Which intervention should the nurse prioritize for a patient exhibiting a respiratory rate of 32 breaths per minute with shallow effort?

A. Administer oxygen as prescribed: A respiratory rate of 32 breaths per minute indicates significant tachypnea and potential respiratory distress. Supplemental oxygen helps satisfy the increased metabolic demand for O2 and reduces the work of breathing. This physiological intervention addresses the most urgent need at the base of Maslow's hierarchy. B. Reposition the patient for comfort: While a High-Fowler's position can assist with lung expansion, simply repositioning for "comfort" is insufficient for a patient with such a high respiratory rate. It does not provide the necessary oxygenation needed to treat underlying hypoxia. It is a supportive measure rather than a primary treatment. C. Discuss underlying stressors with the patient: Tachypnea can be caused by anxiety, but the nurse must first rule out and treat physical respiratory failure. Addressing psychosocial stressors before ensuring adequate gas exchange is a violation of clinical priority setting. Physical stability must be achieved before exploring emotional or psychological causes. D. Provide emotional support: Empathy and support are core components of nursing care but do not correct an abnormal respiratory rate or shallow effort. If the cause is physiological, such as a pulmonary embolism or pneumonia, emotional support will not prevent respiratory arrest. Physiological needs must be met first to ensure patient survival.
