A practical nurse is caring for a client with a T4 spinal cord injury who suddenly reports a severe, pounding headache and blurred vision. The nurse notes that the client's face is flushed and profusely sweating. In which order should the practical nurse prioritize the following actions? (Arrange from first action to last action)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a client experiencing autonomic dysreflexia is to first elevate the head of the bed, then measure the blood pressure, followed by assessing the urinary catheter for blockages, notifying the registered nurse, and finally documenting the event.
Autonomic dysreflexia is a life-threatening neurological emergency characterized by severe hypertension, triggered by a noxious stimulus below the level of the spinal cord injury (typically T6 or higher). The absolute priority is to immediately lower the blood pressure by utilizing orthostatic hypotension, which is achieved by sitting the client upright. Once the immediate risk is slightly mitigated through positioning, the nurse must assess the blood pressure to establish a baseline. Following assessment, the nurse must systematically hunt for and remove the triggering stimulus (most commonly a full bladder or kinked urinary catheter). After these independent actions are taken, the RN or provider must be notified for further collaborative orders, and finally, all findings and actions are documented in the client's medical record.

Step-by-Step Solution

1
Elevate the head of the bed to a sitting position (90 degrees).
Induces orthostatic hypotension.
This is the most rapid way to lower the client's blood pressure, reducing the immediate risk of a cerebrovascular accident.
2
Measure the client's blood pressure.
Quantifies the severity of hypertension.
Establishes a vital sign baseline to monitor the effectiveness of interventions and communicate clearly with the healthcare team.
3
Check the urinary catheter for kinks or obstruction.
Identifies the potential noxious stimulus.
Bladder distention is the most common cause of autonomic dysreflexia; removing the stimulus often resolves the crisis.
4
Notify the registered nurse (RN) or provider.
Escalates care for the medical emergency.
Facilitates advanced collaborative interventions, such as administering prescribed rapid-acting antihypertensives, if the crisis continues.
5
Document all findings and interventions.
Provides an accurate medical record.
Ensures continuity of care and legal accountability after the client's immediate safety is secured.

Following the administration of intravenous furosemide to a client with heart failure, the practical nurse reviews the newly reported laboratory values. Which result indicates an urgent need to notify the registered nurse?

Show answer & explanation

Answer: A potassium level of 2.8 mEq/L2.8\text{ mEq/L}

Answer

A potassium level of 2.8 mEq/L2.8\text{ mEq/L}
Furosemide is a potassium-wasting loop diuretic. A potassium level of 2.8 mEq/L2.8\text{ mEq/L} is significantly below the normal range (3.53.5 to 5.0 mEq/L5.0\text{ mEq/L}) and represents severe hypokalemia. This condition can trigger life-threatening cardiac dysrhythmias, making it a critical value that requires immediate notification and intervention.

Step-by-Step Solution

1
Identify the medication classification and its primary adverse effects.
Furosemide is a loop diuretic known to cause the depletion of electrolytes, particularly potassium.
Understanding the medication helps anticipate potential physiological complications.
2
Evaluate each laboratory value against adult normal reference ranges.
The sodium, BUN, and glucose levels are normal. The potassium level is significantly low (normal is 3.53.5 to 5.0 mEq/L5.0\text{ mEq/L}).
Nurses must differentiate between expected baseline values and critical abnormalities.
3
Prioritize the abnormal finding for immediate reporting.
The hypokalemia is prioritized because it poses an immediate, life-threatening risk.
Low potassium can lead to fatal cardiac dysrhythmias, necessitating prompt medical intervention.

While providing care for a client with chronic angina, a practical nurse prepares to apply a new transdermal nitroglycerin patch. Place the following nursing actions in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: perform hand hygiene and put on gloves, remove the old patch, clean the old site, select a new site, and finally apply and label the new patch.
Administering a transdermal patch requires strict adherence to safety protocols for both the client and the nurse. The nurse must first protect themselves by donning gloves. Next, the old patch must be removed and the area cleansed to prevent an accidental overdose from residual medication. Finally, site rotation is practiced by selecting a new, hairless area before applying and labeling the new patch.

Step-by-Step Solution

1
Perform hand hygiene and put on clean gloves.
The nurse's hands are protected from inadvertent medication absorption.
Transdermal medications are easily absorbed through the skin. The nurse must protect themselves before handling the medication or the client's old patch.
2
Remove the old patch and fold it in half with the adhesive sides together.
The old medication source is safely removed and contained.
Leaving an old patch on while applying a new one can cause a dangerous overdose, leading to severe adverse effects such as profound hypotension.
3
Clean and dry the skin area where the old patch was located.
The previous application site is free of residual medication.
Residual medication left on the skin can continue to be absorbed if not washed away.
4
Select a new, intact, and hairless site on the client's upper body.
A safe and effective location is identified for the new dose.
Site rotation prevents skin breakdown and irritation while ensuring predictable medication absorption.
5
Apply the new patch and document the date, time, and initials on it.
The medication is administered and the action is clearly communicated.
Labeling the patch informs other nurses when the patch was placed and when it is due for removal or replacement.

