Question 1001Question →

A client with severe chronic obstructive pulmonary disease (COPD) and bilateral lower extremity edema is confined to bed rest 72 hours after undergoing surgical stabilization of a pelvic fracture. To promote optimal comfort, preserve skin integrity, and accommodate all underlying physiological needs, which positioning strategy should the practical nurse execute?

Show answer & explanation

Answer: Maintain a semi-Fowler's position and place soft pillows lengthwise under the calves to suspend the heels.

Answer

The correct approach is to maintain a semi-Fowler's position and place soft pillows lengthwise under the calves to suspend the heels.
Maintaining a semi-Fowler's position allows gravity to pull the diaphragm downward, maximizing lung expansion for the client with COPD. Placing pillows lengthwise under the calves promotes venous return to reduce dependent edema while simultaneously offloading pressure from the heels and avoiding popliteal vein compression. This holistic approach safely accommodates the pelvic fracture restrictions while providing optimal basic care.

Step-by-Step Solution

1
Analyze the respiratory requirements of the client.
The client has severe COPD, which requires the head of the bed to be elevated to facilitate lung expansion and ease the work of breathing.
Gravity pulls abdominal organs downward, allowing the diaphragm to fully contract during inspiration.
2
Evaluate the surgical restrictions related to the pelvic fracture.
Extreme hip flexion, weight-bearing, or unsupported dangling of the lower extremities must be avoided.
These actions place severe stress on the newly stabilized pelvic bones and hardware.
3
Address the circulatory and integumentary risks associated with edema and bed rest.
The lower extremities must be elevated to reduce edema, but without creating sharp bends behind the knees. The heels must also be protected from pressure.
Sharp knee gatching impedes venous return and increases deep vein thrombosis (DVT) risk. Floating the heels prevents decubitus ulcers.
4
Synthesize the findings to select the optimal position.
A semi-Fowler's position with lengthwise calf pillows safely meets respiratory, circulatory, and post-surgical requirements simultaneously.
It addresses all three competing physiological needs without violating any safety contraindications.

Question 1002Question →

A practical nurse is planning morning hygiene and comfort care for a client who is 1 day postoperative following a right-sided total hip arthroplasty (posterior approach). The client reports mild joint stiffness and requests assistance with a bed bath and repositioning. Which action should the nurse take?

Show answer & explanation

Answer: Place an abduction wedge between the client's legs and obtain assistance to turn the client onto the unaffected left side

Answer

Place an abduction wedge between the client's legs and obtain assistance to turn the client onto the unaffected left side.
Following a total hip arthroplasty with a posterior approach, the client is at high risk for hip dislocation. To prevent this, the nurse must maintain the affected leg in a neutral, abducted position and strictly avoid hip adduction, internal rotation, and flexion greater than 90 degrees. Placing an abduction wedge between the legs prevents adduction, and turning the client onto the unaffected (left) side while maintaining alignment is the safest way to provide back care and reposition the client for comfort.

Step-by-Step Solution

1
Analyze the client's surgical procedure.
The client had a right-sided total hip arthroplasty via a posterior approach.
Different surgical approaches have specific postoperative movement restrictions that dictate safe basic care.
2
Identify the positioning constraints for this procedure.
Posterior THA requires preventing hip flexion greater than 90 degrees, internal rotation, and adduction.
These specific movements can cause the newly placed prosthetic joint to dislocate posteriorly.
3
Evaluate the proposed nursing actions against surgical constraints and the LPN/VN scope of practice.
Using an abduction wedge and turning to the unoperated side maintains proper alignment. High-Fowler's position violates the flexion restriction. IVP medication administration violates the PN scope of practice.
Basic care must simultaneously align with safety protocols, therapeutic communication standards, and legal scope of practice.

Question 1003Question →

A client is recovering on the surgical unit following a right total hip arthroplasty utilizing a posterior approach. The practical nurse is preparing to turn the client to assess the sacral area. Which action represents the safest technique for this client?

Show answer & explanation

Answer: Keep an abduction wedge placed between the client's legs while rolling them onto their left side

Answer

Keep an abduction wedge placed between the client's legs while rolling them onto their left side.
For a client with a posterior approach total hip arthroplasty, the hip must remain in an abducted, neutral position to prevent prosthesis dislocation. Using an abduction wedge between the legs while turning the client onto the unaffected (left) side maintains this alignment and safely prevents the surgical hip from crossing the midline (adducting) or internally rotating.

