Question 1 of 5
On postoperative day 7 following hepatic transplant, the patient evidences signs and symptoms of acute rejection, confirmed by histologic examination. The AGACNP knows that first-line treatment of acute rejection consists of
Correct Answer: D
Rationale: The first-line treatment for acute rejection following hepatic transplant is high-dose corticosteroids, such as methylprednisolone. This is because corticosteroids have potent anti-inflammatory and immunosuppressive effects that can help suppress the immune response causing rejection. Cyclosporine, azathioprine, and sirolimus are also commonly used immunosuppressive medications in transplant patients, but in this case of acute rejection, the immediate treatment of choice is methylprednisolone.
Question 2 of 5
K. W. is a 50-year-old woman who presents for surgical resection of the liver for treatment of metastatic colon cancer. Preoperatively, the surgeon tells her that he is planning to remove 50 to 75 of her liver. The patient is concerned that she will not be able to recover normal liver function with that much removed. The AGACNP counsels her that
Correct Answer: B
Rationale: The liver is known for its remarkable ability to regenerate. Major regeneration can occur within 10 days after partial hepatectomy (liver resection) as a compensatory mechanism. The process is typically complete within 5 weeks. This regenerative capacity allows for safe removal of a significant portion of the liver for procedures such as liver resection for cancer. The remaining liver tissue is able to rapidly proliferate and restore normal liver function. The patient should be reassured that even with 50 to 75% of her liver being removed, she can expect a significant amount of liver function recovery postoperatively.
Question 3 of 5
Jake is a 32-year-old patient who is recovering from major abdominal surgery and organ resection following a catastrophic motor vehicle accident. Due to the nature of his injuries, a large portion of his jejunum had to be resected. In planning for his recovery and nutritional needs, the AGACNP considers that
Correct Answer: B
Rationale: The jejunum is the primary site for absorption of nutrients, including vitamin B12. Resection of a large portion of the jejunum can lead to malabsorption of vitamin B12, as this nutrient is primarily absorbed in the distal ileum but also partially absorbed in the jejunum. Thus, Jake is at significant risk for B12 absorption problems following his surgery, and close monitoring and potential supplementation may be needed to address this issue.
Question 4 of 5
P. T. is a 58-year-old female who is admitted with chest pain and shortness of breath and is found to have a large pulmonary embolus. Her systolic blood pressure is falling, and a diagnosis of obstructive shock is made. Cardiac pressure would likely demonstrate
Correct Answer: B
Rationale: Obstructive shock, such as in this case of a large pulmonary embolus causing obstructive shock, results in a sudden increase in right ventricular afterload due to obstruction of blood flow. This leads to right heart failure and decreased left ventricular preload, ultimately resulting in decreased cardiac output. The elevated right-sided pressures will be reflected by elevated right atrial and ventricular pressures, while the left ventricular pressures will be decreased due to decreased preload. This commonly leads to a situation known as acute cor pulmonale, where the right heart becomes dilated and dysfunctional in response to the increased afterload.
Question 5 of 5
With respect to tumor nomenclature, the AGACNP knows that the term carcinoma describes
Correct Answer: A
Rationale: The term "carcinoma" specifically refers to malignant neoplasms that arise from epithelial cells. Epithelial cells are the cells that line the internal and external surfaces of the body. Carcinomas account for the majority of all cancers and can occur in various organs such as the skin, lungs, breasts, colon, and prostate, among others. Carcinomas are characterized by their ability to invade surrounding tissues and potentially metastasize to distant sites in the body. Therefore, option D is the correct choice when describing what the term "carcinoma" signifies in tumor nomenclature.