Question 984Question →

A school-aged child weighing 4444 lb is receiving care in an outpatient clinic for a severe skin infection. The healthcare provider prescribes clindamycin 2424 mg/kg/day orally, to be divided into equal doses administered every 88 hours. The clinic pharmacy dispenses clindamycin oral suspension at a concentration of 7575 mg/55 mL. How many mL should the practical nurse administer for a single dose? (Record answer to the nearest tenth. Do not include units in answer.)

Show answer & explanation

Answer: 10.7

Answer

10.7
To determine the correct administration volume, the practical nurse must first ensure the client's weight is in kilograms (4444 lb ÷2.2=20\div 2.2 = 20 kg). Next, the total daily dose is calculated by multiplying the weight by the prescribed rate (2020 kg ×24\times 24 mg/kg/day = 480480 mg/day). Because the prescription states the medication is to be administered every 88 hours, there are 33 administration times per day. The single dose amount is 480480 mg ÷3=160\div 3 = 160 mg/dose. Finally, using the desired over have formula multiplied by the vehicle (160160 mg ÷75\div 75 mg ×5\times 5 mL), the total volume per dose is calculated as 10.666...10.666... mL. Following standard rounding rules to the nearest tenth, the final answer is 10.710.7 mL.

Step-by-Step Solution

1
Convert the client's weight from pounds to kilograms.
2020 kg
Weight-based medication dosing requires the client's weight to be in kilograms. (4444 lb ÷2.2\div 2.2 lb/kg = 2020 kg)
2
Calculate the total daily dose of the prescribed medication.
480480 mg/day
The prescribed dosage rate is 2424 mg/kg/day. Multiply the client's weight by this rate: 2020 kg ×24\times 24 mg/kg = 480480 mg for the entire day.
3
Determine the amount of medication required for a single dose.
160160 mg/dose
The medication is ordered to be administered every 88 hours, which equates to 33 doses in a 2424-hour period (24÷8=324 \div 8 = 3). Divide the total daily dose by 33: 480480 mg ÷3\div 3 doses = 160160 mg per dose.
4
Calculate the liquid volume to administer using the available pharmacy concentration.
10.666...10.666... mL
Use the formula (Desired ÷\div Have) ×\times Vehicle. The desired dose is 160160 mg, the available strength is 7575 mg, and the vehicle volume is 55 mL. (160160 mg ÷75\div 75 mg) ×5\times 5 mL = 10.666...10.666... mL.
5
Round the calculated volume to the nearest tenth as instructed.
10.710.7 mL
The digit in the hundredths place is 66, which means you round the tenths digit up from 66 to 77, resulting in a final answer of 10.710.7.

During morning rounds, a practical nurse evaluates a client who underwent a partial nephrectomy 18 hours ago. The morning laboratory report indicates a hemoglobin level of 7.8 g/dL (78 g/L). Upon assessment, the client's heart rate is 106 bpm and blood pressure is 104/62 mm Hg. The admission baseline blood pressure was 138/82 mm Hg. Which action should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the assessment data and laboratory values.

Answer

The correct action is to immediately notify the registered nurse regarding the assessment data and laboratory values.
The client is exhibiting classic signs of postoperative hemorrhage and early hypovolemic shock, evidenced by a significant drop in blood pressure from baseline, compensatory tachycardia, and a critically low hemoglobin level following a highly vascular surgery (partial nephrectomy). Within their scope of practice, the practical nurse must immediately escalate these critical findings to the registered nurse, who will coordinate emergency interventions with the healthcare provider.

Step-by-Step Solution

1
Analyze the provided laboratory values.
The hemoglobin level of 7.8 g/dL (78 g/L) is significantly low and indicates potential blood loss.
Identifying critical laboratory results is essential for recognizing postoperative complications.
2
Evaluate the client's current vital signs against their established baseline.
The heart rate is elevated (106 bpm) and the blood pressure has dropped significantly from the baseline of 138/82 mm Hg down to 104/62 mm Hg.
Changes in vital signs, especially a narrowing pulse pressure or dropping systolic pressure with tachycardia, can indicate physiological deterioration.
3
Synthesize the clinical findings.
The combination of a critically low hemoglobin level, tachycardia, and a significant drop in blood pressure strongly suggests active postoperative hemorrhage and early hypovolemic shock.
Connecting disparate clinical cues is required for sound clinical judgment and risk reduction.
4
Determine the priority nursing action within the practical nurse scope of practice.
The practical nurse must immediately escalate these critical findings to the registered nurse.
The registered nurse must perform a comprehensive assessment and collaborate with the healthcare provider to initiate emergency interventions, such as fluid resuscitation or blood transfusions.

