1. Why is the specific gravity for infants lower than for older children?

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. A newborn diagnosed with an omphalocele defect is admitted to the intensive care nursery. Which nursing action is appropriate based on the current data?

Correct answer: A

Rationale: Placing the newborn on a radiant warmer is appropriate as it helps maintain the body temperature and prevent hypothermia in a newborn with an omphalocele defect. This is crucial for the infant's well-being and supports their physiological stability.

3. In caring for an adolescent with severe abdominal pain due to appendicitis, where should the nurse identify as McBurney's point?

Correct answer: A

Rationale: McBurney's point is located in the right lower quadrant of the abdomen, specifically between the umbilicus and the anterior iliac crest. This point is significant in diagnosing appendicitis, as tenderness at McBurney's point is a classic sign of appendicitis and indicates inflammation near the appendix. Therefore, the correct answer is the 'Right lower quadrant.' Choices B, C, and D are incorrect because McBurney's point is not located in the left lower quadrant, right upper quadrant, or left upper quadrant of the abdomen.

4. Which model of practice emphasizes the child's subjective experience of their abilities?

Correct answer: B

Rationale: The Model of Human Occupation (MOHO) emphasizes the child's subjective experience of their abilities, focusing on their motivation, roles, habits, and routines. It considers how these factors influence their occupational performance. MOHO helps occupational therapists understand how a child's perceptions of their abilities impact their engagement in meaningful activities and occupations.

5. The nurse is preparing to administer a daily dose of digoxin. What is the priority nursing intervention?

Correct answer: A

Rationale: Before giving digoxin, the nurse will assess the HR and rhythm. The dosage will be held and the prescriber notified if the HR is below 60 bpm or if the cardiac rhythm has changes. Digoxin can cause bradycardia and electrical changes in the heart.
