Which abbreviation denotes a dextrose solution in 1/2 normal saline?

Explanation:
Understanding IV fluid abbreviations is the key. The wording tells you two things: how much dextrose is in the solution and what the saline strength is. Dextrose 5% in half-normal saline means 5 grams of dextrose per 100 mL with 0.45% NaCl. That matches the description “a dextrose solution in 1/2 normal saline.” The other options don’t fit this combination: D5W is 5% dextrose in water (no saline); D5NS is 5% dextrose in normal saline (0.9% NaCl); NS is plain normal saline with no dextrose.
