A nurse is monitoring a client who has acute kidney injury (AKI). Which of the following laboratory findings should the nurse expect?

Choice A reason: Furosemide does not require a diet low in potassium; in fact, patients may need to increase their potassium intake due to its diuretic effect.

Choice B reason: Patients on furosemide should not limit fluid intake unless specifically instructed by their healthcare provider, as the medication is a diuretic.

Choice C reason: Furosemide is used to treat high blood pressure, so it would not cause an increase in blood pressure.

Choice D reason: Limiting sun exposure and wearing sunscreen is important as furosemide can make the skin more sensitive to sunlight.

The correct answer is Choice A

Choice A rationale: Headache and restlessness can be signs of a seizure or neurological disturbance, which phenytoin is used to treat. Phenytoin is an anticonvulsant medication that helps control seizures by stabilizing neuronal membranes and reducing excitability.

Choice B rationale: Decreased blood pressure and rapid pulse are not indications for phenytoin administration. These symptoms may suggest hypotension or cardiovascular issues, which require different interventions such as fluid resuscitation or vasopressors.

Choice C rationale: Muscle cramps and chest heaviness are not treated with phenytoin. These symptoms could indicate electrolyte imbalances or cardiac issues, which need specific treatments like electrolyte replacement or cardiac monitoring.

Choice D rationale: Pain and tingling at the access site are not indications for phenytoin administration. These symptoms may suggest local irritation or infection at the dialysis access site, requiring appropriate wound care or antibiotics.
