ISMP List of Error-Prone Abbreviations, Symbols, and Dose Designations

Question 1

Question: Why should you avoid using “U” for “unit”?

Answer 1

Answer: “U” can be mistaken for “0,” “4,” or “cc,” leading to serious dosage errors. For example, “10U” might be misread as “100” or “40.” Instead, always write “unit.”
Visual Example:
An image showing:

Incorrect: “10U” (interpreted as “100” or “40”).
Correct: “10 units” (clear and unambiguous).

Question 2

Question: Why should “IU” not be used?

Answer 2

Answer: “IU” can be confused with “IV” (intravenous) or the number “10.” This may result in administering the wrong type or amount of medication. Always write “international unit” instead.
Visual Example:
A comparison:

Incorrect: “IU” misread as “IV” or “10.”
Correct: “International unit” clearly written out.

Question 3

Question: Why should “QD” (daily) and “QOD” (every other day) not be used?

Answer 3

Answer: These abbreviations are often mistaken for each other. For example, the “Q” in “QD” can look like an “I,” and “QOD” might be misread as “QID” (four times a day). Instead, write “daily” or “every other day.”
Visual Example:
An image showing:

Incorrect: “QOD” being read as “QID.”
Correct: “Every other day” or “daily.”

Question 4

Question: Why are trailing and leading zeros problematic?

Answer 4

Answer: A trailing zero (e.g., “1.0 mg”) might be read as “10 mg” if the decimal is missed. Similarly, a lack of a leading zero (e.g., “.5 mg”) might be read as “5 mg.” To avoid errors, write “1 mg” and “0.5 mg.”

Visual Example:
A side-by-side comparison:

Incorrect: “1.0 mg” (misread as “10 mg”), “.5 mg” (misread as “5 mg”).
Correct: “1 mg,” “0.5 mg.”

Question 5

Question: Why shouldn’t you use “MS,” “MSO₄,” or “MgSO₄”?

Answer 5

Answer: These abbreviations can mean either morphine sulfate or magnesium sulfate, leading to confusion and potentially dangerous errors. Always write the full name, like “morphine sulfate” or “magnesium sulfate.”

Visual Example:
A table:

Incorrect: “MS,” “MSO₄,” “MgSO₄” (ambiguous).
Correct: “Morphine sulfate,” “Magnesium sulfate.”

Question 6

Question: Why shouldn’t we write “U” for “unit”?

Answer 6

Answer: Imagine someone thinking the “U” is a “0” or a “4.” That could turn “10U” into “100” or “40,” which would be a big mistake! Writing “unit” instead keeps things safe and easy to understand.

Visual Example:
Think of it like saying, “Bring me 10 apples,” instead of writing “10A.” If “A” looks like “40,” someone might bring too many apples!

Question 7

Question: Why is “IU” confusing?

Answer 7

Answer: It might look like “IV” (medicine given through a vein) or the number “10.” That’s a big difference, right? So, it’s better to write “international unit” to make it clear.

Visual Example:
It’s like saying, “Please bring ice cream!” instead of writing “IC.” What if someone reads it as “IV” and brings an ivy plant instead of a treat?

Question 8

Question: Why are “QD” and “QOD” tricky?

Answer 8

Answer: These abbreviations can look like other ones. “QD” (daily) might look like “QID” (four times a day), and “QOD” (every other day) could be misunderstood, too. Writing “daily” or “every other day” makes everything simple.

Visual Example:
Imagine writing, “Go to bed at QD,” and someone thinks you mean “four naps a day!” Instead, say, “Go to bed daily,” and there’s no confusion.

Question 9

Question: Why are decimals like little troublemakers?

Answer 9

Answer: If you write “1.0 mg,” someone might miss the dot and think it’s “10 mg.” Or, if you write “.5 mg” without a zero, it might look like “5 mg.” Writing “1 mg” or “0.5 mg” makes sure no one gets confused.

Visual Example:
It’s like drawing tiny polka dots on a shirt—if they’re too small, someone might think the shirt is plain. Add a zero (like adding a frame), and it’s clear to everyone!

Question 10

Question: Why shouldn’t we write “MS” for medicine names?

Answer 10

Answer: “MS” could mean two completely different medicines—morphine sulfate or magnesium sulfate. Writing the full name tells everyone exactly what you mean, no guessing.

Visual Example:
It’s like calling two of your friends “Sam.” When you shout “Sam!” at the park, both of them show up. But if you say, “Sam the tall one” or “Sam with glasses,” everyone knows who you mean.

Question 11

Question: Why do we need to be so careful about these rules?

Answer 11

Answer: Because every little word and number can protect someone’s health! When we write clearly, no one has to guess, and patients get the right care. Isn’t it amazing how something so simple can make such a big difference?

Visual Example:
It’s like leaving a trail of bright breadcrumbs in the woods. If the path is clear, everyone can follow it safely without getting lost.

Question 12

Visual Example:
It’s like asking for 1 grain of sand but someone gives you 1 whole bucket because they couldn’t tell what you meant. Writing “mcg” is like pointing to the exact grain you need.

Question 20

Question: Why shouldn’t we write “AD,” “AS,” or “AU” for ear instructions?

Answer 20

Answer: These short forms mean “right ear,” “left ear,” and “each ear,” but they can look like “OD,” “OS,” or “OU,” which are for eyes. Imagine putting ear drops in your eye—ouch! Writing “right ear” or “left ear” makes everything clear.
Visual Example:
It’s like labeling two bottles “R” and “L” but forgetting to say if it’s for your hands or feet. Better to just write “right ear” or “left ear.”

Question 21

Question: What’s tricky about using “OD,” “OS,” or “OU” for eyes?

Answer 21

Answer: These mean “right eye,” “left eye,” and “each eye,” but someone might think they’re for ears instead. Writing “right eye” or “left eye” means no one gets mixed up.
Visual Example:
It’s like saying, “Use this for OD” but someone thinks you mean a different part of your body. Writing “right eye” is like putting a big, clear label on it.

Question 22

Question: Why shouldn’t we write “BT” for bedtime?

Visual Example:
Imagine writing “Give 5 Cc,” and someone thinks it’s “5 units” of something else. Writing “5 mL” is like pointing to the exact cup size you need.

Question 24

Question: Why is “D/C” confusing?

Answer 24

Answer: “D/C” could mean “discharge” (sending someone home) or “discontinue” (stopping medicine). If someone guesses wrong, they might stop the medicine too early. Writing “discharge” or “discontinue” makes sure no one has to guess.
Visual Example:
It’s like writing “D/C your chores,” and someone thinks it means “stop doing chores forever” instead of “take a break after finishing.” Writing it clearly avoids all the confusion.

Question 25

Question: Why isn’t “IJ” good for injection?