Question 986Question →

Two hours following a large-volume paracentesis for the management of ascites, a client suddenly becomes increasingly restless. The assigned practical nurse obtains vital signs revealing a blood pressure of 92/54 mm Hg and an apical pulse of 118 beats per minute. Which of the following actions should the nurse prioritize? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the changes in the client's condition; Assist the registered nurse in preparing equipment for the administration of intravenous albumin; Apply a pulse oximeter to obtain a current oxygen saturation reading

Answer

The correct actions are to notify the registered nurse immediately, assist in preparing for intravenous albumin administration, and apply a pulse oximeter to assess oxygenation.
The correct answers represent immediate, life-saving interventions within the practical nursing scope of practice for a client experiencing early hypovolemic shock. The client's presentation of restlessness, tachycardia, and hypotension following a large-volume paracentesis indicates post-paracentesis circulatory dysfunction. In this emergency scenario, the priority is to address airway, breathing, and circulation (ABCs). The nurse must immediately escalate the findings to the registered nurse, obtain additional circulatory and respiratory data by applying a pulse oximeter, and prepare to assist with volume replacement therapies, such as intravenous albumin, which restores intravascular volume and blood pressure.

Step-by-Step Solution

1
Analyze the client's current clinical presentation and vital signs.
The client has new-onset restlessness, hypotension (92/54 mm Hg), and tachycardia (118 bpm) shortly after a major fluid removal procedure.
Recognizing abnormal data is the foundational step in clinical judgment and prioritization.
2
Identify the underlying pathophysiological process occurring.
These findings indicate post-paracentesis circulatory dysfunction, a form of hypovolemic shock caused by rapid fluid shifts out of the intravascular space.
Connecting symptoms to the physiological adaptation failure determines the urgency of the situation.
3
Determine the priority nursing actions within the practical nursing scope of practice.
The nurse must immediately escalate the critical findings to the RN, gather additional ABC data (oxygen saturation), and prepare for volume expansion therapy.
Prompt intervention is required to prevent severe tissue hypoperfusion and cardiovascular collapse.

A practical nurse is providing basic care for an immobile client who is receiving continuous enteral tube feedings and requires frequent perineal care due to a *Clostridioides difficile* infection. Which of the following actions should the nurse take? (Select all that apply)

Select all that apply

Show answer & explanation

Answer: Pause the enteral feeding infusion before lowering the head of the bed to turn the client.; Perform hand hygiene using soap and water rather than an alcohol-based hand rub after removing gloves.; Apply a moisture barrier ointment to the perineal skin after cleansing and patting the area dry.

Answer

The correct actions are pausing the feeding pump before lowering the bed, performing hand hygiene with soap and water, and applying a moisture barrier ointment.
Safe basic care requires prioritizing airway protection, infection control, and skin integrity. Pausing the enteral feeding before lowering the head of the bed prevents regurgitation and fatal aspiration. Performing hand hygiene with soap and water is mandatory for *Clostridioides difficile*, as alcohol-based rubs cannot destroy the spores. Applying a moisture barrier ointment protects the vulnerable perineal skin from the corrosive effects of frequent diarrheal stools.

Step-by-Step Solution

1
Identify the client's risk factors related to continuous enteral feeding and immobility.
The client is at high risk for aspiration if the head is lowered while the feeding is running, and at risk for skin breakdown from frequent diarrhea.
Recognizing aspiration and skin breakdown risks determines the necessary safety and comfort interventions during basic care.
2
Determine the appropriate infection control measures for a client with C. diff.
C. diff spores are resistant to alcohol, so handwashing with soap and water is mandatory. PPE must be removed in the correct sequence (gloves first) to prevent self-contamination.
Adhering to standard and transmission-based precautions ensures safe care delivery and prevents pathogen spread during hygiene tasks.
3
Apply the ABC (Airway, Breathing, Circulation) framework to potential changes in condition.
Sudden stridor indicates a compromised airway, which is an immediate emergency.
The ABC framework mandates that airway issues must always take precedence over basic hygiene and comfort tasks.

