1. 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?

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.

2. A male patient with erectile dysfunction is prescribed sildenafil (Viagra). What specific instruction should the nurse provide to ensure the safe use of this medication?

Correct answer: B

Rationale: The correct instruction the nurse should provide is to avoid taking nitrates while on sildenafil (Viagra). Combining sildenafil with nitrates can result in severe hypotension due to additive vasodilatory effects. Choice A is incorrect because sildenafil can be taken with or without food. Choice C is incorrect as there is no specific requirement to take sildenafil at bedtime. Choice D is incorrect as taking sildenafil with milk has not been shown to enhance its absorption.

3. How will taking an oral contraceptive affect the physiologically of an insulin-dependent diabetic patient?

Correct answer: C

Rationale: Taking an oral contraceptive can lead to an increase in blood glucose levels in insulin-dependent diabetic patients. This occurs due to the hormonal changes induced by the contraceptive, which can impact insulin sensitivity. Therefore, diabetic patients need to closely monitor their blood glucose levels when starting an oral contraceptive to prevent complications. The other choices are incorrect as oral contraceptives do not typically lead to an increase in heart rate, risk of hypoglycemia, or risk of metabolic alkalosis in this context.

4. What is the pathophysiologic process responsible for the decreased glomerular filtration rate in a patient with acute glomerulonephritis?

Correct answer: B

Rationale: The correct answer is B: Immune complex deposition, increased capillary permeability, and cellular proliferation. Acute glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys. This inflammation leads to the deposition of immune complexes, increased capillary permeability, and cellular proliferation, which collectively contribute to a decreased glomerular filtration rate. Choice A is incorrect as decreased renal-induced constriction of the renal arteries would not directly result in decreased glomerular filtration rate. Choice C is incorrect as necrosis of nephrons due to increased kidney interstitial hydrostatic pressure would affect kidney function differently. Choice D is incorrect as scar tissue formation in the proximal convoluted tubule due to toxin-induced collagen synthesis is not a typical feature of acute glomerulonephritis.

5. What is reperfusion injury?

Correct answer: C

Rationale: Reperfusion injury refers to the secondary injury that occurs after blood flow is reestablished following ischemia. This process leads to tissue damage due to the sudden reintroduction of oxygen and nutrients, causing oxidative stress, inflammation, and cell death. Choice A is incorrect as it describes the normal healing process of bone tissue after a fracture. Choice B is incorrect as it describes specific mechanisms related to skin wounds, not reperfusion injury. Choice D is incorrect as it refers to a different concept, which is adverse reactions or complications that can occur after a blood transfusion, not reperfusion injury.
