Final answer:
A nurse measuring a patient's jugular venous pressure at 3.5 inches would expect to find peripheral edema, which signifies fluid accumulation in the extremities often associated with elevated JVP.
Step-by-step explanation:
The question pertains to the measurement and implications of jugular venous pressure (JVP). A nurse determining that a patient's JVP is 3.5 inches would expect to find additional signs of elevated JVP, which can indicate an increased right atrial pressure and potentially right-sided heart failure. One common clinical manifestation associated with elevated JVP is peripheral edema, which is the accumulation of fluid in extremities due to impaired venous return.
