What is the electrolyte content of D51/2NS?

• A. Glucose: 50 g/L; Sodium: 77 mEq/L; Chloride: 77 mEq/L
• B. Glucose: 50 g/L; Sodium: 77 mEq/L; Chloride: 100 mEq/L
• C. Glucose: 25 g/L; Sodium: 77 mEq/L; Chloride: 77 mEq/L
• D. Glucose: 50 g/L; Sodium: 90 mEq/L; Chloride: 90 mEq/L

Answer: (A)

D51/2NS is 5% dextrose in half-strength saline, so it carries both the glucose from the dextrose and the electrolyte content of half-normal saline. The dextrose part provides 50 g/L of glucose. The half-normal saline provides about 77 mEq/L of sodium and 77 mEq/L of chloride. Therefore, the electrolyte content is glucose 50 g/L, sodium 77 mEq/L, chloride 77 mEq/L. This matches the option that lists those exact values. The other choices have incorrect glucose amounts or incorrect Na/Cl values for half-strength saline.
