Guidelines for Rounding Critical Care Meds
| Critical care medications are usually administered via pump or controller | If pump can be set to administer meds to the hundredths' place, carry the problem to the thousandths and round to the hundredths |
| The smaller the number the more important it becomes to not round too soon | This is especially true for pediatric patients |
