Following a total thyroidectomy, an adult client is admitted to the surgical step-down unit. To minimize the potential for severe postoperative complications, which actions and assessments must the nurse include in the plan of care? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Maintain the client in a semi-Fowler's position with the head and neck supported by pillows.; Verify that a tracheostomy tray, oxygen, and suction equipment are present at the bedside.; Monitor the client for reports of circumoral numbness, tingling, or muscle twitching.

Answer

The correct interventions include maintaining a semi-Fowler's position with neck support, ensuring emergency airway equipment is at the bedside, and monitoring for signs of hypocalcemia such as circumoral numbness.
Following a thyroidectomy, clients are at extremely high risk for airway compromise, hemorrhage, and hypocalcemia. Maintaining a semi-Fowler's position reduces edema and minimizes tension on the anterior neck incision. Having a tracheostomy tray and suction equipment readily available is essential for immediate airway management if a rapid hematoma develops. Furthermore, monitoring for circumoral numbness or muscle twitching allows for early detection of hypocalcemia, a common complication resulting from inadvertent parathyroid gland injury.

Step-by-Step Solution

1
Identify the primary life-threatening complications associated with a total thyroidectomy.
The major risks are airway obstruction (from edema or hematoma), severe hemorrhage, and acute hypocalcemia (from parathyroid damage).
Understanding the specific risks guides the nurse in prioritizing appropriate reduction strategies.
2
Determine the optimal positioning to reduce surgical site complications.
The client should be placed in a semi-Fowler's position with the head and neck carefully supported by pillows or sandbags.
This position promotes venous return to reduce swelling and prevents hyper-extension of the neck, which could tear the suture line.
3
Select interventions that prepare for sudden airway emergencies.
A tracheostomy tray, suction equipment, and oxygen must be immediately accessible at the bedside.
If a hematoma rapidly expands and compresses the trachea, an emergency tracheostomy may be required to save the client's life.
4
Identify early clinical markers of parathyroid gland injury.
The nurse must assess for circumoral numbness, tingling in the extremities, and muscle twitching (Chvostek's or Trousseau's signs).
Inadvertent removal or trauma to the parathyroid glands during surgery causes a sudden drop in serum calcium, requiring immediate calcium gluconate administration.

A nurse is performing a reassessment on a young adult client admitted with an acute asthma exacerbation. The client initially presented with marked tachypnea, use of accessory muscles, and loud bilateral wheezing. Thirty minutes later, the nurse observes that the client's respirations have become shallow, wheezing is no longer audible, and the client appears drowsy. Arterial blood gas (ABG) results reveal a pH\text{pH} of 7.287.28, a PaCO2\text{PaCO}_2 of 58 mm Hg58\text{ mm Hg}, and an HCO3−\text{HCO}_3^- of 24 mEq/L24\text{ mEq/L}. Which of the following is the priority nursing action?

Show answer & explanation

Answer: Notify the rapid response team and gather supplies for endotracheal intubation

Answer

Notify the rapid response team and gather supplies for endotracheal intubation.
The combination of a 'silent chest' (absent wheezing with shallow respirations), drowsiness, and respiratory acidosis (pH\text{pH} 7.28, PaCO2\text{PaCO}_2 58) in an asthma patient signifies profound muscle fatigue and impending respiratory failure. Immediate intubation and mechanical ventilation are required to save the client's life.

Step-by-Step Solution

1
Analyze the physical assessment changes.
The client transitioned from tachypnea and loud wheezing to shallow respirations, no audible wheezing ('silent chest'), and drowsiness.
Sudden loss of wheezing with decreased level of consciousness indicates extreme muscle fatigue and complete airway obstruction, a medical emergency.
2
Interpret the arterial blood gas (ABG) results.
The pH is 7.28 (acidosis) and PaCO2 is 58 mm Hg (elevated), indicating uncompensated respiratory acidosis.
Early asthma exacerbations typically present with respiratory alkalosis due to hyperventilation. A shift to respiratory acidosis signifies that the client can no longer maintain adequate ventilation.
3
Determine the priority clinical intervention.
The nurse must immediately call for help and prepare for advanced airway management (intubation and mechanical ventilation).
The client is in impending respiratory failure. Airway and breathing take the highest priority, and pharmacological interventions will not be effective without adequate airflow.

Key Concept

An older adult client is transferred to the medical-surgical unit after a cardiac catheterization accessed via the right femoral artery. The client is on bed rest, has a history of osteoarthritis, and reports generalized back stiffness. Which of the following nursing actions should be included in the client's basic care and comfort plan? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Administer a gentle back massage to alleviate musculoskeletal stiffness while keeping the right leg straight.; Place a small, flat pillow under the client's head and neck to reduce cervical strain.

Answer

The nurse should administer a gentle back massage while keeping the right leg straight, and place a small, flat pillow under the client's head and neck.
Providing a back massage and using a small neck pillow safely address the client's osteoarthritis and generalized stiffness without compromising the required straight alignment of the affected leg. Maintaining a straight right leg and keeping the head of the bed at 30 degrees or lower is crucial to prevent arterial bleeding at the femoral access site.