Question 988Question →

A practical nurse is caring for a client who has just returned to the unit after undergoing a percutaneous liver biopsy. Which of the following positions is most appropriate for the nurse to place the client in?

Show answer & explanation

Answer: Right side-lying

Answer

Right side-lying
Following a percutaneous liver biopsy, the client must be placed in a right side-lying position for several hours. Because the liver is a highly vascular organ located on the right side of the body, positioning the client on this side uses their own body weight to apply direct pressure to the puncture site, which effectively promotes hemostasis and prevents severe internal hemorrhage.

Step-by-Step Solution

1
Identify the procedure performed and its anatomical location.
The client had a percutaneous liver biopsy. The liver is a highly vascular organ located in the right upper quadrant of the abdomen.
Understanding the anatomical site of the procedure helps determine where pressure must be applied to prevent complications.
2
Determine the most significant immediate post-procedure risk.
The greatest immediate risk following a liver biopsy is internal bleeding (hemorrhage).
Prioritizing the primary post-operative complication guides the selection of the correct nursing intervention.
3
Select the position that minimizes this specific risk.
Placing the client in a right side-lying position applies the client's own body weight to create direct physical pressure on the biopsy site.
Direct pressure promotes hemostasis and reduces the risk of bleeding from the vascular tissue.

Question 989Question →

A practical nurse (PN) is monitoring a client who is three hours postoperative following a subtotal thyroidectomy. The client expresses feeling a tight sensation in the throat and is noted to be swallowing repeatedly. The client's heart rate has increased to 112 beats per minute, and blood pressure is 98/60 mm Hg. What is the priority action for the PN?

Show answer & explanation

Answer: Examine the surgical dressing and the posterior area of the neck for blood pooling.

Answer

Examine the surgical dressing and the posterior area of the neck for blood pooling.
The correct answer addresses the highest priority threat: Airway and Circulation. Frequent swallowing, a tight sensation in the neck, tachycardia, and borderline hypotension in a post-thyroidectomy client are cardinal signs of hemorrhage and hematoma formation. The practical nurse must immediately perform a focused assessment by checking the anterior dressing and the back of the neck, as gravity causes blood to pool posteriorly. This data is essential to confirm the emergency before quickly escalating the findings to the registered nurse and provider.

Step-by-Step Solution

1
Analyze the client's reported symptoms and behaviors.
Frequent swallowing and a tight sensation in the throat are identified as classic signs of bleeding or hematoma formation after neck surgery.
Blood can pool internally, causing a feeling of fullness and triggering the swallow reflex before external bleeding is readily visible.
2
Evaluate the client's vital signs.
The heart rate of 112 beats per minute and blood pressure of 98/60 mm Hg are recognized as borderline physiological parameters.
Tachycardia and a slightly lowered blood pressure are early compensatory mechanisms for hypovolemia due to acute hemorrhage.
3
Determine the priority nursing intervention based on the ABCs (Airway, Breathing, Circulation).
The practical nurse must immediately collect focused data to confirm the presence of hemorrhage before escalating the situation.
Because hemorrhage in the neck can rapidly compress the trachea and cause a loss of the airway, verifying the bleeding by checking the dressing and behind the neck is the absolute first step.

Show answer & explanation

Answer: Immediately report these findings to the supervising registered nurse.

Answer

The correct action is to immediately report these findings to the supervising registered nurse, as they indicate a potential hemorrhage.
The liver is a highly vascular organ, placing the client at high risk for internal hemorrhage following a biopsy. A sudden drop in blood pressure accompanied by an increased heart rate are classic signs of hypovolemic shock. The practical nurse must immediately report these critical findings to the registered nurse so that rapid medical interventions can be initiated.

Step-by-Step Solution

1
Evaluate the client's current vital signs.
The blood pressure is significantly low (hypotension) and the heart rate is elevated (tachycardia).
Identifying abnormal vital signs is the first step in recognizing a potential complication.
2
Relate the findings to the recent procedure.
The client recently had a liver biopsy, which involves a highly vascular organ.
A liver biopsy carries a significant risk of internal hemorrhage, which presents clinically as hypovolemic shock.
3
Determine the appropriate practical nurse scope of practice.
Escalate the critical findings to the registered nurse (RN).
The practical nurse must promptly report signs of hemodynamic instability to the RN for advanced assessment and collaborative intervention.

Question 991Question →

While assessing a client recovering from a chronic obstructive pulmonary disease (COPD) exacerbation, the practical nurse notes a sudden change in the client's baseline behavior. The 78-year-old client, who has been treated with high-dose intravenous corticosteroids for the past three days, is now highly agitated, disoriented, and reports a burning sensation in the epigastric region. The vital signs show a heart rate of 115 bpm, a blood pressure of 102/56 mm Hg, and an oxygen saturation of 89% on room air. What is the priority intervention for the practical nurse in this scenario?