Step-by-Step Solution

1
Identify the surgical procedure and the associated post-operative precautions.
The client had a right total hip arthroplasty (posterior approach).
Different surgical approaches have specific movement restrictions to prevent prosthesis dislocation.
2
Recall the specific mobility restrictions for a posterior approach total hip arthroplasty.
Precautions include avoiding hip flexion greater than 90 degrees, avoiding adduction (crossing the midline), and avoiding internal rotation of the affected leg.
These specific movements force the newly placed femoral head out of the acetabular cup.
3
Evaluate each nursing action against the identified safety precautions.
Using an abduction wedge prevents adduction. The other actions promote extreme flexion, internal rotation, or adduction.
Basic care must be performed without violating the prescribed positional limitations.
4
Select the action that safely facilitates basic care.
Turning the client onto the unaffected (left) side with an abduction wedge is the safest technique.
This maintains neutral alignment of the operative hip while allowing access to the sacral area.

A practical nurse (PN) enters the room of a client receiving total parenteral nutrition (TPN) and discovers that the central venous catheter tubing has accidentally disconnected from the hub. The client is suddenly gasping for air, clutching their chest, and appears cyanotic. In what order should the PN perform the following actions? Arrange the actions in the correct 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 clamp the catheter, then position the client on their left side with the head lowered, followed by administering oxygen, and finally collecting vital signs.
In the event of a central venous catheter disconnection leading to an air embolism, the PN must follow strict prioritized steps. The very first action is to clamp the catheter to stop further air from being drawn into the venous system by negative intrathoracic pressure. Second, the client must be placed in the left lateral Trendelenburg position; this uses gravity to trap the air in the right atrium or right ventricle, preventing it from blocking the pulmonary artery. Third, high-flow oxygen is administered to combat the resulting severe hypoxia and help wash out nitrogen from the air bubble. Finally, once these immediate life-saving actions are complete, the PN collects a full set of vital signs to provide crucial hemodynamic data to the rapid response team and healthcare provider.

Step-by-Step Solution

1
Clamp the open lumen of the central venous catheter.
Further air entry is immediately halted.
The direct cause of the emergency (an open line into the central venous system) must be eliminated before any other intervention to prevent a larger, more lethal air embolism.
2
Turn the client onto their left side with the head of the bed lowered.
The air bubble is physically trapped.
The left lateral Trendelenburg position utilizes gravity to keep the air bubble in the apex of the right ventricle or atrium, preventing it from traveling into the pulmonary artery and causing a right ventricular outflow tract obstruction.
3
Administer high-flow supplemental oxygen via a non-rebreather mask.
Tissue hypoxia is treated.
The air embolism causes severe ventilation/perfusion mismatch and hypoxia; high-flow oxygen helps reverse the hypoxemia and may assist in resorbing the nitrogen gas bubble.
4
Collect a complete set of vital signs to report to the rapid response team.
Baseline data is gathered for the arriving team.
Hemodynamic status must be evaluated after initial life-saving measures to report to the registered nurse and emergency providers.

Key Concept

Emergency management of a suspected central line air embolism prioritizes immediately stopping air entry, then utilizing positional gravity to trap the air, followed by oxygenation and hemodynamic monitoring.

Question 1005Question →

A practical nurse is monitoring a client who began receiving a packed red blood cell (PRBC) transfusion 15 minutes ago. The client suddenly reports severe lower back pain, acute chills, and a sensation of chest tightness. Arrange the following nursing actions in the correct sequence of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate cessation of the offending agent, followed by securing safety (new IV line), escalating care (notifying RN), collecting critical data (vital signs), and finally completing diagnostic protocols (returning blood, collecting urine).
The sequence follows the airway, breathing, circulation (ABC) and nursing process prioritization frameworks. Stopping the transfusion immediately removes the life-threatening trigger. Changing the tubing ensures the client receives necessary IV fluids without receiving the residual incompatible blood left in the old line. Notifying the RN brings advanced life support. Taking vital signs provides necessary data to the RN upon arrival. Returning the blood bag and collecting a urine sample are diagnostic and administrative tasks that must wait until the client is stabilized.

