For patients with cardiovascular disease, they are at risk for ___________ even if we are using a standard rate for a healthy animal.

For patients with cardiovascular disease, they are at risk for ___________ even if we are using a standard rate for a healthy animal.

• A. Fluid Overload
• B. Hypotension
• C. Arrhythmia
• D. Hypoxemia

Answer: (A)

In cardiovascular disease, the heart’s ability to handle extra volume is limited, so a maintenance fluid rate that would be appropriate for a healthy animal can still push the patient into fluid overload. The damaged heart may not increase stroke volume adequately to accommodate the added preload, leading to elevated venous pressures and pulmonary edema. That edema disrupts gas exchange, increasing the risk of hypoxemia, and can worsen overall hemodynamics. So, even with a standard rate, fluid overload is the most direct and likely risk in these patients. While hypotension, arrhythmias, or hypoxemia can occur in this population, the scenario specifically highlights the danger of excessive volume from a normal maintenance rate.
