What action is specific to hormonal contraceptives and should be taught to this woman?
- A. The cervical mucus is made resistant to penetration by sperm.
- B. The release of follicle-stimulating hormone is increased to block fertility.
- C. The maturation of the endometrial lining is activated by the contraceptive.
- D. The pituitary gland increases the synthesis and release of luteinizing hormone.
Correct Answer: A
Rationale: The correct action specific to hormonal contraceptives that should be taught to the woman is that they alter cervical mucus to prevent sperm penetration. This mechanism helps in preventing pregnancy by reducing the chances of sperm reaching the egg. Choices B, C, and D are incorrect. Choice B is inaccurate as hormonal contraceptives work by inhibiting ovulation rather than increasing follicle-stimulating hormone release. Choice C is incorrect as hormonal contraceptives do not activate the maturation of the endometrial lining; instead, they modify it to prevent implantation. Choice D is also incorrect as hormonal contraceptives do not stimulate the pituitary gland to increase luteinizing hormone synthesis and release.