Show answer & explanation

Answer: Initiate supplemental oxygen therapy and immediately notify the registered nurse of the changing condition.

Answer

Initiate supplemental oxygen therapy and immediately notify the registered nurse of the changing condition.
The client is exhibiting signs of a severe gastrointestinal bleed, a known complication of high-dose corticosteroid therapy (indicated by the epigastric pain). The combination of agitation, tachycardia (115 bpm), borderline hypotension (102/56 mm Hg), and hypoxia (SpO2 89%) indicates impending hypovolemic shock and poor tissue perfusion. The practical nurse must prioritize ABCs (Airway, Breathing, Circulation) by applying oxygen to treat the hypoxia and immediately escalating the situation to the registered nurse for rapid medical intervention.

Step-by-Step Solution

1
Analyze the clinical cues, including the history of corticosteroid use, epigastric pain, and new-onset agitation.
Identify that these findings suggest a potential gastrointestinal bleed.
Corticosteroids significantly increase the risk of peptic ulcers. Sudden bleeding can lead to decreased cerebral perfusion, causing the acute agitation.
2
Evaluate the current vital signs (Heart rate 115 bpm, Blood pressure 102/56 mm Hg, SpO2 89%).
Recognize that the client is experiencing hypoxia and early signs of hypovolemic shock.
Tachycardia and a narrowing or dropping blood pressure are compensatory mechanisms for volume loss, while hypoxia results from decreased oxygen-carrying capacity.
3
Determine the priority nursing action based on the ABC framework (Airway, Breathing, Circulation) and the practical nurse scope of practice.
Select the intervention that addresses oxygenation and rapidly involves the registered nurse.
Applying oxygen directly treats the breathing deficit, and a rapidly decompensating client requires immediate RN-level assessment and collaborative intervention.

Question 992Question →

A practical nurse is monitoring a client who recently returned from the post-anesthesia care unit following abdominal surgery. Which of the following assessment findings should the nurse identify as early indicators of hypovolemic shock? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Heart rate of 118118 beats per minute; Blood pressure decreasing from 128/82 mm Hg128/82\text{ mm Hg} to 98/60 mm Hg98/60\text{ mm Hg}; Client reports of sudden, severe thirst

Answer

The findings that indicate early hypovolemic shock are a heart rate of 118 beats per minute, a blood pressure decreasing from 128/82 mm Hg to 98/60 mm Hg, and client reports of sudden, severe thirst.
Early signs of hypovolemic shock include compensatory mechanisms such as an elevated heart rate (tachycardia) and severe thirst as the body attempts to maintain circulating volume and cardiac output. A subsequent drop in blood pressure confirms that the cardiovascular system is struggling to adapt to the fluid loss. Recognizing this cluster of findings is crucial for early intervention.

Step-by-Step Solution

1
Analyze the clinical scenario and the client's current risk factors.
The client is in the early postoperative phase, making them highly vulnerable to hemorrhage and subsequent fluid volume deficit.
Understanding the primary postoperative risks directs the nurse to monitor specific physiological adaptations.
2
Evaluate the assessment findings against the clinical signs of circulatory compromise.
Tachycardia, dropping blood pressure, and intense thirst are identified as classic signs of reduced circulating blood volume.
The body compensates for fluid loss by increasing the heart rate and triggering the thirst mechanism before ultimately failing to maintain blood pressure.
3
Differentiate acute signs of deterioration from expected postoperative findings.
Incisional pain and a low-grade temperature are excluded as indicators of shock because they are expected responses to surgical trauma.
This ensures the nurse prioritizes potentially life-threatening circulatory changes over routine, stable postoperative symptoms.

Key Concept

Early recognition of hypovolemic shock involves identifying compensatory cardiovascular changes such as tachycardia, hypotension, and systemic responses like thirst.
Question 993Question →

An older adult client is recovering on a surgical unit two days after undergoing an abdominal procedure. The client, who was previously oriented and cooperative, now exhibits sudden restlessness and confusion about their current location. The latest vital signs reveal a heart rate of 114 beats/min and a blood pressure of 98/58 mm Hg. Which of the following is the priority action for the practical nurse?

Show answer & explanation

Answer: Measure the client's oxygen saturation and promptly report the status change to the registered nurse.

