Correct Answer is C

Explanation

The correct answer is choice c. Metallic taste Choice A rationale: Metronidazole is not associated with hearing loss as a common adverse effect. Hearing loss is more commonly linked to other medications, such as aminoglycosides. Choice B rationale: Alterations in touch, or peripheral neuropathy, can occur with metronidazole but are not the typical sense alteration reported by patients. Choice C rationale: Metallic taste is a well-documented adverse effect of metronidazole. Many patients report a metallic or unpleasant taste during therapy. Choice D rationale: Olfactory changes are not a commonly reported adverse effect of metronidazole. This is more often seen with certain other medications or conditions.

A. A recent history of diarrhea for 3 days. B. Serum creatinine 0.8 mg/dL. C. Severe allergy to amoxicillin. D. A history of phlebitis following an IV infusion of 0.9% sodium chloride with 10 mEq potassium chloride.

Correct Answer is C

Explanation

Cefoxitin is a cephalosporin antibiotic and can cause allergic reactions in people who are allergic to penicillin or other beta-lactam antibiotics like amoxicillin. Therefore, a severe allergy to amoxicillin is a contraindication for the client to receive cefoxitin, and the nurse should report this finding to the provider immediately.

A recent history of diarrhea for three days is not a contraindication for cefoxitin administration. However, the nurse should monitor the client for signs of diarrhea and report any worsening symptoms to the provider.

A serum creatinine level of 0.8 mg/dL is within the normal range and is not a contraindication for cefoxitin administration.

A history of phlebitis following an IV infusion of 0.9% sodium chloride with 10 mEq potassium chloride is not a contraindication for cefoxitin administration. However, the nurse should assess the client's veins carefully before administering the medication and choose a diﬀerent site or route for administration if necessary.
