In a hospitalized patient with community-acquired pneumonia, when should IV fluids be given?

• A. In all patients
• B. If hypotensive
• C. Only if dehydration
• D. Only if WBC high

Answer: (B)

The key idea is that IV fluids are used for resuscitation only when there is impaired perfusion. In a hospitalized patient with community-acquired pneumonia, fluids should be given if there is hypotension because low blood pressure signals inadequate tissue perfusion (shock), and restoring intravascular volume helps improve perfusion and stabilize the patient. If the patient is not hypotensive, fluids aren’t automatically required just because of pneumonia; giving fluids without a perfusion deficit risks fluid overload. WBC count doesn’t guide fluid therapy, and dehydration alone isn’t the universal trigger—though dehydration may be treated with fluids if it contributes to hypotension. So the appropriate trigger for IV fluids here is hypotension.
