Answer to Question 1

Ans: C
Feedback:
The patient has developed drug tolerance and has to be administered an increased dosage of the drug to achieve the desired effect. Cumulative drug effect occurs when the body is unable to metabolize and excrete one (normal) dose of a drug before the next dose is given. Drug idiosyncrasy is a term used to describe any unusual or abnormal reaction to a drug. Toxic reactions are caused when blood concentration levels exceed the therapeutic levels of a drug.

Answer to Question 2

Ans: B
Feedback:
The nurse should monitor the patient's blood level of the drug to ensure that the level remains within the therapeutic range. Monitoring seizure activity, urination frequency, and blood pressure will not prevent toxicity. Seizure activity is unrelated to digoxin or heart failure.
