A nurse is caring for two patients who had a coronary artery stent placed yesterday.
What medication should the nurse expect to administer based on the patients’ daily medication administration record?
Clopidogrel
Ibuprofen
Dipyridamole
Acetaminophen
Acetaminophen
The Correct Answer is A
Choice A rationale:
Clopidogrel is an antiplatelet medication that is essential for preventing blood clots from forming within coronary artery stents. It works by inhibiting the binding of adenosine diphosphate (ADP) to its receptors on platelets, thereby reducing platelet aggregation. This is crucial following stent placement because the stent itself can act as a trigger for platelet activation and clotting. By suppressing platelet function, clopidogrel helps to maintain blood flow through the stented artery and reduces the risk of stent thrombosis, a potentially life-threatening complication.
Here's a detailed explanation of why the other choices are incorrect:
Choice B: Ibuprofen
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is primarily used to treat pain and inflammation.
It does not have significant antiplatelet effects and is not typically used for the prevention of stent thrombosis.
While it might be prescribed for pain management after stent placement, it would not be the primary medication expected on the daily medication administration record for this purpose.
Choice C: Dipyridamole
Dipyridamole is an antiplatelet medication, but it is not as potent as clopidogrel and is not considered the first-line agent for preventing stent thrombosis.
It might be used in combination with clopidogrel in certain cases, but it would not be the sole antiplatelet medication expected on the daily medication administration record.
Choice D: Acetaminophen
Acetaminophen is a pain reliever and fever reducer.
It does not have any antiplatelet effects and would not be used to prevent stent thrombosis.
It might be prescribed for pain or fever after stent placement, but it would not be the primary medication expected on the daily medication administration record for this purpose.

Correct Answer is ["A","B"]
Explanation
Choice A rationale:
Enlarged waist circumference is a significant risk factor for metabolic syndrome. Excess abdominal fat, particularly visceral fat that accumulates around the organs, is strongly linked to insulin resistance, a hallmark of metabolic syndrome.
Visceral fat cells are metabolically active, releasing inflammatory substances and free fatty acids that can impair insulin's ability to regulate blood sugar levels. This leads to elevated blood glucose levels, a key feature of metabolic syndrome.
Research consistently demonstrates a strong correlation between waist circumference and metabolic syndrome. Studies have shown that even a modest increase in waist circumference can significantly increase the risk of developing metabolic syndrome.
Waist circumference is a simple and non-invasive measurement that can be used to assess abdominal obesity and identify individuals at risk for metabolic syndrome.
Choice B rationale:
Elevated systolic blood pressure (greater than 130 mmHg) is another key risk factor for metabolic syndrome. High blood pressure, also known as hypertension, is a major risk factor for heart disease, stroke, and other cardiovascular complications.
Multiple mechanisms contribute to the link between hypertension and metabolic syndrome:
Insulin resistance can lead to increased sodium retention by the kidneys, which can raise blood pressure.
Excess weight and obesity can also contribute to hypertension by increasing blood volume and placing strain on the heart.
Metabolic syndrome is often associated with chronic inflammation, which can damage blood vessels and further contribute to hypertension. Choice C rationale:
Decreased triglyceride level is not a risk factor for metabolic syndrome. In fact, elevated triglycerides are one of the diagnostic criteria for metabolic syndrome.
Triglycerides are a type of fat found in the blood. High levels of triglycerides can contribute to the buildup of plaque in the arteries, increasing the risk of heart disease and stroke.
Choice D rationale:
Elevated HDL levels are not a risk factor for metabolic syndrome. HDL cholesterol, often referred to as "good" cholesterol, helps to remove excess cholesterol from the bloodstream and protect against heart disease.
Low HDL levels are a common feature of metabolic syndrome and contribute to its associated cardiovascular risks.
Correct Answer is D
Explanation
Choice A rationale:
Asking the patient to lift up is not appropriate in this situation. It could disturb the clot that has formed at the puncture site and worsen the bleeding. Additionally, it could cause discomfort or pain to the patient.
It's crucial to prioritize actions that address the bleeding and ensure patient safety.
Choice B rationale:
While assessing the groin site is important to identify the source of bleeding, it's not the priority action.
In a case of significant blood loss, immediate assistance is necessary to control the bleeding and prevent further complications.
Delaying the call for help could compromise the patient's hemodynamic stability and lead to shock.
Choice C rationale:
Obtaining vital signs provides valuable information about the patient's condition, but it should not take precedence over calling for help in a case of active bleeding.
Timely intervention to control the bleeding is crucial to prevent hemodynamic instability and potential shock.
Choice D rationale:
Calling for help is the priority action because it ensures prompt assistance from other healthcare professionals.
This allows for a coordinated response to manage the bleeding effectively, initiate appropriate interventions, and closely monitor the patient's condition.
Early intervention is essential to prevent further blood loss, maintain hemodynamic stability, and optimize patient outcomes.
