Questions and Answers on Respiratory System Questions
Question 1 of 5
Expiration involves
Correct Answer: A
Rationale: The correct answer is A because expiration involves the relaxation of the diaphragm and intercostal muscles. During expiration, the diaphragm moves up and the intercostal muscles relax, causing the thoracic cavity to decrease in volume. This increase in pressure forces air out of the lungs. Choice B is incorrect as it describes the process of inspiration, not expiration. Choice C is incorrect because expiration involves both the diaphragm and intercostal muscles, not just the diaphragm muscles. Choice D is incorrect as the intercostal muscles also relax during expiration, rather than contracting.
Question 2 of 5
A nurse caring for a client removes the client's oxygen as prescribed. The client is now breathing what percentage of oxygen in the room air?
Correct Answer: B
Rationale: The correct answer is B (21%). Room air contains approximately 21% oxygen. By removing the supplemental oxygen, the client is now breathing the oxygen content present in the surrounding air. Choices A, C, and D are incorrect as they do not reflect the standard oxygen concentration in room air. Oxygen concentration in room air is typically around 21%, making choice B the most accurate option.
Question 3 of 5
While assessing a client who has facial trauma the nurse auscultates stridor. The client is anxious and restless. What action would the nurse take first?
Correct Answer: A
Rationale: Rationale: Stridor indicates upper airway obstruction, which can quickly progress to respiratory distress. As the client is anxious and restless, immediate intervention is crucial. Contacting the primary health care provider and preparing for intubation is the priority to secure the airway and ensure adequate oxygenation. Administering albuterol, positioning in high-Fowler, or deep-breathing exercises are not appropriate as they do not address the acute airway compromise.
Question 4 of 5
A hospital nurse is participating in a drill during which many "clients" with inhalation anthrax are being admitted. The nurse would anticipate administering the following EXCEPT?
Correct Answer: D
Rationale: The correct answer is D: Ethambutol. Ethambutol is not used in the treatment of inhalation anthrax. The treatment of choice for inhalation anthrax is a combination of antibiotics such as ciprofloxacin, doxycycline, and sometimes vancomycin. Ethambutol is primarily used in the treatment of tuberculosis, not anthrax. It is important for the nurse to be knowledgeable about the appropriate medications for specific conditions to provide effective care.
Question 5 of 5
Which of the following would be the most appropriate nursing intervention when caring for a client with a fractured rib?
Correct Answer: A
Rationale: The correct answer is A. Applying an immobilization device after physician evaluation helps stabilize the rib and reduce pain. B (discouraging deep breaths) is harmful as it can lead to atelectasis. C (advising against analgesics) is incorrect because pain management is essential. D (increasing fluid intake) is secondary and depends on the presence of pulmonary complications.
