Nursing Elites

1. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?

• A. Bounding erratic pulse.
• B. Regularly irregular pulse.
• C. Thready irregular pulse.
• D. No palpable pulse.

Correct answer: D

Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.

2. A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?

• A. With meals
• B. At bedtime
• C. Before meals
• D. After meals

Correct answer: C

Rationale: Omeprazole is best taken before meals for optimal effectiveness in reducing stomach acid production and promoting ulcer healing. Taking it before meals allows the medication to act on the proton pumps before food intake triggers acid production, thereby maximizing its therapeutic benefits. Choices A, B, and D are incorrect because taking omeprazole with meals, at bedtime, or after meals may not align with its mechanism of action, potentially reducing its effectiveness in managing peptic ulcer disease.

3. When assessing a client reporting severe pain in the right lower quadrant of the abdomen, which sign would most likely indicate appendicitis?

• A. Rebound tenderness at McBurney's point.
• B. Positive Murphy's sign.
• C. Rovsing's sign.
• D. Cullen's sign.

Correct answer: A

Rationale: Rebound tenderness at McBurney's point is a classic sign of appendicitis. This sign indicates peritoneal irritation, a common feature of appendicitis. McBurney's point is located in the right lower quadrant of the abdomen and is a focal point for assessing tenderness. Positive Murphy's sign is associated with cholecystitis, not appendicitis. Rovsing's sign is elicited by palpation of the left lower quadrant resulting in pain in the right lower quadrant, also suggestive of appendicitis. Cullen's sign is associated with acute pancreatitis and manifests as periumbilical ecchymosis.

4. The client has been prescribed metformin (Glucophage) for type 2 diabetes. Which instruction should the nurse include in discharge teaching?

• A. Take the medication at bedtime.
• B. Take the medication with meals.
• C. Take the medication on an empty stomach.
• D. Take the medication as needed for high blood sugar.

Correct answer: B

Rationale: The correct instruction for taking metformin (Glucophage) is with meals. This helps reduce gastrointestinal side effects and improves the medication's absorption. Taking it on an empty stomach can lead to more adverse effects, so it is essential to take it with food. Option A ('Take the medication at bedtime') is incorrect because metformin should be taken with meals to enhance its effectiveness and reduce side effects. Option C ('Take the medication on an empty stomach') is incorrect as taking metformin on an empty stomach can increase the likelihood of experiencing gastrointestinal issues. Option D ('Take the medication as needed for high blood sugar') is incorrect because metformin is typically taken regularly as prescribed, not just as needed for high blood sugar.

5. Why is a low-protein diet recommended for a client with hepatic encephalopathy?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Increased ammonia levels
• D. Electrolyte imbalance

Correct answer: C

Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.
