Record the assessment data and plan to recheck the measurements in one hour

Provide the prescribed as-needed antiemetic to address the client's mild nausea

Independently increase the maintenance intravenous fluid rate to raise the blood pressure

Show answer & explanation

Answer: Alert the charge nurse about the current vital signs immediately

Answer

Alert the charge nurse about the current vital signs immediately.

The correct action is to immediately notify the supervising nurse. The client's tachycardia (116 beats/minute) and drop in blood pressure from the baseline are early clinical indicators of hypovolemic shock, likely due to postoperative hemorrhage. The practical nurse must recognize this critical change and rapidly escalate the findings to ensure immediate intervention.

Step-by-Step Solution

Analyze the client's postoperative vital signs against baseline parameters.

The heart rate is elevated at 116 beats/minute, and the blood pressure has decreased significantly from 122/76 mm Hg to 92/56 mm Hg.

Identifying trends in vital signs is essential for recognizing early complications.

Determine the clinical significance of these findings.

Tachycardia combined with hypotension in a postoperative client strongly suggests hypovolemia or internal hemorrhage.

Changes in circulating blood volume trigger compensatory mechanisms, such as an increased heart rate, before cardiovascular collapse occurs.

Select the appropriate nursing intervention based on scope of practice.

The practical nurse must immediately report these critical findings to the charge nurse or registered nurse for further assessment and intervention.

Escalating deteriorating client conditions ensures timely medical management and reduces the potential for risk or severe injury.

A practical nurse (PN) is prioritizing care for a client who is 6 hours postoperative following a partial bowel resection. The PN reviews the client's current assessment data and laboratory results. Which of the following findings indicate a potential complication requiring immediate escalation to the registered nurse (RN)? Select all that apply.

Select all that apply

Heart rate of 118 beats/min and blood pressure of 90/58 mm Hg

Serum potassium level of 2.8 mEq/L (2.8 mmol/L)

Total urine output of 45 mL over the past 3 hours

Absent bowel sounds in all four abdominal quadrants

Temperature of 99.2°F (37.3°C) and respiratory rate of 18 breaths/min

Incisional pain rated as 5 on a 0 to 10 scale

Show answer & explanation

Answer: Heart rate of 118 beats/min and blood pressure of 90/58 mm Hg; Serum potassium level of 2.8 mEq/L (2.8 mmol/L); Total urine output of 45 mL over the past 3 hours

Answer

The findings requiring immediate escalation are the elevated heart rate with hypotension, the critically low serum potassium level, and the decreased total urine output over the past 3 hours.

The correct findings requiring immediate escalation include the elevated heart rate combined with hypotension, the critically low potassium level, and the oliguria. Tachycardia and hypotension are early systemic indicators of hypovolemic shock or internal hemorrhage. A serum potassium of 2.8 mEq/L is critically low and places the client at immediate risk for life-threatening cardiac dysrhythmias. Furthermore, a total urine output of 45 mL over 3 hours equates to 15 mL/hr, which is well below the minimum expected 30 mL/hr threshold and indicates significantly compromised renal perfusion or fluid volume deficit.

Step-by-Step Solution

Analyze the vital signs for indications of systemic instability.

The heart rate of 118 beats/min and blood pressure of 90/58 mm Hg indicate potential hypovolemic shock. The temperature of 99.2°F and respiratory rate of 18 are expected normal post-op findings.

Prioritizing Airway, Breathing, and Circulation (ABC) is essential to identify life-threatening hemorrhage or fluid volume deficit.

Evaluate the laboratory results against normal reference ranges.

The potassium level of 2.8 mEq/L is significantly below the normal range of 3.5-5.0 mEq/L.

Hypokalemia can cause fatal cardiac dysrhythmias and requires prompt potassium replacement and cardiac monitoring.

Assess the genitourinary and gastrointestinal findings for post-operative complications.

Urine output is 15 mL/hr (below the 30 mL/hr minimum), indicating poor perfusion. Absent bowel sounds are expected after bowel surgery.

Differentiating expected physiological adaptations from signs of organ hypoperfusion ensures appropriate clinical escalation.

Key Concept

Recognizing and prioritizing early signs of postoperative complications (shock, hypokalemia, and oliguria) over expected physiological findings.

Question 1283Question →

A practical nurse (PN) is caring for a client with a spinal cord injury at the T4 level. The client suddenly reports a severe, pounding headache and blurred vision. The PN observes profuse diaphoresis and flushing above the level of the injury. Arrange the following actions in the order the PN should perform them, from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions is: 1) Elevate the head of the bed to a sitting or high-Fowler's position; 2) Measure the client's blood pressure to confirm hypertension; 3) Assess the client's indwelling urinary catheter for kinks or blockages; 4) Notify the registered nurse (RN) or healthcare provider of the client's condition.

