Explanation
To calculate the volume (mL) needed to administer 300 mg of amiodarone using a concentration of 50 mg/mL, you can use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 300 mg, and the concentration is 50 mg/mL:
Volume (mL) = 300 mg / 50 mg/mL = 6 mL
So, the nurse should administer 6 mL of amiodarone.
Correct Answer is ["300"]
Explanation
To calculate how many milligrams (mg) of guaifenesin the client is taking with each dose, you can use the following steps:
Determine the volume of the client's dose. The client is taking 1 tablespoon (Tbsp) of guaifenesin oral solution.
1 Tbsp is approximately equal to 15 mL.
Determine the concentration of guaifenesin in the oral solution, which is 100 mg/5 mL.
Calculate the amount of guaifenesin in the client's dose:
Amount (mg) = (Volume of dose in mL / Concentration in mg/mL)
Amount (mg) = (15 mL / 5 mg/mL) = 3 doses of 100 mg each
So, the client is taking 300 mg of guaifenesin with each dose.
