A patient arrives at the emergency department with abdominal pain, nausea, and vomiting. A physical examination reveals acute pain at the McBurney point. A CT scan confirms the diagnosis, and surgery is immediately scheduled to prevent peritonitis. Based on this information, which diagnosis is described?
Inguinal hernia
Gastroenteritis
Cholelithiasis
Acute appendicitis
The Correct Answer is D
Acute appendicitis is an inflammation of the appendix, a small pouch attached to the large intestine that has no known function. It can cause abdominal pain that usually starts around the navel and then shifts to the lower right quadrant, nausea, vomiting, loss of appetite, fever, and constipation or diarrhea. The McBurney point is a spot located about two-thirds of the way from the navel to the right hip bone that is tender when pressed in patients with appendicitis. A CT scan can show signs of inflammation and enlargement of the appendix and rule out other causes of abdominal pain. Surgery (appendectomy) is the standard treatment for appendicitis to remove the inflamed appendix and prevent complications such as peritonitis (infection of the lining of the abdominal cavity) or abscess (collection of pus) formation.

Explanation
Naïve T cells are a type of white blood cell that has not encountered a specific antigen before and are ready to respond to new infections. As people age, the number of naïve T cells decreases due to the shrinking of the thymus gland, which produces and matures T cells. This reduces the ability of the immune system to recognize and fight new pathogens and lowers the effectiveness of vaccines.
Correct Answer is B
Explanation
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.
