Nursing Elites

1. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

2. A male client with hypertension, who received new antihypertensive prescriptions at his last visit returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him feel bad. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?

• A. Stroke secondary to hemorrhage
• B. Myocardial infarction
• C. Heart failure
• D. Renal failure

Correct answer: A

Rationale: Stroke is a major complication of uncontrolled hypertension. Elevated BP, especially at levels like 158/106, can cause damage to blood vessels in the brain, leading to a hemorrhagic stroke. Controlling BP is essential to prevent such life-threatening events. Myocardial infarction (choice B) is more commonly associated with coronary artery disease, while heart failure (choice C) and renal failure (choice D) can be complications of uncontrolled hypertension but are not directly related to the elevated BP leading to a hemorrhagic stroke.

3. A client with heart failure is prescribed furosemide. The nurse notes that the client's potassium level is 3.1 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement
• B. Encourage the client to eat potassium-rich foods
• C. Hold the next dose of furosemide
• D. Increase the client's fluid intake

Correct answer: A

Rationale: A potassium level of 3.1 mEq/L is considered low, indicating hypokalemia. Administering a potassium supplement is the nurse's priority action to prevent complications such as cardiac arrhythmias associated with low potassium levels. Encouraging the client to eat potassium-rich foods is beneficial in the long term but may not rapidly correct the low potassium level. Holding the next dose of furosemide may worsen the client's heart failure symptoms. Increasing the client's fluid intake is not the priority action in this situation; addressing the low potassium level takes precedence to prevent potential serious complications.

4. Which information is a priority for the RN to reinforce to an older client after intravenous pyelography?

• A. Eat a light diet for the remainder of the day
• B. Rest for the next 24 hours as the preparation and the test are tiring
• C. Drink at least 1 8-ounce glass of fluid every waking hour for the next 2 days
• D. Measure the urine output for the next day and promptly notify the healthcare provider if it decreases

Correct answer: D

Rationale: After intravenous pyelography, it is crucial for the client to measure urine output in the next day to monitor for any potential complications, such as kidney issues. Promptly notifying the healthcare provider in case of decreased urine output is essential for timely intervention. While rest and hydration are important post-procedure, monitoring urine output takes precedence due to its direct correlation with potential complications.

5. An older client with type 1 diabetes arrives at the clinic with abdominal cramping, vomiting, lethargy, and confusion. What should the nurse implement first?

• A. Start an IV infusion of normal saline.
• B. Obtain a serum potassium level.
• C. Administer the client's usual dose of insulin.
• D. Assess the pupillary response to light.

Correct answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.
