Question 1 of 5
The physician diagnoses a 3-cm cyst in the ovary of a 28-year-old patient. You expect the initial treatment to include
Correct Answer: C
Rationale: The correct answer is C because examining the patient after her next menstrual period allows for monitoring the cyst's size and nature. This approach is conservative and avoids unnecessary interventions like hormone therapy or surgery. Monitoring the cyst over time can help determine if it is benign or requires further treatment. Initiating hormone therapy (choice A) is not necessary at this point and may not address the cyst. Scheduling a laparoscopy to remove the cyst (choice B) is invasive and premature without first observing the cyst's behavior. Waiting for the next menstrual period allows for a more informed decision-making process based on the cyst's response to hormonal changes.
Question 2 of 5
Before the nurse encourages this patient to begin annual screening, it is important for her to understand the reasons why women avoid testing. These reasons include which of the following? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Expense of the procedure. This is correct because cost can be a significant barrier to healthcare access, including screening tests. Women may avoid testing due to financial constraints. A: Fear of x-ray exposure is not typically a reason for avoiding annual screening, as modern screening methods use minimal radiation. C: Reluctance to hear bad news may be a concern, but it is not a common reason for avoiding testing altogether. D: Having heard that the test is painful is not a typical reason for avoiding annual screening, as most screening tests are not painful.
Question 3 of 5
What is the primary function of the endometrial layer of the uterus?
Correct Answer: B
Rationale: The correct answer is B: Prepare to receive and nourish a fertilized ovum (blastocyst). The primary function of the endometrial layer of the uterus is to provide a suitable environment for implantation and nourishment of a fertilized egg. During the menstrual cycle, the endometrial layer thickens in preparation for potential pregnancy. If fertilization occurs, the blastocyst implants into the endometrium for further development. Choices A, C, and D are incorrect as the endometrial layer does not primarily function to increase in density during each cycle, produce ovulation-regulating hormones, or maintain pregnancy, respectively.
Question 4 of 5
What is the primary function of the corpus luteum?
Correct Answer: B
Rationale: The primary function of the corpus luteum is to produce progesterone and estrogen. Progesterone supports the maintenance of the endometrium for potential implantation of a fertilized egg. Estrogen also plays a role in the menstrual cycle. The other choices are incorrect because: A: The ovum is produced in the ovary, not the corpus luteum. C: The endometrial growth is primarily influenced by estrogen and progesterone, not the corpus luteum. D: The maturation of the next follicle is regulated by hormones like follicle-stimulating hormone (FSH) and luteinizing hormone (LH), not the corpus luteum.
Question 5 of 5
The myometrium of the uterus responds to which hormone?
Correct Answer: A
Rationale: The correct answer is A: Prostaglandins and oxytocin. Prostaglandins and oxytocin are the primary hormones that stimulate contractions in the myometrium of the uterus during labor. Progesterone and estrogen (choice B) are involved in the menstrual cycle and maintaining pregnancy, not in uterine contractions. Oxytocin, relaxin, and prostaglandin E (choice C) have roles in labor but are not the primary hormones that directly act on the myometrium. Progesterone and testosterone (choice D) do not directly influence uterine contractions.
