A woman asks the nurse, 'What protects my baby's umbilical cord from being squashed while the baby's inside of me?' The nurse's best response is:
- A. Your baby's umbilical cord is surrounded by connective tissue called Wharton jelly, which prevents compression of the blood vessels and ensures continued nourishment of your baby.
- B. Your baby's umbilical floats around in blood anyway.
- C. You don't need to worry about things like that.
- D. The umbilical cord is a group of blood vessels that are very well protected by the placenta.
Correct Answer: A
Rationale: Wharton jelly surrounds the umbilical cord and prevents compression of the blood vessels.

An expectant mother, diagnosed with oligohydramnios, asks the nurse what this condition means for the baby. Which statement should the nurse provide for the patient?
- A. Oligohydramnios can cause poor fetal lung development.
- B. Oligohydramnios means that the fetus is excreting excessive urine
- C. Oligohydramnios could mean that the fetus has a gastrointestinal blockage
- D. Oligohydramnios is associated with fetal central nervous system abnormalities.
Correct Answer: A
Rationale: The correct answer is A: Oligohydramnios can cause poor fetal lung development. Oligohydramnios refers to a condition where there is a decreased amount of amniotic fluid surrounding the fetus. This can result in compression of the fetus leading to poor lung development. Reduced amniotic fluid levels can also increase the risk of umbilical cord compression and fetal growth restriction. Option B is incorrect as oligohydramnios actually indicates a decreased production of amniotic fluid, not excessive urine excretion by the fetus. Option C is incorrect as oligohydramnios is not directly related to gastrointestinal blockage in the fetus. Option D is incorrect as oligohydramnios is primarily associated with fetal lung and renal abnormalities, not central nervous system abnormalities.
Where does conception most commonly occur?
- A. None
- B. In the ampulla of the fallopian tube.

Correct Answer: B
Rationale: Fertilization typically occurs in the ampulla.
What condition would the nurse suspect in a patient with irregular menstrual cycles, obesity, and abnormal hair growth on the face?
- A. endometriosis
- B. hyperprolactinemia
- C. polycystic ovary syndrome
- D. hydrosalpinx
Correct Answer: C
Rationale: The correct answer is C: polycystic ovary syndrome (PCOS). Irregular menstrual cycles, obesity, and abnormal hair growth are common symptoms of PCOS. PCOS is a hormonal disorder that affects women of reproductive age. Irregular menstrual cycles occur due to anovulation. Obesity is often associated with insulin resistance, a common feature of PCOS. Abnormal hair growth, known as hirsutism, is a result of elevated levels of male hormones (androgens). Endometriosis (A) is characterized by the presence of endometrial tissue outside the uterus, causing pelvic pain and infertility. Hyperprolactinemia (B) is an excess of prolactin hormone, leading to irregular menstrual cycles and milk production. Hydrosalpinx (D) is the accumulation of fluid in a fallopian tube, causing infertility but not the symptoms described.
What is the hormone responsible for the maintenance of the endometrium during pregnancy and the maturation of mammary gland tissue?
- A. Estrogen
- B. Human chorionic gonadotropin (hCG)
- C. Prolactin
- D. Progesterone
Correct Answer: D
Rationale: The correct answer is D: Progesterone. Progesterone is essential for maintaining the endometrium during pregnancy by promoting its growth and preventing contractions. It also plays a crucial role in preparing the mammary glands for lactation. Estrogen (A) is important in the menstrual cycle but not specifically for maintaining the endometrium during pregnancy. Human chorionic gonadotropin (hCG) (B) is produced by the placenta and is primarily involved in supporting pregnancy and detecting pregnancy tests. Prolactin (C) is responsible for milk production but is not directly related to the maintenance of the endometrium or mammary gland tissue during pregnancy.