Step-by-Step Solution

1
Halt the transfusion
Prevents further administration of incompatible red blood cells.
The client is exhibiting classic signs of an acute hemolytic transfusion reaction (lower back pain, chills, dyspnea). Removing the offending agent is the primary life-saving action.
2
Maintain intravenous access with new tubing and normal saline
Keeps the vein open for emergency drugs without infusing residual blood.
Flushing the old tubing would push more incompatible blood into the client. New tubing ensures safety while maintaining a route for vascular support.
3
Alert the registered nurse and emergency response team
Initiates advanced medical support.
The client will require medications and interventions beyond the practical nurse's scope of practice to manage potential shock and acute renal failure.
4
Assess vital signs and cardiopulmonary status
Provides critical baseline data regarding the severity of the reaction.
This data guides the incoming rapid response team in diagnosing the extent of hemodynamic instability or respiratory compromise.
5
Secure the blood bag and tubing for the laboratory
Preserves evidence for blood bank analysis.
The laboratory must crossmatch the blood again to determine the exact cause and type of the hemolytic reaction.
6
Obtain a urine specimen
Provides a sample to test for hemoglobinuria.
Hemolyzed red blood cells release free hemoglobin, which is filtered by the kidneys and can cause acute tubular necrosis. This confirms the systemic impact.

Key Concept

Prioritization of care during an acute hemolytic transfusion reaction requires immediate cessation of the blood product, maintaining venous access with sterile equipment, and rapid escalation of care before proceeding with secondary assessments and diagnostics.
Question 1006Question →

A practical nurse is collecting data from a client who is 2 hours postoperative following an abdominal hysterectomy. The client's vital signs are: blood pressure 98/60 mm Hg, heart rate 114 beats per minute, respiratory rate 18 breaths per minute, and oxygen saturation 96% on room air. The client reports incisional pain as 6 on a 0 to 10 pain scale. Which action should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse about the vital signs immediately

Answer

Notify the registered nurse about the vital signs immediately
The correct action is to notify the registered nurse immediately because a heart rate of 114 beats per minute and a blood pressure of 98/60 mm Hg are early indicators of hypovolemic shock and potential internal hemorrhage following major surgery. Rapid escalation is essential for client safety.

Step-by-Step Solution

1
Analyze the client's vital signs against expected postoperative baselines.
The heart rate of 114 beats per minute and blood pressure of 98/60 mm Hg are abnormal.
Identifying deviations from normal values is required to recognize early complications.
2
Apply the Airway, Breathing, Circulation (ABC) prioritization framework.
The vital signs indicate a potential issue with circulation (hypovolemia or hemorrhage).
Circulatory compromise is life-threatening and takes priority over managing the client's pain.
3
Determine the appropriate scope of practice for the practical nurse in this scenario.
The practical nurse must immediately report these critical findings to the registered nurse for further assessment and intervention.
Practical nurses must escalate sudden signs of instability to the RN or provider for advanced clinical judgment.

Key Concept

Question 1007Question →

A 78-year-old client is admitted to the medical unit with a history of melena and fatigue. While collecting vital signs, the practical nurse notes a resting heart rate of 112 beats per minute, a blood pressure of 96/62 mm Hg, and acute disorientation to the current location. Which of the following actions should the nurse implement? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the change in status.; Ensure the patency of the client's peripheral intravenous access.; Apply supplemental oxygen per the facility's standing emergency protocol.

Answer

The nurse should immediately notify the registered nurse, ensure the patency of the intravenous access, and apply supplemental oxygen.
The client is demonstrating classic signs of compensatory hypovolemic shock and resulting cerebral hypoxia, indicated by tachycardia, borderline low blood pressure, and acute confusion. The practical nurse must prioritize circulation and oxygenation by securing intravenous access, providing supplemental oxygen, and immediately escalating the situation to the registered nurse for advanced intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The combination of tachycardia, borderline low blood pressure, and acute confusion in a client with melena indicates early hypovolemic shock and hypoxia.
Recognizing physiological deterioration is the first step in prioritizing appropriate nursing care.
2
Prioritize interventions based on the ABCs (Airway, Breathing, Circulation).
Applying supplemental oxygen addresses breathing, while securing IV access and notifying the RN addresses circulation and necessary medical escalation.
Life-threatening physiological issues must be managed before routine or secondary tasks.
3
Identify inappropriate actions that would delay care.
Withholding notification for a lower blood pressure, assuming confusion is age-related, and prioritizing oral pain medication must be avoided.
These actions dangerously misinterpret subtle signs of shock and ignore immediate ABC priorities.

Question 1008Question →

An older adult client with a history of heart failure is prescribed a daily dose of oral furosemide. The most recent comprehensive metabolic panel reveals a serum potassium level of 2.62.6 mEq/L (2.62.6 mmol/L). Which action should the practical nurse take?

Show answer & explanation

Answer: Withhold the furosemide and immediately report the potassium level to the supervising registered nurse.

