In shock one should preferably not use–

Correct option is C

Sol. In shock, the goal is rapid volume replacement using isotonic fluids like Normal Saline or Ringer Lactate. Dextrose 5% (D5W) is a hypotonic solution once glucose is metabolized, and it does not effectively expand intravascular volume, making it unsuitable for resuscitation. It may worsen hypotension and is avoided in shock management.
Explanation of each option:
· (a) Normal saline – Isotonic fluid of choice for initial shock treatment; restores circulating volume and blood pressure.
· (b) Dextrose Normal saline – Has both volume and energy components; may be used in some cases but not preferred as first-line.
· (c) Dextrose 5% – Correct Answer. Provides calories but not effective plasma expansion. Not suitable in hypovolemic or septic shock.
· (d) Ringer lactate – Isotonic and physiologically balanced fluid; ideal for shock due to its composition resembling plasma.
