
Cleanse the eyelid and eyelashes.
The eye area is free of drainage and debris.
Wiping from the inner to outer canthus prevents sweeping pathogens into the nasolacrimal duct.
2
Position the client's head backward and instruct them to look up.
The cornea rotates away from the lower lid.
Looking up decreases the natural blink reflex and prevents the medication drop from directly hitting the sensitive cornea.
3
Pull the lower eyelid downward.
The conjunctival sac is exposed.
This creates a trough or pocket to safely catch and hold the liquid medication.
4
Instill the prescribed number of drops into the conjunctival sac.
The medication is delivered to the eye.
Holding the dropper 1 to 2 cm away prevents accidental contact with the eye, which could cause injury or contaminate the dropper.
5
Apply gentle pressure to the nasolacrimal duct.
The tear duct is temporarily occluded.
Occluding the duct prevents the medication from draining into the nasal cavity and entering the systemic circulation, reducing the risk of systemic side effects.

While observing a 75-year-old client admitted earlier today with a closed pelvic fracture, the practical nurse notes the client is newly restless, mildly confused, and repeatedly asking for a drink. The client's current vital signs reveal a blood pressure of 102/66 mm Hg, a heart rate of 108 beats/min, and a respiratory rate of 22 breaths/min. Which of the following actions is the priority for the practical nurse?

Show answer & explanation

Answer: Report the client's vital signs and behavioral changes to the registered nurse immediately

Answer

Report the client's vital signs and behavioral changes to the registered nurse immediately.
The correct action is to report the findings because the client is exhibiting early signs of hypovolemic shock (restlessness, confusion, thirst, tachycardia, and borderline hypotension), a life-threatening complication of pelvic fractures. The practical nurse must prioritize Circulation (ABCs) and immediately escalate these findings to the registered nurse for prompt intervention.

Step-by-Step Solution

1
Analyze the client's current clinical presentation and vital signs.
The client is restless, confused, thirsty, and has borderline tachycardia (108 beats/min) and lower-end blood pressure (102/66 mm Hg).
Identifying abnormal clinical data is the first step in clinical judgment.
2
Connect the symptoms to the client's primary diagnosis of a pelvic fracture.
Pelvic fractures carry a high risk for massive internal retroperitoneal hemorrhage.
Understanding the complications associated with the diagnosis guides the interpretation of the symptoms.
3
Prioritize the required intervention based on the ABCs (Airway, Breathing, Circulation) and scope of practice.
The practical nurse identifies a Circulation emergency and must immediately escalate the findings.
Early hypovolemic shock is a medical emergency that requires rapid RN and provider intervention.

Question 630Question →

A practical nurse is preparing to administer scheduled morning medications to a client who is nonverbal and experiencing acute delirium. The client's family is not currently present in the room. Which action describes the correct method for verifying this client's identity prior to medication administration?

Show answer & explanation

Answer: Compare the name and date of birth on the client's attached identification band with the electronic medication administration record.

Answer

Compare the name and date of birth on the client's attached identification band with the electronic medication administration record.
Safe medication administration requires verifying at least two distinct patient identifiers, such as the client's full name and date of birth. For a client who is nonverbal and confused, the nurse cannot rely on verbal confirmation and must instead use objective, attached identifiers by comparing the client's physical wristband directly to the electronic medication administration record.

Step-by-Step Solution

1
Assess the client's cognitive and communication status.
The client is identified as nonverbal and experiencing acute delirium.
Determines that the client cannot self-report their name and date of birth.
2
Determine the acceptable alternative method for patient identification.
Objective, physical identifiers must be used in place of verbal confirmation.
Safety protocols mandate the use of two distinct identifiers regardless of the client's mental status.
3
Locate the client's physical identification band and compare it to the medication administration record (MAR).
The nurse verifies the client's name and date of birth.
This fulfills the 'right client' requirement of the rights of medication administration.

