Questions About the Respiratory System With Answers Questions
Question 1 of 5
The nurse is reviewing the laboratory test results for a client who has recently been diagnosed with hypertension. Which result is most important to communicate to the health care provider?
Correct Answer: D
Rationale: The correct answer is D: Serum creatinine of 2.8 mg/dL. Elevated serum creatinine levels indicate impaired kidney function, which is a common complication of hypertension. Communicating this result to the healthcare provider is crucial as it may indicate renal damage and the need for further evaluation and intervention. A: Serum potassium of 4.5 mEq/L is within the normal range and not directly related to hypertension. B: Serum hemoglobin of 14.7 g/dL is also within the normal range and not a priority in this scenario. C: Blood urea nitrogen of 5 is within the normal range and not as concerning as an elevated creatinine level in the context of hypertension. In summary, the elevated serum creatinine level is most important to communicate as it suggests potential renal damage, which is a serious complication of hypertension.
Question 2 of 5
All of these statements about surfactant are true except
Correct Answer: C
Rationale: Rationale: C is incorrect because according to Laplace's law, smaller alveoli have higher surface tension than larger alveoli. A is correct as surfactants stabilize alveoli. B is true as surfactants reduce surface tension. D is also true as surfactants help prevent fluid leakage. So, C is the exception.
Question 3 of 5
The organ of the respiratory system where air is warmed moistened and cleaned is the:
Correct Answer: D
Rationale: The correct answer is D, "All of the above." The nose warms, moistens, and filters air, the pharynx continues this process, and the larynx further filters and humidifies air. Choosing option D is correct because all three structures work together to prepare air for the lungs. Option A, the nose, is correct but does not cover the entire process. Options B and C, the pharynx and larynx, are also involved in the warming, moistening, and cleaning of air, but individually they do not perform all these functions.
Question 4 of 5
Nurse Reynolds caring for a client with a chest tube turns the client to the side, and the chest tube accidentally disconnects. The initial nursing action is to:
Correct Answer: B
Rationale: The correct initial nursing action is to place the tube in a bottle of sterile water (Choice B) because it prevents air from entering the pleural space, reducing the risk of a tension pneumothorax. Placing the tube in sterile water maintains the water seal, allowing for proper lung expansion. Calling the physician (Choice A) can cause a delay in addressing the issue. Immediately replacing the chest tube system (Choice C) without maintaining the water seal can lead to complications. Placing a sterile dressing (Choice D) may not prevent air leakage effectively.
Question 5 of 5
Nurse Oliver observes constant bubbling in the water-seal chamber of a closed chest drainage system. What should the nurse conclude?
Correct Answer: C
Rationale: The nurse should conclude that the closed chest drainage system has an air leak. Constant bubbling in the water-seal chamber indicates air is escaping from the system, which can lead to a loss of negative pressure needed for proper chest drainage. This could result in inadequate lung re-expansion and increased risk of pneumothorax. A: Incorrect, constant bubbling is not normal. B: Incorrect, pneumothorax would not cause constant bubbling. D: Incorrect, chest tube obstruction would not cause bubbling in the water-seal chamber.
