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 C
Explanation
The nurse should administer 1 mL per dose to the patient.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
30 mg / 1 mL = 30 mg / x mL
Cross-multiplying and solving for x gives:
x = 1 mL
Therefore, the nurse should administer 1 mL of Toradol injection to deliver 30 mg of the medication to the patient.
Correct Answer is D
Explanation
This numeric form is appropriate, according to the Joint Commission, because it does not use a trailing zero after a decimal point, which is a common cause of medication errors and should be avoided. A trailing zero may be misread or misinterpreted as a larger dose or omited altogether, resulting in a 10-fold overdose or underdose, respectively. For example, when prescriptions have been writen for "Coumadin 1.0 mg," patients have received 10 mg in error¹². Therefore, the Joint Commission requires that a trailing zero may be used only when required to demonstrate the level of precision of the value being reported, such as for laboratory results, imaging studies that report the size of lesions, or catheter/tube sizes. It may not be used in medication orders or other medication-related documentation.
The other options are not appropriate numeric forms because:
a) 3.0 uses a trailing zero after a decimal point, which poses a risk of confusion or error.
b) 0.30 uses a trailing zero after a decimal point, which poses a risk of confusion or error.
c) 0.03 is not equivalent to 0.3, as it is 10 times smaller.
