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. Empty your bladder prior to the test.This is because a full bladder can interfere with the insertion of the needle and increase the risk of complications.Amniocentesis is a test that involves removing and testing a small sample of cells from amniotic fluid, the fluid that surrounds the baby in the womb.It is done to check for genetic or chromosomal conditions, such as Down’s syndrome, Edwards’ syndrome or Patau’s syndrome.
Choice A is wrong because there is no need to remain flat in bed for six hours after the test.You can resume your normal activities after a few hours of rest.
Choice B is wrong because vaginal bleeding is not a normal outcome of amniocentesis.If you experience any bleeding, leaking of fluid, fever or severe pain after the test, you should contact your doctor immediately.
Choice D is wrong because there is no restriction on eating before the test.You can have your normal meals and drinks before amniocentesis.
