A client receives a prescription for dextrose 5% in water 500 mL IV to
be infused over 4 hours. The IV-administration set delivers 15 gtt/mL.
How many gtt/min should the nurse regulate the infusion? (Enter
numerical value only. If rounding is required, round to the nearest
whole number.)

To find out how many gtt/min the nurse should regulate the infusion;
We can use the following formula:
Flow rate (gtt/min) = Total volume (mL) / Time (min) × Drop factor (gtt/mL)
Given:
Total volume = 500 mL
Time = 4 hours = 240 minutes (since 1 hour = 60 minutes)
Drop factor = 15 gtt/mL
Substituting the given values into the formula:
Flow rate (gtt/min) =500 mL/240 min ×15 gtt/mL
After performing the calculation, we find that the flow rate equals 31.25
gtt/min.
So, the nurse should regulate the infusion to 31 gtt/min (rounded to the
nearest whole number)

Calculations:
Desired dose: 1.2 million units
Available dose: 600,000 units/2 mL
To find the volume to administer, we can use the following formula:
Volume to administer = (Desired dose / Available dose) * Volume per dose
Volume to administer = (1,200,000 units / 600,000 units/mL) * 2 mL = 4 mL
Therefore, the nurse should administer 4 mL of the penicillin solution.

To find out how many mL the nurse should administer:
We can set up a proportion to solve for the unknown.
Given:
The prescription is for 1,000,000 units of penicillin G.
The available medication is 1,200,000 units/2 mL.
We can set up the proportion as follows:
1,000,000 units/ x mL = 1,200,000 units/2 mL
Solving for x gives us the volume in mL that the nurse should administer.
Cross-multiplying and solving for x:
X = 1,000,000 units×2 mL/1,200,000 units
After performing the calculation, we find that x equals 1.67 mL.
, So, the nurse should administer 1.7 mL (rounded to the nearest tenth) of the
medication.
