A resident in a rehabilitation facility requires assistance with elimination. The resident underwent a right-sided total hip arthroplasty using a posterior surgical approach two days ago. When positioning this resident to use a fracture bedpan, which action by the practical nurse is most appropriate?

Show answer & explanation

Answer: Instruct the resident to use an overhead trapeze bar to lift the buttocks straight up while keeping the right leg slightly abducted.

Answer

The most appropriate action is to instruct the resident to use an overhead trapeze bar to lift the buttocks straight up while keeping the right leg slightly abducted.
For a posterior approach total hip arthroplasty, the hip must not be flexed beyond 90 degrees, and adduction or internal rotation must be completely avoided to prevent prosthesis dislocation. Using an overhead trapeze bar allows the client to lift their pelvis straight up without flexing the hip or rolling, while slight abduction maintains safe joint alignment for the placement of a fracture pan.

Step-by-Step Solution

1
Identify the specific surgical procedure and its associated precautions.
The client had a posterior total hip arthroplasty. Precautions include avoiding hip flexion greater than 90 degrees, avoiding adduction (crossing midline), and avoiding internal rotation.
Understanding the anatomical limitations post-surgery is essential to prevent prosthetic dislocation during routine basic care.
2
Evaluate the demands of placing a bedpan against the required post-operative precautions.
Using a bedpan normally requires lifting the pelvis or rolling the client, both of which can compromise hip alignment if performed incorrectly.
Basic care tasks must be adapted to fit within the safety parameters of the client's current physiological state.
3
Select the intervention that achieves the care goal without violating joint precautions.
Using an overhead trapeze bar with the leg abducted allows vertical lifting without dangerous flexion or adduction.
This action promotes client independence and comfort while strictly adhering to posterior hip precautions.

Key Concept

Maintenance of post-operative positioning precautions during basic care and comfort procedures.

An 82-year-old client who is recovering from a surgical repair of a fractured femur suddenly becomes agitated, confused, and has a respiratory rate of 28 breaths/minute. Which of the following actions should the practical nurse (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 level.; Elevate the head of the client's bed to maximize chest expansion.; Promptly notify the registered nurse (RN) about the acute changes in the client's condition.

Answer

The correct actions include elevating the head of the bed, applying a pulse oximeter, and immediately notifying the registered nurse (RN).
The client's sudden onset of agitation, confusion, and tachypnea are early, critical signs of hypoxia or a potential fat embolism syndrome, a known complication of long bone fractures. The appropriate nursing response is to prioritize Airway and Breathing by elevating the head of the bed to facilitate lung expansion, applying a pulse oximeter to gather objective oxygenation data, and immediately notifying the RN to escalate care. These actions directly address the potential life-threatening physiological adaptation failure.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has sudden confusion, agitation, and a respiratory rate of 28 breaths/minute following a femur fracture repair.
Identifying the onset and nature of symptoms is necessary to determine the level of urgency.
2
Apply the Airway, Breathing, and Circulation (ABC) prioritization framework.
Tachypnea and sudden confusion indicate a high probability of compromised breathing and oxygenation (e.g., hypoxia or fat embolism).
The ABC framework dictates that respiratory compromise must be addressed before pain management or routine care.
3
Select the immediate nursing interventions that support the ABCs and client safety.
Elevating the head of the bed improves breathing mechanics, applying a pulse oximeter provides objective oxygenation data, and notifying the RN ensures rapid escalation of care.
These actions are within the PN scope of practice and directly address the life-threatening potential of the client's symptoms.

Question 1223Question →

A practical nurse is preparing to administer a combined dose of regular insulin and NPH insulin in a single syringe to a client with diabetes mellitus. Arrange the following steps for preparing this medication in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
When mixing regular (clear) and NPH (cloudy) insulin, the standard safety protocol is 'clear before cloudy'. This prevents the intermediate-acting NPH insulin from contaminating the short-acting regular insulin vial. The sequence of injecting air into the NPH first, then air into the regular, ensures that the needle does not carry regular insulin into the NPH vial during air injection, and prepares the vials for safe withdrawal.

Step-by-Step Solution

1
Roll the NPH insulin vial between the palms.
The cloudy suspension is mixed without creating air bubbles.
Ensures the insulin is evenly distributed before drawing the dose.
2
Inject air into the NPH insulin vial.
Pressure is equalized in the NPH vial.
Prevents a vacuum from forming when fluid is later withdrawn.
3
Inject air into the regular insulin vial.
Pressure is equalized in the regular insulin vial.
Prepares the vial for immediate withdrawal of the clear insulin.
4
Withdraw the regular insulin.
The clear insulin is drawn into the syringe first.
Prevents accidental contamination of the rapid/short-acting insulin with longer-acting insulin.
5
Withdraw the NPH insulin.
The combined dose is now completely drawn into the syringe.
The cloudy insulin is drawn last to complete the mixture safely without pushing regular insulin into the NPH vial.

