The nurse is caring for a patient diagnosed with chronic obstructive pulmonary disease (COPD). Which lab results will the nurse expect to find to support this diagnosis?

pH 7.30, PaCO2 59, HCO3 30

pH 7.50, PaCO2 30, HCO3 24

pH 7.48, PaCO2 42, HCO3 29

pH 7.33, PaCO2 34, HCO3 18

Answer and Explanation

The Correct Answer is A

Choice A reason: The lab results pH 7.30, PaCO2 59, HCO3 30 indicate respiratory acidosis with partial compensation. This is a typical finding in patients with chronic obstructive pulmonary disease (COPD) due to chronic hypoventilation and CO2 retention. The elevated PaCO2 reflects respiratory acidosis, and the elevated HCO3 indicates renal compensation to maintain acid-base balance.

Choice B reason: The lab results pH 7.50, PaCO2 30, HCO3 24 indicate respiratory alkalosis. This is not typical for COPD, where respiratory acidosis is more common.

Choice C reason: The lab results pH 7.48, PaCO2 42, HCO3 29 indicate metabolic alkalosis with partial compensation, which is not consistent with the primary respiratory issues seen in COPD.

Choice D reason: The lab results pH 7.33, PaCO2 34, HCO3 18 indicate metabolic acidosis with partial compensation, which is not typical for COPD. COPD primarily causes respiratory acidosis due to CO2 retention.

Correct Answer is C

Explanation

Choice A reason: Platelet transfusions are typically reserved for patients with severe bleeding or extremely low platelet counts. They are not a standard treatment for managing ITP unless there is significant bleeding.

Choice B reason: Plasma albumin is not a treatment for ITP. It is used for other conditions such as hypovolemia and hypoalbuminemia but does not address the underlying immune-mediated destruction of platelets in ITP.

Choice C reason: Intravenous immunoglobulin (IVIG) is a treatment for ITP that helps increase platelet counts by modulating the immune system. It is often used in acute settings to manage severe thrombocytopenia and bleeding.

Choice D reason: Factor D is not related to the treatment of ITP. It is involved in the complement system, which is part of the immune response but does not directly address the platelet destruction seen in ITP.

A. Normal blood pressure, deep respirations B. Increased alertness, normal heart rhythm C. High urine specific gravity, normal temperature D. Blood glucose of 250 mg/dL, disorientation

Correct Answer is B

Explanation

Choice A reason: Normal blood pressure and deep respirations do not necessarily indicate that hyperosmolar hyperglycemic syndrome is resolving. Deep respirations, also known as Kussmaul respirations, can occur in response to severe hyperglycemia.

Choice B reason: Increased alertness and a normal heart rhythm suggest that the patient's neurological status and cardiovascular system are stabilizing, which are positive indicators that the treatment is effective in managing hyperosmolar hyperglycemic syndrome.

Choice C reason: High urine specific gravity and normal temperature do not directly indicate the effectiveness of treatment for hyperosmolar hyperglycemic syndrome. High urine specific gravity can result from dehydration.

Choice D reason: A blood glucose level of 250 mg/dL with disorientation still indicates poorly controlled hyperglycemia and ongoing metabolic disturbance, which means the treatment is not yet effective.
