Question

 QUESTION 8

 A nurse is preparing to administer hydrocortisone sodium succinate 250 mg via IV bolus every 6 hours. Available is hydrocortisone sodium succinate 1000 mg/8 mL How many mL. should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

 

 QUESTION 9

 A nurse is preparing to administer lidocaine 50 mg IV bolus. Available is lidocaine 200 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

 QUESTION 10

 A nurse is preparing to administer heparin 2,000 units by IV bolus. Available is heparin injection 5,000 units/mL. How many ml, should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

8. Nurse administer the dose of 250 mg every 6 hours.

Available is hydrocortisone sodium succinate 1000 mg/8 mL.

It means, 8 mL contains 1000 mg.

So for 250 mL, the volume taken can be calculated as

1000/8 = 250/X

X = 250/125

X = 2 mL

So, 2 mL should be administer to deliver the required dose.

9. Nurse is preparing to administer lidocaine 50 mg IV bolus.

Available is lidocaine 200 mg/mL.

It means the available formulation contains 200 mg in 1 mL

So for 50 mg administration, the volume is to be taken can be calculated as:

200/1 = 50/X

X = 50/200

X = 0.25 mL

So, 0.25 mL of the available lidocaine should be administer to deliver the required dose

10. Nurse is preparing to administer heparin 2000 units by IV bolus.

Available is heparin 5000 units/mL

It means the available formulation contains 5000 units of heparin in 1 mL.

So for 2000 units of heparin administration, the volume is to be taken can be calculated as:

5000/1 = 2000/X

X = 2000/5000

X = 0.4 mL

So, 0.4 mL of the available heparin should be administer to deliver the required Units of heparin.
