A nurse is preparing to administer an IV fluid bolus of 500 mL 0.9% sodium chloride over 60 min. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading if it applies. Do not use a trailing zero.)
The Correct Answer is ["83"]
Given:
Total volume to infuse: 500 mL
Infusion time: 60 minutes
Drop factor of tubing: 10 gtt/mL
To find:
Drip rate (gtt/min)
Step 1: Calculate the total number of drops
Total drops = Total volume x Drop factor
Total drops = 500 mL x 10 gtt/mL = 5000 gtt
Step 2: Calculate the drip rate
Drip rate = Total drops / Infusion time in minutes
Drip rate = 5000 gtt / 60 minutes = 83.33 gtt/min
Step 3: Round to the nearest whole number
83 gtt/min

Correct Answer is ["2"]
Explanation
Given:
Desired dose: Digoxin 0.25 mg PO daily
Available concentration: Digoxin 0.125 mg tablets
To find:
Number of tablets to administer
Step 1: Calculate the number of tablets
Divide the desired dose by the strength of each tablet:
Number of tablets = Desired dose / Tablet strength
Number of tablets = 0.25 mg / 0.125 mg/tablet = 2 tablets
Correct Answer is ["5"]
Explanation
Given:
Desired dose: Metoprolol 5 mg IV bolus
Available concentration: Metoprolol injection 1 mg/mL
To find:
Volume to administer per dose (in mL)
Step 1: Set up the proportion
(Desired dose) / (Available concentration) = Volume to administer
Step 2: Substitute the values
Plugging in the given values, we get:
(5 mg) / (1 mg/mL) = Volume to administer
Step 3: Simplify
To simplify, we can invert the denominator and multiply:
(5 mg) x (1 mL / 1 mg) = Volume to administer
The "mg" units cancel out, leaving us with:
(5 x 1 mL) / 1 = Volume to administer
Step 4: Calculate
Performing the multiplication and division, we get:
5 mL / 1 = Volume to administer
5 mL = Volume to administer
