A nurse is helping to triage a group of clients at a mass casualty incident who were involved in an explosion at a local factory. Which of the following clients should the nurse tag to be the priority for care?

The correct answer is: d. Brachial pulse in the right arm.

Choice A reason: Palpating the radial pulse in the right arm is not the most appropriate choice following a cardiac catheterization with a left antecubital insertion site. While it is contralateral to the insertion site, the brachial pulse is preferred over the radial pulse for assessing circulation in the arm, as it is more proximal and can provide a better indication of arterial flow from the catheterization site.

Choice B reason: The radial pulse in the left arm is the correct choice because it evaluates distal circulation in the affected limb. Since the catheterization was performed through the left antecubital fossa, it is crucial to monitor blood flow further down in the arm. Palpating the radial pulse helps detect early signs of compromised perfusion, such as diminished pulse strength. Evidence-based guidelines from clinical sources highlight the importance of distal pulse assessment post-catheterization.

Choice C reason: Palpating the brachial pulse in the left arm is also not recommended. Since the catheterization was performed on the left side, there is a risk of arterial occlusion or spasm, which could affect the accuracy of the pulse assessment in the left arm.

Choice D reason: The brachial pulse in the right arm does not provide relevant information about the left arm’s vascular status post-catheterization. Since the right arm was not affected by the procedure, its pulse does not indicate possible complications in the left arm. Clinical assessment should focus on detecting perfusion issues in the limb where the catheter was inserted. Best practices recommend prioritizing the evaluation of circulation in the affected extremity.

Choice A: Check the tubing connections for leaks is not an action that the nurse should take. Leaks in the tubing connections can cause continuous or intermitent bubbling in the water seal chamber, not in the suction control chamber. The water seal chamber is the part of the closed chest drainage system that prevents air from entering the pleural space and allows air to escape from the chest tube. The nurse should check the tubing connections for leaks if there is bubbling in the water seal chamber and tighten them if necessary.

Choice B: Check the suction control outlet on the wall is not an action that the nurse should take. The suction control outlet on the wall is the source of negative pressure that helps drain fluid and air from the pleural space and maintain a patent chest tube. The suction control chamber is the part of the closed chest drainage system that regulates the amount of negative pressure applied to the chest tube. The nurse should check the suction control outlet on the wall if there is no bubbling in the suction control chamber and adjust it as prescribed.

Choice C: Continue to monitor the client's respiratory status is an action that the nurse should take. Slow, steady bubbling in the suction control chamber is an expected finding that indicates that the suction is working properly and that there are no leaks in the system. The nurse should continue to monitor the client's respiratory status and assess for signs of respiratory distress, such as dyspnea, tachypnea, cyanosis, or decreased oxygen saturation.

Choice D: Clamping the chest tube is not an action that the nurse should take. Clamping the chest tube can cause a tension pneumothorax, which is a life-threatening condition characterized by a buildup of air in the pleural space that compresses the lung and shifts the mediastinum. The nurse should only clamp the chest tube temporarily and briefly for specific purposes, such as changing or troubleshooting the drainage system, or as prescribed by the provider.
