Answer 3

Correct Answers:

1250

Rationale :

🟣Prescription: 300 mg/kg/24 hours, divided every 4 hours

🟣Child's weight: 55 lb

🟣Step 1: Convert pounds to kilograms:

55÷2.2

25 kg

🟣Step 2: Calculate total daily dose in mg:

300 mg/kg/day×25 kg=7,500 mg/day

🟣Step 3: Determine number of doses per day:

24/4

6 doses/day

🟣Step 4: Divide total daily dose by number of doses:

7500/6

1250 mg per dose

Answer 6

Correct Answers:

10.2

Rationale :

🔴Prescribed dose: 3 mcg/kg/min

🔴Client weight: 91 kg

🔴 IV solution concentration: 400 mg in 250 mL

🔴Note: 1 mg = 1,000 mcg

400 mg = 400,000 mcg

🔴 Step 1: Calculate total mcg/min needed:

3 mcg/kg/min×91 kg

273 mcg/min

🔴 Step 2: Calculate concentration in mcg/mL:

400,000 mcg/250 mL

1600 mcg/mL

🔴 Step 3: Calculate mL/min needed:

273 mcg/min/1600 mcg/mL

0.1706 mL/min

🔴 Step 4: Convert mL/min to mL/hr:

0.1706×60

10.24 mL/hr

🔴 Step 5: Round to the nearest tenth:

10.2 mL/hr
