another.11 The correct identificationof the precipitating events andthe immediate administration ofappropriate treatment are criticalfor a positive outcome in CHFpatients, because inappropriatetherapy initiated as a result of mis-diagnosis may result in deleteriouseffects. Hoffman and Reynolds10reported that adverse effects weremore common in misdiagnosedpatients. Untoward effects includ-ed 1) respiratory depression (withor without lethargy) in patientswho received morphine; 2)hypotension and bradycardia inpatients who received both mor-phine and nitroglycerin; and 3)arrhythmia associated with hypo-kalemia and hypotension in pa-tients who received furosemide.
