What is the significance of elevated serum levels of troponin?

A.

This intracellular substance can leak into the blood with cardiac cellular injury or death.

B.

Elevated serum levels of troponin occur because of sustained glycogenolysis.

C.

This substance is elevated when a patient has acute tubular necrosis.

D.

Serum elevation of this acute phase reactant occurs because of tissue injury.

Answer and Explanation

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

Explanation

Choice A rationale

Sepsis is a systemic inflammatory response to infection, often characterized by fever (temperature of 38°C or higher) and tachycardia (heart rate of 120 beats per minute or higher). These symptoms indicate the body’s response to a severe infection.

Choice B rationale

Hypovolemic shock is caused by significant fluid loss, leading to decreased blood volume and perfusion. It typically presents with hypotension and tachycardia, but not necessarily fever.

Choice C rationale

Myocardial infarction (heart attack) is characterized by chest pain, shortness of breath, and other symptoms, but fever and tachycardia are not primary indicators.

Choice D rationale

Pulmonary embolism involves a blockage in the pulmonary arteries, leading to symptoms such as sudden shortness of breath, chest pain, and rapid heart rate, but not typically fever.

Correct Answer is B

Explanation

Choice A rationale

Administering sodium polystyrene sulfonate helps to lower potassium levels by exchanging sodium ions for potassium ions in the intestines. However, it is not the first intervention because it takes time to work and does not address the immediate risk of cardiac arrhythmias caused by hyperkalemia.

Choice B rationale

Monitoring the client’s cardiac rhythm is the first intervention because hyperkalemia can cause life-threatening cardiac arrhythmias. Continuous cardiac monitoring allows for the early detection and treatment of these arrhythmias, which is crucial for the client’s safety.

Choice C rationale

Restricting dietary potassium intake is an important long-term management strategy for hyperkalemia, especially in clients with chronic kidney disease. However, it does not address the immediate risk of cardiac arrhythmias and is not the first intervention.

Choice D rationale

Preparing the client for hemodialysis is a definitive treatment for hyperkalemia, especially in clients with chronic kidney disease. However, it is not the first intervention because it takes time to arrange and initiate dialysis. Immediate cardiac monitoring is necessary to manage the acute risk of arrhythmias.