Answer

The correct action is to measure the client's oxygen saturation and promptly report the status change to the registered nurse.
The correct response prioritizes the 'Airway, Breathing, Circulation' (ABC) framework in a client exhibiting sudden acute changes. Restlessness and confusion, combined with borderline vital signs (tachycardia and mild hypotension), are early indicators of hypoxia, shock, or sepsis in a post-operative client. The practical nurse must immediately gather relevant oxygenation data and escalate these critical findings to the registered nurse for prompt intervention.

Step-by-Step Solution

1
Analyze the clinical cues presented by the client.
The client has a sudden onset of restlessness and confusion, alongside a heart rate of 114 beats/min and blood pressure of 98/58 mm Hg.
Identifying sudden changes in mental status and borderline hemodynamics is crucial for recognizing early deterioration.
2
Prioritize the cues using the ABC (Airway, Breathing, Circulation) framework.
Sudden restlessness is a classic early sign of hypoxia (Breathing), and the tachycardia with mild hypotension suggests compensatory mechanisms for shock or poor perfusion (Circulation).
Life-threatening physiological issues must be addressed before secondary concerns like pain or routine charting.
3
Determine the most appropriate action within the practical nursing scope of practice.
The practical nurse must collect focused data, such as oxygen saturation, and immediately escalate the findings to the registered nurse for rapid medical intervention.
Acute decompensation requires collaborative management and timely intervention beyond routine practical nurse monitoring.

Question 994Question →

A practical nurse is providing basic care for a client who is 3 days postoperative following a surgical evacuation of a subdural hematoma. The client has residual right-sided hemiplegia and severe dysphagia, requiring maximum assistance with activities of daily living. Which care interventions should the nurse implement? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Place the client's right arm on a pillow in slight abduction and external rotation while they are supine.; Guide the client to tuck their chin downward toward the chest when swallowing pureed foods.; Begin putting garments on the right side of the client's body first when assisting with dressing.

Answer

The appropriate interventions include placing the affected arm in slight abduction and external rotation, guiding the client to tuck their chin when swallowing, and dressing the affected right side first.
Supporting the flaccid limb in slight abduction and external rotation prevents adduction contractures and painful shoulder subluxation. Tucking the chin during swallowing protects the airway by widening the valleculae and directing food away from the trachea, preventing aspiration. When assisting a client with hemiplegia to dress, putting garments on the affected side first prevents unnecessary stretching, pulling, and potential dislocation of the paralyzed joints.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has right-sided hemiplegia (paralysis) and severe dysphagia (difficulty swallowing) following a neurosurgical procedure.
Understanding the specific deficits dictates the requirements for safe mobility, hygiene, and nutritional support.
2
Evaluate the positioning and mobility interventions for hemiplegia.
The affected right arm needs support in abduction/external rotation. The wheelchair must be placed on the strong left side for transfers. Firm objects should not be placed in the spastic hand.
Proper joint alignment prevents subluxation and contractures. Transferring toward the strong side ensures the client can bear weight safely. Stimulating the palm triggers the grasp reflex, worsening contractures.
3
Evaluate the nutritional and feeding interventions for dysphagia.
The chin-tuck maneuver should be utilized. Straws must be avoided.
Tucking the chin protects the airway from aspiration. Straws bypass the oral preparatory phase and deliver fluids too quickly to the pharynx, risking aspiration.
4
Evaluate the hygiene and dressing sequence.
The affected right side must be dressed first.
Dressing the weak side first minimizes the need to bend or awkwardly pull on flaccid limbs, protecting the joints from injury.

Key Concept

Basic care for clients with hemiplegia and dysphagia requires synthesizing principles of joint alignment, airway protection during feeding, and maximizing safety during ADLs.

A practical nurse is providing care for a client who returned to the nursing unit one hour ago following a percutaneous liver biopsy. Which interventions should the nurse implement to promote comfort and ensure client safety? (Select all that apply)

Select all that apply

Show answer & explanation

Answer: Position the client on the right side with a small rolled towel beneath the puncture site.; Provide a bedpan for elimination needs to maintain strict bed rest requirements.; Dim the room lights and minimize external noise to facilitate a restful environment.

Answer

The nurse should position the client on the right side with a towel under the puncture site, provide a bedpan to maintain bed rest, and dim the lights to create a restful environment.
Following a liver biopsy, preventing hemorrhage is the primary physiological goal. Positioning the client on the right side applies direct, continuous pressure to the puncture site. Maintaining strict bed rest with the use of a bedpan ensures physical exertion is minimized, further reducing bleeding risks. Finally, controlling the environment by dimming lights addresses the client's basic comfort needs without compromising safety.

