Correct Answer is D
Explanation
Choice A rationale
A newborn typically begins to void within 24 hours after birth, so not voiding within this time frame is not immediately concerning.
Choice B rationale
Acrocyanosis, or bluish discoloration of the hands and feet, is common in newborns, especially within the first few hours after birth. It is a normal finding and does not require immediate intervention.
Choice C rationale
A temperature of 37.5°C (99.5°F) is within the normal range for a newborn. Therefore, this does not require immediate attention.
Choice D rationale
Newborns typically pass meconium, the first stool, within 24 to 48 hours after birth. If a newborn has not passed meconium within 24 hours, it could indicate a problem such as meconium ileus, a complication of cystic fibrosis, or other conditions that might obstruct the bowel. This situation requires immediate attention and intervention.
