Question

The healthcare provider prescribes epoetin alfa 8,200 units SUBQ for a client with chronic kidney disease (CKD). The 2 mL multidose vial is labeled, "Each 1 mL of solution contains 10,000 Units of epoetin alfa." How many mL should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth)

Answer 1

Correct Answers:

0.8

Rationale :

👌 Step 1: Identify the prescribed dose

Prescribed dose 8,200 units

👌 Step 2: Identify the concentration from the vial

10,000 units per 1 mL

👌 Step 3: Use the volume–dose formula

Volume (mL)=Prescribed dose (units)/Concentration (units/mL)

8,200/10,000

👌 Step 4: Calculate volume

8,200/10,000

0.82

Rounded to 0.8 mL

Answer 3

Correct Answers:

5

Rationale :

💎Step 1: Convert weight from pounds to kilograms

44÷2.2=20 kg

💎 Step 2: Calculate the dose for Day 1

10 mg/kg×20 kg=200 mg

💎 Step 3: Use the volume–dose formula based on 200 mg/5 mL

Volume (mL)=Prescribed dose/Concentration ×Volume available

200/200×5

5 mL

Answer 4

Correct Answers:

50

Rationale :

📌 Step 1: Determine the current infusion concentration

20,000 units in 500 mL

Concentration=20,000/500

40 units/mL

📌 Step 2: Calculate current mL/hour rate

Current rate=1,800 units/hr/40 units/mL

45 mL/hr

📌 Step 3: Apply the prescribed increase

New rate=45+5

50 mL/hr

Correct Answers:

20

Rationale :

📝 Step 1: Determine the concentration of the IV solution

50 units of insulin in 100 mL

Concentration=50 units100 mL

0.5 units/mL

📝 Step 2: Use the formula to calculate mL/hour

mL/hr=Prescribed units/hr/Units per mL

Answer 6

Correct Answers:

0.1

Rationale :

✍️ Step 1: Convert available concentration to micrograms

1 mg = 1,000 mcg

So, 1 mg/mL = 1,000 mcg/mL

✍️ Step 2: Use the volume–dose formula

Volume (mL)=Prescribed dose (mcg)/Concentration (mcg/mL)

100/1000

✍️ Step 3: Calculate the volume

100/1000

0.1 mL

Answer 7

Correct Answers:

100

Rationale :

💎 Step 1: Identify total volume and infusion time

Volume = 150 mL

Time = 90 minutes

90/60

1.5 hours

💎 Step 2: Use the infusion rate formula

mL/hr=Total volume (mL)/Time (hr)

150/1.5

💎 Step 3: Calculate rate

150/1.5

100 mL/hr

Answer 8

Correct Answers:

1.5

Rationale :

🎯 Step 1: Convert prescribed dose to micrograms (mcg)

0.075 mg=75 mcg

🎯 Step 2: Use the dose–tablet formula

Tablet strength = 50 mcg

Tablets=75 mcg/50mcg/tablet

1.5 tablets

Correct Answers:

0.5

Rationale :

📌Step 1: Identify the prescribed dose

Prescribed = 5,000 units

📌 Step 2: Identify the available concentration

10,000 units per 1 mL

📌 Step 3: Use the volume–dose formula

Volume (mL)=Prescribed dose (units)/Concentration (units/mL)
