A nurse is providing teaching about formula feeding to the parents of an infant. Which of the following instructions should the nurse include?

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: Acute stress causes an increase in metabolism, as the body activates the sympathetic nervous system and releases hormones such as adrenaline and cortisol. These hormones increase the heart rate, blood pressure, and oxygen consumption, and mobilize glucose and fatty acids for energy. The nurse should explain to the clients that acute stress can have beneficial effects, such as enhancing alertness, memory, and performance, but it can also have harmful effects, such as impairing digestion, immunity, and growth.

Choice B reason: Stress causes a negative nitrogen balance in the body, not a positive one. Nitrogen balance is the difference between the amount of nitrogen ingested and the amount of nitrogen excreted. A positive nitrogen balance means that the body is retaining more nitrogen than it is losing, which indicates growth, healing, or pregnancy. A negative nitrogen balance means that the body is losing more nitrogen than it is retaining, which indicates malnutrition, illness, or injury. The nurse should inform the clients that stress can cause a negative nitrogen balance, as the body breaks down protein for energy and loses nitrogen through urine, sweat, and wounds.

Choice C reason: Protein requirements increase in times of stress, not decrease. Protein is essential for tissue repair, immune function, and hormone synthesis. The nurse should advise the clients that stress can increase the protein needs of the body, as the body loses protein through catabolism, inflammation, and infection. The nurse should recommend the clients to consume adequate amounts of high-quality protein, such as eggs, milk, cheese, meat, fish, poultry, soy, and nuts.

Choice D reason: Glucose is broken down more quickly during times of stress, not more slowly. Glucose is the main source of energy for the brain and the muscles. The nurse should educate the clients that stress can increase the glucose levels in the blood, as the body releases glucose from the liver and muscles to provide fuel for the stress response. The nurse should also warn the clients that chronic stress can lead to insulin resistance, diabetes, and cardiovascular disease.
