A patient with a history of mitral valve prolapse is admitted at 41 weeks gestation for induction of labor.The doctor prescribes intravenous antibiotic therapy for the patient to be given during labor.Based on this information, what is the primary reason for administering antibiotics to this patient at this time?

The patient has heart disease, and the antibiotics will decrease the risk to her fetus of developing endocarditis.

The patient has heart disease, and the antibiotics will decrease her risk of developing pericarditis.

The patient will deliver post-term, and the antibiotics will help to decrease her risk of developing chorioamnionitis.

The patient will deliver post-term, and the antibiotics will decrease the risk to her fetus of developing a systemic infection.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

The correct answer is choice C: Related to the influence of maternal hormones.This is because breast milk contains many hormones that pass into it from the mother’s body, such as prolactin, thyroid hormones, and estrogen.

These hormones can affect the baby’s growth and development, and sometimes cause temporary breast enlargement and milk secretion in newborns of both sexes.This is called neonatal galactorrhea or “witch’s milk” and it is harmless and usually resolves within a few weeks

Choice A is wrong because neonatal galactorrhea is not a symptom of an endocrine disorder.It is a normal physiological response to maternal hormones that cross the placenta during pregnancy and are present in breast milk

Choice B is wrong because neonatal galactorrhea is not related to the need for chromosomal determination of gender identity.Gender identity is determined by a complex interaction of genetic, hormonal, and environmental factors, and it is not influenced by breast milk production in newborns

Choice D is wrong because neonatal galactorrhea is not a symptom of an abnormal proliferation of mammary alveoli.

Mammary alveoli are the milk-producing cells in the breast, and they are stimulated by prolactin to secrete milk.Neonatal galactorrhea does not indicate any abnormality in the structure or function of the mammary glands

A. “Would you like to take a break for a while?”. B. “You are doing a great job. C. It’s very difficult to support someone during this part of labor.”. D. “Perhaps she’ll respond better to someone else. E. Can you call someone to help?”.

Correct Answer is B

Explanation

The correct answer is choice B. “You are doing a great job.

It’s very difficult to support someone during this part of labor.” This response acknowledges the husband’s feelings and efforts, and provides reassurance and encouragement.

It also reflects the reality that active labor can be very intense and painful for the woman, and she may not want to be touched or talked to.

Choice A is wrong because it suggests that the husband is not needed or wanted, and may make him feel rejected or useless.

Choice C is wrong because it implies that the husband is not a good support person, and may hurt his self-esteem or damage his relationship with his wife.

Choice D is wrong because it focuses on the physical aspect of labor, rather than the emotional one.

It also assumes that the woman wants medication, which may not be the case.
