Question

a client with rheumatoid arthritis receives a prescription for etanercept 50 mg weekly injection. the medication is available in a prefilled syringe labeled, 50 mg/ml. how many ml should the nurse administer? (enter the numerical value only. if rounding is required, round to the nearest whole number.)

Explanation:

Step1: Recall the formula for dosage calculation

The formula for calculating the volume (in mL) of a medication to administer is \( \text{Volume (mL)}=\frac{\text{Dose (mg)}}{\text{Concentration (mg/mL)}} \).

Step2: Substitute the given values

We are given that the dose (Dose) is 50 mg and the concentration (Concentration) is 50 mg/mL. Substituting these values into the formula, we get \( \text{Volume}=\frac{50\space\text{mg}}{50\space\text{mg/mL}} \).

Step3: Perform the calculation

Simplifying the expression \( \frac{50}{50}=1 \).
