What is the most common adverse side effect of IV push valium?
Correct Answer
D. Respiratory depression
Explanation
The most common adverse side effect of IV push valium is respiratory depression. Valium is a benzodiazepine medication that acts as a central nervous system depressant. It can cause a decrease in respiratory rate and depth, leading to respiratory depression.