A practical nurse is caring for a client who is receiving continuous nasogastric (NG) tube suctioning for a mechanical bowel obstruction. During morning rounds, the client reports severe leg cramps and a fluttering sensation in the chest. The nurse assesses a blood pressure of 108/62108/62 mm Hg and an irregular heart rate of 112112 beats per minute. The most recent basic metabolic panel reveals a serum potassium level of 2.82.8 mEq/L (2.82.8 mmol/L). Which of the following actions should the nurse take first?

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the client's assessment findings and laboratory results.

Answer

The correct action is to notify the registered nurse immediately regarding the client's assessment findings and laboratory results.
Continuous nasogastric suctioning places the client at significant risk for electrolyte depletion, particularly hypokalemia. A serum potassium level of 2.82.8 mEq/L is critically low (normal range is 3.53.5 to 5.05.0 mEq/L). The presence of severe leg cramps, palpitations, and an irregular heart rate indicates symptomatic hypokalemia, which can rapidly progress to life-threatening cardiac dysrhythmias. Recognizing these risk factors and immediately escalating the critical findings to the registered nurse is the priority action for the practical nurse to ensure prompt medical intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation and laboratory data.
The client has a critically low serum potassium level (2.82.8 mEq/L) and is exhibiting signs of symptomatic hypokalemia, including muscle cramps, palpitations, and an irregular heart rate.
Continuous nasogastric suction removes potassium-rich gastric secretions, placing the client at high risk for electrolyte imbalances.
2
Determine the priority nursing action based on the practical nurse scope of practice.
The practical nurse must immediately escalate these critical findings to the registered nurse.
Symptomatic hypokalemia can lead to life-threatening cardiac dysrhythmias and requires prompt medical intervention (such as intravenous potassium replacement) which is outside the independent scope of the practical nurse.

A practical nurse is providing morning hygiene for an adult uncircumcised male client who has an indwelling urinary catheter. In what order should the nurse perform the following steps of perineal care? Arrange the actions in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with preparation and exposure, followed by cleansing from the cleanest area (meatus) to dirtier areas (catheter tubing, then scrotum), and concludes with replacing the foreskin to prevent injury.
Performing perineal care with an indwelling catheter relies on strict adherence to the principles of medical asepsis. The nurse must clean from the least contaminated area (the urethral meatus) to the most contaminated areas (the surrounding skin). Proper sequence requires initial preparation, exposure of the meatus, cleansing of the meatus, cleansing down the catheter (wiping away from the body), and then washing the surrounding tissue. Finally, replacing the foreskin is an absolute safety requirement to prevent paraphimosis.

Step-by-Step Solution

1
Don gloves and place a waterproof pad.
The environment and nurse are prepared for the procedure.
Standard precautions and bed protection are foundational first steps.
2
Retract the foreskin.
The urethral meatus is fully exposed.
Exposure is necessary to properly clean the anatomical site most at risk for infection.
3
Cleanse the meatus and glans.
The cleanest and most vulnerable area is sanitized.
Medical asepsis requires cleaning from the least contaminated (meatus) to the most contaminated area.
4
Wipe down the catheter tubing away from the meatus.
The proximal section of the catheter is cleaned.
Wiping away from the meatus prevents the mechanical introduction of microorganisms into the urethra (CAUTI prevention).
5
Wash the penile shaft and scrotum.
The surrounding perineal areas are cleansed.
These areas are considered more contaminated than the meatus and are washed last in the genital region.
6
Return the foreskin to its natural position.
The glans is covered and circulation remains uncompromised.
Failure to replace the foreskin can result in paraphimosis, causing severe edema and tissue damage.

Hemoglobin11.2 g/dL11.2\text{ g/dL}

Which of the following actions is the most appropriate for the practical nurse to take?

Show answer & explanation

Answer: Withhold both the heparin and the metoprolol, and immediately report the findings to the registered nurse.

