A patient comes to the antepartal clinic for her visit and provides the nurse with information.
What piece of information places this patient at high risk for exposure to teratogenic agents?
She lives with two dogs at home.
She works as a part-time oncology nurse.
She is lacto-ova vegetarian.
She commutes to work on a train.
The Correct Answer is B
The correct answer is choice B. She works as a part-time oncology nurse. This is because oncology nurses are exposed to teratogenic agents, which are substances that can cause abnormalities in an exposed fetus. Teratogenic agents can cross the placenta and alter fetal morphology or function. Examples of teratogenic agents are lead, methyl mercury, polychlorinated biphenyls, lithium, vitamin K antagonists, tobacco, rubella, cytomegalovirus, ionizing agents, hyperthermia, diabetes, and some drugs.
Choice A is wrong because living with two dogs at home does not pose a high risk for exposure to teratogenic agents.Dogs can be beneficial for pregnant women as they provide companionship and exercise.
Choice C is wrong because being a lacto-ova vegetarian does not pose a high risk for exposure to teratogenic agents.Lacto-ova vegetarians can get adequate nutrition from plant-based foods, dairy products, and eggs.
Choice D is wrong because commuting to work on a train does not pose a high risk for exposure to teratogenic agents.Trains are a safe and convenient mode of transportation for pregnant women.

Correct Answer is D
Explanation
The correct answer is choice D. “Have you noticed any tenderness in your breasts?”
Breast tenderness is one of the early signs of pregnancy that may occur as early as one to two weeks after conception.It is caused by hormonal changes that prepare the breasts for lactation.
Choice A is wrong because shortness of breath is not a sign of early pregnancy.It may occur later in pregnancy due to the growing uterus pressing on the diaphragm.
Choice B is wrong because episodes of loss of consciousness are not a sign of early pregnancy.They may indicate a serious condition such as anemia, dehydration, or hypoglycemia that requires medical attention.
Choice C is wrong because spotting is not a sign of early pregnancy.
It may be a sign of implantation bleeding, which occurs when the fertilized egg attaches to the lining of the uterus.However, implantation bleeding is usually much lighter and shorter than a normal period.
Correct Answer is A
Explanation
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.