A practical nurse (PN) is assigned to a 78-year-old client who sustained a fractured right femur 24 hours ago. The client, who has a history of mild cognitive impairment, suddenly becomes highly agitated, attempts to pull out the intravenous (IV) line, and develops a respiratory rate of 28 breaths/minute with newly noted petechiae on the upper chest. Which actions should the PN take? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Apply a pulse oximeter to measure the client's oxygen saturation.; Request immediate assistance from the registered nurse (RN) to evaluate the client.; Elevate the head of the client's bed to a semi-Fowler's or high-Fowler's position.

Answer

The practical nurse should apply a pulse oximeter, request immediate assistance from the registered nurse, and elevate the head of the bed.
The client's presentation of sudden agitation, tachypnea, and a petechial rash on the upper chest 24 hours after a femur fracture is the classic triad of fat embolism syndrome. This is a medical emergency causing severe hypoxia. The practical nurse must immediately address the client's respiratory status (Breathing) by elevating the head of the bed to facilitate lung expansion, applying a pulse oximeter to gather objective data on oxygenation, and urgently notifying the registered nurse to coordinate emergency interventions.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has a long bone fracture and suddenly presents with acute agitation, tachypnea (28 breaths/min), and chest petechiae.
Identifying these specific cues is necessary to recognize fat embolism syndrome, a life-threatening complication of long bone fractures.
2
Determine the highest priority of care based on the ABC (Airway, Breathing, Circulation) framework.
The client is exhibiting signs of severe respiratory compromise (Breathing) and acute hypoxia.
Prioritizing ABCs ensures that life-threatening conditions are addressed first.
3
Select the nursing actions that immediately address the physiological crisis within the PN scope of practice.
Elevating the head of the bed, measuring oxygen saturation, and escalating to the RN are immediate, scope-appropriate actions.

Question 633Question →

A practical nurse is caring for a client who is scheduled to receive a morning dose of oral furosemide. During the pre-administration assessment, the nurse notes the client's blood pressure is 86/52 mm Hg, heart rate is 114 beats/min, and the morning serum potassium level is 3.1 mEq/L (3.1 mmol/L). Which action should the practical nurse take?

Show answer & explanation

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

Answer

The practical nurse should withhold the furosemide and immediately report the findings to the registered nurse.
The correct action is to withhold the medication and notify the registered nurse. Furosemide is a loop diuretic that promotes the excretion of water and potassium. The client is already exhibiting signs of hypovolemia (hypotension and tachycardia) and hypokalemia (potassium 3.1 mEq/L, normal is 3.5-5.0 mEq/L). Administering furosemide would worsen both conditions, potentially leading to severe cardiovascular collapse or lethal dysrhythmias. The practical nurse must recognize these critical findings, withhold the drug, and escalate the situation.

Step-by-Step Solution

1
Analyze the client's vital signs and laboratory results.
The blood pressure (86/52 mm Hg) and heart rate (114 beats/min) indicate potential hypovolemia. The potassium level (3.1 mEq/L) indicates hypokalemia.
Pre-administration assessment is critical to ensure medication safety and identify contraindications.
2
Evaluate the pharmacological effects of furosemide against the client's current status.
Furosemide is a loop diuretic that causes fluid loss (lowering blood pressure) and potassium excretion (worsening hypokalemia).
Administering the drug would exacerbate the client's current dangerous physiological state.
3
Determine the appropriate nursing intervention based on the practical nurse scope of practice.
The safest and most appropriate action is to withhold the medication and escalate the critical findings to the supervising registered nurse or healthcare provider.
Practical nurses must recognize adverse conditions, withhold unsafe medications, and communicate findings promptly.

Select all that apply

Show answer & explanation

Answer: Asking an alert client to state their full name and date of birth while comparing it to the medication administration record.; Withholding a scheduled oral beta-blocker and notifying the registered nurse when the client's apical heart rate is 50 beats per minute.

