Answer to Question 1

C
Feedback:
The patient should take the medication with food to decrease GI adverse effects. The nurse would encourage the patient to increase fluid intake to flush the bladder and urinary tract frequently and decrease the opportunity for bacteria growth. Orange juice would be contraindicated because it could cause an alkaline rash and produce alkaline urine, which encourages bacterial growth. This drug is taken two to three times a day and not in a single dose at night.

Answer to Question 2

A
Feedback:
The body may develop a tolerance to some drugs over time. Tolerance may arise because of increased biotransformation of the drug, increased resistance to its effects, or other pharmacokinetic factors. When tolerance occurs, the amount of the drug no longer causes the same reaction. Therefore, increasingly larger doses are needed to achieve a therapeutic effect. Cumulative effect occurs when the drug is not properly eliminated and more of the drug is administered, resulting in toxic levels accumulating. Interactions occur when the drug reacts badly with another substance such as food, another drug, or an alternative or complementary therapy. Addiction is the psychological need for a substance.
