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 A
Explanation
Rationale:
A. Hypertonic solutions, like TPN with 25% dextrose, can irritate peripheral veins and cause phlebitis. Administering them through a central line allows rapid dilution in a large volume of blood, reducing vein irritation and promoting safe infusion.
B. Blood glucose monitoring is not dependent on the line type; it is done via peripheral blood samples.
C. The infusion rate is determined by the prescribed therapy, not by whether a central line is used.
D. Central lines do not decrease the risk of infection; in fact, they carry a higher risk of central line–associated bloodstream infections compared with peripheral lines.
Correct Answer is ["A","B","D"]
Explanation
Rationale:
A. Probiotics, such as yogurt with live cultures, can promote healthy gut flora and improve bowel regularity.
B. Physical activity stimulates peristalsis, helping prevent constipation, especially in clients who have reduced mobility postoperatively.
C. Low-fiber foods worsen constipation. Clients should consume high-fiber foods such as fruits, vegetables, and whole grains to promote bowel movements.
D. Adequate hydration softens stool and prevents fecal impaction, particularly important for clients taking opioid pain medications.
E. Drinking warm or hot liquids can actually help stimulate bowel movements. There is no need to avoid them.
