A nurse is collecting data from a client who has peripheral arterial disease (PAD). Which of the following findings should the nurse expect?
Warm extremities.
Darkened skin color near extremities.
Intermittent claudication.
Edema.
The Correct Answer is C
Choice A rationale
Warm extremities are not typically associated with peripheral arterial disease (PAD). PAD usually results in reduced blood flow, leading to cooler extremities.
Choice B rationale
Darkened skin color near extremities is more commonly associated with venous insufficiency rather than PAD. PAD typically causes pale or bluish skin due to reduced blood flow.
Choice C rationale
Intermittent claudication, which is pain or cramping in the legs during exercise that subsides with rest, is a hallmark symptom of PAD. It occurs due to reduced blood flow to the muscles during activity.
Choice D rationale
Edema is more commonly associated with venous insufficiency or heart failure rather than PAD. PAD typically causes reduced blood flow, not fluid accumulation.

Correct Answer is C
Explanation
Choice A rationale
A serum creatinine test does not inform the provider about anemia. Anemia is typically diagnosed through a complete blood count (CBC) test, which measures the levels of hemoglobin and hematocrit in the blood.
Choice B rationale
A serum creatinine test does not provide information about infections. Infections are usually diagnosed through clinical evaluation and specific tests such as blood cultures, urine cultures, or imaging studies.
Choice C rationale
A serum creatinine test measures the level of creatinine in the blood, which is an indicator of kidney function. Elevated creatinine levels can indicate impaired kidney function or kidney disease.
Choice D rationale
A serum creatinine test does not provide information about thyroid disorders. Thyroid function is typically assessed through tests that measure levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood.
Correct Answer is C
Explanation
Choice A rationale
Metabolic acidosis is incorrect. Metabolic acidosis is characterized by a low pH and low HCO₃ levels. In this case, the HCO₃ level is normal, which rules out metabolic acidosis.
Choice B rationale
Metabolic alkalosis is incorrect. Metabolic alkalosis is characterized by a high pH and high HCO₃ levels. In this case, the pH is low, and the HCO₃ level is normal, which rules out metabolic alkalosis.
Choice C rationale
Respiratory acidosis is correct. Respiratory acidosis is characterized by a low pH and high PaCO₂ levels. In this case, the pH is 7.24 (low), and the PaCO₂ is 53 (high), indicating respiratory acidosis. This condition occurs when there is an accumulation of CO₂ in the blood due to inadequate ventilation.
Choice D rationale
Respiratory alkalosis is incorrect. Respiratory alkalosis is characterized by a high pH and low PaCO₂ levels. In this case, the pH is low, and the PaCO₂ is high, which rules out respiratory alkalosis.
