A patient has a diagnosis of Impaired Gas Exchange. Which assessment finding shows that the interventions have been effective?

A. Oral mucosa:

The oral mucosa, including the inside of the mouth, tongue, and lips, is a reliable indicator of cyanosis. Cyanosis appears as a bluish discoloration of these tissues due to decreased oxygen saturation in the arterial blood. Assessing the oral mucosa is an essential component of clinical examination, especially in patients with respiratory conditions like asthma, as it provides valuable information about oxygenation status.

B. Tip of the nose:

While the tip of the nose may exhibit cyanosis in some cases, it is not considered as reliable of an indicator as the oral mucosa. The nasal tip is more susceptible to external factors such as cold temperatures or poor circulation, which can cause temporary discoloration. Therefore, it may not always accurately reflect the oxygenation status of the patient compared to the oral mucosa.

C. Ear lobes:

Cyanosis may be observed in the ear lobes in cases of severe hypoxemia, but it is not as reliable of an indicator as the oral mucosa. The ear lobes are less commonly assessed for cyanosis compared to other areas such as the lips, nail beds, or oral mucosa. While cyanosis may be present in the ear lobes, it is not typically the primary site assessed for oxygenation status.

D. Eyelids:

Cyanosis is not typically observed in the eyelids and is not considered a reliable indicator of hypoxemia. The eyelids are not commonly assessed for cyanosis during clinical examinations. While the conjunctiva (the lining inside the eyelids) may appear pale in cases of severe anemia, it is not a specific sign of hypoxemia. Assessment of the oral mucosa, lips, and nail beds is preferred for evaluating oxygenation status in patients with respiratory conditions like asthma.

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.
