Hello all, i am currently brushing up on more dosage calculations and i need help on the following problems: 1. Order is to give amoxicillin 125mg suspension p.o. Every 6 hours. You have available 250mg/5ml of amoxicillin. How many ___ml will you give each dose? How many ___mg/24 hours will this patient receive? I only need the second part. 2. The physician orders 500ml of 5%dw to run 150ml per hours. How many drops per minute should the iv drip (15 gtt/ml set)? 3. Order 500ml 20% dw iv are to be infused in 4 hours. The drop factor is 15 gtt = 1ml. How many milliliters per hour will the patient receive? This is how i solved the problem. 500ml divide by 4 hrs = 125ml/hr (is this right?) 4. The physician orders 1000 ml of lr to run over a 24 hour period. How many microdrops per minute should the iv drip (60 gtt/ml set) this is how i solved the problem. 1000ml divide by 24 hrs = 42 gtt/per (is this right?) 5. Order: 500 ml 5% d/w, with 4 g of mgs04 20% solution. Patient to receive 1 g per hour. Calculate the infusion rate if the drop factor is 15 gtt = 1 ml. How many ml/hr? 6. Order: 50 cc 5% d/w with 1 g ampicillin (omnipen) iv in 20 minutes. Calculate the rate of flow in ml/per hour and gtts/ml using 15 gtt/ml? This is how i solved the problem. 60 min divide by 20 min = 3 min 50ml x 3 min = 150 ml/hr 50ml x 15 gtt/ml divide 20 min = 38 gtt/ min (is this right?) 7. The patient must receive 500 u of heparin iv every hour. If the order is "add 10,000 u of heparin to 1000 ml of 5% d/w." how many drop per minute will the patient receive? Drop factor 15 gtt = 1 ml. Hint: the patient would be on an iv pump so you would basically sovle for the ml/hr. 8. The iv in progress is 1000 ml of normal saline with 10 meq of kci, and 800 ml remain to be infused. The order is to increase the kci to 40 meq per liter. How many meq of kci will you add to the 800 ml remaining? This might occur in a critical care unit, but unlikely out on a med-surg floor. 9. Doctor has ordered heparin infusion of 25,000 units in 500 ml of 5% dw to run at 75 u/min. How many ____units will you be administering per hour? How many ___ ml will you be infusing per hour? 10. Physician's order: 500cc 5% d/w with 2 gm of lidocaine iv. How many drops per minute would you administer if the patient must receive 2mg/min? The drop factor is 15 gtt = 1 ml. 11. Order 1000cc 5% d/w are to be infused with 10,000 u hepain iv. If the rate of flow 30 gtt/min and the drop factor is 10 gtt = 1 ml, how many milliliters per hour will the patient receive? 12. Order 500 ml 5%d/w with 4 g of mgso4 20% solution. Patient to receive 1 g per hour. Calculate the infusion rate if the drop factor is 15 gtt = 1 ml/hr? 13. The patient must receive 500 u of heparin iv every hour. If the order is "add 10,000 u of heparin to 1000 ml of 5% d/w, how many drops per minute will the patient receive? Drop factor 15 gtt = 1 ml. Thanks in advance!!!
