First, are we talking about written report vs radio report vs hand off report?
Talking about the written report, it depends on what's on the overall report. "Vitals WNL" isn't a problem, in my opinion, provided the actual numbers are someplace else in the report and... well... within normal limits. If they are just out, than something along the lines of "pulse is slightly elevated, but not concerning at this time" would work (after all, there's elevated and ELEVATED). Next, I would cover each section individually instead of groups. "Airway patent, lung sounds clear, no rales, wheezes, rhonchi, heart is at a regular rate, no murmurs, rubs, gallops. Abdomen is soft, non-tender, positive bowel sounds times 4."
For example, I'm currently rotating through pain medicine right now. When I dictate my physical exam on a clinic patient, the objective section looks something like this for a patient with a normal exam focusing on the lumbar region (e.g. a patient with spinal foramen stenosis).
O: Vitals ______
General: Well developed, well nourished male, no acute distress.
CV: Regular rate, no murmurs, rubs. gallops.
Resp: Clear to auscultation bilaterally, no wheezes, rales, rhonchi.
Abdomen: Soft, non-tender, positive bowel sounds times 4
Neuro: A/Ox4, muscle strength 5/5 and equal bilaterally in lower extremities, DTR 2/4 and equal bilaterally at S1-S2 [Achilles ligament] and L3-L4 [patellar ligament], sensory is intact to light touch and equal bilaterally in lower extremities, gait is balanced, no pain elicited on extension and flexion of the lumbar, straight leg raise negative bilaterally.
If you have the chance to look at Bates Guide to the Physical Exam, it includes the negative documentation for both a general physical exam and a focused physical exam when they cover each exam.
