The nurse is reviewing the client's medical record. Which of the following findings indicates the client's condition has improved? Select all that apply.

Rationale: A. Urinary output: The client’s intake was 500 mL and output only 32 mL, indicating oliguria. This low output does not reflect improvement in renal perfusion or fluid balance and may suggest hypoperfusion or early organ compromise related to myocardial infarction or hypotension. B. Blood pressure: The client’s blood pressure decreased from a hypertensive reading of 176/82 mm Hg to 110/62 mm Hg. While this may reflect some response to interventions, the value is borderline hypotensive and requires continued monitoring. It does not clearly indicate overall improvement in hemodynamic stability at this stage. C. Echocardiogram results: The echocardiogram confirmed myocardial infarction, which is a pathological finding rather than an improvement. The result provides diagnostic information but does not reflect a positive change in clinical condition. D. Heart rate: The client’s heart rate decreased from 120/min to 100/min after interventions, indicating reduced sympathetic stimulation and improved hemodynamic response. Lower heart rate helps decrease myocardial oxygen demand and is a positive sign of stabilization. E. Pain level: Chest pain decreased from 7/10 to 5/10 after two doses of nitroglycerin, showing effective analgesic response and reduction in myocardial ischemia-related discomfort. Pain relief contributes to decreased sympathetic activation and improved clinical status. F. Respiratory rate: Respiratory rate decreased from 24/min to 22/min, and the client reports easier breathing with supplemental oxygen. This reflects improved oxygenation and reduced respiratory distress, indicating stabilization of pulmonary status. G. Oxygenation saturation: Oxygen saturation improved from 89% on room air to 92% on 2 L/min via nasal cannula. This indicates better oxygen delivery and tissue perfusion, reflecting a positive response to oxygen therapy.
