A man is taking a number of medications, one of which appears to be interfering with the emission phase of the sexual act. Which of the following medications could cause this problem?
- A. A medication that prolongs the duration of action of nitric oxide
- B. A medication that blocks the smooth muscle receptors for nitric oxide
- C. A medication that increases the release of nitric oxide
- D. A testosterone-like androgen compound
Correct Answer: B
Rationale: The correct answer is B because blocking the smooth muscle receptors for nitric oxide would interfere with vasodilation necessary for an erection during the emission phase of the sexual act. Choice A would actually enhance the effects of nitric oxide, Choice C would increase nitric oxide release which would typically improve sexual function, and Choice D, a testosterone-like androgen compound, would not directly affect the emission phase related to nitric oxide.

Where does fertilization usually occur in the female reproductive system?
- A. Ovary
- B. Vesicular (Graafian) follicle
- C. Uterine (fallopian) tubes
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C, the uterine (fallopian) tubes. This is where fertilization usually occurs as it is the site where the egg and sperm meet. The egg is released from the ovary and travels through the fallopian tube where it can be fertilized by sperm. If fertilization occurs, the resulting embryo will then travel to the uterus for implantation. The other choices are incorrect because fertilization does not typically occur in the ovary (A) or vesicular (Graafian) follicle (B). While the uterus (D) is where the embryo implants and develops into a fetus, fertilization itself does not occur there.
A client is learning how to maintain optimum bladder function. Which of the following strategies identifies the method of pressing on the bladder while seated on the toilet?
- A. Valsalva maneuver
- B. Kegel maneuver
- C. Pelvic floor maneuver
- D. Crede's maneuver
Correct Answer: D
Rationale: Crede's maneuver involves applying manual pressure to the bladder to aid in voiding.
In order for milk to flow from the nipple of the mother into the mouth of the nursing infant, which of the following must occur?
- A. Myoepithelial cells must relax
- B. Prolactin levels must fall
- C. Oxytocin secretion from the posterior pituitary must take place
- D. The baby’s mouth must develop a strong negative pressure over the nipple
Correct Answer: C
Rationale: The correct answer is C because oxytocin is responsible for stimulating the contraction of myoepithelial cells around the alveoli in the mammary glands, causing milk ejection. This process is known as the let-down reflex. In contrast, choice A (myoepithelial cells must relax) is incorrect because they need to contract to push milk out. Choice B (prolactin levels must fall) is incorrect because prolactin is responsible for milk production, not milk ejection. Choice D (the baby's mouth must develop a strong negative pressure over the nipple) is incorrect because it is the mother's hormone release, not the baby's action, that causes milk flow.
A mother asks a nurse when her daughter should get immunized again for human papilloma virus (HPV). What is the nurse’s most appropriate response to this question?
- A. Your daughter does not need this immunization until she becomes sexually active.
- B. The recommended age for this immunization is between 25 and 30 years of age.
- C. Between the ages of 11 and 26 years is the recommended time for this immunization.
- D. When she begins having menstrual periods is the best time for this immunization.
Correct Answer: C
Rationale: The correct answer is C: Between the ages of 11 and 26 years is the recommended time for this immunization. The HPV vaccine is recommended for females aged 11-26 to prevent HPV infections, which can lead to cervical cancer. Starting vaccination early provides the best protection before potential exposure to the virus. Option A is incorrect as waiting until sexual activity can leave the individual vulnerable to HPV. Option B is incorrect as the recommended age range is 11-26, not 25-30. Option D is incorrect as the timing of menstrual periods is not a factor in determining when to get the HPV vaccine.
Why is rupturing of the hymen not considered a confirmation of loss of virginity?
- A. Because the hymen is not affected by any sexual activity
- B. Because the hymen can be perforated during physical activity, insertion of a tampon, or pelvic examination.
- C. Because the hymen is ruptured the first time a person urinates.
- D. Because the hymen is very delicate and may be ruptured even when running or doing strenuous exercises.
Correct Answer: B
Rationale: The hymen can be perforated by various non-sexual activities, making it an unreliable indicator of virginity.
