Questions About the Respiratory System Questions
Question 1 of 5
The left lung has two lobes and they are separated by Deep fissure called .
Correct Answer: B
Rationale: The correct answer is B: oblique fissure. The left lung has two lobes, the upper lobe and the lower lobe, which are separated by the oblique fissure. This fissure extends obliquely downward and forward from the posterior border of the lung. Rationale: 1. The horizontal fissure separates the right lung into upper and middle lobes, not the left lung. 2. There is no such structure as a vertical fissure in the human lung anatomy. 3. "Non of them" is grammatically incorrect and does not provide a valid option.
Question 2 of 5
The nurse is preparing a presentation that highlights the benefits of annual influenza vaccination. The nurse correctly targets which groups Except?
Correct Answer: A
Rationale: The correct answer is A because children aged 3 to 6 months are too young to receive the influenza vaccine. They are not recommended for vaccination until they reach 6 months of age. Choice B is correct as older diabetics are at higher risk for complications from the flu. Choice C is correct as pregnant women are a high-risk group for flu-related complications. Choice D is correct as home health aides are in close contact with vulnerable populations.
Question 3 of 5
A client has returned to the coronary care unit after having a coronary angiogram. Which assessment data indicate the need for immediate action by the nurse?
Correct Answer: A
Rationale: The correct answer is A: Diminished pedal pulse volume. This indicates potential circulation compromise, which can lead to ischemia or impaired tissue perfusion. Immediate action is required to prevent further complications. B: Heart rate 100 beats/min is within normal range. C: Blood pressure 104/60 mm Hg is slightly low but not critically concerning. D: Capillary refill less than 3 seconds indicates good peripheral perfusion.
Question 4 of 5
The nurse has instructed the client on how to obtain a sputum culture. Which of the statements indicates that the client understood the instruction from the nurse?
Correct Answer: D
Rationale: The correct answer is D because the client demonstrates understanding by acknowledging the need to breathe deeply and cough up the sputum to obtain a sputum culture. This action helps bring up the lower respiratory tract secretions for an accurate culture. Choice A is incorrect because increasing fluids actually helps in sputum production. Choice B is incorrect as mouth care should be done before to prevent contamination. Choice C is incorrect as early morning is the best time due to the accumulation of secretions overnight.
Question 5 of 5
Which of the following substances is activated by passage through the pulmonary circulation?
Correct Answer: D
Rationale: The correct answer is D: Angiotensin 1. When blood passes through the pulmonary circulation, angiotensinogen is converted into angiotensin 1 by the enzyme renin. This activation occurs in the lungs. Bradykinin, serotonin, and noradrenaline are not activated in the pulmonary circulation. Bradykinin is a peptide released during inflammation, serotonin is a neurotransmitter, and noradrenaline is a neurotransmitter and hormone. Therefore, D is the only substance activated by passage through the pulmonary circulation.