Step-by-Step Solution

1
Analyze the client's specific post-procedure safety requirements.
Following a femoral cardiac catheterization, the affected extremity must remain completely straight (with the head of the bed flat or minimally elevated) to prevent bleeding and hematoma formation at the puncture site.
Flexing the hip joint increases pressure on the femoral artery access site.
2
Evaluate comfort measures for a client with osteoarthritis on strict bed rest.
A back massage and a small neck pillow provide musculoskeletal relief without violating the strict positioning requirements of the right leg.
Basic care and comfort must be balanced with post-procedural safety restrictions.
3
Assess the delegation and clinical judgment actions presented in the options.
Initial pulse evaluations cannot be delegated to UAPs, and acute cognitive changes must be investigated as complications rather than normal aging.
Adhering to scope of practice and recognizing acute pathological changes are critical components of safe nursing care.

An adult weighing 176 lb176\text{ lb} requires vasopressor support for septic shock. The critical care provider prescribes a norepinephrine infusion to begin at 0.05 mcg/kg/min0.05\text{ mcg/kg/min}. The available IV bag contains 4 mg4\text{ mg} of norepinephrine mixed in 250 mL250\text{ mL} of 5%5\% dextrose in water (D5W). At how many mL/hr\text{mL/hr} will the infusion pump run? Record your answer using a whole number.

Show answer & explanation

Answer: 15

Answer

15
To determine the correct IV pump rate for a weight-based continuous infusion, dimensional analysis or step-by-step conversion must be utilized. First, the client's weight is converted to kilograms (176÷2.2=80 kg176 \div 2.2 = 80\text{ kg}). The ordered dose (0.05 mcg/kg/min0.05\text{ mcg/kg/min}) is multiplied by the weight to find the per-minute dose (4 mcg/min4\text{ mcg/min}). Because IV pumps run in hours, this is multiplied by 6060 to find the hourly dose (240 mcg/hr240\text{ mcg/hr}). Next, the concentration of the IV bag is determined by converting the supply to micrograms (4 mg=4000 mcg4\text{ mg} = 4000\text{ mcg}) and dividing by the volume (4000 mcg÷250 mL=16 mcg/mL4000\text{ mcg} \div 250\text{ mL} = 16\text{ mcg/mL}). Finally, the required hourly dose is divided by the concentration (240÷16=15 mL/hr240 \div 16 = 15\text{ mL/hr}).

Step-by-Step Solution

1
Convert weight from pounds to kilograms by dividing by 2.2.
176 lb÷2.2 lb/kg=80 kg176\text{ lb} \div 2.2\text{ lb/kg} = 80\text{ kg}
Weight-based dosing formulas require the client's mass in kilograms.
2
Calculate the per-minute medication dose.
0.05 mcg/kg/min×80 kg=4 mcg/min0.05\text{ mcg/kg/min} \times 80\text{ kg} = 4\text{ mcg/min}
This establishes the exact amount of drug the patient must receive every minute.
3
Convert the per-minute dose to an hourly dose.
4 mcg/min×60 min/hr=240 mcg/hr4\text{ mcg/min} \times 60\text{ min/hr} = 240\text{ mcg/hr}
Infusion pumps are programmed in mL/hr, so the dose must be scaled to an hourly rate.
4
Standardize units by converting the total milligrams of norepinephrine to micrograms.
4 mg×1000 mcg/mg=4000 mcg4\text{ mg} \times 1000\text{ mcg/mg} = 4000\text{ mcg}
The prescribed dose is in micrograms, so the available supply must be converted to the same unit to calculate concentration.
5
Calculate the drug concentration per milliliter of IV fluid.
4000 mcg÷250 mL=16 mcg/mL4000\text{ mcg} \div 250\text{ mL} = 16\text{ mcg/mL}
This determines how much drug is delivered in every 1 mL of fluid.
6
Calculate the final infusion pump rate.
240 mcg/hr÷16 mcg/mL=15 mL/hr240\text{ mcg/hr} \div 16\text{ mcg/mL} = 15\text{ mL/hr}
Dividing the hourly dose by the concentration yields the required fluid volume per hour.

Question 45Question →

An adult client hospitalized with rapid atrial fibrillation is receiving a continuous intravenous (IV) infusion of diltiazem to maintain ventricular rate control. The client has a single peripheral IV catheter located in the left forearm. The healthcare provider prescribes a scheduled dose of intravenous pantoprazole. The nurse consults the facility's pharmacology reference and notes that pantoprazole is physically incompatible with diltiazem. Which action should the nurse take to safely administer the prescribed medication?

Show answer & explanation

Answer: Insert an additional peripheral intravenous catheter in a different location to infuse the medication independently.

Answer

The nurse must insert an additional peripheral intravenous catheter in a different location to infuse the medication independently.
When a client is receiving a critical, continuous medication infusion (such as diltiazem for rate control) that cannot be safely paused, and a newly prescribed medication is physically incompatible with that continuous infusion, the nurse must establish a separate intravenous access site. This prevents chemical precipitation from drug incompatibility and ensures the client's hemodynamic stability is not compromised by interrupting the critical continuous drip.

Step-by-Step Solution

1
Identify the continuous medication being administered and evaluate its clinical purpose.
The client is receiving diltiazem, a critical continuous infusion necessary to control a rapid ventricular rate.
Understanding the necessity of an active infusion determines whether it can be safely paused to administer other treatments.
2
Review the compatibility of the newly prescribed medication with the primary continuous infusion.
The pharmacology reference confirms that pantoprazole is physically incompatible with diltiazem.
Incompatible medications mixed in the same intravenous line can form lethal precipitates, causing emboli, catheter blockages, or chemical inactivation.
3
Determine the safest method to administer both required medications without causing patient harm.
A new, independent peripheral intravenous line must be established for the pantoprazole.
The critical rate-control infusion cannot be paused without risking patient instability, and the incompatible drugs cannot share the same venous access.