Step-by-Step Solution

1
Analyze the procedure and potential complications.
A percutaneous liver biopsy carries a high risk of internal hemorrhage due to the high vascularity of the liver.
Understanding the primary risk determines the necessary safety interventions.
2
Determine the appropriate postoperative positioning.
The client must be placed on their right side with a pillow or towel under the puncture site.
This specific position applies external physical pressure directly to the liver capsule to aid in hemostasis.
3
Identify the required activity level for the client.
The client must remain on strict bed rest and use a bedpan for elimination.
Physical exertion or ambulation increases abdominal pressure and heart rate, which can dislodge clots and cause bleeding.
4
Select basic comfort measures that do not interfere with safety.
Dimming lights and reducing noise promotes necessary rest.
Environmental control provides comfort while supporting the physiological need for bed rest.

Key Concept

Post-procedure basic care, comfort, and positioning to prevent hemorrhage.

A practical nurse is caring for an adult client who was recently diagnosed with a respiratory tract infection. The healthcare provider prescribes oral azithromycin 0.5 g0.5\text{ g} to be administered once daily. The pharmacy dispenses a reconstituted oral suspension labeled 250 mg/5 mL250\text{ mg}/5\text{ mL}. How many milliliters (mL\text{mL}) should the nurse administer to the client for each dose?

Show answer & explanation

Answer: 10 mL10\text{ mL}

Answer

The nurse should administer 10 mL10\text{ mL} of the oral suspension per dose.
The correct dose is 10 mL10\text{ mL}. To determine this, the practical nurse must first convert the prescribed 0.5 g0.5\text{ g} to 500 mg500\text{ mg}. Using the standard formula of (Desired / Have) \times Volume, the equation becomes (500 mg/250 mg500\text{ mg} / 250\text{ mg}) \times 5\text{ mL}.Thissimplifiesto. This simplifies to 2 \times 5\text{ mL},whichequals, which equals 10\text{ mL}$.

Step-by-Step Solution

1
Convert the prescribed dose from grams to milligrams to ensure units match the supplied medication.
0.5 g=500 mg0.5\text{ g} = 500\text{ mg}
Units of measurement must be identical before a dosage calculation can be accurately performed.
2
Set up the dosage calculation using the standard formula: (Desired dose / Available dose) x Volume.
(500 mg/250 mg500\text{ mg} / 250\text{ mg}) \times 5\text{ mL}$
This formula accounts for both the concentration of the medication and the volume of liquid it is suspended in.
3
Perform the division and multiplication to find the final volume to administer.
2×5 mL=10 mL2 \times 5\text{ mL} = 10\text{ mL}
Solving the equation provides the precise volume required to safely deliver the prescribed amount of medication.

Question 998Question →

A practical nurse (PN) is preparing to administer a prescribed dose of cefdinir oral suspension to a pediatric client with acute otitis media. The client's weight is 27 pounds 8 ounces. The provider's prescription reads: cefdinir 14 mg/kg/day by mouth, divided in equal doses every 12 hours. The pharmacy supplies a bottle of cefdinir powder for oral suspension. The reconstitution instructions on the label state: "Add 38 mL of sterile water to the bottle to yield a final concentration of 125 mg/5 mL." How many milliliters (mL) should the PN administer for a single dose? (Record answer to the nearest tenth. Do not include units in answer.)

Show answer & explanation

Answer: 3.5

Answer

3.5
To determine the correct volume to administer, the nurse must execute four specific calculations. First, convert the weight of 27 pounds 8 ounces to kilograms (27.5 lbs÷2.2=12.5 kg27.5\text{ lbs} \div 2.2 = 12.5\text{ kg}). Second, calculate the total daily dose (12.5 kg×14 mg/kg/day=175 mg/day12.5\text{ kg} \times 14\text{ mg/kg/day} = 175\text{ mg/day}). Third, divide the daily dose by the frequency (every 12 hours = 2 doses per day; 175 mg÷2=87.5 mg/dose175\text{ mg} \div 2 = 87.5\text{ mg/dose}). Finally, use dimensional analysis with the reconstituted concentration (125 mg125\text{ mg} in 5 mL5\text{ mL}) to find the volume: (87.5 mg125 mg\frac{87.5\text{ mg}}{125\text{ mg}}) ×5 mL=3.5 mL\times 5\text{ mL} = 3.5\text{ mL}. The 38 mL38\text{ mL} of diluent is distractor information required only during the actual mixing process.

