Final answer:
The treatment for dehydration caused by malignancy is fluid replacement therapy, using NaCl solution or a combination of isotonic saline and Na lactate given intravenously. This is essential to restore blood volume and correct electrolyte imbalances, but is separate from treatments targeting the cancer itself. Option 1.
Step-by-step explanation:
The treatment for dehydration caused by malignancy primarily involves fluid replacement therapy option 1. A standard solution like NaCl (sodium chloride) or a combination of isotonic saline and Na lactate may be given parenterally, typically intravenously, to address both fluid and electrolyte losses. This type of treatment supports the physiological need to restore adequate blood volume and maintain normal cellular function.
While cancer treatments such as surgery, chemotherapy, and radiation therapy target the malignancy itself, they are not direct treatments for dehydration. In scenarios where dehydration is a complication of malignancy or its treatment, such as through the effects of chemotherapy, managing hydration status is crucial for patient care.
It's important to note that in certain cases, like diabetes mellitus or Addison's disease among others, dehydration might not be effectively corrected by conventional methods and may require specific treatment approaches to address the underlying condition.
