Levels of transcortin are elevated in a pregnant woman. Which of the following laboratory findings would be expected in this patient?
- A. Increased total (protein-bound plus free) plasma cortisol concentration
- B. Increased free (non–protein-bound) plasma cortisol concentration
- C. Decreased total plasma cortisol concentration
- D. Decreased free plasma cortisol concentration
Correct Answer: A
Rationale: Rationale: Elevated levels of transcortin in a pregnant woman lead to an increase in total plasma cortisol concentration. Transcortin binds to cortisol, increasing its total concentration but reducing the amount of free (non-protein-bound) cortisol. Choice A is correct as total cortisol concentration increases due to transcortin binding. Choices B and D are incorrect as free cortisol concentration decreases. Choice C is incorrect as total cortisol concentration is elevated, not decreased.

Which one of the following is NOT a (vas) deferens, epididymis, component of semen?
- A. sperm
- B. epididymis, seminal glands
- C. seminal fluid
- D. prostatic fluid
Correct Answer: A
Rationale: The correct answer is A: sperm. Sperm is not a component of semen; it is the male reproductive cell. Semen is composed of fluids from the epididymis, seminal glands, and prostate, which provide nourishment, protection, and transportation for sperm. The epididymis stores and matures sperm, seminal glands produce seminal fluid, and the prostate contributes prostatic fluid. Sperm is only a part of semen and not a component of it. Therefore, choice A is the correct answer.
A nurse is teaching a client in the doctor's office about genital warts. Which of the following is the best discharge instruction to give to a client with genital warts?
- A. Advise all sexual contacts to be examined and treated.
- B. Antiviral IV drugs are recommended to prevent viral shedding.
- C. Topical applications of the antiviral drugs are recommended for clinical benefits.
- D. Use of alcohol, peroxide, witch hazel, and warm air from a hair dryer are recommended to keep the lesions dry.
Correct Answer: A
Rationale: Notifying and treating all sexual contacts is essential to prevent further spread of genital warts.
The male reproductive system arises from
- A. Paramesonephric (Mullerian) ducts
- B. Mesonephric (Wolffian) ducts
- C. FSH
- D. aldosterone
Correct Answer: B
Rationale: The correct answer is B: Mesonephric (Wolffian) ducts. The male reproductive system arises from the mesonephric ducts, which develop into structures like the epididymis, vas deferens, and seminal vesicles. The mesonephric ducts are responsible for transporting sperm from the testes to the urethra. The other choices are incorrect because A (Paramesonephric ducts) develop into the female reproductive system, C (FSH) is a hormone involved in the regulation of reproductive processes but does not directly give rise to the male reproductive system, and D (aldosterone) is a hormone involved in electrolyte balance and has no role in male reproductive system development.
When palpating the epididymis, the nurse considers which finding to be abnormal?
- A. The epididymis is located on the posterolateral surface of each testis.
- B. The epididymis feels like a tubular, comma-shaped structure.
- C. The epididymis collapses on palpation.
- D. The epididymis has an irregular, nodular surface.
Correct Answer: D
Rationale: The correct answer is D because an epididymis with an irregular, nodular surface is abnormal and may indicate a pathology such as epididymitis or a tumor. Step 1: Normal epididymis should feel smooth and firm, not irregular. Step 2: Nodular surface suggests a growth or inflammation. Step 3: Abnormal findings should prompt further evaluation. Incorrect choices: A is correct anatomical location, B describes the normal shape, and C collapsing is not a typical finding.
Inflammation of vertebra is
- A. Spondylitis.
- B. Spondylolisthesis.
- C. Spondylosis.
- D. Spondylopathy
Correct Answer: A
Rationale: Rationale:
1. Spondylitis refers to inflammation of the vertebrae, making it the correct choice.
2. Spondylolisthesis is the anterior displacement of a vertebra, not inflammation.
3. Spondylosis is degenerative changes in the spine, not inflammation.
4. Spondylopathy is a general term for any spinal disease, not specific to inflammation.
