Correct Answer is B
Explanation
A. White Blood Cell decrease
Platelet transfusions do not affect WBC levels. WBCs may change in response to infection or inflammation, but this is not an indicator of successful platelet transfusion.
B. Platelets increase
The primary goal of platelet transfusion is to increase platelet count to reduce bleeding risk in thrombocytopenia.
C. Hemoglobin increase
Hemoglobin levels increase after red blood cell (RBC) transfusions, not platelet transfusions.
D. PT and INR normalize
PT/INR measures clotting function, which is affected by clotting factors, not platelets. Platelet transfusions do not directly correct prolonged PT/INR.
Correct Answer is C
Explanation
A. Monitoring for dysrhythmias
While cardiovascular health is important, dysrhythmias are not a primary concern in a small abdominal aortic aneurysm.
B. Monitoring for bleeding
While aneurysms can rupture, a small aneurysm is managed medically with blood pressure control, making bleeding less of an immediate concern.
C. Adherence to their antihypertensive drugs
Hypertension increases pressure on the aneurysm, increasing the risk of expansion and rupture. Strict adherence to antihypertensive medications is essential for preventing complications.
D. Preventing thrombus formation
While thrombus formation can occur in large aneurysms, it is not the primary focus in a small, medically managed aneurysm.
