PaCO₂ 55 mm Hg
🧿 A PaCO₂ of 55 mm Hg is elevated above the expected range of 35–45 mm Hg.
🧿 Elevated PaCO₂ indicates carbon dioxide retention, which reflects inadequate alveolar ventilation.
🧿 Effective respiratory treatment should improve ventilation and promote removal of carbon dioxide from the lungs.
🧿 Persistent hypercapnia suggests that ventilation remains impaired despite treatment.
🧿 Pneumonia can interfere with ventilation through alveolar inflammation, secretions, and consolidation.
🧿 Continued carbon dioxide retention may eventually contribute to respiratory acidosis if the condition worsens.
🧿 The nurse should continue monitoring respiratory effort, mental status, oxygenation, and arterial blood gases.
🧿 A PaCO₂ of 55 mm Hg therefore indicates that the respiratory treatment has been ineffective.
Rhonchi in the right lung
🧿 Rhonchi are low-pitched adventitious breath sounds commonly associated with secretions in the larger airways.
🧿 Persistent rhonchi indicate that airway secretions have not been completely cleared.
🧿 Effective pneumonia treatment should reduce airway inflammation and improve secretion clearance.
🧿 Retained secretions can obstruct airflow and interfere with adequate ventilation.
🧿 Coughing, deep breathing, hydration, and mobility can help mobilize respiratory secretions.
🧿 Persistent rhonchi may indicate continuing mucus accumulation despite therapy.
🧿 The nurse should reassess the client's ability to cough and clear secretions effectively.
🧿 Rhonchi remaining in the right lung therefore indicate ineffective treatment.
Oxygen saturation greater than 94%
🧿 An oxygen saturation above 94% indicates improved oxygenation compared with the client's previous saturation of 89% on room air.
🧿 Improved oxygen saturation suggests that more oxygen is successfully reaching the bloodstream.
🧿 Antibiotic treatment can reduce pulmonary infection and inflammation, improving alveolar gas exchange.
🧿 Respiratory interventions can also improve ventilation and help open previously poorly ventilated alveoli.
🧿 Adequate oxygen saturation indicates that hemoglobin is carrying an appropriate amount of oxygen to body tissues.
🧿 Improvement from hypoxemia toward an acceptable saturation is an important sign of clinical recovery.
🧿 The nurse should continue monitoring saturation trends during rest and activity.
🧿 An oxygen saturation greater than 94% therefore indicates effective treatment.
Diminished breath sounds in the right lung
🧿 Diminished breath sounds suggest reduced movement of air through the affected portion of the lung.
🧿 Pneumonia-related consolidation can reduce airflow into involved alveoli.
🧿 Effective treatment should improve ventilation as inflammation, secretions, and consolidation resolve.
🧿 Persistent decreased breath sounds may indicate continued alveolar filling or poor lung expansion.
🧿 Reduced airflow can contribute to ongoing impairment of oxygen and carbon dioxide exchange.
🧿 The nurse should compare breath sounds bilaterally and monitor for worsening respiratory findings.
🧿 Persistent diminished sounds in the previously affected right lung suggest incomplete resolution of pneumonia.
🧿 Diminished right-sided breath sounds therefore indicate ineffective treatment.
Symmetrical chest expansion
🧿 Symmetrical chest expansion indicates that both sides of the thorax are moving evenly during inspiration.
🧿 Equal expansion suggests improved ventilation and lung movement on both sides.
🧿 Pneumonia can cause decreased expansion on the affected side when pain, consolidation, or reduced ventilation is significant.
🧿 Improved respiratory function should allow more equal movement of the chest wall.
🧿 Symmetry also suggests that no major unilateral restriction is interfering with lung expansion.
🧿 Adequate chest expansion supports more effective delivery of air into the lungs.
🧿 The finding is consistent with improvement in the client's respiratory status after treatment.
🧿 Symmetrical chest expansion therefore indicates effective treatment.
Client ambulates without shortness of breath
🧿 Ambulating without shortness of breath demonstrates improved activity tolerance and respiratory reserve.
🧿 The client initially had dyspnea-related findings, including tachypnea and low oxygen saturation.
🧿 Effective pneumonia treatment should improve gas exchange enough for the client to tolerate increasing activity.
🧿 Absence of exertional dyspnea suggests that oxygen delivery is meeting the body's increased demands during ambulation.
🧿 Improved activity tolerance also indicates that the work of breathing has decreased.
🧿 Functional improvement is an important measure of recovery in addition to laboratory and physical assessment findings.
🧿 The nurse should continue to monitor oxygen saturation and symptoms during progressive activity.
🧿 Walking without shortness of breath therefore indicates effective treatment.
