What is one cause of hypomagnesemia?

A. Celiac disease: This is an autoimmune disorder unrelated to peptic ulcer disease.

B. Penetration of the gastric wall: A severe complication of peptic ulcer disease is the penetration of the ulcer through the gastric or duodenal wall into adjacent organs, leading to further inflammation and damage.

C. Hepatorenal syndrome: This is a severe complication of liver disease, not peptic ulcer disease.

D. Persistent bleeding: Peptic ulcers can cause persistent or recurrent gastrointestinal bleeding, which can lead to anemia or require emergency medical intervention.

E. Inflammatory bowel disease: This is a separate condition that includes Crohn's disease and ulcerative colitis.

F. Iron overload: This condition is unrelated to peptic ulcer disease and more associated with genetic disorders like hemochromatosis.

A. Preventing the absorption of sodium and potassium: This statement is incorrect because the respiratory system does not affect the absorption of sodium and potassium; it primarily influences the levels of carbon dioxide (CO2) in the blood.

B. Blocking the arterial walls from absorbing electrolytes: The respiratory system does not block electrolyte absorption through arterial walls. This is not a mechanism involved in acid-base balance.

C. Increasing ventilation to drop the H+ ion level: The respiratory system compensates for acidosis by increasing ventilation, which helps to expel more CO2 from the lungs, reducing the concentration of H+ ions and thus decreasing acidity.

D. Regulating the excretion or reabsorption of H+ and HCO3: This is the role of the renal system, not the respiratory system. The kidneys regulate acid-base balance by excreting or reabsorbing H+ and HCO3.
