How should a nurse integrate evidence-based practice (EBP) when using SBAR to communicate a potential medication error?

A. Decreased chest expansion during inhalation:This finding is more indicative of musculoskeletal stiffness, pain, or restrictive lung disease rather than a failure of the mucociliary escalator. While it affects ventilation, it does not directly reflect the status of the cilia or mucus transport. It is a measure of thoracic compliance.

B. Inspiratory wheezing:Wheezing indicates airway narrowing, which can be caused by various factors including bronchospasm or inflammation. While mucus can narrow the airway, wheezing is not the most specific indicator of impaired ciliary function. It is a sign of obstruction rather than a specific failure of clearance.

C. Clubbing of fingers:Clubbing is a sign of chronic systemic hypoxemia and is common in long-standing conditions like bronchiectasis or lung cancer. It reflects the duration of the disease rather than the acute functional status of the mucociliary system. It is a late-stage physical finding of chronic respiratory distress.

D. Chronic cough with sputum production:The mucociliary escalator is responsible for moving trapped particles and mucus up and out of the lungs. When this system fails, secretions accumulate in the airways, necessitating a cough to clear the debris. A productive cough is the clinical consequence of ineffective ciliary transport.

A. Understanding the patient's self-reported pain: Pain is a subjective, multidimensional experience, and the patient's own description is the most reliable indicator of its presence and intensity. A comprehensive assessment of location, character, and severity must occur before any clinical decisions can be made. This self-report serves as the baseline for all subsequent therapeutic interventions.

B. Beginning immediate pharmacological intervention: Administering medication before a thorough assessment is completed can mask clinical symptoms and lead to inappropriate treatment. The nurse must first identify the type and severity of pain to select the correct analgesic according to the WHO pain ladder. Assessment is always the priority step in the nursing process.

C. Assessing the psychological background: While psychological factors influence the perception of pain, they are secondary to the primary physical assessment of the painful stimulus. Focusing on the background before the actual pain characteristics can lead to clinical bias and undertreatment. The immediate priority is the patient's current, acute sensory experience.

D. Implementing selected nonpharmacological treatments: Nonpharmacological interventions like repositioning or distraction are useful adjuncts but should not be implemented without a preliminary assessment. The nurse must determine if the pain is acute or chronic to choose the most effective modality. Assessment must guide the selection of any nonpharmacological intervention.
