Nursing Elites

1. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.

2. In which situation is it most important for the registered nurse (RN) working on a medical unit to provide direct supervision?

• A. A graduate nurse needs to access a client's implanted port to start an infusion of Ringer's Lactate.
• B. A postpartum nurse pulled to the unit needs to start a transfusion of packed red blood cells.
• C. A practical nurse is preparing to assist the healthcare provider with a lumbar puncture at the bedside.
• D. An unlicensed assistive personnel is preparing to weigh an obese bedfast client using a bed scale.

Correct answer: A

Rationale: Direct supervision is essential when a complex task, such as accessing an implanted port, is being performed by a less experienced healthcare provider, in this case, a graduate nurse. This oversight ensures patient safety and proper execution of the procedure, especially when it is the nurse's first time performing such a task.

3. In a client with liver cirrhosis experiencing confusion and disorientation, what condition is most likely causing these symptoms?

• A. Hepatic encephalopathy
• B. Hypoglycemia
• C. Electrolyte imbalance
• D. Dehydration

Correct answer: A

Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness. Hypoglycemia (choice B) may present with confusion but is less likely in a client with liver cirrhosis without a history of diabetes or insulin use. Electrolyte imbalance (choice C) and dehydration (choice D) can contribute to confusion but are not the primary causes in a client with liver cirrhosis experiencing these symptoms.

4. The client with chronic kidney disease (CKD) is receiving hemodialysis. Which finding should be reported to the healthcare provider immediately?

• A. Blood pressure of 150/90 mm Hg.
• B. Weight gain of 2 pounds since the last dialysis session.
• C. Blood glucose level of 120 mg/dl.
• D. Potassium level of 6.5 mEq/L.

Correct answer: D

Rationale: A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, which can lead to severe cardiac complications like arrhythmias and cardiac arrest. Immediate medical intervention is necessary to lower potassium levels to prevent life-threatening outcomes in clients undergoing hemodialysis.

5. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

• A. Serum sodium.
• B. Serum potassium.
• C. Serum calcium.
• D. Serum magnesium.

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.
