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.

One function of the placenta in a human is to
- A. surround the embryo and protect it from shock
- B. allow for mixing of maternal blood with fetal blood
- C. act as the heart of the fetus, pumping blood until the fetus is born
- D. permit passage of nutrients and oxygen from the mother to the fetus
Correct Answer: D
Rationale: The correct answer is D because the placenta serves as a barrier between the maternal and fetal bloodstreams, allowing for the exchange of nutrients, oxygen, and waste products. This is crucial for the fetus's growth and development. Choice A is incorrect because the placenta does not physically surround the embryo. Choice B is incorrect as maternal and fetal blood do not mix due to the placental barrier. Choice C is incorrect as the heart of the fetus pumps blood, not the placenta.
Corpus luteum;
- A. is generated as a result of ovulation;
- B. secretes estrogens;
- C. secrets progesterone;
- D. secrets low amounts of testosterone
Correct Answer: C
Rationale: The corpus luteum is formed from the ruptured follicle after ovulation. It secretes progesterone, which is crucial for preparing the uterus for implantation and maintaining early pregnancy. Progesterone helps thicken the uterine lining and supports embryo development. Estrogens are mainly produced by the ovaries, not the corpus luteum. Testosterone is primarily produced by the adrenal glands and testes, not the corpus luteum. Therefore, choice C is correct as it accurately describes the main hormone secreted by the corpus luteum.
Testosterone is secreted by the following structures, EXCEPT:
- A. prostate;
- B. testicular interstitial cells;
- C. seminiferous tubules;
- D. straight tubules;
Correct Answer: A
Rationale: The correct answer is A: prostate. Testosterone is primarily secreted by the testicular interstitial cells (Leydig cells) in the testes. The seminiferous tubules are responsible for spermatogenesis, not testosterone secretion. Straight tubules are involved in transporting sperm. The prostate gland produces prostatic fluid, not testosterone. Therefore, the prostate is not a structure that secretes testosterone.
Miss Tucker, aged 27, had a cervical conization for cancer in situ. She is to be married in 4 months and the couple both want children, but she has been advised to have an immediate hysterectomy. In discussing the situation with the patient the nurse should
- A. encourage her to have the hysterectomy
- B. suggest she obtain a second medical opinion
- C. suggest that she restrict sexual activity indefinitely
- D. stress the importance of repeat examinations at 3- to 6-month intervals
Correct Answer: B
Rationale: Obtaining a second opinion allows for informed decision-making regarding treatment options.
Which of the following is not a result of menopause?
- A. loss of hormones
- B. reduction in breast mass
- C. increase in calcium deposition
- D. psychological changes
Correct Answer: C
Rationale: The correct answer is C: increase in calcium deposition. Menopause is associated with a decrease in estrogen levels, leading to bone loss rather than an increase in calcium deposition. Loss of hormones (A) is a result of menopause due to the decline in estrogen and progesterone. Reduction in breast mass (B) occurs as estrogen levels decrease, impacting breast tissue. Psychological changes (D) such as mood swings and irritability are common during menopause due to hormonal fluctuations. Thus, an increase in calcium deposition is not a result of menopause, making choice C the correct answer.
