What adverse effect may occur if a client does not receive sufficient fluids after receiving IV contrast?

When a client receives intravenous (IV) contrast media, it is essential that they remain adequately hydrated afterward. Insufficient fluid intake after the procedure can lead to dehydration. This occurs because contrast agents can have a diuretic effect, causing increased urine output. If the body does not receive enough fluids to compensate for this loss, the result can be a decrease in overall fluid levels, leading to dehydration.

Dehydration can cause various complications, including reduced kidney function, as the kidneys may struggle to process and filter the contrast agent without adequate hydration. This is particularly relevant in patients with pre-existing kidney conditions or those at risk for contrast-induced nephropathy. Ensuring sufficient fluid intake is crucial in helping to flush out the contrast material from the body and to maintain optimal kidney function.

While hypotension and bradycardia may occur due to other factors or complications, they are not direct consequences of insufficient fluid intake post-contrast. Hyperglycemia is also unrelated as it pertains to blood sugar levels rather than fluid status. Therefore, insufficient hydration after administering IV contrast primarily leads to dehydration, making this the correct choice.
