Which strategy can help prevent acute kidney injury?

1. Avoiding dehydration

2. Limiting antibiotic use only

3. Fluid resuscitation only

4. There are no strategies to prevent acute kidney injury

The correct answer is: Avoiding dehydration

Avoiding dehydration is a fundamental strategy for preventing acute kidney injury (AKI). Dehydration reduces blood flow to the kidneys, leading to a decreased ability to filter waste products and maintain electrolyte balance. When the body is dehydrated, the kidneys can be compromised, thus increasing the risk for AKI. Ensuring adequate hydration helps maintain perfusion to the kidneys, supporting their function and mitigating the risk of injury. Proper hydration is particularly important in situations such as surgeries, severe illness, or during the administration of certain medications that can stress the kidneys. By maintaining fluid balance, healthcare providers can help protect renal function and promote more favorable outcomes for patients at risk for AKI. The other strategies mentioned, such as limiting antibiotic use, are not specific preventative measures for AKI, and fluid resuscitation alone does not encompass the broader approach needed to prevent dehydration-related injuries.
