A nurse is reinforcing teaching with a client who is to start taking montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?

A. Instruct the client to use a pursed-lip breathing technique.

Pursed-lip breathing is a technique commonly used to help relieve dyspnea, particularly in individuals with COPD. This technique involves breathing in through the nose and exhaling slowly through pursed lips, which helps to prolong exhalation, reduce airway collapse, and improve oxygen exchange. While pursed-lip breathing can be beneficial, it should not be the priority action when the client reports difficulty breathing. Before initiating any breathing techniques, the nurse should first assess the client's respiratory status to determine the severity of the breathing difficulty and whether additional interventions are necessary.

B. Evaluate the client's respiratory status.

This is the correct priority action in this scenario. When a client with COPD reports difficulty breathing, the nurse's first step should be to thoroughly assess the client's respiratory status. This assessment involves evaluating respiratory rate, depth, effort, oxygen saturation levels, auscultating lung sounds, and assessing for signs of respiratory distress. By conducting a comprehensive assessment, the nurse can determine the severity of the client's symptoms, identify any potential exacerbating factors or complications, and make informed decisions regarding appropriate interventions.

C. Increase the oxygen flow to 3 L/min.

While increasing the oxygen flow may be a consideration if the client's oxygen saturation is low, it should not be the immediate priority without first assessing the client's respiratory status. Increasing oxygen flow without proper assessment could potentially worsen hypercapnia in some COPD patients and may not address the underlying cause of the client's difficulty breathing. Therefore, this action should be based on assessment findings rather than being the initial response.

D. Have the client cough and expectorate secretions.

Coughing and expectorating secretions can be helpful in clearing the airways and improving breathing in individuals with COPD, especially if secretions are contributing to the difficulty breathing. However, similar to the pursed-lip breathing technique, this action should not be the priority without first assessing the client's respiratory status. The nurse should determine whether secretions are indeed present and causing the difficulty breathing before instructing the client to cough and expectorate. Therefore, this option should follow a thorough respiratory assessment.

A. Air moves in and out of a wound in the chest wall.

In an open pneumothorax, also known as a sucking chest wound, there is a communication between the pleural space and the external environment through a wound in the chest wall. This allows air to move freely in and out of the pleural cavity during respiration. As a result, there is a loss of negative pressure within the pleural space, impairing lung expansion and leading to respiratory compromise. This condition is considered a medical emergency and requires prompt intervention to prevent tension pneumothorax and respiratory failure.

B. Air cannot pass freely into the thoracic cavity through a chest wound.

In an open pneumothorax, air can pass freely into the thoracic cavity through the chest wound. This communication between the external environment and the pleural space results in air movement in and out of the wound during respiration.

C. There are no audible sounds in an open pneumothorax.

In an open pneumothorax, there may be audible sounds, such as sucking or hissing sounds, particularly during inspiration. These sounds occur due to the movement of air in and out of the chest wound and can be indicative of the condition.

D. The air is trapped when it enters the cavity.

In an open pneumothorax, the air is not trapped when it enters the pleural cavity. Instead, air moves freely in and out of the wound in the chest wall, leading to respiratory compromise and potential progression to tension pneumothorax if left untreated.
