The uterus is located:
- A. in the pelvic cavity;
- B. posterior to the urinary bladder;
- C. anterior to rectum;
- D. above the vagina;
Correct Answer: A
Rationale: The correct answer is A: in the pelvic cavity. The uterus is a female reproductive organ situated in the pelvic cavity. It is where the fertilized egg implants and develops during pregnancy. The uterus is located between the bladder (anteriorly) and the rectum (posteriorly). Therefore, it is not posterior to the urinary bladder (B), anterior to the rectum (C), or above the vagina (D). The correct placement of the uterus in the pelvic cavity ensures proper support and function for reproduction.
Testicular cancer usually arises from the _____.
- A. scrotal sac
- B. seminiferous tubules
- C. epididymis
- D. interstitial cells
Correct Answer: B
Rationale: The correct answer is B: seminiferous tubules. Testicular cancer arises from the cells within the seminiferous tubules where sperm production occurs. These tubules are the most common site for testicular cancer to develop. The other choices are incorrect because testicular cancer typically does not originate from the scrotal sac (A), epididymis (C), or interstitial cells (D). The scrotal sac contains the testicles but does not produce cancer, the epididymis is a different structure involved in sperm maturation, and interstitial cells produce hormones rather than sperm.
The production of testosterone in the interstitial cells is stimulated by
- A. inhibin
- B. luteinizing hormone
- C. follicl
- D. stimulating hormone
Correct Answer: B
Rationale: The correct answer is B: luteinizing hormone. Luteinizing hormone stimulates the Leydig cells in the testes to produce testosterone. Inhibin (A) regulates the production of FSH, not testosterone. Follicle-stimulating hormone (C) is responsible for sperm production in the testes, not testosterone. Thyroid-stimulating hormone (D) does not play a role in the production of testosterone.
A nurse teaches a male client how to perform a testicular self-exam in an effort to identify lumps that may be present in the testes. What does the nurse teach the client regarding normal testes size?
- A. Both testes should be the same size
- B. One testis is usually larger than the other
- C. One testis usually has a lump; the other does not
- D. Both testes usually have lumps
Correct Answer: B
Rationale: It is normal for one testicle to be slightly larger than the other.
Mucous membrane partially or completely covering the vaginal orifice is called as:
- A. Clitoris
- B. Labia
- C. Hymen
- D. Vulva
Correct Answer: C
Rationale: The correct answer is C: Hymen. The hymen is a mucous membrane that partially or completely covers the vaginal orifice. It is a thin tissue located at the opening of the vagina. The hymen can vary in appearance and may partially cover the vaginal opening, making it an essential anatomical structure to consider. The other choices are incorrect because:
A: Clitoris - The clitoris is a highly sensitive sexual organ located above the vaginal opening, not covering it.
B: Labia - The labia are the folds of skin surrounding the vaginal opening, not covering it entirely.
D: Vulva - The vulva refers to the external female genitalia, including the labia, clitoris, and vaginal opening, but it does not specifically refer to the mucous membrane covering the vaginal orifice.
