A nurse is preparing to administer 0.9% sodium chloride (NS) 100 mL IV to infuse over 4 hr. The drip factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
(Round the answer to the nearest whole number.)
Answer and Explanation

The Correct Answer is ["25"]

To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given: 

Volume to be infused: 100 ml 

Drop factor: 60 gtt/ml 

Time: 4 hr 

First, we need to convert the time from hours to minutes: 

4 hr * 60 min/hr = 240 min 

Now, we can calculate the infusion rate: 

Infusion rate (gtt/min) = (100 ml * 60 gtt/ml) / 240 min 

Simplifying the equation: 

Infusion rate (gtt/min) = 6000 gtt / 240 min 

Dividing both sides: 

Infusion rate (gtt/min) ≈ 25 gtt/min

Correct Answer is B

Explanation

A. "I feel so much better after eating."This is most consistent with a duodenal ulcer, where pain is relieved by food (but often returns 2–3 hours later). Gastric ulcers, on the other hand, may worsen with eating.

B. "The pain is worse after I eat a meal high in fat."Fatty food intolerance and postprandial pain are more characteristic of gallbladder disease (cholelithiasis/cholecystitis), not PUD.

C. "The pain radiates down to my lower back."Pain radiating to the back is more typical of pancreatitis, not PUD.

D. "My pain is relieved by having a bowel movement."Relief of abdominal pain with a bowel movement suggests irritable bowel syndrome (IBS), not PUD.

Correct Answer is ["14"]

Explanation

To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:

Volume to be infused: 1000 ml

Drop factor: 10 gtt/ml

Time: 12 hr

First, we need to convert the time from hours to minutes:

12 hr * 60 min/hr = 720 min

Now, we can calculate the infusion rate:

Infusion rate (gtt/min) = (1000 ml * 10 gtt/ml) / 720 min

Simplifying the equation:

Infusion rate (gtt/min) = 10000 gtt / 720 min

Dividing both sides:

Infusion rate (gtt/min) ≈ 13.89 gtt/min

Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 14 gtt/min.
