A nurse is reviewing the medical history of a client prior to medication administration and notes a history of an anaphylactic reaction to penicillin.
The nurse should identify that which of the following medications is contraindicated for this client?
Vancomycin.
Clarithromycin.
Metronidazole.
Ceftriaxone.
The Correct Answer is D
Ceftriaxone is contraindicated for this client because it is a cephalosporin antibiotic, which has a similar structure to penicillin and can cause cross-reactivity in individuals with a penicillin allergy.
Choice A is wrong because Vancomycin is not a beta-lactam antibiotic and does not have cross-reactivity with penicillin.
Choice B is wrong because Clarithromycin is a macrolide antibiotic and does not have cross-reactivity with penicillin.
Choice C is wrong because Metronidazole is a nitroimidazole antibiotic and does not have cross-reactivity with penicillin.

Correct Answer is A
Explanation
Spironolactone is a potassium-sparing diuretic that can increase potassium levels in the blood.
It is important for clients taking spironolactone to limit their intake of potassium-rich foods to prevent hyperkalemia (high potassium levels).
Choice B is wrong because “I will take the medication on an empty stomach,” is not the correct answer because spironolactone can be taken with or without food.
Choice C is wrong because “I will use salt substitutes in place of table salt,” is not the correct answer because many salt substitutes contain potassium and can increase the risk of hyperkalemia.
Choice D is wrong because “I will double up on my medication if I miss a dose,” is not the correct answer because it is not recommended to double up on medication if a dose is missed.
