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 A
Explanation
The correct answer is choice B. Test the patient’s vaginal secretions with nitrazine paper.
This is because the patient may be leaking amniotic fluid rather than urine, and nitrazine paper can help differentiate between the two by testing the pH level.Amniotic fluid is alkaline and will turn the paper blue, while urine is acidic and will turn the paper yellow.
Choice A is wrong because checking the patient’s bladder for distention will not help determine if the patient is leaking amniotic fluid or urine.
Choice C is wrong because checking the patient’s urine for glucose content will not help determine if the patient is leaking amniotic fluid or urine.
Glucose content may be elevated in patients with gestational diabetes, but this is not related to the patient’s complaint.
Choice D is wrong because obtaining a specimen of the patient’s vaginal secretions for culture will not help determine if the patient is leaking amniotic fluid or urine.
Culture may be done to check for infections, but this is not the initial action that the nurse should take.
Correct Answer is C
Explanation
The correct answer is choice C. Arrange for her to meet the staff who will be caring for her during labor and delivery.This measure can help reduce the anxiety and fear of the unknown that a primigravida may have in the last month of pregnancy.Meeting the staff can also help establish rapport and trust, which are essential for a positive birth experience.
Choice A is wrong because an increase in fetal activity does not necessarily require an increase in the need to rest.
Fetal activity is normal and expected, and the mother should monitor it regularly.Resting may help with some discomforts of pregnancy, but it is not directly related to fetal activity.
Choice B is wrong because back labor is not likely for a primigravida with an uncomplicated pregnancy.
Back labor occurs when the fetus is in an occiput posterior position, which puts pressure on the mother’s spine and causes intense pain in the lower back.This position is more common in multiparous women than primigravidas.
Choice D is wrong because testing urine for glucose is not a routine measure for a primigravida with an uncomplicated pregnancy.
Urine glucose testing is done for women who have gestational diabetes or are at risk of developing it.It is not necessary for women who have normal blood glucose levels.