Answer

The nurse must withhold the diuretic medication and immediately notify the supervising registered nurse about the critically low potassium level.
The normal serum potassium level is 3.53.5 to 5.05.0 mEq/L (3.53.5 to 5.05.0 mmol/L). A level of 2.62.6 mEq/L (2.62.6 mmol/L) indicates severe hypokalemia. Furosemide is a potassium-wasting loop diuretic. Administering it would further lower the potassium level, placing the client at high risk for lethal cardiac dysrhythmias. The practical nurse must prioritize client safety by withholding the dose and escalating the critical finding immediately.

Step-by-Step Solution

1
Interpret the serum potassium laboratory result.
The value of 2.62.6 mEq/L is significantly below the normal adult range of 3.53.5 to 5.05.0 mEq/L, indicating severe hypokalemia.
Recognizing abnormal laboratory values is the first essential step in clinical risk reduction.
2
Analyze the relationship between the prescribed medication and the critical laboratory value.
Furosemide is a loop diuretic that causes the kidneys to excrete potassium. Giving this medication will worsen the client's already severe hypokalemia.
Understanding medication mechanism of action prevents the administration of contraindicated drugs.
3
Determine the safest nursing intervention within the practical nurse scope of practice.
The safest action is to withhold the dose and escalate the critical finding to the registered nurse or healthcare provider.
The practical nurse must act promptly to prevent harm and communicate critical data to the supervising team.

Question 1009Question →

A client diagnosed with bipolar disorder has been managed on a daily maintenance dose of oral lithium. Three days ago, the healthcare provider prescribed oral hydrochlorothiazide for newly diagnosed hypertension. During the morning assessment, the practical nurse notes the client is experiencing vomiting, profound muscle weakness, and new-onset coarse hand tremors. The client's morning serum sodium level is 128 mEq/L128\text{ mEq/L} (128 mmol/L128\text{ mmol/L}). Which action should the practical nurse take first?

Show answer & explanation

Answer: Withhold the morning doses of both lithium and hydrochlorothiazide and immediately notify the registered nurse.

Answer

The priority action is to withhold the morning doses of both lithium and hydrochlorothiazide and immediately notify the registered nurse.
The correct answer synthesizes three critical clinical points: the drug-drug interaction between lithium and thiazide diuretics, the interpretation of a critically low sodium level (128 mEq/L128\text{ mEq/L}), and the recognition of advanced lithium toxicity symptoms (coarse tremors, vomiting, profound weakness). Thiazide diuretics cause sodium depletion. Because lithium has a similar chemical structure to sodium, the kidneys compensate for hyponatremia by reabsorbing lithium, rapidly leading to toxicity. The safest and most appropriate action within the practical nursing scope of practice is to withhold both the diuretic and the lithium, and immediately escalate the situation to the registered nurse.

Step-by-Step Solution

1
Analyze the client's medication regimen and recent additions.
The client is taking lithium (a mood stabilizer) and was recently started on hydrochlorothiazide (a thiazide diuretic).
Identifying drug classes helps predict potential adverse interactions.
2
Evaluate the morning laboratory results.
The serum sodium level is 128 mEq/L128\text{ mEq/L}, which indicates severe hyponatremia (normal range is typically 135135 to 145 mEq/L145\text{ mEq/L}).
Thiazide diuretics promote the excretion of sodium and water, directly causing this low sodium level.
3
Correlate the client's physical symptoms with the physiological effects of the medications.
Because lithium is a salt, the kidneys will reabsorb lithium in the presence of low sodium. This leads to lithium accumulation and toxicity, manifesting as vomiting, profound weakness, and coarse hand tremors.
Recognizing the connection between hyponatremia and lithium toxicity is critical for prioritizing care.
4
Determine the safest priority action within the practical nurse's scope of practice.
The nurse must withhold the interacting medications to prevent further harm and urgently report the critical lab values and toxic symptoms to the registered nurse.
LPNs/LVNs must monitor for adverse effects, ensure medication safety, and escalate acute deteriorations to the RN or provider.

Question 1010Question →

A practical nurse is caring for a client who has just returned to the surgical unit following a total thyroidectomy. To promote comfort and prevent complications, which of the following positions should the nurse assist the client into?

Show answer & explanation

Answer: Semi-Fowler's position with pillows supporting the head and neck

Answer

The correct answer is the semi-Fowler's position with pillows supporting the head and neck.
Placing the client in a semi-Fowler's position uses gravity to help reduce swelling and edema in the neck area, which is critical for protecting the airway after a thyroidectomy. Supporting the head and neck with pillows prevents hyperextension, reducing tension on the surgical incision and promoting comfort.

