A nurse is caring for a client who has acute kidney injury and has been prescribed total parenteral nutrition (TPN). When educating the client on the use of TPN, which of the following information should the nurse include?
The TPN is needed to bypass your gastrointestinal tract.
The TPN will have higher levels of vitamins than the recommended daily intake.
The TPN will ensure that your glucose level stays within the expected range.
The TPN will be higher in fats and protein, but lower in carbohydrates.
The Correct Answer is A
Choice A reason: TPN is a form of nutrition that is delivered directly into the bloodstream through a central venous catheter. It is used for clients who have impaired or nonfunctional gastrointestinal tracts, such as those with acute kidney injury, bowel obstruction, or short bowel syndrome.
Choice B reason: The TPN does not necessarily have higher levels of vitamins than the recommended daily intake. The TPN is individually tailored to meet the client's nutritional needs, which may vary depending on their condition, weight, and laboratory values.
Choice C reason: The TPN does not ensure that the client's glucose level stays within the expected range. In fact, TPN can cause hyperglycemia due to the high concentration of dextrose in the solution. The client's blood glucose level should be monitored frequently and insulin should be administered as prescribed to prevent complications.
Choice D reason: The TPN is not higher in fats and protein, but lower in carbohydrates. The TPN contains a balanced mixture of macronutrients, including carbohydrates, proteins, and lipids, as well as micronutrients, such as electrolytes, vitamins, and minerals. The ratio of these components may vary depending on the client's nutritional needs and goals.

Correct Answer is A
Explanation
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.
Correct Answer is C
Explanation
Choice A reason: Calcium is not a dietary supplement that can help with wound healing, although it is important for bone health and muscle contraction. Calcium deficiency can cause osteoporosis, muscle cramps, and abnormal heart rhythms, but it does not affect wound healing.
Choice B reason: Potassium is not a dietary supplement that can help with wound healing, although it is essential for nerve and muscle function and fluid balance. Potassium deficiency can cause weakness, fatigue, arrhythmias, and muscle cramps, but it does not affect wound healing.
Choice C reason: Vitamin C is a dietary supplement that can help with wound healing, as it is involved in collagen synthesis, tissue repair, and immune response. Vitamin C deficiency can cause scurvy, which is characterized by bleeding gums, poor wound healing, and anemia.
Choice D reason: Vitamin D is not a dietary supplement that can help with wound healing, although it is necessary for calcium absorption, bone health, and immune function. Vitamin D deficiency can cause rickets, osteomalacia, and increased risk of infections, but it does not affect wound healing.
