I  Republic of the Philippines Bulacan State University City of Malolos Care of Clients with Problems in Oxygenation, Fluid, Electrolyte and Acid – Base Balance, Infectious, Inflammatory and Immunologic and Cellular Aberrations (Acute and Chronic) (NCM 112 – A/Lecture Course) Unit 1 Title Nursing Care of At Risk and Sick Adult Clients with Alterations/ Problems in Oxygenation (The Upper Respiratory System and its Disorders) Prepared by John Paul E. Mendoza, M.A.N., R.N. Course Instructor A.Y. 2024-2025- 1st Semester Page | 1 Introduction BulSU CON’s NCM 112-A gives additional venue for nursing students to continue developing their knowledge, skills, values and attitudes from their previously finished courses. It further highlights learning outcomes they incurred from courses such as NCM 100 (Theoretical Foundations of Nursing), NCM 101 (Health Assessment), NCM 102 (Health Education), NCM 103 (Fundamentals of Nursing Practice) and NCM 106 (Pharmacology) respectively. This course accounts to 8 units (or 8 hours per week) of the total third level unit requirements during the first semester of the academic year. As the first unit title implies, this course begins with a short review of your respiratory system and ends with medical – surgical managements for every common respiratory disease worldwide. It will cover the upper respiratory system initially succeeding with three other units discussing oxygenation-related concepts as well. Aside from textbooks – derived oxygenation concepts that can be achieved from this module, there will be some exercises or tasks to accomplish which are designed and intended for the aforementioned intent of this course. The evolution of educational system through the outcome-based education (OBE) is reflected from these self- directed activities which not only help the teachers but nursing students themselves monitor their progress in the profession. This particular module is divided into 4 lessons: Lesson 1 Overview of the Respiratory System Lesson 2 Assessment of the Respiratory Functions Lesson 3 Common Respiratory Interventions Lesson 4 Management of the Patients with Upper Respiratory Tract Disorders Objectives/Competencies Upon completion of this module, you are expected to: 1. Examine the extent of your knowledge in respiratory system 2. Apply previously incurred basics of health history-taking and physical examination to respiratory disorders 3. Gather and infer information regarding common respiratory interventions 4. Analyze pathophysiologic responses to oxygenation alterations 5. Formulate a plan of care to address the respiration- related health needs Page | 2 Pre-test 1 Multiple Choice. Shade the letter of your answer in the numbered boxes. Note: It is recommended that a No. 2 pencil be used as it practices consistent and careful test-taking in the future Nursing Licensure Examination (NLE). 1. Which of the following is NOT one of the four main events of respiration? a. pulmonary ventilation b. respiratory gas transport c. residual volume d. external respiration 2.

