What is the significance of a semen analysis in evaluating infertility?
- A. It determines the number, shape, and movement of sperm.
- B. It checks for genetic conditions affecting sperm.
- C. It monitors hormone levels in males.
- D. It identifies infections in the reproductive tract.
Correct Answer: A
Rationale: The correct answer is A because a semen analysis assesses important parameters such as sperm count, morphology (shape), and motility (movement), which are crucial factors in male fertility. Sperm count indicates the quantity of sperm available for fertilization. Morphology assesses the structural integrity of sperm, while motility determines their ability to reach and fertilize an egg. These parameters directly impact fertility potential.
Choice B is incorrect because a semen analysis does not specifically check for genetic conditions affecting sperm. Choice C is incorrect as hormone levels are not directly evaluated in a semen analysis. Choice D is incorrect because while infections can affect fertility, they are not the primary focus of a standard semen analysis.

A patient asks about the purpose of egg retrieval in IVF. What should the nurse explain?
- A. Egg retrieval removes immature eggs for storage.
- B. It collects mature eggs from the ovaries for fertilization in the lab.
- C. Egg retrieval monitors ovarian reserve.
- D. It is performed after implantation to confirm pregnancy.
Correct Answer: B
Rationale: The correct answer is B: It collects mature eggs from the ovaries for fertilization in the lab.
Rationale:
1. Egg retrieval in IVF involves retrieving mature eggs from the woman's ovaries to be fertilized with sperm in a laboratory setting.
2. These fertilized eggs (embryos) are then transferred back into the uterus for potential implantation.
3. This process is crucial for successful IVF as it allows for controlled fertilization outside the body.
Summary of other choices:
A: Incorrect. Egg retrieval is not for storing immature eggs but for obtaining mature eggs for immediate fertilization.
C: Incorrect. Egg retrieval is not for monitoring ovarian reserve; this is typically done through other tests.
D: Incorrect. Egg retrieval occurs before implantation to collect eggs for fertilization, not after implantation.
The nurse is instructing a client on taking her basal body temperature. The nurse understands that this test is used to determine which of the following?
- A. If the client's cervical mucus contains enough estrogen to support sperm motility
- B. If the client's temperature rises 1 to 5 days after the midcycle
- C. If surgical correction of uterine pathology is needed
- D. If the client is experiencing blockage of the uterine cavity and the fallopian tubes
Correct Answer: B
Rationale: The correct answer is B: If the client's temperature rises 1 to 5 days after the midcycle. Basal body temperature is used to detect ovulation, which occurs when there is a rise in temperature after the midcycle. This rise indicates that ovulation has occurred. Monitoring basal body temperature is a natural family planning method.
A: Checking cervical mucus for estrogen levels is typically done to assess fertility but not related to basal body temperature.
C: Basal body temperature does not provide information on the need for surgical correction of uterine pathology.
D: Basal body temperature does not assess blockages in the uterine cavity or fallopian tubes.
A client is receiving Pergonal (menotropins) intramuscularly for ovarian stimulation. Which of the following is a common side effect of this therapy?
- A. Piercing rectal pain.
- B. Mood swings.
- C. Visual disturbances.
- D. Jerky tremors.
Correct Answer: B
Rationale: Mood swings are a known side effect of hormonal therapies like Pergonal.
A woman, who has undergone amniocentesis, has been notified that her baby is XX with a 14/21 robertsonian chromosomal translocation. The nurse helps the woman to understand which of the following?
- A. The baby will have a number of serious genetic defects.
- B. It is likely that the baby will be unable to have children when she grows up.
- C. Chromosomal translocations are common and rarely problematic.
- D. An abortion will probably be the best decision under the circumstances.
Correct Answer: C
Rationale: Robertsonian translocations are generally asymptomatic and not problematic.
The nurse educator is conducting a class for student nurses on X-linked recessive disorders. Which responses from a student nurse indicate that further education is needed?
- A. The male can't be a carrier if he doesn't have an X-linked disorder.
- B. If the male doesn't have an X-linked disorder, then his children won't either.
- C. If the female is a carrier, her daughter could be one too.
- D. If the female is a carrier, her sons may have an X-linked recessive disorder.
Correct Answer: B
Rationale: The correct answer is B because it is incorrect to assume that if a male doesn't have an X-linked disorder, then his children won't either. This statement overlooks the fact that the male could carry the recessive gene and pass it on to his daughters, who could then become carriers. This demonstrates a lack of understanding of how X-linked recessive disorders are inherited.
A: This statement is correct as males cannot be carriers of X-linked recessive disorders.
C: This statement is correct as females who are carriers have a 50% chance of passing on the recessive gene to their daughters.
D: This statement is correct as sons of carrier females have a 50% chance of inheriting the X-linked recessive disorder.
