Which abbreviation is on the official "Do Not Use" list of the Joint Commission?

A.

OS

B.

QD

C.

PO

D.

OD

Answer and Explanation

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

To find the volume of fluid that will be left at 10:00 am, you need to calculate the following:

- The time elapsed in minutes from 8:45 am to 10:00 am using the formula: Time elapsed (min) = End time (min) - Start time (min)
- The volume of fluid infused in milliliters (mL) during the time elapsed using the formula: Volume infused (mL) = Flow rate (mL/min) x Time elapsed (min)
- The volume of fluid left in milliliters (mL) at 10:00 am using the formula: Volume left (mL) = Initial volume (mL) - Volume infused (mL)

First, use the formula for time elapsed to find how many minutes have passed from 8:45 am to 10:00 am:

Time elapsed (min) = End time (min) - Start time (min)

Since the end time is 10:00 am and the start time is 8:45 am, plug in these values into the formula:

Time elapsed (min) = 600 min - 525 min

Simplify and solve for the time elapsed:

Time elapsed (min) = 75 min

Next, use the formula for volume infused to find the amount of fluid infused in milliliters during the time elapsed:


Volume infused (mL) = Flow rate (mL/min) x Time elapsed (min)


Since the flow rate is 2 mL/min and the time elapsed is 75 min, plug in these values into the formula:

Volume infused (mL) = 2 mL/min x 75 min

Simplify and solve for the volume infused:

Volume infused (mL) = 150 mL

Then, use the formula for volume left to find the amount of fluid left in milliliters at 10:00 am:

Volume left (mL) = Initial volume (mL) - Volume infused (mL)

Since the initial volume is 1500 mL and the volume infused is 150 mL, plug in these values into the formula:

Volume left (mL) = 1500 mL - 150 mL

Simplify and solve for the volume left:

Volume left (mL) = 1350 mL

Therefore, the volume of fluid that will be left at 10:00 am is **1350 mL**.

Correct Answer is A

Explanation

The IV infusion will be completed at 13:20.

This answer is correct because it is based on a simple division and addition calculation. The nurse can divide the total volume of the infusion by the infusion rate to get the duration of the infusion in hours, as follows:

1000 mL / 250 mL/hr = 4 hr

Therefore, the infusion will take 4 hours to complete. The nurse can add 4 hours to the start time of the infusion to get the end time, as follows:

09:20 + 4:00 = 13:20

Therefore, the IV infusion will be completed at 13:20.
