,NR 293 Gas Exchange and Respiratory Pharmacology Quiz 2026/2027 UPDATE
1. A patient with acute exacerbation of asthma is admitted to the emergency department.
Which medication should the nurse prioritize for immediate administration?
A. Salmeterol
B. Montelukast
C. Fluticasone
D. Albuterol
Answer: D
Rationale: Albuterol is a short-acting beta-2 agonist (SABA) used as a rescue medication
for acute bronchospasm. Salmeterol is a long-acting beta agonist (LABA) and fluticasone is
a corticosteroid, neither of which are for acute relief.
2. The nurse is providing education to a patient prescribed theophylline. Which dietary
restriction is most important for this patient?
A. Grapefruit juice
B. Leafy green vegetables
C. Caffeine
D. High-protein meals
, Answer: C
Rationale: Caffeine is a methylxanthine, similar to theophylline. Consuming caffeine while
taking theophylline can increase the risk of toxicity and cause adverse effects like
tachycardia and CNS stimulation.
3. Which assessment finding in a patient taking theophylline indicates potential toxicity?
A. Serum levels of 12 mcg/mL
B. Increased appetite
C. Heart rate of 115 beats per minute
D. Constipation
Answer: C
Rationale: The therapeutic range for theophylline is 10-20 mcg/mL. Toxicity signs include
tachycardia, tremors, seizures, and arrhythmias.
4. A patient is prescribed both Albuterol and Beclomethasone inhalers. What instruction is
vital for the nurse to provide regarding administration?
A. Use the Beclomethasone first to reduce inflammation.
B. Wait 10 minutes between the two inhalers.
