Answer and explanation
Step 1 is to determine the amount of medication in each mL of solution. This is done by dividing the total amount of medication in the solution (250 mg) by the total volume of the solution (5 mL). This gives us 50 mg/mL. Step 2 is to determine how many mL of solution are needed to administer 500 mg of medication. This is done by dividing the desired dose (500 mg) by the concentration of the medication (50 mg/mL). This gives us 10 mL.
Correct Answer is ["1.5 tabs."]
Explanation
Step 1 is to determine the amount of citalopram in milligrams that the nurse needs to administer, which is 30 mg. Step 2 is to calculate the number of tablets needed to deliver this dose. This is done by dividing the required dose by the strength of each tablet. So, (30 mg ÷ 20 mg/tab) = 1.5 tabs.
