An unconscious patient who was transferred from surgery to the postanesthesia care unit (PACU) 15 minutes ago has an oxygen saturation of 89%. Which action should the nurse take first?
Increase the oxygen flowrate.
Elevate the patient's head on two pillows.
Suction the patient's mouth.
Perform the jaw-thrust maneuver.
The Correct Answer is A
A. The most appropriate first action would be to increase the oxygen flowrate to improve the patient's oxygen saturation levels. This intervention directly addresses the hypoxemia and can help prevent further complications related to low oxygen levels in the blood.
B. Elevating the patient's head can help improve ventilation and oxygenation. By raising the head, the patient's airway may become more patent, allowing for better airflow and oxygen exchange in the lungs. However, this should follow oxygenation.
C. Suctioning the patient's mouth aims to remove any secretions or obstructions that may be compromising the airway and contributing to the low oxygen saturation. However, this should follow oxygenation.
D. This maneuver can be helpful if the airway is obstructed by the tongue or soft tissues, potentially improving ventilation and oxygenation. However, this should follow oxygenation.

Correct Answer is D
Explanation
D. Atorvastatin is a statin medication used to lower cholesterol levels and reduce the risk of cardiovascular events. Statins, including atorvastatin, have been associated with an increased risk of rhabdomyolysis, particularly when used in high doses or in combination with other medications that can interact to increase statin levels in the blood.
A. There is no direct evidence to suggest that omeprazole increases the risk of rhabdomyolysis when used in combination with colchicine.
B. There is limited evidence to suggest that hydrochlorothiazide significantly increases the risk of rhabdomyolysis when used in combination with colchicine.
C. There is no direct evidence to suggest that carvedilol increases the risk of rhabdomyolysis when used in combination with colchicine.
Correct Answer is C
Explanation
C. Erythrocyte sedimentation rate (ESR) is a blood test that measures the rate at which red blood cells settle in a tube of blood over time. ESR levels are commonly elevated in inflammatory conditions such as RA.
A. Rheumatoid factor (RF) is an autoantibody commonly found in individuals with rheumatoid arthritis (RA). However, monitoring RF levels is not typically used to evaluate the effectiveness of aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) in managing RA symptoms.
B. ANA levels are not typically monitored to evaluate the effectiveness of aspirin or NSAIDs in managing RA symptoms.
D. Monitoring WBC count is important for assessing overall health and detecting infections but it is not specific to evaluating the effectiveness of aspirin or NSAIDs in managing RA symptoms.
