For which client would you likely expect to perform diagnostic imaging based on their symptoms?

The client experiencing diffuse abdominal pain is likely to require diagnostic imaging because this symptom can indicate a wide range of potential underlying conditions, some of which may be serious and not immediately discernible through physical examination alone. Conditions such as appendicitis, pancreatitis, bowel obstruction, or perforated viscus could present with diffuse abdominal pain, making imaging a crucial step in identifying the specific cause. Imaging studies, such as an abdominal ultrasound or CT scan, can help visualize the organs and structures within the abdomen to assist in accurate diagnosis and appropriate management.

In contrast, the other clients present with symptoms that typically do not necessitate imaging. The client with a severe earache may benefit more from a physical examination and potential treatment for an infection or other ear-related issues rather than imaging. The client with a poison ivy rash likely requires topical treatments or antihistamines rather than imaging, as the issue is dermatological. Lastly, a client with diplopia can have various causes, including neurological ones, but might first need a neurological examination rather than immediate imaging unless there are alarming signs that warrant it.
