The practical nurse (PN) is collecting data on a client who is 4 hours postpartum following a vaginal delivery of a large-for-gestational-age newborn. Which assessment findings indicate a complication of physiological adaptation requiring immediate notification of the registered nurse (RN)? Select all that apply.

Select all that apply

Show answer & explanation

Answer: A perineal pad completely saturated with blood within 20 minutes.; Resting heart rate increasing from 76 to 114 beats per minute.; Client report of severe, unremitting perineal pressure.

Answer

The correct findings requiring immediate notification are rapid pad saturation, a progressively increasing resting heart rate, and severe, unremitting perineal pressure.
The correct selections represent acute, life-threatening complications of postpartum adaptation. A rapidly saturated pad indicates overt hemorrhage. Tachycardia is a subtle, early compensatory mechanism for hypovolemia. Unremitting perineal pressure strongly suggests a concealed hemorrhage (hematoma). All three require emergency intervention to prevent severe hemodynamic instability.

Step-by-Step Solution

1
Analyze the client's current status and risk factors.
The client is 4 hours postpartum after delivering a large-for-gestational-age infant, placing her at high risk for uterine atony, hemorrhage, and perineal trauma.
Identifying specific clinical risks guides the PN to anticipate potential life-threatening complications.
2
Evaluate each finding to differentiate between expected physiological adaptation and acute decompensation.
Heavy bleeding, tachycardia, and severe localized pressure indicate active or concealed blood loss. Uterine cramping during feeding, slight temperature elevation, and elevated WBCs are expected normal variants in the immediate postpartum period.
The PN must accurately interpret clinical data to avoid missing early signs of shock or escalating normal findings unnecessarily.
3
Determine the priority nursing action based on the identified data.
The abnormal findings threaten Airway, Breathing, and Circulation (ABCs) via hypovolemic shock and require immediate escalation to the RN for medical intervention.
Prompt recognition and reporting of clinical deterioration fall squarely within the PN scope of practice for maintaining physiological integrity.

Key Concept

Early recognition of postpartum hemorrhage and hematoma versus expected normal physiological adaptations (afterpains, transient hyperthermia, and leukocytosis).
Question 2Question →

While checking on a client who underwent a subtotal thyroidectomy earlier in the shift, the practical nurse observes that the client is unusually restless. The client points to the surgical area and whispers, "It feels really tight in my neck." Which action should the nurse take first?

Show answer & explanation

Answer: Evaluate the client's respiratory rate, effort, and oxygen saturation.

Answer

The nurse must first evaluate the client's respiratory rate, effort, and oxygen saturation to assess for an airway obstruction.
Following a thyroidectomy, the client is at an elevated risk for airway compromise due to localized swelling, edema, or hemorrhage (hematoma formation). Restlessness is a classic early sign of hypoxia, and the sensation of neck tightness strongly suggests physical airway compression. Applying the ABC (Airway, Breathing, Circulation) framework dictates that the nurse must assess the client's respiratory status and airway patency immediately before initiating any other intervention.

Step-by-Step Solution

1
Analyze the client's clinical cues.
The client had a recent neck surgery (thyroidectomy) and is showing signs of new restlessness along with a subjective feeling of throat tightness.
Recognizing these cues is essential because the surgical site is directly adjacent to the trachea, making the client highly vulnerable to local swelling or hemorrhage.
2
Apply the ABC (Airway, Breathing, Circulation) priority framework.
Airway assessment becomes the immediate clinical priority over addressing pain or client positioning.
Restlessness is an early indicator of hypoxia, and a tight throat suggests possible airway compression from a hematoma, requiring urgent respiratory evaluation.

Question 3Question →

A 68-year-old client is on bed rest in skeletal traction after suffering a fractured femur. During mid-afternoon rounding, the client appears anxious, shifts frequently in bed, and expresses intense thirst. Vital signs collected at this time show a heart rate of 112 beats/min, blood pressure of 102/66 mm Hg, and a respiratory rate of 24 breaths/min. The baseline vitals taken upon arrival were a heart rate of 82 beats/min, blood pressure of 130/76 mm Hg, and a respiratory rate of 16 breaths/min. Which action should the practical nurse prioritize?

Show answer & explanation

Answer: Communicate the assessment findings to the supervising registered nurse.

Answer

Communicate the assessment findings to the supervising registered nurse.
The correct answer demonstrates an understanding of early shock recognition. Tachycardia, tachypnea, narrowing pulse pressure, restlessness, and thirst are classic early signs of hypovolemia, particularly dangerous in a client with a femur fracture capable of concealing massive internal bleeding. The practical nurse must immediately escalate these findings to the registered nurse for rapid medical intervention.

