What intervention should be taken for angina?

The correct course of action for managing angina during hemodialysis is to reduce blood flow rate to 150. Angina, or chest pain due to reduced blood flow to the heart, can be exacerbated during dialysis due to shifts in fluid balance and blood pressure changes. By decreasing the blood flow rate, the hemodynamic stress on the heart is minimized, which can help relieve chest pain and improve the overall condition of the patient.

Adjusting the blood flow rate allows for a more controlled dialysis session, potentially reducing the patient’s workload and oxygen demand. Maintaining equilibrium in the patient's hemodynamics is crucial for those at risk of cardiovascular events, particularly during a dialysis session.

Other interventions, while relevant in different contexts, do not directly address the acute nature of angina caused by dialysis. For example, increasing the ultrafiltration rate or administering insulin may not be appropriate in this situation, as they can further strain the cardiovascular system. Monitoring respiratory rate does provide important information about the patient's status but does not directly intervene to alleviate the anginal symptoms.
