What is the purpose of progesterone supplementation after embryo transfer in IVF?
- A. To induce ovulation for the next cycle.
- B. To support the uterine lining and enhance implantation success.
- C. To suppress natural hormone levels for better control.
- D. To eliminate the risk of multiple pregnancies.
Correct Answer: B
Rationale: The correct answer is B: To support the uterine lining and enhance implantation success. Progesterone supplementation is crucial after embryo transfer in IVF because it helps prepare the uterine lining for implantation and provides hormonal support to maintain a pregnancy. Progesterone is essential for the embryo to implant and for the early stages of pregnancy to progress. Therefore, the purpose of progesterone supplementation is to enhance the chances of successful implantation and support early pregnancy development.
Choices A, C, and D are incorrect:
A: To induce ovulation for the next cycle - Progesterone supplementation is not used to induce ovulation after embryo transfer in IVF. Ovulation should have already occurred before the embryo transfer.
C: To suppress natural hormone levels for better control - Progesterone supplementation is not used to suppress hormone levels but rather to support hormonal balance during the implantation phase.
D: To eliminate the risk of multiple pregnancies - Progesterone
A nurse is explaining the role of intrauterine insemination (IUI). What should the nurse include?
- A. IUI involves placing washed sperm directly into the uterus.
- B. IUI is used to treat structural abnormalities in the uterus.
- C. IUI guarantees fertilization of the egg.
- D. IUI eliminates the need for ovulation tracking.
Correct Answer: A
Rationale: The correct answer is A because intrauterine insemination (IUI) involves placing washed sperm directly into the uterus, increasing the chances of fertilization. This method bypasses potential obstacles in the reproductive tract, aiding sperm in reaching the egg. Choice B is incorrect because IUI is not primarily used to treat structural abnormalities in the uterus but rather to facilitate fertilization. Choice C is incorrect as IUI does not guarantee fertilization since other factors can still affect the success of conception. Choice D is incorrect because ovulation tracking is still important in IUI to ensure optimal timing for the procedure.
A patient asks why vitamin D is important for reproductive health. What is the nurse's response?
- A. Vitamin D is only necessary during the third trimester of pregnancy.
- B. It supports hormonal balance and may improve egg quality and implantation rates.
- C. It prevents neural tube defects in early pregnancy.
- D. Vitamin D eliminates the need for other prenatal vitamins.
Correct Answer: B
Rationale: The correct answer is B: It supports hormonal balance and may improve egg quality and implantation rates. Vitamin D plays a crucial role in reproductive health by supporting hormonal balance, which is essential for the regulation of menstrual cycles and overall reproductive function. Additionally, adequate levels of vitamin D have been associated with improved egg quality and increased success rates of implantation during conception.
Incorrect choices:
A: Vitamin D is necessary throughout pregnancy, not just during the third trimester.
C: Prevention of neural tube defects is mainly linked to folic acid intake, not vitamin D.
D: Vitamin D is important for overall health, but it does not eliminate the need for other essential prenatal vitamins that provide a variety of nutrients necessary for a healthy pregnancy.
A patient asks about the effects of smoking on male fertility. What should the nurse include in the response?
- A. Smoking increases testosterone levels, improving fertility.
- B. Smoking affects sperm count, motility, and morphology.
- C. Smoking has no significant impact on male reproductive health.
- D. Smoking only affects fertility when combined with alcohol use.
Correct Answer: B
Rationale: The correct answer is B because smoking has been proven to negatively impact male fertility by reducing sperm count, motility, and morphology. Nicotine and other harmful chemicals in cigarettes can damage sperm DNA and affect reproductive health. Choice A is incorrect as smoking actually decreases testosterone levels. Choice C is incorrect as smoking does have a significant impact on male reproductive health. Choice D is incorrect because smoking alone can still affect male fertility without the need for alcohol use.
The nurse is reviewing the medical record of a woman in labor and notes that the fetal position is documented as LSA. The nurse interprets this information as indicating which part as the presenting part?
- A. occiput
- B. face
- C. buttocks
- D. shoulder
Correct Answer: C
Rationale: The correct answer is C because in the notation LSA, the S denotes the sacrum or buttocks as the presenting part. The occiput is denoted by O, face by M, and shoulder by A.
