The nurse is performing the safety checks prior to initiating a packed red blood cell transfusion for a patient whose blood type is A positive. The nurse observes the unit is AB negative. What is the nurse's best first action?

A. Radiation oncology is focused on the use of radiation therapy to treat cancer. Since the patient has decided not to continue with treatment, this specialty would not be the most appropriate recommendation in this situation.
B.Hospice care is the most appropriate recommendation for a patient with a terminal diagnosis who has chosen to stop curative treatments. This specialty focuses on comfort, pain management, and emotional support for patients with a life expectancy of six months or less. It provides a multidisciplinary team to assist the patient and family during the end-of-life process.
C. Psychiatry may be helpful if the patient is experiencing significant emotional or psychological distress, but it is not the primary specialty needed for a terminal cancer patient who is opting for comfort-focused care.
D.Surgical oncology involves the physical removal of cancerous tumors through operative procedures. Because the patient has decided not to continue with cancer treatment, surgery—which is an invasive form of treatment—is no longer an objective. A surgical consult would not align with the patient’s goal of comfort and the cessation of aggressive medical interventions.

A. The subdivision of pancreatic tumors into endocrine versus exocrine reflects their cell of origin (islet cells versus ductal cells) rather than conveying information about how the cancer behaves in situ or its propensity for local invasion and metastasis

B. Unlike some other cancers (e.g., colorectal cancer), pancreatic cancer does not typically develop from polyps. Most cases of pancreatic cancer develop from the pancreatic ductal cells (the cells lining the ducts of the pancreas), and the disease is typically aggressive and diagnosed at a later stage.

C. Because the pancreas lies deep in the retroperitoneum directly adjacent to major vessels like the superior mesenteric artery and portal vein, tumors often extend into these structures early, contributing to the high rate of advanced disease at diagnosis

D. Pancreatic cancer is not distinguished based on layers. Instead, it is generally categorized based on the type of cells it affects (e.g., ductal cells in exocrine pancreatic cancer). The staging of pancreatic cancer is based on factors like tumor size, lymph node involvement, and metastasis, rather than the layers of the pancreas.
