A nurse calculates the pediatric patient's medication dosage using Clark's rule and uses what formula?

A) Infant's age in months/150 months times the average adult dose
B) Child's age in years/child's age in years plus 12 times the average adult dose
C) Weight of child in pounds/150 pounds times the average adult dose
D) Surface area in square meters/1.73 times the average adult dose

Question 2

A patient presents at the clinic with signs and symptoms of seasonal allergic rhinitis. The patient is prescribed a nasal steroid to relieve symptoms.

Two days later, the patient calls the clinic and tells the nurse that he is frustrated and wants a new drug. What is the most appropriate response by the nurse? A) It may take up to 2 weeks to get the full clinical effect. Try to keep using the drug as ordered.
B) The drug must not work for you. Let's change to an oral steroid.
C) You probably are administering the drug incorrectly. Come in and we can review the process.
D) You probably need to try a different nasal steroid. This one should be effective by now.

Answer to Question 1

C
Feedback:
Clark's rule uses the child's weight to calculate the dose and assumes the adult dose is based on a 150-pound person. Fried's rule applies to a child younger than 1 year of age and assumes that an adult dose would be appropriate for a child who is 12.5 years (150 months) old. Young's rule applies to children 1 to 12 years of age. Surface area calculation of a child's dose is determined with the use of a nomogram including the child's height and weight.

Answer to Question 2

A
Feedback:
Nasal steroids require about 2 weeks to reach their full clinical effect so the patient should be encouraged to use the drug for that length of time before changing drugs or giving up. The other responses could be appropriate if after 2 weeks the patient is still not getting relief.