Answer

The correct actions are verifying the client's identity using their full name and date of birth, and withholding the beta-blocker for a heart rate of 50 beats per minute.
Safe pharmacological practice requires strict adherence to the rights of medication administration and operating within the legal scope of practice. Using two distinct, unique identifiers (like name and date of birth) ensures the medication is given to the correct individual. Additionally, assessing critical vital signs, such as an apical pulse, before administering medications like beta-blockers and withholding the dose if the heart rate is too low prevents dangerous adverse cardiac effects.

Step-by-Step Solution

1
Analyze each planned medication administration action against the practical nurse scope of practice and general pharmacological safety standards.
Identified that checking two standard identifiers (name and date of birth) and withholding a beta-blocker for bradycardia are appropriate and safe nursing actions.
These actions directly uphold the rights of medication administration and ensure patient safety by preventing errors and adverse drug events.
2
Evaluate the remaining actions for safety and scope of practice violations.
Identified that IV push administration, giving live vaccines to pregnant clients, using room numbers for identification, and improperly rounding pediatric doses are all unsafe or out of scope.
Recognizing unsafe practices prevents patient harm and ensures adherence to legal guidelines and facility policies regarding safe medication administration.

15:00118/74 mm Hg90 beats/min18 breaths/min
18:00100/62 mm Hg114 beats/min22 breaths/min

While the nurse is collecting data at 18:00, the client states, 'I feel really dizzy and my stomach feels unusually tight.' Which action should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse or charge nurse immediately

Answer

The correct action is to notify the registered nurse or charge nurse immediately because the client is exhibiting classic signs of internal hemorrhage and developing hypovolemic shock.
The correct action focuses on immediate escalation. The client's vital signs show a clear trend of increasing heart rate and decreasing blood pressure over 6 hours. When combined with symptoms of dizziness and abdominal tightness following a major abdominal procedure, these are classic indicators of internal bleeding and hypovolemic shock. The practical nurse must rapidly report these findings to the registered nurse so collaborative emergency interventions can be initiated.

Step-by-Step Solution

1
Analyze the vital sign trends from 12:00 to 18:00.
The blood pressure is steadily decreasing (132/82 mm Hg down to 100/62 mm Hg) while the heart rate is significantly increasing (74 to 114 beats/min).
Identifying trends is crucial for recognizing early physiological instability before a critical event occurs.
2
Correlate the vital signs with the client's symptoms and surgical history.
The client had a major abdominal surgery (hysterectomy) and now reports dizziness and a tight abdomen, which aligns with the deteriorating vital signs.
These combined findings strongly suggest intra-abdominal bleeding leading to hypovolemic shock.
3
Determine the appropriate practical nurse (PN) scope of practice.
The PN must immediately escalate these critical findings to the registered nurse (RN) or healthcare provider.
The client requires rapid assessment and intervention (e.g., fluid resuscitation, potential return to surgery) that falls outside the independent scope of the PN.

Reduction of Risk Potential: Recognizing Postoperative Complications
Question 636Question →

A practical nurse is caring for a client with heart failure who is receiving prescribed intravenous furosemide therapy. Which of the following assessment findings indicate a potential complication and require immediate escalation to the registered nurse? Select all that apply.

Select all that apply

Show answer & explanation

Answer: A serum potassium level of 2.8 mEq/L2.8\text{ mEq/L} (2.8 mmol/L2.8\text{ mmol/L}); New-onset premature ventricular contractions noted on the cardiac telemetry monitor; A decrease in blood pressure from 142/86 mmHg142/86\text{ mmHg} to 88/52 mmHg88/52\text{ mmHg}

Answer

The findings requiring immediate escalation are the critically low serum potassium level, the new-onset premature ventricular contractions, and the significant decrease in blood pressure.
Intravenous furosemide causes rapid fluid and electrolyte shifts. A serum potassium level of 2.8 mEq/L2.8\text{ mEq/L} indicates severe hypokalemia (normal range is 3.53.5 to 5.0 mEq/L5.0\text{ mEq/L}), placing the client at high risk for life-threatening dysrhythmias, such as the newly noted premature ventricular contractions. Furthermore, a significant drop in blood pressure to 88/52 mmHg88/52\text{ mmHg} indicates potential hypovolemia from excessive fluid loss. All three of these findings represent immediate safety risks that fall outside the practical nurse's scope to manage independently and require urgent escalation to the registered nurse.