Step-by-Step Solution

1
Analyze the client's current assessment data compared to baseline.
The client has developed tachycardia, tachypnea, hypotension, anxiety, and thirst.
Identifying trends in vital signs is essential for recognizing physiological deterioration.
2
Correlate the findings with the client's diagnosis and risk factors.
A fractured femur carries a high risk for significant internal bleeding and subsequent hypovolemic shock.
Understanding the clinical context helps interpret the meaning of borderline or changing vital signs.
3
Determine the most appropriate intervention within the practical nurse's scope of practice.
The priority is to report these critical changes to the registered nurse immediately for advanced assessment and intervention.
Early recognition and rapid escalation of care are critical to prevent severe complications of shock.

Question 4Question →

A practical nurse (PN) is collecting data on a 78-year-old client who is receiving intravenous antibiotics for a severe urinary tract infection. Which of the following assessment findings should the PN identify as early indicators of systemic decompensation and report to the registered nurse (RN) immediately? Select all that apply.

Select all that apply

Show answer & explanation

Answer: A resting heart rate of 114 beats/min and a blood pressure of 96/58 mm Hg; New-onset restlessness and the client stating they are waiting for a train; A respiratory rate of 26 breaths/min with shallow chest expansion

Answer

The correct findings are a resting heart rate of 114 beats/min with a blood pressure of 96/58 mm Hg, new-onset restlessness with confusion, and a respiratory rate of 26 breaths/min.
The correct options indicate acute systemic deterioration (sepsis), prioritizing Airway, Breathing, and Circulation (ABC) issues. Tachycardia with borderline hypotension suggests early shock. Tachypnea is a primary respiratory compensatory mechanism during systemic stress. Furthermore, older adults frequently exhibit acute confusion (delirium) as a primary sign of hypoxia or worsening infection.

Step-by-Step Solution

1
Analyze the client's current diagnosis and primary risk factors.
The older adult client has a severe urinary tract infection, placing them at high risk for the infection spreading systemically (sepsis).
Identifying the primary risk helps distinguish expected localized symptoms from emergent systemic complications.
2
Evaluate vital signs for Airway, Breathing, and Circulation (ABC) compromise.
A heart rate of 114 beats/min with borderline hypotension (96/58 mm Hg) and a respiratory rate of 26 breaths/min indicate physiological stress.
ABCs are the highest priority in acute care, and these borderline vital signs are classic early indicators of shock and respiratory decompensation.
3
Assess for acute neurological changes compared to baseline.
New-onset restlessness and confusion (delirium) are critical acute findings, distinguishing them from the chronic gradual forgetfulness reported by the spouse.
In older adults, acute mental status changes are often the first sign of hypoxia or systemic infection.
4
Compare emergent findings with expected localized symptoms.
Mild suprapubic pain and cloudy urine are localized, expected findings that do not require immediate emergency escalation.
Prioritization requires the nurse to address systemic physiological instability before expected, chronic, or local symptoms.

Question 5Question →

During the night shift, a nurse is evaluating an 82-year-old client who had a partial gastrectomy 48 hours ago. The client, who was previously resting quietly, is now agitated, confused, and trying to pull off the surgical dressing. Clinical findings include a heart rate of 118 beats/min, a respiratory rate of 26 breaths/min, and a blood pressure of 100/62 mm Hg. The client is rubbing their abdomen and groaning. Which action should the nurse prioritize?

Show answer & explanation

Answer: Assess the client's oxygen saturation level and apply prescribed supplemental oxygen.

Answer

The priority action is to assess the client's oxygen saturation level and apply prescribed supplemental oxygen.
The client is exhibiting early signs of hypoxia and potential shock, indicated by new-onset agitation, tachycardia, tachypnea, and borderline hypotension. In the physiological adaptation phase following surgery, acute changes in mental status combined with these vital signs prioritize the need for immediate respiratory support and oxygenation assessment based on the ABCs.

Step-by-Step Solution

1
Analyze the client's change in mental status and vital signs.
The client exhibits sudden onset agitation, tachycardia (118 beats/min), tachypnea (26 breaths/min), and borderline hypotension (100/62 mm Hg).
Recognizing acute changes is essential for identifying potential life-threatening complications such as shock or hypoxia in the post-operative period.
2
Apply the Airway, Breathing, Circulation (ABC) prioritization framework.
The client's symptoms strongly suggest impaired oxygenation, which takes clinical precedence over pain management or environmental modifications.
The ABC framework guides nurses to address the most critical and immediate threats to life first.
3
Determine the initial nursing intervention.
Assessing oxygenation status and providing prescribed respiratory support directly addresses the most critical physiological need.
Restoring adequate oxygenation is the immediate priority before treating pain or attempting to reorient a confused client.

