[Verified Answer]: Part I. Determine the medication amount and me

Part I. Determine the medication amount and method of delivery for each of the following scenarios. Please show your work, including your set-up using standard dimensional analysis. Neatness counts! 1. A physician orders 1000 mg of Amikin IM for a patient with a post-op infection. The label for the medication indicates 200 mg / 2 ml. 2. A physician orders 15 mg of Membutal elixir to treat a patient with insomnia. It is available as 25 mg in 5 ml. 3. A physician orders 2.4 million IU of penicillin G benzathine (Bicillin). The medication comes in premixed syringes, and your clinic stocks two syringe types one at 0.6 million IU/syringe, and the other at 1.2 million IU/syringe. 4. A physician orders 120 mg of a drug which is available in tablet form. The label reads 1 gr/tab. (Use the conversion equivalent of 1 gr (grain) = 60 mg) 5. A physician orders 60 mEq of potassium gluconate elixir for a patient with hypokalemia (low levels of potassium in the blood) caused by diabetic acidosis. The medication label reads 20 mEq/15 cc. How many teaspoons should be given? (1 tsp = 5ml) 6. You need to administer 0.25 mg of Lanoxin. The label reads .125 mg/tab. How many tablets should you give? 7. A patient is prescribed 15 mEq of KCl IV, and the label reads 5 mEq /5mL. How many milliliters should the patient receive? 8. The phenobarbital elixir label states 15 mg/5ml. The patient is prescribed 45 mg of the drug. How many mL should be administered? 9. The physician orders 25 mg of Compazine IM. The label reads 10 mg/mL. How much medicine should be injected? 10. A doctor orders 70mg stat of Acetaminophen Elixir to a 6-year old patient with a fever of 102.6 F. The bottle contains 120mg per 5mL in a 100mL bottle. How many mL should the child receive? (more) Calculating Pediatric Doses The 4 Step Method: Step 1 Convert pounds to kg (1kg = 2.2 lbs) You may have to convert pounds and ounces to decimal pounds (1lb = 16 oz) Step 2 Calculate the dose in mg Step 3 Divide the overall (daily) dose by the frequency (BID, TID, etc.) Step 4 Calculate the dose in mL or tablets Example A 1.5-year-old child is prescribed an amoxicillin suspension. The dose prescribed is 40 mg/kg/day divided into equal BID doses. The suspension is available in a 400mg/5mL suspension. What is the dose in mL? The child weighs 22 pounds. Calculate the following pediatric medication doses using the 4 Step body weight method. This method is also described in Kinns p. 569. 1. A child with a diagnosis of otitis media is prescribed Zithromax suspension 10 mg/kg/day BID 5 days. The patient weighs 33 lbs. The suspension is labeled 150 mg / 5ml. How much medication should the child be given per dose? (1kg=2.2lbs) (more) 2. An infant who weighs 14 lb 12 oz is prescribed erythromycin q6h. The label states that there is 250 mg of the drug in 5 cc of suspension. The recommended dose of the medication for infants is 30 mg/kg/day. How much should the child receive per dose? 3. A pediatrician prescribes 30 mg/kg q8h aztreonam IM, for a child with a urinary tract infection. The child weighs 44 lbs. The manufacturer recommends the medication be administered IM TID (3 times a day), not to exceed 120 mg/kg/day. According to the doctors order, how many milligrams should the child receive per dose? Is this within the manufacturers recommended dosage?
