A client with a history of asthma reports having episodes of bronchoconstriction and increased mucous production while exercising. Which action should the nurse implement?

A. Evaluate upper and lower extremities for perfusion, pulse volume, and pitting edema:
This option focuses on assessing perfusion and circulation in the extremities. While it's important in certain situations, in the context of a client who recently underwent cardiac stent placement and is now experiencing chest pressure and shortness of breath, the priority is to assess the cardiac status more directly.

B. Listen for extra heart sounds, murmurs, and rhythm with the bell of the stethoscope:
This option involves auscultating the heart for abnormal sounds or rhythms. While it's a valuable assessment in general, in this particular scenario, obtaining an electrocardiogram (ECG) and initiating continuous cardiac monitoring would provide a more comprehensive and immediate evaluation of the cardiac status.

C. Obtain a 12-lead electrocardiogram and begin continuous cardiac monitoring:
This is the correct choice. Obtaining a 12-lead ECG and initiating continuous cardiac monitoring is crucial in assessing the client's cardiac function. It allows for the detection of any acute changes in the heart's electrical activity or rhythm, which is essential for timely intervention and management.

D. Verify troponin level assessments are scheduled every 3-6 hours for a series of three:
Monitoring troponin levels is important in assessing cardiac damage, but in this acute situation, obtaining an immediate ECG and initiating continuous cardiac monitoring take precedence for a more real-time evaluation of the client's cardiac status. Troponin levels may be monitored subsequently based on the initial findings.

A. Assess client for signs and symptoms of upper airway infection:
While upper airway infections can contribute to respiratory symptoms, the client's history of asthma and the exacerbation of symptoms during exercise suggest that asthma management should be a priority.

B. Determine if the client is using an inhaler before exercising:
This is a relevant consideration, and ensuring proper pre-exercise use of bronchodilators (such as an inhaler) is an important aspect of asthma management. However, the question is broader and involves a review of the client's overall asthma management.

C. Teach client to use pursed lip breathing when episodes occur:
Pursed lip breathing is a technique that can help manage symptoms, especially during episodes of bronchoconstriction. However, the focus here is on a more comprehensive assessment and review of the client's routine asthma management.

D. Review the client's routine asthma management prescriptions:
This is the correct answer. The client's reported symptoms during exercise suggest a potential need for adjustments to the routine asthma management plan. Reviewing the client's prescriptions, including the type and timing of medications, can help ensure optimal control of symptoms, especially during physical activity.
