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 D
Explanation
This answer is correct because it is based on a series of unit conversions and calculations. The nurse should follow these steps to provide safe medication to the child:
1) Convert the child's weight from pounds to kilograms by dividing by 2.2, since there are 2.2 lbs in 1 kg. The child weighs 20 kg.
2) Multiply the prescribed dose per kilogram by the child's weight in kilograms to get the total dose in milligrams. The child needs 40 mg of pyrimethamine.
3) Use the ratio given on the drug label to convert the total dose in milligrams to the volume in milliliters. The nurse can set up a proportion as follows:
1 mg / 5 mL = 40 mg / x mL
Cross-multiplying and solving for x gives:
x = 200 mL
Therefore, the nurse should administer 200 mL of medication to deliver 40 mg of pyrimethamine to the child.
4) Convert the volume in milliliters to the volume in teaspoons by dividing by 5, since there are 5 mL in 1 tsp. The nurse should administer 40 tsp of medication to the child.
5) Convert the volume in teaspoons to the volume in cups by dividing by 48, since there are 48 tsp in 1 cup. The nurse should administer 0.83 cups of medication to the child.
Correct Answer is D
Explanation
To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)
1.5 L = 1500 mL (since 1 L = 1000 mL)
Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.
