Correct Answer: C

Rationale: The correct answer is C. Eating foods high in fiber increases stool bulk and promotes easier elimination, thus preventing constipation. Choices A, B, and D are incorrect. Drinking water is important, but the emphasis should be on high-fiber foods. Mineral oil is not a recommended first-line treatment for constipation, and skipping meals can disrupt regular bowel movements, potentially leading to constipation.

Correct Answer: A

Rationale: The correct answer is A. Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function. Avocado (choice B) is a good source of healthy fats but not high in vitamin A. Green beans (choice C) are nutritious but not a significant source of vitamin A. Apples (choice D) are low in vitamin A compared to sweet potatoes.

Correct Answer: A

Rationale: The correct answer is A: Eggs. Eggs are one of the most common food allergens in toddlers and should be introduced carefully. Milk (choice B) is also a common allergen but is typically introduced earlier in a child's diet. Bananas (choice C) and citrus fruits (choice D) are less likely to cause allergic reactions compared to eggs.

Correct Answer: A

Rationale: An elevated hematocrit level (Hct 53%) indicates hemoconcentration, a sign of fluid volume deficit. Hct measures the percentage of red blood cells in the blood and increases when there is a decrease in plasma volume, as seen in fluid volume deficit. Choices B, C, and D do not directly relate to fluid volume status. Potassium and sodium levels are more indicative of electrolyte imbalances, while HbA1c reflects average blood sugar levels over the past 2-3 months and is not specific to fluid volume status.

Correct Answer: C

Rationale: The correct recommendation for a client with chronic kidney disease is to limit protein intake. Excessive protein consumption can strain the kidneys as they work to eliminate waste products from protein metabolism. This can worsen kidney function in individuals with chronic kidney disease. Therefore, limiting protein intake is crucial in managing this condition. Choices A, B, and D are incorrect. Increasing phosphorus intake can be harmful in kidney disease as it can lead to mineral imbalances. Limiting calcium intake is not typically necessary unless the client has specific complications. Increasing potassium intake may also be inappropriate as potassium levels can be affected in kidney disease.
