The answer is the second one (b): obtain images in a projection 90 degrees to the original scan plane.

Explanation for each option: a. Evaluate the compressibility of the mass with probe pressure: While this can provide additional information about the nature of the mass (e.g., distinguishing between cystic and solid masses), it is not the next immediate step after measuring the long axis. b. Obtain images in a projection 90 degrees to the original scan plane: This is correct because obtaining orthogonal images helps in accurately assessing the size, shape, and extent of the mass, which is crucial for a thorough evaluation. c. Obtain resistive and pulsatility indices from arteries within the mass: This is more relevant for vascular studies and not typically the next step in evaluating a solid breast mass. d. Nothing, the study is complete: This is incorrect because further imaging in different planes is necessary for a comprehensive assessment. e. Evaluate the mass with both a low- and high-frequency transducer: While using different frequency transducers can provide additional detail, it is not the immediate next step after measuring the long axis.

Summary: After measuring the long axis of a solid breast mass, the next step is to obtain images in a projection 90 degrees to the original scan plane to ensure a thorough evaluation of the mass.
