Question

A nurse is reviewing prescribed medications for a patient who presents to the emergency department with acute facial swelling, hoarseness, and difficulty breathing. The nurse recognizes these findings as laryngeal obstruction caused by angioedema. Which medication class is most likely associated with this adverse effect?

Answer 1

Correct Answers:

Angiotensin-converting enzyme (ACE) inhibitors

Rationale :

🔶 ACE inhibitors are well known to cause angioedema, a potentially life-threatening adverse reaction characterized by facial swelling, hoarseness, and airway compromise.

🔶 This reaction occurs because ACE inhibitors block the breakdown of bradykinin, leading to increased vascular permeability and tissue swelling.

🔶 Laryngeal involvement can rapidly progress to airway obstruction, making this a medical emergency requiring immediate intervention.

🔶 Angioedema associated with ACE inhibitors may occur even after long-term therapy and is not always dose-dependent.

🔶 Recognizing this medication class is critical because the drug must be discontinued immediately to prevent recurrence of severe airway compromise.

❌ Incorrect Options Explained

Calcium channel blockers

These medications primarily affect vascular smooth muscle and heart contractility. They are not commonly associated with bradykinin-mediated angioedema.

Loop diuretics

Loop diuretics can cause electrolyte imbalance and dehydration but are not linked to acute laryngeal swelling. Their adverse effects are unrelated to airway obstruction.

Beta-adrenergic blockers

Beta-blockers affect heart rate and blood pressure. They do not increase bradykinin levels or typically cause angioedema.

Answer 2

Correct Answers:

Older adults with pneumonia are often afebrile.

Rationale :

🔷 Older adults frequently have a blunted immune response, which limits their ability to mount a typical febrile reaction during infection.

🔷 Pneumonia in elderly clients often presents with confusion, weakness, tachycardia, and tachypnea rather than fever.

🔷 A normal temperature in this age group does not rule out serious infection because thermoregulation becomes less effective with aging.

🔷 The presence of altered mental status may actually be the earliest and most significant sign of infection in older adults.

🔷 Recognizing atypical presentations prevents delayed treatment of potentially life-threatening conditions such as sepsis.

❌ Incorrect Options Explained

The pneumonia diagnosis is unlikely without a fever.

Fever is not required for infection diagnosis in older adults. Many elderly clients remain afebrile despite serious infection.

The thermometer reading is probably inaccurate.

There is no evidence the thermometer is malfunctioning. Afebrile presentation is common in geriatric infections.

The temperature indicates the infection is resolving.

A normal temperature does not confirm improvement. Other clinical indicators must be evaluated to determine resolution.

Answer 3

Correct Answers:

Dilutes excess bicarbonate and restores chloride levels

Rationale :

💠 Metabolic alkalosis is commonly caused by loss of hydrogen ions or excess bicarbonate in the bloodstream.

💠 Administration of intravenous normal saline (0.9% NaCl) helps correct alkalosis by restoring chloride levels, which promotes renal excretion of bicarbonate.

💠 Increased chloride availability allows the kidneys to exchange bicarbonate for chloride, reducing serum bicarbonate concentration.

💠 The isotonic fluid also expands intravascular volume, improving renal perfusion and enhancing acid-base correction.

💠 This mechanism directly addresses the underlying electrolyte imbalance rather than altering respiratory compensation.

❌ Incorrect Options Explained

Stimulates the respiratory rate to eliminate excess bicarbonate

Respiratory rate affects carbon dioxide levels, not bicarbonate elimination. The respiratory system compensates for metabolic disturbances but does not directly remove bicarbonate.

Increases carbon dioxide retention to lower pH

Carbon dioxide retention would worsen acidosis, not correct alkalosis. This is not the mechanism of normal saline therapy.

Promotes renal potassium excretion to reduce alkalosis

Potassium balance is important but does not explain the primary corrective mechanism of chloride replacement in alkalosis.

Answer 4

Correct Answers:

Repeat the pain assessment to clarify the discrepancy between the patient's behavior and reported pain score.

Rationale :

🔵 Pain is a subjective experience, and the patient’s self-report is considered the most reliable indicator of pain intensity.

🔵 However, when there is a discrepancy between objective findings (grimacing, guarding) and a reported pain score of 1/10, further clarification is required.

🔵 The nurse should reassess using open-ended questions to explore the quality, location, and intensity of pain, ensuring accurate assessment before intervention.