Answer

The most appropriate action is to withhold both the heparin and the metoprolol, and immediately report the assessment findings to the registered nurse.
The correct action is to withhold both medications and notify the registered nurse. The client's blood pressure of 98/58 mm Hg98/58\text{ mm Hg} is borderline hypotensive, which warrants withholding the beta-blocker (metoprolol) to prevent further cardiovascular depression. Furthermore, the platelet count of 75,000/mm375,000/\text{mm}^3 indicates significant thrombocytopenia (normal is 150,000150,000 to 400,000/mm3400,000/\text{mm}^3), placing the client at a high risk for bleeding; therefore, the anticoagulant (heparin) must also be withheld pending further medical evaluation.

Step-by-Step Solution

1
Analyze the client's vital signs in relation to the prescribed metoprolol.
The blood pressure is borderline hypotensive at 98/58 mm Hg98/58\text{ mm Hg}.
Metoprolol is a beta-blocker that lowers both heart rate and blood pressure. It should typically be withheld if the systolic blood pressure is below 100 mm Hg100\text{ mm Hg} to prevent cardiovascular collapse.
2
Evaluate the laboratory results in relation to the prescribed heparin.
The platelet count is critically low at 75,000/mm375,000/\text{mm}^3 (thrombocytopenia).
A normal platelet count is 150,000150,000 to 400,000/mm3400,000/\text{mm}^3. Administering an anticoagulant to a client with significant thrombocytopenia drastically increases the risk of severe, life-threatening hemorrhage.
3
Determine the appropriate nursing intervention within the practical nurse scope of practice.
Both medications must be withheld and the findings immediately escalated to the registered nurse.
The practical nurse is responsible for recognizing abnormal pre-administration assessment data, preventing adverse drug events, and reporting critical findings to the supervising nurse or provider.

Question 1227Question →

An adult client is transferred to the surgical unit following a subtotal thyroidectomy. The client reports mild discomfort at the anterior neck incision site. Which positioning intervention is most appropriate for the practical nurse to implement to promote comfort and prevent complications?

Show answer & explanation

Answer: Maintain the bed in a semi-Fowler's position at 30 to 45 degrees while supporting the head and neck with pillows.

Answer

Maintain the bed in a semi-Fowler's position at 30 to 45 degrees while supporting the head and neck with pillows.
Placing the client in a semi-Fowler's position (30 to 45 degrees) uses gravity to help reduce edema in the head and neck, which is critical for protecting the airway after thyroid surgery. Simultaneously supporting the head and neck with pillows keeps the cervical spine in a neutral position, preventing tension on the surgical incision and minimizing pain.

Step-by-Step Solution

1
Analyze the surgical procedure and its anatomical location.
The client had a subtotal thyroidectomy, meaning an incision was made in the anterior neck.
Understanding the surgical site is necessary to anticipate potential complications such as airway compromise or bleeding.
2
Identify the primary goals for post-thyroidectomy positioning.
The goals are to maintain a patent airway, reduce tissue edema, and prevent tension or stretching on the neck suture line.
Proper positioning directly impacts the client's respiratory status and wound healing.
3
Evaluate the positioning options against the identified goals.
The semi-Fowler's position with head and neck support meets all criteria by decreasing swelling via gravity and keeping the neck in a neutral alignment.
This specific alignment prevents hyperextension and hyperflexion, both of which are dangerous post-thyroidectomy.

A practical nurse is preparing to administer clindamycin to a pediatric client who weighs 24.2 lb24.2\text{ lb}. The healthcare provider prescribes clindamycin 15 mg/kg/day15\text{ mg/kg/day} intramuscularly (IM) divided into equal doses every 8 hours8\text{ hours}. The medication is supplied in a vial labeled 300 mg/2 mL300\text{ mg}/2\text{ mL}. How many mL will the practical nurse administer per dose? (Record the answer to the nearest tenth. Do not include units in your answer.)

Show answer & explanation

Answer: 0.4

Answer

0.4
The correct dose is calculated by sequentially converting weight to kilograms, finding the total daily dose, dividing by the administration frequency, and calculating the volume using the provided medication concentration. The resulting 0.366... mL0.366...\text{ mL} rounds to 0.4 mL0.4\text{ mL}.

