A pediatric client weighing 44 lb44\text{ lb} (20 kg20\text{ kg}) has a new prescription for phenytoin oral suspension at 5 mg/kg/day5\text{ mg/kg/day} divided into two equal doses. The unit's medication supply contains phenytoin at a concentration of 125 mg/5 mL125\text{ mg}/5\text{ mL}. When retrieving and delivering this medication, which action by the practical nurse (PN) represents safe pharmacological practice?

  1. Draw up 2.0 mL2.0\text{ mL} into an oral syringe and confirm the client's identity using their name and date of birth.Cevap
  2. B
    Measure 4.0 mL4.0\text{ mL} of the suspension to provide the client's entire daily dosage requirement in one administration.
  3. C
    Check the medication label against the MAR three times and use the client's bed number for identification to prevent sleep interruption.
  4. D
    Ask an unlicensed assistive personnel (UAP) to independently recalculate the medication dosage prior to entering the client's room.

Cevap

The correct action is to draw up 2.0 mL of the medication and verify the client using their name and date of birth.
Administering 2.0 mL2.0\text{ mL} of phenytoin correctly delivers the required 50 mg50\text{ mg} individual dose. Furthermore, verifying the client using two acceptable identifiers (such as name and date of birth) complies with fundamental medication safety rights and scope of practice.

Adım Adım Çözüm

1
Calculate the total daily dose of phenytoin based on the client's weight.
20 kg×5 mg/kg/day=100 mg/day20\text{ kg} \times 5\text{ mg/kg/day} = 100\text{ mg/day}
The prescription is weight-based, so the total daily requirement must be established first.
2
Determine the amount required for a single dose.
100 mg÷2 doses=50 mg/dose100\text{ mg} \div 2\text{ doses} = 50\text{ mg/dose}
The prescription specifies that the daily dose is to be given in two equally divided doses.
3
Calculate the liquid volume needed to deliver the single dose using the supplied concentration (125 mg/5 mL125\text{ mg}/5\text{ mL}).
50 mg×(5 mL/125 mg)=2.0 mL50\text{ mg} \times (5\text{ mL} / 125\text{ mg}) = 2.0\text{ mL}
This converts the ordered milligram amount into a measurable milliliter volume.
4
Identify the standard safety requirements for medication administration.
Use two unique identifiers (e.g., name and date of birth).
Safe pharmacological practice prohibits using environmental markers like room or bed numbers to identify clients.
