1. How is family systems theory best described?

Correct answer: D

Rationale: Family systems theory views the family as a whole, where changes in one member affect the entire system, and changes can occur at any point within the system.

2. A parent brings their 4-year-old child for a check-up. Which finding would concern the nurse?

Correct answer: B

Rationale: A resting pulse rate of 120 is elevated for a 4-year-old and may indicate an underlying issue that needs further investigation. An ectomorphic body type is a body shape and not typically a cause for concern. Weight gain within normal limits and no significant change in appetite are generally positive findings in a growing child.

3. The nurse suspects fluid overload in an infant receiving intravenous fluids. What clinical manifestation is suggestive of water intoxication?

Correct answer: C

Rationale: Water intoxication can lead to cerebral edema, causing neurological symptoms such as irritability and seizures. Oliguria, weight loss, and muscle weakness are not typical signs of water intoxication.

4. Parents of a newborn with ambiguous genitalia want to know how long they will have to wait to know whether they have a boy or a girl. The nurse answers the parents based on what knowledge?

Correct answer: D

Rationale: Gender assignment in cases of ambiguous genitalia is a complex process that requires a multidisciplinary approach, including genetic, endocrinological, and psychological evaluations. The decision should be made collaboratively with the parents.

5. Why are neonates predisposed to problems with thermoregulation?

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.
