1. What is an important consideration when administering medications to a child with a history of chronic renal failure?

• A. Increased frequency of medication administration
• B. Adjustments in dosage due to altered drug metabolism
• C. Avoidance of all medications
• D. Use of only intravenous medications

Correct answer: B

Rationale: When administering medications to a child with chronic renal failure, it is crucial to consider adjustments in dosage due to altered drug metabolism. Children with chronic renal failure may have impaired drug excretion, leading to potential drug accumulation and toxicity. Increasing the frequency of medication administration (choice A) may not address the altered drug metabolism issue and could increase the risk of adverse effects. Avoiding all medications (choice C) is not practical or safe as some medications may be necessary for the child's health. Using only intravenous medications (choice D) is not always required and may not be the best route of administration for all medications needed.

2. What is the main function of proteins in the body?

• A. They provide structural components for the body.
• B. They assist in the absorption of vitamins.
• C. They help with the transport of nutrients in the blood.
• D. They help maintain fluid balance in the body.

Correct answer: A

Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).

3. Which nutrient is an example of a macronutrient?

• A. proteins
• B. minerals
• C. water-soluble vitamins
• D. fat-soluble vitamins

Correct answer: A

Rationale: Proteins are indeed macronutrients as they are required by the body in larger quantities for various functions such as growth, repair, and energy production. Choice B, minerals, are micronutrients needed in smaller amounts for various physiological processes. Choices C and D, water-soluble vitamins and fat-soluble vitamins, respectively, are also micronutrients that play essential roles in the body but are not classified as macronutrients.

4. Parents of a 6-month-old child, diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What should the nurse say?

• A. Are you sure your child has iron deficiency anemia?
• B. Maternal stores of iron are depleted at about 6 months.
• C. This anemia is caused by blood loss.
• D. The child may not have had it for a long time.

Correct answer: B

Rationale: The correct answer is B: 'Maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent around 6 months of age when the infant's iron stores, primarily received from the mother during pregnancy, are depleted. This timing coincides with the introduction of solid foods, which may lack sufficient iron. Choices A, C, and D are incorrect because they do not address the specific reason why iron deficiency anemia is typically diagnosed around 6 months of age.

5. How much energy is required to raise the temperature of one kilogram of water by 1°C?

• A. 10 calories
• B. 100 calories
• C. 1 kilocalorie
• D. 10 kilocalories

Correct answer: C

Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.
