B. True. The absence of ADH in neurogenic DI leads to excessive loss of very dilute urine (virtually water only).

C. True. Blood loss of this extent required transfusion.

D. False. Septic patients have leaky capillaries and large fluid shifts which need replacing with Na⁺ containing fluid.

E. False. DKA patients are depleted of both water and Na⁺ from the osmotic diuresis caused by hyperglycaemia. 0.9 % saline is the most appropriate initial fluid to use.
