1. A client reports dizziness when standing up quickly. What advice should the nurse give?

• A. Encourage the client to drink more fluids.
• B. Change positions slowly to prevent dizziness.
• C. Report the symptom to the healthcare provider immediately.
• D. Limit physical activity to avoid triggering dizziness.

Correct answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.

2. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication ____________.

• A. Can predispose to dysrhythmias
• B. May lead to oliguria
• C. May cause irritability and anxiety
• D. Sometimes alters consciousness

Correct answer: A

Rationale: The correct answer is A: Can predispose to dysrhythmias. Hypokalemia combined with digoxin increases the risk of dysrhythmias due to the potentiation of digoxin's effects on cardiac conduction. Choice B, May lead to oliguria, is incorrect because hypokalemia is not typically associated with oliguria. Choice C, May cause irritability and anxiety, is incorrect as these symptoms are more commonly associated with hypocalcemia. Choice D, Sometimes alters consciousness, is incorrect as altered consciousness is not a typical effect of hypokalemia combined with digoxin.

3. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

4. To auscultate for a carotid bruit, where should the nurse place the stethoscope?

• A. Base of the neck on the right side
• B. Above the clavicle
• C. Over the sternum
• D. Over the trachea

Correct answer: A

Rationale: To auscultate for a carotid bruit, the nurse should place the stethoscope at the base of the neck, near the carotid artery. A carotid bruit is an abnormal sound that indicates turbulent blood flow in the carotid artery, potentially due to arterial narrowing or atherosclerosis. Placing the stethoscope above the clavicle, over the sternum, or over the trachea would not provide the nurse with the optimal location to assess for carotid artery abnormalities.

5. An older client with a long history of coronary artery disease, HTN, and HF arrives in the ED in respiratory distress. The healthcare provider prescribes furosemide IV. Which therapeutic response to furosemide should the nurse expect in the client with acute HF?

• A. Decreased heart rate
• B. Improved blood pressure
• C. Increased urine output
• D. Reduced preload

Correct answer: D

Rationale: The correct answer is D: Reduced preload. Furosemide is a diuretic that reduces fluid overload in heart failure, which lowers the preload (the volume of blood in the ventricles before contraction). By reducing this volume, furosemide improves symptoms of heart failure. While furosemide may lead to increased urine output and lower blood pressure, these effects are secondary to the reduction in preload. Decreased heart rate is not a direct effect of furosemide in heart failure.
