sorry i did not get a chance to check this soon after i posted. been busy studying for 2 tests. the patients admitting diagnosis was a-fib, he is still in the hospital s/p pericardial effusion and is still draining fluid. on the day of admission, was given amiodarone blous and then was on an amiodarone drip for 24 hours.. since then he has been in SR and and is taking amiodarone po daily. he is continuosly on 3L of oxygen and gets breathing treatments albuterol/atrovent every 6 hours. he has dyspnea only upon exertion when transferring to a chair, and denies any chest pain or shortness of breath. the nursing diagnosis i came up with is Activity Intolerance related to compromised oxygen transport system secondary to dysrhythmia/atrial fibrillation.
