1. By what age does birth weight usually triple?

Correct answer: A

Rationale: The correct answer is A: 1 year. By the age of 1 year, a baby’s birth weight typically triples. This period allows for significant growth and development in infants. Choices B, C, and D are incorrect because birth weight does not usually triple by 1 month, 2 years, or 6 months of age, respectively.

2. What is the most effective method to prevent infection in the newborn?

Correct answer: B

Rationale: The most effective method to prevent infection in newborns is by practicing proper hand hygiene by staff and family. This is crucial as it helps reduce the transmission of infectious agents, protecting vulnerable newborns. Using disposable items may help, but proper hand hygiene is more effective. Administering prophylactic antibiotics without a specific indication can lead to antibiotic resistance and is not recommended. Isolating the newborn from others is not practical and may not be necessary if proper hand hygiene is maintained.

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. By which age should the nurse expect that an infant will be able to pull to a standing position?

Correct answer: C

Rationale: Pulling to a standing position typically occurs between 11 to 12 months, marking the progression towards walking.

5. At which age can most infants sit steadily unsupported?

Correct answer: C

Rationale: Most infants can sit steadily without support by 8 months, indicating advanced gross motor skill development.
