Which of the following are signs of fluid overload in patients receiving IV therapy?

Signs of fluid overload in patients receiving intravenous (IV) therapy often manifest as swelling, which is indicative of edema due to the excess fluid in the body. This can occur in various parts of the body, particularly the extremities. Elevated blood pressure is also a common sign, as increased fluid volume can lead to increased pressure within the vascular system, placing additional strain on the heart and blood vessels.

These symptoms highlight the body's struggle to manage the extra fluid, which doesn't occur in the other options listed. For instance, weight loss and a decreased heart rate can indicate dehydration or other conditions unrelated to fluid overload. Increased urination and fever may suggest different issues, such as a response to infection rather than an overload of fluids. Similarly, skin rash and itchiness are more associated with allergic reactions or side effects of certain medications, rather than signs of fluid overload.

Thus, swelling and elevated blood pressure are critical indicators of fluid overload, making the correct answer clear in identifying this significant concern in IV therapy management.
