Respiratory Nursing: Test Questions and Answers, Exams of Nursing

Aims Community CollegeNursing

A comprehensive set of test questions and answers related to respiratory physiology and nursing interventions. It covers key concepts such as perfusion, oxygen consumption, breathing techniques, lung sounds, and oxygen delivery devices. The material is designed to help students understand the clinical aspects of respiratory care, including the management of hypoxemia and hypoxia, airway maintenance, and the interpretation of diagnostic parameters. It also addresses the nursing considerations for patients requiring respiratory support, such as cpap or bipap therapy, and the importance of oral care to prevent respiratory distress. Useful for nursing students and healthcare professionals seeking to review and reinforce their knowledge of respiratory care. (418 characters)

  3. What does rhonchi indicate? -- Answer โœ”โœ” Secretions in airway
  4. What does rhonchi sound like? -- Answer โœ”โœ” snoring, lower pitched
  5. What does wheezing indicate? -- Answer โœ”โœ” narrowing of the airways due to spasm or obstruction
  6. What does wheezing sound like? -- Answer โœ”โœ” musical, whistling sound
  7. What does a pleural friction rub indicate? -- Answer โœ”โœ” inflammation of the pleural space
  8. What does a pleural friction rub sound like? -- Answer โœ”โœ” Grating sound
  9. What does stridor indicate? -- Answer โœ”โœ” Airway obstruction
  10. What does stridor sound like? -- Answer โœ”โœ” High-pitched, inspiratory crowing sound
  1. A non-rebreather can use up to - liters per minute. -- Answer โœ”โœ” 10 - 15 (80- 95% FiO2)
  2. With heated high flow (Vapotherm), you must always ensure the oxygen is ____. -- Answer โœ”โœ” Humidified
  3. What is an oropharyngeal airway (OPA)? -- Answer โœ”โœ” a curved device inserted through the patient's mouth into the pharynx to help maintain an open airway (holds tongue out of the way)
  4. How to insert an oropharyngeal airway (OPA)? -- Answer โœ”โœ” Measure from corner of lip to tip of ear, lube, insert sideways and then flip it once in
  5. What are the indications for an oropharyngeal airway (OPA)? -- Answer โœ”โœ” Unconscious or semi-conscious pt, seizures, prevent biting on ET tube
  6. What are the complications of an oropharyngeal airway (OPA)? -- Answer โœ”โœ” Gagging unconscious pt, vomiting and aspiration
  7. What is a nasopharyngeal airway (NPA)? -- Answer โœ”โœ” a flexible breathing tube inserted through the patient's nostril into the pharynx to help maintain an open airway
  8. What is the indication for a nasopharyngeal airway (NPA)? -- Answer โœ”โœ” Better for conscious patients, used to facilitate frequent suctioning
  1. What are the complications of a nasopharyngeal airway? -- Answer โœ”โœ” Nosebleeds, sinusitis, ulcerations
  2. What must you monitor for when a patient has an OPA or NPA? -- Answer โœ”โœ” Skin breakdown, infection
  3. What are the indications for BIPAP or CPAP? -- Answer โœ”โœ” Patients struggling to ventilate but do not need invasive mechanical ventilation
  4. Nursing considerations for CPAP or BIPAP? -- Answer โœ”โœ” Monitor skin, ORAL CARE, pt may have anxiety and require coaching, pain management, sleep management,
  5. How to prevent skin breakdown with BIPAP or CPAP? -- Answer โœ”โœ” Place barrier (like duoderm or tegaderm) around the edges
  6. What type of food should a patient on CPAP or BIPAP eat? -- Answer โœ”โœ” High protein, high calorie, easy to chew/drink, small portions
  7. Lack of oral care can lead to... -- Answer โœ”โœ” Mucous build up which can cause respiratory distress
  8. What is ventilation? -- Answer โœ”โœ” movement of air in and out of the lungs
  9. How does the chest shape change with aging? -- Answer โœ”โœ” The anterior-posterior diameter of the chest increases
  1. What is the oxygen-hemoglobin dissociation curve? -- Answer โœ”โœ” Graph that shows the relationship between the amount of oxygen bound to hemoglobin and the partial pressure of oxygen in the blood
  2. What is partial pressure of oxygen? -- Answer โœ”โœ” Concentration of oxygen. It is called partial pressure because it is a measure of the pressure exerted by just one specific gas within a mixture of multiple gases.
  3. What does a shift to the LEFT mean on the oxygen-hemoglobin dissociation curve? -
  • Answer โœ”โœ” Hemoglobin picks up oxygen easier but delivers less to the tissues because the hemoglobin won't release the oxygen.
