Quiz 15 :
Acute Respiratory Failure

D Repositioning the patient will facilitate mobilization of secretions.Elevating the head of bed is an intervention to prevent infection.Venous thromboembolism prophylaxis is ordered to prevent complications of immobility.Sedation is an intervention to manage anxiety,and administration of sedatives increases the risk for retained secretions.

A Patients with ARDS often have hypoxemia refractory to treatment.Surfactant levels are often diminished in ARDS.Compliance decreases in ARDS.In early ARDS,hyperventilation may occur along with respiratory alkalosis.

B Hypoventilation is common after overdose and results in impaired elimination of carbon dioxide and respiratory acidosis.The overdose depresses the respiratory drive,which results in hypoventilation,not hyperventilation.Hypoxemia is expected secondary to depressed respirations.
