A practical nurse is caring for an adult client who was recently diagnosed with a respiratory tract infection. The healthcare provider prescribes oral azithromycin 0.5 g0.5\text{ g} to be administered once daily. The pharmacy dispenses a reconstituted oral suspension labeled 250 mg/5 mL250\text{ mg}/5\text{ mL}. How many milliliters (mL\text{mL}) should the nurse administer to the client for each dose?

  3. C

  4. D

Cevap

The nurse should administer 10 mL10\text{ mL} of the oral suspension per dose.
The correct dose is 10 mL10\text{ mL}. To determine this, the practical nurse must first convert the prescribed 0.5 g0.5\text{ g} to 500 mg500\text{ mg}. Using the standard formula of (Desired / Have) \times Volume, the equation becomes (500 mg/250 mg500\text{ mg} / 250\text{ mg}) \times 5\text{ mL}.Thissimplifiesto. This simplifies to 2 \times 5\text{ mL},whichequals, which equals 10\text{ mL}$.

Adım Adım Çözüm

1
Convert the prescribed dose from grams to milligrams to ensure units match the supplied medication.
0.5 g=500 mg0.5\text{ g} = 500\text{ mg}
Units of measurement must be identical before a dosage calculation can be accurately performed.
2
Set up the dosage calculation using the standard formula: (Desired dose / Available dose) x Volume.
(500 mg/250 mg500\text{ mg} / 250\text{ mg}) \times 5\text{ mL}$
This formula accounts for both the concentration of the medication and the volume of liquid it is suspended in.
3
Perform the division and multiplication to find the final volume to administer.
2×5 mL=10 mL2 \times 5\text{ mL} = 10\text{ mL}
Solving the equation provides the precise volume required to safely deliver the prescribed amount of medication.
