A client who had gastric bypass surgery 3 days ago is admitted to the intensive care unit (ICU) with shortness of breath and chest pain. The client has a 100% nonrebreather mask with an oxygen saturation of 88%. Which intervention should the nurse implement?

A. Suture removal kit. A suture removal kit is used when the chest tube is ready for removal, but it is not necessary to keep at the bedside during routine chest tube management. The priority is ensuring emergency supplies are available if the tube becomes dislodged.
B. Suction catheter. A suction catheter is used to remove secretions from the airway but is not essential for managing a chest tube. Chest drainage systems function independently to remove air or fluid, and routine suctioning is not required for chest tube management.
C. Sterile gauze dressing. If the chest tube accidentally dislodges, an occlusive dressing (such as sterile gauze with petroleum jelly) should be applied immediately to prevent air from re-entering the pleural space, which could lead to a tension pneumothorax. Keeping sterile gauze at the bedside ensures rapid intervention in case of accidental chest tube removal.
D. Sterile piston syringe. A sterile piston syringe is used for irrigating wounds or suctioning secretions, but it is not necessary for chest tube management. The closed drainage system should never be manually flushed unless specifically ordered by a healthcare provider.

A. Narrowed pulse pressure, presence of 3+ femoral pulses, apneic episodes. Narrowed pulse pressure is consistent with hypovolemic shock, but 3+ femoral pulses are not expected, as shock leads to weak, thready pulses due to reduced perfusion. Apneic episodes typically occur in the late stages of shock, not in the early or progressive stages.
B. Widening pulse pressure, muffled heart sounds, presence of atrial gallop. A widening pulse pressure and muffled heart sounds are more indicative of cardiac tamponade, not hypovolemic shock. Hypovolemic shock is characterized by a narrowing pulse pressure due to a drop in systolic blood pressure while diastolic pressure remains relatively stable.
C. Increased heart rate, lowered systolic reading, peripheral extremity mottling. Tachycardia is an early compensatory response to hypovolemia as the body attempts to maintain cardiac output. As shock progresses, systolic blood pressure drops due to inadequate circulating volume. Peripheral extremity mottling occurs as the body shunts blood to vital organs, reducing perfusion to the skin. These signs are characteristic of progressive hypovolemic shock.
D. Irregular heart rate, elevated diastolic reading, increased respiratory rate. An irregular heart rate is not a primary indicator of hypovolemic shock. While respiratory rate increases in response to decreased oxygen delivery, an elevated diastolic reading is uncommon, as diastolic pressure tends to stay stable or decrease slightly with ongoing hypovolemia.
