Exam Questions on Respiratory System Questions
Question 1 of 5
For which client(s) would you assign the nursing care to the new RN under your supervision? (Choose all that apply.)
Correct Answer: D
Rationale: The correct answer includes A and D. Assigning care for clients with moderate persistent asthma (A) and a new diagnosis of esophageal cancer (D) is appropriate for a new RN under supervision. Clients requiring tracheostomy care (B) or post-lobectomy recovery (C) involve complex care unsuitable for a new RN.
Question 2 of 5
What is a primary treatment goal for cor pulmonale?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A nurse is caring for a client who received benzocaine spray prior to a recent bronchoscopy. The client presents with continuous cyanosis even with oxygen therapy. Which action should the nurse take next?
Correct Answer: B
Rationale: The correct answer is B: Notify the Rapid Response Team. Continuous cyanosis despite oxygen therapy following benzocaine administration may indicate methemoglobinemia, a serious adverse effect. Rapid Response Team should be alerted for immediate intervention and monitoring. Albuterol treatment (A) would not address methemoglobinemia. Assessing peripheral pulses (C) may not provide immediate assistance. Obtaining blood and sputum cultures (D) is not the priority in this situation.
Question 4 of 5
Hemoglobin affinity for Oxygen is to the P50 (O2 tension that produces 50% saturation of Hb)
Correct Answer: B
Rationale: The correct answer is B. Hemoglobin affinity for oxygen is inversely related to P50. When P50 is lower, hemoglobin has higher affinity for oxygen, meaning it binds oxygen more readily at lower oxygen tensions. Conversely, when P50 is higher, hemoglobin has lower affinity for oxygen. This relationship is crucial for the efficient loading and unloading of oxygen in tissues. Choices A, C, and D are incorrect because hemoglobin affinity for oxygen is not directly related, unrelated, or simply related to P50.
Question 5 of 5
Which of the following gas mixture is used by Divers to prevent Oxygen toxicity
Correct Answer: B
Rationale: The correct answer is B: Oxygen and Nitrogen. This gas mixture is used by divers to prevent Oxygen toxicity because it closely mimics the composition of the air we breathe. Oxygen toxicity can occur at high partial pressures of Oxygen, which can lead to seizures and other serious health issues. Choices A, C, and D are incorrect because CO2 and rare gases are not typically used in diving gas mixtures, and including CO2 in the mixture can increase the risk of Oxygen toxicity. Nitrogen is used as a diluent to reduce the partial pressure of Oxygen, making it safer for divers.
