30.A patient has orders to receive 3,000 mL of IV fluid at a rate of 150 mL/h. If the infusion starts at 08:00, when would it be finished? A)20:00B)23:00C)01:00D)04:00Ans:D
Feedback:Amount of fluid to infuse = 3,000 mL; rate of infusion = 150 mL. 3,000 ÷ 150 mL = 20 hours to infuse. There are 24 hours in a day 20 hours = 4 hours. The infusion will complete in 4 hours before 08:00 (08:00 04:00 = 04:00 hour) so the infusion completes at 04:00. 31.The nurse recognizes that what system is being used when seeing a medication ordered in minims?
32.The nurse is calculating the patient’s intake and output record and converts ounces to milliliters. What systems is this nurse converting from and to? 33.What is the most accurate method for the nurse to use when determining a pediatric dosage?
34.The nurse determines a child’s body surface area is 0.4 m2 and the average adult dosage of the medication is 500 mg. The medication is supplied in liquid form with 500mg/5 mL.How many milliliter will the nurse administer? A)3.46 mLB)1.73 mLC)0.5 mLD)12 mL
Ans:AFeedback:The formula for calculating the child’s dose using body surface area is surface area in m2 divided by 1.73 and then multiplied by adult dosage. Using the information supplied in this problem (0.4 ÷ 1.73) × 500 mg = 346 mg. Using the ratio and proportion method, 500 mg/5 mL = 346 mg/X mL; cross-multiplying yields 3.46 mL for the nurse to administer. 35.The physician orders acetaminophen (Tylenol) 15 mg/kg q4 hours PRN (as needed) for pain. The drug is supplied with 160 mg/5 mL. The infant weighs 12 pounds. How many milliliter of medication will the nurse administer? Feedback:
