The healthcare provider prescribes propofol (Diprivan) at 8 mcg/kg/minute
|! |! |! |! |! |! |! |! |!




for a client during conscious sedation. The drug is dispensed as a econdary
|! |! |! |! |! |! |! |! |! |! |! |! |!




infusion labled, 0.9% normal saline 50 ml with propofol 100 mg/50 ml The
|! |! |! |! |! |! |! |! |! |! |! |! |!




client's weight is 198 pounds. The nurse should program the infusion pump
|! |! |! |! |! |! |! |! |! |! |! |!




to deliver how many ml/hour? (Enter numeric value only. If rounding is
|! |! |! |! |! |! |! |! |! |! |! |!




required, round to the nearest tenth.) - Correct answer ✔21.6
|! |! |! |! |! |! |! |! |!




Rationale:

The client's weight in kg is 90 kg (198 pounds / 2.2 pounds).Next, determine
|! |! |! |! |! |! |! |! |! |! |! |! |! |!




the total mcg in the NS infusion (1 mg : 1000 mcg :: 100 mg : 100,000
|! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |!




mcg)and the IV concentration per ml (100,000 mcg : 50 ml :: X mcg : 1 ml).
|! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |!




100, = 2000 mcg/ml.Then, calculate the prescribed dose
|! |! |! |! |! |! |! |! |! |!




(mcg/kg/min) x 60 min/hour x kilograms divided by concentration |! |! |! |! |! |! |! |! |!




(mcg/ml).8 x 90 x 60 divided by 2000 = 21.6 ml/hour |! |! |! |! |! |! |! |! |! |!




A client weighing 86 kg is receiving dopamine at 8 mcg/kg/minute. The drug
|! |! |! |! |! |! |! |! |! |! |! |! |!




is dispensed as dopamine 800 mg/500 ml. The nurse should program the
|! |! |! |! |! |! |! |! |! |! |! |!




infusion pump to deliver how many ml/hour? (Enter numeric value only. If
|! |! |! |! |! |! |! |! |! |! |! |!




rounding is required, round to the nearest tenth.) - Correct answer ✔25.8
|! |! |! |! |! |! |! |! |! |! |!



|!




Rationale:

, First, change the concentration of dispensed dopamine to mcg/ml. 1 mg :
|! |! |! |! |! |! |! |! |! |! |! |!




1000 mcg :: 800 mg : X mcg = 800,000 mcg/500 ml = 1600 mcg/ ml.Using the
|! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |!




formula, prescribed dose (8 mcg/kg/minute) x 60 minute/hour x weight (86
|! |! |! |! |! |! |! |! |! |! |! |!




kg) divided by the concentration of the available drug (1600 mcg/ml) = 8 x 60
|! |! |! |! |! |! |! |! |! |! |! |! |! |!




x 86 divided by 1600 = 25.8 ml/hour
|! |! |! |! |! |! |! |!




Mineral oil U.S.P 30 ml PO daily for 3 days is prescribed for a client who is
|! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |!




experiencing severe constipation. The dose cup is marked in tablespoons. |! |! |! |! |! |! |! |! |! |!




How many tablespoons should the nurse administer? (Enter numeric value
|! |! |! |! |! |! |! |! |! |!




only.) - Correct answer ✔2 |! |! |! |!




Rationale:

15 ml equals 1 Tablespoon. Use the ratio equation: 15 ml : 1 Tbs :: 30 ml : X
|! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |! |!




:: 1 / X
|! |! |! |! |! |!




15X = 30 |! |!




X = 2 Tablespoons
|! |! |!




Oxytocin (Pitocin) 4 milliunits/minute IV is prescribed for a client with an
|! |! |! |! |! |! |! |! |! |! |! |!




ineffective contraction pattern. To administer the prescribed dosage, the nurse |! |! |! |! |! |! |! |! |!




adds 20 units of oxytocin to Ringer's Lactate 1,000 ml. The infusion pump
|! |! |! |! |! |! |! |! |! |! |! |! |! |!




should be set to deliver how many ml/hour. (Enter numeric value only.) -
|! |! |! |! |! |! |! |! |! |! |! |! |!




Correct answer ✔12 |! |!




Rationale:

4 milliunits/min x 1 unit/1000 milliunits x 1000 ml/20 units x 60 min/hr =
|! |! |! |! |! |! |! |! |! |! |! |! |! |!




240,000/20,000 = 12 ml/hour |! |! |!
