Multiple Choice Questions on Respiratory System Questions
Question 1 of 5
Plastron is the air bubble carrying respiratory air in the abdomen of
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The nurse has assessed a patient's family history for three generations. The presence of which respiratory disease would justify this type of assessment?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Asthma is a hereditary respiratory disease, making it important to assess family history. 2. Genetic predisposition plays a role in the development of asthma. 3. Understanding family history helps in identifying potential risk factors. 4. Obstructive sleep apnea, community-acquired pneumonia, and pulmonary edema are not typically hereditary respiratory diseases. 5. Therefore, assessing family history for three generations is justified for asthma.
Question 3 of 5
What is the relationship between the pressures at label '3'?
Correct Answer: B
Rationale: The correct answer is B because at label '3', the pressure outside the system is higher than the pressure inside. This is based on the principle that pressure decreases with increasing elevation. As we move upward in a fluid column, the pressure decreases. Therefore, in this scenario, the pressure outside the system (higher elevation) will be greater than the pressure inside the system (lower elevation). A: P outside = P inside - Incorrect, as explained above, pressures are not equal at label '3'. C: P outside < P inside - Incorrect, pressures are not in this relationship at label '3'. D: P outside + P inside - Incorrect, this is not a valid comparison of pressures at label '3'.
Question 4 of 5
Which of the following factors would increase the amount of oxygen discharged by hemoglobin to peripheral tissues?
Correct Answer: B
Rationale: The correct answer is B: decreased pH. A decrease in pH (increased acidity) causes a rightward shift in the oxygen-hemoglobin dissociation curve, facilitating the release of oxygen from hemoglobin to peripheral tissues. This occurs due to the Bohr effect, where a decrease in pH weakens the bond between hemoglobin and oxygen, allowing for easier oxygen release. Incorrect answers: A: Decreased temperature would actually shift the dissociation curve to the left, making it more difficult for oxygen to be released from hemoglobin. C: Increased tissue PO2 would lead to less oxygen being released from hemoglobin as the gradient for oxygen release decreases. D: Decreased amounts of BPG would result in less oxygen being released as BPG helps facilitate oxygen unloading from hemoglobin in tissues.
Question 5 of 5
Stimulation of the apneustic center would result in
Correct Answer: B
Rationale: The correct answer is B: more intense inhalation. The apneustic center is responsible for prolonging inhalation by stimulating the inspiratory neurons in the medulla oblongata. When the apneustic center is stimulated, it disrupts the normal breathing pattern, causing a prolonged and more intense inhalation. This results in deeper and more forceful breaths. Incorrect choices: A: increased respiratory rate - Stimulation of the apneustic center would not lead to an increased respiratory rate, but rather to changes in the depth and intensity of inhalation. C: a shorter respiratory cycle - The apneustic center's stimulation does not lead to a shorter respiratory cycle, but rather to a prolonged inhalation phase. D: less activity in the DRG center - The dorsal respiratory group (DRG) is responsible for initiating inspiration, and the apneustic center does not affect its activity.