Question 46Question →

A nurse is caring for a client with a history of adrenal insufficiency who was admitted for management of severe gastroenteritis. During the most recent assessment, the client appears increasingly lethargic. Vital signs show the heart rate has trended from 8282 to 114 beats/min114 \text{ beats/min}, and the blood pressure has shifted from 118/76 mm Hg118/76 \text{ mm Hg} to 102/84 mm Hg102/84 \text{ mm Hg}. Current laboratory results indicate a serum sodium of 131 mEq/L131 \text{ mEq/L} (131 mmol/L131 \text{ mmol/L}), serum potassium of 5.8 mEq/L5.8 \text{ mEq/L} (5.8 mmol/L5.8 \text{ mmol/L}), and an arterial blood gas (ABG) revealing a pH\text{pH} of 7.317.31, PaCO2\text{PaCO}_2 of 36 mm Hg36 \text{ mm Hg}, and HCO3−\text{HCO}_3^- of 18 mEq/L18 \text{ mEq/L} (18 mmol/L18 \text{ mmol/L}). Which of the following is the priority nursing intervention?

Show answer & explanation

Answer: Initiate a rapid intravenous infusion of 0.9% sodium chloride.

Answer

The correct priority intervention is to initiate a rapid intravenous infusion of 0.9% sodium chloride to treat impending hypovolemic shock.
This client is demonstrating early signs of hypovolemic shock (tachycardia and a notably narrowed pulse pressure) exacerbated by underlying adrenal insufficiency and gastroenteritis. In any shock state, the absolute priority according to the ABCs (Airway, Breathing, Circulation) framework is to restore intravascular volume. A rapid infusion of an isotonic crystalloid, such as 0.9%0.9\% sodium chloride, is the most immediate life-saving intervention to support blood pressure, enhance tissue perfusion, and prevent total cardiovascular collapse.

Step-by-Step Solution

1
Analyze the clinical presentation and vital sign trends.
The client has a history of adrenal insufficiency, ongoing fluid loss from gastroenteritis, new-onset lethargy, tachycardia (114 beats/min114 \text{ beats/min}), and a narrowing pulse pressure (102/84 mm Hg102/84 \text{ mm Hg}, which is a pulse pressure of 18 mm Hg18 \text{ mm Hg}).
These findings represent the early, compensatory phase of hypovolemic shock progressing toward an acute adrenal (Addisonian) crisis.
2
Interpret the laboratory and arterial blood gas data.
Labs reveal hyponatremia, hyperkalemia, and uncompensated metabolic acidosis.
The electrolyte imbalances are classic for aldosterone deficiency, while the metabolic acidosis is primarily a result of tissue hypoperfusion causing lactic acid buildup.
3
Determine the priority action using the Airway, Breathing, Circulation (ABC) framework.
The most immediate life-threatening issue is a profound circulation deficit requiring rapid volume replacement.
Isotonic crystalloids (like 0.9%0.9\% sodium chloride) are the universal first-line treatment to restore intravascular volume, support blood pressure, and reverse tissue hypoperfusion.

Key Concept

Early recognition and treatment of hypovolemic shock in acute adrenal insufficiency, prioritizing circulation and intravascular volume replacement.
Question 47Question →

An orthopedic unit nurse assumes care of a client who underwent a right above-the-knee amputation (AKA) twenty-four hours ago. The client's vital signs are currently stable, but they remain at high risk for physiological complications that could impede future rehabilitation. Which of the following nursing actions is most appropriate to reduce the client's risk of adverse physiological outcomes?

Show answer & explanation

Answer: Assist the client into a prone position for twenty to thirty minutes, three to four times a day.

Answer

The most appropriate action is to assist the client into a prone position for twenty to thirty minutes multiple times a day to prevent hip flexion contractures.
Following an above-the-knee amputation, the flexor muscles are naturally stronger than the extensors, pulling the hip into a flexed position. Placing the client in a prone position for short periods multiple times a day physically stretches these flexor muscles, effectively preventing the formation of a hip flexion contracture. This risk reduction strategy is crucial because a severe contracture makes fitting and successfully using a prosthetic leg nearly impossible.

Step-by-Step Solution

1
Identify the major long-term physiological risks associated with an above-the-knee amputation.
The primary mobility-related risk is a hip flexion contracture, which can make fitting and using a prosthetic limb impossible.
Understanding the specific post-surgical risks guides the nurse in selecting the correct preventive positioning interventions.
2
Evaluate the proposed positioning and assessment strategies against evidence-based risk reduction practices.
Prone positioning stretches the hip flexors. Conversely, elevating the limb on pillows or maintaining a high-Fowler's position promotes contractures. The described vital signs for shock are physiologically backwards.
Nursing interventions must be correctly applied to effectively reduce risk without inadvertently causing harm.

A healthcare provider prescribes an intravenous piggyback (IVPB) infusion of cefazolin 1 gram in 50 mL50\text{ mL} of 0.9% sodium chloride to be administered over 30 minutes30\text{ minutes}. The nurse should set the intravenous infusion pump to deliver how many mL/hr\text{mL/hr}? Record your answer using a whole number.

