Questions About the Respiratory System Questions
Question 1 of 5
A nurse is assessing a client who is recovering from a lung biopsy. Which assessment finding requires immediate action?
Correct Answer: B
Rationale: The correct answer is B: Absent breath sounds. This finding could indicate a pneumothorax, a serious complication post lung biopsy requiring immediate intervention. Absent breath sounds suggest air accumulation in the pleural space, causing lung collapse. Prompt action is crucial to prevent respiratory distress. Increased temperature (A) may indicate infection but not as urgent as addressing a pneumothorax. Productive cough (C) is common post-procedure. Incisional discomfort (D) is expected and can be managed with appropriate pain relief measures.
Question 2 of 5
The common drugs used against TB is
Correct Answer: D
Rationale: The correct answer is D, "All these." PAS, Ethambutol, and Streptomycin are all common drugs used against TB. PAS inhibits bacterial folic acid synthesis, Ethambutol inhibits cell wall synthesis, and Streptomycin inhibits protein synthesis. Using a combination of these drugs helps to target different aspects of TB bacteria, reducing the likelihood of resistance development. Therefore, all of these drugs are essential in the treatment of TB, making choice D the correct answer.
Question 3 of 5
The nurse is assessing a patient who frequently coughs after eating or drinking. How should the nurse best follow up this assessment finding?
Correct Answer: B
Rationale: The correct answer is B: Perform a swallowing assessment. This is the best follow-up because coughing after eating or drinking can be a sign of dysphagia, a swallowing disorder. By performing a swallowing assessment, the nurse can identify any issues with the patient's ability to swallow safely, which can lead to aspiration and respiratory complications. Obtaining a sputum sample (A) may not provide relevant information in this context. Inspecting the patient's tongue and mouth (C) may not directly address the coughing after eating. Assessing the patient's nutritional status (D) is important but may not address the immediate issue of coughing after eating or drinking.
Question 4 of 5
The nurse is performing a respiratory assessment of a patient who has been experiencing episodes of hypoxia. The nurse is aware that this is ultimately attributable to impaired gas exchange. On what factor does adequate gas exchange primarily depend?
Correct Answer: B
Rationale: The correct answer is B: An adequate ventilation-perfusion ratio. Adequate gas exchange primarily depends on the matching of ventilation (air reaching the alveoli) and perfusion (blood flow to the alveoli). A mismatch in this ratio can lead to impaired gas exchange, resulting in hypoxia. Option A relates to gas movement efficiency but does not address the matching of ventilation and perfusion. Option C mentions shunted blood, which is not directly related to the ventilation-perfusion ratio. Option D is unrelated to gas exchange. In summary, the ventilation-perfusion ratio is crucial for optimal gas exchange, making it the correct choice.
Question 5 of 5
The nasal conchae epithelial surface serves to:
Correct Answer: D
Rationale: Rationale: The nasal conchae increase surface area, causing air turbulence to warm, moisten, and filter inhaled air. This helps in preventing respiratory issues. Choice A is correct as it explains the primary function of the conchae. Choice B is incorrect as the primary function is not filtering. Choice C is incorrect as the conchae primarily warm and moisten inhaled air rather than recapture moisture from exhaled air. Overall, choice D is correct as it encompasses all the functions of the nasal conchae.