Key Concept

Question 6Question →

Following the morning handoff report, a practical nurse (PN) begins data collection for a group of assigned clients. Which client findings represent acute physiological deterioration and require immediate intervention? Select all that apply.

Select all that apply

Show answer & explanation

Answer: A client with a deep vein thrombosis who suddenly develops a cough and rapid breathing.; A client who is 2 hours post-appendectomy and exhibits a steady heart rate increase from 80 to 115 beats per minute.; A client receiving intravenous insulin whose skin becomes pale, cold, and clammy while becoming highly agitated.

Answer

The correct findings indicating acute physiological deterioration are the client with a deep vein thrombosis developing a cough and rapid breathing, the post-appendectomy client with a rising heart rate, and the client on insulin exhibiting pale, clammy skin with agitation.
The correct findings all represent acute, life-threatening physiological changes. Sudden respiratory distress in a DVT client suggests a pulmonary embolism. A rising heart rate post-surgery is a classic early sign of internal bleeding and shock. Agitation with cold, clammy skin during insulin therapy indicates profound hypoglycemia. All three require immediate nursing intervention.

Step-by-Step Solution

1
Evaluate the client with deep vein thrombosis (DVT) for airway and breathing compromise.
The sudden onset of a cough and rapid breathing indicates a potential pulmonary embolism.
DVT clots can dislodge and travel to the lungs, creating a severe, life-threatening respiratory emergency.
2
Evaluate the post-appendectomy client and the client receiving insulin for systemic instability.
The rising heart rate indicates early hypovolemic shock, and pale, clammy skin with agitation indicates severe hypoglycemia.
Both represent acute, life-threatening circulatory and metabolic changes that demand urgent medical treatment.
3
Evaluate the remaining clients to differentiate acute deterioration from expected or non-emergent findings.
The clients with the tibia fracture, advanced dementia, and postpartum status have expected or non-life-threatening findings.
Expected pain, baseline cognitive disorientation, and normal lochia flow do not take precedence over ABC emergencies.

Question 7Question →

During a routine rounding shift, a client who sustained a complete T4 spinal cord injury three months ago suddenly complains of blurred vision and an intense, pounding headache. Assessment reveals a blood pressure reading of 215/115 mm Hg, a heart rate of 52 beats per minute, and heavy diaphoresis on the face and neck. Determine the correct priority sequence for the interventions the nurse must implement. (Place the most urgent action at the top and the final action at the bottom.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first elevate the head of the bed, then loosen any restrictive clothing, followed by inspecting the urinary catheter for obstructions, and finally notifying the registered nurse.
In autonomic dysreflexia, the client experiences a life-threatening hypertensive crisis due to an exaggerated sympathetic response to a noxious stimulus below the level of the spinal cord injury (typically T6 or higher). The absolute first priority is to elevate the head of the bed to a sitting position, which uses gravity to induce orthostatic hypotension and rapidly lower the blood pressure. Next, the nurse should loosen any restrictive clothing, as this serves as a quick removal of an external noxious stimulus. Third, the nurse must assess for and remove the most common internal trigger, which is a distended bladder (e.g., checking the catheter for kinks). Finally, the RN must be notified so that pharmacological interventions can be prepared if the symptoms persist despite these initial nursing actions.

Step-by-Step Solution

1
Recognize the clinical emergency.
The client is identified as experiencing autonomic dysreflexia.
The combination of a T4 spinal cord injury, sudden profound hypertension, bradycardia, headache, and diaphoresis above the injury level are hallmark signs of this life-threatening syndrome.
2
Prioritize immediate physiological stabilization to prevent a stroke.
Elevate the head of the bed to a sitting position.
Sitting the client upright induces orthostatic hypotension, which is the fastest non-pharmacological method to reduce the dangerously high blood pressure.
3
Remove external noxious stimuli.
Loosen any tight or restrictive clothing.
Constrictive clothing can act as an external irritant that fuels the uninhibited sympathetic response below the level of the spinal cord injury.
4
Identify and resolve internal noxious stimuli.
Inspect the urinary catheter and drainage tubing for kinks.
Bladder distention is the most frequent internal trigger for autonomic dysreflexia. Relieving an obstruction removes the primary stimulus causing the hypertensive crisis.
5
Escalate care.
Notify the registered nurse (RN).
If nursing interventions fail to remove the stimulus or lower the blood pressure, the RN and healthcare provider must initiate pharmacological interventions (e.g., administering nifedipine or nitrates).

