Question 101Question →

Following a percutaneous coronary intervention via the right femoral artery, a 74-year-old client is admitted to the telemetry unit for observation. Six hours later, the client becomes highly agitated, complains of severe, deep lower back pain, and insists on getting out of bed to void. The client's heart rate has increased from a baseline of 78 bpm to 110 bpm, and blood pressure has dropped from 130/76 mmHg to 102/64 mmHg. Which action should the practical nurse (PN) take first?

Show answer & explanation

Answer: Instruct the client to remain strictly flat in bed and immediately notify the registered nurse (RN).

Answer

Instruct the client to remain strictly flat in bed and immediately notify the registered nurse (RN).
The client is exhibiting classic signs of a retroperitoneal hemorrhage (severe back pain, agitation, tachycardia, and hypotension) following a femoral artery puncture. The correct answer identifies the urgent need to maintain the flat position to prevent further arterial bleeding and immediately escalate the situation to the RN for advanced emergency management.

Step-by-Step Solution

1
Analyze the client's recent procedure and associated risk factors.
The client underwent a femoral cardiac catheterization, which carries a high risk for arterial bleeding and hematoma formation at the puncture site.
Understanding procedure-specific complications directs the targeted assessment.
2
Evaluate the new onset symptoms.
Severe lower back or flank pain combined with agitation are classic signs of a retroperitoneal hemorrhage, where blood pools internally behind the abdominal cavity.
Identifying hallmark symptoms distinguishes life-threatening complications from routine discomfort.
3
Interpret the vital sign trends.
The increase in heart rate to 110 bpm and drop in blood pressure to 102/64 mmHg indicate early compensated hypovolemic shock.
Objective data confirms the subjective reports of distress and points directly to internal blood loss.
4
Determine the priority PN action.
The PN must prevent further bleeding by keeping the patient flat and immediately escalate care to the RN for emergency medical intervention.
Acute hemorrhage requires rapid medical management (e.g., fluids, blood products, surgical intervention) that is beyond the scope of independent PN practice.

Question 102Question →

A practical nurse (PN) is collecting data on a client who was admitted 12 hours ago with a complete spinal cord injury at the T2 level. The client's baseline blood pressure was 128/78 mm Hg and heart rate was 86 bpm. The client now reports feeling dizzy and lightheaded. Current vital signs are: blood pressure 94/56 mm Hg, heart rate 62 bpm, and respiratory rate 18 breaths/min. The PN notes the client's skin is flushed, warm, and dry to the touch. Which of the following actions should the PN take immediately? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Immediately notify the registered nurse (RN) of the vital sign changes.; Prepare to assist the RN with the administration of intravenous isotonic fluids.; Apply a pulse oximeter and provide supplemental oxygen as prescribed.

Answer

The correct actions are to immediately notify the RN, prepare to assist with intravenous isotonic fluids, and apply a pulse oximeter while providing supplemental oxygen.
The client is exhibiting subtle but classic signs of early neurogenic shock (hypotension, relative bradycardia, and warm/flushed skin due to vasodilation) secondary to a T2 spinal cord injury. The correct priority actions are to escalate the emergency by notifying the RN, support circulation by assisting with intravenous isotonic fluids, and ensure adequate oxygenation by applying supplemental oxygen.

Step-by-Step Solution

1
Compare the current vital signs and physical assessment to the client's baseline.
The blood pressure has dropped significantly (by 34 mm Hg systolic), the heart rate is inappropriately low for the level of hypotension (bradycardia at 62 bpm), and the skin is flushed and warm.
Recognizing subtle deviations from baseline is critical for the early identification of life-threatening complications.
2
Correlate the clinical findings with the client's high thoracic (T2) spinal cord injury.
The cluster of symptoms indicates a loss of sympathetic nervous system tone below the level of the injury, leading to massive vasodilation.
This pathophysiology confirms the development of neurogenic shock rather than hypovolemic shock, which would typically present with compensatory tachycardia and cold, clammy skin.
3
Prioritize nursing interventions based on the practical nurse (PN) scope of practice.
The appropriate actions are notifying the RN to escalate care, preparing to assist with IV fluid resuscitation to correct relative hypovolemia, and applying oxygen to support tissue perfusion.
These actions directly address the immediate ABC priorities (Airway, Breathing, Circulation) without causing harm or exceeding the PN's scope.

Question 103Question →

A practical nurse (PN) is monitoring a client who is receiving a packed red blood cell (PRBC) transfusion. The client suddenly becomes restless and reports severe lower back pain, chills, and shortness of breath. 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 sequence is to first stop the blood transfusion immediately, then replace the IV tubing and initiate an infusion of 0.9% sodium chloride. Next, the PN must notify the registered nurse (RN) and the healthcare provider, followed by obtaining a complete set of vital signs. Finally, the blood bag and attached tubing should be returned to the blood bank.
When a client exhibits signs of an acute hemolytic transfusion reaction (such as severe lower back pain, chills, and dyspnea), the absolute first priority is to stop the transfusion to prevent further exposure to the incompatible blood. Next, the nurse must maintain a patent intravenous line with 0.9% sodium chloride using completely new tubing. Using the old tubing would inadvertently push the remaining reactive blood into the client. After securing IV access, the nurse immediately notifies the RN and healthcare provider to initiate emergency medical interventions. Once help is notified, the nurse assesses vital signs to monitor hemodynamic stability. Finally, after the client is stable, the blood bag, tubing, and associated labels are returned to the blood bank for diagnostic investigation.

