  2. B
    Scan the client's identification band and the medication barcode, then administer 1.21.2 mL of the suspension.
  3. C
    Ask the client to confirm their name and date of birth, then administer 4.24.2 mL of the suspension.
  4. D
    Confirm the client's identity by checking the room number and bed assignment, then administer 66 mL of the suspension.

Cevap

The practical nurse should verify the client's identity using their full name and date of birth, then administer 66 mL of the suspension.
Safe medication administration requires fulfilling all the 'rights' of medication administration. First, the practical nurse must calculate the correct dosage. Using the formula DesiredHave×Quantity\frac{\text{Desired}}{\text{Have}} \times \text{Quantity}, the calculation is 300 mg250 mg×5 mL=6 mL\frac{300 \text{ mg}}{250 \text{ mg}} \times 5 \text{ mL} = 6 \text{ mL}. Second, the nurse must verify the 'right client' using at least two distinct, acceptable identifiers. The client's full name and date of birth are standard, safe identifiers. Therefore, the option that combines the accurate 66 mL dose with these valid identifiers is the only safe and correct action.

Adım Adım Çözüm

1
Determine the correct medication dosage using the standard calculation formula: DesiredHave×Quantity\frac{\text{Desired}}{\text{Have}} \times \text{Quantity}.
300 mg250 mg×5 mL=1.2×5 mL=6 mL\frac{300 \text{ mg}}{250 \text{ mg}} \times 5 \text{ mL} = 1.2 \times 5 \text{ mL} = 6 \text{ mL}.
Accurate dose calculation is a critical component of the 'right dose' principle in medication administration.
2
Identify the proper method for verifying the right client before administration.
Select two acceptable patient identifiers, such as the client's full name, date of birth, or medical record number.
National patient safety standards strictly prohibit the use of room numbers or bed assignments to identify a client.

Anahtar Kavram
