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 woman who has had multiple miscarriages is advised to go through genetic testing. The client asks the nurse the rationale for this recommendation. The nurse should base his or her response on which of the following?
- A. The woman's pedigree may exhibit a mitochondrial inheritance pattern.
- B. The majority of miscarriages are caused by genetic defects.
- C. A woman's chromosomal pattern determines her fertility.
- D. There is a genetic marker that detects the presence of an incompetent cervix.
Correct Answer: B
Rationale: Genetic defects are a common cause of recurrent miscarriages.
The nurse is educating a client about hysterosalpingograms. Which information should the nurse include in her discussion prior to this procedure?
- A. This procedure is always performed under general anesthesia.
- B. This procedure should be performed after ovulation has occurred.
- C. This procedure involves instillation of a radiopaque dye into the uterine cavity.
- D. After the procedure, the client should take Tylenol to decrease cramping.
Correct Answer: C
Rationale: Rationale:
C is correct because hysterosalpingogram involves injecting a radiopaque dye into the uterine cavity to visualize the uterus and fallopian tubes. This helps identify any blockages or abnormalities.
A is incorrect as the procedure is usually done without general anesthesia.
B is incorrect as the procedure is typically scheduled in the early follicular phase.
D is incorrect as Tylenol may not be sufficient for managing post-procedure cramping.
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.
What is the role of cervical mucus observation in tracking ovulation?
- A. To confirm ovulation has already occurred.
- B. To detect peak fertility by observing changes in mucus consistency.
- C. To determine the overall health of the uterus.
- D. To predict the gender of the future baby.
Correct Answer: B
Rationale: The correct answer is B: To detect peak fertility by observing changes in mucus consistency. Cervical mucus observation is used to identify the most fertile period during a woman's menstrual cycle. This method helps in predicting ovulation by tracking changes in mucus consistency, which indicates the best time for conception. Other choices are incorrect because cervical mucus observation does not confirm ovulation has already occurred (A), determine the overall health of the uterus (C), or predict the gender of the future baby (D).
The nurse is educating a client on lifestyle changes to support fertility. Which recommendation is appropriate?
- A. Avoid caffeine and alcohol entirely.
- B. Engage in moderate exercise and maintain a balanced diet.
- C. Increase daily protein intake to boost fertility.
- D. Use herbal supplements for better ovulation.
Correct Answer: B
Rationale: The correct answer is B because moderate exercise and a balanced diet are essential for overall health, including fertility. Exercise can help regulate hormones and improve circulation to reproductive organs. A balanced diet provides necessary nutrients for optimal reproductive function.
Choice A is incorrect as complete avoidance of caffeine and alcohol is not necessary for fertility. Choice C is incorrect as excessive protein intake can negatively impact fertility. Choice D is incorrect as herbal supplements can have unknown effects on fertility and should be avoided without consulting a healthcare provider.
