A nurse is teaching a patient about coronary artery disease (CAD). Which of the following statements made by the patient demonstrates understanding of the disease?

I understand that CAD is caused by the build up of fat deposits in my arteries

Only people with a family history of heart disease are at risk for CAD.

CAD can be completely cured with a healthy diet and exercise.

I should avoid all physical activity to prevent worsening my CAD.

Answer and Explanation

The Correct Answer is A

A. "I understand that CAD is caused by the buildup of fat deposits in my arteries." CAD is caused by the accumulation of plaque (cholesterol, fats, and other substances) within the coronary arteries, which restricts blood flow to the heart muscle.

B. "Only people with a family history of heart disease are at risk for CAD." Although a family history can increase risk, many other factors, like high blood pressure, smoking, high cholesterol, and lifestyle, contribute to CAD risk.

C. "CAD can be completely cured with a healthy diet and exercise." While lifestyle changes can significantly reduce the progression of CAD and improve symptoms, they do not cure the disease.

D. "I should avoid all physical activity to prevent worsening my CAD." Physical activity, when performed safely and under medical guidance, is beneficial for CAD management and can help improve cardiovascular health.

Correct Answer is ["B","C","D"]

Explanation

A. Obese extremities. Clients with Cushing's syndrome typically experience central (truncal) obesity with thin extremities due to fat redistribution and muscle wasting, not obese extremities.

B. Buffalo hump: A "buffalo hump" (fat pad on the back of the neck) is a common characteristic of Cushing's syndrome due to abnormal fat distribution.

C. Purple striations. Purple or reddish striae on the abdomen and other areas are commonly seen in Cushing's syndrome due to skin thinning and collagen breakdown.

D. Moon face. A round, full face (moon face) is a classic sign of Cushing's syndrome due to fat deposits in the face.

E. Tremors. Tremors are not typically associated with Cushing's syndrome and are more often associated with neurological or metabolic conditions.

A. Hypovolemia leading to decreased renal perfusion B. Acute tubular necrosis C. Urinary tract obstruction D. Chronic kidney disease

Correct Answer is A

Explanation

A. Hypovolemia leading to decreased renal perfusion. Hypovolemia from dehydration and low blood pressure reduces blood flow to the kidneys, resulting in pre-renal AKI, characterized by elevated BUN and creatinine.

B. Acute tubular necrosis. Acute tubular necrosis may cause AKI but is often due to prolonged hypoperfusion, nephrotoxic drugs, or ischemia, not the immediate presentation seen here.

C. Urinary tract obstruction. A urinary tract obstruction leads to post-renal AKI, often with symptoms like flank pain or difficulty urinating, not dehydration and low blood pressure.

D. Chronic kidney disease. Chronic kidney disease is a long-term condition and would not cause the acute symptoms or sudden onset of AKI as seen in this patient.