Key Concept

Autonomic dysreflexia is a medical emergency requiring strict sequential interventions: immediate upright positioning to lower blood pressure, removal of noxious stimuli (external then internal), and rapid escalation of care.
Question 8Question →

A practical nurse (PN) is reviewing the morning data for four assigned clients on a medical-surgical unit. Which client should the PN evaluate first?

Show answer & explanation

Answer: A client admitted overnight following a motor vehicle crash with a pelvic fracture, who has a resting heart rate of 114 bpm and a blood pressure of 106/64 mmHg

Answer

The client admitted overnight following a motor vehicle crash with a pelvic fracture, who has a resting heart rate of 114 bpm and a blood pressure of 106/64 mmHg.
The correct answer is the client with a pelvic fracture because a heart rate of 114 bpm and a borderline blood pressure of 106/64 mmHg are early, compensatory signs of hypovolemic shock. Pelvic fractures carry a notoriously high risk of massive internal retroperitoneal bleeding. This client is physiologically unstable and requires immediate evaluation and escalation to the registered nurse (RN).

Step-by-Step Solution

1
Analyze the clinical data for each assigned client to identify acute, life-threatening conditions.
The trauma client exhibits tachycardia (heart rate 114 bpm) and borderline hypotension (106/64 mmHg).
Prioritization requires identifying the most physiologically unstable client first.
2
Apply the ABCs (Airway, Breathing, Circulation) framework.
The trauma client's vital signs indicate a potential circulation compromise (hypovolemia/hemorrhage).
Circulation issues take strict priority over pain management, chronic confusion, or stable hypertension.
3
Compare the urgency of all client presentations.
The potential for massive internal hemorrhage in the pelvic fracture client is the most immediate threat.
Early recognition of shock allows for prompt intervention to prevent irreversible cardiovascular collapse.

Key Concept

Question 9Question →

An older adult client is hospitalized for observation following a mechanical fall that caused blunt abdominal trauma. During the night shift, the nurse notes that the client has become restless and mildly confused about their current location. Vital signs demonstrate a heart rate of 114 beats per minute, a blood pressure of 102/74 mm Hg, and a respiratory rate of 22 breaths per minute. The client's peripheral pulses are weak and extremities are cool. Which action should the nurse take first?

Show answer & explanation

Answer: Palpate the abdomen for firmness or distention and notify the charge nurse immediately.

Answer

The nurse should immediately assess the abdomen for signs of internal bleeding (firmness or distention) and notify the charge nurse.
The correct answer identifies that the client is exhibiting early signs of compensated hypovolemic shock due to internal bleeding. The combination of tachycardia, tachypnea, cool extremities, weak pulses, and new-onset confusion in a trauma client are critical indicators of decreased perfusion. The practical nurse must immediately collect targeted data regarding the abdomen and escalate these findings to the charge nurse for prompt medical intervention.

Step-by-Step Solution

1
Analyze the client's history and current assessment data.
The client has a history of blunt abdominal trauma and is now exhibiting tachycardia, tachypnea, weak pulses, cool extremities, and new-onset confusion.
Identifying the complete clinical picture is necessary to determine the underlying physiological process.
2
Correlate the physical findings with potential complications.
The combination of these symptoms indicates activation of the sympathetic nervous system, pointing to early compensated hypovolemic shock.
Recognizing shock early is critical before the client's blood pressure drops and they become hemodynamically unstable.
3
Determine the priority nursing intervention within the practical nurse scope of practice.
The priority is to gather targeted data regarding the suspected source of bleeding (the abdomen) and immediately escalate the findings.
Addressing circulation (the 'C' in ABCs) takes precedence over pain management, routine monitoring, or treating the confusion as an isolated behavioral issue.

Following an abdominal hysterectomy, a client is transferred to the surgical unit. During the initial data collection, the practical nurse notes a heart rate of 114 beats/min and a blood pressure of 94/58 mm Hg. The client states, 'I feel a little nauseous and my incision hurts.' Which action should the nurse take first?

Show answer & explanation

Answer: Notify the registered nurse about the current vital signs.

Answer

The correct action is to notify the registered nurse about the current vital signs.
The client is exhibiting tachycardia and borderline hypotension, which are early physiological adaptations to fluid volume deficit or hemorrhage following surgery. Within the practical nursing scope of practice, recognizing these signs of potential shock requires immediate escalation to the registered nurse for further assessment and intervention.

