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.
Correct Answer is ["150"]
Explanation
Answer
The nurse should identify that 0.15 g is equivalent to 150 mg of desipramine.
Step-by-Step Conversion
Understanding the Problem
We need to convert 0.15 grams (g) to milligrams (mg).
Conversion Factor
1 gram (g) = 1000 milligrams (mg)
Setting Up the Equation
0.15 g X (1000 mg / 1 g) = ? mg
Calculation
Multiply 0.15 by 1000:
0.15 X 1000 = 150 mg
The nurse should identify that 0.15 g is equivalent to 150 mg of desipramine.
