Answer 1

For intravenous injections, the following solutions will be preferred:

(C) 0.9 % NaCl

- The medicines are delivered directly into the blood by the use of intravenous injections.

- To prevent any disbalance in the blood concentration, the solution of these injections must be isotonic with the blood.

- For this purpose, we use a 0.9 % NaCl solution as it is isotonic with the blood.