Step-by-Step Solution

1
Analyze the prescribed medication and the client's underlying condition.
Furosemide is a potent loop diuretic used to treat fluid overload in heart failure by increasing the renal excretion of water, sodium, and potassium.
Understanding the mechanism of action is necessary to anticipate both the intended therapeutic effects and the potential adverse events.
2
Evaluate each assessment finding to determine if it is an expected outcome or a dangerous complication.
High urine output and moderate weight loss are expected therapeutic effects. Conversely, severe hypotension, significant hypokalemia, and new-onset dysrhythmias are adverse effects indicating systemic instability.
Distinguishing between expected physiological responses and abnormal, high-risk findings is the core of clinical judgment.
3
Determine the appropriate nursing action based on the practical nurse scope of practice.
The expected findings are documented and monitored. The adverse findings represent immediate safety risks that must be urgently reported to the registered nurse for medical intervention.
Timely escalation of critical changes reduces the risk potential and ensures the client receives appropriate, advanced care.

Show answer & explanation

Answer: Inspect the surgical dressing and drainage device for excessive bleeding.

Answer

Inspect the surgical dressing and drainage device for excessive bleeding.
The client's new onset of confusion, pale skin, and slight tachycardia are early clinical indicators of inadequate tissue perfusion and possible hypovolemic shock, which is a major physiological complication following major orthopedic surgery. The priority action for the practical nurse is to assess the client's circulation by inspecting the surgical site and drainage systems for active hemorrhage.

Step-by-Step Solution

1
Analyze the client's clinical presentation and vital signs.
The client presents with new-onset confusion, pale skin, slight tachycardia (108 beats/min), and a borderline low blood pressure.
Identifying abnormal data is the first step in clinical reasoning and recognizing physiological compromise.
2
Correlate the assessment findings with potential postoperative complications.
These findings are early compensatory signs of hypovolemic shock, likely caused by postoperative hemorrhage.
Connecting data to potential physiological adaptations determines the severity and urgency of the situation.
3
Determine the priority nursing action based on the ABCs (Airway, Breathing, Circulation).
The most urgent need is to assess for the source of circulatory compromise by inspecting the surgical site.
Because circulation is compromised, identifying active bleeding is the highest priority before escalating the findings to the RN or provider.

Key Concept

Early recognition of hypovolemic shock involves identifying subtle vital sign changes and altered mental status, requiring immediate assessment for bleeding.

A licensed practical nurse (LPN) is reviewing the morning laboratory results for a client who is receiving a continuous intravenous heparin infusion for a deep vein thrombosis. The client's results are as follows:

* Hemoglobin: 13.8 g/dL
* Platelets: 82,000/mm³ (admission baseline: 250,000/mm³)
* Activated partial thromboplastin time (aPTT): 68 seconds (control: 30 seconds)

Based on these findings, which action should the LPN take next?

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the significant decrease in the platelet count.

Answer

The correct action is to notify the registered nurse immediately regarding the significant decrease in the platelet count.
The client's platelet count has dropped by more than 50% from the baseline, which is a strong clinical indicator of heparin-induced thrombocytopenia (HIT). While the aPTT is therapeutic, the critical drop in platelets requires immediate escalation to the registered nurse or healthcare provider. HIT is a life-threatening complication that necessitates stopping the heparin and starting an alternative anticoagulant, an intervention that must be coordinated by the registered nurse and provider.

