A nurse in the emergency department is assessing a client who has internal injuries from a car crash. The client is disoriented to time and place, diaphoretic, and his lips are cyanotic. The nurse should anticipate which of the following findings as an indication of hypovolemic shock?
Widening pulse pressure
Increased heart rate
Increased deep tendon reflexes
Pulse oximetry 96%
The Correct Answer is B
Choice A Reason: This is incorrect. Widening pulse pressure is not a sign of hypovolemic shock, but rather of increased intracranial pressure or aortic regurgitation. Hypovolemic shock causes narrowing pulse pressure due to decreased stroke volume and increased peripheral resistance.
Choice B Reason: This is correct. Increased heart rate is a sign of hypovolemic shock, as the body tries to compensate for the decreased blood volume and cardiac output by increasing the heart rate and contractility.
Choice C Reason: This is incorrect. Increased deep tendon reflexes are not a sign of hypovolemic shock, but rather of hyperreflexia or tetany. Hypovolemic shock causes decreased deep tendon reflexes due to reduced perfusion and oxygenation of the muscles and nerves.
Choice D Reason: This is incorrect. Pulse oximetry 96% is not a sign of hypovolemic shock, but rather of normal oxygen saturation. Hypovolemic shock causes decreased pulse oximetry due to hypoxia and impaired gas exchange.

Correct Answer is D
Explanation
Choice a) is incorrect because elevating the client’s feet is not the priority action for a hypotensive client. Elevating the client’s feet may help increase the venous return to the heart, but it may also compromise the respiratory status of a client who has esophageal varices and is at risk of aspiration.
Choice b) is incorrect because administering a unit of packed RBCs is not the priority action for a hypotensive client. Administering a unit of packed RBCs may help increase the oxygen-carrying capacity of the blood, but it may also increase the blood viscosity and pressure, which can worsen the bleeding from the esophageal varices.
Choice c) is incorrect because initiating a dopamine IV infusion for the client is not the priority action for a hypotensive client. Initiating a dopamine IV infusion may help increase the blood pressure and cardiac output, but it may also cause vasoconstriction and tachycardia, which can increase the risk of hemorrhage and arrhythmias.
Choice d) is correct because increasing the client’s IV fluid rate is the priority action for a hypotensive client. Increasing the client’s IV fluid rate may help restore the intravascular volume and perfusion, which can prevent shock and organ damage. Increasing the client’s IV fluid rate may also dilute the blood and reduce its viscosity and pressure, which can decrease the bleeding from the esophageal varices.
Correct Answer is C
Explanation
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.
