An 84 year old male patient has been given a loading dose of digoxin of 298 micrograms in divided doses by intravenous infusion. He has a creatinine clearance (Ccr) of 34 ml / min. What is the maintenance dose (in micrograms) that this patient should receive? Round your answer to the nearest whole number. Use the formula provided to calculate the maintenance dose. Maintenance Dose = Peak body stores x % daily loss 100 Where: Peak Body Stores = Loading Dose % Daily Loss = 14 + Creatinine clearance (Ccr) 5

Erthy is given an intravenous antibiotic (gentamicin) at a dose of 7 mg/kg per day for a period of 7 days. This dose will be assessed after a week and adjusted accordingly. The gentamicin will be administered in 87 mL of Normal Saline (NS) over a time period of 20 minutes. Please answer the following questions: a. How much will Erthy be getting per day in mg based on this order?b. How much volume of the gentamicin (in mL) should be added to the IV bag; the concentration of gentamicin is 10 mg per mL.
Erthy is given an intravenous antibiotic (gentamicin) at a dose of 7 mg/kg per day for a period of 7 days. This dose will be assessed after a week and adjusted accordingly. The gentamicin will be administered in 87 mL of Normal Saline (NS) over a time period of 20 minutes. Please answer the following questions: How much will Erthy be getting per day in mg based on this order? How much volume of the gentamicin (in mL) should be added to the IV bag; the concentration of gentamicin is 10 mg per mL. By including the volume of the gentamicin solution added to the IV bag (i.e. the volume of the bag will be 87 mL plus the volume of the gentamicin solution), calculate the IV flow rate for this infusion in both mL/min and mL/hr.
