A patient's blood gases show a pH of 7.53, PCO2 of 48, and HCO3 of 36 mEq/L. The nurse realizes that the acid-base disorder this patient is demonstrating is which of the following?
Respiratory Acidosis
Respiratory Alkalosis
Metabolic Alkalosis
Metabolic Acidosis
The Correct Answer is C
Choice A reason: Respiratory Acidosis is characterized by a low pH and a high PCO2, which is not the case here.
Choice B reason: Respiratory Alkalosis would involve a high pH and a low PCO2, which is not consistent with the patient's PCO2 level.
Choice C reason: Metabolic Alkalosis is indicated by a high pH and a high HCO3, which matches the patient's blood gas values.
Choice D reason: Metabolic Acidosis would show a low pH and a low HCO3, which is the opposite of this patient's presentation.

Choice C reason: Drinking fluids is generally encouraged but does not need to be reported unless it is restricted before the procedure.

Correct Answer is D
Explanation

Choice B reason: Poor nutrition can affect the overall health of individuals with COPD but is not a direct risk factor for developing the disease.
Choice C reason: Weight loss can occur in advanced stages of COPD due to increased energy expenditure from breathing difficulties, but it is not a risk factor for developing COPD.
Choice D reason: Increased risk for pneumonia is a direct risk associated with COPD, as the disease can compromise the respiratory system's ability to clear infections.