The client is exhibiting classic signs of autonomic dysreflexia, a medical emergency in clients with spinal cord injuries above T6. The immediate priority is to lower the blood pressure by utilizing orthostatic changes (elevating the head of the bed). Once repositioned, the blood pressure must be measured to confirm the hypertensive crisis. Next, the PN should assess for and remove the most common triggering stimulus, which is typically bladder distention from a blocked catheter. Finally, the RN must be notified to collaborate on further management and potential pharmacological interventions.

Step-by-Step Solution

Recognize the clinical signs of autonomic dysreflexia.

The combination of a T4 spinal cord injury, severe pounding headache, blurred vision, and flushing/diaphoresis indicates a life-threatening hypertensive emergency.

Identifying the condition immediately is critical for selecting the appropriate, time-sensitive interventions.

Prioritize interventions based on the immediate threat to life.

Elevating the head of the bed is identified as the first and most critical action.

This utilizes orthostatic changes to rapidly lower blood pressure, mitigating the imminent risk of an intracranial hemorrhage.

Determine the sequence of subsequent data collection and source identification.

The blood pressure is measured to confirm the crisis, followed by assessing the catheter.

Objective data must be gathered to confirm the crisis, and then the most common noxious stimulus (bladder distention) must be addressed to halt the dysreflexia.

Determine the final step of escalation.

Notifying the RN or provider is the final immediate action.

Collaboration is necessary for ongoing management and to initiate potential pharmacological treatments if removing the stimulus is insufficient.

Instruct the client to tilt their chin downward toward their chest when swallowing.

Position the head of the bed at a 45-degree angle during the meal.

Place each spoonful of food into the right side of the client's mouth.

Provide a straw for the client to drink liquids between bites of solid food.

Show answer & explanation

Answer: Instruct the client to tilt their chin downward toward their chest when swallowing.

Answer

Instruct the client to tilt their chin downward toward their chest when swallowing.

The chin-tuck maneuver is a standard aspiration precaution. It narrows the airway opening and directs the food bolus toward the esophagus, significantly decreasing the risk of aspiration.

Step-by-Step Solution

Identify the client's deficits and associated risks.

The client has dysphagia and right-sided weakness, placing them at high risk for aspiration and airway compromise.

Recognizing physical limitations dictates the necessary safety interventions during oral intake.

Determine the optimal positioning and feeding techniques for aspiration precautions.

The client needs to be seated upright at 90 degrees, food must be placed on the strong side (left), and airway-protecting maneuvers like a chin-tuck should be utilized.

Gravity and anatomical positioning help direct food into the esophagus rather than the trachea.

Evaluate the provided options against established dysphagia guidelines.

The chin-tuck method correctly protects the airway, while the other options introduce significant aspiration risks.

Choosing the intervention that actively promotes airway safety is the clinical priority.

Show answer & explanation

Answer: The client reports a new, deep, and persistent ache localized in the lower back and flank.; Blood pressure is $106/58\text{ mm Hg}$ and heart rate is $118\text{ bpm}$ , compared to a pre-procedure baseline of $136/78\text{ mm Hg}$ and $82\text{ bpm}$ .; A firm, localized, and tender swelling is palpable directly beneath the pressure dressing at the right groin insertion site.

Answer

The findings requiring immediate escalation are the new onset of deep lower back/flank pain, the significant drop in blood pressure with tachycardia, and the palpable firm swelling at the insertion site.

Following a femoral artery procedure, clients are at high risk for vascular complications. A drop in blood pressure combined with tachycardia indicates hypovolemia, likely from internal bleeding. New, persistent back or flank pain is the classic presentation of a retroperitoneal hemorrhage. A firm, tender, expanding swelling at the puncture site indicates a developing hematoma. All of these are life-threatening emergencies requiring immediate manual pressure, RN notification, and provider intervention.

Step-by-Step Solution

Analyze the procedure and its associated risks.

The client underwent a femoral artery PCI, which carries high-risk potential for arterial bleeding, hematoma formation, and retroperitoneal hemorrhage.

Identifying procedure-specific risks directs the focused assessment priorities and defines what constitutes an emergency.

Evaluate each assessment finding against the expected post-operative baseline.

Back pain and dropping blood pressure indicate internal retroperitoneal bleeding. A firm mass indicates a local hematoma. A low-grade temperature, dry drainage, and muscle stiffness are expected, benign findings.

Discriminating between expected post-procedure recovery symptoms and emergent, life-threatening complications is critical for appropriate risk reduction and timely RN escalation.

