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.

It may also make the patient feel uncomfortable or judged.
Choice B is wrong because the type of contraceptive that the patient’s friends are using is not a reliable source of information.
Different methods may have different advantages and disadvantages for different people.
The nurse should provide evidence-based information and guidance on various options.
Choice D is wrong because the method of contraception that the patient believes will provide protection from sexually transmitted diseases may not be accurate or effective.
Correct Answer is D
Explanation
The correct answer is choice D. Insufficient relaxation of the uterus between contractions.This is also known astachysystoleorhyperstimulation, which can cause fetal distress and uterine rupture.Oxytocin is a hormone that stimulates uterine contractions, but it can also cause them to be too strong or too frequent if given in high doses or for too long.
Choice A is wrong because oxytocin does not decrease body temperature.
Choice B is wrong because oxytocin does not cause maternal cardiac arrhythmias.
Choice C is wrong because oxytocin does not cause urinary retention.
