aspiration pneumonia; arterial blood gas (ABG)

chronic bronchitis; peak flow

Answer and Explanation

The Correct Answer is D

A. Hypertension may contribute to cardiovascular issues, but it does not typically cause cyanosis or clubbing.

B. Left heart failure often leads to symptoms like dyspnea and fluid retention but does not commonly cause clubbing of the fingers.

C. Aspiration pneumonia may cause respiratory symptoms, but clubbing is more associated with chronic hypoxia, seen in conditions like chronic bronchitis.

D. Chronic bronchitis, often seen in chronic obstructive pulmonary disease (COPD), can cause long-term hypoxia, leading to cyanosis and clubbing of the fingers. A peak flow test can assess respiratory function and airflow limitations associated with chronic bronchitis.

Correct Answer is D

A. Creatine kinase level B. Homocysteine level C. Serum high-density lipoproteins (HDL) D. Serum potassium

Correct Answer is B

Explanation

A. Creatine kinase is an enzyme released when muscle tissue is damaged, often used in diagnosing muscle injuries or heart attacks, not coronary artery disease risk.

B. Elevated homocysteine levels are associated with an increased risk for coronary artery disease as it can damage the blood vessel walls and promote clot formation.

C. High levels of serum high-density lipoproteins (HDL) are protective against coronary artery disease, not a risk factor.

D. Serum potassium is important for cardiovascular health, but it does not directly correlate with coronary artery disease risk.