Question 1286Question →

An adult client is prescribed a daily dose of oral diltiazem for the management of hypertension. Prior to providing the morning dose, the practical nurse (PN) obtains a blood pressure reading of $88/54$ mm Hg and an apical heart rate of $58$ beats/min. Which of the following actions should the PN perform?

Instruct a nursing assistant to repeat the blood pressure measurement in thirty minutes.

Provide the medication as prescribed and record the physiological data in the client's health record.

Pause the administration and alert the registered nurse regarding the client's current vital signs.

Place the tablet on the bedside table and advise the client to take it once they feel less dizzy.

Show answer & explanation

Answer: Pause the administration and alert the registered nurse regarding the client's current vital signs.

Answer

The most appropriate action is to pause the administration and notify the registered nurse about the low blood pressure and heart rate.

The correct action is to pause the administration and alert the registered nurse. Diltiazem is a calcium channel blocker that decreases heart rate and blood pressure. Because the client is currently hypotensive (

88/54

mm Hg) and bradycardic (

58

beats/min), giving the medication could lead to severe, life-threatening cardiovascular depression. The practical nurse must prioritize client safety by holding the medication and promptly reporting the abnormal findings to the supervising registered nurse for further clinical decision-making.

Step-by-Step Solution

Analyze the current vital signs against the anticipated effects of the prescribed medication.

The blood pressure of

88/54

mm Hg is low (hypotension), and the heart rate of

58

beats/min is low (bradycardia). Diltiazem lowers both of these parameters.

Understanding the pharmacodynamics of a drug is essential before administration to prevent adverse outcomes.

Determine if the medication is safe to give under the current clinical conditions.

It is unsafe to administer the diltiazem because it will exacerbate the client's existing hypotension and bradycardia.

Client safety dictates that medications with depressive effects on the cardiovascular system must be held if baseline parameters are too low.

Select the nursing action that aligns with the practical nurse (PN) scope of practice.

The PN must withhold the medication and escalate the critical findings to the registered nurse for further medical evaluation.

The PN is responsible for recognizing abnormal findings, ensuring immediate safety by holding the drug, and collaborating with the RN for advanced assessment.

Question 1287Question →

The practical nurse (PN) is assisting a healthcare provider with a lumbar puncture for an adult client on the medical-surgical unit. In what order should the PN perform the following actions to ensure client safety and reduce the risk of complications? Arrange the actions in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Obtain baseline vital signs, assist the client into a fetal position, support the client during insertion, apply a sterile dressing, and instruct the client to maintain a flat supine position.

Assisting with a lumbar puncture requires a strict chronological approach to reduce risk. First, baseline data must be collected to allow for accurate post-procedure monitoring. Next, the client is placed in the fetal position to optimally open the intervertebral spaces. During the procedure, the nurse's role is to ensure the client remains completely still to prevent injury. Following needle removal, the site must immediately be covered with a sterile dressing to prevent infection. Finally, placing the client in a flat, supine position reduces the risk of a spinal headache caused by cerebrospinal fluid leakage.

Step-by-Step Solution

Obtain the client's baseline vital signs and perform a focused neurological check.

Baseline clinical data is documented prior to the procedure.

Provides a baseline to compare against post-procedure assessments for early detection of complications.

Assist the client into a side-lying position with the knees pulled toward the chest.

The client's spine is flexed, opening the intervertebral spaces.

This physical position allows the healthcare provider optimal access to the subarachnoid space and reduces the risk of trauma.

Support the client and provide reminders to remain still during the needle insertion.

The client remains completely still during the most critical phase.

Sudden movements can cause the needle to damage surrounding tissues, nerves, or the spinal cord.

Place a sterile dressing over the puncture site once the needle is withdrawn.

The puncture site is securely covered.

Maintains a sterile barrier to prevent infection from entering the central nervous system.

Instruct the client to maintain a flat, supine position for the prescribed duration.

The client lies flat in bed for several hours.

Reduces hydrostatic pressure on the puncture site, preventing cerebrospinal fluid (CSF) leakage and post-lumbar puncture headache.

Two hours following the procedure, the practical nurse records a blood pressure of 94/56 mmHg and a resting heart rate of 118 beats per minute. The client's pre-procedure baseline demonstrated a blood pressure of 134/82 mmHg and a heart rate of 74 beats per minute. Based on these findings, which action must the nurse take first?

Assist the client into a high Fowler's position to promote optimal lung expansion and comfort.

Document the vital signs in the chart as an anticipated physiological response to the fluid removal.

Promptly report the altered vital signs to the supervising registered nurse for further evaluation.

Independently initiate a rapid intravenous fluid bolus of normal saline to restore vascular volume.

