A client with peripheral artery disease receives a meal tray from the dietary department. Which statement indicates to the nurse that the client is following a meal plan to support healthy blood flow?

Brief introduction:

Asthma management focuses on reducing airway inflammation and preventing future acute exacerbations. Once the client is stabilized with a patent airway and improved oxygenation, the nurse must address environmental triggers and physiological recovery. Effective nursing care transitions from emergency intervention to maintenance, ensuring the patient maintains adequate ventilation-perfusion balance while gradually returning to baseline respiratory function without excessive supplemental support.

Rationale:

A. Identifying and avoiding asthma triggers is essential for long-term management and preventing readmission. Common triggers include exercise, cold air, or recent viral infections, as seen in this client's history. Discussing these factors helps the client develop a self-management plan to recognize early signs of worsening airway constriction.

B. Discussing aggressive treatments is unnecessary because the client is currently showing improvement with standard therapy. Her breath sounds are now clear, and her oxygen saturation has reached 98% with minimal support. Initiating conversations about invasive interventions like intubation is clinically inappropriate for a patient who is successfully stabilizing.

C. Allowing a position of comfort, such as the high-Fowler position, optimizes lung expansion and reduces the work of breathing. Proper positioning prevents diaphragmatic compression, which is vital for a client recovering from subcostal retractions and respiratory distress. This non-invasive support facilitates continued airway patency and patient comfort throughout the shift.

D. Positive pressure ventilation is indicated for respiratory failure or severe distress unresponsive to initial pharmacological therapy. Since the client's oxygen saturation is now 98% and wheezing has resolved, she no longer meets the clinical criteria for such an aggressive respiratory support measure. Her current status indicates successful response to nebulized albuterol.

E. Obtaining a sputum culture is not indicated as there is no evidence of purulent secretions or pneumonia. While she had a cold, asthma is a chronic inflammatory condition, not a primary bacterial infection requiring immediate culture and sensitivity testing. Priority is placed on airflow dynamics rather than microbiological testing in this scenario.

F. Continuous or frequent monitoring of oxygen saturation is vital to ensure the client does not desaturate as the albuterol effect wears off. Because asthma can involve recurrent bronchospasm, the nurse must ensure the client maintains a saturation >94%. This objective data guides the titration of supplemental oxygen throughout the recovery period.

G. Weaning supplemental oxygen is appropriate when the saturation is stable at 98% on nasal cannula. The goal is to return the client to room air while maintaining adequate tissue oxygenation levels. Gradually reducing the flow rate allows the nurse to assess if the client’s own respiratory effort is sufficient.

H. Deep tracheal suctioning is an invasive procedure for patients unable to clear secretions, usually those who are intubated. This client is conscious, talking, and has clear lung fields, making such a painful and risky procedure entirely unnecessary. Tracheal suctioning can actually trigger further bronchospasm in a sensitive asthma patient.

Warfarin is an oral anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors (II, VII, IX, and X). Because vitamin K is a direct physiological antagonist to warfarin, fluctuations in dietary intake can lead to unpredictable changes in the International Normalized Ratio (INR). Maintaining a stable balance between the drug and the vitamin is essential to prevent life-threatening hemorrhage or recurring thromboembolic events.

Rationale:

A. Consistency is the most vital dietary principle for patients on warfarin therapy. Consuming the same amount of vitamin K daily allows for a stable and predictable INR value, ensuring the medication dose remains therapeutic. Significant changes in leafy green consumption can either cause clotting or bleeding.

B. Increasing the intake of dark green leafy vegetables will counteract the effects of warfarin and lower the INR. This puts the client at an increased risk for thrombus formation and stroke. The goal is not to maximize vitamin K but to achieve hemodynamic stability through dietary uniformity.

C. Completely avoiding vitamin K is neither practical nor healthy, as it is a necessary nutrient found in many beneficial foods. The mechanism of warfarin relies on a stable baseline of vitamin K rather than the total absence of it. Eliminating it entirely can cause the INR to rise to dangerous levels.

D. Prescribing a specific, rigid amount of vegetables for a limited timeframe ignores the need for lifelong dietary stability during therapy. Warfarin management requires a long-term commitment to consistency that extends as long as the medication is prescribed. Fixed-term instructions do not account for the variable metabolism of the drug.
