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 couple is considering ICSI (Intracytoplasmic Sperm Injection) as part of IVF. What should the nurse explain?
- A. ICSI is only used for couples with unexplained infertility.
- B. ICSI involves injecting a single sperm directly into an egg.
- C. ICSI guarantees fertilization and successful pregnancy.
- D. ICSI eliminates the need for ovarian stimulation.
Correct Answer: B
Rationale: The correct answer is B because ICSI involves injecting a single sperm directly into an egg to facilitate fertilization. This method is used when there are issues with sperm quality or quantity. It is not limited to couples with unexplained infertility (choice A), does not guarantee successful pregnancy (choice C), and does not eliminate the need for ovarian stimulation (choice D). Therefore, choice B is the most accurate explanation of what ICSI entails.
Which situation best describes secondary infertility in a couple?
- A. Never conceived.
- B. Had repeated spontaneous abortions.
- C. Not conceived after 1 year of unprotected intercourse.
- D. Has one child but cannot conceive a second time.
Correct Answer: D
Rationale: The correct answer is D because secondary infertility refers to the inability of a couple to conceive after having one or more children without any fertility issues. This situation indicates that the couple had a successful pregnancy in the past but is now facing difficulties conceiving again.
A, B, and C are incorrect:
A: Never conceived - This does not align with the definition of secondary infertility as it involves a previous successful pregnancy.
B: Had repeated spontaneous abortions - This refers to recurrent pregnancy loss, not secondary infertility.
C: Not conceived after 1 year of unprotected intercourse - This describes primary infertility, not secondary infertility.
