Questions About the Respiratory System With Answers Questions
Question 1 of 5
What is the initial antibiotic treatment for pneumonia based on?
Correct Answer: D
Rationale: The initial antibiotic treatment for pneumonia is typically based on the history, physical examination, and characteristic chest x-ray findings. This helps in identifying the specific causative organism and choosing the most appropriate antibiotic therapy. Gram stains and cultures may further confirm the diagnosis but are not typically used for initial treatment decisions.
Question 2 of 5
Tidal volume in Man is
Correct Answer: A
Rationale: The correct answer is A (500 ml) because tidal volume is the amount of air inhaled or exhaled during normal breathing. In an average adult man, the typical tidal volume is around 500 ml. Choices B, C, and D are incorrect because they represent volumes that are too high for tidal volume in a typical adult. Choice B (1500 ml) is too high and would be more in line with inspiratory reserve volume. Choice C (1200 ml) is also too high and would be closer to total lung capacity. Choice D (4500 ml) is significantly higher and would be more in line with vital capacity. Therefore, the correct answer is A (500 ml) as it aligns with the normal tidal volume during breathing.
Question 3 of 5
Advantage of Double Bohr effect is
Correct Answer: D
Rationale: The correct answer is D because the Double Bohr effect involves the reciprocal exchange of oxygen for carbon dioxide, leading to increased oxygenation of fetal blood and enhanced removal of carbon dioxide. This synergistic effect helps in efficient gas exchange during respiration. Option A is partially correct but doesn't encompass all the benefits of the Double Bohr effect. Option B is not entirely accurate as it focuses only on oxygenation without considering the role of carbon dioxide exchange. Option C is incorrect as it overlooks the oxygenation aspect of the Double Bohr effect. Therefore, the most comprehensive and accurate choice is D, as it encompasses all the advantages of the Double Bohr effect.
Question 4 of 5
The Bronchial tree is connected with the brain by
Correct Answer: D
Rationale: The correct answer is D: Vagus nerve. The vagus nerve is responsible for controlling the bronchial tree's smooth muscle and gland secretions, regulating breathing. It innervates the lungs and plays a crucial role in the parasympathetic control of the respiratory system. The other options (A: Trochlear nerve, B: Trigeminal nerve, C: Phrenic nerve) are not connected to the bronchial tree or involved in respiratory control.
Question 5 of 5
The nurse is caring for an elderly patient in the PACU. The patient has had a bronchoscopy, and the nurse is monitoring for complications related to the administration of lidocaine. For what complication related to the administration of large doses of lidocaine in the elderly should the nurse assess?
Correct Answer: C
Rationale: The correct answer is C: Confusion and lethargy. Lidocaine toxicity in the elderly can lead to central nervous system symptoms like confusion and lethargy due to impaired metabolism and clearance of the drug. The liver and kidney function decline with age, affecting lidocaine clearance. This can result in an accumulation of lidocaine leading to CNS symptoms. Choices A, B, and D are incorrect as they do not directly relate to lidocaine toxicity in the elderly. Decreased urine output and hypertension may be seen with other conditions like renal failure. Headache and vision changes are not typical symptoms of lidocaine toxicity. Jaundice and elevated liver enzymes may indicate liver dysfunction but are not specific to lidocaine toxicity.
