Nursing Elites

1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

2. A client who is receiving continuous enteral feedings through a nasogastric tube needs preventive measures to avoid aspiration. Which of the following actions should the nurse take?

• A. Elevate the head of the bed to 30 degrees.
• B. Check gastric residual volumes every 4 hours.
• C. Administer the feeding at room temperature.
• D. Flush the feeding tube with 20 mL of water every 8 hours.

Correct answer: B

Rationale: The correct answer is to check gastric residual volumes every 4 hours. This action helps prevent aspiration by ensuring the stomach is emptying properly, reducing the risk of reflux and aspiration. Elevating the head of the bed to 30 degrees can help prevent aspiration by promoting proper digestion and reducing the risk of regurgitation. Administering the feeding at room temperature is important for patient comfort but does not directly prevent aspiration. Flushing the feeding tube with water every 8 hours is important for tube patency but does not directly prevent aspiration.

3. A healthcare professional is assessing a client who has chronic kidney disease. Which of the following findings should the healthcare professional report to the provider?

• A. Urine output of 80 mL/hr
• B. Blood pressure of 140/90 mm Hg
• C. Serum creatinine 2.8 mg/dL
• D. Heart rate of 72/min

Correct answer: C

Rationale: The correct answer is C. A serum creatinine level of 2.8 mg/dL indicates impaired kidney function and should be reported to the healthcare provider. Elevated serum creatinine levels are indicative of decreased kidney function and potential progression of chronic kidney disease. Choices A, B, and D are within normal ranges and do not signify immediate concerns related to kidney disease. Urine output of 80 mL/hr is appropriate, a blood pressure of 140/90 mm Hg is considered prehypertensive but not acutely concerning, and a heart rate of 72/min falls within the normal range.

4. A nurse is preparing to administer digoxin to a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Heart rate of 60/min
• D. Sodium 140 mEq/L

Correct answer: C

Rationale: The correct answer is C: Heart rate of 60/min. A heart rate of 60/min is borderline bradycardia, which can be a sign of digoxin toxicity. Digoxin can cause bradycardia, so any further decrease in heart rate should be reported promptly to the healthcare provider. Choices A, B, and D are within the normal range and not specifically related to potential digoxin toxicity, so they do not require immediate reporting.

5. A client with diabetes mellitus is receiving discharge instructions from a nurse. Which statement by the client indicates an understanding of the teaching?

• A. I will monitor my blood sugar level once a week.
• B. I will exercise every day even if my blood sugar is low.
• C. I will eat snacks rich in carbohydrates if my blood sugar drops.
• D. I will avoid sugary foods to prevent my blood sugar from rising.

Correct answer: C

Rationale: The correct answer is C. Eating snacks rich in carbohydrates is essential to manage hypoglycemia by raising blood sugar levels. Option A is incorrect as monitoring blood sugar once a week is not frequent enough for effective diabetes management. Option B is incorrect because exercising when blood sugar is low can worsen hypoglycemia. Option D is incorrect as it focuses on preventing high blood sugar levels, not managing low blood sugar.
