A 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?

Correct Answer: B

Rationale: The correct answer is B because basal body temperature rises 1 to 5 days after ovulation, indicating that ovulation has occurred. This is important for tracking fertility and planning conception. A is incorrect because basal body temperature is not used to determine estrogen levels in cervical mucus. C is incorrect because basal body temperature is not used to diagnose uterine pathology. D is incorrect because basal body temperature does not assess blockages in the uterine cavity or fallopian tubes.

Correct Answer: D

Rationale: The correct answer is D because it demonstrates empathy, promotes open communication, and supports patient autonomy. By asking the patient to describe her feelings, the nurse can understand her emotional state, values, and beliefs, which are crucial in decision-making. This approach encourages shared decision-making and allows the nurse to provide individualized support. Choice A is incorrect because it is overly deterministic and does not consider individual circumstances. Choice B is incorrect as it simplifies the genetic risk calculation and overlooks the emotional aspect of decision-making. Choice C is incorrect as it may not respect the patient's autonomy and fails to address the emotional and ethical complexities involved in such a decision.

Correct Answer: A

Rationale: The correct answer is A: in vitro fertilization (IVF). In IVF, ova are retrieved via laparoscopy, fertilized with sperm in a lab dish, and then the resulting embryo(s) are transferred back to the woman's uterus. This process allows for fertilization to occur outside the body. Incorrect choices: B: Tubal embryo transfer (TET) involves transferring embryos directly into the fallopian tubes, not the uterus. C: Therapeutic insemination (IUI) is the process of injecting sperm directly into the uterus, not involving the removal and fertilization of ova. D: Gamete intrafallopian transfer (GIFT) involves transferring both eggs and sperm into the fallopian tubes for fertilization to occur internally, not in a lab dish.

Correct Answer: B

Rationale: The correct answer is B: Maintain a healthy weight and avoid smoking. This recommendation is most appropriate because both factors significantly impact fertility. Being at a healthy weight improves hormonal balance and ovulation, while smoking can harm sperm quality and reduce fertility. Explanation for why other choices are incorrect: A: Increasing caffeine intake may negatively affect fertility, as high levels of caffeine have been linked to reduced fertility in both men and women. C: Engaging in intensive daily exercise can actually disrupt menstrual cycles and ovulation, negatively impacting fertility. D: Focusing solely on timing of intercourse overlooks the importance of overall lifestyle factors that can affect fertility, such as diet, weight, and smoking.

Correct Answer: B

Rationale: In assessing cervical effacement during labor, the nurse should focus on the degree of thinning, which is the correct answer (B). Effacement refers to the thinning and shortening of the cervix in preparation for childbirth. This is a crucial aspect to monitor as it indicates progress in labor and readiness for the baby to descend through the birth canal. Option A, the extent of opening to its widest diameter, refers to cervical dilation, not effacement. Dilation is the measurement of how open the cervix is, while effacement is about the thinning of the cervix. Option C, passage of the mucous plug, is not directly related to cervical effacement. The mucous plug is a barrier that seals the cervix during pregnancy to protect the fetus from infections. Its passage can be a sign that labor is approaching, but it is not a direct indicator of effacement. Option D, fetal presenting part, pertains to the position of the baby's head or body in relation to the mother's pelvis, which is important for labor progress but not specifically related to cervical effacement. Understanding the distinction between cervical effacement, dilation, and other aspects of labor progress is essential for nurses and healthcare providers to effectively monitor and support women during childbirth. By knowing the specific characteristics to assess, they can provide appropriate care and interventions to promote safe and positive birth outcomes.
