Correct Answer is D

Explanation

A. Raising hands above the head may not effectively improve gas exchange and could lead to discomfort in a client with dyspnea.
B. Laying down may not facilitate optimal breathing; instead, sitting upright is generally more effective.
C. Increasing the breathing rate can lead to hyperventilation and does not improve gas exchange.
D. Drawing air in through the nose and exhaling slowly through pursed lips helps maintain positive pressure in the airways, prevents airway collapse, and improves gas exchange by allowing for more effective expiration.

A. pH 7.30, PCO2 20 mm Hg, HCO3 22 mEq/L (22 mmol/L), PO2 85 mm Hg. B. pH 7.49, PCO2 45 mm Hg, HCO3 32 mEq/L (32 mmol/L), PO2 90 mm Hg. C. pH 7.46, PCO2 55 mm Hg, HCO3 36 mEq/L (36 mmol/L), PO2 95 mm Hg. D. pH 7.29, PCO2 35 mm Hg, HCO3 25 mEq/L (25 mmol/L), PO2 99 mm Hg.

Correct Answer is B

Explanation

A. This value indicates metabolic acidosis rather than alkalosis due to a low pH and normal HCO3.
B. This value is indicative of metabolic alkalosis as the pH is elevated (7.49), the HCO3 is elevated (32 mEq/L), and the PCO2 is within normal range, reflecting a compensatory response.
C. While the pH is slightly elevated, the high PCO2 suggests respiratory compensation, making it less consistent with primary metabolic alkalosis.
D. This value indicates metabolic acidosis due to a low pH and normal HCO3 levels, not alkalosis.
