Computed tomography

Duplex ultrasound

Ankle-brachial index

Troponin T

Electrocardiogram

Answer and Explanation

Correct Answer : A,B,C

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 C

Explanation

A. Provide names of support groups: While support groups can offer emotional and educational support, they do not address the immediate financial barrier to obtaining necessary medications.
B. Schedule an annual physical examination: Regular check-ups are important, but they do not directly address the issue of medication affordability and access to care.
C. Refer the patient to a free clinic: Free clinics often provide low-cost or no-cost medications and healthcare services, which can help the patient access the necessary treatments and follow-up care.
D. Refer the patient for financial assistance: Financial assistance programs can be helpful, but they might take time to apply and be approved. Immediate referral to a free clinic can provide more immediate support.

A. Obtain an electrocardiogram (ECG) exam B. Obtain intravenous access C. Administer 2 L of oxygen per nasal cannula D. Obtain a rectal temperature

Correct Answer is C

Explanation

A. Obtain an electrocardiogram (ECG) exam: While an ECG is important to assess cardiac status, it is not the immediate priority compared to addressing the low oxygen saturation.
B. Obtain intravenous access: IV access is important for administering medications and fluids but does not take precedence over addressing hypoxia.
C. Administer 2 L of oxygen per nasal cannula: This is correct. The priority is to improve oxygenation since hypoxia can exacerbate neurological damage in a stroke patient. An SpO2 of 88% is low and requires immediate correction to prevent further complications.
D. Obtain a rectal temperature: Temperature assessment is not as urgent as addressing the immediate need for oxygen to improve SpO2 levels.
