The unlicensed assistive personnel (UAP) notifies the nurse of these vital signs for a client on the medical-surgical unit: temperature 97.6°F, respirations 20, pulse 122, and BP 98/72. Which actions should the nurse do next?

Choice A reason: Elevated sodium level (hypernatremia) is unlikely with high NG drainage, as gastric fluid contains sodium, risking hyponatremia. The large volume (2,500 mL) suggests significant electrolyte loss, particularly potassium, not sodium accumulation, making this an incorrect imbalance to prioritize in this scenario.

Choice B reason: Decreased potassium level (hypokalemia) is a concern with high NG drainage, as gastric fluid contains potassium. Losing 2,500 mL in 6 hours depletes potassium, risking arrhythmias, muscle weakness, and prolonged ileus. Monitoring potassium prevents life-threatening complications, making it the priority in this postoperative client.

Choice C reason: Elevated magnesium level (hypermagnesemia) is not associated with NG drainage, as gastric fluid has minimal magnesium. Excessive drainage leads to losses of potassium and sodium, not magnesium accumulation, making this an incorrect imbalance to prioritize in this client with postoperative ileus.

Choice D reason: Decreased calcium level (hypocalcemia) is less likely, as gastric fluid has low calcium content. Potassium and sodium losses are more significant due to their higher concentrations in gastric secretions, making hypokalemia a greater concern than hypocalcemia in this high-drainage postoperative scenario.

Choice A reason: Rolled gauze and sterile saline are used for general wound care but are inadequate for chest tube emergencies. If a tube dislodges, an occlusive dressing prevents air entry into the pleural space, avoiding pneumothorax, making this choice insufficient for emergency preparedness in chest tube management.

Choice B reason: A petrolatum-impregnated sterile occlusive dressing is critical for chest tube emergencies. If the tube dislodges, it seals the pleural space, preventing air entry and reducing pneumothorax risk. This ensures immediate response to maintain lung function, making it the priority supply for emergency preparedness.

Choice C reason: Suction tubing and Yankauer suction tip clear oral or airway secretions, not chest tube issues. They are irrelevant for emergencies like tube dislodgement, where sealing the pleural space prevents pneumothorax, making this choice inappropriate for chest tube emergency preparedness in this scenario.

Choice D reason: Non-adhesive dressings and tracheostomy tubes are for tracheostomy care, not chest tubes. They do not address emergencies like tube dislodgement, which require an occlusive dressing to prevent air entry, rendering this choice incorrect for chest tube emergency preparedness in this context.
