1. Which of the following best describes the primary function of the corpus
luteum during the first half of the menstrual cycle?
A) It secretes follicle-stimulating hormone to mature the ovum
B) It secretes estrogen and progesterone to prepare the endometrium
C) It produces luteinizing hormone to trigger ovulation
D) It sheds the endometrial lining during menstruation
Correct Answer: It secretes estrogen and progesterone to prepare the
endometrium
Rationale: The corpus luteum forms from the ruptured follicle after ovulation
and secretes progesterone and estrogen to prepare the endometrium for
potential implantation. FSH is secreted by the anterior pituitary, LH triggers
ovulation, and the endometrial lining is shed during menstruation if
implantation does not occur.
2. A client asks the nurse where fertilization typically occurs. What is the nurse's
best response?
A) The fundus of the uterus
B) The lower uterine segment
C) The ampulla of the fallopian tube
D) The internal cervical os
,Correct Answer: The ampulla of the fallopian tube
Rationale: Fertilization typically occurs in the ampulla, the widest portion of the
fallopian tube. The fertilized egg then travels to the uterus for implantation. The
fundus and lower uterine segment are sites for implantation, and the internal
cervical os is the opening of the cervix.
3. What is the primary function of the amniotic fluid during pregnancy?
A) To provide oxygen to the fetus
B) To cushion the fetus and help regulate temperature
C) To remove waste products from fetal blood
D) To produce red blood cells for the fetus
Correct Answer: To cushion the fetus and help regulate temperature
Rationale: Amniotic fluid cushions the fetus against mechanical injury, helps
regulate temperature, allows for fetal movement, and prevents the umbilical
cord from being compressed. Oxygen and waste exchange occur through the
placenta, and red blood cells are produced in the fetal liver and bone marrow.
4. A nurse is calculating a client's estimated date of delivery using Naegele's
Rule. The client's last menstrual period began on May 10th. What is the correct
estimated date of delivery?
A) February 3rd
, B) February 17th
C) March 3rd
D) March 17th
Correct Answer: February 17th
Rationale: Naegele's Rule is calculated by subtracting 3 months from the first
day of the last menstrual period and adding 7 days and 1 year. May 10 minus 3
months is February 10, plus 7 days is February 17. This gives an estimated date
of delivery of February 17th of the following year.
5. A client at 8 weeks gestation reports frequent urination. The nurse explains
this is primarily due to which factor?
A) Decreased kidney function
B) Pressure on the bladder from the enlarging uterus
C) Increased fluid intake
D) Urinary tract infection
Correct Answer: Pressure on the bladder from the enlarging uterus
Rationale: Early in pregnancy, the enlarging uterus presses on the bladder,
causing urinary frequency. Later in pregnancy, frequency returns when the fetal
head descends into the pelvis. Decreased kidney function, increased fluid
intake, and urinary tract infection are not the primary causes of frequency in
early pregnancy.
