Which abbreviation stands for Dextrose 5% in 1/2 normal saline?

Explanation:
Dextrose 5% in 1/2 normal saline is abbreviated as D5-1/2 NS because the notation shows both components: “D5” for 5% dextrose and “1/2 NS” for half-normal saline (0.45% NaCl). This combination provides calories from glucose while delivering a lower salt concentration than normal saline. The other options describe different mixtures: D5NS is 5% dextrose in normal saline (0.9% NaCl), D5W is dextrose 5% in water (no saline), and NS is plain normal saline without dextrose.