Step-by-Step Solution

1
Convert the client's weight from pounds and ounces to kilograms.
12.5
Weight-based dosing requires the client's weight in kilograms. 88 ounces is 0.50.5 pounds (8÷168 \div 16), making the total weight 27.527.5 pounds. Dividing 27.527.5 by 2.22.2 yields 12.5 kg12.5\text{ kg}.
2
Calculate the total daily dose in milligrams.
175
Multiply the prescribed dose of 14 mg/kg/day14\text{ mg/kg/day} by the client's weight of 12.5 kg12.5\text{ kg} to get 175 mg/day175\text{ mg/day}.
3
Calculate the single dose amount.
87.5
The total daily dose is divided every 12 hours, which means 2 doses per day. 175 mg175\text{ mg} divided by 2 equals 87.5 mg87.5\text{ mg} per dose.
4
Calculate the volume of the single dose using the final concentration.
3.5
Using the final reconstituted concentration of 125 mg125\text{ mg} per 5 mL5\text{ mL}: 87.5 mg125 mg×5 mL=3.5 mL\frac{87.5\text{ mg}}{125\text{ mg}} \times 5\text{ mL} = 3.5\text{ mL}.

A practical nurse (PN) is assigned to care for a 7474-year-old client who is prescribed daily oral lithium carbonate for the management of bipolar disorder. The client's morning laboratory panel reveals a serum lithium level of 1.91.9 mEq/L and a serum sodium level of 130130 mEq/L. During data collection, the PN notes that the client is exhibiting a coarse hand tremor, ataxia, and new-onset acute confusion. Which of the following is the priority action for the PN?

Show answer & explanation

Answer: Withhold the scheduled medication dose and immediately notify the registered nurse (RN) of the clinical findings.

Answer

The correct action is to withhold the scheduled medication dose and immediately notify the registered nurse (RN) of the clinical findings.
The client is exhibiting clear physiological and laboratory signs of lithium toxicity, which constitutes a medical emergency. The therapeutic range for maintenance lithium is 0.60.6 to 1.21.2 mEq/L; a level of 1.91.9 mEq/L is highly toxic. Furthermore, the client's hyponatremia (sodium level of 130130 mEq/L) causes the kidneys to resorb lithium instead of excreting it, worsening the toxicity. The safest and most appropriate action within the PN scope of practice is to withhold the scheduled dose and immediately report these critical, life-threatening findings to the supervising RN or provider.

Step-by-Step Solution

1
Analyze the client's laboratory results in the context of the prescribed medication.
The serum lithium level of 1.91.9 mEq/L is critically high (therapeutic range is 0.60.6 to 1.21.2 mEq/L). The serum sodium level of 130130 mEq/L indicates hyponatremia.
Hyponatremia causes the kidneys to retain lithium, significantly increasing the risk and severity of lithium toxicity.
2
Correlate the laboratory data with the client's physical assessment findings.
The client exhibits coarse hand tremors, ataxia, and acute confusion.
These are classic, dangerous neurological manifestations of advanced lithium toxicity that require immediate medical intervention.
3
Determine the safest appropriate intervention within the practical nurse (PN) scope of practice.
The PN must withhold the medication to prevent further harm and urgently report the findings to the RN or healthcare provider.
Administering the medication would worsen the toxicity, and managing a toxic overdose requires RN and provider-level interventions.

A practical nurse is preparing to collect a urine specimen for culture and sensitivity from a client who has an indwelling urinary catheter. Arrange the following steps for this procedure in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first clamp the drainage tubing, then scrub the collection port, aspirate the urine with a sterile syringe, transfer it to a sterile container, and finally unclamp the drainage tubing.
The proper procedure for collecting a sterile urine specimen from a closed urinary drainage system minimizes the risk of introducing pathogens and ensures accurate laboratory results. Clamping the tube allows fresh urine to collect. Scrubbing the port maintains sterility. Aspirating and transferring the specimen completes the sterile collection, and unclamping the tube ensures client safety by restoring normal urinary drainage.

Step-by-Step Solution

1
Clamp the drainage tubing.
Fresh urine accumulates near the collection port.
Urine collected from the drainage bag is not sterile; fresh urine must be collected directly from the catheter tubing.
2
Scrub the collection port with an antiseptic wipe.
The surface of the port is disinfected.
This prevents bacteria from being pushed into the catheter system or contaminating the sample during aspiration.
3
Aspirate urine using a sterile syringe.
The required volume of fresh urine is obtained.
A sterile syringe maintains the closed system while safely extracting the sample.
4
Transfer the urine to a sterile specimen container.
The specimen is safely secured for transport.
Maintaining the sterility of the container's interior ensures accurate laboratory culture results.
5
Unclamp the drainage tubing.
Continuous urine flow into the drainage bag is restored.
Prolonged clamping can cause severe bladder distention and increases the risk of urinary tract infection.
