Multiple Choice Questions About Respiratory System Questions
Question 1 of 5
Which of the following are structural features of the trachea?
Correct Answer: D
Rationale: The correct answer is D because all the choices are structural features of the trachea. A is correct as the trachea has C-shaped cartilage rings for structural support. B is correct as the trachea contains smooth muscle fibers that help regulate airflow. C is correct as the trachea is lined with cilia that help sweep mucus and foreign particles out of the respiratory tract. Therefore, all of the above choices are structural features of the trachea, making D the correct answer.
Question 2 of 5
Pulmonary ventilation also called
Correct Answer: C
Rationale: The correct answer is C: Breathing. Pulmonary ventilation refers to the process of breathing, which involves both inhalation and exhalation. Inhalation is the act of taking in air, while exhalation is the act of expelling air. Therefore, the term "pulmonary ventilation" encompasses both inhalation and exhalation, making choice C the correct answer. Choices A and B are incorrect because they only represent one part of the breathing process. Choice D is incorrect because it suggests that all choices are correct, which is not accurate in this context.
Question 3 of 5
The nurse is assessing a patient with chronic obstructive pulmonary disease (COPD). Which assessment finding indicates a potential complication and requires the nurse's immediate attention?
Correct Answer: A
Rationale: The correct answer is A: Distended neck veins. This finding indicates potential right-sided heart failure, a complication of COPD called cor pulmonale. The nurse should address this immediately to prevent further deterioration. Distended neck veins suggest increased central venous pressure and impaired right heart function. Left lower quadrant tenderness (B) is unrelated to COPD. Urinary output of 40 mL/hr (C) is within normal range. Excessive coughing (D) is a common symptom of COPD but does not indicate an immediate complication.
Question 4 of 5
Which metal ion is often present in the active site of carbonic anhydrase enzymes?
Correct Answer: C
Rationale: The correct answer is C: Zinc (Zn). Zinc is often present in the active site of carbonic anhydrase enzymes because it plays a crucial role in catalyzing the conversion of carbon dioxide to bicarbonate and protons. Zinc ions have the appropriate coordination geometry and charge to facilitate this reaction efficiently. Iron (Fe) is not typically found in the active site of carbonic anhydrase enzymes. Calcium (Ca) and Magnesium (Mg) do not have the appropriate properties to serve as the catalytic metal ion in this enzyme. Therefore, zinc (Zn) is the correct answer due to its specific role and properties in the catalytic mechanism of carbonic anhydrase enzymes.
Question 5 of 5
A nurse in a medical unit is caring for a client with heart failure. The client suddenly develops extreme dyspnea,tachycardia and lung crackles. The nurse immediately asks another nurse to contact the primary health care provider and prepares to implement ALL priority interventions EXCEPT?
Correct Answer: C
Rationale: Rationale: Option C, transporting the client to the coronary care unit, is not the priority intervention because the client is presenting with acute pulmonary edema, a sign of worsening heart failure. Administering oxygen (Option A) is crucial to improve oxygenation. Administering furosemide (Option B) helps reduce fluid overload. Obtaining a stat Hepatic Panel (Option D) may be necessary to assess liver function due to medication side effects. However, immediate actions to address respiratory distress and tachycardia take precedence over moving the client to another unit.
