Nokea
The fallopian tubes are:
- A. Hollow, muscular, pear-shaped organs located posterior and superior to the urinary bladder
- B. A pair of muscular tubes that extend from the left and right superior corners of the uterus to the edge of the ovaries
- C. The lower, narrow part of the uterus (womb), forming a canal that opens into the vagina, which leads to the outside of the body
Correct Answer: B
Rationale: The fallopian tubes transport eggs from the ovaries to the uterus and are the site of fertilisation.

The musculoskeletal system adapts to the changes that occur during pregnancy. A woman can expect to experience what change?
- A. Her center of gravity will shift backward.
- B. She will have increased lordosis.
- C. She will have increased abdominal muscle tone.
- D. She will notice decreased mobility of her pelvic joints.
Correct Answer: B
Rationale: An increase in the normal lumbosacral curve (lordosis) develops, and a compensatory curvature in the cervicodorsal region develops to help the woman maintain her balance.
During a patient's physical examination, the nurse notes that the lower uterine segment is soft on palpation. The nurse would document this finding as:
- A. Hegar's sign
- B. McDonald's sign
- C. Chadwick's sign
- D. Goodell's sign
Correct Answer: A
Rationale: Hegar's sign refers to the softening and compressibility of the lower uterine segment, typically occurring around 6 weeks of gestation.
What is true of family-centered care? (Select one that does not apply.)
- A. The nurse's role is to enter into a partnership with the family.
- B. The health care professionals are the primary decision makers.
- C. The family's involvement during pregnancy and birth is seen as constructive necessary for bonding and support.
- D. Families contribute their ability to accept and maintain control over the health care of family members.
Correct Answer: B
Rationale: Family-centered care emphasizes collaboration between healthcare providers and families, recognizing the family's crucial role in patient care and decision-making.
Cardiovascular system changes occur during pregnancy. Which finding would be considered normal for a woman in her second trimester?
- A. Less audible heart sounds (S1, S2)
- B. Increased pulse rate
- C. Increased blood pressure
- D. Decreased red blood cell (RBC) production
Correct Answer: B
Rationale: Between 14 and 20 weeks of gestation, the pulse increases about 10 to 15 beats/min, which persists to term.
The decrease in systemic vascular resistance aids in decreasing which physiological measure?
- A. Cardiac output
- B. Pulse rate
- C. Renal blood flow
- D. Blood pressure
Correct Answer: D
Rationale: The decrease in systemic vascular resistance leads to a decrease in blood pressure for the following reasons: 1. Vasodilation reduces resistance to blood flow in the blood vessels, lowering overall pressure. 2. As resistance decreases, the heart doesn't have to work as hard to pump blood, resulting in a decrease in blood pressure. 3. Lower resistance allows blood to flow more easily, reducing pressure on the arterial walls. The other choices are incorrect because: A: Decreasing systemic vascular resistance would typically increase cardiac output, not decrease it. B: Pulse rate is primarily affected by factors like sympathetic nervous system activity and not directly by changes in vascular resistance. C: Renal blood flow is more influenced by factors like renal artery pressure and hormonal regulation, rather than changes in systemic vascular resistance.
