Normal Anatomy and Physiology of the Female Pelvis Questions
Question 1 of 5
The school nurse is conducting health education classes for a group of adolescents. Which statement best describes a secondary sexual characteristic?
Correct Answer: D
Rationale: The correct answer is D: Female breast development. Secondary sexual characteristics are physical changes that occur during puberty but are not directly related to reproduction. Female breast development is a classic example of a secondary sexual characteristic as it is a visible change that signals the onset of puberty. The other choices, A, B, and C, are primary sexual characteristics directly involved in reproduction such as maturation of ova, production of sperm, and external genitalia development, respectively. These are not considered secondary sexual characteristics.
Question 2 of 5
The nurse is explaining the function of the male’s cremaster muscle to a group of nursing students. Which statement accurately describes the function of the cremaster muscle?
Correct Answer: B
Rationale: The correct answer is B: Aids in temperature control of the testicles. The cremaster muscle contracts in response to cold temperatures to pull the testicles closer to the body for warmth, and relaxes in warm temperatures to move the testicles away for cooling. This mechanism helps regulate the temperature required for optimal sperm production. Explanation of why the other choices are incorrect: A: The cremaster muscle is not directly involved in transporting sperm. C: The cremaster muscle is not related to the control of urine excretion. D: The cremaster muscle does not play a role in trapping blood in the penis for an erection.
Question 3 of 5
Which hormonal effect is noted during the menstrual cycle?
Correct Answer: A
Rationale: The correct answer is A because during the menstrual cycle, LH and FSH secretion rise to stimulate ovarian follicle development and trigger ovulation. This process is crucial for maintaining the menstrual cycle. Choice B is incorrect as it is incomplete. Choice C is incorrect as negative feedback is primarily between the hypothalamus, pituitary gland, and ovaries, not just the anterior pituitary gland and ovaries. Choice D is incorrect because LH is primarily secreted by the anterior pituitary gland, not the posterior pituitary gland.
Question 4 of 5
Which statement with regard to reproductive anatomy and physiology is inaccurate?
Correct Answer: C
Rationale: The correct answer is C. Puberty symptoms are actually more prominent in females than males due to the complex hormonal changes leading to the development of secondary sexual characteristics. This is because the female reproductive system is more intricate and involves a more gradual and prolonged process compared to males. Choice A is true as sexually active females can indeed become pregnant. Choice D is also accurate as females generally enter puberty earlier than males.
Question 5 of 5
A young female patient comes to the health unit at school to discuss her irregular periods. In providing education regardinNg thRe feImalGe reBpr.odCuctMive cycle, the nurse describes the regular U S N T O and recurrent changes related to the ovaries and the uterine endometrium. Although this is generally referred to as the menstrual cycle, the ovarian cycle includes which phases? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Follicular phase. The ovarian cycle consists of two main phases: the follicular phase and the luteal phase. During the follicular phase, the ovarian follicles mature in preparation for ovulation. This phase is characterized by rising levels of estrogen. The luteal phase follows ovulation and is characterized by the formation of the corpus luteum and increased progesterone levels to support a potential pregnancy. The ovulatory phase is not a distinct phase of the ovarian cycle but rather the event of ovulation itself. Proliferative phase is a term used to describe changes in the uterine endometrium, not the ovarian cycle. Therefore, the correct answer is A, as it accurately reflects the phases of the ovarian cycle.