Show answer & explanation

Answer: 100

Answer

100
To determine the correct infusion pump setting in mL/hr, divide the total volume to be infused (50 mL) by the total time in minutes (30 minutes), and then multiply by 60 to convert minutes to hours. (50 mL / 30 min) * 60 min/hr = 100 mL/hr.

Step-by-Step Solution

1
Identify the total volume of the medication to be infused.
Total volume = 50 mL.
The medication is diluted in a specific amount of fluid that needs to be delivered.
2
Identify the prescribed duration of the infusion.
Time = 30 minutes.
The infusion pump rate must be calculated based on the total time over which the medication should be administered.
3
Set up the equation to calculate the infusion pump rate in mL/hr.
Rate (mL/hr) = (50 mL / 30 minutes) * 60 minutes/1 hour.
Infusion pumps are programmed in mL/hr, so minutes must be converted to hours.
4
Perform the calculation.
100
Multiplying (50/30) by 60 yields exactly 100 mL/hr, which is a whole number.

During the night shift, a nurse is monitoring a client admitted with acute decompensated heart failure and rapid atrial fibrillation. The client has a single 22-gauge peripheral intravenous catheter infusing continuous diltiazem. Assessment reveals a blood pressure of 92/60 mmHg, an irregular heart rate of 118 beats/min, and a respiratory rate of 28 breaths/min with audible crackles bilaterally. The provider orders a stat dose of intravenous furosemide. Upon checking the compatibility matrix, the nurse notes that furosemide is physically incompatible with diltiazem. What is the priority nursing action?

Show answer & explanation

Answer: Initiate a second peripheral intravenous catheter to administer the furosemide.

Answer

Initiate a second peripheral intravenous catheter to administer the furosemide.
The correct action is to initiate a second peripheral intravenous catheter. While standard nursing practice for incompatible medications often involves pausing the primary infusion and flushing the line before and after the secondary medication, this rule strictly does not apply to critical continuous infusions. Diltiazem is a short-acting rate-control medication; pausing it in a client with a rapid heart rate of 118 beats/min and borderline hypotension will lead to rapid loss of rate control and further hemodynamic compromise. Because the medications are physically incompatible and cannot be mixed in the same line, establishing independent intravenous access is the only way to safely deliver the urgent furosemide without interrupting the essential diltiazem drip.

Step-by-Step Solution

1
Analyze the client's current clinical stability and the purpose of the ongoing therapy.
The client is hemodynamically borderline (BP 92/60, HR 118) and relies on the continuous diltiazem infusion to prevent the ventricular rate from accelerating further.
Understanding the physiological necessity of the current continuous infusion is critical before altering its delivery.
2
Identify the pharmacological conflict presented in the scenario.
Diltiazem and furosemide are physically incompatible and cannot share the same intravenous line or Y-site without precipitating.
Mixing incompatible medications can cause crystallization, leading to loss of drug efficacy and fatal embolus formation.
3
Evaluate standard compatibility protocols against the client's specific acuity.
The standard protocol of pausing the primary fluid, flushing, administering the secondary drug, and restarting cannot be applied here because interrupting the diltiazem will cause dangerous rebound tachycardia.
Continuous antiarrhythmic and vasoactive medications have very short half-lives and must not be interrupted in unstable clients.
4
Determine the safest and most effective intervention.
The only safe action is to establish a new, independent intravenous access line to administer the furosemide.
This ensures the client receives the life-saving diuretic immediately without compromising the critical rate-control infusion.

An older adult client is bedbound and recovering from severe bacterial pneumonia when they develop sudden, acute agitation and confusion. The nursing team is establishing interventions to address the client's basic care, comfort, and safety needs. Which of the following actions should be included in the care plan? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Implement a scheduled turning and toileting routine every two hours to manage incontinence and protect skin integrity.; Provide a quiet environment with dim lighting and minimize unnecessary monitor alarms to reduce sensory overload.

Answer

The correct interventions are implementing a scheduled turning and toileting routine every two hours, and providing a quiet environment with dim lighting to reduce sensory overload.
Implementing a scheduled turning and toileting routine protects the client's skin integrity and proactively manages incontinence, which is a critical basic care standard for a bedbound client. Furthermore, providing a quiet, dimly lit environment with minimal alarms is an essential non-pharmacological comfort measure that actively reduces sensory stimulation and helps de-escalate acute agitation.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has bacterial pneumonia, is bedbound, and is experiencing sudden acute agitation (delirium).
Understanding the interplay of infection, immobility, and altered mental status guides the prioritization of airway protection, skin integrity, and non-pharmacological comfort.
2
Evaluate positioning and comfort needs based on the pathophysiology.
The client requires positioning that promotes lung expansion, routines that protect skin integrity, and an environment that prevents overstimulation.
Bacterial pneumonia necessitates head elevation; being bedbound demands strict turning schedules; agitation requires a calm, low-stimulus environment.
3
Differentiate between appropriate nursing actions and contraindicated practices.
Delegating skin assessments, attributing delirium to normal aging, using flat positioning during a respiratory illness, and prematurely utilizing physical restraints are identified as contraindicated.
Nurses must adhere to the scope of practice, differentiate pathology from normal aging, utilize evidence-based respiratory positioning, and apply restraints only as an absolute last resort.

