What is the significance of elevated serum levels of troponin?
This intracellular substance can leak into the blood with cardiac cellular injury or death.
Elevated serum levels of troponin occur because of sustained glycogenolysis.
This substance is elevated when a patient has acute tubular necrosis.
Serum elevation of this acute phase reactant occurs because of tissue injury.
The Correct Answer is A
Choice A rationale
Elevated serum levels of troponin indicate cardiac cellular injury or death. Troponin is a protein released into the bloodstream when heart muscle cells are damaged, such as during a myocardial infarction.
Choice B rationale
Sustained glycogenolysis does not cause elevated troponin levels. Glycogenolysis is the breakdown of glycogen to glucose, primarily occurring in the liver and muscles, not related to troponin release.
Choice C rationale
Acute tubular necrosis does not elevate troponin levels. This condition affects the renal tubules and is typically indicated by elevated creatinine and BUN levels.
Choice D rationale
Troponin is not an acute phase reactant. Acute phase reactants are proteins whose levels change in response to inflammation, such as C-reactive protein (CRP), not troponin.

Correct Answer is ["A","B","E","F"]
Explanation
Choice A rationale
The tripod position helps to improve breathing by allowing the diaphragm to expand more effectively. This position reduces the work of breathing and helps to increase lung capacity, which is beneficial for patients with emphysema.
Choice B rationale
Pursed lip breathing is a technique that helps to keep the airways open longer, allowing more air to escape and reducing the work of breathing. This method helps to improve ventilation and oxygenation in patients with emphysema.
Choice C rationale
Staying current with yearly vaccinations is important for overall health, but it is not a specific strategy for better breathing in emphysema patients. Vaccinations help prevent respiratory infections, which can exacerbate emphysema symptoms.
Choice D rationale
Taking an antihistamine every day is not a recommended strategy for better breathing in emphysema patients. Antihistamines are typically used to treat allergies and may have side effects that could worsen breathing difficulties.
Choice E rationale
Inhaling slowly and deeply helps to maximize lung expansion and improve oxygenation. This technique can help to reduce shortness of breath and improve overall breathing efficiency in patients with emphysema.
Choice F rationale
Sleeping with 2 pillows to prop oneself up helps to reduce the work of breathing by preventing the diaphragm from being compressed. This position can help to improve breathing and reduce shortness of breath during sleep.
Choice G rationale
Measuring peak flow is a useful tool for monitoring lung function, but it is not a specific strategy for better breathing in emphysema patients. Peak flow measurements can help to track the progression of the disease and adjust treatment plans accordingly.
Choice H rationale
Taking a leukotriene inhibitor every day is not a recommended strategy for better breathing in emphysema patients. Leukotriene inhibitors are typically used to treat asthma and may not be effective for emphysema.
Correct Answer is A
Explanation
Choice A rationale
Hypersplenism is a condition often associated with cirrhosis, where the spleen becomes overactive. This leads to the destruction of blood cells, causing anemia (low red blood cells), leukopenia (low white blood cells), and thrombocytopenia (low platelets).
Choice B rationale
Peptic ulcer disease primarily affects the stomach and duodenum, leading to ulcers and bleeding. It does not typically cause anemia, leukopenia, and thrombocytopenia in the context of cirrhosis.
Choice C rationale
Cholecystitis is the inflammation of the gallbladder, usually due to gallstones. It does not cause the blood cell abnormalities seen in cirrhosis.
Choice D rationale
Esophageal varices are swollen veins in the esophagus that develop due to portal hypertension in cirrhosis. While they can cause bleeding, they do not directly cause anemia, leukopenia, and thrombocytopenia.
