Which electrolyte imbalance is most commonly associated with refeeding syndrome?
Hypermagnesemia
Hypercalcemia
Hypophosphatemia
Hyponatremia
The Correct Answer is C
Rationale:
A. Magnesium levels may actually drop, not rise, during refeeding syndrome due to intracellular shifts.
B. Calcium levels are typically not elevated as a direct result of refeeding syndrome.
C. Refeeding syndrome occurs when malnourished patients receive rapid carbohydrate reintroduction, triggering insulin release. This drives phosphate, potassium, and magnesium into cells, with phosphate depletion being the hallmark and most clinically significant electrolyte disturbance. Hypophosphatemia can cause muscle weakness, respiratory failure, and cardiac dysfunction.
D. Sodium levels may fluctuate, but hyponatremia is not the primary concern in refeeding syndrome.

Correct Answer is D
Explanation
Rationale:
A. Used to visualize the upper gastrointestinal tract (esophagus, stomach, duodenum). It does not provide information about bowel obstruction in the large intestine.
B. Allows direct visualization of the colon mucosa but is not typically used initially in suspected acute bowel obstruction due to the risk of perforation.
C. Useful for evaluating gallbladder, liver, kidneys, and sometimes bowel, but it is less sensitive for detecting large bowel obstruction.
D. A plain abdominal X-ray (KUB) is often the first-line diagnostic study for suspected large bowel obstruction. It can show dilated bowel loops, air-fluid levels, and fecal loading, which correlate with the patient’s symptoms of bloating, distention, and relief after flatulence.
Correct Answer is C
Explanation
Rationale:
A. Baked potato is low in sodium if prepared without added salt, making it safe for a client on a diuretic.
B. Milkshake is generally safe unless it contains added sodium; in most cases, it is allowed.
C. Ham is high in sodium, which is contraindicated for a client taking bumetanide, a loop diuretic, as high sodium intake can counteract the diuretic effect and worsen fluid retention.
D. Stewed tomatoes can be included if unsalted; they are generally safe in moderation.
