Question 1 of 5

A patient presents with chest pain at rest, unrelated to exertion, and not relieved by nitroglycerin. An electrocardiogram (ECG) shows ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: B

Rationale: Unstable angina is characterized by chest pain at rest, which is not relieved by nitroglycerin. The ECG findings in unstable angina typically show ST-segment depression or T-wave inversion. It is considered a medical emergency as it can progress to a myocardial infarction. Stable angina, on the other hand, is chest pain or discomfort that occurs with exertion and is relieved by rest or medications like nitroglycerin. Acute myocardial infarction would typically present with ST-segment elevation on ECG, while Prinzmetal's angina is characterized by transient ST-segment elevation due to coronary artery vasospasm.

Question 2 of 5

A patient with terminal illness expresses a desire to spend quality time with their family but feels guilty for being a burden. How should the palliative nurse respond?

Correct Answer: C

Rationale: In this situation, the most appropriate response for the palliative nurse is to validate the patient's feelings of guilt and offer support to address their concerns. It is important to acknowledge the patient's emotions and help them navigate through their guilt in a compassionate and understanding manner. By validating their feelings, the nurse can create a safe space for the patient to express their concerns and work towards finding solutions to alleviate their guilt. This approach fosters trust and a therapeutic relationship between the patient and the nurse, ultimately promoting emotional well-being and facilitating open communication.

Question 3 of 5

A patient receiving palliative care for end-stage dementia experiences agitation and restlessness. What intervention should the palliative nurse prioritize to address the patient's symptoms?

Correct Answer: C

Rationale: The most appropriate intervention for a patient with end-stage dementia experiencing agitation and restlessness is to create a calm and soothing environment to promote relaxation. Patients with dementia often respond positively to a familiar and tranquil setting, which can help reduce their symptoms of agitation and restlessness. This approach is preferred over administering antipsychotic medications or recommending physical exercise, as these may not be feasible or beneficial for patients in the advanced stages of dementia. Referring the patient to a psychiatrist may not address the immediate need for symptom management and can be considered if other interventions are ineffective. Creating a calm environment, such as dim lighting, soft music, and familiar objects, can help provide comfort and reduce distress for the patient.

Question 4 of 5

A patient receiving palliative care for end-stage liver disease develops hepatic encephalopathy, presenting with confusion and altered mental status. What intervention should the palliative nurse prioritize to manage the patient's symptoms?

Correct Answer: A

Rationale: The most appropriate intervention for managing hepatic encephalopathy in this patient receiving palliative care for end-stage liver disease is to administer lactulose or other ammonia-lowering agents to reduce ammonia levels. Hepatic encephalopathy is believed to be primarily caused by the accumulation of ammonia in the bloodstream due to compromised liver function. Lactulose works by acidifying the gut lumen, which facilitates the excretion of ammonia in the form of ammonium ions. By reducing ammonia levels, hepatic encephalopathy symptoms, such as confusion and altered mental status, can be improved. Initiating other supportive measures like managing precipitating factors, maintaining hydration, and addressing nutritional issues should also be part of the holistic approach in managing hepatic encephalopathy in palliative care. However, addressing the underlying cause by reducing ammonia levels with lactulose is the priority intervention in this scenario.

Question 5 of 5

A patient admitted to the ICU develops acute gastrointestinal bleeding requiring urgent intervention. What intervention should the healthcare team prioritize to manage the patient's bleeding?

Correct Answer: A

Rationale: In a patient with acute gastrointestinal bleeding requiring urgent intervention, the healthcare team should prioritize performing endoscopic hemostasis with mechanical or thermal techniques. Endoscopy allows for direct visualization of the source of bleeding in the gastrointestinal tract, enabling targeted interventions such as clipping, cauterization, or injection of epinephrine to achieve hemostasis. This approach is effective in managing acute bleeds and can help stop the bleeding quickly, reducing the need for more invasive procedures or surgeries. Administering proton pump inhibitors (PPIs) may be considered for acid-related bleeding, but it is not the primary intervention for acute bleeding requiring urgent management. Strict bed rest may not be necessary and can increase the risk of complications such as deep vein thrombosis. Transfusion of fresh frozen plasma may be indicated if there is evidence of coagulopathy, but addressing the bleeding source should be the initial priority to
