Which of the following is a common pre-procedural requirement before catheterization?

Medication adjustment is an important pre-procedural requirement before catheterization. This process may involve temporarily discontinuing or altering certain medications that could affect the patient's coagulation status, kidney function, or overall response during and after the procedure. For instance, anticoagulants may need to be paused to reduce the risk of bleeding during catheterization, while medications related to heart failure must be managed to optimize hemodynamic stability.

While other options may seem relevant in certain contexts, they are not universally required prior to catheterization. For instance, water fasting might be necessary for certain procedures that require sedation but is not a standard requirement across the board. Similarly, psychological evaluations can be important but are generally not a routine part of pre-procedural requirements for catheterizations. Intensive hydration may be utilized in some cases to protect kidney function, particularly when contrast dye is used, but it is not a standard requirement for all patients. Hence, medication adjustment stands out as a common and critical prerequisite for ensuring patient safety and procedural effectiveness.
