A nurse is caring for an adult client who has borderline personality disorder (BPD). The nurse completed a review of the client's electronic health record. Which of the following client findings require immediate follow-up by the nurse? (Select all that apply.)

Choice A rationale: Positive hepatitis viral study indicates active infection, requiring immediate follow-up due to risk of liver damage, transmission, and complications with alcohol and intravenous drug use. Choice B rationale: BUN level of 11 mg/dL is within normal range, reflecting adequate renal function and not requiring immediate follow-up or intervention. Choice C rationale: Frequent hospitalizations reflect chronic instability but do not represent an acute, immediate threat requiring urgent follow-up at this time. Choice D rationale: Financial stress impacts long-term care planning but is not an immediate clinical safety concern requiring urgent follow-up. Choice E rationale: Increased alcohol and intravenous drug use poses immediate risk for overdose, withdrawal, infection, and impaired judgment, requiring urgent follow-up and intervention. Choice F rationale: Risky sexual behaviors increase long-term infection risk but are not an immediate clinical emergency requiring urgent follow-up during this encounter. Choice G rationale: Sodium level of 131 mEq/L indicates hyponatremia, which can cause neurological symptoms and requires immediate follow-up to prevent complications. Choice H rationale: Loss of parent contributes to grief and emotional distress but does not represent an immediate physiological threat requiring urgent follow-up. Choice I rationale: Hemoglobin of 14 g/dL is within normal range, showing adequate oxygen-carrying capacity and not requiring immediate follow-up.