🔵 Immediate medication administration without clarification may lead to overtreatment or misinterpretation of symptoms.

🔵 Accurate reassessment supports individualized care and ensures documentation reflects the client’s true pain experience.

❌ Incorrect Options Explained

Reassess the pain in 30 minutes to allow time for any changes.

Delaying reassessment ignores the current inconsistency between observed behaviors and reported pain level. Immediate clarification is more appropriate.

Document the pain score as reported without further action.

Simply documenting the pain score fails to address the conflicting nonverbal cues. The nurse must investigate discrepancies to ensure accurate assessment.

Administer pain medication immediately based on objective indicators of pain.

Pain medication should not be given solely on behavioral cues without confirming the patient’s perception. The patient’s self-report remains the priority standard.

Answer 5

Correct Answers:

“I have severe, sharp, knifelike chest pain on one side that gets worse when I take a deep breath."

Rationale :

🟣 Pleurisy is inflammation of the pleural membranes surrounding the lungs, which causes pain when the layers rub against each other during breathing.

🟣 The pain is typically sharp, stabbing, or knifelike and is localized to one side of the chest.

🟣 It worsens with deep inspiration, coughing, or movement, because these actions increase pleural friction.

🟣 Clients often report guarding and shallow breathing to minimize discomfort.

🟣 Recognizing this classic pleuritic chest pain pattern helps differentiate it from cardiac or gastrointestinal causes of chest pain.

❌ Incorrect Options Explained

"It feels like a dull, heavy pressure in my chest that spreads to my arm."

This description is more characteristic of myocardial ischemia or angina. Cardiac pain often radiates to the arm or jaw and is described as pressure.

"It's a burning sensation that spreads across my chest that improves when I lie flat."

Burning pain may suggest gastrointestinal causes such as reflux. Pleuritic pain typically worsens, not improves, with positional changes related to breathing.

"It feels like soreness in my chest that stays the same when I breath in and out."

Pleurisy pain changes with respiration. Constant pain unaffected by breathing suggests a different etiology.

Answer 6

Correct Answers:

The patient's pain threshold may be elevated, potentially masking mild pain sensations.

Rationale :

🔴 Aging is associated with changes in the central and peripheral nervous system, which can alter pain perception and response.

🔴 Older adults may have an elevated pain threshold, meaning stronger stimuli are required before pain is perceived.

🔴 This alteration can result in underreporting or delayed recognition of mild or early pain, leading to untreated discomfort.

🔴 Chronic conditions may further complicate assessment because gradual adaptation can blunt symptom awareness.

🔴 Understanding that pain perception may be diminished helps the nurse conduct a thorough assessment and avoid undertreating pain in the older adult population.

❌ Incorrect Options Explained

The patient's gender is the primary determinant of pain perception in older adults.

Gender can influence pain expression, but it is not the most relevant age-related physiological factor. Neurological changes associated with aging are more clinically significant in this scenario.

Cultural background is the most critical factor influencing pain reporting in older adults.

Culture affects pain expression and reporting patterns, but the question specifically addresses age-related physiological changes. Neurobiological aging plays a more central role here.

Past painful experiences will always result in increased pain tolerance in older adults.

Past experiences may influence coping mechanisms, but they do not universally increase tolerance. Pain response remains individualized and variable.

Answer 7

Correct Answers:

Low-grade fever with diminished breath sounds at the lung bases

Rationale :

🟢 Atelectasis occurs when alveoli collapse, commonly within the first 24–48 hours after thoracic surgery.

🟢 It often presents early with diminished breath sounds at the lung bases due to reduced air movement.

🟢 A low-grade fever is a classic early postoperative finding related to alveolar collapse and retained secretions.

🟢 Shallow breathing from pain decreases lung expansion, increasing risk for atelectasis.

🟢 Early recognition allows prompt intervention with incentive spirometry, coughing, deep breathing, and ambulation to prevent pneumonia.

❌ Incorrect Options Explained

Bilateral wheezing that improves after bronchodilator therapy

Wheezing suggests bronchospasm or airway constriction, more consistent with asthma or COPD. Atelectasis typically presents with decreased breath sounds rather than wheezing.

Sudden onset of high fever and purulent sputum

These findings are more characteristic of pneumonia. Atelectasis presents earlier and usually with low-grade fever.

