6. Respiratory and Anti-inflammatory Agents
1. A 68-year-old patient with heart failure and a history of asthma is initiated on a new beta-blocker
therapy. Which agent is most appropriate to ensure therapeutic efficacy while minimizing the
risk of bronchospasm?
A. Propranolol
B. Metoprolol succinate
C. Nadolol
D. Carvedilol
Answer: B
CORRECT ANSWER : B
, Rationale: Metoprolol succinate is a cardioselective $\beta_1$ antagonist, which minimizes the
risk of bronchoconstriction in patients with underlying asthma by avoiding $\beta_2$ receptor
blockade. Propranolol and nadolol are non-selective and pose a high risk of bronchospasm,
while carvedilol provides combined $\alpha_1$ and non-selective $\beta$ blockade, also
increasing the risk of airway resistance.
2. A patient being treated for hypertension with lisinopril presents with a dry, persistent cough.
Which mechanism most accurately describes the etiology of this adverse effect?
A. Increased production of prostaglandins in the lung tissue
B. Accumulation of bradykinin due to ACE inhibition
C. Direct stimulation of airway sensory receptors by ACE inhibitors
D. Downregulation of angiotensin II receptors in the bronchial mucosa
Answer: B
CORRECT ANSWER : B
Rationale: ACE inhibitors inhibit the breakdown of bradykinin, a potent vasodilator and
inflammatory mediator that accumulates in the respiratory tract, leading to a dry cough.
Prostaglandins are generally protective, and neither direct stimulation nor receptor
downregulation serves as the primary pharmacological explanation for this specific adverse
effect.
3. A patient with type 2 diabetes mellitus is started on exenatide. Which therapeutic benefit beyond
glycemic control is a key characteristic of this medication class?
A. Increased appetite stimulation
B. Delayed gastric emptying leading to weight loss
C. Significant risk of hypoglycemia when used as monotherapy
D. Direct stimulation of pancreatic alpha cells
Answer: B
CORRECT ANSWER : B
Rationale: Exenatide is a GLP-1 receptor agonist that slows gastric emptying and increases
satiety, often resulting in weight loss, unlike sulfonylureas. It does not cause significant
hypoglycemia as monotherapy, and it inhibits, rather than stimulates, glucagon secretion from
alpha cells.
,4. A patient is prescribed spironolactone for the management of refractory heart failure. Which
electrolyte imbalance must the nurse monitor for most closely during the initial weeks of
therapy?
A. Hypokalemia
B. Hyponatremia
C. Hyperkalemia
D. Hypomagnesemia
Answer: C
CORRECT ANSWER : C
Rationale: Spironolactone is a potassium-sparing diuretic that acts as an aldosterone antagonist
in the distal tubule, promoting sodium excretion while retaining potassium. Consequently, the
risk of hyperkalemia is significantly elevated, requiring frequent monitoring, whereas
hypokalemia is a side effect of loop or thiazide diuretics.
5. When administering vancomycin, the nurse notes the patient has developed flushing,
hypotension, and pruritus of the upper body. What is the most appropriate nursing intervention?
A. Immediately administer an antihistamine and resume the infusion
B. Stop the infusion and assess the patient, then consider a slower infusion rate
C. Increase the rate of saline hydration to flush the medication
D. Conclude that the patient is having an anaphylactic reaction and administer epinephrine
Answer: B
CORRECT ANSWER : D
Rationale: These symptoms are characteristic of "Red Man Syndrome," a hypersensitivity
reaction related to the rate of vancomycin infusion, not an IgE-mediated anaphylactic reaction.
The infusion should be halted to alleviate symptoms, and subsequent doses should be
administered at a significantly slower rate.
6. A patient is initiated on warfarin therapy. Which monitoring parameter is essential to guide
dosage adjustments and assess therapeutic efficacy?
A. aPTT
, B. INR
C. Platelet count
D. Bleeding time
Answer: B
CORRECT ANSWER : B
Rationale: Warfarin exerts its anticoagulant effect by inhibiting vitamin K-dependent clotting
factors, and its therapeutic range is monitored via the International Normalized Ratio (INR).
aPTT is used for heparin monitoring, while platelet count is used to monitor for heparin-induced
thrombocytopenia.
7. A patient with severe rheumatoid arthritis is started on methotrexate. Which supplement is
commonly prescribed concurrently to mitigate toxic side effects?
A. Vitamin B12
B. Folic acid
C. Iron sulfate
D. Calcium carbonate
Answer: B
CORRECT ANSWER : B
Rationale: Methotrexate is a folate antagonist; administering supplemental folic acid helps
reduce common adverse effects such as stomatitis, myelosuppression, and hepatotoxicity. The
other supplements do not counteract the mechanism of folate depletion caused by methotrexate.
8. An elderly patient is prescribed a benzodiazepine for sleep disturbances. Why is this drug class
generally discouraged for the geriatric population?
A. Increased risk of cognitive impairment and falls
B. High potential for inducing metabolic acidosis
C. Direct inhibition of hepatic drug metabolism
D. Ineffectiveness in long-term insomnia management
Answer: A
