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 B
Explanation
The correct answer is choice B. The patient’s uterine contraction pattern is enhanced.Prostaglandin E2 gel is used to induce labor by ripening and dilating the cervix and stimulating uterine contractions.The effectiveness of the gel can be measured by the frequency, duration and intensity of the contractions.
A stronger and more regular contraction pattern indicates that the gel is working and labor is progressing.
Choice A is wrong because cervical dilation is not the only indicator of labor induction.Cervical dilation can occur without contractions or with weak and irregular contractions, which means that labor is not established yet.
Choice C is wrong because cervical softening (or effacement) is a prerequisite for cervical dilation, but it does not necessarily mean that labor has started.Cervical softening can occur weeks before labor or even during pregnancy.
Choice D is wrong because uterine softening (or relaxation) is the opposite of what prostaglandin E2 gel is supposed to do.Uterine softening reduces the contractility and tone of the uterus, which can lead to prolonged labor or fetal distress.
Correct Answer is D
Explanation
The correct answer is choice D. Leaning slightly backwards when walking can increase the curvature of the lower spine and worsen back pain.
The other choices are helpful methods to alleviate back pain during pregnancy.
Choice A is correct because pelvic tilt exercises can strengthen the abdominal muscles and reduce the strain on the lower back.
Choice B is correct because wearing shoes with low heels can improve posture and balance and prevent excessive arching of the lower back.
Choice C is correct because sleeping on the side with a pillow beneath the knees can support the spine and pelvis and relieve pressure on the lower back.
Normal ranges for back pain during pregnancy vary depending on the individual, but some common factors that can affect it are weight gain, hormonal changes, center of gravity shift, stress and muscle separation.