Show answer & explanation

Answer: Promptly report the altered vital signs to the supervising registered nurse for further evaluation.

Answer

The correct action is to promptly report the altered vital signs to the supervising registered nurse for further evaluation.

The client is exhibiting tachycardia and hypotension, which are early signs of hypovolemic shock due to rapid intravascular fluid shifts following a large-volume paracentesis. The most appropriate and immediate action within the practical nurse scope of practice is to communicate these unstable hemodynamic changes to the supervising registered nurse to ensure advanced assessment and treatment are rapidly initiated.

Step-by-Step Solution

Compare the client's current post-procedure vital signs to the pre-procedure baseline.

The blood pressure dropped significantly from 134/82 mmHg to 94/56 mmHg, and the heart rate increased from 74 to 118 beats per minute.

Identifying significant trends in vital signs is essential to recognize early postoperative complications.

Interpret the clinical significance of these sudden hemodynamic changes.

The findings of hypotension and tachycardia indicate a potential intravascular fluid shift or bleeding, which are early signs of hypovolemic shock.

Removal of a large amount of ascitic fluid during a paracentesis can cause rapid intravascular fluid shifts and decreased circulating volume.

Determine the priority nursing intervention within the practical nurse scope of practice.

The priority is to immediately escalate the critical findings to the registered nurse or healthcare provider.

The practical nurse must promptly report signs of hemodynamic instability so that advanced assessment and medical interventions can be initiated safely.

Apply a bed alarm and request an order for physical restraints.

Obtain a pulse oximetry reading and assess the client's respiratory effort.

Show answer & explanation

Answer: Obtain a pulse oximetry reading and assess the client's respiratory effort.

Answer

Obtain a pulse oximetry reading and assess the client's respiratory effort.

Sudden onset of agitation and disorganized thinking in a client with a respiratory illness is a classic early sign of hypoxia. Using the ABC (Airway, Breathing, Circulation) framework, the nurse must first assess the client's respiratory status and tissue oxygenation before assuming the behavior is strictly psychological or age-related.

Step-by-Step Solution

Identify the acute change in the client's condition.

The client has transitioned from alert and cooperative to agitated, confused, and unsafe.

Sudden mental status changes in older adults require immediate investigation to rule out life-threatening physiological causes.

Relate the client's underlying diagnosis to potential complications.

The client has severe pneumonia, which significantly impairs gas exchange and creates a high risk for hypoxia.

Hypoxia frequently manifests as restlessness, anxiety, agitation, and confusion, particularly before cyanosis or other late signs appear.

Prioritize nursing actions based on the ABC (Airway, Breathing, Circulation) framework.

Airway and breathing assessments must take precedence over psychosocial interventions or safety restraints.

Evaluating oxygen saturation and respiratory effort directly addresses the most likely and most critical physiological cause of the sudden agitation.

Accept a verbal order from the provider to independently administer an intravenous push of naloxone to reverse the sedation.

Prepare the oral dose and verify the client's identity using the bed assignment and room number to avoid delaying treatment.

Show answer & explanation

Answer: Withhold the opioid medication and immediately notify the registered nurse about the client's respiratory depression.

Answer

The nurse must withhold the opioid medication and immediately alert the registered nurse regarding the client's compromised respiratory status.

The client is exhibiting signs of severe central nervous system and respiratory depression, evidenced by a respiratory rate of 8 breaths per minute and difficulty arousing. These are critical adverse effects of opioid analgesics. The absolute priority for the practical nurse is to ensure client safety by utilizing the ABC (Airway, Breathing, Circulation) framework. This requires withholding any further central nervous system depressants and immediately escalating the findings to the registered nurse or healthcare provider for rapid medical intervention.

Step-by-Step Solution

Assess the client's clinical presentation in relation to the requested medication.

The client has a severely depressed respiratory rate (8 breaths per minute) and altered level of consciousness (difficult to arouse).

Before administering any central nervous system depressant like hydromorphone, the nurse must ensure the client's vital signs can safely tolerate the medication.

Prioritize the clinical findings using the Airway, Breathing, Circulation (ABC) framework.

The compromised breathing status takes immediate precedence over the client's severe pain report.

Airway and breathing are fundamental physiological needs; failure to maintain them can lead to rapid deterioration and respiratory arrest.

Determine the safest and most appropriate intervention within the practical nursing scope of practice.

The nurse withholds the scheduled medication and immediately notifies the registered nurse.

The practical nurse must prevent further harm by withholding the drug and escalating the situation to the RN, who has the scope to administer intravenous push reversal agents if ordered.

