A nurse is caring for a client who has a sulfonamide allergy. Which of the following medications should the nurse identify as contraindicated?
Famotidine
Aspirin
Metronidazole
Glyburide
The Correct Answer is D
A. Famotidine is an H2 receptor antagonist used to treat conditions like ulcers and gastroesophageal reflux disease (GERD). It does not contain sulfonamide and is generally safe for patients with sulfonamide allergies.
B. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief, fever reduction, and anti-inflammatory purposes. It does not contain sulfonamide and is not contraindicated for patients with sulfonamide allergies.
C. Metronidazole is an antibiotic used to treat various infections, including those of the gastrointestinal tract and the reproductive system. It does not contain sulfonamide and is safe for patients with sulfonamide allergies.
D. Glyburide is a sulfonylurea used to treat type 2 diabetes by increasing insulin production in the pancreas. It contains sulfonamide and can cause allergic reactions in patients with sulfonamide allergies, making it contraindicated.

Correct Answer is D
Explanation
A. Oxycodone promotes vasodilation of cranial arteries. This is not the primary mechanism by which oxycodone affects respiratory rate. Vasodilation of cranial arteries is not directly related to respiratory depression.
B. Oxycodone blocks the sodium channel suspending nerve conduction. This is not the primary mechanism of action for oxycodone. Oxycodone primarily acts on opioid receptors rather than sodium channels.
C. Oxycodone inhibits prostaglandin synthesis. This is not the primary mechanism of action for oxycodone. Inhibition of prostaglandin synthesis is more characteristic of nonsteroidal anti-inflammatory drugs (NSAIDs).
D. Oxycodone causes central nervous system depression. This is the correct explanation. Oxycodone, like other opioids, depresses the central nervous system, which can lead to respiratory depression by reducing the brainstem’s responsiveness to carbon dioxide levels in the blood.
Correct Answer is D
Explanation
A. Monitor the client’s thyroid function levels is not relevant to the administration of metformin, as metformin does not affect thyroid function.
B. Collect the client’s uric acid level is not necessary in this context, as metformin does not typically impact uric acid levels.
C. Obtain the client’s HDL level is not relevant to the administration of metformin, as metformin does not directly affect HDL levels.
D. Check the client’s glucose level is the most appropriate action, as metformin is an antidiabetic medication that lowers blood glucose levels. Monitoring the client’s glucose level will help assess the impact of the incorrect medication administration and guide further treatment.