Step-by-Step Solution

1
Convert the client's weight from pounds to kilograms.
24.2÷2.2=11 kg24.2 \div 2.2 = 11\text{ kg}
The prescribed medication dosage is weight-based in kg, so the weight must be converted from pounds to kilograms.
2
Calculate the total daily dosage required.
11 kg×15 mg/kg=165 mg/day11\text{ kg} \times 15\text{ mg/kg} = 165\text{ mg/day}
Multiplying the client's weight in kg by the prescribed mg/kg/day provides the total amount of medication needed for 24 hours.
3
Determine the dose to be administered every 8 hours.
165 mg÷3=55 mg/dose165\text{ mg} \div 3 = 55\text{ mg/dose}
Medication ordered every 8 hours is given 3 times a day (24 / 8 = 3). Dividing the total daily dose by 3 gives the single dose amount.
4
Calculate the volume (mL) needed for the single dose.
55 mg×2 mL300 mg=0.3666... mL55\text{ mg} \times \frac{2\text{ mL}}{300\text{ mg}} = 0.3666...\text{ mL}
Using the formula (Desired / Have) x Volume, the needed dose is divided by the supplied concentration and multiplied by the supplied volume.
5
Round the final volume to the nearest tenth.
0.4 mL0.4\text{ mL}
Standard nursing administration and syringe measurement rules typically require rounding volumes less than 1 mL to the nearest hundredth or tenth depending on the syringe, but the prompt explicitly requested rounding to the nearest tenth.

A licensed practical nurse (LPN) is caring for an older adult client who is recovering from a major abdominal surgery. Which of the following actions by the nurse demonstrate an appropriate application of risk reduction principles? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Withholding a scheduled dose of furosemide and alerting the registered nurse about a serum potassium level of 2.8 mEq/L.; Promptly notifying the registered nurse when the client's heart rate increases to 115 beats per minute and blood pressure drops to 90/58 mm Hg.; Verifying the client's name and date of birth against the medical record prior to obtaining a blood specimen.

Answer

The correct actions include withholding furosemide for a critically low potassium level, reporting subtle but concerning changes in vital signs, and verifying two client identifiers prior to drawing blood.
The correct actions demonstrate proactive risk reduction. Severe hypokalemia (2.8 mEq/L) requires holding potassium-wasting diuretics and notifying the RN to prevent arrhythmias. Tachycardia combined with hypotension is an early sign of shock that requires immediate escalation. Finally, using two distinct identifiers before any procedure is a fundamental safety standard that reduces the risk of errors.

Step-by-Step Solution

1
Analyze each action to determine if it mitigates or increases the client's risk for postoperative complications.
Identify actions that promote safety and rapid intervention.
Reduction of risk potential requires the nurse to anticipate complications and act proactively.
2
Evaluate the laboratory values and vital signs presented in the options.
Recognize that a potassium of 2.8 mEq/L and hemoglobin of 6.7 g/dL are critical. Note that a rising heart rate with dropping blood pressure indicates potential shock.
Accurate interpretation of clinical data is necessary to determine when to escalate care.
3
Select the options that reflect safe, evidence-based nursing practice.
The correct choices involve escalating critical labs and vital signs, and performing proper client identification.
These actions directly align with the LPN's role in reducing risk potential.

Question 1230Question →

A practical nurse (PN) is caring for a client with a central venous catheter (CVC). Upon entering the room, the PN discovers that the intravenous tubing has accidentally disconnected from the CVC hub. The client is suddenly dyspneic, coughing, and appears cyanotic. Suspecting a central line air embolism, in what order should the PN implement the following actions? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first clamp the catheter, position the client in a left lateral Trendelenburg position, activate the rapid response system, administer oxygen, and finally obtain vital signs.
In a suspected central line air embolism, the absolute first step is source control: clamping the catheter to prevent further air entry. Second, the client must be placed in Durant's maneuver (left lateral decubitus with Trendelenburg) to trap the air bubble in the apex of the right ventricle, keeping it away from the pulmonary outflow tract. Third, the nurse must activate the rapid response system to mobilize advanced help. Fourth, administering 100% oxygen treats ischemia and helps reduce the size of the air embolus by promoting nitrogen washout. Finally, obtaining vital signs provides essential baseline data for the arriving emergency team.

Step-by-Step Solution

1
Clamp the exposed central venous catheter immediately.
Stops further air entry into the circulation.
Source control is the absolute top priority to prevent cardiovascular collapse.
2
Place the client on their left side with the head of the bed lowered.
Traps the air bubble in the right ventricle.
This specific position (Durant's maneuver) prevents the embolus from migrating to the pulmonary artery and causing a right ventricular outflow tract obstruction.
3
Activate the facility's rapid response system.
Summons the emergency medical team.
The client requires advanced interventions (e.g., provider aspiration of air) beyond the PN scope, making advanced support critical once immediate physical safeguards are in place.
4
Administer high-flow supplemental oxygen via a non-rebreather mask.
Promotes nitrogen washout and increases blood oxygenation.
High-flow oxygen decreases the size of the air bubble and treats the severe hypoxia caused by the embolism.
5
Obtain a complete set of vital signs and pulse oximetry.
Establishes a hemodynamic baseline.
Allows the arriving rapid response team to immediately assess the severity of shock and evaluate the client's response to the initial interventions.

