To prevent the most common serious complication of peritoneal dialysis, it is important for the nurse to:

Choice A reason: Medicating the patient for pain is not the most appropriate immediate action in this situation. While pain management is important, the primary concern should be addressing the significant changes in heart rate and blood pressure, which may indicate a more serious underlying issue.

Choice B reason: Allowing the patient to rest quietly is not the appropriate response to the noted changes in vital signs. The increase in heart rate and drop in blood pressure are signs that require immediate investigation and intervention, rather than passive observation.

Choice C reason: Assessing the patient for bleeding is the most appropriate action. The increase in heart rate and decrease in blood pressure following an angioplasty procedure are concerning for potential bleeding or hemorrhage, especially if the patient has an intra-arterial line. Quick assessment and intervention are crucial to address any bleeding and stabilize the patient's condition.

Choice D reason: Documenting the findings in the chart is necessary, but it should not be the immediate priority. The nurse must first assess and address the potential cause of the changes in vital signs, such as bleeding, before documenting the events.

Choice A reason: Carbon monoxide poisoning occurs when carbon monoxide binds to hemoglobin, preventing oxygen from binding and leading to hypoxia. Symptoms include headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. However, a hoarse voice and a brassy cough are not typical symptoms of carbon monoxide poisoning. These symptoms are more indicative of an inhalation injury due to direct thermal or chemical damage to the airway.

Choice B reason: Pulmonary edema refers to fluid accumulation in the lungs, which can cause difficulty breathing, a feeling of suffocating or drowning, and a cough that produces frothy sputum. Although pulmonary edema can occur after significant burn injuries due to fluid resuscitation or other complications, the specific symptoms of a hoarse voice and brassy cough are more suggestive of an inhalation injury than pulmonary edema.

Choice C reason: An inhalation injury is

The correct answer. This type of injury occurs when a patient inhales smoke, hot gases, or toxic chemicals during a fire. Symptoms can include a hoarse voice, brassy cough, stridor, and respiratory distress. The hoarseness and brassy cough are classic signs of damage to the upper airway due to the inhalation of hot gases or smoke, leading to swelling and irritation of the airway tissues.

Choice D reason: Bacterial pneumonia is an infection of the lungs that can cause symptoms such as fever, chills, cough with phlegm, shortness of breath, and chest pain. While pneumonia can develop as a secondary complication in burn patients, the immediate symptoms of a hoarse voice and brassy cough are more indicative of an inhalation injury rather than bacterial pneumonia.
