A nurse is teaching a newly licensed nurse about advance directives.
Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

Choice A rationale:

Repositioning the NG tube is not the appropriate action for hyperosmolar dehydration. This condition occurs due to an excessive concentration of solutes in the body, leading to a decrease in intracellular water. Repositioning the tube would not address the hyperosmolarity issue.

Choice B rationale:

Increasing the rate of formula delivery may exacerbate the problem by introducing more concentrated formula into the client's system, worsening hyperosmolarity. This choice can lead to further dehydration and electrolyte imbalances.

Choice C rationale:

Adding water to the formula is the correct action in this scenario. Hyperosmolar dehydration requires dilution of the concentrated formula to reduce the osmolarity. By adding water to the formula, the nurse can decrease the concentration of solutes, helping to rehydrate the client effectively.

Choice D rationale:

Switching to a lactose-free formula is not the appropriate intervention for hyperosmolar dehydration. The issue lies in the concentration of the formula, not in its lactose content. Adding water is the more suitable and direct approach to address the problem.

- 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.
