ADN 202 Respiratory Exam 1 Hoffman Chapter Questions with 100% Verified Correct Answers The nurse includes which nursing diagnosis in the plan of care for the patient admitted with pneumonia? A. Anxiety related to hypoxia B. Deficient knowledge related to cause of disorder C. Fear related to the threat of pain D. Ineffective breathing pattern related to decreased surfactant - Correct Answer Answer: A Rationale: Patients experiencing hypoxia usually have signs of irritability, restlessness, anxiety and confusion. As the brain cells receive less oxygen the patient becomes more confused. The nurse is reviewing orders on the patient who is to receive supplemental oxygen. It is a priority for the nurse to follow up with the provider about which order? A. Nasal cannula at 2 L/min B. Venturi mask at 24% concentration C. Nasal cannula at 8 L/min D. Venturi mask at 50% concentration - Correct Answer Answer: C Rationale: Nasal cannula oxygen should not be ordered at a level greater than 6L/NC. Rates greater than 6L/NC do not increase oxygenation due to the anatomic dead space is full. Greater levels of oxygen causes irritation to mucous membranes. What is the most important information for the nurse to include in the teaching plan about management of home oxygen therapy? (Select all that apply.) A. Do not change the settings of the oxygen without the health-care provider's permission. B. Place "No smoking" signs within the home. C. Oxygen is a fire hazard. D. Others may smoke around you as long as you do not smoke. E. Keep a fire extinguisher near the oxygen source - Correct Answer Answer: A, B, C, and E Rationale: Changing oxygen levels without the permission of the health-care provider could lead to oxygen toxicity. No smoking signs will indicate that oxygen is in the home. Oxygen is a fire hazard. A fire extinguisher is required due to the severity complications if there is a fire related to the oxygen delivery system. The nurse is caring for a patient who is receiving oxygen therapy via the Venturi mask. Which complications are associated with oxygen therapy? (Select all that apply.) A. Oxygen toxicity B. Cachexia C. Bradycardia D. Absorption atelectasis E. Increased dead space - Correct Answer Answer: A and D Rationale: High levels of oxygen can damage the lungs. The high levels of oxygen can cause damage to the alveolar-capillary membrane and inactivate surfactant production in the lungs. Absorption Atelectasis occurs when high levels of oxygen are administered and cause alveoli collapse. The high levels of oxygen dilute the nitrogen that normally prevents alveoli from collapsing, and replaces nitrogen with oxygen in the alveoli.
