A nurse is caring for a client who has a ventricular dysrhythmia and a new prescription for amiodarone.
Which of the following interventions should the nurse include in the client's plan of care?

Choice A rationale

Constipation is not a commonly associated adverse effect of ciprofloxacin. Fluoroquinolones primarily impact gastrointestinal motility through alterations in gut flora and direct irritation, often leading to diarrhea or abdominal discomfort rather than constipation. The drug's mechanism does not typically promote slowed bowel movements or decreased peristalsis.

Choice B rationale

Weight gain is not a typical adverse effect of ciprofloxacin. Fluoroquinolones do not directly influence metabolic pathways or fluid retention in a manner that would lead to increased body mass. Adverse effects are usually related to gastrointestinal disturbances, neurological effects, or musculoskeletal issues.

Choice C rationale

Phototoxicity is a significant adverse effect of ciprofloxacin, a fluoroquinolone antibiotic. This occurs due to the drug's ability to absorb ultraviolet radiation, leading to a photochemical reaction that damages skin cells. This damage can manifest as severe sunburn, blistering, or rash upon exposure to sunlight.

Choice D rationale

Bradycardia is not a recognized adverse effect of ciprofloxacin. While some antibiotics can rarely affect cardiac conduction, ciprofloxacin's primary cardiovascular concerns relate more to QT prolongation and potential arrhythmias, not typically a decrease in heart rate. Its mechanism does not directly depress sinoatrial node function.

Choice A rationale

Gingival hyperplasia is an overgrowth of gum tissue, often associated with certain medications like phenytoin or cyclosporine. It is caused by an increase in the number of fibroblasts and collagen deposition in the gingiva. Haloperidol, an antipsychotic, primarily affects dopamine receptors in the brain and does not cause gingival hyperplasia.

Choice B rationale

Haloperidol is a first-generation antipsychotic that blocks D2 dopamine receptors in the brain. This blockade, particularly in the nigrostriatal pathway, can lead to extrapyramidal symptoms (EPS) such as acute dystonia, parkinsonism (including muscle rigidity, bradykinesia, and tremor), and akathisia. Muscle rigidity is a common manifestation of drug-induced parkinsonism.

Choice C rationale

Polyuria is the excessive production of urine, often a symptom of diabetes mellitus or insipidus. It results from impaired water reabsorption in the kidneys. While some medications can affect fluid balance, haloperidol's primary pharmacological action on dopamine receptors does not directly induce polyuria as a typical adverse effect.

Choice D rationale

Bruising, or ecchymosis, results from bleeding under the skin, often due to trauma or coagulation disorders. It is caused by extravasation of blood from capillaries into surrounding tissues. Haloperidol does not affect coagulation factors or platelet function and is not associated with increased bruising as a direct adverse effect.
