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?
41.6 gt/min
0.2 gt/min
2.7 gt/min
24 gt/min
The Correct Answer is A
To calculate the gt/min flow rate, we need to determine the total number of drops and divide it by the total time in minutes.
First, let's convert the volume from liters to milliliters:
1 L = 1000 mL
Next, we need to determine the total number of drops. This can be calculated using the drop factor and the volume of the solution:
Total drops = Volume (mL) * Drop factor
= 1000 mL * 15 gt/mL
= 15000 gt
Now, we need to calculate the flow rate in gt/min. We divide the total drops by the total time in minutes: Flow rate = Total drops / Total time (min)
= 15000 gt / 360 min
≈ 41.67 gt/min (rounded to the nearest whole number)
Therefore, the correct answer is:
a. 41.6 gt/min

Correct Answer is D
Explanation
To answer this question, we need to calculate the infusion rate in mL per hour by using the following formula²:
Infusion rate (mL/h) = Dose (mcg/kg/min) × Weight (kg) × 60 min/h × Volume (mL) / Concentration (mcg/mL)
In this case, the infusion rate is:
Infusion rate (mL/h) = 3 mcg/kg/min × 70 kg × 60 min/h × 250 mL / 2500 mg
We need to convert lb to kg by dividing by 2.2
Infusion rate (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / 2500 mg
We need to convert mg to mcg by multiplying by 1000:
Infusion rte (mL/h) = 3 mcg/kg/min × (154 lb / 2.2 kg/lb) × 60 min/h × 250 mL / (2500 mg × 1000 mcg/mg)
We can simplify the equation by canceling out some units and numbers:
Infusion rate (mL/h) = 3 × 154 × 250 / (2.2 × 2500 × 1000)
We can use a calculator to get the final answer:
Infusion rate (mL/h) = 12.6363636363636 mL/h
Correct Answer is C
Explanation
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
