Zorluk: OrtaPharmacological Therapies

A practical nurse (PN) is assigned to a client in a neurological rehabilitation unit. The client has a new prescription for phenytoin 5 mg/kg/day5\text{ mg/kg/day} by mouth, to be given in two equally divided doses. The client's current weight is 176 lb176\text{ lb}. The facility pharmacy provides phenytoin oral suspension at a concentration of 125 mg/5 mL125\text{ mg}/5\text{ mL}. Which of the following actions represents safe nursing practice by the PN?

  1. Verify the client's identity using two distinct identifiers and administer 8 mL8\text{ mL} of the oral medication per dose.Cevap
  2. B
    Bypass scanning the client's identification band prior to administration because the PN has cared for the client all week.
  3. C
    Calculate the individual dose using the client's weight in pounds, resulting in an administration of 17.6 mL17.6\text{ mL} per dose.
  4. D
    Accept a delegated task from the registered nurse to administer a supplemental dose of the medication via intravenous (IV) push.

Cevap

The correct action is to verify the client's identity using two distinct identifiers and to administer 8 mL8\text{ mL} of the oral medication per dose.
The practical nurse must verify the client's identity using two distinct identifiers prior to administration to ensure patient safety. Furthermore, the dose is accurately derived by converting the weight to kilograms (176 lb÷2.2=80 kg176\text{ lb} \div 2.2 = 80\text{ kg}), finding the single dose (400 mg/day÷2=200 mg/dose400\text{ mg/day} \div 2 = 200\text{ mg/dose}), and calculating the required liquid volume ((200 mg÷125 mg)×5 mL=8 mL(200\text{ mg} \div 125\text{ mg}) \times 5\text{ mL} = 8\text{ mL}).

Adım Adım Çözüm

1
Convert the client's weight from pounds to kilograms.
176 lb÷2.2=80 kg176\text{ lb} \div 2.2 = 80\text{ kg}
Standard medical dosages are calculated using the metric system.
2
Calculate the total daily dose based on the client's weight in kilograms.
80 kg×5 mg/kg=400 mg/day80\text{ kg} \times 5\text{ mg/kg} = 400\text{ mg/day}
The provider's prescription specifies the total amount to be given over 24 hours.
3
Determine the amount of medication required for a single dose.
400 mg÷2=200 mg/dose400\text{ mg} \div 2 = 200\text{ mg/dose}
The total daily medication is prescribed to be given in two equally divided doses.
4
Calculate the liquid volume to administer per dose using the pharmacy concentration.
(200 mg÷125 mg)×5 mL=8 mL(200\text{ mg} \div 125\text{ mg}) \times 5\text{ mL} = 8\text{ mL}
Using the 'Desired over Have times Volume' formula determines the exact milliliters needed for administration.
5
Identify the proper safety procedure for medication administration.
Verify two distinct patient identifiers.
Standard safety protocols mandate verifying identity before giving any medication to prevent administration errors.

Anahtar Kavram

Safe medication administration encompasses accurate weight-based dosage calculation, strict adherence to medication rights, and practicing within the established legal scope.
