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 D
Explanation
The correct answer is choice D. It will be necessary for a Cesarean section when labor begins.This is because a pregnant person with herpes simplex virus (HSV) type II can pass the infection to the baby during childbirth, which can be life-threatening.A Cesarean section can lower the risk of infection by avoiding contact with the virus in the genital area.
Choice A is wrong because herpes can recur after delivery, especially if the person has a history of genital herpes before pregnancy.Choice B is wrong because weekly cultures of the herpes site are not recommended during pregnancy, as they are not reliable indicators of viral shedding or risk of transmission.Choice C is wrong because it is possible to have more than one herpes outbreak during pregnancy, especially if the person has a primary or nonprimary first-episode infection in the third trimester.
Correct Answer is B
Explanation
Massaging the uterus helps it contract and prevent excessive bleeding after delivery.Uterine atony is a condition where the uterus does not contract enough to clamp the blood vessels that supply the placenta, leading to postpartum hemorrhage.Uterine massage is one of the interventions to treat uterine atony and restore uterine tone.
Choice A is wrong because having the client void frequently does not directly affect the uterine contraction.However, a full bladder can interfere with uterine contraction and cause displacement of the uterus, so it is important to monitor the bladder status and empty it as needed.
Choice C is wrong because having the client in a side-lying position for comfort does not help with uterine contraction.However, this position may be beneficial for other reasons, such as reducing edema and pain in the perineal area.
Choice D is wrong because keeping the patient on strict bed rest for 24 hours to avoid stress on the uterus does not help with uterine contraction.In fact, early ambulation after delivery can help prevent thromboembolic complications and promote recovery.
Normal ranges for postpartum blood loss are less than 500 mL for vaginal delivery and less than 1000 mL for cesarean delivery.Postpartum hemorrhage is defined as blood loss greater than or equal to 1000 mL or blood loss accompanied by signs or symptoms of hypovolemia within 24 hours after birth.
