Order: 200 mL normal saline bolus IV over 15 minutes
On hand: 500 mL normal saline bags
What rate will the nurse set the pump to deliver the fluid?
The Correct Answer is ["800"]
This choice is correct because it is the result of dividing the volume of the bolus (200 mL) by the time of the infusion (15 minutes) and multiplying by 60 minutes per hour. The formula for calculating the rate of the pump is:
Rate = (Volume/Time) x 60
Therefore, the rate of the pump is:
Rate = (200 mL/ 15 min) x 60 = 800 mL/hr

Correct Answer is D
Explanation
Choice A reason: This is incorrect because spironolactone does not affect the heart rate. Checking the heart rate before each dose is not necessary.
Choice B reason: This is incorrect because spironolactone does not interact with acetaminophen. Taking acetaminophen with spironolactone will not cause bleeding.
Choice C reason: This is incorrect because spironolactone does not cause dry cough or increase blood sugar. These are not signs of adverse effects of spironolactone.
Choice D reason: This is correct because spironolactone can cause hyperkalemia, which is a high level of potassium in the blood. Bananas, cantaloupe, and spinach are high-potassium foods that should be avoided by clients taking spironolactone.
Correct Answer is ["83"]
Explanation
To calculate the IV flow rate in drops per minute, we can use the following formula:
IV flow rate (gtt/min) = (Volume to be infused in mL drop factor) / Time in minutes
Given:
Volume to be infused = 250 mL
Drop factor = 10 gtt/mL
Time = 30 minutes
Using the formula:
IV flow rate = (250 mL 10 gtt/mL) / 30 min
IV flow rate ≈ (2500 gtt) / 30 min
IV flow rate ≈ 83.33 gtt/min
Rounding to the nearest whole number, the nurse should set the manual IV flow rate to deliver 83 gtt/min.