Question 1231Question →

An older adult resident residing in an extended care facility is receiving intravenous antibiotic therapy for a severe soft tissue infection. The nursing assistant informs the practical nurse that the resident, who is usually alert and cooperative, is suddenly thrashing in bed and speaking incoherently. Upon evaluation, the nurse observes pale, diaphoretic skin with a heart rate of 118 beats per minute and a blood pressure of 92/54 mm Hg (baseline 136/80 mm Hg). Which intervention should the practical nurse implement immediately?

Show answer & explanation

Answer: Immediately alert the supervising nurse to the acute changes in the resident's condition.

Answer

The practical nurse must immediately alert the supervising nurse to the acute changes in the resident's condition.
The correct action is to immediately escalate the findings to the supervising nurse. The resident's sudden confusion, diaphoresis, tachycardia, and significant drop in blood pressure in the presence of an active infection are hallmark signs of septic shock. This is a life-threatening physiological adaptation that requires rapid medical intervention, which must be initiated and overseen by a registered nurse or healthcare provider.

Step-by-Step Solution

1
Analyze the resident's baseline data and current presentation.
The resident has a known infection and is suddenly confused, tachycardic (118 bpm), and hypotensive (92/54 mm Hg) compared to baseline.
Identifying acute deviations from baseline is essential for early recognition of life-threatening complications.
2
Correlate the clinical findings to potential pathophysiological processes.
The combination of a primary infection, new-onset altered mental status, increased heart rate, and decreased blood pressure strongly indicates early septic shock.
Septic shock causes systemic vasodilation, leading to hypotension and compensatory tachycardia, which subsequently decreases cerebral perfusion (causing confusion).
3
Determine the priority action within the practical nurse's scope of practice.
The highest priority is to escalate the findings to the supervising registered nurse or healthcare provider.
Septic shock is a medical emergency requiring urgent interventions outside the practical nursing scope, such as prescribing fluid boluses or ordering vasopressors.

A client who is recovering from abdominal surgery is preparing to move from the bed to a bedside chair for the first time. In what sequence should the nurse perform the following actions to ensure a safe transfer? Arrange the steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with preparing the environment (placing and locking the chair), followed by elevating the head of the bed, assisting the client to dangle their legs, monitoring for dizziness, and finally applying a transfer belt before standing.
Safe client mobilization requires a systematic approach. The nurse must first secure the environment by locking the chair in the optimal position. Next, the client is brought upright gradually by elevating the head of the bed and then pivoting to a dangling position. This gradual movement is crucial for post-operative clients to prevent orthostatic hypotension. The nurse must then verify the client's stability by checking for dizziness before applying the gait belt and initiating the weight-bearing phase of the transfer.

Step-by-Step Solution

1
Prepare the environment and equipment.
The destination chair is positioned correctly and secured.
Ensuring the chair is locked and appropriately angled guarantees a safe landing point and prevents the equipment from rolling during the transfer.
2
Raise the head of the bed.
The client is moved into an initial upright position.
Elevating the head minimizes physical exertion for the client and protects the abdominal incision from excess strain while transitioning.
3
Assist the client to a dangling position on the edge of the bed.
The client's legs are dependent, allowing the cardiovascular system to adjust.
Gradual position changes are essential in post-operative care to prevent a sudden drop in blood pressure.
4
Evaluate the client for orthostatic changes.
The nurse confirms the client is stable enough to stand.
Dizziness or syncope can lead to severe injury if the client is allowed to bear weight while hemodynamically unstable.
5
Apply a gait belt and assist with the stand-and-pivot maneuver.
The client is safely moved into the chair.
A transfer belt provides the nurse with a firm, safe hold on the client's center of gravity without pulling on their arms or shoulders.

Following a percutaneous liver biopsy, a client's electronic health record displays the following vital sign progression:

TimepointBlood Pressure (mm Hg)Apical Pulse (beats/min)
Pre-procedure128/7672
1 hour post-procedure116/7088
2 hours post-procedure (Current)102/64104

The client currently appears pale and states, "I feel a little dizzy when I turn my head." Which immediate action should the practical nurse take?

Show answer & explanation

Answer: Notify the registered nurse of the vital sign trends and client symptoms

Answer

The correct action is to notify the registered nurse of the vital sign trends and client symptoms.
The client's trending vital signs (decreasing blood pressure and increasing heart rate) combined with pallor and dizziness strongly indicate early hypovolemic shock, a potential and life-threatening complication of internal hemorrhage following a liver biopsy. The practical nurse must immediately escalate these critical findings to the registered nurse or healthcare provider to ensure rapid medical intervention.

