Which location should the practical nurse (PN) palpate to determine if a client's submandibular lymph nodes are enlarged?

A. The submandibular lymph nodes are located beneath the lower jaw, in the area where the jawbone meets the neck. This is the correct location to palpate for enlargement of these lymph nodes. B. The temporal bone is located on the side of the head, not relevant to the location of the submandibular lymph nodes. Palpation for these nodes occurs beneath the lower jaw, not near the temporal bone. C. Lateral to the trachea refers to the location of other lymph nodes such as the anterior cervical or supraclavicular nodes, not the submandibular nodes. Submandibular nodes are specifically beneath the jaw. D. Above the upper jaw does not correspond to the location of the submandibular lymph nodes. These nodes are palpated beneath the lower jaw, making this option incorrect.
