Respiratory System Test Questions Questions
Question 1 of 5
Which age-related changes in the respiratory system cause decreased secretion clearance?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Tracheal respiration is found in
Correct Answer: A
Rationale: Tracheal respiration is a type of respiration system found in insects and millipedes. This system involves the use of tracheae, which are tiny tubes that deliver oxygen directly to tissues. Insects and millipedes have evolved this efficient respiratory system to support their high metabolic rates. Scorpions and prawns (Choice B), Pila and lobsters (Choice C), and starfish and sea cucumbers (Choice D) do not have tracheal respiration systems. Therefore, the correct answer is A.
Question 3 of 5
Haldane effect refers to
Correct Answer: A
Rationale: The correct answer is A: Increased CO2 uptake to minimize CO2 tension. The Haldane effect describes how the blood's ability to carry CO2 increases as oxygen levels decrease. When oxygen binds to hemoglobin, it displaces CO2, allowing more CO2 to be carried by the blood. This phenomenon is crucial in the exchange of gases in the lungs and tissues. Choice B is incorrect as the Haldane effect is related to CO2, not O2 tension. Choice C is incorrect as the Haldane effect leads to increased CO2 uptake, not decreased. Choice D is incorrect as it states decreases O2 tension, which is not directly related to the Haldane effect.
Question 4 of 5
Hiccup is due to
Correct Answer: B
Rationale: The correct answer is B because hiccups are caused by the irritation of the phrenic nerve, which controls the diaphragm muscle responsible for breathing. When the nerve is irritated, it causes the diaphragm to contract involuntarily, leading to the characteristic sound of hiccups. Choice A (Increased inspiration) is incorrect as hiccups are not caused by increased inspiration but rather by involuntary contractions of the diaphragm. Choice C (Expanded stomach) is incorrect as hiccups are not directly related to the size of the stomach but rather to nerve irritation. Choice D (Acidity in the stomach) is incorrect as hiccups are not primarily caused by stomach acidity, but by nerve irritation leading to diaphragm contractions.
Question 5 of 5
The nurse doing rounds at the beginning of a shift notices a sputum specimen in a container sitting on the bedside table in a patient's room. The nurse asks the patient when he produced the sputum specimen and he states that the specimen is about 4 hours old. What action should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Discard the specimen and assist the patient in obtaining another specimen. It is important to discard the sputum specimen because it has been sitting for 4 hours, which could lead to contamination and inaccurate test results. The nurse should assist the patient in obtaining a fresh specimen to ensure accurate testing. Choice A is incorrect because taking the old specimen to the lab could lead to inaccurate results. Choice C is incorrect because refrigerating the old specimen won't prevent contamination. Choice D is incorrect because adding saline to the old specimen can alter its composition and lead to inaccurate test results.