Step-by-Step Solution

1
Analyze the vital sign trends over the two-hour post-procedure period.
Blood pressure dropped from 128/76 to 102/64 mm Hg, and the heart rate increased from 72 to 104 beats/min.
Comparing current data to baseline is essential to identify early physiological deterioration.
2
Correlate the vital sign changes with the client's physical symptoms and recent procedure.
The combination of tachycardia, relative hypotension, pallor, and dizziness after a highly vascular liver biopsy suggests internal bleeding.
Recognizing the systemic signs of hypovolemic shock allows for prompt escalation and risk reduction.
3
Determine the safest and most appropriate nursing intervention within the practical nurse scope.
The most critical action is to immediately notify the registered nurse or healthcare provider.
Suspected internal hemorrhage is a life-threatening emergency requiring advanced assessment and medical orders beyond the practical nurse's independent scope.

Question 1234Question →

An adult client is restricted to bed rest due to an acute deep venous thrombosis (DVT) in the right calf. The client reports dull, aching leg pain and requests a bed bath. When providing hygiene and comfort measures, which action by the practical nurse is the priority?

Show answer & explanation

Answer: Maintain the affected extremity supported on a soft wedge cushion above the level of the heart during the bathing process.

Answer

Maintain the affected extremity supported on a soft wedge cushion above the level of the heart during the bathing process.
Elevating the affected extremity above the level of the heart uses gravity to passively promote venous return. This safely reduces tissue edema and alleviates the client's aching discomfort without mechanically disturbing the acute thrombus. It is the gold standard for basic comfort and safety when caring for a client with a deep vein thrombosis.

Step-by-Step Solution

1
Identify the client's primary diagnosis and associated risks.
The client has an acute DVT in the right calf, presenting a severe risk for thrombus dislodgement and subsequent pulmonary embolism.
Understanding the underlying pathology is essential before performing any physical manipulation during hygiene care.
2
Evaluate the proposed hygiene and positioning interventions against safety contraindications.
Massaging the leg (firm upward strokes), applying popliteal pressure (blanket behind the knee), and performing active range-of-motion on the affected leg are identified as dangerous.
These actions increase mechanical pressure or muscle contraction around the vein, which can break the acute clot loose into the bloodstream.
3
Select the intervention that provides basic comfort and safety.
Elevating the leg on a wedge pillow is chosen as the safest and most effective action.
Elevation uses gravity to reduce venous congestion and localized pain without applying direct physical manipulation to the affected calf.

An older adult client with type 2 diabetes mellitus is scheduled to undergo a computed tomography (CT) scan of the abdomen with intravenous contrast in two hours. The practical nurse is reviewing the client's morning laboratory results, which reveal a serum creatinine level of 2.2 mg/dL2.2\ \text{mg/dL} (194 μmol/L194\ \mu\text{mol/L}) and a blood urea nitrogen (BUN) of 35 mg/dL35\ \text{mg/dL} (12.5 mmol/L12.5\ \text{mmol/L}). What is the priority action for the practical nurse?

Show answer & explanation

Answer: Report the abnormal renal function tests to the supervising registered nurse or provider immediately.

Answer

The priority action is to immediately report the abnormal renal function tests to the supervising registered nurse or provider.
The correct answer is to report the abnormal laboratory results. A serum creatinine of 2.2 mg/dL2.2\ \text{mg/dL} indicates significantly impaired renal function. Intravenous contrast is nephrotoxic and can cause permanent kidney damage if administered to a client with an already elevated creatinine level. The provider must be notified immediately so the procedure can be canceled, postponed, or performed without contrast.

Step-by-Step Solution

1
Identify the planned procedure and its associated risks.
The client is scheduled for a CT scan with intravenous contrast, which is known to be nephrotoxic.
Understanding the nature of the procedure is essential for identifying potential complications.
2
Analyze the provided laboratory data.
The serum creatinine (2.2 mg/dL2.2\ \text{mg/dL}) and BUN (35 mg/dL35\ \text{mg/dL}) are significantly elevated.
Elevated creatinine and BUN indicate impaired renal function or acute kidney injury.
3
Synthesize the data to determine the clinical risk.
Administering IV contrast to a client with existing renal impairment places them at high risk for contrast-induced nephropathy. Furthermore, the client takes metformin for diabetes, which increases the risk of lactic acidosis if given alongside contrast.
Connecting the client's underlying condition and laboratory values to the procedural risks guides safe nursing practice.
4
Select the appropriate nursing intervention within the practical nurse scope of practice.
The practical nurse must immediately notify the registered nurse or healthcare provider to halt the procedure and re-evaluate the plan of care.
Timely escalation of critical findings is a primary responsibility to prevent adverse client outcomes.

