Question

A nurse is preparing to administer cefadroxil oral suspension 15 mg/kg PO for one dose to a client who weighs 98 lb. Available is cefadroxil 250 mg/5 ml. How many mL will be administered? Round to the nearest tenth.

Answer 1

Correct Answers:

13.4

Rationale :

⚖️First, convert weight in pounds to kilograms: 98 lb ÷ 2.2 = 44.5 kg.

🧪Next, calculate required dose: 15 mg × 44.5 kg = 667.5 mg.

💊Use the concentration: 250 mg/5 mL → 667.5 mg ÷ 250 mg = 2.67

💁‍♂️2.67 × 5 mL = 13.35 mL, rounded to the nearest tenth = 13.4 mL.

📌Core Message

Convert weight to kilograms, then use the medication concentration to solve for mL required.

Answer 2

Correct Answers:

24

Rationale :

💉Available concentration: 25,000 units in 500 mL → 25,000 ÷ 500 = 50 units/mL.

💊Required dose: 1,200 units/hr ÷ 50 units/mL = 24 mL/hr.

🧮Always calculate the units per mL first when using IV infusion pumps.

⚠️Ensure all units align properly before doing your final division.

📌Core Message

To find mL/hr for an IV infusion, divide prescribed dose by the concentration per mL.

Answer 3

Correct Answers:

12.625

Rationale :

💁‍♂️62 ÷ 4 = 15.5

🤝23 ÷ 8 = 2.875

💪15.5 – 2.875 = 12.625

📌Core Message

Convert fractions to decimals for accurate subtraction of unlike denominators.

Answer 4

Correct Answers:

False

Rationale :

🔄Convert to a common denominator:

💁‍♂️89/10 = 267/30

👉32/3 = 320/30

🤝267 – 320 = –53/30, not 57/30

🧠Therefore, the equation is incorrect and the answer is false.

📌Core Message

Ensure fraction subtraction is accurate by converting to a common denominator and checking the result.

Answer 5

Correct Answers:

37.2

Rationale :

🌡️Use the formula: (F − 32) × 5 ÷ 9

📉(98.9 − 32) × 5 ÷ 9 = 66.9 × 5 ÷ 9 = 37.166

💁‍♂️Rounded to the tenth = 37.2°C

📌Core Message

Use the formula (F−32) × 5 ÷ 9 to convert Fahrenheit to Celsius accurately.

Answer 6

Correct Answers:

0.5

Rationale :

💊Ordered: 500 mcg = 0.5 mg

📦Available: 1 mg scored tablet

📏0.5 mg ÷ 1 mg = 0.5 tablet

✂️Since the tablet is scored, it is safe to split.

📌Core Message

When converting mcg to mg, divide by 1,000 and compare to the tablet dosage to find the correct tablet fraction.

Answer 7

Correct Answers:

3

Rationale :

💊Ordered dose is 600 mg and available tablets are 200 mg each.

➗600 ÷ 200 = 3, so the client needs 3 full tablets.

⚠️Since the tablets are unscored, they cannot be safely split, but in this case no splitting is needed.

🧠This ensures the full prescribed dose is administered without altering the tablet.

📌Core Message

Divide the ordered dose by the tablet strength to find how many whole tablets to give.

Answer 8

Correct Answers:

24

Rationale :

💧One dose = 1.25 tablespoons.

➗30 ÷ 1.25 = 24 doses available.

🧮This involves basic division using decimals to find total doses.

📏Accurate calculation ensures proper dose tracking and supply estimation.

📌Core Message

Use decimal conversion to divide total volume by dose volume and determine available doses.

Answer 9

Correct Answers:

1.5

Rationale :

💉Reconstituted concentration = 100 mg/mL.

🧮150 mg ÷ 100 mg/mL = 1.5 mL.

⚖️This ensures correct volume is drawn to match the prescribed dose.

💊Rounding not needed since the value is exact to the nearest tenth.

📌Core Message

Calculate volume by dividing ordered milligrams by the mg/mL concentration.

Answer 10

Correct Answers:

Convert the client's weight to kilograms.

Rationale :

⚖️All medication dosages in pediatrics and weight-based meds are calculated in kg, not lb.

💊You must first convert weight to kg to get accurate dose in mg/kg.

💁‍♂️98 lb ÷ 2.2 = 44.5 kg, which is used in all subsequent calculations.

📏This ensures safe and precise dosing for weight-based meds.

📌Core Message

Always convert pounds to kilograms first when calculating weight-based medication doses.
