AOCNP Surgical Oncology and Perioperative Care 5

Question 1

A patient with stage III melanoma undergoes completion lymph node dissection after a positive sentinel node. Which postoperative complication occurs in up to 40% of patients following inguinal lymphadenectomy?

Accepted Answer

Lymphedema of the lower extremity

Answer

Lymphedema is the most significant long-term complication after inguinal lymphadenectomy, affecting up to 40% of patients and requiring long-term compression therapy.

Question 2

During a laparoscopic colectomy, the anesthesia team notes end-tidal CO2 rising from 38 to 58 mmHg over 20 minutes. The MOST likely cause in this context is:

Accepted Answer

CO2 absorption from pneumoperitoneum

Answer

Hypercarbia during laparoscopic surgery is most commonly caused by CO2 absorption across the peritoneal membrane from pneumoperitoneum, typically managed by increasing minute ventilation.

Question 3

An oncology NP is reviewing a preoperative risk assessment. Which validated scoring tool is used to predict postoperative pulmonary complications in surgical oncology patients?

Accepted Answer

ARISCAT score

Answer

The ARISCAT (Assess Respiratory Risk in Surgical Patients in Catalonia) score predicts postoperative pulmonary complications and guides risk stratification for surgical patients.

Question 4

A patient undergoes left pneumonectomy for central lung squamous cell carcinoma. On postoperative day 2, the patient develops sudden severe dyspnea and the trachea shifts to the right. Which complication has occurred?

Accepted Answer

Cardiac herniation through the pericardial defect

Answer

Cardiac herniation is a rare but immediately life-threatening complication after pneumonectomy when the heart herniates through a pericardial defect, causing sudden cardiovascular collapse and mediastinal shift.

Question 5

In the context of surgical oncology, 'R0 resection' refers to:

Accepted Answer

Removal of all visible tumor with histologically confirmed negative margins

Answer

R0 resection indicates complete tumor removal with no residual microscopic disease at the surgical margins, representing the surgical goal for curative intent.
