The nurse is instructing a patient on the use of depot medroxyprogesterone acetate. Which statements are correct? (Select one that doesn't apply.)

Correct Answer: A

Rationale: Correct Answer: A Rationale: Depot medroxyprogesterone acetate is a progestin-only contraceptive that commonly causes changes in menstrual patterns. By inhibiting ovulation, it can lead to irregular bleeding, amenorrhea, or spotting. Patients should be informed about these potential changes. Increasing calcium intake is not specifically related to this medication. While patients can experience irregular bleeding initially, it is not accurate to say they do not have any changes in their periods. Depot medroxyprogesterone acetate is safe to use while breastfeeding, as it does not affect milk production or quality.

Correct Answer: D

Rationale: The correct answer is D: Proliferative phase. During this phase, which occurs after the menstrual phase, the endometrium thickens and becomes more vascularized in preparation for potential implantation of a fertilized egg. This phase is characterized by the repair and growth of the endometrium, making it the correct choice. A: Follicular phase - This phase occurs before ovulation and is primarily focused on follicle development, not endometrial repair and growth. B: Luteal phase - This phase occurs after ovulation and is mainly associated with the formation and maintenance of the corpus luteum, not endometrial repair and growth. C: Menstrual phase - This phase involves shedding of the endometrium, not repair and growth.

Correct Answer: D

Rationale: The correct answer is D: Leydig cells. Leydig cells are located in the testes and are responsible for producing testosterone in males. Testosterone is a key hormone for male development and reproductive function. The other choices (A: Epididymis, B: Seminiferous tubules, C: Prostate gland) are not involved in testosterone production. The epididymis stores and transports sperm, seminiferous tubules produce sperm, and the prostate gland secretes fluids that nourish and protect sperm. Therefore, Leydig cells are the correct choice for testosterone production in males.

Correct Answer: C

Rationale: The correct answer is C: Estrogen. Estrogen is the major hormone responsible for the development of secondary sexual characteristics in females. It promotes breast development, regulates the menstrual cycle, and influences body fat distribution. Progesterone (A) is involved in preparing the uterus for pregnancy. Testosterone (B) is the primary male sex hormone, but it also plays a role in female secondary sexual characteristics. Prolactin (D) is primarily responsible for milk production in females, not the development of secondary sexual characteristics.

Correct Answer: B

Rationale: The correct answer is B: Ovaries. The ovaries are the primary site of estrogen production in females. Estrogens are steroid hormones produced mainly by the developing ovarian follicles. The adrenal gland (A) primarily produces hormones like cortisol and aldosterone, not estrogen. The pituitary gland (C) releases hormones that regulate the ovaries but does not produce estrogen directly. The uterus (D) is the site where the fertilized egg implants and grows during pregnancy, but it does not produce estrogen.
