A nurse is planning care for a client with acute kidney injury. The nurse should recognize that which assessment data best supports the nursing diagnosis of Excess Fluid Volume?

The nurse should first place the client in high Fowler's position to ease the breathing and improve oxygenation, as the client is experiencing increased dyspnea and chest pain. This position allows for better lung expansion and can be a critical immediate intervention. Following this, the nurse should obtain IV access to facilitate the administration of medications and fluids as needed. IV access is essential for the rapid administration of potential treatments, including anticoagulants, which may be required if a pulmonary embolism is confirmed. These actions are prioritized to address the client's immediate respiratory distress and to prepare for further interventions based on the evolving clinical situation. It is important to note that each clinical scenario is unique, and the interventions should be tailored to the client's specific needs and the healthcare provider's clinical judgment.

A. Tachypnea: Tachypnea, or rapid breathing, is a common symptom of pulmonary embolism. It occurs as the body attempts to compensate for decreased oxygenation and increased carbon dioxide levels resulting from impaired blood flow to the lungs. Tachypnea helps to improve gas exchange by increasing ventilation.

B. Wet cough: A wet or productive cough may occur in conditions such as pneumonia or chronic bronchitis but is not typically associated with pulmonary embolism. Pulmonary embolism is more commonly characterized by symptoms such as dyspnea, chest pain, and tachypnea.

C. Dull chest pain: Chest pain associated with pulmonary embolism is often sharp and pleuritic, meaning it worsens with deep breathing or coughing. It may be described as stabbing or like a "knife-like" sensation. Dull chest pain is not a typical finding in pulmonary embolism.

D. Episodes of apnea: While severe cases of pulmonary embolism can lead to respiratory failure and apnea, it is not a common presenting symptom. Most clients with pulmonary embolism will exhibit tachypnea as a compensatory mechanism to maintain adequate oxygenation.