Step-by-Step Solution

1
Recognize the clinical manifestations of an acute hemolytic transfusion reaction.
Identifies the life-threatening emergency based on the client's symptoms.
Lower back pain, chills, and dyspnea are hallmark signs of a severe immune response that require immediate intervention.
2
Stop the blood transfusion immediately.
Halts the delivery of the incompatible blood product.
This is the absolute highest priority to prevent further physiological harm and limit the amount of reactive antigen entering the bloodstream.
3
Replace the IV tubing and initiate an infusion of 0.9% sodium chloride.
Maintains a patent IV access route with a compatible isotonic solution.
A patent IV is required for emergency fluid resuscitation and medications. New tubing is essential to avoid pushing the remaining reactive blood in the old tubing into the client.
4
Notify the registered nurse (RN) and the healthcare provider.
Escalates the clinical emergency to the appropriate personnel.
The RN and provider must rapidly evaluate the client and prescribe emergency pharmacological interventions.
5
Obtain a complete set of vital signs.
Establishes an objective clinical baseline of the client's hemodynamic status.
Vital signs help determine the severity of systemic shock and guide ongoing resuscitation efforts.
6
Return the blood bag and attached tubing to the blood bank.
Preserves the physical evidence of the transfusion.
The blood bank must analyze the remaining product and tubing to confirm the cause of the reaction (e.g., ABO incompatibility).

Question 104Question →

An 82-year-old client with a history of early-stage dementia is recovering on the medical-surgical unit three hours after a percutaneous liver biopsy. The client is positioned on the right side and begins complaining of a new, persistent ache in the right shoulder. The nurse observes the client is becoming increasingly drowsy and slightly confused. Current vital signs are a heart rate of 106 beats per minute, blood pressure of 102/60 mm Hg, and a respiratory rate of 22 breaths per minute. Baseline vital signs prior to the procedure were a heart rate of 72 beats per minute and blood pressure of 142/84 mm Hg. Which action is the priority for the nurse to take?

Show answer & explanation

Answer: Ensure the client remains positioned on the right side and urgently report the clinical findings to the supervising nurse.

Answer

The priority action is to ensure the client remains positioned on the right side and to urgently report the clinical findings to the supervising nurse.
The correct answer prioritizes life-saving actions based on subtle clinical cues. A percutaneous liver biopsy carries a high risk of internal bleeding. The client is presenting with a triad of hemorrhage indicators: referred right shoulder pain (caused by blood pooling under the diaphragm and irritating the phrenic nerve), early hemodynamic decompensation (tachycardia and a significant drop in blood pressure from baseline), and decreased cerebral perfusion (manifesting as drowsiness and confusion). By maintaining the right side-lying position, the nurse uses the client's body weight to tamponade the bleeding liver capsule. Simultaneously, urgently escalating these findings ensures the client receives immediate medical interventions for hypovolemic shock.

Step-by-Step Solution

1
Analyze the client's surgical history and current symptoms.
The client had a liver biopsy, a highly vascular procedure with a high risk of bleeding. The new right shoulder pain is a classic sign of referred pain caused by blood accumulating under the diaphragm and irritating the phrenic nerve.
Recognizing procedure-specific complications is essential for early intervention.
2
Evaluate the vital sign trends against baseline measurements.
The heart rate increased from 72 to 106 bpm, and the blood pressure decreased from 142/84 to 102/60 mm Hg. This widened gap indicates compensatory mechanisms failing due to fluid volume loss.
Comparing current vitals to baseline reveals subtle, early signs of hypovolemic shock before profound cardiovascular collapse occurs.
3
Assess the changes in the client's neurological status.
The acute onset of increasing drowsiness and confusion is recognized as a symptom of decreased cerebral perfusion, not a normal aspect of the client's baseline dementia.
Changes in level of consciousness are often the earliest indicator of inadequate tissue oxygenation and hypovolemia.
4
Determine the safest and most effective nursing intervention.
The nurse must maintain the right lateral position to apply pressure to the liver capsule and immediately notify the RN or provider of the impending circulatory crisis.
The PN's scope of practice requires immediate escalation of unstable clients while initiating basic safety measures, such as tamponade positioning.

Question 105Question →

While caring for a 76-year-old client who is two days post-open cholecystectomy, the practical nurse is informed by the unlicensed assistive personnel that the client has suddenly become restless, is picking at the bed linens, and appears disoriented. Current vital signs reveal a heart rate of 108 beats/min and a blood pressure of 102/64 mmHg. Which action should the practical nurse prioritize?

Show answer & explanation

Answer: Measure the client's oxygen saturation and auscultate breath sounds

Answer

Measure the client's oxygen saturation and auscultate breath sounds
In postoperative clients, sudden restlessness, agitation, or confusion are classic early indicators of hypoxia. The brain is extremely sensitive to decreased oxygen delivery, and these behavioral changes often precede significant drops in oxygen saturation or frank cyanosis. Because airway and breathing are the highest priorities in the ABC framework, the most immediate and critical action is to obtain a pulse oximetry reading and evaluate breath sounds to rule out respiratory compromise.

