A client has received a prescription for loratadine suspension, 10 mg to be taken orally once a day. The bottle is labeled as "Loratadine for Oral Suspension, USP 5 mg per 5 mL." How many teaspoons should the nurse instruct the client to take? (Please enter the numerical value only.)

Step 1: We need to find out how many mL contain 10 mg of loratadine. Since 5 mg of loratadine is in 5 mL, we can set up a proportion to find out how many mL contain 10 mg. So, 5 mg is to 5 mL as 10 mg is to X mL. This gives us the equation: (5 mg ÷ 5 mL) = (10 mg ÷ X mL) Step 2: Solving for X gives us X = (10 mg × 5 mL) ÷ 5 mg Step 3: Simplifying gives us X = 10 mL So, the client needs to take 10 mL of the loratadine suspension to get a dose of 10 mg. Now, we need to convert this volume in mL to teaspoons, using the conversion factor you provided (1 teaspoon = 5 mL). Step 4: We set up the conversion as follows: 10 mL × (1 tsp ÷ 5 mL) Step 5: Simplifying gives us 2 tsp So, the nurse should instruct the client to take 2 teaspoons of the loratadine suspension.
