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 {"dropdown-group-1":"A","dropdown-group-2":"B"}
Explanation
• Sitting: The sitting position promotes optimal lung expansion and helps the client achieve maximum inhalation of the medication. Proper posture ensures that the airways are open and reduces the risk of aspiration or ineffective drug delivery. Sitting upright also enhances coordination between actuation and inhalation.
• Shake the inhaler: Shaking the metered dose inhaler mixes the medication and propellant evenly, ensuring a consistent and accurate dose is delivered. Failing to shake the inhaler can result in uneven dosing, reducing the effectiveness of therapy and potentially worsening the client’s respiratory symptoms.
Correct Answer is C
Explanation
A. Red blood cells: While red blood cell counts provide information about oxygen-carrying capacity and anemia, they do not directly reflect the anticoagulant effect of heparin or the risk of bleeding due to its use. Monitoring RBCs is not sufficient for safe heparin therapy.
B. International normalized ratio (INR): INR is primarily used to monitor warfarin therapy, not heparin. It measures the extrinsic pathway of coagulation, whereas heparin affects the intrinsic pathway, so INR is not the appropriate laboratory value for heparin monitoring.
C. Partial thromboplastin time (PTT): PTT measures the effectiveness of the intrinsic and common coagulation pathways, which are directly affected by heparin. Monitoring PTT helps ensure that the client maintains a therapeutic anticoagulation range and reduces the risk of bleeding or clot formation.
D. Hematocrit: Hematocrit reflects the proportion of red blood cells in the blood and can indicate blood loss over time. While important for general assessment, it does not specifically monitor heparin’s anticoagulant effect and is not the primary lab value to guide dosing.
