Question

Quizplus · Accepted Answer

An asthma exacerbation is characterized by bronchoconstriction due to bronchospasm,edema,and inflammation of the airways.This increases the amount of work a patient must do to overcome the increase in airway resistance,thereby increasing the patient's work of breathing.A drug overdose causes hypercapnic respiratory failure but because of a reduced drive to breathe.Myasthenia gravis is a neuromuscular disease that may paralyze the ventilatory muscles,causing a patient to not be able to move air.A pulmonary embolism would increase dead space by blocking off perfusion to a part of the lung.This would cause acute hypoxemic respiratory failure.
