Question

A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 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.)

Answer 1

Correct Answers:

0.2

Rationale :

Formula:

Volume (mL) = Desired dose (mg) ÷ Available dose (mg/mL)

Substitute values:

2 mg ÷ 10 mg/mL = 0.2 mL

Final Answer:

0.2 mL

Answer 2

Correct Answers:

0.4

Rationale :

1️⃣ 📌 Convert grams to milligrams:

3 g × 1000 = 3000 mg

2️⃣ 📌 Formula:

Volume (mL) = Desired dose (mg) ÷ Available dose (mg/mL)

3️⃣ 📌 Find mg per mL:

3000 mg ÷ 5 mL = 600 mg/mL

4️⃣ 📌 Substitute values:

250 mg ÷ 600 mg/mL = 0.416 mL

5️⃣ 📌 Round to the nearest tenth:

0.416 ≈ 0.4 mL

Answer 3

Correct Answers:

15

Rationale :

1️⃣ 🧮 Divide total dose into two equal doses:

40 mEq ÷ 2 = 20 mEq per dose

2️⃣ 🧮 Formula:

Volume (mL) = Desired dose (mEq) ÷ Available dose (mEq/mL)

3️⃣ 🧮 Find mEq per mL:

6.7 mEq ÷ 5 mL = 1.34 mEq/mL

4️⃣ 🧮 Substitute values:

20 mEq ÷ 1.34 mEq/mL = 14.9 mL

5️⃣ 🧮 Round to the nearest whole number:

14.9 ≈ 15 mL

Answer 4

Correct Answers:

4

Rationale :

1️⃣ 🔹 Formula:

Volume (mL) = Desired dose (mg) ÷ Available dose (mg/mL)

2️⃣ 🔹 Substitute values:

40 mg ÷ 10 mg/mL = 4 mL

3️⃣ 🔹 Round to the nearest whole number:

Already a whole number = 4 mL

Answer 5

Correct Answers:

0.8

Rationale :

1️⃣ 🖍 Formula:

Volume (mL) = Desired dose (units) ÷ Available dose (units/mL)

2️⃣ 🖍 Substitute values:

3,800 units ÷ 5,000 units/mL = 0.76 mL

3️⃣ 🖍 Round to the nearest tenth:

0.76 ≈ 0.8 mL

Answer 6

Correct Answers:

675

Rationale :

1️⃣ 🟢 Convert pounds to kilograms:

198 lb ÷ 2.2 = 90 kg

2️⃣ 🟢 Calculate total daily dose:

15 mg × 90 kg = 1,350 mg/day

3️⃣ 🟢 Divide into 2 equal doses (every 12 hr):

1,350 mg ÷ 2 = 675 mg per dose

4️⃣ 🟢 Round to the nearest whole number:

Already a whole number = 675 mg

Answer 7

Correct Answers:

35

Rationale :

1️⃣ 🔵 Formula:

Rate (mL/hr) = Total volume (mL) ÷ Total time (hr)

2️⃣ 🔵 Substitute values:

840 mL ÷ 24 hr = 35 mL/hr

3️⃣ 🔵 Round to the nearest whole number:

Already a whole number = 35 mL/hr

Answer 8

Correct Answers:

0.6

Rationale :

1️⃣ 🔶 Formula:

Volume (mL) = Desired dose (mg) ÷ Available dose (mg/mL)

2️⃣ 🔶 Substitute values:

30 mg ÷ 50 mg/mL = 0.6 mL

3️⃣ 🔶 Round to the nearest tenth:

Already at one decimal place = 0.6 mL

Answer 9

Correct Answers:

5

Rationale :

1️⃣ ⭐ Formula:

Volume (mL) = Desired dose (mg) ÷ Available dose (mg/mL)

2️⃣ ⭐ Substitute values:

5 mg ÷ 1 mg/mL = 5 mL

3️⃣ ⭐ Round to the nearest whole number:

Already a whole number = 5 ml
