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. What instruction should the nurse give regarding the administration of alendronate to a patient with osteoporosis?

• A. Take the medication with milk.
• B. Lie down for 30 minutes after taking the medication.
• C. Take the medication with a full glass of water.
• D. Take the medication before bedtime.

Correct answer: C

Rationale: The correct instruction for administering alendronate to a patient with osteoporosis is to take the medication with a full glass of water first thing in the morning. It is important for the patient to remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation. Taking alendronate with milk, lying down after intake, or taking it before bedtime can reduce the medication's effectiveness or increase the risk of side effects.

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. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

5. A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?

• A. Administer regular insulin intravenously.
• B. Give oral hypoglycemic agents.
• C. Administer sodium bicarbonate.
• D. Provide a high-calorie diet.

Correct answer: A

Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Administering oral hypoglycemic agents is not appropriate in the acute setting of DKA as they may not work quickly enough compared to intravenous insulin. While sodium bicarbonate may be used to correct acidosis, insulin administration is the priority to address both hyperglycemia and acidosis simultaneously. Providing a high-calorie diet is not suitable initially in DKA management; the main focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.
