Which of the following statements is true regarding the risks associated with hemodialysis?

The statement regarding the requirement for constant blood pressure monitoring during hemodialysis is accurate due to the inherent risks associated with the procedure. Hemodialysis involves the removal of waste products and excess fluid from the blood, which can lead to significant changes in blood volume and pressure. Patients may experience hypotension due to the rapid removal of fluid, especially in those who are sensitive or have underlying cardiovascular issues. Therefore, close monitoring of blood pressure is essential throughout the procedure to ensure patient safety and to manage any potential complications that may arise.

By contrast, the other statements are inaccurate. Hemodialysis does pose a risk for infection, particularly at the access site. It is not uniformly safe during pregnancy, as the risks and benefits must be carefully weighed for each individual patient. Finally, hemodialysis is not only harmful for patients with renal failure; risks can extend to other patient populations, especially those with additional comorbidities. These considerations highlight the complexity and the need for vigilant monitoring during hemodialysis sessions.