The PN notes the client is restless with pale, cool skin. The client's vital signs are: blood pressure 92/54 mm Hg, apical pulse 118 beats/minute, and respirations 22 breaths/minute. Which of the following actions should the PN take first?

Show answer & explanation

Answer: Withhold the hydrocodone-acetaminophen and immediately notify the registered nurse.

Answer

The practical nurse should withhold the hydrocodone-acetaminophen and immediately notify the registered nurse.
The client's clinical presentation (tachycardia, hypotension, restlessness, pale and cool skin) strongly suggests hypovolemic shock, a serious postoperative complication. Opioid analgesics like hydrocodone can cause vasodilation and further lower blood pressure. Therefore, administering the medication is unsafe. The practical nurse is acting correctly within their scope of practice by withholding the contraindicated medication and immediately reporting the critical change in condition to the registered nurse for advanced assessment and intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation and vital signs.
The client has a low blood pressure (92/54 mm Hg), elevated heart rate (118 beats/minute), elevated respiratory rate (22 breaths/minute), restlessness, and pale, cool skin.
Data collection is the first step in the nursing process to determine the client's current physiological status.
2
Interpret the clinical findings in the context of the postoperative period.
These findings are early signs of hypovolemia or hemorrhage, which is a life-threatening complication of an abdominal hysterectomy.
Recognizing signs of shock is critical for prioritizing care based on the Airway, Breathing, Circulation (ABC) framework.
3
Evaluate the safety of administering the prescribed medication.
Hydrocodone-acetaminophen is an opioid, which can cause vasodilation and further decrease blood pressure, making it contraindicated in this unstable state.
The nurse must ensure pharmacological therapies are safe to administer based on current client data.
4
Determine the appropriate action within the practical nurse scope of practice.
The nurse must withhold the unsafe medication and immediately communicate the critical findings to the registered nurse.
Practical nurses are responsible for withholding medications that pose a risk and reporting abnormal findings to the directing RN or provider.

Key Concept

Recognizing signs of hypovolemic shock and appropriately withholding contraindicated medications while escalating care within the practical nursing scope of practice.

A practical nurse is receiving a client who has just returned to the medical-surgical unit following a percutaneous liver biopsy. Which position should the nurse assist the client into immediately after the procedure?

Show answer & explanation

Answer: Right side-lying position with a small towel or pillow under the puncture site

Answer

The client should be placed in a right side-lying position with a small towel or pillow under the puncture site.
The correct position is on the right side because the liver is located on the right side of the body. Resting on the right side with a small towel or pillow under the puncture site applies direct, sustained pressure to the liver capsule, which is crucial for preventing post-procedure hemorrhage.

Step-by-Step Solution

1
Identify the procedure performed and its anatomical location.
The client had a percutaneous liver biopsy; the liver is located in the right upper quadrant of the abdomen.
Understanding the anatomical site is necessary to determine the appropriate post-procedure care.
2
Determine the primary risk associated with the procedure.
The liver is highly vascular, making hemorrhage the most significant immediate post-procedure complication.
Prioritizing interventions based on the highest risk guides safe positioning.
3
Select the position that mitigates the identified risk.
Positioning the client on the right side applies external pressure to the biopsy site, promoting hemostasis.
Mechanical pressure on the puncture site helps prevent bleeding.

Key Concept

Post-procedure positioning for hemostasis

A pediatric client arrives at the primary care clinic for a scheduled measles, mumps, and rubella (MMR) vaccine. During the initial data collection, the guardian reports that the child has been taking a prescribed high-dose oral corticosteroid for the past two weeks to treat a severe asthma exacerbation. Which action is the priority for the practical nurse?

Show answer & explanation

Answer: Withhold the vaccine and report the client's current medication therapy to the healthcare provider.

Answer

The correct action is to withhold the vaccine and report the client's current medication therapy to the healthcare provider.
The MMR vaccine is a live-attenuated virus vaccine. High-dose systemic corticosteroids cause immunosuppression, which is a strict contraindication for receiving live vaccines due to the risk of severe infection. The practical nurse must prioritize client safety by recognizing this contraindication, withholding the vaccine, and reporting the finding to the healthcare provider.

