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 B
Explanation
This is because hypotension (low blood pressure) can be a sign of anaphylaxis, which is a severe allergic reaction that can occur with ceftriaxone.

Choice A is wrong because polyuria (increased urination) is not a common sign of an allergic reaction to ceftriaxone.
Choice C is wrong because nausea can be a side effect of ceftriaxone but is not specific to an allergic reaction.
Choice D is wrong because bradycardia (slow heart rate) is not a common sign of an allergic reaction to ceftriaxone.
Correct Answer is D
Explanation
Combining furosemide with certain aminoglycoside antibiotics like amikacin may increase the risk of hearing loss.
The nurse should monitor this client for hearing loss related to a medication interaction.
Choice A is wrong because there is no known interaction between losartan and atorvastatin that can cause hearing loss.
Choice B is wrong because there is no known interaction between propranolol and raloxifene that can cause hearing loss.
Choice C is wrong because there is no known interaction between digoxin and levothyroxine that can cause hearing loss.
