A pregnant patient asks the nurse why her provider prescribed progesterone supplements. The nurse explains that progesterone is important because it
Prevents uterine contractions to reduce the risk of miscarriage.
Stimulates fetal lung development.
Promotes dilation of the cervix during labor.
Increases milk production after delivery.
The Correct Answer is A
A. Prevents uterine contractions to reduce the risk of miscarriage: Progesterone maintains uterine quiescence by relaxing smooth muscle and preventing premature contractions. It also supports implantation and sustains the endometrial lining, reducing the risk of early pregnancy loss and promoting fetal development.
B. Stimulates fetal lung development: Fetal lung maturity is primarily stimulated by corticosteroids, not progesterone. Betamethasone or dexamethasone is often administered to enhance surfactant production when preterm birth is anticipated.
C. Promotes dilation of the cervix during labor: Cervical dilation occurs due to increased prostaglandin activity and estrogen levels near term, not progesterone. In fact, progesterone helps maintain cervical firmness and closure during early and mid-pregnancy.
D. Increases milk production after delivery: Milk production is stimulated by prolactin following delivery when progesterone and estrogen levels drop. High progesterone during pregnancy actually inhibits lactation by blocking prolactin’s action on mammary glands.

Correct Answer is ["On her left side"]
Explanation
Sleeping on the left side enhances venous return and optimizes uteroplacental blood flow by preventing compression of the inferior vena cava and aorta by the gravid uterus. This position promotes better oxygen and nutrient delivery to the fetus while reducing maternal hypotension, dizziness, and edema. Supine or right-side sleeping can impair circulation, leading to decreased cardiac output and fetal perfusion, especially in later pregnancy.
Correct Answer is D
Explanation
A. Secondary dysmenorrhea: Although secondary dysmenorrhea involves painful menstruation caused by pelvic pathology, it is a broad term. Endometriosis is a specific cause of secondary dysmenorrhea, but the additional symptoms of infertility and dyspareunia suggest a more defined diagnosis.
B. Primary dysmenorrhea: Primary dysmenorrhea typically begins during adolescence and is caused by excessive prostaglandin production leading to uterine contractions. It does not usually worsen over time or cause infertility and pain during intercourse.
C. PMS: Premenstrual syndrome is characterized by mood swings, breast tenderness, bloating, and fatigue occurring before menstruation. It does not cause severe pelvic pain, dyspareunia, or infertility, which are hallmark features of endometriosis.
D. Endometriosis: Endometriosis occurs when endometrial tissue grows outside the uterus, leading to chronic inflammation, scarring, and adhesions. It commonly causes progressive dysmenorrhea, deep dyspareunia, chronic pelvic pain, and infertility, aligning closely with this patient’s symptoms.