Step-by-Step Solution

1
Analyze the client's current medication therapy in relation to the scheduled procedure.
The client is taking a high-dose oral corticosteroid, which causes systemic immunosuppression.
Identifying current medications is essential to prevent adverse drug interactions or complications.
2
Determine the characteristics of the scheduled vaccine.
The MMR vaccine is a live-attenuated virus vaccine.
Live vaccines carry a risk of causing active infection if administered to a client with a weakened immune system.
3
Apply the practical nursing scope of practice to the clinical finding.
The practical nurse must recognize the contraindication, withhold the administration, and promptly notify the provider or registered nurse.
Ensuring client safety by withholding contraindicated medications and reporting significant clinical data is a critical responsibility.

Key Concept

Immunization contraindications and safe medication administration within the practical nurse's scope of practice.
Question 1239Question →

A practical nurse (PN) is monitoring a client who returned to the unit two hours ago following a cardiac catheterization via the right femoral artery. The client is resting quietly and denies any discomfort. The PN obtains the following vital signs: heart rate 116 beats/min, blood pressure 96/60 mm Hg, and respiratory rate 16 breaths/min. The client's pre-procedure blood pressure was 136/82 mm Hg. Which action should the PN take first?

Show answer & explanation

Answer: Examine the right groin insertion site and the linens beneath the client.

Answer

The practical nurse should first examine the right groin insertion site and the linens beneath the client for signs of bleeding.
Following a femoral cardiac catheterization, the sudden onset of tachycardia and a drop in blood pressure are early physiological indicators of hemorrhage (either external bleeding at the site or internal retroperitoneal bleeding). The practical nurse must immediately collect focused data by inspecting the insertion site and the linens underneath the client's back for pooling blood. This crucial information must be gathered before immediately escalating the findings to the registered nurse or healthcare provider.

Step-by-Step Solution

1
Analyze the client's current vital signs compared to baseline data.
The client has developed sudden tachycardia (116 beats/min) and mild hypotension (96/60 mm Hg from 136/82 mm Hg).
Recognizing subtle signs of hemodynamic instability is critical for early intervention.
2
Relate the clinical findings to the recent surgical procedure.
Cardiac catheterization via the femoral artery carries a high risk of external bleeding or internal retroperitoneal hemorrhage.
Understanding procedure-specific complications guides focused data collection.
3
Determine the priority nursing action within the practical nurse scope of practice.
The PN must immediately inspect the insertion site and surrounding area to identify the source of potential bleeding.
Identifying active bleeding is essential for prioritizing Circulation (ABC) before escalating the findings to the registered nurse.

Key Concept

Prioritizing data collection for hemorrhage post-cardiac catheterization

A practical nurse (PN) is caring for a client who is 3 days postoperative following a laparotomy. The client reports a "popping" sensation after a severe bout of coughing. Upon inspection, the PN observes that the surgical incision has opened and bowel loops are protruding. In which order should the PN perform the following actions? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for an abdominal evisceration is to first call for help and stay with the client, then position the client to reduce abdominal tension, next cover the protruding organs with sterile moistened dressings, and finally assess vital signs.
In the event of an evisceration, the primary goal is to protect the exposed organs and prepare for emergency surgery. The nurse must first ensure help is on the way because they cannot leave the client to gather supplies. Immediately positioning the client reduces intra-abdominal pressure to prevent further evisceration. Once the delegated staff brings the sterile supplies, the nurse covers the organs to prevent necrosis. Finally, vital signs are assessed to monitor for shock as the client is prepared for the operating room.

Step-by-Step Solution

1
Call for immediate assistance and remain with the client.
Help is mobilized without leaving the client unattended in an emergency.
Evisceration is a medical emergency requiring sterile supplies and immediate surgical intervention. The nurse must not leave the client alone.
2
Place the client in a low Fowler's position with the knees flexed.
Abdominal muscle tension is reduced.
This specific position relaxes the abdominal wall, which prevents further pushing out of the internal organs.
3
Cover the exposed organs with sterile dressings moistened with sterile 0.9% sodium chloride.
The eviscerated tissue is protected from drying and environmental contaminants.
Exposed bowel can quickly dry out and become necrotic. Sterile saline maintains tissue viability until surgical repair.
4
Assess the client's vital signs.
Baseline hemodynamic status is established.
The client is at high risk for hypovolemic shock due to fluid shifts, bleeding, and stress. Monitoring vitals guides further emergency interventions.

Key Concept

The priority management of an abdominal evisceration involves securing help, reducing abdominal tension, protecting the exposed tissue, and monitoring for shock.
