A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion.

Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag.

The client weighs 80 kg. The nurse should set the IV infusion to deliver how many mL/hr? (Round the answer to the nearest whole number.

Use a leading zero if it applies.)

4 mL/hr.

5 mL/hr.

6 mL/hr.

7 mL/hr.

Answer and Explanation

The Correct Answer is C

Step 1: Convert the dopamine hydrochloride dose from mcg to mg. We know that 1 mg = 1000 mcg. So, 4 mcg = 0.004 mg.

Step 2: Calculate the total amount of dopamine hydrochloride the client needs per minute. We know that the client weighs 80 kg and the dose is 0.004 mg/kg/min. So, 0.004 mg/kg/min × 80 kg = 0.32 mg/min.

Step 3: Convert the total amount of dopamine hydrochloride the client needs per minute to an hourly rate. We know that 1 hour = 60 minutes. So, 0.32 mg/min × 60 min/hr = 19.2 mg/hr.

Step 4: Calculate the volume of the solution that contains 19.2 mg of dopamine hydrochloride. We know that the solution contains 800 mg in 250 mL. So, (19.2 mg ÷ 800 mg) × 250 mL = 6 mL.

Therefore, the nurse should set the IV infusion to deliver 6 mL/hr (rounded to the nearest whole number).

Correct Answer is B

Explanation

Choice A rationale:

Wearing clothing with zippers instead of buttons does not address the safety concerns related to Alzheimer's disease. This choice does not ensure the client's safety or prevent wandering, which are common issues in Alzheimer's patients.

Choice B rationale:

Placing locks at the tops of exterior doors is essential for the safety of clients with Alzheimer's disease. Alzheimer's patients often have a tendency to wander and may become disoriented, putting them at risk of getting lost or injured outside the home. Proper locks can prevent them from leaving the house unsupervised.

Choice C rationale:

Replacing the carpet with hardwood floors may reduce the risk of falls but does not specifically address the safety concerns related to Alzheimer's disease. It is important to focus on measures that prevent wandering and ensure the client's safety in various situations.

Choice D rationale:

Encouraging physical activity prior to bedtime is a good practice for promoting sleep in older adults but does not directly address the safety concerns of Alzheimer's patients. Safety measures, such as securing doors, supervising the client, and preventing wandering, are more crucial in this context.

A. Maintain bed elevation at 20 degrees. B. Flush the tubing with 30 mL of water every 4 hr. C. Check for gastric residual every 12 hr. D. Place enough formula in the container to last 18 hr.

Correct Answer is B

Explanation

The correct answer is Choice B.

Choice A rationale: Maintaining bed elevation at 20 degrees is not recommended. The recommended bed elevation for patients receiving enteral tube feedings is at least 30 to 45 degrees.This is to prevent aspiration of the feeding solution into the lungs.

Choice B rationale: Flushing the tubing with 30 mL of water every 4 hours is a recommended practice.This helps to maintain the patency of the feeding tube and prevent clogging.

Choice C rationale: Checking for gastric residual every 12 hours is not sufficient.For patients receiving continuous tube feedings, gastric residual volume (GRV) should be monitored every 4 hours.This helps to assess tolerance to the feeding and prevent complications such as aspiration.

Choice D rationale: Placing enough formula in the container to last 18 hours is not recommended.For an open system, the formula should be replaced every 4 hours to prevent bacterial growth.
