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

Answer and Explanation

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.

Explanation

Marfan syndrome is a genetic disorder that affects the connective tissue, causing problems with the heart, blood vessels, eyes, bones, and joints. It is caused by a mutation in the FBN1 gene, which encodes for a protein called fibrillin-1. Marfan syndrome follows an autosomal dominant pattern of inheritance, which means that only one copy of the mutated gene is needed to cause the disorder. A person with Marfan syndrome has a 50% chance of passing on the mutated gene to each child, regardless of the gender of the parent or the child.
