A 24-year-old patient tells the nurse that she would like to use the progestin-only pill for contraception. Nursing evaluation of this patient as a candidate for the progestin-only pill includes what?

Correct Answer: C

Rationale: The correct answer is C because assessing patient reliability in taking an oral pill daily is crucial for the effectiveness of the progestin-only pill. This method requires strict adherence to a daily regimen. Asking about past childbirth (A) is not directly relevant to assessing candidacy. Assessing regular periods (B) may be important but not as critical as daily pill-taking reliability. Inquiring about past smoking habits (D) is important for overall health but not specific to progestin-only pill candidacy.

Correct Answer: B

Rationale: The correct answer is B: LH. LH, or luteinizing hormone, is primarily responsible for triggering ovulation by stimulating the release of the mature egg from the ovary. FSH (A) helps in the development of the egg, but LH is the hormone that actually induces ovulation. Progesterone (C) and Estrogen (D) are important in the menstrual cycle and pregnancy, but they do not directly trigger ovulation.

Correct Answer: C

Rationale: The correct answer is C: Acrosome. The acrosome is a structure located at the head of the sperm that contains enzymes necessary for penetrating the ovum during fertilization. These enzymes help dissolve the protective layers surrounding the ovum, allowing the sperm to enter and fertilize the egg. Choice A: Head is incorrect because the head of the sperm contains the nucleus with genetic material, not the enzymes needed for penetration. Choice B: Tail is incorrect as it is responsible for providing motility to the sperm, not for penetration. Choice D: Midpiece is incorrect as it contains mitochondria that provide energy for the sperm's movement, not enzymes for penetrating the ovum.

Correct Answer: B

Rationale: Oxytocin is the correct answer because it is the hormone responsible for milk ejection during breastfeeding. When a baby suckles, oxytocin is released, causing the muscles around the milk-producing cells to contract and push milk into the ducts. Prolactin, on the other hand, is responsible for milk production but not ejection. Estrogen and progesterone play roles in preparing the breasts for milk production but are not directly involved in milk ejection.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." The prostate gland, seminal vesicles, and bulbourethral gland all contribute to the production of seminal fluid. The prostate gland produces a milky fluid, the seminal vesicles produce a fluid rich in fructose, and the bulbourethral gland produces a clear lubricating fluid. Together, these glands provide the necessary components for semen, which is essential for sperm viability and motility. Therefore, all three glands are involved in the production of seminal fluid, making choice D the correct answer.