Question 1291Question →

A practical nurse (PN) enters the room of a client receiving a continuous enteral tube feeding. The client is coughing forcefully, appears dyspneic, and is clutching their chest. 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: Stop the continuous enteral feeding pump, elevate the head of the bed to a high-Fowler's position, obtain the client's oxygen saturation and respiratory rate, notify the registered nurse (RN) of the client's status, and then gather equipment for potential oropharyngeal suctioning.

In any clinical emergency, the nurse must prioritize actions using the Airway, Breathing, Circulation (ABC) framework and the nursing process. The absolute first step is to stop the continuous feeding to eliminate the immediate risk of further aspiration (Airway). Second, positioning the client in a high-Fowler's position maximizes lung expansion (Breathing). Third, the nurse assesses the client's respiratory status to gather objective data. Fourth, the nurse reports these findings to the RN for escalation of care. Finally, the nurse anticipates further needs by gathering suction equipment.

Step-by-Step Solution

Stop the continuous enteral feeding pump.

The flow of enteral formula is halted immediately.

According to the airway, breathing, circulation (ABC) framework, removing the immediate threat to the airway (potential aspiration of formula) is the absolute highest priority.

Elevate the head of the bed to a high-Fowler's position.

The client's chest cavity is optimized for expansion.

An upright position lowers the diaphragm, promotes maximum chest expansion, and uses gravity to prevent further reflux of gastric contents into the airway.

Obtain the client's oxygen saturation and respiratory rate.

Focused respiratory data is collected.

After addressing the immediate physical threat, the nurse must assess the client's physiological response to determine the degree of respiratory compromise.

Notify the registered nurse (RN) of the client's status.

The supervising nurse is informed of the acute change in condition.

The PN must communicate the objective data and client presentation to the RN, who will coordinate with the healthcare provider for potential medical interventions.

Gather equipment for potential oropharyngeal suctioning.

Suction equipment is ready at the bedside.

Anticipating the need to clear secretions or formula from the upper airway ensures preparedness for the next potential intervention.

A practical nurse is preparing to administer a scheduled dose of cefazolin $750\text{ mg}$ intramuscularly (IM) to a client with a skin infection. The medication is supplied as a $1\text{ gram}$ vial of dry powder. The reconstitution instructions on the vial state: "Add $2.5\text{ mL}$ of sterile water for injection to yield a final concentration of $330\text{ mg/mL}$ ."

How many $\text{mL}$ should the nurse administer? Record the answer to the nearest tenth. Do not include units in the answer.

Show answer & explanation

Answer: 2.3

Answer

2.3

The correct volume is found by dividing the desired dose (

750\text{ mg}

) by the available concentration (

330\text{ mg}

per

1\text{ mL}

), which equals

2.2727... \text{ mL}

. Rounded to the nearest tenth, this is

2.3\text{ mL}

. Note that the

1\text{ gram}

total powder amount and the

2.5\text{ mL}

diluent volume are distractors and should not be used in the final equation once the final concentration is known.

Step-by-Step Solution

Identify the target dose and available concentration from the provided instructions.

Target dose:

750\text{ mg}

, Concentration:

330\text{ mg/mL}

These are the essential values needed to calculate the physical volume to be administered.

Apply the standard dosage calculation formula:

\frac{\text{Desired}}{\text{Have}} \times \text{Volume}

\frac{750\text{ mg}}{330\text{ mg}} \times 1\text{ mL} = 2.2727... \text{ mL}

This formula converts the prescribed medication mass into the correct physical volume based on the reconstituted concentration.

Round the calculated volume to the nearest tenth as instructed.

2.2727... \text{ mL}

rounds to

2.3\text{ mL}

Standard rounding rules dictate that a hundredths digit of

Question 1293Question →

A practical nurse (PN) is caring for a client with a T4 spinal cord injury. The client suddenly reports a severe, pounding headache and nasal congestion. The PN observes profuse sweating above the level of the spinal injury. Arrange the following nursing actions in the priority order the PN should perform them.

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, followed by measuring the blood pressure, inspecting the urinary catheter, and finally notifying the registered nurse.

Autonomic dysreflexia is a medical emergency characterized by severe hypertension. The absolute first action must be to elevate the head of the bed, which takes seconds and uses gravity to lower blood pressure, preventing a stroke. Next, the PN must obtain a blood pressure reading to confirm the crisis. Once confirmed, the PN should look for the most common cause, which is a distended bladder, by checking the catheter. Finally, the RN is notified to report the event, current vital signs, and seek potential pharmacological interventions.

Step-by-Step Solution

Elevate the head of the bed to a sitting or high-Fowler's position.

The client is positioned upright.

Gravity immediately causes orthostatic hypotension, which helps safely lower the dangerously high blood pressure and reduces the immediate risk of a cerebrovascular accident (stroke).

