The largest component of the uterus by weight is the _____.
- A. broad ligament
- B. myometrium
- C. round ligament
- D. endometrium
Correct Answer: B
Rationale: The correct answer is B: myometrium. The myometrium is the muscular layer of the uterus responsible for contractions during labor and menstruation. It is the largest component of the uterus by weight due to its thick and muscular nature. The broad ligament (A) is a sheet of peritoneum that supports the uterus and other pelvic organs. The round ligament (C) helps support the uterus and is not as significant in weight compared to the myometrium. The endometrium (D) is the inner lining of the uterus that thickens and sheds during the menstrual cycle, but it is not the largest component by weight.

Which patient does the nurse recognize as having the highest risk for ovarian cancer?
- A. A 24-year-old nulliparous woman who has a history of multiple sexual partners
- B. A 32-year-old woman who has had six live births and a history of human papilloma virus (HPV) infection
- C. A 55-year-old woman who reached menarche at age 12 and menopause at age 54
- D. A 64-year-old nulliparous woman who has taken hormone replacement therapy for 8 years
Correct Answer: D
Rationale: The correct answer is D because the patient is a 64-year-old nulliparous woman who has taken hormone replacement therapy for 8 years. Nulliparity (never giving birth) and prolonged use of hormone replacement therapy are both risk factors for ovarian cancer. Age is also a significant risk factor for ovarian cancer, with the highest incidence in women over 60.
Choice A is incorrect because although having multiple sexual partners may increase the risk of certain sexually transmitted infections, it is not a direct risk factor for ovarian cancer.
Choice B is incorrect because while HPV infection is associated with cervical cancer, it is not a known risk factor for ovarian cancer.
Choice C is incorrect because the age of menarche and menopause are not directly linked to an increased risk of ovarian cancer.
In summary, the correct answer, D, combines the highest risk factors for ovarian cancer, which are nulliparity, prolonged hormone replacement therapy, and older age.
Which of the following structures are located inferior to the prostate on either side of the membranous urethra within the deep muscles of the perineum?
- A. bulbourethral gland
- B. Seminal vesicles
- C. Ejaculatory ducts
- D. Urethral ducts
Correct Answer: A
Rationale: The correct answer is A: bulbourethral gland. These glands are located inferior to the prostate on either side of the membranous urethra within the deep muscles of the perineum. They secrete a clear mucus-like fluid that neutralizes acidic urine in the urethra.
The other choices are incorrect:
B: Seminal vesicles are located posterior to the bladder and contribute to seminal fluid production.
C: Ejaculatory ducts connect the vas deferens to the urethra and are not located in the deep muscles of the perineum.
D: Urethral ducts are not a specific anatomical structure and do not exist in this context.
The child's sex is determined by:
- A. the type of the spermatozoon that fecundates the ovule;
- B. the type of the fecundated ovule;
- C. the sex chromosome of the ovule;
- D. the sex chromosome of the spermatozoon
Correct Answer: D
Rationale: The correct answer is D because the sex of the child is determined by the sex chromosome carried by the spermatozoon that fertilizes the ovule. Sperm carries either an X or a Y chromosome, determining if the child will be male (XY) or female (XX). Choices A and B are incorrect because the type of spermatozoon or ovule does not solely determine the child's sex. Choice C is incorrect as well because the sex chromosome of the ovule alone does not determine the child's sex.
A client is having a hysterosalpingogram. What action by the nurse is most important?
- A. Assist the client in sitting up after the procedure
- B. Provide the client with a pad to avoid dye stains on the clothes.
- C. Teach her to take all antibiotics prescribed until finished
- D. Inform the client that the procedure may cause shoulder pain.
Correct Answer: A
Rationale: The correct answer is A: Assist the client in sitting up after the procedure. This is important to prevent complications like vasovagal response or fainting due to sudden positional changes. Sitting up slowly helps stabilize blood pressure and prevent dizziness.
B: Providing a pad for dye stains is not the most important action as it is a minor concern compared to client safety post-procedure.
C: Taking antibiotics has no direct relevance to the hysterosalpingogram procedure, so it is not the most important action.
D: Informing the client about potential shoulder pain is helpful, but ensuring immediate safety by assisting the client in sitting up takes precedence.
When do progesterone levels rise to their highest point during the female hormonal cycle?
- A. Between ovulation and the beginning of menstruation
- B. Immediately before ovulation
- C. When the blood concentration of luteinizing hormone is at its highest point
- D. When 12 primary follicles are developing to the antral stage
Correct Answer: A
Rationale: Progesterone levels rise to their highest point between ovulation and the beginning of menstruation because this is the luteal phase of the menstrual cycle when the corpus luteum (formed from the ruptured follicle after ovulation) secretes progesterone. This hormone prepares the endometrium for implantation and maintains a potential pregnancy.
Explanation for other choices:
- B: Immediately before ovulation, estrogen levels are high, not progesterone.
- C: Luteinizing hormone surge triggers ovulation, not directly related to progesterone rise.
- D: The development of primary follicles is associated with estrogen, not progesterone.