Step-by-Step Solution

1
Analyze the clinical presentation
The client has a sudden onset of restlessness and disorientation, paired with borderline vital signs (HR 108, BP 102/64).
Recognizing sudden changes in mental status is critical, as they are often the earliest indicators of physiological decompensation in older adults.
2
Apply the ABC (Airway, Breathing, Circulation) priority framework
Hypoxia (Breathing) must be ruled out first when acute restlessness and confusion occur.
The brain is highly sensitive to decreased oxygen levels. Restlessness is a hallmark early sign of hypoxia, making respiratory data collection the highest priority.
3
Select the nursing action that addresses the highest priority
Checking oxygen saturation directly assesses for hypoxia.
This action provides immediate, objective data regarding the client's respiratory status, guiding further emergency interventions or notification of the registered nurse.

Question 106Question →

A practical nurse (PN) is collecting data on an older adult client who is 2 hours post-operative following an open bowel resection. Which of the following data collection findings should the PN recognize as early indicators of hypovolemic shock requiring immediate reporting to the registered nurse? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Heart rate increasing steadily from 84 to 114 beats per minute over the last hour.; The client exhibiting new-onset restlessness and frequently asking for sips of water.; Capillary refill time on the fingers is delayed to 5 seconds.

Answer

The findings indicating early hypovolemic shock are the steadily increasing heart rate, new-onset restlessness with increased thirst, and the delayed capillary refill time.
The correct findings highlight the body's early physiological adaptation to fluid loss. As intravascular volume decreases, the sympathetic nervous system initiates compensatory mechanisms to maintain perfusion to vital organs. This results in an increased heart rate (tachycardia) to boost cardiac output, and peripheral vasoconstriction that delays capillary refill. Additionally, early cellular hypoxia and decreased cerebral perfusion often manifest as behavioral changes, such as new-onset restlessness and anxiety, accompanied by an increased physiological drive for thirst.

Step-by-Step Solution

1
Analyze the clinical scenario to identify the client's risk factors.
The client is 2 hours post-operative from major abdominal surgery, placing them at high risk for fluid volume deficit and internal hemorrhage.
Recognizing post-operative risks directs the focus of data collection toward signs of circulatory compromise.
2
Recall the physiological compensatory mechanisms triggered during the early stages of hypovolemic shock.
Early shock activates the sympathetic nervous system, causing tachycardia, peripheral vasoconstriction, and subtle central nervous system changes before blood pressure significantly drops.
Understanding the timeline of physiological adaptation allows the nurse to distinguish between early warning signs and late manifestations.
3
Evaluate each finding against the expected signs of early hypovolemic shock.
Tachycardia, restlessness/thirst, and delayed capillary refill are acute compensatory changes. Incisional pain, slightly lower but normal blood pressure, and a normal hemoglobin level are expected or non-emergent post-operative findings.
This systematic evaluation ensures that life-threatening airway, breathing, and circulation (ABC) complications are prioritized over expected localized symptoms.

Key Concept

Early recognition of hypovolemic shock relies on identifying compensatory sympathetic nervous system responses (tachycardia, restlessness, peripheral vasoconstriction) rather than waiting for a significant drop in blood pressure.
Question 107Question →

A 71-year-old client is 14 hours post-subtotal thyroidectomy. While rounding, the nurse notices the client appears highly anxious, is repeatedly clearing their throat, and complains of a feeling of pressure in the neck. The anterior surgical dressing is clean, dry, and intact. Vital signs reveal a heart rate of 106 beats per minute and blood pressure of 108/68 mm Hg. Which action should the nurse take first?

Show answer & explanation

Answer: Examine the posterior neck area for pooling blood and immediately alert the registered nurse.

Answer

Examine the posterior neck area for pooling blood and immediately alert the registered nurse.
The correct answer directly addresses a life-threatening complication. After neck surgery, frequent throat clearing, feelings of fullness, anxiety, and an increasing heart rate are classic indicators of a hematoma. Because the client is typically in a semi-Fowler or supine position, blood drains to the back of the neck. The nurse must quickly check this dependent area and immediately escalate the situation to the registered nurse for potential rapid airway intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has anxiety, frequent throat clearing, neck pressure, and mild tachycardia 14 hours after a thyroidectomy.
Identifying these specific symptoms is crucial for recognizing postoperative complications.
2
Relate the symptoms to potential complications of the specific surgery.
These symptoms strongly suggest the formation of a hematoma or active hemorrhage compressing the airway.
The neck is a confined space; bleeding quickly leads to life-threatening tracheal deviation and airway obstruction.
3
Evaluate the clinical evidence provided in the stem.
The anterior dressing is dry, but blood follows gravity. The client is likely bleeding internally or dependently.
Understanding anatomical positioning helps the nurse locate hidden bleeding that isn't immediately visible on the surgical incision.
4
Determine the highest priority nursing intervention.
The nurse must assess the dependent area (back of the neck) for blood and notify the RN immediately.
Airway protection is the absolute priority; the RN and provider must be alerted immediately to intervene.

