A patient has been diagnosed with strep throat. The nurse is aware that without treatment, which complication may occur?

A. Ethmoid: The ethmoid sinuses are located between the eyes and are not typically accessible for palpation during a physical examination. Instead, tenderness in this area is assessed through inspection and indirect methods rather than direct palpation.

B. Maxillary: The maxillary sinuses are located in the cheeks and are accessible for palpation. The nurse can assess for tenderness or swelling in this area, which can indicate sinusitis or infection. Palpating the maxillary sinuses is a standard part of the examination for patients with cold and sinus pain.

C. Mastoid: The mastoid process is located behind the ear and contains air cells, but it is not directly involved in sinus pain associated with cold symptoms. While mastoid tenderness may indicate a different type of infection (such as mastoiditis), it is not part of the sinus assessment.

D. Sphenoid: The sphenoid sinuses are located deep within the skull, behind the nasal cavity, and are not accessible for palpation during a physical examination. Any issues with the sphenoid sinuses would typically be assessed through imaging studies rather than physical palpation.

A. XI; have patient shrug their shoulders against resistance: Cranial nerve XI, also known as the accessory nerve, is responsible for the innervation of the sternocleidomastoid and trapezius muscles. Damage to this nerve can lead to weakness in shoulder shrugging and difficulty turning the head. Asking the patient to shrug their shoulders against resistance allows the nurse to assess the function of this nerve effectively.

B. XI; palpate the anterior and posterior triangles: While palpating the anterior and posterior triangles of the neck can provide useful anatomical information, it does not specifically assess the function of cranial nerve XI. This action may not directly address the patient's complaints or evaluate nerve function adequately.

C. XII; assess for a positive Romberg sign: Cranial nerve XII, the hypoglossal nerve, is responsible for tongue movement. The Romberg test assesses balance and proprioception, not directly related to neck and shoulder pain or head movement. This option is not appropriate in this context.

D. XII; percuss the sternomastoid and submandibular neck muscles: Percussion is not a standard method for assessing cranial nerve function and would not provide useful information about nerve damage. This option also incorrectly identifies the relevant cranial nerve, as cranial nerve XII is not involved in neck and shoulder movement.
