Postoperative Phase
Postoperative Phase ( 9 Questions)
A nurse is monitoring a patient's temperature after surgery. The patient has a fever of 38.5°C (101.3°F) and chills. What is the most likely cause of the fever?
Atelectasis is the collapse of alveoli in the lungs, which can impair gas exchange and cause hypoxia. It can occur after surgery due to anesthesia, pain, or immobility. However, atelectasis does not usually cause fever and chills, unless it is complicated by pneumonia.
Dehydration is the loss of fluid and electrolytes from the body, which can affect blood pressure, heart rate, and kidney function. It can occur after surgery due to blood loss, vomiting, or inadequate intake. However, dehydration does not usually cause fever and chills, unless it is associated with infection or heat stroke.
Inflammation is the body's response to tissue injury or infection, which involves increased blood flow, swelling, pain, and heat. It can occur after surgery as part of the normal healing process. However, inflammation does not usually cause fever and chills, unless it is severe or systemic.
Infection is the invasion and multiplication of microorganisms in the body, which can trigger an immune response and cause inflammation, fever, and chills. It can occur after surgery due to contamination of the surgical site, catheters, or intravenous lines. Infection is the most likely cause of fever and chills in a postoperative patient.
Choice A reason:
Atelectasis is the collapse of alveoli in the lungs, which can impair gas exchange and cause hypoxia. It can occur after surgery due to anesthesia, pain, or immobility. However, atelectasis does not usually cause fever and chills, unless it is complicated by pneumonia.
Choice B reason:
Dehydration is the loss of fluid and electrolytes from the body, which can affect blood pressure, heart rate, and kidney function. It can occur after surgery due to blood loss, vomiting, or inadequate intake. However, dehydration does not usually cause fever and chills, unless it is associated with infection or heat stroke.
Choice C reason:
Inflammation is the body's response to tissue injury or infection, which involves increased blood flow, swelling, pain, and heat. It can occur after surgery as part of the normal healing process. However, inflammation does not usually cause fever and chills, unless it is severe or systemic.
Choice D reason:
Infection is the invasion and multiplication of microorganisms in the body, which can trigger an immune response and cause inflammation, fever, and chills. It can occur after surgery due to contamination of the surgical site, catheters, or intravenous lines. Infection is the most likely cause of fever and chills in a postoperative patient.
