1. What are the major mechanisms of spinal cord injuries?

• A. Hypoextension, expansion, hyperflexion
• B. Hyperflexion, expansion, hypometabolism
• C. Hypermetabolism, compression, hyperextension
• D. Hyperextension, hyperflexion, compression

Correct answer: D

Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.

2. A 75-year-old male presents with chest pain on exertion. The chest pain is most likely due to hypoxic injury secondary to:

• A. Malnutrition
• B. Free radicals
• C. Ischemia
• D. Chemical toxicity

Correct answer: C

Rationale: The correct answer is C: Ischemia. In this scenario, the 75-year-old male experiences chest pain on exertion, which is indicative of angina. Angina is primarily caused by reduced blood flow to the heart muscle, leading to hypoxic injury. This condition is known as ischemia. Options A, B, and D are incorrect. Malnutrition does not typically cause chest pain related to exertion. Free radicals and chemical toxicity are not common causes of chest pain in the context described. Therefore, the most likely cause of chest pain in this case is ischemia due to reduced blood flow.

3. A patient is starting on medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse include in the patient teaching?

• A. Take the medication with food to prevent nausea.
• B. Take the medication at the same time each day to maintain consistent hormone levels.
• C. Avoid prolonged sun exposure while taking this medication.
• D. Discontinue the medication if side effects occur.

Correct answer: B

Rationale: The correct answer is B. Patients starting on medroxyprogesterone acetate (Provera) for endometriosis should be instructed to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Choice A is incorrect because medroxyprogesterone acetate can be taken with or without food. Choice C is unrelated to the medication and not a specific concern with its use. Choice D is incorrect as patients should not discontinue the medication without consulting their healthcare provider, even if side effects occur.

4. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What should the nurse include in the patient education?

• A. The medication is expected to reduce the size of the prostate, which should improve urinary symptoms over time.
• B. The medication will improve symptoms within a few days.
• C. The medication will cure BPH after treatment is complete.
• D. The medication may cause erectile dysfunction as a side effect.

Correct answer: A

Rationale: Finasteride is expected to reduce the size of the prostate, which should improve urinary symptoms over time, although the effects may take several weeks or months to become noticeable.

5. A nurse is teaching a patient about the use of raloxifene (Evista) for the prevention of osteoporosis. What is the primary therapeutic action of this medication?

• A. It decreases the absorption of calcium from the intestines.
• B. It decreases bone resorption and increases bone density.
• C. It increases the excretion of calcium through the kidneys.
• D. It stimulates the formation of new bone.

Correct answer: B

Rationale: The correct answer is B. Raloxifene, a selective estrogen receptor modulator (SERM), works by decreasing bone resorption and increasing bone density. This action helps in preventing osteoporosis by maintaining bone strength. Choice A is incorrect as raloxifene does not affect the absorption of calcium from the intestines. Choice C is incorrect as raloxifene does not increase the excretion of calcium through the kidneys. Choice D is incorrect as raloxifene does not directly stimulate the formation of new bone; instead, it primarily works by reducing bone loss.
