Which review of systems is concerned with symptoms such as frequent sneezing and postnasal drip?

The correct choice is the review of systems that focuses on the Ears, Nose, and Throat (ENT) because symptoms like frequent sneezing and postnasal drip are directly related to conditions affecting the nasal passages and throat. The ENT review specifically encompasses issues related to allergies, sinusitis, and infections that can cause symptoms involving sneezing and drainage from the nasal cavity.

In this context, considering the other options reinforces why the ENT category is the most appropriate. The Respiratory system does deal with breathing-related symptoms but would typically focus on lung function and issues such as cough or shortness of breath rather than nasal symptoms. The Cardiovascular review primarily addresses heart and vascular issues, such as chest pain or irregular heartbeats. Lastly, the Musculoskeletal system pertains to bones, muscles, and joints, focusing on pain or dysfunction in those areas, which does not relate to the symptoms of sneezing or postnasal drip. This clear distinction in focus makes the Ears, Nose, and Throat review the most relevant choice for the described symptoms.
