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. Encourage the client to drink cold, carbonated fluids throughout the day.This helps to relieve the shoulder pain caused by the carbon dioxide gas used to inflate the abdomen during laparoscopy.
The gas irritates the diaphragm, which refers pain to the shoulder.Drinking cold, carbonated fluids can help expel the gas and reduce the pain.
Choice A is wrong because an abdominal binder is not necessary for a laparoscopic procedure.It is more commonly used for abdominal surgeries that involve a large incision.
Choice B is wrong because a rocking chair is not helpful for a client who had a laparoscopic BTL.It is more useful for a client who had a vaginal delivery to promote comfort and uterine involution.
Choice C is wrong because keeping the head of the bed flat for six hours is not indicated for a laparoscopic BTL.It may increase the risk of venous thromboembolism and pulmonary embolism due to prolonged immobility.The client should be encouraged to ambulate as soon as possible after surgery.
Correct Answer is A
Explanation
The correct answer is choice A. The patient has heart disease, and the antibiotics will decrease the risk to her fetus of developing endocarditis.Endocarditis is an infection of the inner lining of the heart and valves, which can be caused by bacteria entering the bloodstream during labor and delivery.Patients with mitral valve prolapse (MVP) are more prone to develop endocarditis because their valve leaflets are floppy and do not close tightly, creating a site for bacterial attachment.Antibiotics can help prevent this complication by killing the bacteria before they reach the heart.
Choice B is wrong because pericarditis is an inflammation of the outer layer of the heart, not the inner lining or valves.It is not related to MVP or bacterial infection.
Choice C is wrong because chorioamnionitis is an infection of the membranes and fluid that surround the fetus, not the heart.It is usually caused by bacteria ascending from the vagina or cervix, not from the bloodstream.
Choice D is wrong because delivering post-term does not increase the risk of systemic infection for the fetus.Systemic infection means infection that affects multiple organs or systems in the body, not just one specific site.
