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 with diabetes mellitus is being taught by a nurse on managing hypoglycemia. Which of the following instructions should the nurse include?

• A. Avoid consuming carbohydrate-rich foods.
• B. Consume 15 grams of a fast-acting carbohydrate.
• C. Drink a glass of water to raise blood glucose levels.
• D. Eat a snack before exercising to prevent hypoglycemia.

Correct answer: B

Rationale: The correct answer is B: Consume 15 grams of a fast-acting carbohydrate. Consuming 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, helps raise blood glucose levels quickly in cases of hypoglycemia. Choice A is incorrect because avoiding carbohydrate-rich foods during hypoglycemia can worsen the condition. Choice C is incorrect as drinking water does not effectively raise blood glucose levels. Choice D is incorrect as eating a snack before exercising is more related to preventing exercise-induced hypoglycemia, not managing hypoglycemia.

3. A nurse is providing discharge teaching to a client who has a new diagnosis of diabetes mellitus. Which of the following client statements indicates a need for further teaching?

• A. I will check my blood glucose level once a week.
• B. I will eat a snack if my blood glucose level is above 200 mg/dL.
• C. I will take my insulin as prescribed, even when I am feeling well.
• D. I will avoid physical activity if my blood glucose level is below 100 mg/dL.

Correct answer: B

Rationale: The correct answer is B. Clients should eat a snack when their blood glucose level is low, typically below 70-100 mg/dL, not when it is high. Eating a snack when the blood glucose level is above 200 mg/dL can exacerbate hyperglycemia. Choice A is correct as checking blood glucose levels regularly is important in managing diabetes. Choice C is also correct as adherence to prescribed insulin therapy is crucial. Choice D is incorrect as physical activity can help lower blood glucose levels, especially when they are above the target range.

4. A client is 2 hours postoperative following a total knee arthroplasty. Which of the following findings should the nurse report to the provider?

• A. Heart rate 88/min
• B. Capillary refill of 2 seconds
• C. Pain level of 8 on a scale of 0 to 10
• D. Temperature of 37.8°C (100°F)

Correct answer: C

Rationale: A pain level of 8 is high and may indicate inadequate pain control or complications following surgery. Monitoring and managing pain is crucial postoperatively to ensure patient comfort and prevent complications. A heart rate of 88/min, capillary refill of 2 seconds, and a temperature of 37.8°C (100°F) are within normal ranges and do not typically require immediate reporting unless in the context of other concerning signs or symptoms.

5. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Take the medication with food to prevent stomach upset.
• C. Take one tablet every 5 minutes, up to three doses, for chest pain.
• D. Swallow the tablet whole for the best effect.

Correct answer: C

Rationale: The correct instruction for a client with a new prescription for nitroglycerin sublingual tablets is to take one tablet every 5 minutes, up to three doses, for chest pain. This dosing regimen helps relieve chest pain associated with angina by promoting vasodilation. Option A is incorrect as nitroglycerin sublingual tablets should be placed under the tongue, not swallowed with water. Option B is incorrect because taking nitroglycerin with food may decrease its effectiveness. Option D is incorrect because nitroglycerin sublingual tablets are meant to be dissolved under the tongue, not swallowed whole.
