HESI Dosage Calculation II Practice Tes t 2024 New Latest Version Bes t studying Material with All Questions and Answers Question 1: A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The IV administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.) Show correct answer and explanation Explanation To calculate the gtt/min, use the formula: gtt/min = (volume in mL x drop factor in gtt/mL) / time in min Plug in the given values: gtt/min = (250 mL x 10 gtt/mL) / 120 min Simplify and solve: gtt/min = 2500 gtt / 120 min = 20.83 gtt/min Round to the nearest whole number: gtt/min = 21 The nurse should regulate the infusion at 21 gtt/min Question 2: The healthcare provider prescribes enoxaparin 1 mg/kg subcutaneously every 12 hours for a client who weighs 132 pounds. The medication is available in a 60 mg/0.6 mL prefilled syringe. How many mL should the nurse administer per day? (Enter numerical valu e only.) Show correct answer and explanation Explanation - Convert the client's weight to kilograms: 132 pounds / 2.2 = 60 kg - Calculate the daily dose of enoxaparin: 1 mg/kg x 60 kg x 2 times = 120 mg - Calculate the volume of medication to administer: 120 mg / 60 mg x 0.6 mL = 1.2 mL - The nurse should administer 1.2 mL of enoxaparin per day. Question 3: The healthcare provider prescribes amoxicillin 500 mg every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hour. The available suspension is labeled, Amoxicillin Suspension 250 mg/5 mL. Based on this child wei ght, how many mL should the nurse administer ? (Enter numerical value only. (If rounding is required, round to the whole number.) Show correct answer and explanation Explanation - To calculate the dose in mL, use the formula: Dose (mL) = Dose (mg) / Concentration (mg/mL) - The child's weight in kg is .2 = 40 kg - The maximum safe dose for the child is 50 x 40 = 2000 mg per day - The prescribed dose for the child is 500 x 3 = 1500 mg per day, which is below the maximum safe dose - The dose in mL for each administration is 500 / () = 10 mL - The nurse should administer 10 mL of amoxicillin suspension every 8 hours Question 4: Filgrastim 5 mcg/kg/day subcutaneous is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled 300 mcg/mL. How many mL should the nurse administer daily to this child? (Enter the numerical value only. If rounding required, round to the nearest tenth.) Show correct answer and explanation Explanation - Convert pounds to kilograms: .2 = 40 kg - Calculate the daily dose in mcg: 5 x 40 = 200 mcg - Calculate the volume in mL: = 0.67 mL - Answer: 0.7 mL Question 5: The healthcare provider prescribes liraglutide 1.2 mg subcutaneously daily for a client with type 2 diabetes mellitus. The liraglutide Pen contains 18 mg of liraglutide and will deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. When teaching the client about th e use of the liraglutide Pen, how many doses should the nurse tell the client is available in each Pen? (Enter the numerical value only.) Show correct answer and explanation Explanation - The liraglutide Pen contains 18 mg of liraglutide. - The Pen can deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. - The healthcare provider prescribed 1.2 mg daily for the client. - To calculate the number of doses in each Pen, divide 18 mg by 1.2 mg. - The answer is 15 doses per Pen. Question 6: A client receives a prescription for amoxicillin 2 g/clavulanate 125 mg by mouth every 12 hours for 10 days. The medication is available in 1000 mg/62.5 mg extended -release tablets. How many tablets should the nurse administer? (Enter numerical value only .) Show correct answer and explanation Explanation - To calculate the number of tablets, divide the prescribed dose by the available dose. - Prescribed dose: 2 g amoxicillin + 125 mg clavulanate - Available dose: 1000 mg amoxicillin + 62.5 mg clavulanate - Number of tablets = (2 g / 1000 mg) + (125 mg / 62.5 mg) - Number of tablets = 2 + 2 - Number of tablets = 4 - The nurse should administe r 4 tablets every 12 hours for 10 days. Question 7: The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D5 0.5% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume control administration set with a microdrip chamber to the bag of solution. How many mic rodrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.) Show correct answer and explanation Explanation - Calculate the hourly volume in mL: 45 mL/hour - Convert the hourly volume to minute volume: 45 mL/hour ÷ 60 minutes/hour = 0.75 mL/minute - Multiply the minute volume by the drop factor: 0.75 mL/minute x 60 microdrops/mL = 45 microdrops/minute - The nurse should regulate the infusion at 45 microdrops/minute Question 8: The healthcare provider prescribes heparin 1,400 units/hour intravenously (IV). The IV bag contains heparin 20,000 units in 250 mL dextrose 5% in water. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
