A client with osteoarthritis is prescribed oral ibuprofen 600 mg600 \text{ mg} every 8 hours as needed for joint pain. The medication is available on the unit as an oral suspension with a concentration of 100 mg/5 mL100 \text{ mg} / 5 \text{ mL}.

  2. B
    1.2 mL1.2 \text{ mL}

  4. D

Cevap

The nurse should administer 30 mL30 \text{ mL} for a single dose.
To calculate the correct liquid dosage, the formula (Desired / Have) × Volume is used. The desired dose is 600 mg600 \text{ mg} and the available dose is 100 mg100 \text{ mg} in a volume of 5 mL5 \text{ mL}. Calculating 600100×5\frac{600}{100} \times 5 yields 30 mL30 \text{ mL}.

Adım Adım Çözüm

1
Identify the desired (prescribed) dose.
Desired dose = 600 mg600 \text{ mg}
This is the target amount of medication the provider ordered for the client.
2
Identify the dose you have available and its corresponding volume.
Have = 100 mg100 \text{ mg}, Volume = 5 mL5 \text{ mL}
This represents the concentration of the medication supplied by the pharmacy.
3
Apply the standard dosage formula: (Desired / Have) × Volume.
600 mg100 mg×5 mL=6×5 mL=30 mL\frac{600 \text{ mg}}{100 \text{ mg}} \times 5 \text{ mL} = 6 \times 5 \text{ mL} = 30 \text{ mL}
This determines the exact physical volume of liquid needed to deliver the prescribed milligrams of medication.
