A nurse is evaluating the central venous pressure (CVP) of a client who has sustained multiple traumas. Which of the following interpretations of a low CVP should the nurse make?
Fluid overload
Intracardiac shunt
Hypovolemia
Left ventricular failure
The Correct Answer is C
Choice A Reason: This is incorrect because fluid overload is a condition of excess fluid volume in the body. A client who has fluid overload is more likely to have a high CVP, which indicates increased pressure in the right atrium and vena cava.
Choice B Reason: This is incorrect because an intracardiac shunt is a condition of abnormal blood flow between the chambers of the heart. A client who has an intracardiac shunt may have a normal or high CVP, depending on the direction and magnitude of the shunt.
Choice C Reason: This is correct because hypovolemia is a condition of low fluid volume in the body. A client who has hypovolemia is more likely to have a low CVP, which indicates decreased pressure in the right atrium and vena cava.
Choice D Reason: This is incorrect because left ventricular failure is a condition of impaired pumping function of the left ventricle. A client who has left ventricular failure may have a normal or high CVP, depending on the degree of backward failure and pulmonary congestion.

Correct Answer is A
Explanation
Choice A Reason: This is correct because a client who is short of breath is in immediate danger, as it indicates a possible respiratory compromise or failure. The nurse should assess the client's oxygen saturation, respiratory rate, and lung sounds, and provide oxygen therapy as needed.
Choice B Reason: This is incorrect because a client who received oral pain medication 30 min ago is not in immediate danger, as it indicates that the client's pain has been managed and the medication has had time to take effect.
Choice C Reason: This is incorrect because a client who is scheduled for an abdominal x-ray and is awaiting transport is not in immediate danger, as it indicates that the client's condition is stable and the diagnostic test is not urgent.
Choice D Reason: This is incorrect because a client who has a prescription for discharge is not in immediate danger, as it indicates that the client's condition has improved and the client is ready to leave the hospital.
Correct Answer is B
Explanation
Choice A Reason: Urine output is not a finding that should decrease with adequate fluid replacement. On the contrary, urine output should increase as the fluid therapy restores the renal perfusion and function. The nurse should monitor the urine output and ensure that it is at least 0.5 mL/kg/hr for adults and 1 mL/kg/hr for children.
Choice B Reason: Heart rate is a finding that should decrease with adequate fluid replacement. A high heart rate is a sign of hypovolemia, which occurs when the burn injury causes fluid loss from the intravascular space. The nurse should monitor the heart rate and expect it to decrease as the fluid therapy replenishes the blood volume and improves the cardiac output.
Choice C Reason: Weight is not a finding that should decrease with adequate fluid replacement. On the contrary, weight may increase as the fluid therapy restores the hydration status and corrects the fluid deficit. The nurse should monitor the weight and compare it with the pre-burn weight to evaluate the fluid balance.
Choice D Reason: Blood pressure is not a finding that should decrease with adequate fluid replacement. On the contrary, blood pressure may increase as the fluid therapy restores the vascular tone and improves the tissue perfusion. The nurse should monitor the blood pressure and expect it to increase as the fluid therapy compensates for the fluid loss.
