The nurse is assessing a client presenting with chest pain and determines that the client's symptoms correlate with angina-type pain, which was provoked by exercise. Which of the following treatments would be prioritized for this client's acute condition?
metoprolol
aspirin
clopidogrel
nitroglycerin
The Correct Answer is D
Angina pectoris occurs when myocardial oxygen demand exceeds oxygen supply, often triggered by physical exertion or stress. This imbalance leads to transient chest pain due to myocardial ischemia without irreversible myocardial damage. Acute management focuses on rapidly relieving ischemia by improving coronary blood flow and reducing cardiac workload. Immediate symptom relief is essential to prevent progression to myocardial infarction.
Rationale:
A. Metoprolol is a beta-blocker that decreases heart rate and myocardial oxygen demand, making it useful for long-term angina management and prevention of episodes. However, it is not the first-line medication for immediate relief of acute anginal pain because it does not act quickly enough to terminate ongoing ischemia. It is more appropriate for chronic control rather than acute symptom resolution.
B. Aspirin is important in acute coronary syndromes because it inhibits platelet aggregation and helps prevent clot formation. However, it does not provide immediate relief of chest pain because it does not directly improve coronary blood flow or reduce myocardial oxygen demand. It is an adjunct therapy rather than the primary agent for acute angina relief.
C. Clopidogrel is an antiplatelet agent used to prevent further thrombus formation in clients with coronary artery disease. It works by inhibiting ADP-induced platelet aggregation but has no immediate effect on chest pain or myocardial oxygen supply-demand balance. It is used for secondary prevention rather than acute symptom management.
D. Nitroglycerin is the priority treatment for acute angina because it rapidly dilates coronary arteries and reduces myocardial oxygen demand. It works by relaxing vascular smooth muscle, improving blood flow to ischemic myocardium, and decreasing preload. This leads to quick relief of chest pain and is the first-line medication for acute anginal episodes.

Explanation
Hemodynamic instability in a postoperative client showing a progressive decline in level of consciousness and urine output can occur as a result of postoperative complications which include fluid volume loss, bleeding, or impaired perfusion leading to decreased cardiac output. Blood pressure trends are critical indicators of circulatory status. A falling blood pressure accompanied by bradycardia, decreased urine output, and altered mental status strongly suggests reduced tissue perfusion and shock-like physiology rather than elevated blood pressure states.
Rationale:
• Hypotension: The client’s blood pressure has dropped significantly from 124/78 mmHg to 88/56 mmHg, indicating decreased vascular perfusion and possible reduced cardiac output. This is supported by worsening mental status, bradycardia, and decreased urine output, which are classic signs of poor systemic perfusion. In postoperative clients, hypotension may result from hypovolemia, bleeding, or distributive causes. The downward trend in vital signs confirms a hypotensive state requiring urgent intervention.
• Hypertension: Hypertension would present with elevated blood pressure readings and is not consistent with the documented trend in this client. Instead of an increase, the client’s blood pressure has progressively decreased to hypotensive levels. Additionally, hypertension would not explain decreased urine output, worsening consciousness, or bradycardia in this context. Therefore, hypertension is not supported by the clinical findings.
Correct Answer is A
Explanation
Liver cirrhosis is a progressive, irreversible condition characterized by fibrosis, scarring, and architectural distortion of liver tissue. It results from long-term liver injury that leads to impaired hepatic function, portal hypertension, and eventual liver failure. Common causes include chronic infection, toxic exposure, and metabolic disease. Identifying major risk factors is essential for prevention, early detection, and management of liver disease progression.
Rationale:
A. Chronic viral hepatitis infections are a major risk factor for the development of liver cirrhosis. Long-standing infection with hepatitis B or hepatitis C causes persistent inflammation and hepatocyte injury, leading to fibrosis and progressive scarring of liver tissue. Over time, this chronic damage disrupts normal liver architecture and function, significantly increasing the risk of cirrhosis and hepatocellular carcinoma.
B. Infrequent alcohol consumption is not a significant risk factor for cirrhosis. While chronic and heavy alcohol use is a well-established cause of liver damage, occasional or infrequent intake does not typically result in the sustained hepatic injury needed to cause cirrhosis. The risk is strongly associated with long-term, excessive alcohol use rather than sporadic consumption.
C. Regular aerobic exercise is not a risk factor for liver cirrhosis and is generally considered protective for overall health. Physical activity helps improve metabolism, reduce fatty liver risk, and support cardiovascular and hepatic health. It does not contribute to liver inflammation or fibrosis.
D. Consuming a low-fat diet is not associated with an increased risk of cirrhosis. In fact, a balanced or low-fat diet may help reduce the risk of nonalcoholic fatty liver disease, which can otherwise progress to cirrhosis if untreated. Dietary fat intake alone, when appropriate, does not cause chronic liver injury.
