Correct Answer is ["0.5"]
Explanation
The nurse should administer 0.5 mL of epinephrine.
Step-by-Step Calculation
Understanding the Problem
Desired dose: 0.5 mg epinephrine
Available concentration: 1 mg/mL epinephrine
Setting Up the Equation
We can use the following formula:
Desired dose (mg) = Concentration (mg/mL) X Volume (mL)
We need to find the volume (mL).
Calculating the Volume
0.5 mg = 1 mg/mL X Volume (mL)
To isolate Volume, we divide both sides by 1 mg/mL:
Volume (mL) = 0.5 mg / (1 mg/mL)
Volume (mL) = 0.5 mL
The nurse should administer 0.5 mL of epinephrine.

1 gram = 1000 milligrams
0.3 grams = 0.3 X 1000 = 300 milligrams
The nurse should administer 300 mg of lithium.
