A patient receives an intravenous (IV) solution that flows at the rate of 150 mL per hour. How much fluid does the patient receive in 20. min? (Answer = 50 mL) How long does it take for the patient to receive 90. mL of fluid? (Ans. = 0.6 hr or 36 min.) If the IV bag holds 600. mL of fluid, how many minutes does it take to empty the bag? (t = 4 hrs) If the solution contains 90. mg of glucose per mL, how long will it take to give the patient 2.0 g of glucose? (t = 0.15 hr or 9 min)
Order: Start Pitocin at 1.5 milliunits/min, titrate up to 20 milliunits/min, Increase the rate of infusion by 2 milliunits/min q 15minutes. Available: Normal Saline with 10 units Pitocin per liter.

A 72-year-old adult patient who weighs 78 kg is prescribed by the doctor “Potassium Chloride 40meq in 1L to run for 8 hours” via the peripheral line for a potassium level of 3.3 mEq/L that was drawn this morning. Note: 10 mEq of potassium chloride increases serum potassium levels by approximately 0.1 mEq/.L The concentration of potassium for intravenous administration via a peripheral line should not exceed 40mmol / 500 mL 10 mEq/hr maximum infusion rate; not to exceed 200 mEq dose/24hr Administration rates above 20mmol/hour require cardiac monitoring. How much will the order medication “Potassium Chloride 40meq in 1L to run for 8 hours” raise the patient's potassium level in a day? Is it still within the normal potassium serum levels, which is 3.5–5.0 mEq/L? Does the order comply with the maximum concentration of potassium to be administered peripherally? Does the order’s infusion rate do not exceed the standard maximum infusion rate? Does the order require cardiac monitoring?

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.