Step-by-Step Solution

1
Analyze the surgical procedure and potential physiological complications.
A thyroidectomy involves an incision in the neck. Post-operative tissue edema or bleeding in this area can quickly compromise the client's airway.
Airway patency is the highest priority following head and neck surgery.
2
Identify the effects of different bed positions on the neck.
Elevating the head of the bed decreases fluid accumulation (edema) in the neck. Supporting the head reduces tension on the surgical sutures.
Proper positioning uses gravity to minimize swelling and maintains anatomical alignment to promote wound healing.
3
Select the safest and most comfortable position for the client.
The semi-Fowler's position with dedicated head and neck support is the most appropriate choice.
This directly prevents airway compromise and incision rupture.

A practical nurse (PN) is monitoring a client who is receiving a packed red blood cell (PRBC) transfusion. Fifteen minutes into the infusion, the client suddenly reports severe lower back pain, chills, and difficulty breathing. 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 is to first stop the blood transfusion immediately, followed by initiating a normal saline infusion using new IV tubing. Next, the PN must notify the RN and healthcare provider, and finally, obtain a complete set of vital signs.
In any acute transfusion reaction, the primary goal is to limit the client's exposure to the offending antigen. Therefore, stopping the transfusion is the immediate first step. Venous access must be maintained to administer emergency drugs, but it must be done with entirely new tubing to prevent infusing residual blood. Once the immediate danger is halted and the line is secured, the PN must escalate the situation by notifying the RN and provider. Finally, obtaining vital signs provides essential data for the provider to direct further care.

Step-by-Step Solution

1
Stop the blood transfusion.
Prevents additional incompatible blood cells from entering the systemic circulation.
Lower back pain, chills, and dyspnea are classic signs of an acute hemolytic transfusion reaction, which is a life-threatening emergency requiring immediate cessation of the causative agent.
2
Disconnect the blood tubing and start normal saline with new tubing.
Maintains patent venous access for emergency medications while preventing further exposure.
Flushing the existing tubing would push the remaining incompatible blood into the client. New tubing must be attached directly to the IV catheter hub.
3
Notify the RN and healthcare provider.
Escalates the clinical emergency to the appropriate personnel.
The client will require immediate medical intervention, emergency medications, and activation of the facility's blood bank reaction protocol.
4
Obtain vital signs and monitor.
Provides objective baseline data regarding the client's hemodynamic and respiratory stability.
Continuous monitoring is required to assess the severity of the reaction and guide ongoing emergency treatment.

Question 1012Question →

A practical nurse is preparing to administer a scheduled dose of oral warfarin to a client diagnosed with atrial fibrillation. Which of the following actions must the nurse take before administering this medication?

Show answer & explanation

Answer: Review the client's most recent international normalized ratio (INR).

Answer

Review the client's most recent international normalized ratio (INR).
Warfarin is an oral anticoagulant, and its therapeutic effect is directly measured by the prothrombin time (PT) and international normalized ratio (INR). Before administering warfarin, the nurse must review the most recent INR to ensure it is within the prescribed therapeutic range. Administering the medication without verifying this lab value places the client at a high risk for severe bleeding if the level is too high, or at risk for clotting if the level is subtherapeutic.

Step-by-Step Solution

1
Identify the medication class and its primary function.
Warfarin is recognized as an oral anticoagulant used to prevent blood clots.
Understanding the drug class is the first step in identifying its specific monitoring parameters.
2
Determine the specific laboratory value used to monitor this medication.
The therapeutic effect of warfarin is monitored using the international normalized ratio (INR).
Anticoagulants have a narrow therapeutic index and require strict lab monitoring to prevent hemorrhage or clotting.
3
Select the appropriate pre-administration safety check.
The nurse must check the most recent INR results before giving the dose.
If the INR is supra-therapeutic (too high), the dose must be withheld and reported to the RN or provider to prevent severe bleeding.

During evening rounds, an older adult client receiving intravenous antibiotics for community-acquired pneumonia suddenly appears restless, mutters incoherently, and repeatedly attempts to pull out their peripheral catheter. The client's skin is pale and slightly clammy. Vital signs display a heart rate of 116 bpm, a respiratory rate of 24/min, and a blood pressure of 100/74 mm Hg, whereas the baseline blood pressure from the previous shift was 136/82 mm Hg. The urinary drainage bag contains 65 mL of concentrated urine representing the past 4 hours of output. Which action should the practical nurse implement first?

Show answer & explanation

Answer: Immediately escalate the clinical findings to the supervising registered nurse for rapid intervention.

