A patient has a new onset of a left bundle branch block seen on a 12 lead ECG. Which of the following would be indicated for this patient?
1. increase oxygen
2. assist the patient to a right side lying position
3. evaluate for myocardial infarction
4. elevate the head of the bed up to 30 degree angle
3
Rationale: Treatment for a bundle branch block is not usually necessary unless it is a new onset. In this case the patient may be experiencing a myocardial infarction and should be evaluated. The patient may or may not need an increase in oxygen. The patient does not need to be moved to a right side lying position and does not need the head of the bed elevated to a 30 degree angle.
