The answer to this is A. This type of intervention will be highly effective in the removal of the secretions and gases. This can be effective in lowering the arterial oxygen saturation which is the main goal. If case B would be the option, this will only maintain the arterial oxygen saturation. There are even times when it would be raised.
A cooling blanket will not have any effect on the sao2 levels which is considered to be important. Letter D can be a bit tricky to use and would require the diagnosis and intervention of the physician to ensure that this will be safe to do.
Endotracheal suctioning-rationale: endotracheal suctioning removes secretions as well as gases from the airway and lowers the arterial oxygen saturation (sao2) level. coughing and using an incentive spirometer improve oxygenation and should raise or maintain oxygen saturation. because of superficial vasoconstriction, using a cooling blanket can lower peripheral oxygen saturation readings, but sao2 levels wouldnt be affected.client needs category: physiological integrityclient needs subcategory: reduction of risk potentialcognitive level: comprehensionreference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 740.
