Question 1 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 2 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 3 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.
Question 4 of 5
The AGACNP is going over preoperative information and instructions with a patient who is having a major transverse abdominal procedure tomorrow morning. The patient is very nervous and is asking a lot of questions. The AGACNP prescribes a sleeping agent because he knows that anxiety and sleeplessness may
Correct Answer: C
Rationale: Anxiety and sleeplessness can contribute to the risk of delirium and prolonged length of stay for the patient undergoing a major transverse abdominal procedure. Delirium is a common complication seen in patients who are anxious and sleep-deprived, especially postoperatively. It is important to address these issues preoperatively to help prevent delirium and ensure a smoother recovery process for the patient. By prescribing a sleeping agent, the AGACNP aims to reduce anxiety and promote a good night's sleep, which can ultimately decrease the risk of delirium and lead to better outcomes for the patient.
Question 5 of 5
The AGACNP knows that when managing a patient with acute cardiogenic shock after myocardial infarction, all of the following pharmacologic agents may be used except
Correct Answer: A
Rationale: Anticholinergics are not typically used in the management of acute cardiogenic shock after myocardial infarction. Anticholinergic medications may worsen tachycardia and exacerbate myocardial ischemia by increasing heart rate and myocardial oxygen demand. Therefore, the AGACNP should avoid using anticholinergics in this patient population.
