Review ATI Fluid Electrolyte and Acid-Base Regulation related questions and content

You are caring for a 65-year-old male patient admitted to your medical unit 72 hours ago with pyloric stenosis. A
nasogastric tube placed upon admission has been on low intermittent suction ever since. Upon review of the mornings
blood work, you notice that the patients potassium is below reference range. You should recognize that the patient may
be at risk for what imbalance?

  • A. Hypercalcemia
  • B. Metabolic acidosis
  • C. Metabolic alkalosis
  • D. Respiratory acidosis
Correct Answer: C

Rationale: The correct answer is C: Metabolic alkalosis. Pyloric stenosis can lead to vomiting, causing loss of gastric acid and chloride ions, leading to metabolic alkalosis. Low potassium levels are common in metabolic alkalosis due to potassium shifting into cells to compensate for the alkalosis. Hypercalcemia (choice A) is not associated with pyloric stenosis. Metabolic acidosis (choice B) typically presents with low pH and bicarbonate levels. Respiratory acidosis (choice D) is caused by impaired gas exchange in the lungs, not related to pyloric stenosis.
