Glucagon is a hormone that stimulates the liver to release glucose from glycogen stores or from gluconeogenesis. However, when the hepatocytes are damaged by alcoholism or other causes of hepatic failure, glucagon is ineffective because the liver cannot respond to its signal. Glucagon administration is contraindicated for hypoglycemic patients with hepatic failure because it will not raise their blood glucose levels and may worsen their acidosis and electrolyte imbalance123

A patient with acetaminophen overdose is at risk for acute liver failure, which can lead to coagulopathy. This condition is often marked by an increased International Normalized Ratio (INR) due to impaired synthesis of clotting factors in the liver. Decreasing level of consciousness can also result from hepatic encephalopathy, a complication of liver failure. References: = CCRN Exam Handbook and AACN's Certification Review Course materials.

For a patient with unstable angina, the major goal of treatment is to decrease myocardial oxygen consumption. This can be achieved by reducing heart rate, blood pressure, and myocardial contractility to lessen the workload on the heart and reduce the demand for oxygen. This helps in preventing further ischemia and potential myocardial infarction. Treatment strategies may include the use of medications such as beta-blockers, nitrates, and calcium channel blockers, which all help in decreasing the oxygen demand of the heart.References: = CCRN Exam Handbook, page 10
