Correct Answer is B
Explanation
Choice A rationale:
Bradycardia, or a slow heart rate, is not typically an early sign of circulatory overload.
Choice B rationale:
Dyspnea, or difficulty breathing, is an early sign of circulatory overload. This occurs because the heart is unable to pump the excess blood effectively, leading to fluid buildup in the lungs.
Choice C rationale:
Flushing, or reddening of the skin, is not typically an early sign of circulatory overload.
Choice D rationale:
Vomiting is not typically an early sign of circulatory overload.
Correct Answer is B
Explanation
Choice A rationale:
Metabolic alkalosis is incorrect because it would present with a high pH and high HCO3. This client’s pH is low, indicating acidosis, not alkalosis.
Choice B rationale:
Respiratory acidosis is correct. It is characterized by a low pH and high PaCO2, as seen in this client’s results. This condition occurs when the lungs can’t remove enough CO2, causing it to build up in the blood and lower the pH.
Choice C rationale:
Metabolic acidosis is incorrect because it would present with a low pH and low HCO3. This client’s HCO3 is normal.
Choice D rationale:
Respiratory alkalosis is incorrect because it would present with a high pH and low PaCO2. This client’s pH is low and PaCO2 is high.
