Correct Answer is ["31"]

Explanation

Step 1: Calculate the total volume to be infused. Total volume = 250 mL.

Step 2: Calculate the total time for the infusion in minutes. Total time = 2 hours × 60 minutes/hour = 120 minutes.

Step 3: Calculate the flow rate in mL/min. Flow rate = Total volume ÷ Total time = 250 mL ÷ 120 min = 2.08 mL/min.

Step 4: Calculate the flow rate in drops/min. Flow rate = 2.08 mL/min × 15 drops/mL = 31.25 drops/min. So, the nurse should adjust the flow rate to deliver approximately 31 drops per minute.

A. Purulent. B. Sanguineous. C. Serosanguineous. D. Serous.

Correct Answer is C

Explanation

Choice A rationale

Purulent drainage is thick and opaque. It can have a yellow, tan, green, or brown color and is a sign of infection.

Choice B rationale

Sanguineous drainage is bright red and indicates active bleeding3.

Choice C rationale

Serosanguineous drainage is typically pink-red and thin. It is made up of blood and serous fluid and is typically seen in a normal, non-infected wound3.
