, SECTION 1: PREGNANCY PHYSIOLOGY
1. A pregnant client asks the nurse about the physiological changes that occur during pregnancy. Which cardiovascular
adaptation should the nurse identify as normal during the first trimester?
A) Decreased cardiac output
B) Decreased blood volume
C) Increased heart rate by 10-15 beats per minute
D) Decreased stroke volume
Correct Answer: C) Increased heart rate by 10-15 beats per minute
Rationale: During pregnancy, cardiac output increases by 30-50% due to increased stroke volume and heart rate. The heart rate
typically increases by 10-15 beats per minute by the third trimester. Blood volume expands by approximately 50% to meet the
metabolic demands of the growing fetus and placenta, making options A, B, and D incorrect.
2. The nurse is teaching a prenatal class about hormonal changes during pregnancy. Which hormone is primarily
responsible for maintaining the corpus luteum during early pregnancy?
A) Estrogen
B) Progesterone
C) Human chorionic gonadotropin (hCG)
D) Human placental lactogen
Correct Answer: C) Human chorionic gonadotropin (hCG)
Rationale: Human chorionic gonadotropin (hCG) is produced by the trophoblastic cells of the developing placenta and is
responsible for maintaining the corpus luteum during early pregnancy. The corpus luteum continues to produce progesterone until
the placenta takes over this function at approximately 10-12 weeks gestation.
3. A pregnant client at 28 weeks gestation reports increased shortness of breath. Which physiological change explains this
symptom?
A) Decreased oxygen consumption
B) Elevated diaphragm due to uterine enlargement
C) Decreased tidal volume
D) Reduced respiratory rate
Correct Answer: B) Elevated diaphragm due to uterine enlargement
Rationale: As the uterus enlarges during pregnancy, it pushes the diaphragm upward by approximately 4 cm, which can cause
dyspnea. Despite this mechanical change, pregnant women actually have increased tidal volume (40-50%) and minute ventilation
to meet increased oxygen demands. Shortness of breath is a common complaint in the third trimester.
4. The nurse is assessing a pregnant client's urinary system changes. Which finding should the nurse identify as a normal
physiological adaptation during pregnancy?
A) Decreased glomerular filtration rate
B) Decreased renal blood flow
C) Dilation of the ureters and renal pelvis
D) Decreased urinary frequency
Correct Answer: C) Dilation of the ureters and renal pelvis
Rationale: During pregnancy, the ureters and renal pelvis dilate due to the effects of progesterone (smooth muscle relaxation) and
mechanical compression from the enlarging uterus. Glomerular filtration rate actually increases by 50%, and renal blood flow
increases significantly. Urinary frequency increases, especially in the first and third trimesters.