Answer

The correct action is to immediately escalate the clinical findings to the supervising registered nurse for rapid intervention.
The correct answer identifies that the client is exhibiting a dangerous triad of symptoms: a significantly narrowed pulse pressure with tachycardia (indicative of decreased cardiac output and sympathetic nervous system activation), severe oliguria (decreased renal perfusion), and acute restlessness (cerebral hypoxia). Recognizing these subtle, borderline systemic signs of physiological failure requires immediate escalation to the registered nurse or rapid response team, as it exceeds the practical nursing scope to independently manage hemodynamically unstable clients.

Step-by-Step Solution

1
Analyze the client's vital signs and physical assessment findings in combination.
The client has a narrowed pulse pressure (100/74 = 26 mm Hg difference), tachycardia (116 bpm), tachypnea (24/min), pale/clammy skin, and severe oliguria (65 mL over 4 hours = 16.25 mL/hr).
Identifying subtle deviations from baseline is critical for recognizing early physiological failure before cardiovascular collapse occurs.
2
Evaluate the new-onset restlessness and incoherent muttering.
Combined with the hemodynamic changes, this altered mental status indicates cerebral hypoxia and hypoperfusion, not simple confusion or dementia.
Restlessness is often the earliest behavioral sign of impaired oxygenation and compromised cardiac output.
3
Determine the priority intervention within the practical nursing scope of practice.
The client is in early compensatory shock (likely septic shock) and requires immediate advanced critical care interventions.
Managing hemodynamically unstable clients exceeds the practical nurse scope; recognizing the emergency and immediately escalating to the registered nurse or rapid response team is the most critical priority.

A practical nurse is preparing to transfer a client who has right-sided hemiparesis from the bed to a wheelchair. In what order should the nurse perform the following actions? Arrange the steps in the correct sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first position the wheelchair on the client's strong (left) side, then lock all wheels, assist the client to sit on the edge of the bed, apply the transfer belt, instruct the client to reach for the armrest with their strong hand, and finally pivot the client into the chair.
Safe client handling for a client with unilateral weakness (hemiparesis) requires leveraging their functional abilities while minimizing fall risks. Positioning the chair on the unaffected side (left) is the critical first step because it ensures the client will pivot on their strong leg. Locking the wheels is a mandatory safety prerequisite before initiating any movement. Bringing the client to a seated position allows for cardiovascular accommodation and provides access to properly apply the gait belt around the waist. Finally, directing the client to reach with their strong arm stabilizes their descent into the chair as the nurse physically assists the pivot.

Step-by-Step Solution

1
Place the equipment on the client's strong side.
The wheelchair is positioned on the left side at a 45-degree angle.
Maximizes the use of the client's unaffected side for weight-bearing during the pivot.
2
Lock the wheels on all equipment.
The bed and wheelchair are immobilized.
Prevents the equipment from rolling away, which is a primary cause of transfer-related falls.
3
Bring the client to a sitting position.
The client is sitting at the edge of the bed with feet flat on the floor.
Allows the cardiovascular system to adjust, preventing dizziness, and establishes a stable base of support.
4
Apply the transfer belt.
The belt is secured securely around the client's waist.
Provides the nurse with a safe, ergonomic hold on the client's center of gravity without pulling on their arms.
5
Guide the client's movement.
The client reaches for the wheelchair armrest with their left (unaffected) hand.
Uses the strong arm to stabilize the body and guide the hips into the center of the seat.
6
Execute the pivot transfer.
The client is successfully seated in the wheelchair.
Completes the transfer by utilizing the strength of the unaffected leg to bear the body's weight.

Answer

First, lock the wheels on the bed and wheelchair. Second, assist the client to sit on the edge of the bed. Third, place the transfer belt. Fourth, assist the client to stand and pivot. Finally, have the client grasp the armrests while sitting down.
Safe transfer protocols require establishing a stable environment first by locking all wheels. Next, physiological safety is ensured by allowing the client to adjust to sitting. Then, physical safety devices like a transfer belt are applied. Only after these preparations should the physical movement (standing and pivoting) occur, ending with a controlled descent using the armrests.

Step-by-Step Solution

1
Secure all equipment by locking the wheels.
The bed and wheelchair are completely stationary.
Prevents accidental movement that could lead to a fall during the transfer.
2
Help the client sit up on the side of the bed.
The client is dangling their legs over the edge of the mattress.
Allows the cardiovascular system to adjust to the upright position, reducing the risk of dizziness.
3
Apply the transfer belt around the client's waist.
The care provider has a safe, secure handhold on the client.
Provides mechanical advantage and prevents injury to both the client and the provider during the physical lift.
4
Assist the client to stand up and pivot.
The client is standing and aligned with the wheelchair.
Moves the client's center of gravity from the bed to the chair in a controlled motion.
5
Guide the client to reach for the armrests and sit.
The client is safely seated in the wheelchair.
Reaching for the armrests provides stability and allows for a controlled descent into the chair.