Step-by-Step Solution

1
Evaluate the client's vital signs and postoperative status.
The heart rate of 114 beats/min and blood pressure of 94/58 mm Hg are identified as abnormal deviations from expected postoperative parameters.
Tachycardia and mild hypotension are early physiological adaptations signaling potential hypovolemia or hemorrhage.
2
Prioritize nursing care based on the ABC (Airway, Breathing, Circulation) framework.
Circulatory stability is prioritized over the client's reports of pain and nausea.
Addressing potential shock takes clinical precedence over general comfort measures.
3
Determine the safest action within the practical nursing scope of practice.
The abnormal findings are immediately reported to the registered nurse.
The practical nurse must escalate signs of acute instability to ensure prompt medical or advanced nursing intervention.

The client's current vital signs are: heart rate 112 beats/min, blood pressure 106/68 mm Hg, and respiratory rate 22 breaths/min. The client's admission vital signs were: heart rate 78 beats/min, blood pressure 134/82 mm Hg, and respiratory rate 16 breaths/min. The client appears restless and reports abdominal cramping. Which action should the PN take first?

Show answer & explanation

Answer: Notify the registered nurse (RN) about the changes in the client's condition.

Answer

The correct action is to notify the registered nurse (RN) about the changes in the client's condition.
The client is exhibiting early, compensatory signs of hypovolemic shock due to significant blood and fluid loss from the ulcerative colitis exacerbation. The increased heart rate, dropping blood pressure, and new-onset restlessness (indicating decreased cerebral perfusion) require immediate medical intervention. Within the practical nurse (PN) scope of practice, recognizing acute decompensation and immediately notifying the registered nurse (RN) is the highest priority action to ensure life-saving treatments are initiated promptly.

Step-by-Step Solution

1
Analyze the client's current vital signs and compare them to the admission baseline.
The heart rate has increased significantly (from 78 to 112 beats/min), blood pressure has dropped (from 134/82 to 106/68 mm Hg), and the client is restless.
Identifying trends in vital signs is crucial for detecting physiological decompensation early.
2
Correlate the assessment findings with the client's clinical presentation.
The history of large, bloody bowel movements combined with tachycardia, relative hypotension, and restlessness indicates acute fluid volume deficit and impending hypovolemic shock.
Understanding the cause of the vital sign changes guides appropriate prioritization and intervention.
3
Determine the highest priority nursing action based on the Airway, Breathing, and Circulation (ABC) framework and the PN scope of practice.
The priority is to address the circulatory compromise by immediately notifying the RN, who can initiate intravenous fluid resuscitation and contact the healthcare provider.
Escalating a critical change in condition ensures the client receives timely, life-saving interventions.

During the afternoon shift, the PN discovers the resident is unusually restless, picking at their clothing, and breathing at a rate of 26 breaths/min. Which actions should the PN prioritize? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Measure the resident's blood pressure, heart rate, and peripheral oxygenation.; Evaluate the resident's capillary refill time and extremity skin temperature.; Contact the facility charge nurse to report the sudden change in condition.

Answer

The correct actions involve prioritizing Airway, Breathing, and Circulation (ABC) data collection and escalating the findings. The PN should measure blood pressure, heart rate, and oxygenation, evaluate capillary refill and skin temperature, and immediately contact the charge nurse.
In an older adult with a localized infection, new-onset restlessness, confusion, and tachypnea are early warning signs of physiological decompensation, such as sepsis or hypoxia. The practical nurse must prioritize data collection related to Airway, Breathing, and Circulation (ABCs) by measuring oxygen saturation, blood pressure, heart rate, and peripheral perfusion (capillary refill, skin temperature). Because these findings suggest a critical shift in the client's status, immediate escalation to the supervising nurse is required to initiate prompt medical intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The new onset of restlessness and tachypnea (26 breaths/min) in a client with an active infection points toward systemic physiological compromise, such as early sepsis or hypoxia.
Recognizing acute changes from baseline is the foundation of clinical judgment and physiological adaptation.
2
Prioritize nursing interventions using the ABC framework.
Collecting comprehensive circulatory and respiratory data (blood pressure, oxygenation, capillary refill) takes precedence over routine comfort care.
Rapid identification of hemodynamic instability is essential for client survival and dictates immediate priorities.
3
Determine the appropriate scope of practice and next steps.
The PN must report these critical findings to the supervising registered nurse (RN) or provider.
Systemic physiological decompensation requires RN-level assessment and rapid provider-level medical orders.

