Question

The healthcare provider prescribes amiodarone 0.5 mg/min intravenously (IV) for a client with a ventricular dysrhythmia. The IV bag contains amiodarone 360 mg in dextrose 5% in water (D5W) 200 mL. How many mL/hour should the nurse program the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer 1

Correct Answers:

17

Rationale :

🎯 Step 1: Convert prescribed rate from mg/min to mg/hr

0.5 mg/min×60

30 mg/hr

🎯 Step 2: Identify the concentration from the IV bag

360 mg in 200 mL

Concentration=360/200

1.8 mg/mL

🎯 Step 3: Use the volume–dose formula

mL/hr=30 mg/hr/1.8 mg/mL

16.67

🎯 Step 4: Round to the nearest whole number

17 mL/hr

Answer 2

Correct Answers:

3000

Rationale :

✍️ Step 1: Convert the prescribed rate from mg/min to mg/hr

10 mg/min×60

600 mg/hr

✍️ Step 2: Determine the concentration of the IV solution

50 mg/250 mL

0.2 mg/mL

✍️ Step 3: Use the volume–dose formula

mL/hr=600 mg/hr/0.2 mg/mL

Answer 3

Correct Answers:

75

Rationale :

📌 Step 1: Identify the prescribed dose

15 mg/hour

📌 Step 2: Determine the concentration from the IV bag

50 mg in 250 mL

Concentration=50/250

0.2 mg/mL

📌 Step 3: Use the volume–dose formula

mL/hr=15 mg/hr/0.2 mg/mL

75 mL/hr

Answer 4

Correct Answers:

83

Rationale :

💎Step 1: Identify total volume and time

Volume = 500 mL

Time = 2 hours × 60 = 120 minutes

💎 Step 2: Drop factor

20 gtt/mL

💎 Step 3: Use the drip rate formula

gtt/min=Volume (mL)×Drop factor (gtt/mL)/Time (min)

500×20/120

💎 Step 4: Calculate and round

10,000/120

83.33

83 gtt/min

Answer 5

Correct Answers:

3.8

Rationale :

🎯 Step 1: Determine weight-based dose

Client weight = 35 pounds

Falls in 34 to 50.6 lb range

Prescribed dose = 45 mg per dose

🎯 Step 2: Use the volume–dose formula

Labeled concentration = 12 mg/mL

Volume (mL)=45/12

3.75 mL

🎯 Step 3: Round to the nearest tenth

3.8 mL

Answer 6

Correct Answers:

10

Rationale :

✍️ Step 1: Identify total volume and time

Volume = 250 mL

Time = 24 hours

✍️ Step 2: Use the infusion rate formula

mL/hr=250/24

10.42

✍️ Step 3: Round to the nearest whole number

10 mL/hr

Answer 7

Correct Answers:

0.75

Rationale :

💎 Step 1: Identify the concentration after reconstitution

0.3 mg in 1.2 mL

Concentration=0.3/1.2

0.25 mg/mL

💎 Step 2: Use the volume–dose formula

Volume (mL)=0.1875 mg/0.25 mg/mL

0.75 mL

Answer 8

Correct Answers:

80

Rationale :

🎯 Step 1: Convert weight from pounds to kilograms

132÷2.2

60 kg

🎯 Step 2: Calculate prescribed dose in mcg/min

2 mcg/kg/min×60 kg

120 mcg/min

🎯 Step 3: Convert mcg/min to mg/hr

120×60

7200 mcg/hr

7.2 mg/hr

🎯 Step 4: Determine dopamine concentration

45 mg in 500 mL

45/500

0.09 mg/mL

🎯 Step 5: Use the volume–dose formula

mL/hr=7.2 mg/hr/0.09 mg/mL

80 mL/hr

Answer 10

Correct Answers:

80

Rationale :

✍️ Step 1: Convert weight from pounds to kilograms

132÷2.2

60 kg

✍️ Step 2: Calculate prescribed dose in mcg/min

2 mcg/kg/min×60

120 mcg/min

✍️ Step 3: Convert mcg/min to mcg/hour

120×60=7200 mcg/hr

✍️ Step 4: Convert mcg/hr to mg/hr

7200÷1000

7.2 mg/hr

✍️ Step 5: Calculate dopamine concentration in IV solution

45 mg/500 mL

0.09 mg/mL

✍️ Step 6: Use the volume–dose formula

mL/hr=7.2/0.09