Measure the client's blood pressure.

Objective vital sign data is obtained.

Checking the blood pressure confirms the severity of the suspected autonomic dysreflexia and provides a baseline to determine if subsequent interventions are effective.

Inspect the urinary catheter tubing for kinks or blockages.

A potential noxious stimulus (bladder distention) is investigated and resolved if found.

Autonomic dysreflexia is triggered by an uninhibited sympathetic response to a noxious stimulus below the level of the injury. A blocked catheter is the most frequent culprit and can be fixed immediately at the bedside.

Notify the registered nurse (RN) of the client's status.

The healthcare team is alerted to the medical emergency.

The RN needs the vital signs and assessment findings to coordinate further care, which may include administering emergency antihypertensive medications if relieving the physical stimulus is ineffective.

Question 1294Question →

A practical nurse is preparing a combined subcutaneous injection of regular insulin and NPH insulin for a client whose pre-meal capillary blood glucose level is 185 mg/dL. To ensure safe medication preparation and avoid cross-contamination, arrange the following steps in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to roll the NPH vial, inject air into the NPH vial, inject air into the regular vial, withdraw the regular insulin, and finally withdraw the NPH insulin.

When mixing insulins, the standard safety protocol is 'clear before cloudy' (regular insulin before NPH insulin). This ensures that the short-acting, clear insulin is not contaminated by the intermediate-acting, cloudy insulin. The precise preparation sequence involves injecting air into the NPH vial first, then injecting air into the regular vial, drawing up the regular insulin, and finally drawing up the NPH insulin.

Step-by-Step Solution

Roll NPH insulin vial

Insulin suspension is evenly mixed without bubbles.

Ensures accurate dosing of the intermediate-acting insulin.

Inject air into NPH vial

Vial pressure is equalized for future withdrawal.

Prevents vacuum formation; done first because the needle must not have regular insulin on it yet.

Inject air into regular insulin vial

Regular insulin vial pressure is equalized.

Prepares the vial for immediate fluid withdrawal.

Withdraw regular insulin

Clear insulin is drawn into the syringe first.

Drawing clear before cloudy prevents contamination of the rapid-acting insulin with the intermediate-acting insulin.

Withdraw NPH insulin

The total mixed dose is completed in the syringe.

The cloudy insulin is safely added last to complete the mixture.

Withhold the scheduled dose of warfarin and promptly notify the registered nurse.

Administer the medication as scheduled and document the INR result in the medical record.

Independently decrease the medication dose by half to reduce the risk of bleeding.

Verify the client's room number and administer the medication to ensure timely treatment.

Show answer & explanation

Answer: Withhold the scheduled dose of warfarin and promptly notify the registered nurse.

Answer

Withhold the scheduled dose of warfarin and promptly notify the registered nurse.

An INR of 4.6 is significantly above the standard therapeutic range of 2.0 to 3.0 for warfarin therapy, placing the client at a high risk for severe bleeding. The appropriate and safe nursing action, which falls strictly within the practical nurse scope of practice, is to withhold the scheduled dose and immediately escalate the critical laboratory finding to the supervising registered nurse or healthcare provider.

Step-by-Step Solution

Analyze the client's laboratory data prior to medication administration.

The client's INR is 4.6.

To determine if the anticoagulant therapy is within safe parameters.

Question 1296Question →

An assigned client is recovering on the medical-surgical unit two hours after a percutaneous liver biopsy. The client complains of new-onset right shoulder pain. The current vital signs reveal a heart rate of 104 beats/min and a blood pressure of 102/64 mm Hg, compared to a pre-procedure heart rate of 74 beats/min and a blood pressure of 126/80 mm Hg. What is the most appropriate next step for the practical nurse (PN)?

Alert the supervising charge nurse about the assessment changes.

Provide the prescribed oral analgesic to manage the reported pain.

Help the client transition into a semi-Fowler's resting position.

Document the current assessment and repeat vital signs in sixty minutes.

Show answer & explanation

Answer: Alert the supervising charge nurse about the assessment changes.

Answer

The practical nurse should immediately alert the supervising charge nurse about the assessment changes, as these findings strongly suggest internal bleeding.

The client is demonstrating early signs of hypovolemic shock due to internal hemorrhage, a known complication of a liver biopsy. The decreasing blood pressure and increasing heart rate, combined with right shoulder pain (which indicates referred pain from diaphragmatic irritation due to blood accumulation), require immediate escalation to the supervising nurse or provider for rapid intervention.

Step-by-Step Solution

Analyze the client's vital sign trends.

The heart rate increased from 74 to 104 beats/min, and blood pressure decreased from 126/80 to 102/64 mm Hg.

