NR 340 Critical Care Practice QuestionsDirections: 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 10 th 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!
