The healthcare provider prescribes the anticoagulant heparin for a client with a pulmonary embolism. Before initiating the medication, the nurse should ensure that which drug is readily available in case of heparin overdose?

A) Determine if the client is taking the medication before meals: While the timing of medication relative to meals can affect absorption, this action assumes a specific problem without first clarifying the client's concerns. It's important to understand the nature of the client's issue before assessing medication administration.
B) Ask if his morning voiding is dark colored: Dark-colored urine may be a side effect of some medications, but this is a less direct approach to understanding why the client feels the medication is not working. It does not directly address the effectiveness of the medication.
C) Explore what the client means by the drug not working: This is the most appropriate initial intervention. Understanding the client's perception and specific concerns about the medication's effectiveness will guide further actions, such as assessing medication adherence, side effects, or the need for a medication adjustment.

D) Evaluate the client for signs of dyskinesia: While assessing for dyskinesia is important, it is more of a specific follow-up step. The priority is to understand the client's concerns about the medication's overall effectiveness before focusing on specific side effects.

A. Gout: Aspirin is not typically used for treating gout. Gout is commonly treated with medications like allopurinol or colchicine, and nonsteroidal anti-inflammatory drugs (NSAIDs) are used selectively.
B. Sepsis: Aspirin is not a primary treatment for sepsis. Sepsis is usually treated with antibiotics, fluid resuscitation, and supportive care.
C. Myocardial infarction: Aspirin is beneficial for preventing further myocardial infarctions (heart attacks) in patients with a history of cardiovascular events or at high risk. It works by inhibiting platelet aggregation, thereby reducing the risk of blood clot formation that can lead to heart attacks.
D. Rheumatoid arthritis: Although aspirin can be used for symptomatic relief in rheumatoid arthritis due to its anti-inflammatory properties, it is not the primary treatment. Other medications, such as disease-modifying antirheumatic drugs (DMARDs) and nonsteroidal anti-inflammatory drugs (NSAIDs), are typically used.
