Hemodialysis

A nurse is monitoring a patient undergoing hemodialysis for the first time. Which assessment finding requires the most immediate intervention?

1 Blood pressure of 90/60 mmHg with mild dizziness
2 Access site with slight redness and warmth
3 Sudden onset of chest pain with shortness of breath ✓ 정답
4 Muscle cramping in the lower extremities

해설

Sudden chest pain with shortness of breath during hemodialysis suggests air embolism, a life-threatening emergency requiring immediate action (e.g., stopping dialysis, positioning, oxygen). Other findings like hypotension, access site redness, or cramping are concerning but less urgent.

Clinical Reasoning and Prioritization

This question tests the ability to prioritize care for a patient undergoing an initial hemodialysis treatment. The core concept is recognizing life-threatening complications over expected side effects or potential infections. The correct answer is the sudden onset of chest pain with shortness of breath.

Analysis of the Correct Answer
Sudden onset of chest pain with shortness of breath during hemodialysis is a medical emergency. This presentation is highly suspicious for an air embolism or a pneumothorax/hemothorax. These are rare but catastrophic complications directly linked to vascular access, particularly with central venous catheters. The provided evidence highlights that insertion and use of a Permcath (a type of tunneled hemodialysis catheter) can lead to pneumothorax, hemothorax, and cardiac arrhythmias ^[4]. An air embolism occurs when air enters the venous system through an open catheter lumen or a disconnected line, traveling to the right ventricle and obstructing pulmonary blood flow. A pneumothorax can occur if the lung apex is punctured during catheter insertion in the internal jugular or subclavian vein. Both conditions cause a sudden drop in oxygenation, leading to chest pain, severe dyspnea, hypotension, and potentially cardiac arrest. This finding indicates an immediate threat to airway, breathing, and circulation, requiring the most rapid intervention, such as clamping the catheter, placing the patient in the left lateral Trendelenburg position (for suspected air embolism), administering high-flow oxygen, and notifying the provider.

Analysis of Incorrect Answers

1. Blood pressure of 90/60 mmHg with mild dizziness
Hypotension is a common finding during hemodialysis, often caused by rapid fluid removal (intradialytic hypotension). The symptom burden in patients on maintenance hemodialysis is high and includes physical symptoms related to fluid shifts . While requiring prompt intervention (e.g., Trendelenburg position, fluid bolus, reducing ultrafiltration rate), it is an expected complication and does not immediately suggest a catastrophic event like the correct answer. The patient is stable enough to respond to initial nursing measures.

2. Access site with slight redness and warmth
This finding suggests a localized infection or inflammation of the vascular access site. A central venous catheter is a direct portal for pathogens, and complications like endocarditis are a known risk following Permcath insertion ^[4]. While this requires attention, including further assessment, culturing, and possibly antibiotic administration, a localized finding without systemic symptoms (fever, chills) is not an immediate, seconds-to-minutes life threat compared to an acute cardiopulmonary event.

4. Muscle cramping in the lower extremities
Muscle cramps are a frequent and painful symptom experienced by patients on hemodialysis, often related to rapid electrolyte shifts and fluid removal. The study on symptom burden confirms that adults on maintenance hemodialysis experience multiple physical symptoms . Nursing interventions include stretching the affected muscle, applying heat, and adjusting the dialysate sodium concentration or ultrafiltration rate. This is a comfort and safety issue but is the lowest priority when a potential air embolism or pneumothorax is occurring.
