A nurse is caring for a client who has diabetes insipidus.
Which of the following findings should the nurse expect?

Choice A rationale:

Double vision is not a common side effect of quinolones. Quinolones are a type of antibiotic that are used to kill or inhibit the growth of bacteria. While they can have side effects, double vision is not typically one of them.

Choice B rationale:

Tendonitis and tendon rupture are known adverse effects of quinolones. These antibiotics can very rarely cause long-lasting, disabling, and potentially irreversible side effects, sometimes affecting multiple systems, organ classes, and senses. One of these side effects is damage to the tendons, which can manifest as tendonitis (inflammation of the tendon) or even tendon rupture. This is particularly a concern for people older than 60 years and for those with renal impairment or solid-organ transplants because they are at a higher risk of tendon injury.

Choice C rationale:

Neuralgia, or nerve pain, is not a common side effect of quinolones. While these antibiotics can affect the nervous system and cause side effects such as peripheral neuropathy and central nervous system effects, neuralgia is not typically reported.

Choice D rationale:

Hypotension, or low blood pressure, is not typically associated with the use of quinolones. These antibiotics can have various side effects, but a significant drop in blood pressure is not commonly reported.

Choice A rationale:

Erythromycin Erythromycin is a macrolide antibiotic that is often used as an alternative to penicillin. It is generally safe for use in patients with a penicillin allergy. It works by inhibiting bacterial protein synthesis and is effective against a wide range of bacteria.

Choice B rationale:

Amphotericin B Amphotericin B is an antifungal medication, not an antibiotic. It is used to treat serious, systemic fungal infections. It has no cross-reactivity with penicillin, so it would not be a concern for a patient with a penicillin allergy.

Choice C rationale:

Amoxicillin-clavulanate Amoxicillin-clavulanate is a type of penicillin antibiotic. Patients with a known penicillin allergy should avoid this medication, as they may have a cross-reactivity to it. This is why the nurse should verify this prescription with the provider.

Choice D rationale:

Gentamicin Gentamicin is an aminoglycoside antibiotic used to treat serious bacterial infections caused by gram-negative bacteria. It is not related to penicillin and would be safe for a patient with a penicillin allergy.
