g g g g g g g g g g g g



relief of acute asthma symptoms. It works by relaxing the smooth muscles of the

airways, improving airflow during an asthma attack.

effect, so the nurse should monitor the patient's potassium levels and consider
g g g g g g g g g g g g



supplementation if necessary.

Rationale: Opioids, such as morphine, commonly cause constipation due to their
g g g g g g g g g g



effects on the gastrointestinal tract, which slows motility. Patients receiving
g g g g g g g g g g



opioids should be monitored for constipation and may require a stool softener or
g g g g g g g g g g g g



laxative.

g g g g




Rationale: Warfarin is an anticoagulant that affects clotting factors. The
g g g g g g g g g



prothrombin time (PT) and international normalized ratio (INR) are used to
g g g g g g g g g g g



monitor the therapeutic effect of warfarin. The INR should be within a therapeutic
g g g g g g g g g g g g



range (usually 2.0–3.0) for most conditions.

Answer: b) Fluoxetine g g




Rationale: Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) used

in the brain by inhibiting its reuptake, leading to mood improvement.
