A nurse is collecting data from a client who takes several daily medications and states that he wants to ask the provider for a prescription for sildenafil. The nurse knows that sildenafil is contraindicated due to an interaction with which of the following client's medications?

Cefuroxime

Metformin

Isosorbide

Naproxen

Answer and Explanation

The Correct Answer is C

A.   There's no documented interaction between cefuroxime and sildenafil. Cefuroxime is an antibiotic, and there are no known significant interactions with sildenafil.
B.   There's no documented interaction between metformin and sildenafil. Metformin, an antidiabetic medication, does not interact significantly with sildenafil.
C.   Both sildenafil and isosorbide are vasodilators, and concomitant use can result in severe hypotension due to additive effects on blood pressure lowering. Therefore, their combination is contraindicated.

D.   Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), does not have a significant interaction with sildenafil. They can be safely used together in most cases, although caution may be needed in individuals with cardiovascular risk factors.

Correct Answer is A

Explanation

A. Lithium can cause hypothyroidism and goiter as adverse effects. Therefore, monitoring of thyroid function and physical examination for thyroid enlargement is necessary during lithium therapy.
B. Constipation is not a typical adverse effect of lithium carbonate. It's more commonly associated with side effects such as nausea, diarrhea, or polyuria.

C. Hyporeflexia is not commonly associated with lithium carbonate use. Lithium more commonly affects the central nervous system, leading to symptoms such as tremors, confusion, and seizures in cases of toxicity.
D. Lithium is more commonly associated with the opposite effect, lowering blood pressure rather than elevating it. It's known to have effects on sodium transport in renal tubules, leading to increased water retention and possibly hypotension.

A. "I'll need to report weight loss or gain to my provider while taking this medication." B. "I can stop taking this medication if I'm feeling better after the first month." C. “I should avoid eating cheese while taking this medication." D. "I'll take my second dose of this medicine at bedtime."

Correct Answer is A

Explanation

A. Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), can cause changes in weight.

Reporting weight changes to the healthcare provider is important for monitoring and managing potential side effects.

B. Fluoxetine and other antidepressants should not be stopped abruptly without consulting a healthcare provider, even if the client starts feeling better. Abrupt discontinuation can lead to withdrawal symptoms and worsening of depression.
C. Fluoxetine does not typically interact with cheese or tyramine-containing foods. This statement reflects a misunderstanding of the medication's dietary restrictions.
D. Fluoxetine is usually taken once daily in the morning due to its potential to cause insomnia as a side effect. Taking it at bedtime may exacerbate sleep disturbances.
