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. Swaddle the newborn in a flexed position.This helps to reduce the symptoms of neonatal abstinence syndrome, which is what happens when babies are exposed to drugs in the womb before birth and go through drug withdrawal after birth.Swaddling can provide comfort, warmth, and security to the newborn and decrease their stress response.
Choice A is wrong because maintaining the newborn in a reverse Trendelenburg position does not help with drug withdrawal symptoms and may increase the risk of aspiration or reflux.
Choice B is wrong because gently stroking the newborn’s face and head may overstimulate the newborn and worsen their irritability and tremors.
Choice D is wrong because providing the newborn with visual stimulation may also overstimulate the newborn and increase their discomfort and agitation.
Correct Answer is C
Explanation
The correct answer is choice C. The patient should palpate her breasts using the padded sections of her fingers.This is the recommended technique for breast self-examination, as it allows the patient to feel any changes or lumps in the breast tissue.
Choice A is wrong because the patient should perform breast self-examination at the same time each month, preferably a few days after the menstrual period ends when the breasts are less likely to be swollen or tender.
Choice B is wrong because the patient should not assume that any lumps that are present in both breasts are normal.Some breast cancers can affect both breasts, and any new or unusual lumps should be reported to a doctor.
Choice D is wrong because the patient should look at her breasts while standing in front of the mirror with her arms at her sides, raised overhead, and pressed firmly on her hips.She should also look for any changes in the shape, size, color, or texture of her breasts and nipples.