Comparing current vital signs to the pre-procedure baseline is essential to identify early physiological deterioration.

Evaluate the significance of the localized pain.

The client has new-onset right shoulder pain following a liver biopsy.

Blood accumulating in the abdomen can irritate the diaphragm and phrenic nerve, causing referred pain to the right shoulder.

Determine the priority nursing intervention.

The priority is to immediately escalate the findings to the supervising RN or healthcare provider.

The combination of borderline vital signs and referred pain indicates active internal hemorrhage, which is a life-threatening complication requiring immediate medical intervention beyond the PN scope of practice.

Question 1297Question →

During the afternoon shift, a client is transferred back to the surgical unit four hours after undergoing a total thyroidectomy. Which interventions must the practical nurse implement to minimize the risk of postoperative complications? Select all that apply.

Select all that apply

Maintain the client in a semi-Fowler's position while using pillows to support the head and neck.

Verify that emergency suction equipment and a tracheostomy set are immediately accessible in the room.

Inspect the posterior aspect of the client's neck and the bed linens for dependent pooling of blood.

Instruct the client to frequently hyperextend the neck to prevent cervical muscle stiffness.

Delegate the evaluation of the client's swallowing reflex to the unlicensed assistive personnel (UAP).

Administer prescribed oral pain medication before fully evaluating a new onset of respiratory stridor.

Show answer & explanation

Answer: Maintain the client in a semi-Fowler's position while using pillows to support the head and neck.; Verify that emergency suction equipment and a tracheostomy set are immediately accessible in the room.; Inspect the posterior aspect of the client's neck and the bed linens for dependent pooling of blood.

Answer

The correct interventions include maintaining the client in a semi-Fowler's position with head support, ensuring emergency airway equipment is at the bedside, and assessing the back of the neck for dependent bleeding.

Following a total thyroidectomy, clients are at significant risk for airway obstruction, hemorrhage, and hypocalcemia. Maintaining a semi-Fowler's position with the head supported minimizes tension on the suture line and reduces surgical site edema. Because airway compromise can occur rapidly from swelling or bleeding, emergency suction and a tracheostomy set must be readily available. Additionally, checking the back of the neck and linens is crucial because blood from the surgical site can pool dependently without being visible on the anterior dressing.

Step-by-Step Solution

Identify the surgical procedure and the postoperative timeframe.

The client is 4 hours post-total thyroidectomy.

The early postoperative phase carries the highest risk for acute hemorrhage and airway compromise.

Determine the priority risks associated with a thyroidectomy.

Risks include airway obstruction from laryngeal edema, acute hemorrhage, and hypocalcemia.

The anatomical location of the thyroid gland near the trachea and major blood vessels creates specific localized risks.

Evaluate each intervention against these risks and the practical nurse's scope of practice.

Positioning, emergency equipment preparation, and assessing for bleeding actively reduce risks. Neck hyperextension, UAP delegation of assessment, and ignoring airway sounds increase risks.

Appropriate nursing interventions must actively prevent complications, prioritize physiological stability, and remain within safe delegation boundaries.

Question 1298Question →

A client with liver cirrhosis and a recent history of esophageal varices is resting in a medical-surgical unit. Upon assuming care, the practical nurse notes a baseline blood pressure of 106/72 mm Hg and a heart rate of 94 beats per minute. An hour later, the client suddenly becomes restless, begins pulling at the bed linens, and has pale, diaphoretic skin. Which action should the practical nurse take first?

Administer a prescribed as-needed dose of medication for the acute agitation.

Reassess the client's blood pressure and pulse rate immediately.

Document the behavioral changes and plan to recheck vital signs at the next scheduled time.

Dim the room lights and encourage the client to practice deep breathing.

Show answer & explanation

Answer: Reassess the client's blood pressure and pulse rate immediately.

Answer

The priority action is to reassess the client's blood pressure and pulse rate immediately to evaluate for signs of hypovolemic shock.

The correct action is to immediately measure the client's vital signs. A client with a history of esophageal varices is at high risk for internal hemorrhage. Sudden restlessness, pallor, and diaphoresis, combined with an earlier borderline heart rate, are classic early signs of hypovolemic shock. The practical nurse must gather objective hemodynamic data (blood pressure and pulse) to report to the registered nurse for rapid medical intervention.

Step-by-Step Solution

Analyze the client's clinical presentation and medical history.

The client has a high risk for bleeding due to esophageal varices and is exhibiting sudden restlessness, pallor, and diaphoresis after having borderline tachycardia.

Identifying the underlying risk for hemorrhage is crucial for accurate clinical judgment and prioritization.

