What is the primary structural difference between the male and female urethra?
- A. The male urethra has two functions, whereas the female urethra has one.
- B. The male urethra is up to three times as long as the female urethra.
- C. The female urethra is less protected than the male urethra.
- D. The female urethra is connected directly to the bladder.
Correct Answer: B
Rationale: The correct answer is B: The male urethra is up to three times as long as the female urethra. This is because the male urethra serves a dual function - for both urine and semen passage, requiring a longer length for transportation. In contrast, the female urethra is shorter and primarily functions for urine passage only. Choices A, C, and D are incorrect as they do not address the primary structural difference in length between the male and female urethra.
If the fundal height is halfway between the woman's symphysis pubic and umbilicus, the approximate weeks of gestation are
- A. 8
- B. 12
- C. 16
Correct Answer: B
Rationale: Fundal height correlates roughly with weeks of gestation, with 12 weeks corresponding to midway between the symphysis and umbilicus.
Which specific instruction should the nurse teach to assist a patient to regain control of her urinary sphincter?
- A. Perform Kegel exercises.
- B. C M U S N T O
- C. Void every hour while awak
Correct Answer: A
Rationale: Performing Kegel exercises strengthens the pelvic floor muscles, which can help improve urinary sphincter control. These exercises involve contracting and releasing the muscles that control urination. This instruction directly targets the issue of regaining control over the urinary sphincter. Choice B is nonsensical and irrelevant. Choice C, voiding every hour while awake, may not address the underlying muscle weakness causing the issue. Choice D is incomplete and does not provide any specific guidance on how to address the problem.
A 58-year-old postmenopausal woman presents with a sensation of pelvic heaviness and states she feels like something is sitting in her vagina. On examination, the provider notes a visible protrusion of the bladder into the anterior vaginal wall. What structural disorder of the female reproductive system is consistent with these findings?
- A. pelvic floor prolapse
- B. DES exposure
- C. vaginal septum
- D. bladder fistula
Correct Answer: A
Rationale: The correct answer is A: pelvic floor prolapse. This condition is characterized by weakening of the pelvic floor muscles and ligaments, leading to descent of pelvic organs such as the bladder into the vagina. The patient's symptoms of pelvic heaviness and sensation of something in her vagina are classic signs of pelvic floor prolapse. Examination findings of visible protrusion of the bladder into the anterior vaginal wall further support this diagnosis.
Explanation of incorrect choices:
B: DES exposure - This is not a structural disorder of the female reproductive system. DES exposure is associated with adverse effects on reproductive health but does not present with visible bladder protrusion.
C: Vaginal septum - This is a congenital anomaly where the vagina is divided by a septum. It does not typically present with bladder protrusion.
D: Bladder fistula - This is an abnormal connection between the bladder and another structure. While it can cause urinary symptoms, it does not typically present with visible bladder protrusion into the vagina.
