Questions: 8. The primary health-care provider has ordered ampicillin for an 18-kg child with a respiratory and soft tissue infection. The drug label recommends PO (children <20 kg) 50 to 100 mg / kg / day in divided doses. Which daily dose is safe for the client? 1. 500 mg / day 2. 600 mg / day 3. 1,500 mg / day 4. 2,000 mg / day 9. A primary health-care provider has prescribed 200 mcg IV push (IVP) daily for a client weighing 60 kg. The drug label recommends 2.5 mcg / kg IV every 24 hours. What should the daily weight-based recommended dose (mcg) be for the client? Record your answer as a whole number. mcg 10. An 11-year-old client weighing 36 kg is to receive acetaminophen. The drug reference indicates PO (children 1 to 12 yr): 10 to 15 mg / kg / dose every 4 hr. What is the recommended total daily dosage range (mg) for the client?

To solve the questions, we need to apply the given dosage guidelines to the specific weights of the patients.

The primary health-care provider has ordered ampicillin for an 18-kg child. The recommended dosage is 50 to 100 mg/kg/day in divided doses.

1. Calculate the safe dosage range:

   • Minimum dose: \( 18 \, \text{kg} \times 50 \, \text{mg/kg/day} = 900 \, \text{mg/day} \)
   • Maximum dose: \( 18 \, \text{kg} \times 100 \, \text{mg/kg/day} = 1800 \, \text{mg/day} \)

2. Evaluate the options:

   • 500 mg/day: Below the minimum safe dose.
   • 600 mg/day: Below the minimum safe dose.
   • 1500 mg/day: Within the safe dose range.
   • 2000 mg/day: Above the maximum safe dose.

The answer is the third one (3): 1500 mg/day.

A primary health-care provider has prescribed 200 mcg IV push daily for a client weighing 60 kg. The recommended dosage is 2.5 mcg/kg every 24 hours.

1. Calculate the recommended dose:
   • \( 60 \, \text{kg} \times 2.5 \, \text{mcg/kg} = 150 \, \text{mcg} \)

The daily weight-based recommended dose is 150 mcg.

An 11-year-old client weighing 36 kg is to receive acetaminophen. The recommended dosage is 10 to 15 mg/kg/dose every 4 hours.

1. Calculate the dosage per dose:

   • Minimum dose: \( 36 \, \text{kg} \times 10 \, \text{mg/kg} = 360 \, \text{mg/dose} \)
   • Maximum dose: \( 36 \, \text{kg} \times 15 \, \text{mg/kg} = 540 \, \text{mg/dose} \)

2. Calculate the total daily dosage range (6 doses per day, as every 4 hours):

   • Minimum total daily dose: \( 360 \, \text{mg/dose} \times 6 = 2160 \, \text{mg/day} \)
   • Maximum total daily dose: \( 540 \, \text{mg/dose} \times 6 = 3240 \, \text{mg/day} \)

The recommended total daily dosage range is 2160 mg to 3240 mg.
