A nurse is preparing to administer mannitol 0.2 g/kg IV bolus over 5 min as a test dose to a client who has severe oliguria. The client weighs 198 lb. What is the amount in grams the nurse should administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

- A. This choice is incorrect because verapamil and TPN do not have a significant food and medication interaction. Verapamil is a calcium channel blocker that can lower blood pressure and heart rate, while TPN is a form of intravenous nutrition that provides calories, electrolytes, vitamins, and minerals. The nurse should monitor the client's vital signs and blood glucose levels, but there is no need to intervene to prevent an interaction.

- B. This choice is incorrect because phenytoin and milkshakes do not have a significant food and medication interaction. Phenytoin is an anticonvulsant that can decrease the absorption of some vitamins, such as folic acid and vitamin D, but milkshakes are not a major source of these nutrients. The nurse should encourage the client to eat a balanced diet and take supplements as prescribed, but there is no need to intervene to prevent an interaction.

- C. This choice is incorrect because potassium-rich foods and furosemide do not have a significant food and medication interaction. Furosemide is a loop diuretic that can cause hypokalemia, or low potassium levels, but potassium-rich foods can help prevent this complication. The nurse should monitor the client's electrolyte levels and fluid balance, but there is no need to intervene to prevent an interaction.

- D. This choice is correct because MAOIs and cheeseburgers have a significant food and medication interaction. MAOIs are antidepressants that can cause hypertensive crisis, or dangerously high blood pressure, if the client consumes foods that contain tyramine, such as aged cheeses, cured meats, fermented foods, and beer. The nurse should intervene to prevent the client from eating a cheeseburger and educate the client about avoiding tyramine-containing foods while taking MAOIs.

Choice A rationale:

Fidelity refers to the principle of being loyal, faithful, and keeping promises. It does not specifically relate to providing accurate information about treatment effects. In this scenario, the nurse is discussing the potential adverse effects of a treatment, which falls under the domain of providing accurate and truthful information to the client.

Choice B rationale:

Beneficence is the ethical principle of doing good and promoting the well-being of the patient. While educating the client about potential adverse effects is a form of beneficence, the specific principle demonstrated in this scenario is veracity, which is the duty to tell the truth. The nurse is being truthful about the potential side effect (lightheadedness) while clarifying that it should not affect memory.

Choice C rationale:

Veracity is the ethical principle of truth-telling. In this scenario, the nurse is demonstrating veracity by providing honest and accurate information to the client about the potential adverse effects of transcranial magnetic stimulation. By being truthful, the nurse upholds the ethical principle of veracity.

Choice D rationale:

Autonomy refers to the principle of respecting the patient's right to make decisions about their own healthcare. While respecting autonomy is important, the nurse's action in this scenario specifically pertains to providing accurate information (veracity) rather than solely focusing on the client's decision-making autonomy.
