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.

Between puberty and menopause, monthly, the following occurs :
- A. the maturation of a single secondary ovarian follicle;
- B. the transformation of a primordial follicle into a secondary one;
- C. the release of an oocyte;
- D. the release of a de Graaf follicle;
Correct Answer: C
Rationale: The correct answer is C: the release of an oocyte. During the menstrual cycle, ovulation occurs where a mature egg (oocyte) is released from the ovary. This typically happens around the middle of the cycle in response to hormonal changes. This process is essential for fertilization and pregnancy to occur.
A, B, and D are incorrect because:
A: the maturation of a single secondary ovarian follicle - This occurs before ovulation, not during the menstrual cycle.
B: the transformation of a primordial follicle into a secondary one - This is an earlier stage in follicle development, not a monthly occurrence.
D: the release of a de Graaf follicle - The Graafian follicle is the mature follicle that releases the oocyte during ovulation, not a monthly event.
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
The nurse correlates which factor to an increased risk of endometrial cancer in women with early menarche or late menopause?
- A. Total number of ovulatory cycles
- B. Less hormone stimulation
- C. Need for estrogen replacement in these patients
- D. Extended duration of the menstrual cycle in these patients
Correct Answer: A
Rationale: The correct answer is A: Total number of ovulatory cycles. Early menarche and late menopause lead to a longer reproductive period, resulting in more ovulatory cycles. Increased exposure to estrogen due to more ovulatory cycles is a risk factor for endometrial cancer. Choice B is incorrect as more hormone stimulation, not less, contributes to the risk. Choice C is irrelevant as estrogen replacement therapy is not mentioned in the question. Choice D is incorrect as the duration of the menstrual cycle is not directly linked to the increased risk of endometrial cancer in these women.
Which structure is composed of three cylindrical masses of erectile tissue each surrounded by a fibrous tissue?
- A. Testes
- B. Prostate
- C. Bladder
- D. Penis
Correct Answer: D
Rationale: The correct answer is D: Penis. The penis is composed of three cylindrical masses of erectile tissue (two corpora cavernosa and one corpus spongiosum) surrounded by fibrous tissue. The corpora cavernosa fill with blood during an erection, leading to rigidity. The other choices (A: Testes, B: Prostate, C: Bladder) do not fit the description of being composed of three cylindrical masses of erectile tissue surrounded by fibrous tissue. The testes are responsible for sperm production, the prostate is a gland that produces semen, and the bladder is a hollow muscular organ for storing urine.
Recording the strength of muscle contraction as a result of electrical stimulation is known as _________.
- A. Electromyograph
- B. Electroencephalography
- C. Electromyography
- D. Electroencephalography
Correct Answer: C
Rationale: Rationale for Correct Answer (C):
1. Electromyography (EMG) specifically measures muscle contraction strength.
2. It involves placing electrodes on the skin to record electrical activity produced by muscles.
3. EMG is commonly used in clinical and research settings to assess muscle function and diagnose neuromuscular disorders.
Summary of Incorrect Choices:
A. Electromyograph: Incorrect term, should be "Electromyography".
B. Electroencephalography: Measures brain activity, not muscle contraction.
D. Electroencephalography: Same as choice B, measures brain activity, not muscle contraction.