Severe chest pain with frothy pink sputum

Frothy pink sputum is a hallmark sign of pulmonary edema. This finding indicates fluid in the alveoli rather than collapse.

Answer 8

Correct Answers:

The patient's pain threshold may be elevated, potentially masking mild pain sensations.

Rationale :

🔷 Aging is associated with physiological changes in the peripheral and central nervous systems, which can alter how pain is perceived and processed.

🔷 Older adults often demonstrate an elevated pain threshold, meaning a stronger stimulus is required before pain is recognized.

🔷 Because of this change, mild or early pain may be underreported or unnoticed, especially in chronic conditions like joint disease.

🔷 Delayed pain perception can lead to progression of pathology before symptoms are clearly expressed, complicating pain management planning.

🔷 Recognizing this age-related change allows the nurse to conduct more detailed assessments and avoid undertreating pain in the elderly population.

Answer 9

Correct Answers:

Cerebral edema resulting from worsening hyponatremia

Rationale :

🔶 A serum sodium level of 130 mEq/L indicates hyponatremia, which reflects a decreased concentration of sodium in the extracellular fluid.

🔶 Administration of hypotonic intravenous fluids further lowers serum osmolality, causing water to shift into cells through osmosis.

🔶 When this fluid shift occurs in brain cells, it leads to cerebral edema, which increases intracranial pressure and can impair neurological function.

🔶 Early manifestations may include headache, confusion, restlessness, and nausea, but progression can result in seizures, coma, and respiratory arrest.

🔶 Because the brain is confined within the skull, swelling poses an immediate life-threatening risk, making close neurological monitoring the top priority.

❌ Incorrect Options Explained

Hyperkalemia caused by electrolyte imbalance

Hyponatremia does not directly cause elevated potassium levels. Sodium and potassium are regulated independently through different physiological mechanisms.

Pulmonary edema due to fluid overload

While fluid overload can cause pulmonary edema, hypotonic fluids primarily create intracellular fluid shifts rather than immediate fluid accumulation in the lungs. The most critical risk in worsening hyponatremia is neurological compromise.

Metabolic alkalosis due to fluid shifts

Hyponatremia affects sodium balance and fluid distribution, not acid-base balance. Metabolic alkalosis is unrelated to hypotonic fluid administration in this context.

Answer 10

Correct Answers:

Using a transcutaneous electrical nerve stimulation (TENS) unit

Rationale :

🔵 Dosing guided imagery techniques with the patient

🔵 Guided imagery is a cognitive-behavioral intervention that helps reduce pain perception by redirecting attention away from discomfort.

🔵 It activates the parasympathetic nervous system, promoting relaxation and reducing stress-related muscle tension.

🔵 This technique decreases the brain’s interpretation of pain signals through distraction and mental visualization.

🔵 Guided imagery is especially effective when combined with pharmacologic therapy because it enhances overall pain control.

🔵 It is safe, inexpensive, and appropriate for postoperative patients experiencing moderate pain.

🔵 Using Ice Therapy

🔵 Ice therapy (cryotherapy) reduces pain by causing vasoconstriction, which decreases inflammation and edema at the surgical site.

🔵 Cold application slows nerve conduction velocity, reducing transmission of pain signals.

🔵 It is particularly beneficial during the acute postoperative period when swelling contributes to discomfort.

🔵 Ice therapy complements analgesics by targeting the inflammatory component of pain.

🔵 Proper application intervals (typically 15–20 minutes at a time) help prevent tissue injury.

🔵 Using a transcutaneous electrical nerve stimulation (TENS) unit

🔵 A TENS unit delivers low-voltage electrical stimulation to sensory nerves to reduce pain perception.

🔵 It works through the gate control theory of pain, which blocks transmission of painful stimuli to the brain.

🔵 TENS may also stimulate endorphin release, providing additional analgesic effects.

🔵 It is noninvasive and commonly used as an adjunct to pharmacologic therapy for postoperative pain.

🔵 When properly applied, it enhances comfort without increasing medication dosage.

❌ Incorrect Options Explained

Administering patient-controlled analgesia (PCA)

PCA is a pharmacologic intervention that allows patients to self-administer opioid medication. The question specifically asks for nonpharmacologic strategies.

Encouraging patient to perform high-impact aerobic exercises

High-impact exercise is inappropriate immediately postoperatively and may worsen pain or disrupt healing. Early mobility is encouraged, but strenuous activity is not a pain management strategy.
