1. Question
For which common complication of myocardial infarction should the nurse monitor clients in the coronary care unit?
CorrectOption 1 is the correct answer:
Rationale: Myocardial infarction (MI) may cause increased irritability of tissue or interruption of normal transmission of impulses. Dysrhythmias occur in about 90% of clients after an MI. 2 Hypokalemia may result when clients are taking cardiac glycosides and diuretics; this is a complication associated with therapy, not a pathologic entity related to the MI itself. 3 Anaphylactic shock is caused by an allergic reaction, not by an MI. 4 Cardiac enlargement is a slow process, so it will not be evident in the coronary care unit.
