Describe three early signs of shock and the rationale for each. Solution shock is defined as an acute clinical syndrome characterized by hypoperfusion and severe dysfunction of vital organs. it is a result of circulatory collapse. early signs/first signs paleness: and excessive sweating due to reduced blood supply to perpheries like skin due to perpheral pooling of blood ( moves into central circulation) weak wide pulse due to initially due to increase adrenaline release and subsequent peripheral vasoconstriction and increased diastolic pressure tachycardia due to more work of heart . in shock vital organs need blood supply to survice so heart work more to maintain the perfusion to vital organs dilated pupils due to sympathetic stimulation increased breathing frequency ( tachypnea) due to more wok of lung to compensate metabolic disturbence ( production of more co2 to which lung work more to send out and provide more oxygen to tissue aganist muscle impairment.