Key Concept

Basic care and comfort for an agitated, bedbound client includes maintaining skin integrity, promoting optimal respiratory positioning, and utilizing non-pharmacological interventions to reduce sensory overload while strictly adhering to safety and delegation principles.

An older adult client with severe osteoarthritis and mild dementia resides in a long-term care facility. During early morning rounds, the client becomes verbally agitated and physically resists when staff attempt to change the bed linens and assist with dressing. Recognizing that joint stiffness is a primary contributing factor, which action should the nurse take?

Show answer & explanation

Answer: Apply warm, moist heat packs to the client's major joints prior to continuing the morning routine.

Answer

Apply warm, moist heat packs to the client's major joints prior to continuing the morning routine.
The correct answer addresses the root cause of the client's resistance. In clients with osteoarthritis, joint stiffness is typically most severe in the morning. Applying warm, moist heat is a standard, effective non-pharmacological comfort measure that increases blood flow, reduces muscle tension, and alleviates joint stiffness. By managing the physical discomfort first, the nurse can safely proceed with necessary basic care activities while reducing the client's agitation.

Step-by-Step Solution

1
Analyze the client's behavioral presentation in the context of their medical history.
The agitation and resistance to care are identified as behavioral expressions of physical pain caused by morning osteoarthritis stiffness.
Clients with dementia often express physical discomfort through resistance rather than verbally articulating their pain.
2
Determine the most appropriate basic care and comfort intervention.
Applying warm, moist heat is selected to directly address the physiological source of the discomfort.
Heat therapy promotes muscle relaxation, increases local tissue circulation, and effectively relieves osteoarthritic joint stiffness, which facilitates safer and more comfortable hygiene care.

Key Concept

A nurse is evaluating a 6868-year-old client who underwent a left-sided thoracentesis 22 hours ago for the treatment of a large pleural effusion secondary to heart failure. Which of the following assessment findings indicate a potential life-threatening complication and require immediate intervention? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Asymmetrical chest wall expansion with diminished breath sounds on the left side; A narrowing pulse pressure accompanied by a steady increase in resting heart rate; Sudden development of a severe, continuous cough producing pink, frothy sputum

Answer

The correct findings that indicate life-threatening complications are asymmetrical chest wall expansion with diminished breath sounds, a narrowing pulse pressure with an increasing heart rate, and a severe cough producing pink, frothy sputum.
A thoracentesis carries risks of severe physiological complications, primarily pneumothorax, hemothorax leading to hypovolemic shock, and re-expansion pulmonary edema. Asymmetrical chest expansion and diminished breath sounds on the affected side are classic indicators of a pneumothorax, which can rapidly progress to a tension pneumothorax. A narrowing pulse pressure combined with a steadily increasing resting heart rate represents the body's compensatory mechanism during early hypovolemic or hemorrhagic shock. Finally, the sudden development of a severe, continuous cough producing pink, frothy sputum is the hallmark sign of re-expansion pulmonary edema, a medical emergency that can occur when a large volume of fluid is rapidly drained from the pleural space. All three of these findings indicate impending physiological decompensation and demand immediate intervention.

Step-by-Step Solution

1
Identify the procedure performed and its associated high-risk complications.
The client had a thoracentesis. Major complications include pneumothorax, hemothorax, hypovolemic shock, and re-expansion pulmonary edema.
Recognizing procedure-specific risks is essential for targeted post-operative assessment.
2
Evaluate each assessment finding against the known complications.
Asymmetrical chest expansion and decreased breath sounds indicate pneumothorax. Narrowing pulse pressure and tachycardia suggest early shock. Pink, frothy sputum with a severe cough indicates re-expansion pulmonary edema.
Matching clinical signs to pathophysiology determines which findings are life-threatening.
3
Differentiate expected post-procedure findings from abnormal ones.
Normal ABG values and mild, localized pain at the puncture site are expected or non-emergent findings that do not require immediate life-saving intervention.
Prioritization requires distinguishing between stable/expected outcomes and physiological decompensation.

Key Concept

Early recognition of thoracentesis complications (pneumothorax, shock, pulmonary edema) is critical for reducing the risk of physiological decompensation.
Question 53Question →

A client who is admitted with severe gastrointestinal bleeding is receiving a unit of packed red blood cells (PRBCs) through a peripheral intravenous (IV) catheter. Fifteen minutes into the infusion, the client suddenly reports severe lower back pain, chills, and shortness of breath. The nurse suspects an acute hemolytic transfusion reaction. Place the following nursing interventions in the correct chronological order of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a suspected hemolytic transfusion reaction is: 1) Stop the transfusion immediately, 2) Disconnect the blood tubing and initiate normal saline with new tubing, 3) Assess vital signs and respiratory status, 4) Notify the healthcare provider and blood bank, 5) Return the blood product and tubing to the blood bank, and 6) Obtain a urine specimen.
When an acute hemolytic transfusion reaction occurs, the immediate priority is to stop the administration of the offending antigen to limit the severity of the immune response. Following this, the nurse must ensure a patent IV line is maintained using normal saline and entirely new tubing; flushing the old tubing would administer more incompatible blood. Once the immediate threat is contained and access is secured, the nurse performs a focused physiological assessment to guide emergency medical interventions. Only after the client's current status is known should the nurse notify the healthcare provider and the blood bank, as the provider will need the assessment data to prescribe treatment. Returning the blood product and obtaining a urine specimen are critical diagnostic steps but are lower in immediate priority compared to client stabilization.

