Patient Data Exhibits here The nurse is reviewing the physician's orders. Which of the following physician's orders requires priority attention from the nurse? Select all that apply.

Choice A rationale: This order is useful to evaluate the client's electrolyte levels, renal function, and acid-base balance, as she has ERSD and missed her dialysis session. She may have hyperkalemia, metabolic acidosis, or uremia, which can affect her cardiac and neurological status. Choice B rationale: This order is helpful to assess the client's cardiac structure and function, as she has a history of CAD and HTN and may have developed heart failure or valvular disease. Choice C rationale: This order is beneficial to rule out any intra-abdominal causes of the client's nausea and poor appetite, such as infection, obstruction, or bleeding. Choice D rationale: This order is necessary to identify any possible source of infection or sepsis, as the client has been ill for 3 days and has a history of diabetes, which can impair her immune system. Choice E rationale: This order is important to assess the client's cardiac and pulmonary status, as she has a history of CAD and is presenting with chest discomfort and lightheadedness, which could indicate a cardiac event or pulmonary edema. Choice F rationale: This order is essential to monitor the client's heart rate and rhythm, as she has a history of CAD and HTN and is at risk for arrhythmias, ischemia, and infarction. Choice G rationale: This order is important to evaluate the client's hematological status, as she has ERSD and may have anemia, leukocytosis, or thrombocytopenia. Choice H rationale: This order is crucial to obtain a baseline of the client's cardiac electrical activity and to detect any signs of acute coronary syndrome, such as ST-segment elevation or depression, T wave inversion, or Q waves.
