Correct Answer is C
Explanation
A. Auscultate the antecubital fossa using a Doppler stethoscope: The graft is located in the forearm, not the antecubital fossa.
B. Measure the client's blood pressure to ensure it is higher in the left arm than the right: This does not assess AV graft patency and blood pressure should be avoided in the arm with a graft.
C. Auscultate the site for a bruit: The presence of a bruit and thrill indicates blood flow through the graft, confirming patency.
D. Check the brachial and radial pulses of the left arm simultaneously: While peripheral pulses can offer some insight, they do not directly confirm graft patency.
Correct Answer is C
Explanation
A. Obtain a complete blood count (CBC): This is not the immediate action in an active bleeding scenario.
B. Start IV fluids: This may be needed later if significant blood loss occurs, but not the first response.
C. Apply direct pressure: Bleeding from a fistula requires immediate direct pressure to prevent blood loss and preserve vascular access.
D. Administer pain medication: Pain management is important but not the priority in acute bleeding.
