Document Summary

Bronchioles (cid:224) terminal bronchioles: responsible for, air conduction bringing air from point of entry to the lungs, air filtration, air humidification, air warming, speech body learns to use changes in air pressure to produce sound, sense of smell. Conchae ridges in the nose that protrude into the nasal cavity to increase sa for warming, and create turbulence so the air travels slower through the nose, maximizing warming. Oropharynx entry point for air entering from the mouth. Epiglottis flap of cartilage that can close the trachea so that food doesn"t enter the windpipe. Shaped like wine glasses; mucus stored in apical region of cells: bear short blunt microvilli, make synaptic contact with afferent nerve endings, considered receptor cells, enteroendocrine cells, basal cells, contain small secretory granules and secrete various peptide hormones, do not extend to the surface, sit on basement membrane. Can see basal bodies of the cilia, look like centrioles. Pseudostratified; made of olfactory receptor cells, basal cells, supporting cells.

Discussion: Assessing the Ears, Nose, and Throat Most ear, nose, and throat conditions that arise in non-critical care settings are minor in nature. However, subtle symptoms can sometimes escalate into life-threatening conditions that require prompt assessment and treatment. Nurses conducting assessments of the ears, nose, and throat must be able to identify the small differences between life-threatening conditions and benign ones. For instance, if a patient with a sore throat and a runny nose also has inflamed lymph nodes, the inflammation is probably due to the pathogen causing the sore throat rather than a case of throat cancer. With this knowledge and a sufficient patient health history, a nurse would not need to escalate the assessment to a biopsy or an MRI of the lymph nodes, but would probably perform a simple strep test. In this Discussion, you consider case studies of abnormal findings from patients in a clinical setting. You determine what history should be collected from the patients, what physical exams and diagnostic tests should be conducted, and formulate a differential diagnosis with several possible conditions. Note: By Day 1 of this week, your instructor will have assigned you to one of the following case studies to review for this Discussion. Also, your Discussion post should be in the SOAP Note format, rather than the traditional narrative style Discussion posting format. Refer to Chapter 2 of the Sullivan text and the Comprehensive SOAP Template in the Week 4 Learning Resources for guidance. Remember that not all comprehensive SOAP data are included in every patient case. Case 1: Nose Focused Examination Richard is a 50-year-old male with nasal congestion, sneezing, rhinorrhea, and postnasal drainage. Richard has struggled with an itchy nose, eyes, palate, and ears for 5 days. As you check his ears and throat for redness and inflammation, you notice him touch his fingers to the bridge of his nose to press and rub there. He says he's taken Mucinex OTC the past two nights to help him breathe while he sleeps. When you ask if the Mucinex has helped at all, he sneers slightly and gestures that the improvement is only minimal. Richard is alert and oriented. He has pale, boggy nasal mucosa with clear thin secretions and enlarged nasal turbinates, which obstruct airway flow but his lungs are clear. His tonsils are not enlarged but his throat is mildly erythematous. To prepare: Review this week's Learning Resources and consider the insights they provide. Consider what history would be necessary to collect from the patient. Consider what physical exams and diagnostic tests would be appropriate to gather more information about the patient's condition. How would the results be used to make a diagnosis? Identify at least 10 possible conditions that may be considered in a differential diagnosis for the patient. Note: Before you submit your initial post, replace the subject line (âWeek 5 Discussionâ) with âReview of Case Study ___,â identifying the number of the case study you were assigned. Post a description of the health history you would need to collect from the patient in the case study to which you were assigned. Explain what physical exams and diagnostic tests would be appropriate and how the results would be used to make a diagnosis. List five different possible conditions for the patient's differential diagnosis and justify why you selected each.

EK MCAT Bio 2, pg 109 says: "Mucus...moistens the air. Ciliamove mucus and dust back toward the pharynx to be removed byspitting or swallowing. In this way, the nasal cavity participatesin the immune function of the respiratory system, preventing somepotentially harmful substances from entering the body."

1. How does mucus moisten the air, exactly?

2. If the cilia move dust particles and harmful substances to beswallowed, how is that considered part of the immune function whenit ends up entering the body anyway?

Thank you!
