which intervention will most likely lower the client’s arterial blood oxygen saturation?
A. Endotracheal suctioning B. Encouragement of coughing C. Use of cooling blanket D. Incentive spirometry ANS: A Endotracheal suctioning secretions as well as gases from the airway and lowers the arterial oxygen saturation (SaO2) level. Coughing and incentive spirometry 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 wouldn’t be affected. 61. A client with a solar burn of the chest, back, face, and arms is seen in urgent care. The nurse’s primary concern should be: A. fluid resuscitation B. infection C. body image D. pain management ANS: D With a superficial partial thickness burn such as a solar burn (sunburn), the nurse’s main concern is pain management. Fluid resuscitation and infection become concerns if the burn extends to the dermal and subcutaneous skin layers. Body image disturbance is a concern that has a lower priority than pain
