Which respiratory finding is expected in an attempt to compensate for metabolic acidosis?
Hyperventilation leading to increased PaCO2
Hyperventilation leading to decreased PaCO2
Hypoventilation leading to decreased PaCO2
Hypoventilation leading to increased PaCO2
The Correct Answer is B
Metabolic acidosis is a condition where the blood's pH is lowered due to an excess of non-volatile acids in the body, such as lactic acid, ketoacids, or ingested acids. This can occur due to diabetes, kidney failure, diarrhea, or ingestion of toxins.
The body has several mechanisms to compensate for metabolic acidosis and restore the normal pH balance. One of them is to hyperventilate, which helps to remove CO2 from the body and reduce the formation of H2CO3.

Correct Answer is C
Explanation
Rhabdomyolysis is a condition that occurs when skeletal muscle tissue breaks down rapidly due to injury, infection, drug toxicity, or other causes. The breakdown of muscle releases myoglobin, a protein that carries oxygen in muscle cells, into the bloodstream. Myoglobin can damage the kidneys by clogging the renal tubules and causing acute kidney injury. Rhabdomyolysis can also cause electrolyte imbalances, muscle weakness, and compartment syndrome.