Step-by-Step Solution

1
Stop the transfusion immediately.
The infusion of the potentially incompatible blood product is halted.
Prevents further exposure to the offending antigen and limits the severity of the reaction.
2
Disconnect the blood tubing and connect new IV tubing primed with 0.9% sodium chloride.
Intravenous access is maintained with a safe fluid without introducing residual blood.
Flushing the existing tubing would force the remaining incompatible blood into the client. New tubing ensures safety while keeping the vein open for emergency drugs.
3
Assess the client's vital signs and respiratory status.
A focused clinical picture of the client's physiological compromise is obtained.
Determines the immediate clinical needs (e.g., hypotension, hypoxia) and provides essential data to report to the healthcare provider.
4
Notify the healthcare provider and the blood bank.
The medical team is alerted, and the facility's transfusion reaction protocol is activated.
Facilitates medical intervention and initiates the necessary laboratory investigations.
5
Return the blood bag and tubing to the blood bank.
The physical evidence of the transfusion is secured by the laboratory.
Allows the laboratory to re-crossmatch the blood, perform bacterial cultures, and identify the exact cause of the incompatibility.
6
Obtain a urine specimen.
A sample is sent to the laboratory for urinalysis.
Assesses for hemoglobinuria, which confirms the destruction of red blood cells (hemolysis) and helps evaluate potential renal damage.

Key Concept

Management of an acute hemolytic transfusion reaction requires the immediate cessation of the blood product and maintenance of IV access using entirely new tubing and normal saline, followed by thorough assessment, provider notification, and diagnostic evaluation.
Question 54Question →

A nurse is monitoring a client who recently underwent endoscopic band ligation for bleeding esophageal varices. Which assessment findings should the nurse identify as early indicators of systemic physiological deterioration and impending hypovolemic shock? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: New-onset restlessness and frequent, purposeless movements; Urine output of 15 mL over the past hour; Respiratory rate increasing from 16 to 28 breaths per minute

Answer

The early indicators of impending hypovolemic shock include new-onset restlessness, decreased urine output (15 mL/hr), and increased respiratory rate (28 breaths/min).
In the early, compensatory stage of hypovolemic shock due to acute blood loss, the sympathetic nervous system activates to maintain cardiac output. This physiological adaptation includes shunting blood away from non-vital organs (causing oliguria), increasing respiratory drive to maximize oxygenation (tachypnea), and early signs of reduced cerebral perfusion (manifesting as restlessness, anxiety, or subtle agitation). Recognizing these subtle cues is critical for early intervention before profound cardiovascular collapse occurs.

Step-by-Step Solution

1
Analyze the client's clinical context.
The client is post-endoscopic band ligation for varices, placing them at extremely high risk for recurrent gastrointestinal hemorrhage and hypovolemic shock.
Establishing the primary physiological threat directs the focus to assessing hemodynamic stability and tissue perfusion.
2
Identify the compensatory mechanisms triggered during early (stage I/II) shock.
The body activates the sympathetic nervous system, leading to tachycardia, tachypnea, peripheral vasoconstriction, decreased renal perfusion, and altered cerebral oxygenation.
Early recognition relies on detecting these subtle compensatory shifts before a profound drop in blood pressure occurs.
3
Evaluate each assessment finding against anticipated shock physiology.
Restlessness (cerebral hypoxia), oliguria (renal conservation), and tachypnea (respiratory compensation) align with early shock. Widened pulse pressure, metabolic alkalosis, and a scratchy throat do not.
Differentiating between compensatory clinical signs and expected procedural side effects prevents failure to rescue.

Question 55Question →

A client recovering from a massive anterior wall myocardial infarction is being monitored with a pulmonary artery catheter. Over the last hour, the client has become increasingly lethargic. The nurse evaluates the following hemodynamic and laboratory parameters:

- Heart rate: 118118 beats/min
- Mean arterial pressure (MAP): 5454 mm Hg
- Central venous pressure (CVP): 1616 mm Hg (Normal: 22-88 mm Hg)
- Pulmonary artery wedge pressure (PAWP): 2424 mm Hg (Normal: 66-1212 mm Hg)
- Cardiac index (CI): 1.71.7 L/min/m 2^2 (Normal: 2.52.5-4.04.0 L/min/m 2^2)
- Systemic vascular resistance (SVR): 2150 dynes/sec/cm−52150 \text{ dynes/sec/cm}^{-5} (Normal: 800800-1200 dynes/sec/cm−51200 \text{ dynes/sec/cm}^{-5})

Arterial blood gas (ABG) results on a 40%40\% Venturi mask reveal: pH 7.247.24, PaCO 2_2 5858 mm Hg, HCO 3−_3^- 2525 mEq/L, and PaO 2_2 5858 mm Hg.

Based on this physiological presentation, which intervention most accurately addresses the primary pathophysiological failure?

Show answer & explanation

Answer: Administering an inotropic agent combined with a loop diuretic to improve myocardial contractility and reduce cardiac filling pressures.

