The “u” should never be used in a medication order; rather, for safety, the word
j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$
“units” should be spelled out. The other answer options contain the required

Tall man lettering highlights a portion of the drug name to help distinguish from
j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$ j$
similar drug names. It is not used to identify high alert drugs, highlight a boxed
