A patient with esophageal varices received octreotide (Sandostatin) 100 microgram intravenous bolus and the nurse is preparing to start a continuous infusion of the medication. The drug is diluted 500 micrograms in 250 mL of 0
9% normal saline to be administered at 50 mcg/hour. How many milliliters per hour should the intravenous infusion pump be set to deliver the correct dose? 1. 100 mL
2. 50 mL
3. 12.5 mL
4. 25 mL

Rationale 1: The rate of 25 L/hr may be correctly calculated by using the formula: Dose divided by concentration equals rate. The dose is 50 mcg/hour divided by the concentration (500 mcg/ 250 mL). This is 50 divided by 2 = 25 mL/hour.
Rationale 2: The rate of 25 L/hr may be correctly calculated by using the formula: Dose divided by concentration equals rate. The dose is 50 mcg/hour divided by the concentration (500 mcg/ 250 mL). This is 50 divided by 2 = 25 mL/hour.
Rationale 3: The rate of 25 L/hr may be correctly calculated by using the formula: Dose divided by concentration equals rate. The dose is 50 mcg/hour divided by the concentration (500 mcg/ 250 mL). This is 50 divided by 2 = 25 mL/hour.
Rationale 4: The rate of 25 L/hr may be correctly calculated by using the formula: Dose divided by concentration equals rate. The dose is 50 mcg/hour divided by the concentration (500 mcg/ 250 mL). This is 50 divided by 2 = 25 mL/hour.
