Nursing Elites

1. Which of the following conditions is associated with a positive Homan's sign?

• A. Deep vein thrombosis
• B. Peripheral artery disease
• C. Varicose veins
• D. Lymphedema

Correct answer: A

Rationale: A positive Homan's sign is indicative of deep vein thrombosis. This sign is elicited by dorsiflexing the foot of a patient with the knee slightly flexed, resulting in calf pain. Peripheral artery disease (choice B) is associated with decreased blood flow to the extremities, but it does not produce a positive Homan's sign. Varicose veins (choice C) are enlarged, twisted veins that are typically not related to Homan's sign. Lymphedema (choice D) is swelling caused by a lymphatic system blockage or dysfunction and is not linked to Homan's sign.

2. During a late-night study session, a pathophysiology student reaches out to turn the page of her textbook. Which component of her nervous system contains the highest level of control of her arm and hand action?

• A. Cerebral cortex
• B. Basal ganglia
• C. Brainstem
• D. Cerebellum

Correct answer: A

Rationale: The correct answer is A: Cerebral cortex. The cerebral cortex, particularly the motor cortex, is responsible for the voluntary control of precise movements such as turning a page. The cerebral cortex plays a crucial role in the highest level of control of motor functions, including those of the arm and hand. Choice B, Basal ganglia, is more involved in motor planning and coordination, while choice C, Brainstem, is responsible for basic life functions and reflexes. Choice D, Cerebellum, is primarily involved in coordination, precision, and accurate timing of movements, rather than the highest level of control for specific actions like page-turning.

3. In which of the following cases is dehydration more likely to occur?

• A. A 50-year-old woman who is a bodybuilder
• B. A 50-year-old man who is morbidly obese
• C. A 10-year-old child who is thin
• D. A 30-year-old with multiple sclerosis

Correct answer: B

Rationale: The correct answer is B. Morbid obesity increases the risk of dehydration due to the larger body surface area and potential for greater insensible losses. Choices A, C, and D are less likely to experience dehydration compared to a morbidly obese individual.

4. A client with a history of hypertension presents with a severe headache and blurred vision. What is the nurse's priority action?

• A. Administer pain relief medication.
• B. Obtain a stat head CT scan.
• C. Administer antihypertensive medications as prescribed.
• D. Call the healthcare provider immediately.

Correct answer: C

Rationale: The correct answer is to administer antihypertensive medications as prescribed. In a client with a history of hypertension presenting with severe headache and blurred vision, these symptoms could indicate a hypertensive crisis. The priority action is to lower the blood pressure promptly to prevent complications such as stroke, heart attack, or organ damage. Administering antihypertensive medications is crucial in this situation. Administering pain relief medication (Choice A) may temporarily alleviate symptoms but does not address the underlying issue of elevated blood pressure. Obtaining a stat head CT scan (Choice B) may be necessary to rule out other causes but should not delay the administration of antihypertensive medications. Calling the healthcare provider immediately (Choice D) is important but may not address the immediate need to lower blood pressure in a hypertensive crisis.

5. A patient is prescribed finasteride (Proscar) for benign prostatic hyperplasia (BPH). What outcome should the nurse expect to observe?

• A. Decreased urinary frequency and urgency
• B. Increased prostate size
• C. Increased blood pressure
• D. Increased risk of kidney stones

Correct answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is expected to decrease urinary frequency and urgency in patients with BPH by reducing prostate size. It works by inhibiting the enzyme that converts testosterone to dihydrotestosterone, which helps shrink the prostate gland. Choices B, C, and D are incorrect. Finasteride does not increase prostate size, blood pressure, or the risk of kidney stones.
