A nurse is caring for an 8-year-old male client admitted to the surgical unit after having a total right knee replacement.
The nurse reviews the client's nursing note, vital signs, and medication administration record (MAR). Based on the findings, which medication is considered an anti-emetic?
Ondansetron (Zofran).
Acetaminophen (Tylenol).
Prochlorperazine (Compazine).
Morphine Sulfate.
The Correct Answer is A
Choice A rationale
Ondansetron (Zofran) is an anti-emetic medication used to prevent nausea and vomiting by blocking serotonin receptors in the chemoreceptor trigger zone and the gastrointestinal tract.
Choice B rationale
Acetaminophen (Tylenol) is an analgesic and antipyretic medication used to relieve pain and reduce fever, but it is not an anti-emetic.
Choice C rationale
Prochlorperazine (Compazine) is an anti-psychotic and anti-emetic medication used to treat nausea and vomiting, as well as certain mental/mood disorders.
Choice D rationale
Morphine Sulfate is an opioid analgesic used to relieve moderate to severe pain but does not have anti-emetic properties.

Correct Answer is A
Explanation
Choice A rationale
Ciprofloxacin is a bactericidal antibiotic that works by inhibiting DNA gyrase, an enzyme necessary for DNA replication in bacteria. This prevents bacterial cells from replicating and ultimately leads to their death.
Choice B rationale
Ciprofloxacin does not accelerate bacterial growth; instead, it inhibits growth by preventing DNA replication.
Choice C rationale
Ciprofloxacin is not a diuretic. Diuretics work on the kidneys to increase urine production, but ciprofloxacin targets bacterial DNA replication.
Choice D rationale
Ciprofloxacin is not a beta-blocker and does not lower heart rate or blood pressure. Beta-blockers work by blocking beta-adrenergic receptors in the heart.
Correct Answer is B
Explanation
Choice A rationale
Dextromethorphan is not used for asthma. Asthma treatment typically involves bronchodilators and anti-inflammatory medications.
Choice B rationale
Dextromethorphan is an antitussive used to suppress coughing. It acts on the cough center in the brain to reduce the urge to cough.
Choice C rationale
This medication is not used for pain reduction. Pain management usually involves analgesics or anti-inflammatory drugs.
Choice D rationale
Dextromethorphan is not indicated for allergic rhinitis. Allergic rhinitis treatments typically include antihistamines or nasal corticosteroids.
