For which client is guaifenesin indicated?
A client with chest congestion and thick mucus.
A client with experiencing anaphylaxis
A client with recurrent epistaxis.
A client with seasonal allergies.
The Correct Answer is A
A. A client with chest congestion and thick mucus: Guaifenesin is an expectorant that thins and loosens mucus in the airways, making it easier to cough up and clear secretions. It is indicated for clients with productive coughs and chest congestion.
B. A client experiencing anaphylaxis: Anaphylaxis is a severe, life-threatening allergic reaction that requires immediate treatment with epinephrine, antihistamines, and supportive care. Guaifenesin does not address the pathophysiology of anaphylaxis.
C. A client with recurrent epistaxis: Recurrent nosebleeds are not treated with guaifenesin. Management involves identifying the underlying cause, nasal care, or topical interventions rather than an expectorant.
D. A client with seasonal allergies: Seasonal allergies primarily cause sneezing, itching, and watery eyes. Antihistamines or intranasal corticosteroids are indicated, whereas guaifenesin does not relieve allergy symptoms.

Correct Answer is D
Explanation
A. Fexofenadine: Fexofenadine is a second-generation antihistamine typically administered orally. It is non-sedating and not available in an intravenous form, so it is not suitable for immediate treatment of pruritus during an acute blood transfusion reaction.
B. Loratadine: Loratadine is also a second-generation oral antihistamine. It does not have an intravenous formulation and its onset is slower, making it ineffective for rapid symptom relief in acute transfusion reactions.
C. Cetirizine: Cetirizine is a second-generation antihistamine available orally. Although it is effective for allergic reactions, it does not have an IV form for rapid intervention during a transfusion-related pruritus episode.
D. Diphenhydramine: Diphenhydramine is a first-generation antihistamine that can be administered intravenously for rapid relief of pruritus during acute allergic reactions, including blood transfusion reactions. Its IV form allows immediate onset of action, which is critical in managing these acute symptoms.
Correct Answer is A
Explanation
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.