Answer

The correct intervention is administering an inotropic agent combined with a loop diuretic to improve myocardial contractility and reduce cardiac filling pressures.
The client is in severe cardiogenic shock, evidenced by a profoundly depressed cardiac index, elevated left-sided filling pressures (PAWP), and a compensatory severe elevation in systemic vascular resistance (SVR). The failure of the left ventricle to pump effectively has caused fluid to back up into the pulmonary vasculature, resulting in alveolar flooding (pulmonary edema). This fluid barrier impairs gas exchange, directly leading to severe hypoxemia and acute uncompensated respiratory acidosis. The priority physiological intervention is to concurrently enhance myocardial contractility using positive inotropes and reduce the volume overload (preload) with loop diuretics. This combined approach improves forward blood flow, reduces the pulmonary hydrostatic pressure, and ultimately relieves the respiratory failure.

Step-by-Step Solution

1
Analyze the hemodynamic profile to determine the specific shock state.
The depressed cardiac index (1.71.7), highly elevated filling pressures (CVP 1616, PAWP 2424), and compensatory severe vasoconstriction (SVR 21502150) confirm cardiogenic shock with severe left ventricular failure.
Accurately identifying the shock etiology dictates the necessary physiological interventions and rules out contraindications like fluid boluses.
2
Interpret the arterial blood gas (ABG) findings.
The low pH (7.247.24), elevated PaCO 2_2 (5858), and normal HCO 3−_3^- (2525) indicate acute, uncompensated respiratory acidosis.
Determining the exact acid-base imbalance prevents the administration of inappropriate metabolic treatments such as sodium bicarbonate.
3
Synthesize the data to identify the primary pathophysiological cascade.
Myocardial pump failure has caused blood to back up into the pulmonary vasculature (high PAWP), resulting in alveolar flooding (pulmonary edema), which in turn causes impaired gas exchange, hypoxemia, and carbon dioxide retention.
Understanding the cause-and-effect relationship between cardiac failure and respiratory compromise is essential for clinical prioritization.
4
Select the pharmacological intervention that targets the root physiological cause.
Inotropes increase forward blood flow (contractility), and loop diuretics reduce the fluid overload (preload), thereby resolving both the primary shock state and the secondary respiratory acidosis.
Treatments must address pump efficiency and fluid volume simultaneously without increasing the cardiac workload (afterload).

The nurse is preparing to transfer a client with right-sided hemiparesis from the bed to a wheelchair. To promote a safe transfer, where should the nurse position the wheelchair?

Show answer & explanation

Answer: On the client's left side, angled slightly toward the bed

Answer

The wheelchair should be positioned on the client's left side, angled slightly toward the bed.
The correct nursing action is to position the wheelchair on the client's strong side (the left side, in this scenario). This allows the client to bear weight on their unaffected leg, safely pivot, and use their strong left arm to reach for the wheelchair's armrest, ensuring a stable and secure transfer.

Step-by-Step Solution

1
Identify the client's strong and weak sides based on the clinical presentation.
The client has right-sided hemiparesis, meaning the right side is weak and the left side is strong.
Safe transfer techniques require utilizing the client's functioning extremities to maintain balance and bear weight.
2
Apply the core principle of bed-to-chair transfers for clients with unilateral weakness.
The transfer should always be directed toward the client's strong side.
Transferring toward the strong side allows the client to pull themselves toward the chair using their strong arm and pivot securely on their strong leg.
3
Determine the optimal placement for the wheelchair.
The wheelchair must be placed on the left side, angled appropriately.
This alignment provides the shortest, safest pivoting distance for the client.

A nurse is creating a plan of care for an older adult client who is on strict bed rest and is at high risk for skin breakdown. Which of the following actions are appropriate to promote basic care and comfort? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Reposition the client at least every 2 hours to relieve pressure on vulnerable areas.; Use pillows to float the client's heels completely off the mattress surface.; Apply a moisture barrier ointment to the perineal skin after cleansing episodes of incontinence.

Answer

The appropriate actions are repositioning the client at least every 2 hours, using pillows to float the heels, and applying a moisture barrier ointment to the perineal skin.
The correct interventions directly address the hazards of immobility by reducing prolonged pressure on bony prominences (through frequent repositioning and floating heels) and protecting the skin from moisture-associated damage (using barrier creams). These are standard, effective basic care measures.

Step-by-Step Solution

1
Identify the client's primary risks based on the scenario.
The client is an older adult on strict bed rest, making them highly vulnerable to pressure injuries, skin maceration, and complications of immobility.
Understanding the client's vulnerability is necessary to select effective basic care and comfort measures.
2
Evaluate each nursing intervention for safety, efficacy, and scope of practice.
Repositioning, floating heels, and applying moisture barriers are safe, evidence-based nursing interventions. Delegating assessments, using high Fowler's continuously, and ignoring acute symptoms are unsafe or inappropriate.
To ensure the selected interventions actively promote comfort and prevent harm while adhering to nursing standards.

A nurse is caring for a 58-year-old client who returned to the unit two hours ago following a percutaneous liver biopsy. The client reports mild right upper quadrant pain. The current vital signs are: blood pressure 98/60 mm Hg, heart rate 112 beats/min, and respiratory rate 20 breaths/min. Which action should the nurse take immediately to minimize the client's physiological risk?

Show answer & explanation

Answer: Place the client in a right side-lying position and notify the healthcare provider of the vital sign trends.

Answer

Place the client in a right side-lying position and notify the healthcare provider of the vital sign trends.
After a percutaneous liver biopsy, the client is at a high risk for hemorrhage. Positioning the client on the right side applies direct pressure to the liver capsule against the chest wall, promoting hemostasis and reducing the risk of bleeding. Furthermore, the client's tachycardia and borderline low blood pressure are early physiological indicators of hypovolemic shock, meaning the healthcare provider must be notified immediately to initiate further interventions.

