A patient presents with chest pain that occurs at rest and is relieved by nitroglycerin. An electrocardiogram (ECG) may show transient ST-segment elevation. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: D

Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.

Correct Answer: C

Rationale: Opioid medications are considered the first-line pharmacological treatment for dyspnea in palliative care patients with advanced cancer. Opioids help relieve dyspnea by reducing respiratory drive and the sensation of breathlessness, providing effective symptom management. In this case, addressing the patient's dyspnea with opioid medications would likely also help alleviate their anxiety related to breathlessness. Administering oxygen therapy (choice A) may not be effective at relieving dyspnea in this situation, as dyspnea in advanced cancer patients is often not primarily due to low oxygen levels. Teaching pursed-lip breathing techniques (choice B) and referring the patient to a respiratory therapist for breathing exercises (choice D) may be helpful complementary interventions, but opioid medications should be the priority for symptom management.

Correct Answer: A

Rationale: In a patient with severe abdominal pain due to end-stage pancreatic cancer, the priority intervention to manage their symptoms would be to provide adequate pain relief. Opioid analgesics are the cornerstone of pain management for cancer patients experiencing severe pain. They work by binding to opioid receptors in the central nervous system, thereby reducing the perception of pain. Opioids are highly effective in managing cancer pain, including abdominal pain, and can significantly improve the patient's quality of life by providing relief from distressing symptoms. Therefore, administering opioid analgesics should be the nurse's primary intervention in this case to address the patient's severe abdominal pain. Initiating enteral nutrition, recommending hot compresses, or referring to a gastroenterologist may be relevant interventions depending on the patient's overall care plan but addressing the pain should be the immediate priority in this scenario.

Correct Answer: A

Rationale: The priority intervention in managing acute pancreatitis is to administer intravenous fluids to maintain adequate hydration. Acute pancreatitis can lead to significant fluid loss and dehydration due to factors such as vomiting and third-spacing of fluids into the retroperitoneal space. Adequate hydration helps to optimize perfusion to the pancreas, prevent hypovolemic shock, and support overall organ function. This intervention also aids in flushing out inflammatory mediators and preventing complications such as acute kidney injury. Monitoring fluid status and adjusting the rate of intravenous fluid administration based on the patient's response is crucial in the management of acute pancreatitis. While other interventions such as imaging studies, nutritional support, and gastric acid suppression may be important in managing acute pancreatitis, ensuring adequate hydration is the most critical initial step.

Correct Answer: B

Rationale: In cases of acute intracerebral hemorrhage (ICH) with elevated intracranial pressure (ICP), a significant factor contributing to the elevated ICP is often the mass effect caused by the hematoma within the brain. Performing an emergent craniotomy for hematoma evacuation is a critical intervention to relieve the pressure within the intracranial space, thereby mitigating the risk of herniation and further neurological damage. While other interventions such as hypertonic saline therapy, head-of-bed elevation, and sedative medications may have supporting roles in managing ICP, none address the primary cause of elevated ICP in cases of acute intracerebral hemorrhage as effectively as hematoma evacuation through craniotomy.
