A client is taking aspirin (ASA) and asks the nurse how long the anticoagulant effect of a single dose of aspirin can last. The nurse replies:
"The anticoagulant effect of a single dose of aspirin can last for as long as a month."
"The anticoagulant effect of a single dose of aspirin can last for as long as a day."
"The anticoagulant effect of a single dose of aspirin can last for as long as a week."
"The anticoagulant effect of a single dose of aspirin can last for as long as 12 hours."
The Correct Answer is C
A. "The anticoagulant effect of a single dose of aspirin can last for as long as a month." This statement is incorrect. While aspirin has antiplatelet effects that inhibit blood clot formation, its duration of action is not as long as a month. Aspirin irreversibly inhibits the enzyme cyclooxygenase (COX), thereby inhibiting platelet aggregation. However, the effects on platelet function are not permanent, and platelets turnover within a few days, thus the anticoagulant effect of a single dose of aspirin typically lasts for a shorter duration.
B. "The anticoagulant effect of a single dose of aspirin can last for as long as a day." Aspirin's primary effect is on platelets, not directly on overall blood clotting. It inhibits the COX enzyme, reducing the production of thromboxane A2, a chemical that promotes platelet aggregation. The initial inhibition of platelet function is strongest within the first 24 hours after taking aspirin. However, the affected platelets remain dysfunctional for their entire lifespan (around 7-10 days).
C. "The anticoagulant effect of a single dose of aspirin can last for as long as a week." This statement is correct. Aspirin's effect on platelets is due to its irreversible inhibition of the COX enzyme. Platelets have a lifespan of about 7-10 days. Once a platelet is affected by aspirin, it cannot regain its function. As your body continuously produces new platelets, the overall antiplatelet effect gradually diminishes over time.
D. "The anticoagulant effect of a single dose of aspirin can last for as long as 12 hours."
Rationale: This statement is partially correct. The antiplatelet effect of aspirin does not typically last as short as 12 hours. While the peak inhibition of platelet function occurs within hours after administration, the duration of action is longer due to the irreversible inhibition of COX-1. However, stating that it lasts exactly 12 hours may not be entirely accurate for all individuals, as the duration of action can vary depending on factors such as individual metabolism and dose.

Correct Answer is D
Explanation
A. Clotting at the incision site. Enoxaparin (Lovenox) is an anticoagulant medication used to prevent blood clots, particularly deep vein thrombosis (DVT) and pulmonary embolism (PE), which are common complications following orthopedic surgeries like knee replacement. Monitoring for clotting at the incision site is essential to ensure that the medication is effectively preventing excessive clot formation while also ensuring that the patient does not experience excessive bleeding.
B. Increased pain. While increased pain could be a concern postoperatively, particularly after a surgical procedure like knee replacement, it is not a specific monitoring parameter for enoxaparin administration. Pain management is typically addressed separately, and increased pain may indicate issues such as inadequate analgesia, surgical complications, or other factors unrelated to enoxaparin therapy.
C. Gingival hyperplasia. Gingival hyperplasia refers to an overgrowth of gum tissue and is not directly associated with enoxaparin therapy. This side effect is more commonly associated with certain medications such as phenytoin and cyclosporine rather than anticoagulants like enoxaparin. Monitoring for gingival hyperplasia would not be relevant in this context.
D. Signs and symptoms of bruising and bleeding. This is the correct answer. Enoxaparin is an anticoagulant medication, which increases the risk of bleeding. Therefore, monitoring for signs and symptoms of bruising and bleeding is crucial to detect any potential complications such as hemorrhage or hematoma formation. This includes assessing for unusual bruising, bleeding from the gums, nosebleeds, hematuria, melena, or any other signs of internal or external bleeding. Prompt recognition and management of bleeding complications are essential to ensure patient safety during enoxaparin therapy, especially following orthopedic surgery.
Correct Answer is {"dropdown-group-1":"A"}
Explanation
A. Whole: Complementary and alternative medicine (CAM) emphasizes treating the entire person, considering physical, mental, emotional, and spiritual aspects of health. It aims to restore balance and promote overall well-being.
B. Diseased: CAM focuses on addressing the root cause of illness, not just treating the symptoms of a disease. While disease management can be a part of CAM, it's not the sole focus.
C. Partial: CAM doesn't focus on treating only a part of the person. It aims for a comprehensive approach.
D. Impaired: While CAM can be used to address impairments, it has a broader scope that encompasses promoting overall health and preventing illness, not just treating existing limitations
