Final answer:
The nurse should frequently check the client's pedal pulses to ensure limb circulation post renal angiography via a femoral puncture.
Step-by-step explanation:
When providing postprocedure care to a client recovering from renal angiography where a femoral puncture site was used, the nurse should check the client's pedal pulses frequently. This is because monitoring the pedal pulses can help ensure that the circulation to the affected limb remains intact. Keeping the client's knee bent for extended periods or removing the dressing prematurely are not recommended because they can increase the risk of bleeding or infection. Direct pressure to the puncture site is usually applied immediately after the procedure, not 30 minutes later, to ensure hemostasis.