Show answer & explanation

Answer: Measure the client's current vital signs and oxygen saturation

Answer

Measure the client's current vital signs and oxygen saturation
The correct answer addresses the immediate need to evaluate physiological stability. An acute change in mental status, such as sudden agitation and disorientation, is a primary indicator of a severe physiological complication like hypoxia, hypoglycemia, or sepsis. The practical nurse must immediately gather objective data (vital signs and oxygen saturation) to identify the underlying physiological cause before notifying the registered nurse or provider.

Step-by-Step Solution

1
Analyze the clinical scenario
The client has experienced a sudden, acute change in mental status (agitation and disorientation) compared to their baseline.
Recognizing a sudden change in condition is the first step in clinical judgment.
2
Determine the potential underlying cause
Acute confusion (delirium) in a client with an infection often indicates systemic compromise, such as hypoxia, sepsis, or fluid imbalance.
Linking the symptom to potential physiological complications guides prioritization.
3
Select the highest priority nursing action
Obtaining vital signs and oxygen saturation must be done immediately.
According to the nursing process and ABC prioritization, objective physiological data must be collected first to ensure airway, breathing, and circulation are stable before implementing other interventions.

Question 14Question →

While working in a skilled nursing facility, a practical nurse receives a report from an assistive personnel regarding an older adult resident with a healing stage 3 sacral pressure injury. The resident is described as unusually difficult to awaken and suddenly disoriented to place. Current vital signs reveal a blood pressure of 94/58 mmHg, a heart rate of 114 beats/min, a respiratory rate of 24 breaths/min, and a tympanic temperature of 96.2°F (35.7°C). Based on these assessment data, what is the most appropriate initial action for the practical nurse to take?

Show answer & explanation

Answer: Communicate the clinical changes to the supervising registered nurse for urgent evaluation.

Answer

Communicate the clinical changes to the supervising registered nurse for urgent evaluation.
The client's presentation of sudden confusion, hypothermia, tachycardia, and borderline hypotension strongly suggests the onset of sepsis, likely originating from the sacral pressure injury. In older adults, infection often presents atypically with hypothermia and altered mental status rather than a fever. Because these vital signs indicate impending hemodynamic instability and distributive shock, the practical nurse must prioritize communicating these changes to the supervising registered nurse immediately to initiate life-saving interventions.

Step-by-Step Solution

1
Analyze the client's current clinical presentation and vital signs.
The resident exhibits sudden confusion, hypothermia (96.2°F), tachycardia (114 beats/min), tachypnea (24 breaths/min), and borderline hypotension (94/58 mmHg).
Identifying abnormal data is the first step in recognizing a change in client condition.
2
Correlate the physical findings with the client's medical history.
The presence of a stage 3 sacral pressure injury provides a high-risk source for systemic infection. The combined signs strongly suggest systemic inflammatory response syndrome (SIRS) or septic shock.
Older adults frequently present with atypical signs of infection, such as hypothermia and acute delirium, rather than classic high fevers.
3
Determine the priority nursing intervention within the practical nurse scope of practice.
The client is experiencing a life-threatening acute decompensation that requires advanced hemodynamic support and medical orders.
The practical nurse must recognize the instability and immediately escalate the findings to the supervising registered nurse or provider for urgent intervention.

Question 15Question →

A practical nurse is caring for a client who had a cardiac catheterization through the right femoral artery 6 hours ago. The client reports a new, continuous lower backache. During data collection, the nurse notes the right pedal pulse is palpable but weaker than the left, a heart rate of 104 beats per minute, and a blood pressure of 102/60 mm Hg. What is the priority action for the practical nurse?

Show answer & explanation

Answer: Alert the registered nurse immediately about the client's changing condition.

Answer

The correct action is to alert the registered nurse immediately about the client's changing condition.
The client is exhibiting classic signs of retroperitoneal bleeding, a severe complication of a femoral artery cardiac catheterization. The new onset of continuous backache occurs because blood is accumulating in the retroperitoneal space, causing pressure. The diminished distal pulse and borderline vital signs (tachycardia and mild hypotension) indicate early hemorrhagic shock. The practical nurse must immediately escalate this critical circulatory emergency to the registered nurse for rapid medical intervention.

