Questions and Answers on Respiratory System Questions
Question 1 of 5
Which of the body systems listed below cooperate to supply O2 to cells and eliminate CO2? 1) digestive system 2) cardiovascular system 3) urinary system 4) respiratory system 5) endocrine system
Correct Answer: B
Rationale: The correct answer is B (2, 4) - cardiovascular system and respiratory system. The cardiovascular system transports O2 from the lungs to the cells and carries CO2 away for elimination by the respiratory system. The respiratory system is responsible for gas exchange, bringing O2 into the body and removing CO2. The other choices are incorrect because: A (3, 5) - The urinary system (3) filters waste from the blood and maintains fluid balance, while the endocrine system (5) regulates hormones and metabolism; neither directly supply O2 or eliminate CO2. C (1, 2) - The digestive system (1) processes food and absorbs nutrients, not involved in gas exchange; the cardiovascular system (2) does cooperate but alone is not sufficient. D (1, 2, 2004) - Choice 2004 is incorrect as it is not a valid option.
Question 2 of 5
Tuberculosis in man is caused by
Correct Answer: A
Rationale: The correct answer is A: A type of bacteria. Tuberculosis is caused by Mycobacterium tuberculosis, a type of bacteria. This bacterium infects the lungs and can spread to other parts of the body. The other choices (B: A virus, C: A protozoan, D: Malnutrition) are incorrect because tuberculosis is specifically caused by a bacterial infection, not a virus, protozoan, or malnutrition. Bacteria can be identified through specific staining techniques and culture methods, distinguishing them from viruses and protozoa. Malnutrition is a risk factor for developing tuberculosis but is not the direct cause of the disease.
Question 3 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 4 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 5 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.
