A nurse is reinforcing teaching with a client who reports motion sickness about using an herbal supplement. The nurse should identify that the client can use which of the following herbal supplements to help control nausea?

A. Ibuprofen:

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve pain and reduce inflammation. There are no significant interactions reported between erythromycin and ibuprofen.

B. Lasix (Furosemide):

Lasix is a diuretic medication used to treat fluid retention (edema) and high blood pressure. There are no significant interactions reported between erythromycin and furosemide.

C. Lovastatin:

Lovastatin is a statin medication used to lower cholesterol levels. Erythromycin can increase the levels of lovastatin in the blood by inhibiting its metabolism through the CYP3A4 enzyme. This can lead to an increased risk of statin-related side effects, including muscle pain and weakness, and in rare cases, rhabdomyolysis.

D. Lisinopril:

Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat high blood pressure and heart failure. There are no significant interactions reported between erythromycin and lisinopril.

A. She only has one functioning kidney:

This choice is the most significant consideration when prescribing vancomycin to Mrs. Oza. Vancomycin is primarily eliminated from the body through the kidneys. Individuals with reduced kidney function, such as Mrs. Oza with only one functioning kidney, have a higher risk of vancomycin-associated nephrotoxicity (kidney damage). Therefore, her renal status is crucial information for determining the appropriate dosage of vancomycin and monitoring for any signs of kidney impairment during treatment.

B. She remains outdoors for long periods of time:

While spending time outdoors for long periods may have implications for Mrs. Oza's overall health, it is not directly relevant to the prescription of vancomycin. This information may be important for considering sun exposure, hydration, and other factors related to her arthritis and general well-being, but it does not specifically impact the pharmacokinetics or pharmacodynamics of vancomycin.

C. She has hypertension:

Mrs. Oza's hypertension is a relevant medical condition to consider in her overall health management. However, hypertension alone does not directly affect the prescription of vancomycin. Hypertension may influence the choice of antihypertensive medications or other aspects of her medical care, but it does not have a direct impact on the renal clearance or potential nephrotoxicity of vancomycin.

D. She enjoys an alcoholic beverage twice a week:

While alcohol consumption can interact with certain medications and impact overall health, it is not the most significant consideration when prescribing vancomycin to Mrs. Oza. Moderate alcohol consumption is unlikely to directly affect the pharmacokinetics or pharmacodynamics of vancomycin. However, excessive alcohol intake may contribute to liver dysfunction, which could indirectly influence drug metabolism. Nonetheless, in Mrs. Oza's case, her reduced renal function is a more critical factor to consider when prescribing vancomycin.
