- A. OTC drugs are serious medications and carry serious risks if not taken as directed.
- B. Taking medications like that is careless and you could kill yourself doing it.
- C. Sometimes you need to take more than the package directs to treat the symptoms.
- D. Did you notify your doctor of the increased dosage you were taking?
Correct Answer: A
Rationale: OTC drugs are no less a medication than prescription drugs and carry the same types of risks for overdosage and toxicity if directions are not followed. Although increasing the dosage is careless and dangerous, it is important to use the information as a teaching opportunity rather than scolding the patient. Agreeing with the patient or asking her if she talked to the doctor misses the teaching opportunity, which could be harmful for the patient.

- C. Apple juice
- D. Orange juice
Correct Answer: D
Rationale: Vitamin C increases the absorption of iron by the body. The mother should be instructed to administer the medication with a citrus fruit or a juice that is high in vitamin C. Milk may affect absorption of the iron. Water will not assist in absorption. Orange juice contains a greater amount of vitamin C than apple juice.
