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.

A. Blood pressure: The client's BP rose from 164/80 to 176/82. While we want this to stabilize, a "finding" of improvement would be a specific trend downward; however, BP can be volatile during the acute phase of an MI due to pain and compensation. B. Urinary output: While important for assessing organ perfusion, the current exhibits do not provide a baseline for urine output, making it a less immediate indicator of "improvement" than pain or vitals in the hyper-acute phase. C. Respiratory rate: The client was tachypneic (22–24/min). A decrease toward the normal range (12–20/min) indicates decreased physiological stress and better oxygenation. D. Oxygenation saturation: The client’s SpO2 dropped to 89%. An increase to >94 (especially with the prescribed 2 L/min of O2) indicates improved gas exchange and lung perfusion. E. Heart rate: The client was tachycardic (110–120/min) and irregular. A decrease in rate and a return to a regular sinus rhythm (often aided by the prescribed Metoprolol) indicates decreased myocardial oxygen demand. F. Echocardiogram results: An echo shows the structural damage or "wall motion abnormalities" caused by the MI. While it helps with diagnosis and long-term prognosis, it won't show immediate "improvement" in the same way bedside vitals and pain assessments do during the acute intervention. G. Pain level: The client reported pain at a 7/10. A decrease in this number (monitored after Nitroglycerin and Morphine administration) is a primary indicator that myocardial ischemia is resolving.
