A nurse is caring for a client in an emergency department (ED).Exhibits Which of the following findings in the client's medical record requires follow-up by the nurse? Select all that apply

Rationale: A. Blood pressure: Orthostatic hypotension is evident from the drop in systolic and diastolic pressure when standing, indicating fluid and electrolyte imbalance. This may reflect volume depletion due to purging and requires monitoring to prevent fainting or falls. B. Syncope: The client reports repeated fainting episodes, a red flag when paired with orthostatic hypotension and electrolyte disturbances. This suggests unstable cardiovascular status and raises the risk of injury or sudden cardiac events. C. ECG: Sinus tachycardia with premature ventricular contractions indicates cardiac irritability likely due to electrolyte imbalance, especially hypokalemia. Continuous cardiac monitoring and correction of abnormalities are needed. D. Albumin: An albumin level of 2.6 g/dL indicates significant malnutrition and protein deficiency, compromising immune function and wound healing. This also suggests a chronic issue requiring dietetic intervention and nutritional rehabilitation. E. Potassium: Potassium at 3.0 mEq/L is dangerously low and a known contributor to cardiac arrhythmias and muscle weakness. Replenishment and close monitoring are critical to avoid complications such as cardiac arrest. F. Sodium: Although sodium is only slightly low at 134 mEq/L, in the context of purging and poor intake, this could indicate dilutional hyponatremia. It increases seizure risk and needs assessment of fluid status and intake behaviors.