Question 108Question →

An 84-year-old resident in a long-term care facility has a history of mild vascular dementia and a recently placed indwelling urinary catheter. The resident's baseline blood pressure is 142/84 mm Hg, and their baseline heart rate is 72 beats/min. The practical nurse (PN) is called to the room and finds the resident pacing rapidly, speaking incoherently, and occasionally grimacing while clutching their lower abdomen. Current vital signs are: blood pressure 100/62 mm Hg, heart rate 114 beats/min, respiratory rate 26 breaths/min, and temperature 97.4°F (36.3°C). Which of the following is the priority action for the practical nurse (PN) to take?

Show answer & explanation

Answer: Apply supplemental oxygen, ensure the resident's safety, and immediately escalate the findings to the supervising registered nurse.

Answer

The correct priority action is to apply supplemental oxygen, ensure the resident's safety, and immediately escalate the findings to the supervising registered nurse.
The correct action recognizes that this older adult is demonstrating signs of atypical urosepsis leading to distributive shock. Older adults often do not mount a febrile response to infection; instead, they present with hypothermia, acute confusion (delirium), and tachypnea. The significant drop in blood pressure from the resident's baseline, combined with compensatory tachycardia and tachypnea, indicates a life-threatening physiological collapse. Applying oxygen supports the client's ABCs, and immediate escalation to the registered nurse is required because the client needs rapid advanced interventions, such as intravenous fluids and antibiotics.

Step-by-Step Solution

1
Analyze the resident's baseline data compared to current data.
The resident has a significant drop in blood pressure (142/84 to 100/62 mm Hg), new-onset tachycardia (114 beats/min), tachypnea (26 breaths/min), hypothermia, and acute cognitive changes.
Identifying deviations from baseline is critical for recognizing acute physiological deterioration, especially in older adults.
2
Correlate the clinical findings with the client's risk factors.
The resident has a new indwelling urinary catheter, placing them at high risk for a catheter-associated urinary tract infection (CAUTI) progressing to urosepsis.
Older adults often present with atypical signs of infection, such as hypothermia (97.4°F) and acute confusion, rather than a classic fever.
3
Prioritize nursing actions based on the ABCs (Airway, Breathing, Circulation) and scope of practice.
The priority is to address the compromised airway/breathing (tachypnea) with oxygen and immediately escalate to the RN to manage the suspected distributive (septic) shock.
The PN must recognize impending shock and initiate life-saving protocols while rapidly notifying the RN for advanced interventions.

Key Concept

Older adults frequently exhibit atypical manifestations of systemic infection (sepsis), such as acute confusion, hypothermia, and tachypnea, without presenting a fever. A significant drop from baseline blood pressure indicates impending shock and requires immediate ABC interventions and escalation.
Question 109Question →

The practical nurse is caring for an older adult client who sustained a fractured right femur earlier in the day and is awaiting surgical repair. The client, who was previously alert, abruptly becomes highly agitated and exhibits confusion regarding their location. Current vital signs reveal a heart rate of 115 beats per minute, a respiratory rate of 24 breaths per minute, and a blood pressure of 96/58 mm Hg. Which action is the priority for the practical nurse to implement?

Show answer & explanation

Answer: Obtain an immediate oxygen saturation reading and prepare to administer supplemental oxygen.

Answer

The correct action is to prioritize respiratory assessment and oxygenation by obtaining an oxygen saturation reading and preparing to administer supplemental oxygen.
The correct answer addresses the immediate threat to life by prioritizing respiratory assessment and oxygenation. A long bone fracture places the client at high risk for fat embolism syndrome and hypovolemic shock. The sudden onset of confusion, agitation, tachypnea, tachycardia, and borderline hypotension are early, critical clinical indicators of hypoxia and poor tissue perfusion. According to the ABC (airway, breathing, circulation) prioritization framework, evaluating and supporting oxygenation takes absolute precedence over safety interventions, routine monitoring, or pain management.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has a long bone fracture and exhibits sudden confusion, severe agitation, tachypnea, tachycardia, and a low-normal blood pressure.
Identifying acute deviations from a stable baseline is essential for recognizing physiological deterioration.
2
Correlate the assessment findings with potential clinical complications.
The combination of long bone trauma and sudden respiratory and neurological changes strongly suggests a fat embolism or hypovolemic shock, both of which lead to severe hypoxia.
Connecting specific signs and symptoms to the client's risk factors guides accurate clinical judgment and intervention.
3
Apply prioritization frameworks to determine the initial nursing action.
Using the ABC (Airway, Breathing, Circulation) framework, the highest priority is to assess oxygenation status and provide respiratory support.
Life-threatening respiratory or circulatory issues must be stabilized before addressing safety, documentation, or pain management.

Question 110Question →

While evaluating a 79-year-old client being treated for a severe lower extremity soft tissue infection, the practical nurse notes a sudden change in the client's behavior. The client, who was previously alert and cooperative, is now acutely disoriented and continuously picking at their intravenous tubing. The most recent vital signs demonstrate a temperature of 96.8°F (36.0°C), a heart rate of 108 bpm, a blood pressure of 102/62 mm Hg, and a respiratory rate of 24/min. The client's morning baseline blood pressure was 134/76 mm Hg. Which of the following actions should the practical nurse perform first?

