For which client is antiplatelet therapy indicated?

A client needing stroke prevention

A client with a vitamin K deficiency

A client with a low platelet count

A client diagnosed with leukemia

Answer and Explanation

The Correct Answer is A

A. A client needing stroke prevention: Antiplatelet therapy is indicated for clients at risk of ischemic stroke or recurrent stroke because it helps prevent platelet aggregation, reducing the likelihood of clot formation in the arteries. This intervention is especially beneficial in clients with a history of transient ischemic attacks or atherosclerotic cardiovascular disease.

B. A client with a vitamin K deficiency: Vitamin K deficiency primarily affects clotting factor synthesis, leading to a bleeding tendency. Antiplatelet therapy would increase the risk of bleeding in these clients, making it contraindicated rather than indicated.

C. A client with a low platelet count: Clients with thrombocytopenia are already at risk for bleeding, and antiplatelet therapy would further impair clot formation, increasing the potential for hemorrhage. It is therefore avoided in these situations.

D. A client diagnosed with leukemia: Leukemia can be associated with low platelet counts or abnormal platelet function, placing the client at risk for bleeding. Administering antiplatelet therapy could exacerbate hemorrhagic complications rather than provide benefit.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}

Explanation

• Sit down after taking nitroglycerin: Nitroglycerin causes rapid vasodilation, which can lead to a sudden drop in blood pressure shortly after administration. Sitting or lying down helps reduce the risk of dizziness, syncope, and falls during this period. This instruction is especially important because sublingual nitroglycerin acts quickly.

• Hypotension: Nitroglycerin relaxes vascular smooth muscle, leading to decreased preload and afterload. This vasodilatory effect can cause orthostatic or systemic hypotension, particularly with the first dose. Monitoring and education focus on preventing complications related to low blood pressure, such as lightheadedness or fainting.

A. Check the client's activated partial thromboplastin time (aPTT). B. Hold both medications and clarify the order with the prescriber. C. Administer the injections in separate sites. D. Administer the enoxaparin and hold the heparin.

Correct Answer is B

Explanation

A. Check the client's activated partial thromboplastin time (aPTT): While aPTT is used to monitor unfractionated heparin therapy, it does not address the potential issue of duplicate anticoagulation therapy. Relying solely on lab values could put the client at risk for serious bleeding.

B. Hold both medications and clarify the order with the prescriber: Administering both heparin and enoxaparin without clarification can result in excessive anticoagulation and significant bleeding risk. Holding the medications and contacting the prescriber ensures safe medication administration and prevents potential adverse effects.

C. Administer the injections in separate sites: Even if given in separate sites, administering both heparin and enoxaparin simultaneously could lead to additive anticoagulant effects and increase the risk of hemorrhage. Site separation does not mitigate systemic risks.

D. Administer the enoxaparin and hold the heparin: Giving enoxaparin without clarifying the order for heparin could result in duplicate anticoagulation, increasing the potential for bleeding complications. Safe practice requires prescriber clarification before administration.
