A patient has been prescribed rivaroxaban (Xarelto) for deep vein thrombosis (DVT). Which statement by the patient indicates understanding of medication teaching?
“I will take aspirin if I get a headache.”
“I will avoid activities that may cause injury.”
“I will take my medication with food.”
“I will stop taking my medication if I feel better.”.
The Correct Answer is B
This statement indicates that the patient understands that rivaroxaban (Xarelto) is an anticoagulant that can increase the risk of bleeding and bruising. The patient should avoid activities that may cause injury, such as contact sports, sharp objects, or falls.
Choice A is wrong because aspirin is also an antiplatelet drug that can further increase the risk of bleeding when taken with rivaroxaban. The patient should not take aspirin or any other nonsteroidal anti-inflammatory drugs (NSAIDs) without consulting the prescriber.
Choice C is wrong because rivaroxaban can be taken with or without food. The patient does not need to take the medication with food to prevent stomach upset or absorption problems.
Choice D is wrong because rivaroxaban should be taken as prescribed and not stopped abruptly without consulting the prescriber. Stopping the medication can increase the risk of blood clots and stroke. The patient should not stop taking the medication even if they feel better or have no symptoms.

Correct Answer is ["A","D"]
Explanation
A patient with a high aPTT result is at risk for bleeding, so assessing for signs and symptoms of bleeding is important.
Holding heparin therapy per protocol is also appropriate, as heparin is the cause of the prolonged aPTT.
The other choices are wrong because:
• Choice B is wrong because continuing heparin therapy at the current rate will increase the risk of bleeding and further prolong the aPTT.
• Choice C is wrong because decreasing heparin therapy per protocol is not enough to reverse the effects of heparin.
Heparin should be stopped until the aPTT returns to the therapeutic range.
• Choice E is wrong because increasing heparin therapy per protocol will worsen the situation and cause more bleeding and coagulation problems.
The normal range for aPTT is 25 to 35 seconds, and the therapeutic range for heparin therapy is 60 to 80 seconds.A result of 90 seconds indicates excessive anticoagulation and increased bleeding risk.
Correct Answer is C
Explanation
Activated partial thromboplastin time (aPTT).
Dabigatran (Pradaxa) is a direct oral anticoagulant (DOAC) that inhibits thrombin, a key enzyme in the coagulation cascade.
Dabigatran prolongs the aPTT, which is a measure of the intrinsic and common pathways of coagulation.The aPTT can be used to monitor the anticoagulant effect of dabigatran, although routine monitoring is not required.
Choice A) Prothrombin time (PT) is wrong because PT measures the extrinsic and common pathways of coagulation, which are not affected by dabigatran.
PT is used to monitor warfarin therapy, not dabigatran.
Choice B) International normalized ratio (INR) is wrong because INR is a standardized version of PT that is used to monitor warfarin therapy, not dabigatran.
INR is not affected by dabigatran.
Choice D) Platelet count is wrong because platelet count is a measure of the number of platelets in the blood, which are involved in primary hemostasis.
Platelet count is not affected by dabigatran, which acts on secondary hemostasis.
Normal ranges for these tests are:
• aPTT: 25 to 35 seconds
• PT: 11 to 13.5 seconds
• INR: 0.8 to 1.2
• Platelet count: 150,000 to 450,000 per microliter of blood