Show answer & explanation

Answer: Apply a pulse oximeter to assess oxygenation and elevate the head of the bed.

Answer

The practical nurse should first apply a pulse oximeter and elevate the head of the bed to immediately assess and support the client's airway and breathing.
The correct answer addresses the immediate physiological priority using the ABC (Airway, Breathing, Circulation) framework. Acute confusion in an older adult is a classic early sign of hypoxia or decreased cerebral perfusion, often preceding overt respiratory failure or cardiovascular collapse. The client's tachypnea, tachycardia, relative hypotension (a severe drop from baseline), and hypothermia point to a systemic infection progressing to septic shock. Assessing oxygenation and optimizing breathing by elevating the head of the bed is the most critical first step.

Step-by-Step Solution

1
Analyze the clinical data and the client's baseline.
The client has an active infection and is exhibiting acute confusion, tachypnea, mild tachycardia, relative hypotension (a significant drop from baseline), and hypothermia.
Recognizing trends and deviations from baseline is crucial, as these are hallmark signs of systemic inflammatory response syndrome (SIRS) progressing to sepsis or septic shock in an older adult.
2
Apply the ABC (Airway, Breathing, Circulation) prioritization framework.
The sudden onset of confusion combined with a respiratory rate of 24/min suggests potential hypoxia and inadequate cerebral perfusion.
Physiological needs related to oxygenation and systemic perfusion always take precedence over environmental safety, documentation, or pharmacological investigations.
3
Determine the immediate nursing action within the practical nurse scope of practice.
Assessing oxygen saturation and positioning the client to optimize lung expansion is the immediate priority.
This directly addresses the immediate threat to the client's respiratory and neurological status, gathering critical data before escalating the rapidly deteriorating situation to the registered nurse.

Question 111Question →

An 81-year-old client is receiving intravenous antibiotics for community-acquired pneumonia. The client's admission blood pressure was 142/86 mm Hg with a heart rate of 76/min. The client now appears agitated, is picking at the hospital gown, and repeatedly asks to go home. Current vital signs reveal a blood pressure of 106/64 mm Hg, heart rate of 112/min, and respirations of 26/min. Based on these findings, which intervention should the practical nurse execute first?

Show answer & explanation

Answer: Position the client upright to maximize lung expansion and promptly report the deteriorating status to the supervising registered nurse.

Answer

Position the client upright to maximize lung expansion and promptly report the deteriorating status to the supervising registered nurse.
The client's shift from a hypertensive baseline to borderline hypotension, combined with tachycardia, tachypnea, and sudden agitation, strongly suggests physiological deterioration such as hypoxia or early sepsis. The most critical action is to support breathing by elevating the head of the bed and immediately escalating these findings so advanced interventions can be initiated.

Step-by-Step Solution

1
Analyze the baseline versus current vital signs.
The heart rate has increased from 76 to 112/min, blood pressure has dropped from 142/86 to 106/64 mm Hg, and respirations are elevated at 26/min.
Comparing current data to baseline is essential to identify trends indicating clinical deterioration.
2
Interpret the meaning of the behavioral changes in this clinical context.
Agitation and restlessness in a client with pneumonia and worsening hemodynamics indicate hypoxia or impending septic shock, rather than simple confusion or dementia.
Sudden mental status changes are often the earliest sign of compromised oxygenation and cerebral perfusion in older adults.
3
Determine the priority action within the practical nursing scope of practice.
The practical nurse must immediately support the client's breathing (elevating the head) and escalate the findings to the registered nurse.
Acute physiological decompensation requires immediate Airway, Breathing, and Circulation (ABC) support and advanced RN/provider intervention.

Question 112Question →

A practical nurse (PN) is assisting with the care of a client who is 48 hours postoperative following an abdominal bowel resection. The client experiences a severe bout of coughing, followed by a sudden report of "my stomach tearing open." The PN inspects the surgical site and observes an active wound evisceration. Arrange the following nursing actions in the correct order of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of interventions is to first secure assistance while staying with the client, then properly position the client to reduce abdominal tension, cover the eviscerated bowel with sterile moistened dressings, obtain vital signs, and finally ensure the client remains NPO.
When an abdominal evisceration occurs, it is a life-threatening surgical emergency requiring a highly specific sequence of actions. The absolute highest priority is to ensure the client is not left alone while simultaneously mobilizing help and necessary sterile supplies via the call light. Because gathering supplies takes time, the immediate next step is to mechanically limit the evisceration by placing the client in a low Fowler's position with flexed knees to reduce intra-abdominal pressure. Once supplies are handed to the nurse, covering the bowel with sterile, saline-soaked gauze is critical to preserve tissue viability. Only after the exposed organs are physically protected should the nurse transition to systemic monitoring (vital signs) to assess for shock, followed by final preoperative preparations such as reinforcing NPO status.

