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.

Answer and Explanation

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 B

Explanation

Choice A rationale

Magnesium sulfate is primarily used for seizure prophylaxis in preeclampsia or eclampsia. It does not manage hemorrhagic conditions or uterine atony effectively, making it unsuitable for controlling postpartum hemorrhage.

Choice B rationale

Hemabate or Tranexamic Acid (TXA) addresses postpartum hemorrhage by promoting uterine contraction or inhibiting fibrinolysis. Hemabate is a prostaglandin, while TXA is an antifibrinolytic, both effective in hemorrhagic control.

Choice C rationale

Methergine (methylergonovine) induces uterine contraction to manage postpartum hemorrhage effectively but is contraindicated in hypertensive patients due to the risk of exacerbating hypertension or inducing stroke.

Choice D rationale

Nifedipine is a calcium channel blocker used to treat hypertensive disorders or preterm labor. It has no role in treating postpartum hemorrhage or enhancing uterine tone in such cases.

A. True. B. False.

Correct Answer is A

Explanation

Choice A rationale

Closed loop communication is essential in critical situations as it ensures that information is accurately sent, received, and confirmed, reducing errors by allowing team members to verify directives and actions.

Choice B rationale

Open-ended communication methods are prone to misinterpretations and delays in critical situations, making them unsuitable for ensuring precision and immediate understanding, as required in urgent medical scenarios.