Step-by-Step Solution

1
Analyze the provided laboratory results.
The hemoglobin is normal, and the aPTT is within the therapeutic range for a heparin infusion (1.5 to 2.5 times the control). However, the platelet count has dropped significantly from the admission baseline.
Identifying abnormal or critical laboratory values is a fundamental step in risk reduction.
2
Identify the potential clinical complication.
A sudden, drastic drop in platelets (more than 50% from baseline) in a client receiving heparin indicates a high probability of heparin-induced thrombocytopenia (HIT), a life-threatening complication.
Recognizing early signs of life-threatening trends is essential for client safety.
3
Determine the appropriate nursing action within the practical nurse scope of practice.
The LPN must immediately report this critical laboratory finding to the registered nurse (RN) or healthcare provider for further intervention, as the heparin infusion will likely need to be discontinued.
Practical nurses are responsible for data collection and the prompt escalation of critical findings to the directing RN.

A practical nurse is preparing to administer a newly prescribed transdermal nitroglycerin patch to a client with a history of stable angina. Arrange the steps of this medication administration procedure in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first don clean gloves, remove the old patch and clean the site, label the new patch, apply it to a suitable hairless area, and finally press it firmly into place without massaging.
Safe application of a transdermal nitroglycerin patch requires a systematic approach to protect both the client and the nurse. The nurse must first wear gloves to prevent self-dosing, then remove the previous patch to prevent overdose. Labeling the new patch prior to application ensures proper documentation without pressing a pen into the client. Finally, selecting a hairless site and pressing without massaging ensures the drug is absorbed at a safe, controlled rate.

Step-by-Step Solution

1
Protect the nurse from unintended medication exposure.
Don clean gloves.
Nitroglycerin is readily absorbed through the skin. Handling the patch with bare hands can cause the nurse to experience adverse effects.
2
Prepare the client for the new dose.
Remove the old patch and wash the old site.
Leaving an old patch on while applying a new one leads to toxicity and nitrate tolerance. Washing removes leftover medication residue.
3
Prepare the new medication for tracking.
Label the new patch with the date, time, and initials.
Writing on the patch before applying it ensures necessary communication with the healthcare team and prevents applying pressure from a pen directly onto the client's body.
4
Administer the medication.
Place the patch on a hairless, intact area of skin.
Scar tissue, cuts, or thick hair can alter the absorption rate of the transdermal medication.
5
Secure the medication.
Press firmly for 10 seconds without rubbing.
Friction from massaging increases local circulation, which can cause an unsafe, rapid absorption of the vasodilator.

A practical nurse (PN) is caring for an 82-year-old client who is receiving a continuous intravenous heparin infusion for a right leg deep vein thrombosis (DVT). The client suddenly becomes highly restless, reports feeling short of breath, and exhibits a respiratory rate of 28 breaths/min. Which of the following actions should the PN take? (Select all that apply)

Select all that apply

Show answer & explanation

Answer: Elevate the head of the client's bed.; Notify the registered nurse (RN) immediately.; Obtain the client's pulse oximetry reading and complete vital signs.

Answer

The correct actions are to elevate the head of the client's bed, immediately notify the registered nurse, and obtain the client's pulse oximetry and complete vital signs.
The client is exhibiting signs of acute hypoxia, potentially due to a pulmonary embolism arising from the deep vein thrombosis. Immediate interventions must focus on Airway, Breathing, and Circulation (ABC). Elevating the head of the bed facilitates lung expansion. Obtaining full vital signs provides critical data, and notifying the RN ensures the client receives prompt emergency medical management.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has sudden shortness of breath, tachypnea (28 breaths/min), and new-onset restlessness.
These are hallmark manifestations of a pulmonary embolism, a life-threatening complication of deep vein thrombosis causing acute hypoxia.
2
Determine the priority interventions based on the ABC framework.
Airway and Breathing must be addressed immediately.
Elevating the head of the bed maximizes chest expansion and provides immediate mechanical support for oxygenation.
3
Identify appropriate data collection and escalation protocols.
The PN must obtain full vital signs and escalate the situation to the RN.
The RN must perform an advanced assessment and collaborate with the healthcare provider for emergency medical interventions, while the PN assists by providing critical physiological data.
