Questions About the Respiratory System With Answers Questions
Question 1 of 5
Adams apple formation because of
Correct Answer: D
Rationale: The correct answer is D because the formation of the Adam's apple is influenced by the production of sex hormones, which increases during puberty, leading to growth in the laryngeal prominence. This growth is more prominent in males due to higher levels of testosterone. Therefore, all the factors mentioned in choices A, B, and C contribute to the formation of the Adam's apple.
Question 2 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 3 of 5
Which sign would indicate possible heart failure in a client with heart disease in the immediate postoperative period?
Correct Answer: A
Rationale: The correct answer is A: Tachypnea. In the immediate postoperative period, tachypnea in a client with heart disease could indicate possible heart failure. Tachypnea is a common sign of heart failure as the heart struggles to pump effectively, leading to increased respiratory rate to compensate. Bradycardia (B) is a slow heart rate, which is not typically associated with heart failure. Hypotension (C) is low blood pressure, which can be a sign of shock but not specific to heart failure. Increased wound bleeding (D) may indicate issues with clotting or surgical complications, but it is not directly related to heart failure.
Question 4 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 5 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.
