The medical term expressing suture of the neck of the uterus is __________
- A. cervicography
- B. perineorrhaphy
- C. cervicorrhapy
- D. cervicorrhexis
Correct Answer: C
Rationale: The correct answer is C: cervicorrhaphy. "Cervico-" refers to the neck of the uterus, and "-rrhaphy" means suture. Therefore, cervicorrhaphy is the correct term for the procedure of suturing the neck of the uterus.
A: Cervicography is a diagnostic imaging technique, not a procedure for suturing.
B: Perineorrhaphy involves suturing the perineum, not the neck of the uterus.
D: Cervicorrhexis refers to cutting or incising the neck of the uterus, not suturing it.

Which factor causes the act of ovulation?
- A. blood pressure
- B. LH levels
- C. FSH levels
- D. estrogen
Correct Answer: B
Rationale: The correct answer is B: LH levels. Ovulation is triggered by a surge in luteinizing hormone (LH) levels, which causes the release of the mature egg from the ovary. LH surge is a key event in the menstrual cycle that leads to ovulation.
Explanation:
1. LH surge stimulates the release of the egg from the dominant follicle in the ovary.
2. This surge typically occurs around the middle of the menstrual cycle.
3. Ovulation occurs within 24-36 hours after the LH surge.
4. FSH (Choice C) is involved in follicle development but does not directly cause ovulation.
5. Estrogen (Choice D) plays a role in the menstrual cycle but does not directly trigger ovulation.
6. Blood pressure (Choice A) is not involved in the process of ovulation.
Summary: LH levels are the primary factor that causes ovulation by triggering the release of the egg from the ovary
Estrogen is required for normal reproductive function in the male. Where is the principal site of estrogen synthesis in the male?
- A. Leydig cells
- B. Osteoblasts
- C. Liver cells
- D. Prostate cells
Correct Answer: C
Rationale: Rationale:
1. The correct answer is C: Liver cells. The liver is the principal site of estrogen synthesis in the male.
2. Liver cells contain the enzyme aromatase, which converts androgens into estrogens.
3. Estrogen plays a crucial role in maintaining normal reproductive function in males.
4. Leydig cells (Choice A) are responsible for testosterone production, not estrogen synthesis.
5. Osteoblasts (Choice B) are bone cells involved in bone formation, not estrogen synthesis.
6. Prostate cells (Choice D) are involved in prostate function, not estrogen synthesis.
Which gland produces thick, clear mucus that cleanses the penile urethra of acidic urine?
- A. Testes
- B. Seminal vesicles
- C. Prostate
- D. Bulbourethral glands
Correct Answer: D
Rationale: The correct answer is D: Bulbourethral glands. These glands produce thick, clear mucus that cleanses the penile urethra of acidic urine before ejaculation. This mucus helps neutralize the acidity of urine, creating a more hospitable environment for sperm to travel through. The other choices are incorrect because:
A: Testes produce sperm, not mucus.
B: Seminal vesicles produce a fluid rich in fructose to nourish sperm.
C: Prostate produces a milky fluid that aids in sperm motility.
Which of the following nursing interventions are advised for clients with prostate cancer to avoid an infection related to the home-care of a Foley catheter?
- A. Boil the leg bag regularly in a solution of hot water and vinegar for 15 minutes during the cleaning.
- B. Disinfect several inches of the catheter with alcohol or any other antiseptic agent before the insertion.
- C. Clean the leg bag by using soap and water and then rinse it with a 1:7 solution of vinegar and water.
- D. Open the connections between the leg bag and the catheter only once in 15 days to reduce the risks of microbial entry.
Correct Answer: C
Rationale: Proper cleaning and maintenance of the catheter equipment are crucial to preventing infections.
Which vitamin is essential for bone formation?
- A. A
- B. D
- C. B
- D. K
Correct Answer: B
Rationale: The correct answer is B: Vitamin D. Vitamin D is essential for bone formation as it helps the body absorb calcium, a key mineral for bone health. Without sufficient vitamin D, the body cannot effectively utilize calcium, leading to weakened bones. Vitamin A (Choice A) is important for vision and immune function, not specifically bone formation. Vitamin C (Choice C) is crucial for collagen synthesis but not directly involved in bone formation. Vitamin K (Choice D) plays a role in blood clotting and bone mineralization but is not as directly linked to bone formation as Vitamin D.
