What should be the focus when conducting a physical examination of Tina's abdomen?

The focus during a physical examination of Tina's abdomen should be on identifying tenderness, liver size, and any masses. This area of examination is crucial because it helps to assess the overall health of the gastrointestinal system and identify potential issues such as organ enlargement, localized pain, or abnormal growths.

Tenderness can indicate underlying conditions such as inflammation or infection, while measuring liver size is essential in evaluating the health of the liver and diagnosing conditions like hepatomegaly. Checking for masses can help detect tumors or cysts, which might require further investigation.

The other options, while they pertain to general health assessments, do not specifically target the abdominal examination. Measuring height and weight can provide insights into overall health but does not directly relate to the assessment of abdominal issues. Calculating body mass index gives an overview of body composition but is not a focused abdominal examination. Checking blood pressure is crucial for cardiovascular health but also does not pertain to the physical examination of the abdomen itself.
