What is not a true statement concerning the vagina?
- A. The vagina serves as the birth canal.
- B. The distal end of the vagina is partially enclosed by the hymen.
- C. The vagina is the female organ of copulation.
- D. The innermost lining of the vagina sloughs off periodically.
Correct Answer: D
Rationale: The correct answer is D because the innermost lining of the vagina does not slough off periodically like the uterine lining does during menstruation. The vaginal lining is composed of stratified squamous epithelium that does not undergo the shedding process seen in the endometrium. This is important for maintaining the integrity and functionality of the vagina. Choices A, B, and C are true statements about the vagina. A: The vagina serves as the birth canal. B: The distal end of the vagina is partially enclosed by the hymen. C: The vagina is the female organ of copulation.

Which of the following portions of the placenta secretes HCG?
- A. Syncytiotrophoblast
- B. Cytotrophoblast
- C. Endometrium
- D. Chorion
Correct Answer: A
Rationale: The correct answer is A: Syncytiotrophoblast. This layer of the placenta secretes human chorionic gonadotropin (HCG), a hormone crucial for maintaining pregnancy by supporting the corpus luteum to produce progesterone. Syncytiotrophoblast is a multinucleated layer formed from the fusion of cytotrophoblast cells and is responsible for hormone secretion.
B: Cytotrophoblast is the inner layer of the trophoblast but does not secrete HCG.
C: Endometrium is the lining of the uterus and is not part of the placenta.
D: Chorion is a membrane that contributes to the formation of the placenta but does not secrete HCG.
While giving a history, a patient reports having a weak urinary stream and feeling that his bladder is not empty after urination. Based on these data, what finding does the nurse anticipate upon examination?
- A. An enlarged prostate gland palpated on the anterior wall of the rectum
- B. An indirect hernia palpated through the inguinal ring when the patient coughs
- C. The foreskin of the penis cannot be returned to position after retraction behind the glans
- D. A nodular prostate gland palpated on the posterior wall of the rectum
Correct Answer: A
Rationale: The correct answer is A: An enlarged prostate gland palpated on the anterior wall of the rectum. In this case, the patient's weak urinary stream and feeling of incomplete bladder emptying are classic symptoms of benign prostatic hyperplasia (BPH). During a rectal examination, an enlarged prostate gland can be felt as a smooth, rubbery, and symmetrically enlarged mass on the anterior wall of the rectum. This finding correlates with the patient's urinary symptoms, indicating obstruction of the urethra by the enlarged prostate.
Choice B is incorrect because an indirect hernia is not typically associated with urinary symptoms. Choice C is incorrect as it describes paraphimosis, a condition where the foreskin cannot be returned to its original position. Choice D is incorrect as a nodular prostate gland palpated on the posterior wall of the rectum is more characteristic of prostate cancer rather than BPH, which is typically felt on the anterior wall.
