Your patient is allergic to penicillin. He may also have a cross-allergy to which class of antibiotics?

Aminoglycosides

Sulfonamides

Macrolides

Cephalosporins

Answer and Explanation

The Correct Answer is D

A. Aminoglycosides: Aminoglycosides are a separate class of antibiotics with a different chemical structure than penicillins. There is no known cross-allergy between penicillins and aminoglycosides.
B. Sulfonamides: Sulfonamides are also a different class of antibiotics, and there is no significant cross-allergy risk with penicillins. However, individuals with allergies to sulfonamide medications may have a higher risk of allergic reactions to other sulfonamide-containing drugs, but this is unrelated to penicillin allergy.
C. Macrolides: Macrolides, such as erythromycin and azithromycin, have a different chemical structure than penicillins, and cross-allergy between penicillins and macrolides is rare. They are considered alternative antibiotic options for patients with penicillin allergies.
D. Cephalosporins: Cephalosporins are a class of antibiotics structurally and chemically related to penicillins. There is a risk of cross-allergy between penicillins and cephalosporins due to their similar beta-lactam ring structure. However, the extent of cross-reactivity varies among different cephalosporins and individual patient sensitivities. It's essential to assess the severity of the penicillin allergy and consider alternative antibiotics if cross-allergy is a concern.

A. She enjoys an alcoholic beverage twice a week B. She remains outdoors for long periods of time C. She only has one functioning kidney D. She has hypertension

Correct Answer is C

Explanation

A. She enjoys an alcoholic beverage twice a week: While alcohol can affect kidney function, occasional moderate intake might not be a major concern for vancomycin.
B. She remains outdoors for long periods of time: Sun exposure is not a major concern for vancomycin.
C. She only has one functioning kidney: This is the most significant factor. Vancomycin is primarily excreted by the kidneys. With only one functioning kidney, there's an increased risk of drug accumulation and potential toxicity if the dose is not adjusted for renal function.
D. She has hypertension: Hypertension itself might not significantly affect vancomycin use, although some medications for hypertension can interact with other drugs.