A practical nurse is preparing to administer a large-volume cleansing enema to an adult client experiencing severe constipation. Arrange the following procedural steps in the correct sequential order to ensure client safety, procedure effectiveness, and comfort.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first position the client in the left lateral Sims position, lubricate the tubing tip, insert the tubing 3 to 4 inches toward the umbilicus, elevate the container 12 to 18 inches while opening the clamp, and finally, lower the container if severe cramping occurs.
Administering an enema safely requires a highly specific sequence encompassing anatomical positioning, preparation, careful insertion, controlled instillation, and complication management. The client must first be in the left lateral Sims position to allow gravity to assist fluid flow into the descending and sigmoid colon. The tubing tip must then be lubricated to ensure atraumatic insertion. Next, the tube is safely inserted 3 to 4 inches, following the anatomical direction of the umbilicus. Once the tube is secured in the rectum, the fluid is instilled by elevating the bag 12 to 18 inches to provide safe hydrostatic pressure. Finally, the nurse continuously evaluates the client's tolerance, lowering the bag immediately if rapid distention causes severe cramping.

Step-by-Step Solution

1
Position the client.
Client is in the left lateral Sims position.
Follows the natural curvature of the descending and sigmoid colon, using gravity to assist fluid flow.
2
Lubricate the tubing.
The distal tip is fully coated with a water-soluble lubricant.
Prevents tissue trauma and sphincter spasm during the invasive insertion.
3
Insert the tubing.
The tube is placed safely 3 to 4 inches into the rectum.
Bypasses the internal sphincter securely when aimed forward toward the umbilicus.
4
Administer the solution.
Fluid flows into the bowel at a safe hydrostatic pressure.
Holding the bag strictly 12 to 18 inches high prevents excessively rapid bowel distention.
5
Monitor for complications.
The flow rate is immediately decreased by lowering the bag if cramping occurs.
Allows the bowel musculature to relax without having to completely abandon and restart the procedure prematurely.

A resident in a rehabilitation facility is recovering from a left above-knee amputation performed 48 hours ago. The individual expresses feelings of stiffness and aching in the remaining hip. What is the most appropriate positioning strategy the practical nurse should utilize to optimize comfort and preserve joint mobility?

Show answer & explanation

Answer: Assist the client into a prone position for 20 to 30 minutes several times a day.

Answer

The most appropriate strategy is to assist the client into a prone position for 20 to 30 minutes several times a day.
Prone positioning for 20 to 30 minutes, three to four times a day, is a critical nursing intervention for clients recovering from an above-knee amputation. This position actively extends the hip joint, stretching the flexor muscles and preventing the development of hip flexion contractures. Preventing these contractures is essential for the client's future ability to walk and properly fit a prosthesis.

Step-by-Step Solution

1
Analyze the client's postoperative timeframe (48 hours post-amputation) and identify the specific physiological risks associated with this recovery phase.
The initial 24-hour period for edema management has passed, making the prevention of hip flexion contractures the primary mobility priority.
Contractures can severely impair future mobility and prevent successful prosthetic fitting.
2
Evaluate the physiological effects of each positioning option on the hip joint.
Elevation on pillows, high-Fowler's positioning, and prolonged sitting all place the hip joint into a flexed position.
Maintaining the hip in prolonged flexion causes the muscles and ligaments to shorten, leading to contractures.
3
Select the intervention that actively counteracts hip flexion while promoting comfort.
Prone positioning is identified as the correct intervention.
Lying prone forces the hip into extension, stretching the flexor muscles and preserving joint mobility.

A client admitted with an exacerbation of heart failure is scheduled to receive oral furosemide and oral metoprolol. Prior to administration, the practical nurse obtains the following data: blood pressure 88/54 mm Hg, heart rate 116 beats/min, respiratory rate 22 breaths/min, and a morning serum potassium level of 3.1 mEq/L (3.1 mmol/L). Which action is the most appropriate for the practical nurse to take?

Show answer & explanation

Answer: Withhold both medications and promptly report the vital signs and laboratory findings to the registered nurse.

Answer

The most appropriate action is to withhold both the furosemide and the metoprolol, and immediately report the client's vital signs and potassium level to the registered nurse.
The client's hypotension (88/54 mm Hg) and compensatory tachycardia (116 beats/min) strongly suggest hypovolemia or decreased cardiac output. Metoprolol (a beta-blocker) will further decrease blood pressure, and furosemide (a loop diuretic) will exacerbate both the volume depletion and the existing hypokalemia (3.1 mEq/L). The safe and correct action is to withhold these medications and immediately escalate these critical findings to the registered nurse.

