A nurse is caring for a client who has a disposable three-chamber chest tube in place. Which of the following findings should indicate to the nurse that the client is experiencing a complication?
Continuous bubbling in the water-seal chamber
Occasional bubbling in the water-seal chamber
Fluctuations in the fluid level in the water-seal chamber
Constant bubbling in the suction-control chamber
The Correct Answer is A
Choice A Reason: Continuous bubbling in the water-seal chamber indicates an air leak in the chest tube system, which can compromise the drainage of air and fluid from the pleural space and impair lung expansion.
Choice B Reason: Occasional bubbling in the water-seal chamber is normal and expected, as it indicates that air is being removed from the pleural space.
Choice C Reason: Fluctuations in the fluid level in the water-seal chamber are normal and expected, as they reflect changes in intrathoracic pressure during inspiration and expiration.
Choice D Reason: Constant bubbling in the suction-control chamber is normal and expected, as it indicates that suction is being applied to the chest tube system.

Correct Answer is C
Explanation
Choice A: Contacting the provider for further orders is not necessary, because the client has type AB blood, which is compatible with any other blood type. The client can receive type B blood without any adverse reactions.
Choice B: Notifying the blood bank of the discrepancy is not required, because there is no discrepancy. The blood bank sent the correct type of blood for the client, according to their blood type.
Choice C: Administering the blood as ordered is the correct action, because type B blood is compatible with type AB blood. The client will not have any transfusion reactions or complications from receiving this type of blood.
Choice D: Completing an incident report is not appropriate, because there is no incident. The nurse did not make any error or mistake in administering the blood to the client. There is no need to document or report anything unusual.
Correct Answer is A
Explanation
Choice A Reason: This is correct because a pulmonary artery catheter is a device that measures the pressures and flows in the heart and lungs, such as the pulmonary artery pressure, the pulmonary artery wedge pressure, the cardiac output, and the mixed venous oxygen saturation. These parameters reflect the hemodynamic status of the client, which is the balance between the cardiac output and the systemic vascular resistance.
Choice B Reason: This is incorrect because a pulmonary artery catheter does not measure spinal cord perfusion, which is the blood flow to the spinal cord. Spinal cord perfusion can be affected by spinal cord injury, spinal anesthesia, or spinal surgery.
Choice C Reason: This is incorrect because a pulmonary artery catheter does not measure renal function, which is the ability of the kidneys to filter waste products and maintain fluid and electrolyte balance. Renal function can be assessed by urine output, blood urea nitrogen, creatinine, and glomerular filtration rate.
Choice D Reason: This is incorrect because a pulmonary artery catheter does not measure intracranial pressure, which is the pressure inside the skull. Intracranial pressure can be increased by brain injury, stroke, tumor, infection, or hydrocephalus.
