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: 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.

Choice A reason: A low-protein diet is essential for clients who have PKU, as they cannot metabolize the amino acid phenylalanine. High levels of phenylalanine can cause intellectual disability and other neurological problems. A low-protein diet should be started before pregnancy and maintained throughout pregnancy to prevent fetal harm.

Choice B reason: Serum bilirubin is not related to PKU. It is a product of red blood cell breakdown and is elevated in conditions such as jaundice, liver disease, or hemolytic anemia. It does not need to be monitored routinely in clients who have PKU.

Choice C reason: Diet sodas are not recommended for clients who have PKU, as they often contain artificial sweeteners such as aspartame, which is a source of phenylalanine. Diet sodas should be avoided completely or consumed very sparingly by clients who have PKU.

Choice D reason: Breastfeeding will not prevent the baby from developing PKU, as PKU is a genetic disorder that is inherited from both parents. If both parents have PKU, the baby will have a 100% chance of having PKU. If one parent has PKU and the other is a carrier, the baby will have a 50% chance of having PKU. If one parent has PKU and the other is not a carrier, the baby will not have PKU but will be a carrier. Breastfeeding may provide some benefits for the baby, such as immunity and bonding, but it will not affect the baby's PKU status.
