1. What action is specific to hormonal contraceptives and should be taught to this woman?
- A. The cervical mucus is altered to prevent sperm penetration.
- 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.
2. A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary therapeutic action of this medication?
- A. It stimulates the formation of new bone.
- B. It decreases bone resorption and increases bone density.
- C. It increases calcium absorption in the intestines.
- D. It increases the excretion of calcium through the kidneys.
Correct answer: B
Rationale: The correct answer is B. Raloxifene works by decreasing bone resorption and increasing bone density, which helps in the prevention and treatment of osteoporosis. Choice A is incorrect as raloxifene does not directly stimulate the formation of new bone. Choice C is incorrect because raloxifene does not primarily affect calcium absorption in the intestines. Choice D is incorrect as raloxifene does not increase the excretion of calcium through the kidneys.
3. A patient has been prescribed raloxifene (Evista) for the prevention of osteoporosis. What effect should the nurse include in the teaching plan regarding the action of this medication?
- A. Decreases calcium excretion by the kidneys.
- B. Increases intestinal absorption of calcium.
- C. Stimulates bone formation by increasing osteoblast activity.
- D. Selectively binds to estrogen receptors, decreasing bone resorption.
Correct answer: D
Rationale: The correct answer is D: Selectively binds to estrogen receptors, decreasing bone resorption. Raloxifene is a selective estrogen receptor modulator (SERM) that works by binding to estrogen receptors, thereby decreasing bone resorption. This action helps in the prevention and treatment of osteoporosis by preserving bone density. Choices A, B, and C are incorrect because raloxifene does not directly affect calcium excretion by the kidneys, intestinal absorption of calcium, or stimulate bone formation by increasing osteoblast activity.
4. A patient is taking medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse include in the patient teaching?
- A. Take the medication with food to prevent gastrointestinal upset.
- B. Avoid prolonged sun exposure while taking this medication.
- C. Take the medication at the same time each day to maintain consistent hormone levels.
- D. Discontinue the medication if side effects occur.
Correct answer: C
Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels. This is important for the effectiveness of medroxyprogesterone acetate. Choice A is incorrect because medroxyprogesterone acetate does not need to be taken with food. Choice B is irrelevant as sun exposure is not a concern with this medication. Choice D is incorrect as discontinuing the medication without consulting a healthcare provider can lead to adverse effects.
5. What causes type I diabetes?
- A. Overproduction of insulin from the beta cells of the pancreas
- B. Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
- C. Loss of insulin receptors on the target cells, resulting in insulin resistance
- D. A pituitary tumor in the brain, resulting in increased antidiuretic hormone production
Correct answer: B
Rationale: Type I diabetes is caused by the destruction of the beta cells in the pancreas, leading to an inability to produce insulin. This results in a lack of insulin, leading to hyperglycemia. Choice A is incorrect as type I diabetes is characterized by a deficiency of insulin production, not overproduction. Choice C describes the pathophysiology of type 2 diabetes, where insulin receptors become less responsive to insulin. Choice D is unrelated to type I diabetes as it describes a pituitary tumor causing increased antidiuretic hormone production.
