Respiratory System Questions and Answers PDF Questions
Question 1 of 5
The atmospheric pressure at sea level is
Correct Answer: B
Rationale: The atmospheric pressure at sea level is typically around 760mm Hg, which is equivalent to 101.3 kilopascals. This is the standard atmospheric pressure used in various scientific calculations. This value represents the pressure exerted by the weight of air above a given area at sea level. Choice B is correct because it accurately reflects the standard atmospheric pressure at sea level. Choices A, C, and D are incorrect as they do not match the accepted value for atmospheric pressure at sea level.
Question 2 of 5
A person met with an accident and died instantly without any injury to heart, brain, stomach and kidney. One of the following is a reason for his death
Correct Answer: D
Rationale: The correct answer is D: Diaphragm got punctured. The diaphragm is a crucial muscle responsible for breathing. If it gets punctured, it can lead to immediate death due to respiratory failure. In this scenario, since there are no injuries to vital organs like the heart, brain, stomach, or kidney, the only plausible reason for instant death would be a punctured diaphragm affecting the person's ability to breathe. A: Intestine getting twisted would not lead to instant death without affecting the heart, brain, stomach, or kidney. B: RBC becoming coagulated would not result in immediate death without directly impacting vital organs. C: Stomach stopping digestion is not a life-threatening condition that would cause instant death without injury to vital organs.
Question 3 of 5
Oxygen and carbon dioxide concentration in the alveolar air is respectively
Correct Answer: D
Rationale: The correct answer is D (13.1% oxygen and 5% carbon dioxide). In the alveolar air, the oxygen concentration is around 13.1%, which is lower than atmospheric air (21%) due to gas exchange in the lungs. The carbon dioxide concentration in alveolar air is around 5%, higher than atmospheric air (0.04%). Choices A, B, and C have oxygen concentrations higher than what is found in alveolar air, making them incorrect. Choice B also has a carbon dioxide concentration higher than what is typically found in alveolar air, making it incorrect.
Question 4 of 5
A nurse assesses a client after an open lung biopsy. Which assessment finding is matched with the correct intervention?
Correct Answer: C
Rationale: The correct answer is C. Reduced breath sounds after an open lung biopsy could indicate a potential complication such as pneumothorax, requiring immediate attention. Calling the primary health care provider allows for timely assessment and intervention. Choice A is incorrect because dizziness alone may not warrant calling the Rapid Response Team without further assessment. Choice B is incorrect as a heart rate of 55 beats/min may not necessarily indicate a need to withhold pain medication without considering other factors. Choice D is incorrect as a respiratory rate of 18 breaths/min does not necessarily mean the oxygen flow rate should be decreased without further assessment.
Question 5 of 5
The nurse assesses the client using the device pictured below to deliver 50% O2: The nurse finds that the mask fits snugly the skin under the mask and straps is intact and the flow rate of the oxygen is 3 L/min. What action by the nurse is best?
Correct Answer: C
Rationale: The correct answer is C: Immediately increase the flow rate. A flow rate of 3 L/min is inadequate to deliver 50% O2 through a mask. Increasing the flow rate will ensure the client receives the prescribed oxygen concentration. Incorrect choices: A: Assess the client's oxygen saturation - This is not the priority as the oxygen delivery is suboptimal. B: Document these findings in the chart - Documentation is important but addressing the oxygen delivery issue is more critical. D: Turn the flow rate down to 2 L/min - This would further reduce the oxygen concentration, which is not appropriate in this case.
