1 A patient is prescribed salmeterol for treatment of exercise-induced asthma. What is
the recommended dosing schedule according to asthma experts?
A Immediately after exercise
B 30 minutes before exercise to prevent bronchoconstriction
C 2 hours before exercise
D Only after symptoms occur
Why B is correct: Salmeterol should be taken 30 minutes before exercise to prevent
exercise-induced bronchoconstriction.
A — Taking after exercise does not prevent bronchoconstriction.
C — 2 hours is too early; peak effect is needed during exercise.
D — Salmeterol is a preventive medication, not for acute symptom relief.

decongestant. What instructions should be given?
A Limit fluid intake
B Increase fluids to 2 L/day
C Use for 2 weeks minimum
D Discontinue if nasal burning occurs
Why B is correct: Increasing fluids to 2 L/day helps thin secretions and promotes sinus
drainage.
A — Fluid restriction is not recommended for sinusitis.
C — Nasal decongestants should be used short-term to avoid rebound congestion.
D — Mild burning may occur; discontinuation is not necessary.
3 A 71-year-old man with a history of heart disease and diabetes has had an
antihistamine prescribed. The nurse is concerned due to the risk of what?
A Hypoglycemia
B Cardiac arrhythmias
C Hypertension
D Respiratory depression
Why B is correct: Antihistamines can cause cardiac arrhythmias, especially in older adults
with underlying heart disease.

C — Hypotension is more common than hypertension.
D — Respiratory depression is not a typical effect of antihistamines.
