Final answer:
Lactated Ringers (LR) is an isotonic solution that contains electrolytes and is commonly used in medical settings to replace fluids and electrolytes in patients who are dehydrated or have lost blood.
Step-by-step explanation:
Lactated Ringers (LR) is an isotonic solution that contains electrolytes. It does not contain glucose, lactate, or bicarbonate. Isotonic solutions have the same concentration of solutes as the body fluids, which helps maintain the balance of fluids and electrolytes in the body. LR is commonly used in medical settings to replace fluids and electrolytes in patients who are dehydrated or have lost blood.
