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
This is because a normal fetal heart rate is between 110 and 160 beats per minute, and the range of 136 to 143 indicates that the fetus is well-oxygenated and not experiencing hypoxia or acidosis. The nurse should reassure the patient and explain that fetal movement may decrease during labor due to the pressure of the contractions on the uterus and the fetus.
Choice A is wrong because asking the patient about alcohol consumption is irrelevant and insensitive.
Alcohol can affect fetal development and growth, but it does not directly affect fetal movement or heart rate.
Choice B is wrong because bloody vaginal discharge, or bloody show, is a normal sign of cervical dilation and effacement during labor.
It does not indicate fetal distress or placental abruption.
Choice D is wrong because explaining the relationship between anxiety and fetal movement does not address the patient’s concern or provide any factual information.
Anxiety can affect maternal perception of fetal movement, but it does not cause fetal movement to decrease.
The nurse should validate the patient’s feelings and provide factual reassurance.
Correct Answer is A
Explanation
The correct answer is choice A. A breastfed baby is likely to gain weight more rapidly in the first month of life.This statement is wrong because breastfed babies generally gain weight faster than formula-fed babies for the first 3 months of life.They also double their birth weight by 3-4 months and triple it by one year.
Therefore, a breastfed baby’s weight gain in the first month of life is not unusual or concerning.
Choice B is correct because breastfeeding is not a reliable method of birth control.A woman can still ovulate and become pregnant while breastfeeding, especially if she feeds her baby less frequently or supplements with formula or solids.
Choice C is correct because breastfeeding has been shown to reduce the risk of allergies in babies.Breast milk contains antibodies and other immune factors that protect the baby from infections and allergic reactions.
Choice D is correct because breastfeeding mothers need to drink enough fluids to stay hydrated and produce enough milk.The recommended fluid intake for breastfeeding mothers is about 13 cups (3 liters) per day.