Step-by-Step Solution

1
Analyze the client's procedure and current symptoms.
The client had a right femoral cardiac catheterization and now presents with new back pain, a weaker distal pulse, and borderline tachycardia and hypotension.
Identifying the combination of symptoms following this specific invasive procedure is crucial for recognizing early complications.
2
Correlate the clinical findings with potential postoperative complications.
These findings strongly indicate retroperitoneal bleeding.
Blood pooling in the retroperitoneal space causes referred back pain, while active volume loss leads to a compensatory increase in heart rate and a drop in blood pressure.
3
Determine the priority nursing action based on the practical nurse scope of practice.
The nurse must immediately escalate the findings to the registered nurse or provider.
A retroperitoneal hemorrhage is a critical circulatory emergency that requires immediate medical intervention and fluid resuscitation beyond the independent scope of a practical nurse.

A practical nurse is reviewing morning laboratory results for an adult client with a history of heart failure who is receiving a daily loop diuretic. The client's serum potassium level is 2.8 mEq/L (2.8 mmol/L). Which action should the nurse take first?

Show answer & explanation

Answer: Promptly notify the registered nurse and the healthcare provider about the laboratory result.

Answer

Promptly notify the registered nurse and the healthcare provider about the laboratory result.
The correct answer addresses the urgent need to report a critically low serum potassium level. Normal serum potassium ranges from 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Severe hypokalemia can lead to life-threatening cardiac dysrhythmias. Immediate escalation ensures that the client receives prompt medical intervention, such as intravenous potassium replacement and the temporary discontinuation of the potassium-wasting diuretic.

Step-by-Step Solution

1
Identify the normal reference range for serum potassium.
The expected normal range is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L).
This establishes a baseline to evaluate the significance of the client's laboratory results.
2
Evaluate the client's specific laboratory value.
A value of 2.8 mEq/L (2.8 mmol/L) indicates severe hypokalemia.
Loop diuretics commonly cause potassium wasting, leading to this expected but dangerous imbalance.
3
Determine the priority nursing intervention based on the practical nurse's scope of practice.
The nurse must immediately escalate this critical finding to the registered nurse or healthcare provider.
Severe hypokalemia can cause fatal cardiac dysrhythmias, making this a time-sensitive physiological emergency that requires immediate medical intervention.

An 82-year-old client is recovering on the medical-surgical unit two days after a bowel resection. Upon entering the room, the practical nurse observes that the client is newly restless, confused about their location, and has a heart rate of 118 beats per minute with a blood pressure of 92/56 mm Hg. The client also points to their abdomen and moans in pain. Which action should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the mental status change and vital signs.

Answer

Notify the registered nurse immediately regarding the mental status change and vital signs.
The client is exhibiting signs of physiological instability, including tachycardia, hypotension, and new-onset confusion. These findings strongly suggest poor tissue perfusion or early shock. According to the ABCs (Airway, Breathing, Circulation) of prioritization, addressing acute circulatory compromise takes precedence over other interventions. The practical nurse must immediately report these acute changes to the registered nurse so prompt, life-saving medical treatment can be initiated.

Step-by-Step Solution

1
Analyze the client's new data, including new-onset confusion, tachycardia (118 bpm), and hypotension (92/56 mm Hg).
These findings are indicators of impaired physiological adaptation, specifically poor tissue perfusion or early shock.
Identifying acute, systemic changes in circulation and oxygenation is the critical first step in clinical judgment.
2

A client is receiving care in a rehabilitation facility three days after a surgical repair of a fractured femur. The client activates the call light, requesting assistance to use the bedside commode, and mentions feeling unusually weak and slightly dizzy. The practical nurse checks the client's vital signs and notes a heart rate of 114 beats per minute, a respiratory rate of 24 breaths per minute, and a blood pressure of 98/62 mmHg. The client's baseline blood pressure from the previous shift was 138/86 mmHg with a heart rate of 78 beats per minute. Which action is the most appropriate for the practical nurse to take next?

Show answer & explanation

Answer: Instruct the client to remain in bed and immediately communicate the assessment findings to the supervising registered nurse.

Answer

The practical nurse should instruct the client to remain in bed and immediately communicate the assessment findings to the supervising registered nurse.
The correct response addresses both client safety and the need for rapid escalation. A significant drop in blood pressure paired with tachycardia in a postoperative client strongly suggests hypovolemia or hemorrhage. By keeping the client in bed, the PN prevents a potential fall and preserves cerebral perfusion, while notifying the RN ensures the client receives prompt medical intervention.

