The parents of a 30-week preterm infant ask the nurse why the baby can get cold so easily. The nurse explains:
Preterm neonates shiver to retain heat.
Preterm neonates lie in a fetal position.
Preterm neonates’ blood vessels are deeper under the surface of their skin.
Preterm neonates have minimal body fat to retain body heat.
The Correct Answer is D
Choice A rationale
Preterm neonates lack developed mechanisms to shiver for thermogenesis, relying instead on non-shivering thermogenesis primarily through brown fat metabolism, which is underdeveloped in preterm infants.
Choice B rationale
The fetal position does not significantly affect heat retention in preterm neonates, as their thermoregulatory mechanisms depend on adequate fat stores and skin coverage.
Choice C rationale
Blood vessels in preterm neonates are closer to the skin's surface, increasing heat loss due to greater exposure and lack of insulating subcutaneous fat.
Choice D rationale
Preterm neonates have minimal body fat, impeding insulation and heat retention, leading to rapid heat loss, necessitating external warming measures like incubators or radiant warmers.

Correct Answer is D
Explanation
Choice A rationale
Engorgement is caused by milk overproduction or improper drainage rather than cracked nipples. While related to breastfeeding issues, it is not directly linked to cracked or bleeding nipples.
Choice B rationale
Mastitis is an infection of breast tissue that occurs due to milk stasis or blocked ducts. Cracked nipples increase infection risks, but mastitis is secondary to these infections.
Choice C rationale
Decrease in milk production is influenced by hormonal imbalances or poor latch rather than by cracked or bleeding nipples. It does not directly result from nipple trauma.
Choice D rationale
Cracked nipples create an entry point for bacteria, significantly increasing infection risks such as cellulitis or abscess formation. Proper hygiene and wound care are essential to reduce complications.
Correct Answer is A
Explanation
Choice A rationale
Postpartum depression with psychotic features may lead to suicidal ideation or infanticidal tendencies due to delusions or hallucinations. Ensuring safety is critical to prevent harm to both mother and infant.
Choice B rationale
Anger outbursts, though concerning, do not pose immediate threats like harm to self or infant. Addressing this behavior is secondary to prioritizing safety in severe postpartum psychosis cases.
Choice C rationale
Neglecting hygiene reflects depressive symptoms but does not indicate psychosis severity or imminent danger. Primary focus remains on managing safety risks to the mother and infant.
Choice D rationale
Losing trust in her husband is relevant to interpersonal stress but does not constitute a primary care concern. The immediate threat of harm takes precedence over marital dynamics.
