Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C"}
Explanation
Critical to assess: A. Airway patency and signs of inhalation injury
Clients in enclosed-space fires are at high risk for inhalation injury, which can lead to airway edema and obstruction. This is the first priority.
Critical assessment finding: C. Singed nasal hairs and soot around the nares
These are hallmark signs of possible inhalation injury and may indicate airway compromise even before symptoms become severe.
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.
