A nurse is preparing to administer prescribed intravenous potassium replacement supplements to a client who has a potassium level of 2.5 mEq/L (normal range: 3.5 to 5 mEq/L). Which of the following actions should the nurse plan to include? (Select all that apply.)

Choice A reason: The erythrocyte sedimentation rate (ESR) is not directly affected by epoetin alfa therapy, which is used to treat anemia.

Choice B reason: Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production, which would be reflected in an increased hematocrit level.

Choice C reason: The platelet count is not directly affected by epoetin alfa therapy.

Choice D reason: The leukocyte count is not directly affected by epoetin alfa therapy.

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.
