NR 340 Critical Care Practice Questions 2020 with all the correct answers

Directions: The purpose of this packet is to prepare you for the medication calculation exam that is taken on the first day of class. Complete the medication calculation practice exam prior to the first day of class if needed. In critical care, amounts are specific. If the calculation is not a whole number, then answers are rounded off to the nearest 10th decimal place. Pumps can be programmed to allow for a 10th decimal place. If the calculation is for drops per minute then it is rounded off to the nearest whole number because drops cannot be divided. Good Luck!