Step-by-Step Solution

1
Ensure immediate safety by activating the call light.
Additional staff are alerted to bring sterile supplies and notify the healthcare provider.
The practical nurse cannot leave the unstable client to fetch supplies or make phone calls during a surgical emergency.
2
Position the client in low Fowler's with knees bent.
Tension on the abdominal musculature is immediately relieved.
Lowering intra-abdominal pressure mechanically stops further bowel loops from eviscerating while waiting for supplies to be brought to the bedside.
3
Cover the evisceration with moist, sterile dressings.
The protruding bowel is protected from the external environment.
Exposed viscera rapidly dry out and become necrotic; sterile saline preserves tissue viability and minimizes infection risk.
4
Assess the client's vital signs.
Baseline systemic hemodynamic data is collected.
Monitoring is crucial for detecting early signs of hemorrhagic shock, which follows the immediate stabilization of the wound itself.
5
Ensure the client remains strictly NPO.
The client is prepared for safe anesthesia administration.
Evisceration requires an emergency surgical repair; confirming NPO status prevents dangerous aspiration during the upcoming surgery.

Question 113Question →

A practical nurse (PN) is caring for a 74-year-old client who sustained a closed pelvic fracture 40 hours ago. The client, who was previously alert and cooperative, is now picking at the bedsheets and speaking to a deceased relative. Current vital signs are: heart rate 116 bpm, respiratory rate 26 breaths/min, blood pressure 104/62 mm Hg, and oxygen saturation 89% on room air. Which action should the PN take first?

Show answer & explanation

Answer: Apply supplemental oxygen and urgently notify the registered nurse.

Answer

The correct action is to apply supplemental oxygen and urgently notify the registered nurse.
The client is exhibiting classic signs of acute hypoxia and potentially fat embolism syndrome, a life-threatening complication associated with pelvic fractures. The sudden onset of confusion, combined with tachypnea (RR 26), tachycardia (HR 116), and an oxygen saturation of 89%, indicates severe respiratory and hemodynamic compromise. According to the ABCs (Airway, Breathing, Circulation) framework, the priority action within the practical nurse's scope is to immediately apply oxygen to address the critical respiratory deficit and rapidly escalate the situation to the RN for advanced medical intervention.

Step-by-Step Solution

1
Analyze the clinical cues presented by the client.
The client has sudden confusion, tachypnea, tachycardia, borderline hypotension, and hypoxia after a recent pelvic fracture.
Identifying abnormal data is the first step in clinical judgment.
2
Correlate the findings with potential physiological complications.
The combination of symptoms strongly indicates a life-threatening complication, such as fat embolism syndrome or hemorrhagic shock, leading to cerebral hypoxia.
Pelvic and long bone fractures carry a high risk for fat emboli, which peak 24 to 72 hours post-injury.
3
Prioritize interventions using the Airway, Breathing, and Circulation (ABC) framework.
Breathing and oxygenation are severely compromised (respiratory rate 26, oxygen saturation 89%).
Physiological needs related to survival always take precedence over psychosocial or comfort needs.
4
Select the most appropriate action within the PN scope of practice.
Applying oxygen addresses the immediate physiological deficit, and notifying the RN escalates care for emergent medical management.
The PN must recognize acute deterioration and initiate basic life-saving measures while seeking advanced assistance.

Question 114Question →

An 68-year-old client is receiving treatment for a respiratory infection. The client's medication administration record includes a scheduled oral prednisone taper and a recently prescribed course of oral levofloxacin. While walking to the restroom, the client suddenly reports severe, sharp pain and swelling in the back of the right ankle. Which action should the practical nurse take?

Show answer & explanation

Answer: Instruct the client to avoid bearing weight on the right foot, withhold the levofloxacin, and notify the registered nurse.

Answer

The practical nurse should instruct the client to avoid bearing weight on the affected foot, withhold the levofloxacin, and immediately notify the registered nurse.
Levofloxacin is a fluoroquinolone antibiotic associated with a severe risk of tendinitis and tendon rupture, most commonly affecting the Achilles tendon. This risk is exponentially increased in clients over the age of 60 and those receiving concurrent corticosteroid therapy, such as prednisone. Because the client is exhibiting classic signs of Achilles tendon injury (sudden sharp pain and swelling in the heel area), the practical nurse must immediately withhold the levofloxacin to prevent further toxicity, instruct the client not to bear weight on the foot to prevent a full rupture, and notify the registered nurse so a comprehensive assessment can be performed.

Step-by-Step Solution

1
Identify the pharmacological risk factors presented in the clinical scenario.
The client is an older adult taking levofloxacin (a fluoroquinolone) and prednisone (a corticosteroid).
Fluoroquinolones carry a black box warning for tendinitis and tendon rupture. This risk is significantly heightened in clients over age 60 and those taking concurrent corticosteroids.
2
Correlate the client's new symptoms with the pharmacological risk profile.
The sudden, sharp pain and swelling in the back of the right ankle strongly suggests Achilles tendinitis or an impending tendon rupture.
Recognizing adverse drug reactions is a critical component of safe medication administration and continuous client monitoring.
3
Determine the appropriate practical nursing intervention based on safety and scope of practice.
The nurse must prevent further musculoskeletal injury by restricting weight-bearing, withhold the offending medication, and escalate the acute clinical change to the registered nurse.
The LPN/LVN is strictly responsible for withholding unsafe medications and promptly reporting acute condition changes to the RN or provider for further medical assessment.

