The mature follicle is also called a _____.
- A. Graafian follicle
- B. granulosa cell
- C. primary follicle
- D. secondary follicle
Correct Answer: A
Rationale: The correct answer is A: Graafian follicle. The mature follicle is called a Graafian follicle because it is the final stage of follicle development before ovulation. It is characterized by a fluid-filled cavity containing the oocyte. The other choices are incorrect because a granulosa cell is a type of cell found in the follicle wall, a primary follicle is an immature follicle, and a secondary follicle is an intermediate stage between the primary and Graafian follicle.

You are working as a team with an experienced nursing assistant. Considering your clients' needs for frequent assessments, monitoring, and teaching, which client is most appropriate to assign to the nursing assistant?
- A. A 34-year-old client who has just been admitted with epididymitis and an elevated temperature and needs assessment.
- B. A 43-year-old client who needs discharge teaching after having surgery to remove a stage II ovarian cancer.
- C. A 50-year-old client who has orders to ambulate in the hallway 2 days after having an abdominal hysterectomy.
- D. A 79-year-old client who is receiving continuous bladder irrigation after a transurethral resection of the prostate.
Correct Answer: C
Rationale: Ambulating a stable client is an appropriate task for a nursing assistant.
A client is concerned about her irregular menstrual periods since she has increased her daily workouts at the gym to 2 hours each day. What is the nurses best response?
- A. Do you want to talk about the need for that much exercise?
- B. Exercise is healthy but can decrease body fat and cause irregular periods. Test Bank - Medical-Surgical Nursing: Concepts for Interprofessional Collaborative Care 9e 588
- C. Bingeing and purging can cause electrolyte problems in your body.
- D. Anorexic behavior can result in decreased estrogen levels.
Correct Answer: B
Rationale: The correct answer is B. Increasing exercise intensity can lead to decreased body fat percentage, impacting hormonal balance and causing irregular periods. This is known as athletic amenorrhea. Choice A is incorrect as it does not address the physiological impact of excessive exercise on menstrual cycles. Choices C and D are also incorrect as they refer to eating disorder behaviors, which are not directly related to the client's concern of irregular periods due to increased exercise.
Neonates that are kept in 100% oxygen incubators for several days become blind when they are removed from the incubator, a condition referred to as retrolental fibroplasia. What is the explanation for the loss of sight?
- A. The high concentration of oxygen stimulates the growth of fibrous tissue into the retina
- B. The high concentration of oxygen causes rupture of blood vessels in the retina, resulting in fibrous infiltration of the vitreous humor
- C. The high concentration of oxygen retards the growth of blood vessels in the retina, but when the oxygen therapy is stopped, the fall in oxygen concentration stimulates an overgrowth of blood vessels in the retina and vitreous humor, which later become densely fibrous and block the light from the pupil
- D. The high concentration of oxygen destroys the retinal neurons
Correct Answer: C
Rationale: The correct answer is C because high oxygen concentration in neonates suppresses normal blood vessel growth in the retina. When oxygen therapy is stopped, oxygen levels fall, triggering excessive blood vessel growth in the retina and vitreous humor, leading to fibrous blockage of light. Option A suggests fibrous tissue growth due to oxygen, which is incorrect. Option B inaccurately states that oxygen causes vessel rupture. Option D is incorrect as oxygen does not directly destroy retinal neurons.
The major hormone secreted from granulosa cells is
- A. Progesterone
- B. Estrogen
- C. Testosterone
- D. Aldosterone
Correct Answer: B
Rationale: The correct answer is B: Estrogen. Granulosa cells are located in the ovarian follicles and are responsible for producing estrogen, a key female sex hormone. Estrogen plays a crucial role in the menstrual cycle, pregnancy, and development of secondary sexual characteristics. Progesterone is mainly produced by the corpus luteum, testosterone is primarily produced by the testes in males, and aldosterone is synthesized in the adrenal glands. Granulosa cells do not secrete these hormones, making choices A, C, and D incorrect.
Testosterone
- A. Boosts basal metabolic rate
- B. Influences behavior
- C. Increases bone density
- D. Increases skeletal muscle size and mass
Correct Answer: D
Rationale: Step-by-step rationale for why D is correct:
1. Testosterone is a key hormone for muscle growth.
2. It stimulates protein synthesis in muscles.
3. This leads to an increase in skeletal muscle size and mass.
4. Therefore, the correct answer is D.
Summary:
A: Testosterone does not directly boost basal metabolic rate.
B: Testosterone can influence behavior, but this is not the primary function discussed in the question.
C: Testosterone does not directly increase bone density.