Step-by-Step Solution

1
Analyze the client's current vital signs compared to their baseline data.
The heart rate has increased from 78 to 114 beats per minute, and the blood pressure has dropped from 138/86 to 98/62 mmHg.
Identifying significant deviations from baseline is crucial for recognizing physiological deterioration.
2
Synthesize the vital sign changes with the clinical context (post-femur repair, dizziness, weakness).
The findings point toward hemodynamic instability, such as hypovolemic shock or concealed hemorrhage, rather than benign dizziness.
Orthopedic surgeries carry a high risk for significant blood loss and fluid shifts.
3
Determine the priority action within the practical nursing scope of practice.
The PN must ensure client safety by preventing movement (which could worsen hypotension) and escalate the critical data to the RN.
Acute physiological decompensation requires rapid intervention and falls outside the scope of independent PN management.

A client who sustained a complex pelvic fracture in a motor vehicle collision is being monitored on the trauma step-down unit. Four hours after admission, the client is awake, reports pelvic pain rated 5 on a 0-10 scale, and complains of intense thirst. The practical nurse collects the current vital signs: blood pressure 106/80 mm Hg, heart rate 118 beats/min, respiratory rate 22 breaths/min, and a capillary refill time of 4 seconds. The admission blood pressure was 126/74 mm Hg with a heart rate of 86 beats/min. Based on this clinical picture, which action should the practical nurse prioritize?

Show answer & explanation

Answer: Withhold all oral intake and promptly communicate the assessment findings to the supervising registered nurse

Answer

The practical nurse must keep the client NPO (nothing by mouth) and immediately escalate the assessment findings to the registered nurse.
The correct answer acknowledges that the client is exhibiting classic signs of early, compensatory hypovolemic shock due to massive internal bleeding commonly associated with pelvic fractures. Intense thirst, tachycardia, a narrowed pulse pressure (the difference between systolic and diastolic pressures), and delayed capillary refill all indicate severe intravascular volume loss. Withholding oral fluids protects the airway if emergency surgery is needed, and immediate escalation is required for lifesaving interventions.

Step-by-Step Solution

1
Analyze the vital sign trends compared to the admission baseline.
The heart rate increased from 86 to 118 bpm, the pulse pressure narrowed significantly (from 52 to 26 mm Hg), and capillary refill is delayed (4 seconds).
Identifying deviations from baseline is critical for recognizing early physiological decompensation.
2
Correlate the vital signs with the client's injury and symptoms.
Pelvic fractures carry a high risk of massive hidden hemorrhage. The combination of tachycardia, narrowed pulse pressure, delayed perfusion, and intense thirst strongly indicates early compensatory shock.
Understanding the underlying pathophysiology of the specific injury guides clinical judgment.
3
Determine the safest and most appropriate scope-compliant intervention.
The priority is to anticipate the need for surgical intervention (requiring NPO status) and alert the RN or provider to initiate aggressive resuscitation.
The practical nurse must recognize life-threatening complications and escalate care while maintaining patient safety.

A practical nurse (PN) is caring for a client with a T4 spinal cord injury. The client suddenly reports a severe, pounding headache. The PN observes profuse diaphoresis above the level of the injury and records a blood pressure of 210/110 mm Hg. 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: 1) Elevate the head of the bed, 2) Examine the urinary catheter, 3) Contact the registered nurse (RN), and 4) Document the findings.
Autonomic dysreflexia is a medical emergency characterized by severe hypertension and a pounding headache in clients with spinal cord injuries above T6. The first action is always to elevate the head of the bed to use orthostatic pressure changes to lower the blood pressure. Next, the PN must search for and resolve the trigger, which is most often a distended bladder caused by a kinked catheter. After taking these immediate independent bedside actions, the PN must notify the RN. Finally, the event and interventions should be documented once the client is safe.

Step-by-Step Solution

1
Elevate the head of the bed to a high-Fowler's position.
The client's upper body is raised, promoting orthostatic changes.
This immediately helps to lower the dangerously high blood pressure and decreases the risk of cerebral hemorrhage before any other action is taken.
2
Examine the indwelling urinary catheter system for kinks or obstructions.
The source of the autonomic dysreflexia trigger is identified and potentially resolved.
Bladder distention is the most common noxious stimulus causing autonomic dysreflexia; removing the stimulus halts the sympathetic nervous system surge.
3
Contact the registered nurse (RN) to report the abnormal findings.
The supervising nurse is informed of the acute change in status.
The RN or healthcare provider must be notified to evaluate the client, adjust the plan of care, or administer prescribed antihypertensive medications if the blood pressure does not resolve.
4
Document the client's vital signs and the sequence of events.
A legal and clinical record of the emergency and interventions is created.
Documentation is completed after the client is stabilized and the healthcare team is notified.
