A nurse is caring for a client immediately following a hemodialysis treatment. For which of the following manifestations will the nurse administer a PRN dose of phenytoin?

Headache, restlessness

Decreased blood pressure, rapid pulse

Muscle cramps, chest heaviness

Pain and tingling at the access site

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is ["50"]

Explanation

Step 1: The total amount of phenytoin required per dose is 250 mg.

Step 2: Each 5 mL of oral solution contains 25 mg of phenytoin.

Step 3: To find out how many mL are needed, we divide the total amount required by the amount in each 5 mL of oral solution. So, (250 mg ÷ 25 mg/5 mL).

Step 4: The result is 50 mL.

So, the nurse should administer 50 mL per dose. This is already a whole number, so no rounding is necessary.

A. "I should eat a diet low in potassium while taking this medication." B. "I should limit my fluid intake while taking this medication." C. "My blood pressure will increase while I am taking this medication." D. "I need to limit my sun exposure and wear sunscreen while on this medication."

Correct Answer is D

Explanation

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.
