Fluid overload in a patient may cause

Correct option is C

Fluid overload can lead to increased hydrostatic pressure in the pulmonary circulation, causing pulmonary edema, where fluid leaks into the alveolar spaces. This results in breathlessness, crackles, and potentially life-threatening respiratory compromise.
Explanation of each option: • (a) Angioedema – Typically allergic or hereditary in origin; involves localized swelling of the face or airway, not directly related to fluid overload. • (b) Peripheral edema – While this can also occur with fluid overload, it is not as acute or dangerous as pulmonary edema. • (c) Pulmonary edema – Correct. It is a primary and dangerous complication of fluid overload, especially in heart failure or renal failure patients. • (d) Cerebral edema – Generally caused by trauma, infection, or electrolyte imbalance (e.g., hyponatremia), not fluid overload alone.
