For example, a problem that gives an answer of 100 mg maybe expressed as 0.1 gram . Similarly, 0.5 mg could be expressed as 500 mcg or 0.0005 grams.  \nUse the information provided for questions 1 through 3. You receive an order for 500 mg of aminophylline in normal saline in a total volume of 250 ml. The patient weighs 132 pounds. The aminophylline is to be administered at a dose of 0.3 mg per kg per hour. Aminophylline Injection is supplied in vials with 25 mg per ml. The IV set you will use delivers 60 drops per ml.  \n1. How many milligrams of theophylline will the patient receive each hour?  \n2. How many hours will the 250 ml last if administered at the correct dose?  \n3. What will be the flow rate, in drops per minute , to administer the dose ordered?  \n4. A dose of 120 mg of gentamicin is administered IV . After 10 minutes, a blood sample is assayed forgentamicin content. The result is 8 mcg per ml. What is the volume of distribution for gentamicin?  \nUse the prescription shown for questions 5 through 8.  \nYou have tablets that contain 0.25 mg of reserpine per tablet. You can mix ground up reserpine tablets in cherry syrup to make a liquid that will be stable for at least 3 months. The patient is a child that weighs 22 pounds.  \nReserpine Liquid 0.1 mg per ml Disp: 60 ml  \nSig: 0.01 mg per kg per dose one dose twice a day  \n5. How many reserpine tablets will be needed to compound the prescription?  \n6. What volume (ml) will be in each dose?  \n7. How long will this prescription last at the dose ordered?  \n8. If reserpine tablets cost $20.00 per 100 tablets, what will be the cost of the tablets used?  \nQuestions 9 and 10. You need to prepare 30 grams of 0.25% triamcinolone in Cold Cream. Triamcinolone is available in a suspension of 40 mg per ml that has a specific gravity of 1.0.  \n9. How many ml of the triamcinolone solution will be needed?  \n10. How many grams of the Cold Cream will be needed?  \nQuestion 11 thru 13. You are to mix this IV using the materials shown. You must ADD the volumes of the dextrose and NaCl to the 1000 ml of Sterile Water.  \n11. How many ml of the Sodium Chloride Injection, 23.4%, will you add to the sterile water?  \n12. How many ml of the Dextrose 70% in Water Injection will you add to the sterile water?  \n13. After all of the ingredients are mixed, what will be the flow rate in milliliters per hour?  \n\n| Sterile Water for Injection Dextrose\u003Cbr>Sodium chloride Administer over 24 hours | 1000 ml 10 %\u003Cbr>60 mEq |\n| --- | --- |\n| Sterile Water for Injection , 1000 ml Sod Chloride Inj, 23.4%(MW = 58.5) Dextrose 70% in Water Injection |  |\n\nWhen doing flow rates you wind up expressing your answer in ml per hour, ml per minute, or drops per minute. The most common flow rates for large volume IV fluids range from 75 to 125 ml per hour but smaller and larger rates are possible to correct volume deficits (rarely greater than 250 ml per hour) or to simply keep an IV line open and flowing (KVO, or keep vein open rate) at 42 ml per hour.  \nIV sets generally deliver 10 , 12 , 15 or 20 drops per ml (for adult IV sets) and 60 drops per ml (for pediatric IV sets) . Since a drop rate implies that the nurse is going to actually count the drops falling in the drop chamber, ask this simple question – how high can you count in one minute? Few people would say they could count to 100 in one minute, Therefore, your drops per minute rate must by less than 100 to be realistic and 60 is a more likely number. NOTE: With a pediatric IV set (60 drops per ml) flow rate in ml per hour = drops per minute.  \nIf one liter (1000 ml) of fluid is to be administered, then 125 ml/hr = 8 hr; 100 ml/hr = 10 hr; 84 ml/hr = 12 hr; 75 ml/hr = 14 hr; and 42 ml/hr = 24 hr.  \n4. Vd =  Dose  8 mcg/ml = 8 mg/liter Vd =  120 mg  = 15 liters Co 8 mg/L  \n5. 60 ml (x) 0.1 mg/ml = 6 mg reserpine needed  6 mg  = 24 tabs nee","cbCaiqityMwfp4qD","https://ap.wps.com/l/cbCaiqityMwfp4qD","pdf",96403,"English","# IV infusion and dosing calculations\n## Aminophylline/theophylline dosing and infusion rate\n## Gentamicin volume of distribution\n## Reserpine compounding and prescription duration\n## Triamcinolone preparation from suspension and specific gravity\n## Mixing IV components and final flow rate\n# Flow rate and unit conversion principles\n## Drops per minute and IV set drop factors\n## Example infusion duration for common flow rates\n# Buffer and concentration/stoichiometry computations\n## pH/pKa and acetate-acetic acid equivalence\n## Molecular weight and moles for acetate buffer\n## Salt hydration, mEq conversions, and practical dosing examples","[{\"question\":\"How do you determine the patient’s theophylline dose per hour from an aminophylline order?\",\"answer\":\"Convert the ordered aminophylline dose into theophylline equivalents using the stated relationship in the problem, then compute the hourly amount based on the prescribed mg/kg/hour regimen.\"},{\"question\":\"How is the infusion flow rate calculated in drops per minute for the ordered dose?\",\"answer\":\"First determine the required ml per hour from the dose and solution concentration, then convert to drops per minute using the IV set’s drops per ml (e.g., 60 drops/ml for pediatric sets).\"},{\"question\":\"How do you compute reserpine tablets needed and the dose volume per administration?\",\"answer\":\"Use the prescribed mg per kg per dose to calculate total mg per dose, then convert mg to tablets using the tablet strength (0.25 mg/tablet).
