a) Daily when not in use Explanation: Daily instillation of dilute heparin flush when a port is not in use will maintain the port. Continuous infusion maintains the patency of each port. Heparin flushes are used after each intermittent infusion. Heparin flushes are used after blood drawing in order to prevent clotting of blood within the port. Heparin flush of ports is not necessary if a line is to be discontinued. pg.1231
