Updated Critical Care Calculations Exam With Answers

Background of Critical Care Calculations - ANSWER Critical care medications can induce changes in BP and heart rate and require continuous monitoring Accurate calculations of dosages is essential Medications used in critical care can be ordered by dosage (mcg/ min/ kg/h; mcg/ kg/ h) We usually see these types of calculations when you are cardiac floors For these types of questions, it is really important to look at the question to see what it is you need to do EX. IF SOMETHING IS IN MINUTES how do you get to hours? EX. IF SOMETHING IS IN HOURS, how do you get it in minutes? - ANSWER For an example, if it is something per minute, and they are asking for an hour x 60 because there is 60 minutes an hour divide it by 60!
