Correct Answer is D
Explanation
Choice A rationale
Maintaining narcan (naloxone) on standby is not directly related to anticoagulant therapy. Narcan is used to reverse opioid overdoses, not to manage the effects of anticoagulants.
Choice B rationale
Notifying the healthcare provider of any patient receiving this drug is a general action but not an appropriate nursing diagnosis. Nursing diagnoses focus on identifying specific patient needs and planning care to address those needs.
Choice C rationale
Evaluating the patient for PT (prothrombin time) for 2.5 is an action, not a nursing diagnosis. Nursing diagnoses identify patient needs and risks, guiding the planning and implementation of care.
Choice D rationale
Establishing safety precautions is an appropriate nursing diagnosis for a patient on anticoagulant therapy. Anticoagulants increase the risk of bleeding, so ensuring patient safety and preventing injury is crucial to minimize this risk. .
Correct Answer is B
Explanation
Choice A rationale
Antiplatelets do not stimulate the plasmin system, which is involved in breaking down clots.
Choice B rationale
Antiplatelet medications work by altering the formation of the platelet plug, preventing platelets from clumping together.
Choice C rationale
They do not initiate the clotting cascade, which is a separate process from platelet aggregation.
Choice D rationale
They do not interfere with the clotting cascade directly but affect platelet aggregation. .
