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: Taking immunosuppressive medications only when symptoms of rejection are noticed is incorrect. Immunosuppressive medications must be taken consistently as prescribed to prevent rejection, even when the patient feels well.

Choice B reason: Avoiding exercise for the first year after the transplant is not necessary. Patients are usually encouraged to engage in light to moderate exercise to promote overall health and recovery. The type and level of exercise should be discussed with the healthcare provider.

Choice C reason: Following the prescribed medication regimen exactly as directed is crucial for preventing organ rejection. Consistent use of immunosuppressive medications helps maintain the balance needed to prevent the immune system from attacking the transplanted organ.

Choice D reason: Taking herbal supplements to boost the immune system is incorrect. Patients with organ transplants need to suppress their immune system to prevent rejection. Herbal supplements can interact with immunosuppressive medications and are generally not recommended without consulting a healthcare provider.

A. Large, bulky stools B. Three formed stools in eight hours C. Streaks of blood present in the stool

Correct Answer is C

Explanation

Choice A reason: Large, bulky stools are not uncommon after a barium enema, as the barium can cause temporary changes in stool consistency and volume. This finding would not necessarily warrant immediate reporting to the healthcare provider unless there are other concerning symptoms.

Choice B reason: Three formed stools in eight hours may indicate increased bowel activity but is not an unusual finding after a barium enema. This would not typically be a cause for concern unless accompanied by other symptoms.

Choice C reason: Streaks of blood present in the stool is a concerning finding that should be reported to the healthcare provider. The presence of blood may indicate mucosal injury, inflammation, or other complications that need to be addressed promptly.
