Correct Answer: C

Rationale: In extremely low-birth-weight (ELBW) infants, a thorough systemic physical assessment is crucial to detect subtle changes that may indicate an underlying problem. These infants are highly vulnerable and may show signs of stress through changes in feeding behavior, activity, color, oxygen saturation, or vital signs. Monitoring weight in ELBW infants primarily reflects genitourinary function rather than fluid retention. Difficulties in maternal-child attachment are important but are usually assessed during parental visits and are not the primary focus of a systemic physical assessment. Changes in the Apgar score are used immediately after birth to assess the transition to extrauterine life and are not as relevant in the following 24 hours to detect ongoing subtle issues.

Correct Answer: A

Rationale: Engaging the infant in a familiar game like peek-a-boo can help reduce fear and build rapport before starting the assessment.

Correct Answer: D

Rationale: Oral sucrose and nonnutritive sucking are effective nonpharmacologic interventions for reducing procedural pain in neonates.

Correct Answer: D

Rationale: Accidents, such as motor vehicle accidents, drowning, and falls, are the primary cause of death in children over 1 year of age. While congenital anomalies can be a significant cause of mortality in infants, they are less common in older children. Homicide and suicide are serious issues but are not as prevalent as accidents in causing death among children over 1 year of age.

Correct Answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.
