Final answer:
The patient is suffering from hypochloremic, hypokalemic metabolic alkalosis due to bowel obstruction and gastric suctioning, which are causing losses of K, Cl, and acid. Metabolic alkalosis occurs from prolonged vomiting and medications. Treatment may include intravenous KCl for low potassium.
Step-by-step explanation:
The patient is experiencing hypochloremic, hypokalemic metabolic alkalosis as a result of bowel obstruction which leads to decreased uptake of potassium (K) and chloride (Cl), and gastric suctioning which involves the loss of K, Cl, and stomach acid. Metabolic alkalosis can result from the loss of hydrogen and chloride ions due to prolonged vomiting, with medications such as diuretics and antacids contributing if used in excess.
Furthermore, Cushing's syndrome or excessive administration of ACTH can result in hypochloremia alkalosis by causing elevated aldosterone levels, increasing potassium loss via urinary excretion. To address hypokalemia, clinicians may administer intravenous KCl to replenish potassium levels.
