A client with rheumatoid arthritis receives a prescription for etanercept 25 mg. The medication is available in a prefilled syringe labeled, 50 mg/2 ml. How many ml should the nurse administer? (Enter the numerical value only.)
The Correct Answer is ["1.0"]
To calculate the volume of etanercept to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 25 mg / 50 mg/mL
Volume (mL) = 0.5 mL
Since the medication is available in a prefilled syringe labeled 50 mg/2 mL, we need to administer 2 mL to obtain the desired dose of 25 mg.
Therefore, the nurse should administer 1.0 mL of etanercept.

Correct Answer is B
Explanation
Step 1: Calculate the infant's weight in kilograms:
22 pounds x (1 kg / 2.20462 pounds) ≈ 10 kg
Step 2: Calculate the recommended maximum daily dose:
Recommended Maximum Dose = 3.5 mg/kg/day x 10 kg
Recommended Maximum Dose = 35 mg/day
Step 3: Calculate the prescribed daily dose:
Prescribed Daily Dose = 0.87 mg/dose x 4 doses/day
Prescribed Daily Dose = 3.48 mg/day
Step 4: Compare the prescribed dose to the recommended maximum dose:
The prescribed daily dose (3.48 mg/day) is slightly above the recommended maximum daily dose (35 mg/day).
Therefore, the nurse should:
B. Assess the child's heart rate before administration.
While the prescribed dose is slightly above the recommended maximum, it's important to monitor the child's heart rate to ensure there are no adverse effects. If the heart rate is within the normal range, the medication can be administered. However, if there are any concerns, the nurse should consult with the health-care provider.

Calculation for 3/4 Strength Ensure Feeding
Prompt: To determine how many milliliters of full-strength Ensure to use to prepare a 3/4 strength feeding.
Given:
Desired volume of 3/4 strength Ensure: 275 mL
Strength required: 3/4
Formula:
Amount of full-strength Ensure = Total volume x Strength required
Calculation:
Amount of full-strength Ensure = 275 mL x (3/4)
Amount of full-strength Ensure = (275 x 3) / 4
Amount of full-strength Ensure = 825 / 4
Amount of full-strength Ensure = 206.25 mL
Rounding to the nearest whole number:
Amount of full-strength Ensure = 206 mL
Therefore, the nurse should use 206 mL of full-strength Ensure to prepare the feeding.
