Multiple Choice Questions on Respiratory System Questions
Question 1 of 5
Chlorocruorin is a copper-containing blood pigment found in some annelids like Sabella. Its colour in both oxygenated and deoxygenated states is
Correct Answer: C
Rationale: Step 1: Chlorocruorin contains copper, giving it a green color. Step 2: In oxygenated state, chlorocruorin appears green due to the presence of copper. Step 3: In deoxygenated state, chlorocruorin retains its green color. Step 4: Therefore, the correct answer is C: Green. Summary: A (Blue) and B (Red) are incorrect as chlorocruorin is green due to copper. D (Blue red) is incorrect as it does not reflect the true color of chlorocruorin.

Question 3 of 5
A patient has been diagnosed with heart failure that has not yet responded to treatment. What breath sound should the nurse expect to assess on auscultation?
Correct Answer: D
Rationale: The correct answer is D: Crackles. In heart failure, crackles are often heard on auscultation due to fluid accumulation in the lungs. This is a result of the heart's inability to effectively pump blood, leading to congestion in the pulmonary circulation. Crackles are discontinuous, moist sounds that occur during inspiration and sometimes expiration. Expiratory wheezes (A) are typically associated with obstructive airway diseases such as asthma. Inspiratory wheezes (B) are not commonly heard in heart failure. Rhonchi (C) are low-pitched continuous sounds often heard in patients with bronchitis or pneumonia, not specifically in heart failure.
Question 4 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 5 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'.
