A 67-year-old male client had serum laboratory tests performed during his annual examination. The nurse reviews his results, as
- A. specific antigen: 10 ng/mL (10 mcg/L); prolactin: 5 ng/mL (217.4 pmol). What action by the nurse is best?
- B. Assess for possible galactorrhea with breast discharg
- C. Note the possibility of a testicular tumor.
- D. Communicate that results were normal.
Correct Answer: D
Rationale: The correct answer is D. The nurse should communicate that the results were normal because the specific antigen and prolactin levels fall within the normal range for a 67-year-old male. Specific antigen levels around 10 ng/mL are typical for this age group, and prolactin levels of 5 ng/mL are also within normal limits. Option A is not necessary as the results are normal. Option B is incorrect as galactorrhea is not indicated by the lab results. Option C is also incorrect as there is no indication of a testicular tumor based on the lab values. Therefore, the best course of action is to inform the client that the results are normal.

Which of the following is NOT a sexually transmitted disease?
- A. Syphilis
- B. Gonorrhea
- C. Cough
- D. Genital Warts
Correct Answer: C
Rationale: The correct answer is C: Cough. Sexually transmitted diseases (STDs) are transmitted through sexual activity, not through coughing. Syphilis (A), Gonorrhea (B), and Genital Warts (D) are all STDs that are transmitted through sexual contact. Cough (C) is not a sexually transmitted disease as it is typically spread through respiratory droplets. Therefore, C is the correct answer as it does not fit the criteria of being an STD.
Which condition in men is termed as Nongonococcal urethritis?
- A. Chlamydia
- B. Gonorrhea
- C. Herpes
- D. Syphilis
Correct Answer: A
Rationale: The correct answer is A: Chlamydia. Nongonococcal urethritis is primarily caused by Chlamydia trachomatis, a common sexually transmitted infection. Chlamydia is a major cause of urethritis in men. Gonorrhea (choice B) is another sexually transmitted infection but is not classified as nongonococcal urethritis. Herpes (choice C) and Syphilis (choice D) are caused by different pathogens and present with distinct symptoms, not typically associated with urethritis. Therefore, Chlamydia is the correct choice for Nongonococcal urethritis.
Which of the following is an example of ovoviviparity?
- A. Honeybees lay soft eggs within the hive
- B. Sharks hatch from shell-covered fertilized eggs within the female's body.
- C. Birds hatch from shell covered fertilized eggs laid within a nest.
- D. Fetal mammals obtain nourishment from the mother through a placent
Correct Answer: C
Rationale: Ovoviviparity is a reproductive strategy where fertilized eggs develop within the female's body but are not nourished by the mother. Choice C is correct because birds lay fertilized eggs within a nest where they hatch, indicating the eggs were developed internally. Choice A is incorrect as honeybees do not exhibit ovoviviparity. Choice B is incorrect as sharks exhibit viviparity, where embryos develop inside the mother but are nourished directly. Choice D is incorrect as it describes placental nourishment in mammals, which is not characteristic of ovoviviparity.
Testosterone is converted to _____ in the prostate.
- A. cholesterol
- B. estrogen
- C. progesterone
- D. dihydrotestosterone
Correct Answer: D
Rationale: The correct answer is D: dihydrotestosterone. Testosterone is converted to dihydrotestosterone (DHT) in the prostate by the enzyme 5-alpha reductase. DHT is a more potent androgen that plays a crucial role in prostate growth and development. Choice A (cholesterol) is incorrect as it is not a product of testosterone conversion in the prostate. Choice B (estrogen) is incorrect as testosterone is not directly converted to estrogen in the prostate. Choice C (progesterone) is incorrect as progesterone is not the main product of testosterone conversion in the prostate.
Cowper's gland is another name for:
- A. Prostate gland
- B. Testes
- C. Bulbourethral glands
- D. Preputial glands
Correct Answer: C
Rationale: The correct answer is C: Bulbourethral glands. Cowper's gland is another name for the bulbourethral glands, which are responsible for producing a lubricating fluid that helps neutralize acidity in the urethra before ejaculation. The prostate gland (A) is responsible for producing seminal fluid, the testes (B) are responsible for producing sperm, and the preputial glands (D) are glands found in the foreskin of the penis. Therefore, the bulbourethral glands (C) are the correct answer because they align with the function and location of Cowper's gland.
