A nurse is administering an intravenous (IV) infusion of 2 g cefotaxime dissolved in 100 mL of isotonic glucose solution to a client. The drop factor of the IV tubing is 15 drops/mL.
If the infusion time is 1 hr, what is the gt/min?
400 gt/min
6 gt/min
25 gt/min
9 gt/min
The Correct Answer is C
The gt/min is 25.
This answer is correct because it is based on a simple formula and calculation. The nurse should use the following formula to calculate the gt/min:
gt/min = (Volume in mL x Drop factor in gt/mL) / Time in min
Plugging in the given values, the nurse should get:
gt/min = (100 mL x 15 gt/mL) / 60 min
gt/min = 25
Therefore, the gt/min is 25.

Correct Answer is B
Explanation
This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:
centimeters = inches × 2.54
For example, if a patient's height is 60 inches, then the height in centimeters is:
centimeters = 60 × 2.54
centimeters = 152.4
Therefore, the patient's height is 152.4 centimeters.
Correct Answer is B
Explanation
QD is an abbreviation for "quaque die" which means "every day" in Latin. However, QD is on the official "Do Not Use" list of the Joint Commission because it can be mistaken for QOD, which means "every other day" in Latin¹². This can lead to medication errors and patient harm. Therefore, the Joint Commission recommends writing "daily" instead of QD.
The other options are not on the official "Do Not Use" list of the Joint Commission. OS, PO, and OD are abbreviations for "oculus sinister" (left eye), "per os" (by mouth), and "oculus dexter" (right eye) respectively. They are commonly used in ophthalmology and pharmacy³. However, they should be used with caution and only when appropriate, as they can also be confused with other abbreviations or symbols.
