A nurse is teaching a client who has a goiter appropriate food choices related to dietary needs. Which of the following client statements indicates an understanding of the teaching?

Choice A reason: Checking the client's deep tendon reflexes every 4 hr is a appropriate action for a nurse to take for a client who has hypomagnesemia. Hypomagnesemia is a low level of magnesium in the blood, which can cause neuromuscular excitability and hyperreflexia. The nurse should monitor the client's reflexes for signs of increased or decreased response, which can indicate worsening or improving hypomagnesemia.

Choice B reason: Encouraging the client to consume more fiber is not a relevant action for a nurse to take for a client who has hypomagnesemia. Fiber is beneficial for digestive health and blood glucose control, but it has no direct effect on magnesium levels. The nurse should encourage the client to consume foods that are rich in magnesium, such as green leafy vegetables, nuts, seeds, legumes, and whole grains.

Choice C reason: Restricting the client's fluid intake to 500 mL/day is not a safe or effective action for a nurse to take for a client who has hypomagnesemia. Fluid restriction can cause dehydration, electrolyte imbalance, and kidney damage, which can worsen hypomagnesemia. The nurse should maintain the client's fluid balance and monitor their urine output and specific gravity.

Choice D reason: Limiting sodium-containing foods on the client's meal tray is not a necessary action for a nurse to take for a client who has hypomagnesemia. Sodium is not directly related to magnesium levels, and limiting sodium intake can cause hyponatremia, which is a low level of sodium in the blood. The nurse should ensure that the client receives adequate sodium intake from their diet or supplements.

Choice A reason: Sipping fluids slowly throughout the day can help prevent dehydration and electrolyte imbalance, which can worsen nausea and vomiting. Fluids also help flush out the toxins from the chemotherapy and reduce the risk of kidney damage¹².

Choice B reason: Consuming foods that are served cold can help reduce the stimulation of the chemoreceptor trigger zone (CTZ), which is responsible for triggering nausea and vomiting. Cold foods also have less odor and taste, which can be unpleasant for some clients with CINV³⁴.

Choice C reason: Sitting up for 1 hr after eating meals can help prevent reflux and aspiration, which can cause more nausea and vomiting. Sitting up can also promote gastric emptying and digestion.

Choice D reason: Limiting the use of antiemetics until after the first emesis is not a recommended practice, as it can make nausea and vomiting more difficult to control. Antiemetics should be given before, during, and after chemotherapy, according to the emetogenic potential of the agents and the client's individual response.

Choice E reason: Eating foods low in carbohydrates is not a helpful strategy for CINV, as carbohydrates can provide energy and prevent hypoglycemia, which can also cause nausea and vomiting. Carbohydrates can also help settle the stomach and reduce acid production.
