1. Which parameter correlates best with measurements of total muscle mass?

Correct answer: D

Rationale: Upper arm circumference correlates best with total muscle mass because it includes both muscle and fat components, making it a reliable indicator of muscle mass.

2. What nursing consideration is most important when caring for a child with end-stage renal disease (ESRD)?

Correct answer: D

Rationale: ESRD places significant stress on both the child and the family due to the ongoing need for dialysis, medications, and lifestyle restrictions, making it important for healthcare providers to offer extensive support and resources to manage these challenges.

3. The parents of an 8-month-old infant voice concern to the nurse that their infant is not developing motor skills as the infant should. What question would be appropriate for the nurse to ask in determining if their fears are warranted?

Correct answer: A

Rationale: The correct answer is A. By 8 months, an infant should be able to transfer objects between hands, which is an important motor skill milestone. This action shows coordination and developing fine motor skills. Choices B, C, and D involve more advanced motor skills that are typically not expected at 8 months of age. Drinking from a cup, holding a pencil to scribble, and engaging in purposeful play with toys are skills that develop later in infancy.

4. While making rounds, the nurse observes the following client behaviors. Which child should the nurse further evaluate for postoperative pain?

Correct answer: D

Rationale: The correct answer is D because screaming and thrashing his arms and legs are indicative behaviors of discomfort or pain in young children. The child's actions suggest a higher likelihood of experiencing postoperative pain and necessitate further evaluation. Choices A, B, and C do not exhibit overt signs of distress or discomfort associated with pain, making them less likely candidates for postoperative pain assessment.

5. What is a classic sign of congenital hypothyroidism in newborns?

Correct answer: C

Rationale: Prolonged jaundice is a classic sign of congenital hypothyroidism in newborns. In congenital hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to symptoms like jaundice, poor feeding, constipation, and lethargy. While jaundice itself is a common condition in newborns, the term 'prolonged jaundice' specifically points towards the underlying thyroid issue. Hypothermia and excessive crying are not typically associated with congenital hypothyroidism.