Step-by-Step Solution

1
Analyze the client's vital signs and clinical presentation.
The resting heart rate of 112 beats/min and blood pressure of 98/60 mm Hg are identified as abnormal indicators of possible internal hemorrhage.
Recognizing early signs of hypovolemic shock is critical for post-procedure risk reduction.
2
Determine the appropriate physical positioning for a post-liver biopsy client.
The right side-lying position is required.
Applying direct physical pressure to the biopsy site against the chest wall promotes hemostasis and prevents bleeding.
3
Formulate the immediate nursing intervention.
The nurse must simultaneously correct the client's position for hemostasis and escalate the assessment findings to the provider.
Prompt medical intervention and ongoing monitoring are necessary to manage suspected bleeding.

An adult client is receiving care in the emergency department for a severe asthma exacerbation. The initial arterial blood gas (ABG) on room air indicated pH=7.48\text{pH} = 7.48, PaCO2=28 mm Hg\text{PaCO}_2 = 28 \text{ mm Hg}, and HCO3−=23 mEq/L\text{HCO}_3^- = 23 \text{ mEq/L}. Two hours later, the nurse observes that the client has become extremely lethargic and their respiratory effort has noticeably decreased. A follow-up ABG reveals pH=7.29\text{pH} = 7.29, PaCO2=56 mm Hg\text{PaCO}_2 = 56 \text{ mm Hg}, and HCO3−=24 mEq/L\text{HCO}_3^- = 24 \text{ mEq/L}. Which action is the highest priority for the nurse to take?

Show answer & explanation

Answer: Activate the rapid response team and prepare for immediate airway management.

Answer

Activate the rapid response team and prepare for immediate airway management.
The correct action is to activate the rapid response team and prepare for advanced airway management. During an acute asthma attack, clients initially hyperventilate, blowing off CO2\text{CO}_2 and causing respiratory alkalosis. If the client becomes fatigued, their respiratory rate and depth decrease, leading to CO2\text{CO}_2 retention, hypercapnia, and respiratory acidosis. In the context of a severe asthma exacerbation, new-onset lethargy combined with a rising PaCO2\text{PaCO}_2 is an ominous sign of impending respiratory failure and requires immediate mechanical ventilation.

Step-by-Step Solution

1
Analyze the initial ABG results.
pH=7.48\text{pH} = 7.48 (alkalosis) and PaCO2=28\text{PaCO}_2 = 28 (low) indicate respiratory alkalosis, which is expected early in an asthma attack due to rapid breathing and hyperventilation.
Establishing the baseline helps identify clinical trends.
2
Analyze the follow-up ABG results and clinical presentation.
pH=7.29\text{pH} = 7.29 (acidosis) and PaCO2=56\text{PaCO}_2 = 56 (high) indicate uncompensated respiratory acidosis. The client is now lethargic with decreased respiratory effort.
Correlating laboratory values with physical symptoms is essential for accurate clinical judgment.
3
Synthesize the findings to determine the client's physiological state.
The transition from alkalosis to acidosis in asthma signifies that the client's respiratory muscles are severely fatigued. They can no longer maintain the work of breathing, leading to CO2\text{CO}_2 retention and impending respiratory arrest.
Recognizing this classic pattern of physiological decompensation dictates the urgency of the required intervention.
4
Select the highest priority intervention.
Activating the rapid response team for advanced airway management (intubation and mechanical ventilation) is the critical life-saving action.
Airway and Breathing take absolute priority (ABCs) over further assessment or incorrect pharmacological treatments.

Key Concept

Impending respiratory failure in asthma is characterized by a transition from respiratory alkalosis to respiratory acidosis due to muscle fatigue, requiring immediate mechanical ventilation.

A client with a newly casted right fractured tibia is prescribed non-weight-bearing status for the right leg. The nurse is educating the client on how to safely stand up from a wheelchair using axillary crutches. In which order should the nurse instruct the client to perform the following actions? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first move to the edge of the chair with the unaffected foot flat, hold both crutches in the hand of the affected side, place the unaffected hand on the armrest, push up using the unaffected arm and leg, and finally transfer the crutches into the tripod position.
Standing safely with crutches requires maximizing the strength of the unaffected limbs. The client must position themselves at the edge of the seat with the strong foot grounded. By holding both crutches on the affected side, the strong arm is free to push off the armrest simultaneously with the strong leg. Once standing and balanced, the crutches are repositioned under both arms.

Step-by-Step Solution

1
Slide to the front edge of the wheelchair.
The client's center of gravity is shifted forward.
Proper positioning is required to allow the strong leg to bear the full body weight during the lift.
2
Hold both crutches in the right hand.
The crutches are secured on the side of the affected leg.
This leaves the strong, unaffected arm free to push off the chair while the crutches provide support on the weaker side.
3
Place the left hand on the left armrest.
The client is anchored for the lift.
The unaffected arm has the strength required to assist the unaffected leg in lifting the body's entire weight.
4
Push up to a stand using the left arm and left leg.
The client rises to a standing position.
Weight is strictly kept off the right fractured tibia, maintaining the prescribed non-weight-bearing status.
5
Position one crutch on each side to form a tripod stance.
The client is balanced and ready to ambulate.
The tripod position provides a wide base of support necessary for safe mobilization.
