Which of the following tasks is allowed for a licensed chiropractor?

The ability for a licensed chiropractor to adjust spinal alignments is a fundamental part of chiropractic care and falls within the scope of practice defined by state laws. Chiropractors are specifically trained to assess and treat musculoskeletal conditions, primarily through spinal manipulation and adjustments. This hands-on approach is rooted in the philosophy of chiropractic, which emphasizes the relationship between the spine and the nervous system, aiming to restore health through physical adjustments.

In contrast, performing surgeries usually requires a different level of medical training and licensure, which chiropractors do not possess. Similarly, prescribing medication is generally reserved for those with medical or pharmaceutical training, as it is regulated and governed by specific medical licensing standards. Lastly, practicing acupuncture typically requires certification in that specific modality, as it involves specialized training that goes beyond the standard chiropractic curriculum. Thus, adjusting spinal alignments is the only task listed that is clearly within the legal and professional boundaries of a licensed chiropractor's practice.
