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.

Explanation
Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur within seconds or minutes of exposure to an allergen, such as penicillin.
One of the symptoms of anaphylaxis is wheezing, which is caused by the constriction of the airways and a swollen tongue or throat.
Choice A is wrong because hypertonia (increased muscle tone) is not a known symptom of anaphylaxis.
Choice C is wrong because urinary retention (inability to completely empty the bladder) is not a known symptom of anaphylaxis.
Choice D is wrong because increased blood pressure is not a known symptom of anaphylaxis; in fact, anaphylaxis can cause a sudden drop in blood pressure.
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.
