Which abbreviation is on the official "Do Not Use" list of the Joint Commission?
OS
QD
PO
OD
The Correct Answer is B
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.

Correct Answer is A
Explanation
To find the milligrams per minute, you need to calculate the following:
- The volume of Lopressor in milliliters
- The infusion rate in milliliters per minute using the formula: Infusion rate (mL/min) = Total volume (mL) / Time (min)
- The dose of Lopressor in milligrams per minute using the formula: Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)
First, divide the dose of Lopressor by the concentration to get the volume in milliliters:
5 mg / 1 mg/mL = 5 mL
Next, use the formula for infusion rate to find how many milliliters per minute the IV pump should deliver:
Infusion rate (mL/min) = Total volume (mL) / Time (min)
Since the total volume is 5 mL and the time is 2 minutes, plug in these values into the formula:
Infusion rate (mL/min) = 5 mL / 2 min
Simplify and solve for the infusion rate:
Infusion rate (mL/min) = 2.5 mL/min
Then, use the formula for dose to find how many milligrams per minute the patient should receive:
Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)
Since the infusion rate is 2.5 mL/min and the concentration is 1 mg/mL, plug in these values into the formula:
Dose (mg/min) = 2.5 mL/min x 1 mg/mL
Simplify and solve for the dose:
Dose (mg/min) = 2.5 mg/min
Therefore, the patient should receive **2.5 mg/min** of Lopressor.
