A nurse is preparing to administer 1 L of 0.9% sodium chloride solution to a client over 6 hours. The intravenous (IV) fluid has a drop factor of 15 gt/mL. What will be the gt/min flow rate?

To answer this question, the nurse needs to perform the following steps:

1) Convert the patient's weight from pounds and ounces to kilograms, using the conversion factor of 1 pound = 0.45359237 kilograms¹². To do this, first convert the ounces to a fraction of a pound by dividing by 16, then add this fraction to the pounds, and then multiply by the conversion factor. For example:

7 lb, 11.2 oz = 7 + (11.2 / 16) lb
= 7.7 lb
= 7.7 × 0.45359237 kg
= 3.492 kg

2) Calculate the dose of Garamycin in milligrams, using the prescribed dose of 4 mg/kg and the patient's weight in kilograms. To do this, simply multiply the dose per kilogram by the weight in kilograms. For example:

4 mg/kg × 3.492 kg = 13.968 mg

3) Calculate the volume of Garamycin in milliliters, using the reconstituted dosage of 20 mg/10 mL and the dose in milligrams. To do this, use a proportion to find the unknown volume that corresponds to the known dose. For example:

20 mg / 10 mL = 13.968 mg / x mL Cross-multiply and solve for x: 20x = 139.68

x = 6.984 mL
x =7 mL

The infusion will be completed at 3:15 p.m.

This answer is correct because it is based on a simple division and addition calculation. The nurse should follow these steps to determine when the infusion will be completed:

1) Convert the volume of the fluid from liters to milliliters by multiplying by 1000, since there are 1000 mL in 1 L. The volume of the fluid is 750 mL.

2) Divide the volume of the fluid by the infusion rate to get the duration of the infusion in hours, as follows:

750 mL / 120 mL/hr = 6.25 hr

Therefore, the infusion will take 6.25 hours to complete.

3) Add the duration of the infusion to the start time of the infusion to get the end time, as follows:

9:00 a.m. + 6:25 = 3:15 p.m.

Therefore, the infusion will be completed at 3:15 p.m.
