Human Reproductive System Questions
Question 1 of 5
When sexual feelings occur, it is important to
Correct Answer: A
Rationale: The correct answer is A because it emphasizes the importance of consciously choosing to act responsibly when sexual feelings arise. This involves considering the consequences, respecting boundaries, and making informed decisions. Going to a quiet place to talk (B) may not address responsible actions. Exploring feelings and doing what feels best (C) may lead to impulsive or harmful choices. Seeing a doctor (D) is not necessary for regular sexual feelings. A conscious and responsible approach promotes healthy relationships and personal well-being.
Question 2 of 5
Which is a sign of benign prostatic hyperplasia?
Correct Answer: D
Rationale: The correct answer is D: Nocturia. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, leading to urinary symptoms like frequent urination, especially at night (nocturia). Weight loss, bone pain, and fever are not typical signs of BPH. Nocturia is a common symptom due to the prostate gland pressing against the urethra, causing urinary retention. It is important to differentiate BPH symptoms from other potential causes to provide appropriate treatment.
Question 3 of 5
One treatment for erectile dysfunction requires the injection of a substance into the corpora cavernosa of the penis. The injection of which of the following causes an erection?
Correct Answer: C
Rationale: Alprostadil is the correct answer because it is a prostaglandin E1 analog that dilates blood vessels in the corpora cavernosa, promoting blood flow and causing an erection. Norepinephrine (choice A) constricts blood vessels and inhibits erection. A substance that inhibits nitric oxide formation (choice B) is counterproductive as nitric oxide is essential for vasodilation. Angiotensin II (choice D) constricts blood vessels and does not promote erection. Therefore, C is the correct choice for inducing an erection through vasodilation in the corpora cavernosa.
Question 4 of 5
As menstruation ends estrogen levels in the blood rise rapidly. What is the source of the estrogen?
Correct Answer: B
Rationale: The correct answer is B: Developing follicles. After menstruation, the developing follicles in the ovaries produce estrogen. This estrogen is responsible for thickening the endometrium in preparation for potential implantation of a fertilized egg. The corpus luteum produces progesterone, not estrogen. The endometrium is the inner lining of the uterus and is not a direct source of estrogen. Stromal cells of the ovaries are supportive cells and do not produce estrogen.
Question 5 of 5
During pregnancy, the uterine smooth muscle is quiescent. During the 9th month of gestation the uterine muscle becomes progressively more excitable. What factors contribute to the increase in excitability?
Correct Answer: B
Rationale: The correct answer is B: Progesterone synthesis by the placenta decreases. Progesterone maintains uterine quiescence during pregnancy by inhibiting uterine contractions. As progesterone levels decline towards the end of pregnancy, the uterine muscle becomes more excitable. Placental estrogen synthesis (Choice A) does not directly affect uterine excitability. Uterine blood flow (Choice C) is not a direct factor in uterine muscle excitability. Prostaglandin E2 (Choice D) actually increases towards the end of pregnancy, contributing to uterine contractions rather than decreasing excitability.