Evaluate the new symptoms using the Airway, Breathing, Circulation (ABC) framework.

The client's acute changes in mental status and skin condition strongly suggest compromised circulation and decreased cerebral perfusion.

Recognizing early physiological signs of hypovolemic shock ensures that life-threatening complications are addressed before secondary issues.

Select the most appropriate initial action within the practical nurse's scope of practice.

Measuring current vital signs is the immediate priority to obtain objective hemodynamic data.

Current vital signs are necessary to confirm clinical suspicions before escalating the situation to the registered nurse or healthcare provider.

Question 1299Question →

A practical nurse (PN) is walking in the hallway with a client who has a history of seizure disorders. The client suddenly loses consciousness and begins to experience tonic-clonic muscle jerking. In what order should the PN perform the following actions? Arrange the actions in order of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate physical safety, followed by airway protection, and concludes with assessment and timing.

In any acute emergency, the nurse must prioritize immediate life-saving interventions and injury prevention over assessment. Easing the falling client to the floor prevents immediate trauma. Protecting the head prevents secondary trauma from convulsions. Turning the client on their side protects the airway from aspiration. Only after these immediate physical safeguards are in place should the nurse focus on timing and observing the clinical characteristics of the seizure.

Step-by-Step Solution

Guide the client to the floor.

The client is on the ground in a controlled manner.

Prevents severe injury that would occur from a sudden drop.

Place a pad or pillow under the head.

The head is cushioned against the hard floor.

Prevents traumatic brain injury or skull fracture during rhythmic convulsions.

Turn the client onto their side.

The airway remains clear of secretions and the tongue.

Reduces the risk of aspiration and maintains airway patency.

Observe and time the seizure.

Accurate clinical data is gathered.

Provides the healthcare provider with necessary information to determine if emergency medication is required (e.g., status epilepticus).

Reinforcing teaching for a client starting sublingual nitroglycerin to sit or lie down before placing the tablet under the tongue.

Administering a scheduled live-attenuated measles, mumps, and rubella (MMR) vaccine to a pregnant client during a prenatal clinic visit.

Providing a prescribed oral sedative to a client preparing for an invasive procedure before the provider has obtained the signed consent.

Delaying the administration of prescribed warfarin and alerting the registered nurse after noting an International Normalized Ratio (INR) result of 5.8.

Proceeding to give oral furosemide to a postoperative client exhibiting new-onset mild tachycardia and a blood pressure of 86/52 mmHg.

Validating the calculation for a pediatric weight-based oral suspension with a second licensed nurse before administering the drug.

Show answer & explanation

Answer: Reinforcing teaching for a client starting sublingual nitroglycerin to sit or lie down before placing the tablet under the tongue.; Delaying the administration of prescribed warfarin and alerting the registered nurse after noting an International Normalized Ratio (INR) result of 5.8.; Validating the calculation for a pediatric weight-based oral suspension with a second licensed nurse before administering the drug.

Answer

The correct actions that demonstrate safe practice are: reinforcing the need to sit or lie down when taking sublingual nitroglycerin, delaying the warfarin dose for a critically elevated INR of 5.8 while notifying the RN, and independently validating a pediatric weight-based calculation with a second nurse.

The correct choices demonstrate adherence to crucial pharmacological safety principles: reinforcing safety measures for vasodilators to prevent falls, recognizing and responding to critical laboratory values that increase bleeding risk, and utilizing independent double-checks for high-risk pediatric dosages.

Step-by-Step Solution

Evaluate the action regarding sublingual nitroglycerin.

Teaching the client to sit or lie down is correct.

Nitroglycerin causes rapid vasodilation, increasing the risk of orthostatic hypotension and syncope.

Evaluate the action regarding the MMR vaccine in a pregnant client.

Administering this vaccine is incorrect.

Live-attenuated vaccines like MMR are contraindicated in pregnancy due to potential harm to the developing fetus.

Evaluate the action regarding preoperative sedatives and informed consent.

Giving the sedative before consent is signed is incorrect.

Medications that alter mental status legally invalidate the client's capacity to give informed consent.

Evaluate the action regarding warfarin and the elevated INR.

Holding the medication and notifying the RN is correct.

An INR of 5.8 indicates critical over-anticoagulation, placing the client at severe risk for bleeding.

Evaluate the action regarding furosemide administration with borderline vitals.

Giving the diuretic is incorrect.

Tachycardia and borderline low blood pressure in a postoperative client suggest potential shock; diuretics will dangerously worsen hypovolemia.

Evaluate the action regarding pediatric dosage calculation.

Validating the math with a second nurse is correct.

Independent double-checks are a standard safety requirement for high-alert and pediatric weight-based medications.
