A nurse is caring for a client who is receiving continuous enteral nutrition and is experiencing diarrhea. Which of the following actions should the nurse take?

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: Increasing the caloric intake before pregnancy is not an appropriate dietary guideline, as it can lead to excessive weight gain and obesity, which can increase the risk of gestational diabetes, hypertension, and other complications. The nurse should advise the client to maintain a healthy weight and a balanced diet before and during pregnancy.

Choice B reason: Increasing the total intake of seafood to 20 ounces per week is not an appropriate dietary guideline, as it can expose the client to high levels of mercury, which can harm the developing fetus. The nurse should advise the client to limit the intake of seafood to 8 to 12 ounces per week, and avoid fish that are high in mercury, such as shark, swordfish, and king mackerel.

Choice C reason: Decreasing ascorbic acid in the diet is not an appropriate dietary guideline, as it can impair the immune system and the absorption of iron, which are both important for the health of the mother and the fetus. The nurse should advise the client to consume adequate amounts of ascorbic acid, which is found in citrus fruits, tomatoes, broccoli, and other foods.

Choice D reason: Increasing folic acid to 400 micrograms per day prior to getting pregnant is an appropriate dietary guideline, as it can prevent neural tube defects, such as spina bifida and anencephaly, in the fetus. The nurse should advise the client to take a daily prenatal vitamin that contains folic acid, and eat foods that are rich in folate, such as leafy greens, beans, and fortified cereals.
