A nurse is caring for a client who has moderate partial-thickness burns over 30% of their total body surface area. Which of the following actions should the nurse take?
Initiate a low-protein diet.
Provide a vitamin C supplement.
Administer a potassium-sparing diuretic.
Limit zinc intake.
The Correct Answer is B
A. Initiate a low-protein diet: A low-protein diet is inappropriate for burn clients, who require increased protein to support wound healing, tissue regeneration, and immune function. Protein needs are significantly elevated in clients with burns.
B. Provide a vitamin C supplement: Vitamin C supports collagen synthesis, promotes wound healing, and enhances immune function. Clients with partial-thickness burns benefit from supplementation to aid skin repair and recovery.
C. Administer a potassium-sparing diuretic: Diuretics are generally avoided in the early stages of burn care due to fluid shifts and risk of hypovolemia. Fluid resuscitation is prioritized to stabilize hemodynamics and maintain organ perfusion.
D. Limit zinc intake: Zinc plays a critical role in tissue healing and immune support. Limiting zinc would be counterproductive; burn clients often require additional zinc to meet increased metabolic demands.

Correct Answer is ["236"]
Explanation
Identify the calorie content per gram of each macronutrient.
Protein: 4 calories/gram
Fat: 9 calories/gram
Carbohydrates: 4 calories/gram
Calculate the calories from protein.
Calories from protein = 2 g × 4 calories/gram
= 8 calories.
Calculate the calories from fat.
Calories from fat = 12 g × 9 calories/gram
= 108 calories.
Calculate the calories from carbohydrates.
Calories from carbohydrates = 30 g × 4 calories/gram
= 120 calories.
Calculate the total calories in the cookie.
Total calories = Calories from protein + Calories from fat + Calories from carbohydrates
= 8 calories + 108 calories + 120 calories
= 236 calories.
Rounded to the nearest whole number: 236.
Correct Answer is B
Explanation
A. Apples: Apples are naturally low in phenylalanine, the amino acid that clients with phenylketonuria (PKU) cannot properly metabolize. Fruits like apples are generally safe and are encouraged in a low-phenylalanine diet because they help meet nutritional needs without contributing excess protein or phenylalanine.
B. Milk: Milk is high in protein and contains significant amounts of phenylalanine, making it unsuitable for individuals with PKU. Consuming milk can lead to elevated phenylalanine levels, which are harmful to the developing fetus and can cause cognitive impairments and developmental delays. Pregnant women with PKU must strictly avoid high-protein foods such as milk.
C. Carrots: Carrots are low in protein and phenylalanine, making them a safe and beneficial food choice for clients with PKU. They provide important nutrients like beta-carotene and fiber without compromising phenylalanine restrictions. Including vegetables like carrots supports balanced nutrition during pregnancy.
D. Coffee: Coffee itself contains minimal or no phenylalanine unless additives such as milk or cream are used. While caffeine intake should be moderated during pregnancy, plain coffee does not significantly impact phenylalanine levels and is not a food that must be avoided specifically because of PKU.
