Ans:_THE WORKING CONDITION OF HIS HEART VIA ECG AND CORONARY CIRCULATION_VIA ANGIOGRAPHY ____________________________________________________________________ What are the appropriate health assessment skills for this client? Ans:_ECG AND ANGIOGRAPHY _____________________________________________________________________ What are the common patterns of reaction to stress? Ans:_INCREASED ADRENALINE SECRETION ,INCREASED HR ,DUE TO OLD AGE ARTERIOSCLEROSIS,THEREFORE INCREASES BLOOD PRESSSURE _____________________________________________________________________ Why is the wife so worried?
