A healthcare provider prescribes haloperidol 3 mg3 \text{ mg} intramuscularly (IM) for a client experiencing severe agitation. The pharmacy supplies a vial labeled haloperidol 5 mg/mL5 \text{ mg/mL}. How many mL\text{mL} should the nurse administer? (Record the answer using one decimal place.)

Cevap: 0.6 mL

Cevap

0.6
To determine the correct volume to administer, the nurse must divide the desired dose (3 mg3 \text{ mg}) by the available dose (5 mg5 \text{ mg}), and then multiply by the available volume (1 mL1 \text{ mL}). The calculation is (3÷5)×1=0.6 mL(3 \div 5) \times 1 = 0.6 \text{ mL}.

Adım Adım Çözüm

1
Identify the desired dose.
The desired dose is 3 mg3 \text{ mg}.
This is the specific amount of medication the provider prescribed.
2
Identify the available concentration.
The available concentration is 5 mg5 \text{ mg} per 1 mL1 \text{ mL}.
This is the strength of the medication supplied by the pharmacy.
3
Calculate the volume to administer.
3 mg5 mg×1 mL=0.6 mL\frac{3 \text{ mg}}{5 \text{ mg}} \times 1 \text{ mL} = 0.6 \text{ mL}.
Using dimensional analysis or the standard 'Desired over Have' formula determines the correct administration volume.
