Question 1 of 5

A patient is admitted with a suspected myocardial infarction. Which cardiac biomarker is most specific for myocardial injury?

Correct Answer: A

Rationale: Troponin is the most specific cardiac biomarker for myocardial injury. Troponin I and Troponin T are proteins released into the bloodstream when there is damage to the heart muscle, making them highly indicative of myocardial infarction. Troponin levels rise within a few hours of cardiac injury, peak within 24-48 hours, and can remain elevated for up to 2 weeks. Troponin is considered the gold standard biomarker for the diagnosis of acute myocardial infarction due to its high specificity and sensitivity for cardiac injury. In contrast, Creatine kinase-MB (CK-MB) and myoglobin are also used in diagnosing myocardial infarction but are less specific than troponin. Brain natriuretic peptide (BNP) is primarily used in heart failure diagnosis and management, and its levels are not specific to myocardial injury.

Question 2 of 5

A patient with a history of cirrhosis is at risk for developing hepatic encephalopathy. Which nursing intervention is most effective in preventing and managing hepatic encephalopathy?

Correct Answer: A

Rationale: Lactulose is the most effective nursing intervention in preventing and managing hepatic encephalopathy in patients with cirrhosis. Lactulose works by promoting the elimination of ammonia in the colon through its laxative effect, thereby reducing ammonia levels in the blood. High ammonia levels are associated with the development of hepatic encephalopathy. By administering lactulose as prescribed, nurses can help reduce the risk of encephalopathy and manage symptoms effectively. Monitoring serum ammonia levels is important in assessing the effectiveness of lactulose therapy, but administering lactulose is the primary nursing intervention in this situation. Dietary protein restriction is also commonly recommended; however, lactulose administration is the most vital intervention in this scenario. Additionally, encouraging increased fluid intake is important for overall liver health but is not as specific to preventing and managing hepatic encephalopathy as administering lactulose.

Question 3 of 5

A patient with a history of chronic kidney disease is prescribed erythropoietin-stimulating agents (ESAs) for anemia management. Which parameter should the nurse monitor closely during ESA therapy?

Correct Answer: B

Rationale: When a patient with chronic kidney disease is prescribed erythropoietin-stimulating agents (ESAs) for anemia management, the parameter that should be monitored closely by the nurse is the hemoglobin levels. Hemoglobin levels indicate the patient's response to ESA therapy and are essential in assessing the effectiveness of the treatment in addressing anemia. Monitoring hemoglobin levels helps ensure that the patient's anemia is controlled within the target range to avoid both the risks of under-treatment (resulting in persistent anemia) and over-treatment (increased risk of adverse outcomes such as hypertension, stroke, or cardiovascular events).

Question 4 of 5

A patient with a history of chronic kidney disease is prescribed phosphate binders. Which instruction should the nurse include in patient education about phosphate binder therapy?

Correct Answer: A

Rationale: The correct instruction that the nurse should include in patient education about phosphate binder therapy is to "Take phosphate binders with meals." Phosphate binders are medications given to patients with chronic kidney disease to help control high phosphate levels in the blood. Taking phosphate binders with meals allows them to bind to the phosphorus present in the food, reducing its absorption in the body. This helps to lower blood phosphate levels effectively. Instructing the patient to take phosphate binders with meals ensures optimal binding of phosphorus from the diet, which is crucial for managing phosphate levels in patients with chronic kidney disease.

Question 5 of 5

A patient is prescribed a benzodiazepine for the management of anxiety. Which instruction should the nurse include in patient education about benzodiazepine therapy?

Correct Answer: B

Rationale: Consuming alcohol while on benzodiazepine therapy can increase the central nervous system depressant effects of benzodiazepines, leading to excessive sedation, respiratory depression, and even overdose. It is important for patients to avoid alcohol to prevent these potential dangerous interactions and to ensure the safe and effective use of their medication.
