What is the purpose of intracytoplasmic sperm injection (ICSI) in IVF procedures?
- A. To allow multiple sperm to fertilize an egg for better results.
- B. To assist fertilization by injecting a single sperm directly into an egg.
- C. To ensure ovulation occurs during stimulation cycles.
- D. To bypass ovarian stimulation entirely.
Correct Answer: B
Rationale: The correct answer is B, to assist fertilization by injecting a single sperm directly into an egg. In ICSI, a single sperm is carefully selected and injected into an egg to aid fertilization, particularly in cases of male infertility. This method ensures that fertilization occurs successfully by bypassing natural barriers. Choice A is incorrect as multiple sperm fertilizing an egg can lead to genetic abnormalities. Choice C is incorrect as ovulation is induced before egg retrieval, not during stimulation cycles. Choice D is incorrect as ovarian stimulation is necessary to produce multiple eggs for retrieval.

A client's basal body temperature (BBT) chart for one full month is shown below. Based on the temperatures shown, what can the nurse conclude?
- A. It is likely that she has not ovulated.
- B. The client's fertile period is between 12 and 18 days.
- C. The client's period is abnormally long.
- D. It is likely that her progesterone levels rose on day 15.
Correct Answer: D
Rationale: A biphasic BBT pattern indicates ovulation, with rising temperatures reflecting progesterone elevation.
A nurse is teaching a group about the benefits of folic acid supplementation before conception. What should the nurse emphasize?
- A. Folic acid helps prevent neural tube defects in the developing fetus.
- B. Folic acid improves the chances of multiple pregnancies.
- C. Folic acid is only needed during the third trimester of pregnancy.
- D. Folic acid reduces the need for prenatal vitamins.
Correct Answer: A
Rationale: The correct answer is A: Folic acid helps prevent neural tube defects in the developing fetus. The rationale is that folic acid is essential for the development of the neural tube in early pregnancy, which is crucial for the baby's brain and spinal cord formation. By emphasizing this benefit, the nurse educates about the importance of folic acid before conception to reduce the risk of neural tube defects. Choices B, C, and D are incorrect because folic acid does not improve chances of multiple pregnancies, is needed before conception and throughout pregnancy (not just in the third trimester), and is a supplement that complements prenatal vitamins rather than replacing them.
Which diagnostic test is commonly used to evaluate the structure and patency of the uterus and fallopian tubes?
- A. Semen analysis.
- B. Endometrial biopsy.
- C. Hysterosalpingography.
- D. Testicular biopsy.
Correct Answer: C
Rationale: The correct answer is C: Hysterosalpingography. This test involves injecting a contrast dye into the uterus and fallopian tubes to evaluate their structure and patency. It helps diagnose issues like blockages or abnormalities. Semen analysis (A) is used to evaluate male fertility, not the uterus or fallopian tubes. Endometrial biopsy (B) is used to evaluate the uterine lining, not the structure of the uterus or fallopian tubes. Testicular biopsy (D) is used to assess male reproductive health, not female reproductive structures. Therefore, C is the correct choice for evaluating the structure and patency of the uterus and fallopian tubes.
A client is to receive Pergonal (menotropins) injections for infertility prior to in vitro fertilization. Which of the following is the expected action of this medication?
- A. Prolongation of the luteal phase.
- B. Stimulation of ovulation.
- C. Suppression of menstruation.
- D. Promotion of cervical mucus production.
Correct Answer: B
Rationale: Pergonal stimulates ovulation by promoting the maturation and release of ova.
Cindy, a 36-year-old, has been prescribed Follistim AQ, a follitropin. What information should the nurse include in Cindy's education?
- A. Eggs or oocytes develop within ovarian follicles. The purpose of the medication is to stimulate development of ovarian follicles.
- B. Follistim is a manufactured form of FSH, a hormone released from the pituitary gland during the menstrual cycle.
- C. Rapid weight gain is typical during ovulation induction.
- D. Typical side effects include breast tenderness, changes in mood, and depression.
Correct Answer: A
Rationale: The correct answer is A. Cindy is prescribed Follistim AQ to stimulate the development of ovarian follicles, where eggs or oocytes develop. This medication helps in ovulation induction. The nurse should educate Cindy on the medication's purpose, how it works, and the importance of follicle development in the ovulation process.
Choice B is incorrect as Follistim is not a manufactured form of FSH but a specific form of follitropin.
Choice C is incorrect as rapid weight gain is not a typical side effect of ovulation induction with Follistim.
Choice D is incorrect as the typical side effects of Follistim include ovarian hyperstimulation syndrome, abdominal pain, and bloating, not breast tenderness, changes in mood, or depression.