Step-by-Step Solution

1
Analyze the client's vital signs.
The blood pressure of 88/54 mm Hg is hypotensive, and the heart rate of 116 beats/min is tachycardic, suggesting potential hypovolemia or inadequate cardiac output.
Vital signs must be evaluated against standard parameters prior to administering cardiac or antihypertensive medications.
2
Analyze the laboratory data.
The serum potassium level is 3.1 mEq/L, which indicates significant hypokalemia (normal is typically 3.5 to 5.0 mEq/L).
Diuretics actively alter electrolyte balances, making baseline lab checks mandatory.
3
Evaluate the mechanism and adverse effects of the scheduled medications.
Furosemide is a potassium-wasting loop diuretic that will worsen the hypokalemia and hypovolemia/hypotension. Metoprolol is a beta-blocker that will further lower the blood pressure.
Understanding pharmacodynamics prevents administering medications that could cause patient harm.
4
Determine the correct nursing intervention within the practical nurse scope of practice.
The practical nurse must withhold the contraindicated medications and escalate the critical findings to the registered nurse for immediate medical intervention.
Advocating for patient safety requires recognizing adverse trends and communicating effectively with the supervising nurse.

Question 1019Question →

A client recovering from severe pneumonia is receiving intravenous antibiotics and continuous supplemental oxygen. The practical nurse enters the room to find the previously oriented client highly agitated, struggling to sit up, and picking aimlessly at the bed linens. Which action should the practical nurse take initially?

Show answer & explanation

Answer: Obtain the client's oxygen saturation level and count the respiratory rate.

Answer

The nurse should prioritize obtaining the client's oxygen saturation level and counting the respiratory rate.
In a client with a respiratory infection, sudden restlessness, agitation, and acute confusion are classic early signs of hypoxia. Using the nursing process and prioritizing Airway, Breathing, and Circulation (ABCs), the practical nurse must first collect objective data regarding the client's respiratory status before implementing any other interventions. Treating the symptoms without investigating the cause could lead to severe physiological deterioration.

Step-by-Step Solution

1
Identify the client's sudden change in condition.
The client is exhibiting acute agitation, restlessness, and confusion.
Recognizing a change from baseline is the first step in the clinical judgment process.
2
Correlate the behavioral changes with the client's underlying diagnosis.
The client has severe pneumonia, making them highly susceptible to impaired gas exchange and hypoxia.
Restlessness and acute confusion are classic early neurological signs of inadequate oxygenation to the brain.
3
Determine the priority nursing action using the ABCs (Airway, Breathing, Circulation) framework.
The nurse must obtain objective data regarding the client's respiratory status (oxygen saturation and respiratory rate).
Before implementing any interventions such as medications or restraints, the nurse must assess the most life-threatening potential cause of the behavioral change.

Key Concept

Recognizing early signs of hypoxia (restlessness and confusion) and prioritizing objective respiratory data collection.
Question 1020Question →

An assistive personnel (AP) calls the practical nurse to the room of an 84-year-old client who had a bowel resection two days ago. The client, who was previously alert, is now highly restless and disoriented. The client's pulse is 110 beats/min and blood pressure is 96/58 mmHg. Which action should the practical nurse take first?

Show answer & explanation

Answer: Assess the client's airway, breathing, and oxygen saturation.

Answer

Assess the client's airway, breathing, and oxygen saturation.
Sudden restlessness and disorientation, combined with tachycardia and a borderline low blood pressure, are classic early signs of hypoxia or hypovolemic shock. According to the Airway, Breathing, and Circulation (ABC) priority framework, the nurse must first assess the client's respiratory and oxygenation status to rule out or treat life-threatening complications before pursuing other interventions.

Step-by-Step Solution

1
Analyze the client's sudden change in mental status and vital signs.
The client is demonstrating signs of acute delirium, tachycardia, and borderline hypotension.
Sudden confusion and restlessness in a postoperative client are often early indicators of hypoxia or shock.
2
Determine the priority framework to apply to the situation.
The Airway, Breathing, Circulation (ABC) framework must be utilized.
Life-threatening physiological changes take priority over pain management, routine documentation, or family reassurance.
3
Select the action that addresses the highest priority physiological need.
Assessing airway, breathing, and oxygen saturation directly addresses the most critical potential cause of the client's symptoms.
Identifying and treating hypoxia or circulatory collapse is essential before taking any secondary nursing actions.

Key Concept

Prioritizing ABCs and recognizing early signs of physiological deterioration in postoperative clients.
