Correct Answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.

Correct Answer: D

Rationale: Monitoring growth and development is crucial for children with congenital heart disease to ensure they are meeting developmental milestones and managing the disease effectively. This helps healthcare providers assess the child's overall health, detect any potential issues early, and adjust treatment plans accordingly. Restricting physical activity may not be necessary for all children with congenital heart disease and should be determined by their healthcare team based on individual needs. Increasing fluid intake and administering high doses of vitamins may not be directly related to managing congenital heart disease and should be guided by specific recommendations from healthcare providers.

Correct Answer: D

Rationale: The correct answer is D: Fiber. Macronutrients are nutrients required by the body in larger amounts, and they include carbohydrates, proteins, and fats. Fiber is a type of carbohydrate that falls under this category. Vitamin C (choice A) is a water-soluble vitamin, Iron (choice B) is a mineral, and Calcium (choice C) is also a mineral, not a macronutrient. Therefore, Fiber is the only macronutrient listed in the choices.

Correct Answer: B

Rationale: Monitoring for signs of infection is crucial when caring for a child with an indwelling urinary catheter. This is because catheter-associated urinary tract infections are common in such cases. Increasing fluid intake can be beneficial, but monitoring for infection takes precedence as it is crucial to prevent complications. Restricting mobility is not a key aspect of care for a child with an indwelling urinary catheter unless specifically advised by a healthcare provider. Administering daily antibiotics without proper assessment and indication can lead to antibiotic resistance and is not a standard practice in caring for a child with an indwelling urinary catheter.

Correct Answer: A

Rationale: The correct answer is A: Use of steroid creams. Steroid creams are commonly used in the management of eczema to reduce inflammation and itching, thus improving the skin condition and comfort of the child. Choice B, frequent antibiotic therapy, is incorrect as antibiotics are not typically used to treat eczema unless there is a secondary bacterial infection. Choice C, a high-protein diet, is not a specific recommendation for eczema treatment. Choice D, daily baths in hot water, is not recommended for eczema care as hot water can exacerbate the condition by drying out the skin.
