The hormone responsible for maturation of mammary gland tissue is:
progesterone.
testosterone.
prolactin.
estrogen.
The Correct Answer is A
Choice A reason: Progesterone is the hormone that stimulates the development of the alveoli and lobules of the mammary glands during pregnancy. It prepares the breasts for lactation by increasing the number and size of the milk-producing cells.
Choice B reason: Testosterone is the main male sex hormone that is responsible for the development of male reproductive organs and secondary sex characteristics. It has no direct role in the maturation of mammary gland tissue.
Choice C reason: Prolactin is the hormone that initiates and maintains milk production after childbirth. It is secreted by the anterior pituitary gland in response to suckling or nipple stimulation. It does not affect the maturation of mammary gland tissue.
Choice D reason: Estrogen is the hormone that stimulates the growth of the duct system of the mammary glands during puberty and pregnancy. It also promotes the development of female reproductive organs and secondary sex characteristics. It does not affect the maturation of mammary gland tissue.

Correct Answer is D
Explanation
Choice A reason: Asking the woman to reschedule the appointment for the examination is not the best response, as it may delay the detection and treatment of any potential problems. The nurse should inform the woman about the possible effect of the vaginal cream on the Pap test and offer her the option to reschedule or proceed with the examination.
Choice B reason: Asking the woman to describe the symptoms that indicate to her that she has a vaginal infection is a good way to assess the woman's condition and provide education, but it is not the initial response. The nurse should first inform the woman about the possible effect of the vaginal cream on the Pap test and then ask her about her symptoms.
Choice C reason: Reassuring the woman that using vaginal cream is not a problem for the examination is not true, as vaginal creams can alter the pH of the vaginal environment and affect the accuracy of the Pap test. The nurse should inform the woman about the possible effect of the vaginal cream on the Pap test and explain the importance of avoiding vaginal creams, douches, or intercourse for 48 hours before the test.
Choice D reason: Informing the woman that vaginal creams may interfere with the Pap test for which she is scheduled is the best response, as it educates the woman about the purpose and procedure of the Pap test and allows her to make an informed decision about whether to reschedule or proceed with the examination. The nurse should also explain the risks and benefits of both options and respect the woman's choice.
Correct Answer is D
Explanation
Choice A reason: Biophysical profile is a test that assesses the fetal well-being by measuring five parameters: fetal breathing movements, fetal movements, fetal tone, amniotic fluid volume, and fetal heart rate. It does not predict chromosomal abnormalities in the fetus.
Choice B reason: Lecithin/sphingomyelin [L/S] ratio is a test that measures the amount of two phospholipids in the amniotic fluid. It is used to evaluate the fetal lung maturity and the risk of respiratory distress syndrome. It does not predict chromosomal abnormalities in the fetus.
Choice C reason: Type and crossmatch of maternal and fetal serum is a test that determines the blood type and Rh factor of the mother and the fetus. It is used to identify the risk of hemolytic disease of the newborn due to Rh incompatibility. It does not predict chromosomal abnormalities in the fetus.
Choice D reason: Multiple-marker screening is a test that measures the levels of four substances in the maternal serum: alpha-fetoprotein, human chorionic gonadotropin, unconjugated estriol, and inhibin A. It is used to estimate the risk of Down syndrome, trisomy 18, and neural tube defects in the fetus.
