What is the significance of cervical mucus changes during the menstrual cycle?
- A. Cervical mucus changes confirm pregnancy.
- B. It becomes clear and stretchy during ovulation, indicating peak fertility.
- C. Cervical mucus changes have no relevance to fertility.
- D. It only occurs after ovulation and signals the end of fertility.
Correct Answer: B
Rationale: The correct answer is B: It becomes clear and stretchy during ovulation, indicating peak fertility. Cervical mucus changes during the menstrual cycle are important as they reflect the hormonal changes that occur. During ovulation, cervical mucus becomes clear, watery, and stretchy, resembling egg whites. This type of mucus promotes sperm survival and motility, indicating the most fertile period for conception. The other choices are incorrect because cervical mucus changes do not confirm pregnancy (A), are indeed relevant to fertility (C), and do not only occur after ovulation but actually signal peak fertility during ovulation (D).

A woman has been advised that the reason she has had a number of spontaneous abortions is because she has an inheritable mutation. Which of the following situations is consistent with this statement?
- A. A client developed skin cancer after being exposed to the sun.
- B. A client developed colon cancer from an inherited dominant gene.
- C. A reciprocal translocation was reported on a client's genetic analysis.
- D. A client's left arm failed to develop when she was a fetus.
Correct Answer: C
Rationale: Reciprocal translocations can disrupt genes and lead to recurrent miscarriages.
When assessing cervical effacement of a client in labor, the nurse assesses which characteristic?
- A. extent of opening to its widest diameter
- B. degree of thinning
- C. passage of the mucous plug
- D. fetal presenting part
Correct Answer: B
Rationale: Cervical effacement refers to the degree of thinning of the cervix, not the extent of opening. This assessment is important in determining progress in labor. The other options are not related to cervical effacement.
A woman is informed that she is a carrier for Tay-Sachs disease, an autosomal recessive illness. What is her phenotype?
- A. She has one recessive gene and one normal gene.
- B. She has two recessive genes.
- C. She exhibits all symptoms of the disease.
- D. She exhibits no symptoms of the disease.
Correct Answer: D
Rationale: Carriers of autosomal recessive diseases do not exhibit symptoms.
What is the purpose of using a GnRH antagonist in fertility treatments?
- A. To trigger ovulation directly.
- B. To prevent premature ovulation during controlled ovarian stimulation.
- C. To stimulate the growth of the uterine lining.
- D. To improve egg quality in natural cycles.
Correct Answer: B
Rationale: The purpose of using a GnRH antagonist in fertility treatments is to prevent premature ovulation during controlled ovarian stimulation. GnRH antagonists work by blocking the release of luteinizing hormone (LH), which can trigger premature ovulation. This allows for better control of the timing of ovulation in assisted reproductive techniques.
Choice A is incorrect because GnRH antagonists do not trigger ovulation directly; they prevent it. Choice C is incorrect because stimulating the growth of the uterine lining is typically achieved through other medications like estrogen. Choice D is incorrect because GnRH antagonists do not directly improve egg quality; they primarily target ovulation timing.
A nurse is providing care to a pregnant woman in labor. The woman is in the first stage of labor. When describing this stage to the client, which event would the nurse identify as the major change occurring during this stage?
- A. regular contractions
- B. cervical dilation
- C. fetal movement through the birth canal
- D. placental separation
Correct Answer: B
Rationale: The primary change during the first stage of labor is cervical dilation. Contractions occur during both the first and second stages, fetal movement through the birth canal is a major change in the second stage, and placental separation occurs in the third stage.
