A nurse is caring for a newborn who is placed in a neutral thermal environment.What is the desired outcome of this measure?
To minimize the patient’s oxygen needs.
To facilitate the conversion of glucose to lactic acid.
To decrease the absorption of surfactant from the alveoli.
To increase the patient’s ability to metabolize brown fat stores.
The Correct Answer is A
The correct answer is choice A: To minimize the patient’s oxygen needs.
A neutral thermal environment is an environment in which a neonate maintains a normal body temperature while minimizing energy expenditure and oxygen consumption. This is important for the wellbeing of neonates, especially those who are preterm or have respiratory insufficiency.
Choice B is wrong because the conversion of glucose to lactic acid is not a desired outcome of a neutral thermal environment. This conversion occurs when there is inadequate oxygen supply to the tissues, resulting in anaerobic metabolism and metabolic acidosis.
Choice C is wrong because the absorption of surfactant from the alveoli is not affected by a neutral thermal environment.
Surfactant is a substance that reduces surface tension and prevents alveolar collapse. It is produced by type II alveolar cells and secreted into the alveoli.
Choice D is wrong because the metabolism of brown fat stores is not a desired outcome of a neutral thermal environment.
Brown fat is a specialized tissue that generates heat by nonshivering thermogenesis in response to cold stress.
It is located in the nape of the neck, between the scapulae, and around the kidneys and adrenals. It increases the metabolic rate and oxygen consumption of neonates.

Correct Answer is C
Explanation
The correct answer is choice C. Have a suction catheter available for use at delivery.This is because meconium-stained amniotic fluid indicates that the fetus has passed meconium (first stool) before birth, which can be a sign of fetal distress or hypoxia.Meconium can block the airways and cause breathing problems for the newborn, so suctioning the mouth and nose (or the trachea if needed) is important to prevent meconium aspiration syndrome.
Choice A is wrong because taking the mother’s vital signs every 15 minutes is not a specific intervention for meconium-stained amniotic fluid.
Vital signs should be monitored regularly during labor regardless of the fluid color.
Choice B is wrong because sending a specimen of the fluid to the laboratory for analysis is not a priority action.The color and consistency of the fluid can be observed by the nurse and documented.
The laboratory analysis will not change the immediate management of the newborn.
Choice D is wrong because preparing a slide of the fluid for fern testing is not relevant for meconium-stained amniotic fluid.
Fern testing is used to confirm the rupture of membranes by detecting a fern-like pattern of amniotic fluid under a microscope.It is not useful for assessing the presence or severity of meconium-stained amniotic fluid.