The organs of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, and their smaller branches, and the lungs, which contain the alveoli, or terminal air sacs. (Marieb, 2018) Figure 1.1 Parts of the Respiratory System I. Functional Anatomy of the Upper Respiratory System A. Nose B. Paranasal sinuses They lighten the skull, and they act as resonance chambers for speech Classifications: 1. Frontal 2. Sphenoid 3. Ethmoid 4. Maxillary bones C. Pharynx It serves as a passageway for food and air Subdivided into three portion: nasopharynx, oropharynx and laryngopharynx Page | 5  Auditory tubes, which drain the middle ear, open into the nasopharynx Tonsils – found also in the pharynx; the pharyngeal tonsils (adenoid), palatine tonsils, and lingual tonsils D. Larynx “Voicebox”; routes air and food into the proper channels and plays a role in speech Thyroid cartilage – common called the “adam’s apple” is the largest hyaline cartilage which protrudes anteriorly Epiglottis – “guardian of the airways”; protects superior opening of the larynx Vocal folds or true vocal cords – it vibrates with expelled air which allows us to speak Glottis – slitlike passageway between the vocal folds E. Trachea Also called “windpipe”, has a length of 10-12 cm or about 4in, is lined with a ciliated mucosa. Cilia of the trachea function to propel mucus. Loaded with dust particles and other debris, away from the lungs to the throat, where it can be swallowed or spat out. II. Functional Anatomy of the Lower Respiratory System A. Primary Bronchi The right and left primary bronchi are formed by the division of the trachea The right primary bronchus is wider, shorter and straighter than the left; also more to some lodging of foreign object It warm, cleanse and humidify air that enters the lungs B. Lungs They occupy the entire thoracic cavity except for the most central area – mediastinum Apex – the narrow superior portion of each lung, located just deep to the clavicle Base – broad lung area resting on the diaphragm Each lung is divided into lobes by fissures; the left lung has 2 lobes and the right lung has 3 lobes Pleura – visceral serosa that covers the surface of each lung; it has 2 forms: the parietal pleura and the visceral pleura Bronchioles – subdivisions of the primary bronchi inside the lungs before it terminate in alveoli Alveoli – air sacs; the only site of gas exchange III. Respiratory Physiology A. 4 Distinct Events during Respiration: 1. Pulmonary ventilation 2. External respiration 3. Respiratory gas transport 4. Internal respiration B. Mechanics of Breathing Page | 6  1. Inspiration 2. Expiration 3. Nonrespiratory Air Movements C. Respiratory Volumes and Capacities Tidal volume – the volume of air inhaled and exhaled with normal quiet breathing (500ml) Inspiratory reserve volume – the maximum volume that can be inhaled following a normal quiet inhalation (2100-3200ml) Expiratory reserve volume - the maximum volume that can be exhaled following a normal quiet exhalation (1200ml) Residual volume – the volume of air that remains in the lungs after forceful exhalation Vital capacity – the maximum volume of air that can be exhaled after a maximum inhalation; the sum of the TV, IRV, and ERV (4800ml) Inspiratory Capacity – total amount of air that can be inhaled following normal quiet exhalation; the sum of TV and IRV (3,600ml) Total Lung Capacity – the total volume of the lungs at maximum inflation; sum of TV, IRV, ERV and RV (6,000ml) D. Respiratory Sounds 1. Bronchial sounds 2. Vesicular breathing sounds E. Factors Influencing Respiratory Rate and Depth: 1. Physical factors 2. Volition (Conscious Control) 3. Emotional factors 4. Chemical factors F. Neurologic Control of the Respiratory System 1. Medulla oblongata – center for respiration 2. Pons – control rate and depth of respiration 3. Phrenic Nerve – controls diaphragmatic movement 4. Pneumotaxic center – controls pattern of respiration (E.g. Kussmaul’s) 5. Apneustic center – stimulate medulla o create prolonged and deep respiration This outline or summary of respiratory parts and physiologies were chiefly patterned after the textbook of Marieb’s Anatomy and Physiology particularly the chapter of Respiratory System. This mentioned textbook has been the leading recommended textbook of the college over the years and full discussion of many anatomical terminologies noted can be browsed in there. Though the sequencing of chapter numbers may vary to all textbook editions, the topics or contents for respiratory system would be almost similar hence every nursing student is encouraged to keep a hard copy or e-book of it for future usage and uniformity of their medical knowledge.

Lesson 2 outlines key points to a complete respiratory function assessment as follows:  Risk / Causative Factors  Physical Examination  Diagnostic Procedures / Evaluation This section of the course unit best guide nursing students as they read their Medical – Surgical Nursing textbooks since majority of the information vital to their learning process were simplified here based also on the contents of most common references which this course utilized such as Brunner & Suddarth’s Textbook of Medical-Surgical Nursing and Udan’s Medical-Surgical Nursing: Concepts and Clinical Application. Similarly, nursing students for practical reasons are not encouraged to become very particular with the latest editions they should secure for studying since previous editions may still suffice as agreed throughout the course. Chapters for respiratory system and its disorders among all Medical – Surgical Nursing textbooks will provide full discussion of outlined topics. A. Risk Factors for Respiratory Diseases 1. Smoking (the single most important contributor to lung disease) 2. Exposure to secondhand smoke 3. Personal or family history of lung disease 4. Genetic makeup 5. Allergens and environmental pollutants 6. Recreational and occupational exposure B. Physical Examination 1.

Chest Pain - May be associated with pulmonary or cardiac disease - May be described as sharp, stabbing or intermittent, or it may be dull, aching and persistent - Assess for scale of pain, location and intensity 5. Adventitious Breath Sounds a. Crackles - Soft, high-pitched, popping sounds may indicate fluids in the lungs b. Wheezing - High – pitched; continuous; hoarse; whistling - Indicates obstruction or narrowing common among asthma and COPD patients c. Stridor - Strong gush of air; a turbulent gas flow from the upper respiratory airway - E.g. obstruction of epiglottis, laryngeal tumor Knowledge Bonus 1.1 Hear your Breath Sounds If given an opportunity for online browsing, hearing these different abnormal breath sounds can also level up your interest with the topic. Your course instructor provides you an NCLEX Review link entitled “Lung sounds - Breath sounds Types & Causes” as a bonus. In the link, it clearly differentiates the breath types especially their distinct actual sounds. You may copy the link here - https://www.youtube.com/watch?v=0fEy-EDHP5Q Page | 10 6.
