The diagnosis of Cushing syndrome is often based on:

Obesity

A 24-hour urine collection

Chronic renal failure

Alcoholism

Answer and Explanation

The Correct Answer is B

A. Obesity is a common symptom of Cushing syndrome but is not the primary diagnostic criterion. Other tests are needed to confirm the diagnosis.

B. A 24-hour urine collection for cortisol is one of the most common and reliable methods for diagnosing Cushing syndrome. Elevated cortisol levels in the urine are indicative of the syndrome.

C. Chronic renal failure is not related to the diagnosis of Cushing syndrome. While Cushing syndrome may affect renal function, it is not the primary diagnostic tool.

D. Alcoholism can cause symptoms similar to those of Cushing syndrome, but it is not used as a diagnostic criterion. The diagnosis of Cushing syndrome requires specific tests, such as urine cortisol measurement.

Correct Answer is A

Explanation

A. Chronic alveolar distention, often seen in conditions like emphysema, leads to the enlargement of the alveoli and results in a barrel-shaped chest. This is due to the loss of elasticity in the lungs, causing air trapping and an increased anterior-posterior diameter of the chest.

B. Chronic costochondritis causes inflammation of the cartilage between the ribs and sternum, leading to localized pain but not a barrel chest.

C. Smoking is a major risk factor for the development of chronic obstructive pulmonary disease (COPD), which can lead to chronic alveolar distention and a barrel chest, but smoking alone is not the direct cause of the chest shape.

D. Hypokalemia affects muscle function, including the muscles involved in respiration, but it does not directly cause a barrel chest.

A. pH 7.50, HCO3- 20 mEq/L. PaCO2 32 mm Hg B. pH 7.25, HCO3- 19 mEq/L, PaCO 30 mm Hg C. pH 7.55, HCO3- 30 mEq/L. PaCO 31 mm Hg D. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg

Correct Answer is D

Explanation

A. A pH of 7.50 is alkalotic, and the bicarbonate level is low, which is inconsistent with chronic kidney disease, where metabolic acidosis is more common.

B. The pH of 7.25 indicates acidosis, but the bicarbonate level is too low, and the PaCO2 is too low to be consistent with a typical acid-base imbalance in chronic kidney disease.

C. The pH of 7.55 is alkalotic, which does not fit the typical presentation of chronic kidney disease, which is associated with metabolic acidosis.

D. A pH of 7.30 indicates mild acidosis, and the bicarbonate level is within a normal range for compensatory mechanisms. The elevated PaCO2 of 50 mm Hg indicates respiratory compensation for metabolic acidosis, which is expected in chronic kidney disease, where the kidneys are unable to adequately excrete acid.
