A client receives a prescription for loratadine suspension of 10 mg by mouth once a day. The bottle is labeled "Loratadine for Oral Suspension, UPS 5 mg per 5 mL." How many teaspoons should the nurse instruct the client to take? (Enter numerical value only.)

To calculate the amount of loratadine suspension the client should take, we need to divide the prescribed dose by the concentration of the suspension and then convert from milliliters to teaspoons. The prescribed dose is 10 mg, the concentration of the suspension is 5 mg/5 mL, and one teaspoon is equal to 5 mL. Therefore, the amount of loratadine suspension is: (10 mg / 5 mg/5 mL) x 5 mL/teaspoon = 10 mL/teaspoon The nurse should instruct the client to take two teaspoons of loratadine suspension.
