The nurse is caring for a 3-year-old client who is two hours postoperative from a cardiac catheterization via the right femoral artery. Which assessment finding is an indication of arterial obstruction?
The pressure dressing at right femoral area is moist and oozing blood.
Pulse distal to the femoral artery is weaker on left foot than right foot.
Right foot is cool to the touch and appears pale and blanched.
Blood pressure trend is downward and pulse is rapid and irregular.
The Correct Answer is C
A. While bleeding can occur postoperatively from the catheter insertion site, it is more indicative of venous or capillary bleeding rather than arterial obstruction. Arterial obstruction typically presents with signs related to decreased arterial blood flow rather than external bleeding.
B. This finding suggests a difference in peripheral pulses between the two lower extremities. While it could indicate arterial compromise, the question specifically asks about arterial obstruction at the site of the catheterization (right femoral artery).
C. This finding is concerning for arterial obstruction. Coolness, pallor, and blanching of the right foot indicate decreased arterial blood flow to the extremity. Arterial obstruction can lead to reduced perfusion distal to the occlusion site, resulting in these clinical signs.
D. These vital sign changes could indicate systemic complications, such as shock, rather than isolated arterial obstruction at the femoral artery site. While systemic changes can occur secondary to arterial obstruction, they are not specific indicators of obstruction at the femoral artery.

Correct Answer is A
Explanation
Rationale
A. Osteoarthritis is characterized by the gradual destruction of joint cartilage. Cartilage serves as a cushion between the bones in a joint, and its deterioration leads to pain, stiffness, and reduced joint function. As the cartilage wears away, bones may rub directly against each other, causing further pain and damage.

B. Osteoarthritis is primarily a degenerative condition rather than an inflammatory one. While mild inflammation can occur in OA, it is not as prominent as in autoimmune conditions like rheumatoid arthritis. In OA, inflammation is secondary to cartilage damage rather than a primary driver of the disease process.
C. Loss of bone mineral density is more characteristic of osteoporosis, a condition where bones become weak and brittle. Osteoporosis involves a decrease in bone mass throughout the skeleton, whereas osteoarthritis specifically targets the joints and affects cartilage rather than bone density.
D. An infectious process in the synovial fluid could indicate septic arthritis, which is characterized by infection in the joint space. This is typically associated with acute symptoms such as severe joint pain, swelling, warmth, and fever.
Correct Answer is D
Explanation
Rationale
A. The complement system is part of the immune response and can be activated in various conditions, including sepsis. However, activation of complement pathways does not directly cause DIC. Instead, in septic shock, the release of pro-inflammatory cytokines and tissue factor can trigger systemic coagulation activation, leading to DIC.
B. Inhibition of red blood cell production, such as in conditions like aplastic anemia or certain types of bone marrow disorders, does not directly cause DIC. DIC is primarily a disorder of excessive activation of clotting factors in response to underlying conditions like sepsis, trauma, or cancer.
C. Production of extra platelets, or thrombocytosis, is not the cause of DIC. Thrombocytosis can occur in response to various conditions, but DIC involves consumption of platelets due to widespread activation of clotting within the vasculature.
D. DIC is characterized by the widespread consumption and depletion of clotting factors and platelets as they are used up in the formation of microthrombi throughout the bloodstream. This depletion leads to an increased risk of bleeding due to insufficient clotting factors remaining to maintain hemostasis.
