Exam (elaborations) Critical Care Calculations

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! A solution of Labetalol 100 mg in 100 mL of D5W is to infuse at a rate of 25 mg/ h. Calculate the IV flow rate - ANSWER 25 mL/hour A solution of lidocaine 125 mg in 100 mL is to infuse at a rate of 20 mg/h. Calculate the flow rate in mL/h. Use either method. - ANSWER 16 mL/hour A solution of lidocaine 50 mg in 200 mL is to infuse at 6mg/h. Calculate the flow rate in mL/h. Use either method - ANSWER 24 mL/hour Isoproterenol 5 mcg/min has been ordered. The solution strength is 2 mg of isoproterenol in 250 mL solution of D5W. Calculate the flow rate (mL/h). - ANSWER 38 mL/hour Dopamine 2 mcg/min has been ordered. The solution strength is dopamine 1 mg of dopamine in 250 mL of D5W. Calculate the flow rate (mL/h). - ANSWER 30 mL/hour Nitroprusside has been ordered at the rate of 3 mcg/min. The solution strength is 8 mg of nitroprusside in 250 mL of 0.9% sodium chloride. Calculate the flow rate (mL/h). - ANSWER 6 mL/hour
