The nurse explains to the patient that blood pressure measures
The amount of pressure exerted by the veins and arteries on the heart
The amount of blood volume within the blood vessels
The amount of resistance within the veins during heart contraction
The amount of force being placed on arteries by blood
The Correct Answer is D
A. The amount of pressure exerted by the veins and arteries on the heart.: This is not accurate. Blood pressure specifically measures the force exerted by blood on the walls of arteries, not veins, and not the pressure they exert on the heart.
B. The amount of blood volume within the blood vessels.: This is incorrect. Blood pressure is related to blood volume, but it specifically measures the force against the arterial walls.
C. The amount of resistance within the veins during heart contraction.: Blood pressure refers to arterial pressure, not venous resistance.
D. The amount of force being placed on arteries by blood.: This is correct. Blood pressure measures the force of blood pushing against the walls of the arteries as the heart pumps blood through the circulatory system.

Correct Answer is ["A","B","C"]
Explanation
A. Computed tomography: CT angiography can visualize the arteries and detect blockages or narrowing, making it useful in diagnosing peripheral arterial disease (PAD).
B. Duplex ultrasound: This test combines traditional ultrasound with Doppler to assess blood flow and the structure of blood vessels, which is useful for diagnosing PAD by identifying areas of reduced blood flow or blockages.
C. Ankle-brachial index: The ankle-brachial index (ABI) is a non-invasive test that compares the blood pressure in the ankle with the blood pressure in the arm to detect reduced blood flow in the legs, indicative of PAD.
D. Troponin T: Troponin T is a biomarker used to diagnose myocardial infarction (heart attack) and is not relevant for diagnosing PAD, which involves peripheral arteries.
E. Electrocardiogram: An electrocardiogram (ECG) measures the electrical activity of the heart and is used to diagnose cardiac issues, not peripheral artery disease.
Correct Answer is ["A","C","E"]
Explanation
A. Monitor blood glucose levels: Patients with diabetes need to keep their blood glucose levels under control to prevent complications, including those that can exacerbate hypertension or lead to cardiovascular problems.
B. Lifestyle modifications and medication adherence will not prevent blindness: This is incorrect. Proper management of diabetes through lifestyle changes and medication adherence can help prevent complications like diabetic retinopathy, which can lead to blindness.
C. Lifestyle modifications can prevent strokes: Effective management of diabetes and hypertension through lifestyle changes (diet, exercise, smoking cessation) can significantly reduce the risk of strokes and other cardiovascular events.
D. End organ damage is inevitable because of microvascular changes that occur: This is misleading. While microvascular changes are a risk in diabetes, proper management and lifestyle modifications can greatly reduce the risk and progression of end-organ damage.
E. Take medications as ordered: Adherence to prescribed medications is crucial for controlling both blood glucose and blood pressure, reducing the risk of complications such as stroke, heart disease, and kidney damage.