Show answer & explanation

Answer

The correct sequence is to first verify suction pressure, then hyperoxygenate the client, advance the catheter without suction, withdraw slightly upon meeting resistance, and finally apply intermittent suction while rotating and withdrawing.
The correct sequence ensures the procedure is performed safely and minimizes severe physiological risks. First, the suction pressure is verified to prevent excessive vacuum trauma. Second, the client is hyperoxygenated to provide an oxygen reserve, as suctioning removes air alongside secretions. Third, the catheter is advanced without suction to avoid damaging the mucosal lining on the way down. Fourth, the catheter is withdrawn slightly after meeting resistance at the carina to prevent suctioning directly on sensitive bifurcated tissue. Finally, intermittent suction is applied while rotating and withdrawing to safely clear the airway.

Step-by-Step Solution

1
Verify the wall suction pressure is set to between 80 and 120 mm Hg.
Equipment is safely calibrated.
Prevents tracheal trauma from excessive negative pressure.
2
Hyperoxygenate the client using a manual resuscitation bag connected to 100% oxygen.
Client's oxygen reserves are maximized.
Prevents severe hypoxemia during the suctioning process, as suctioning removes both oxygen and secretions.
3
Advance the sterile catheter into the artificial airway without applying suction.
Catheter is positioned near the pooled secretions.
Applying suction during insertion strips the mucosal lining and depletes oxygen before reaching the target area.
4
Withdraw the catheter 0.5 to 1 cm (0.2 to 0.4 in) after meeting resistance.
Catheter tip is moved away from the sensitive carina.
The carina is highly sensitive and prone to bleeding or inducing severe bronchospasm if direct suction is applied to it.
5
Apply intermittent suction while rotating the catheter during withdrawal.
Secretions are effectively cleared with minimal trauma.
Rotating prevents the catheter from adhering to one spot on the tracheal wall, and limiting suction to withdrawal prevents prolonged hypoxia.

Question 116Question →

A practical nurse (PN) is providing care for several clients on a medical-surgical unit. Which of the following nursing actions best demonstrate appropriate reduction of risk potential and adherence to safe clinical practice? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Verifying two distinct client identifiers, such as name and date of birth, prior to drawing a blood sample for a type and crossmatch.; Elevating the head of the bed and notifying the registered nurse (RN) immediately when a client receiving continuous enteral feedings develops new-onset coarse crackles.

Answer

The correct actions include verifying two distinct client identifiers before drawing blood for a crossmatch and elevating the head of the bed while notifying the RN for a client with enteral feedings who develops coarse crackles.
The correct nursing actions actively protect the client from harm. Consistently verifying two distinct identifiers prevents wrong-client errors during high-risk procedures like blood typing. Additionally, recognizing new-onset crackles during enteral feeding as a sign of potential aspiration and intervening by raising the head of the bed and notifying the RN demonstrates competent risk mitigation.

Step-by-Step Solution

1
Analyze each option to determine if the nursing action is safe, within the PN scope of practice, and effectively reduces client risk.
Identify actions that proactively prevent complications (e.g., rigorously verifying identifiers, escalating acute respiratory distress).
Risk reduction requires the PN to anticipate potential harm and take preventative or rapid corrective measures.
2
Evaluate the clinical data provided in the incorrect options against normal physiological parameters and the legal scope of practice.
Recognize that a potassium of 2.8 mEq/L is a critical lab value, IV push medications are out of scope, borderline hypotensive vitals indicate potential shock, and skipping safety checks violates medication administration rights.
Identifying what the PN should NOT do is just as important as knowing correct interventions in order to maintain a strictly safe care environment.

Key Concept

The practical nurse effectively reduces risk potential by closely monitoring for early signs of complications, strictly adhering to safety protocols, recognizing critical clinical data, and maintaining boundaries within their legal scope of practice.

Question 117Question →

A practical nurse is providing care for a client who is 3 days postoperative following an exploratory laparotomy. The client coughs forcefully, and the nurse observes a sudden separation of the surgical incision with loops of bowel protruding. In what order should the nurse perform 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 call for assistance while staying with the client, then position the client to reduce abdominal tension, next cover the exposed organs with moist sterile dressings, and finally obtain vital signs.
When a client experiences wound evisceration, it is a life-threatening complication that requires immediate risk reduction. The priority is always client safety, which begins by calling for help while staying at the bedside. The next immediate physical need is to stop further evisceration by placing the client in a low Fowler's position with flexed knees to reduce abdominal tension. Once the tension is reduced, the nurse must protect the exposed tissue from necrosis by covering it with sterile, saline-soaked dressings. Finally, after the immediate physical threat is stabilized, the nurse assesses vital signs to monitor for shock while waiting for the surgical team.

Step-by-Step Solution

1
Initiate the emergency response.
Call for immediate assistance while remaining at the bedside.
Wound evisceration is a surgical emergency. The nurse must immediately secure help without leaving the unstable client alone.
2
Minimize further organ protrusion.
Place the client in a low Fowler's position with the knees flexed.
This specific position significantly reduces tension on the abdominal muscles, preventing more bowel from protruding through the incision.
3
Protect the exposed tissues.
Cover the bowel with sterile dressings soaked in sterile normal saline.
Exposed bowel can quickly dry out and become necrotic. A moist, sterile environment preserves the tissue until surgical intervention occurs.
4
Monitor for systemic deterioration.
Obtain and record the client's vital signs.
Evisceration can lead to rapid fluid shifts and hypovolemic or neurogenic shock, requiring close hemodynamic monitoring.

