Answer to Question 1

D
Ideally surgery takes place 4 to 6 weeks after the completion of radiation treatments to avoid wound-healing problems. The patient with cancer may have radiotherapy before surgery to reduce the size of a cancerous tumor to remove it surgically. Radiation causes fibrosis and vascular scarring in the radiated area. This causes tissues to become fragile and poorly oxygenated, increasing the risk for wound infection.

Answer to Question 2

C
Pregnancy causes changes in ventilation. As the fetus grows during pregnancy, the greater size of the uterus pushes abdominal contents up against the diaphragm. During the last trimester of pregnancy the inspiratory capacity declines, resulting in dyspnea on exertion and increased fatigue. Letting the nurse know immediately and applying oxygen are not needed because this is a normal finding. Making a note of it on the chart does not address the patient's need.
