A patient with osteoarthritis is scheduled for a total knee arthroplasty. The nurse identifies that the surgery will be postponed if the patient experiences which condition?
Chronic joint inflammation
Pain
Infection
Immobility
The Correct Answer is C
A. Chronic joint inflammation is a common feature of osteoarthritis, but it does not necessarily preclude surgery. In fact, joint inflammation is often a reason for considering a total knee arthroplasty.
B. Pain is a typical symptom of osteoarthritis, but it is not a reason to postpone surgery. Pain management can be addressed during the perioperative period.
C. Infection is a critical factor that would delay surgery. If the patient has an active infection, particularly in the joint or surrounding tissues, the risk of spreading the infection during surgery is high, and the procedure would need to be postponed until the infection is resolved.
D. Immobility is a concern for postoperative recovery but does not typically delay surgery. Physical therapy and rehabilitation can address immobility after the procedure.

Correct Answer is C
Explanation
A. While aspirin has analgesic properties, it is not primarily used for pain relief in the case of myocardial infarction (MI). Its main role in MI is to reduce the risk of further clot formation.
B. Aspirin has anti-inflammatory properties, but in the case of MI, its primary role is not inflammation reduction but rather preventing platelet aggregation.
C. Aspirin acts as an antiplatelet aggregate, which is its key action in preventing the formation of blood clots. This is crucial for patients with a history of MI, as it helps reduce the risk of further clot-related events, such as a recurrent MI or stroke.
D. Aspirin does have antipyretic effects, but this is not the primary reason for its use in MI.
Correct Answer is C
Explanation
A. Troponin is not an enzyme that indicates damage to brain, heart, and skeletal muscle tissues. It is a protein specifically related to heart muscle injury. Therefore, this explanation is inaccurate.
B. Troponin is not a lipid, and it does not reflect the risk for coronary artery disease. It is a cardiac-specific protein released into the bloodstream when heart muscle cells are damaged, particularly during a myocardial infarction.
C. Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. It is a highly sensitive and specific marker for myocardial injury, making it a critical test for diagnosing a myocardial infarction.
D. Troponin is not involved in oxygen transport. Hemoglobin is the protein responsible for oxygen transport throughout the body, not troponin.