A practical nurse 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 and chills. In what order should the practical nurse perform 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: Stop the blood transfusion, initiate 0.9% sodium chloride with new tubing, obtain vital signs, notify the registered nurse and healthcare provider, and finally send the remaining blood and tubing to the blood bank.
When a client exhibits signs of a severe transfusion reaction, such as lower back pain and chills, the absolute first priority is to stop the infusion. Once the source of harm is stopped, the nurse must maintain IV access using normal saline and new tubing to prepare for emergency medication administration. After securing the line, the nurse obtains vital signs to report a complete clinical picture to the RN and healthcare provider. Finally, the blood and tubing are sent to the blood bank per facility protocol for diagnostic analysis.

Step-by-Step Solution

1
Identify the immediate life threat and intervene.
The transfusion is stopped immediately.
Lower back pain and chills are classic signs of a hemolytic transfusion reaction. The source of the reaction must be halted immediately to minimize harm.
2
Maintain vascular access without worsening the reaction.
0.9% sodium chloride is infused through completely new tubing.
If the existing tubing is flushed, the remaining blood in the line will be pushed into the client. New tubing ensures only normal saline enters the vein, keeping the line open for emergency drugs.
3
Assess the client's physiological status.
A full set of vital signs is obtained.
The nurse needs current baseline data (blood pressure, heart rate, temperature, oxygen saturation) to understand the physiological impact of the reaction.
4
Escalate the situation to higher-level providers.
The RN and healthcare provider are notified.
The provider needs the assessment data to order appropriate interventions, such as antihistamines, corticosteroids, or vasopressors.
5
Preserve evidence for institutional analysis.
The blood bag and tubing are sent to the blood bank.
The blood bank must analyze the remaining product to identify cross-matching errors or bacterial contamination.

Question 119Question →

A practical nurse (PN) is caring for a 75-year-old client who was admitted with severe viral gastroenteritis. During morning care, the PN notes that the client is extremely lethargic and difficult to wake up. The client's heart rate is 116 beats per minute and blood pressure is 92/56 mm Hg. What is the priority action for the PN?

Show answer & explanation

Answer: Notify the registered nurse (RN) immediately about the changes in vital signs and mental status.

Answer

The correct action is to immediately notify the registered nurse (RN) about the abnormal vital signs and lethargy.
The client is exhibiting clear signs of hypovolemic shock due to fluid loss from severe gastroenteritis, including tachycardia, hypotension, and altered mental status. The practical nurse must recognize these critical changes as a failure of physiological adaptation and immediately escalate the findings to the registered nurse for prompt medical intervention.

Step-by-Step Solution

1
Analyze the client's vital signs and mental status.
The heart rate of 116 bpm and blood pressure of 92/56 mm Hg indicate hemodynamic instability. The extreme lethargy indicates decreased brain perfusion.
Recognizing deviations from normal physiological baselines is the first step in clinical judgment.
2
Identify the underlying physiological process.
The client has a history of severe gastroenteritis, making fluid volume deficit and hypovolemic shock the primary concern.
Connecting the symptoms to the admitting diagnosis helps determine the urgency of the situation.
3
Determine the appropriate nursing intervention within the PN scope of practice.
The PN must report these critical findings to the RN immediately.
Acute physiological decompensation requires rapid escalation to the RN or provider for advanced assessment and treatment orders.

Question 120Question →

A practical nurse (PN) is caring for a client who is 24 hours postpartum. The client reports feeling slightly dizzy when sitting up. The PN notes the heart rate is 102 beats per minute, blood pressure is 98/60 mm Hg, and the perineal pad is completely saturated with bright red blood. Which action should the PN take first?

Show answer & explanation

Answer: Palpate the uterine fundus and notify the registered nurse (RN) immediately.

Answer

The priority action is to palpate the uterine fundus and notify the registered nurse (RN) immediately to address the active hemorrhage.
The client is exhibiting clear signs of postpartum hemorrhage (saturated pad, bright red blood) leading to early hypovolemic shock (dizziness, tachycardia, borderline hypotension). The immediate priority is to physically intervene by palpating and massaging the fundus to stimulate uterine contraction, while simultaneously alerting the RN for emergency medical management.

Step-by-Step Solution

1
Analyze the client's symptoms and vital signs.
The client has dizziness, tachycardia, mild hypotension, and a saturated perineal pad.
Identifying these findings recognizes the classic presentation of postpartum hemorrhage and early hypovolemic shock.
2
Determine the most critical physiological need.
The immediate threat is excessive blood loss affecting circulation.
According to the ABCs (Airway, Breathing, Circulation) framework, active bleeding is a circulation emergency.
3
Select the nursing intervention that directly addresses the emergency.
Palpating and massaging the fundus helps the uterus contract, and notifying the RN escalates the critical situation.
Direct action to stop the bleeding and escalating to the RN are within the PN scope of practice for emergent stabilization.
