Questions on Respiratory System Questions
Question 1 of 5
How many layers of pleura have
Correct Answer: A
Rationale: Step 1: Pleura is a thin membrane that surrounds the lungs and lines the chest cavity. Step 2: There are two layers of pleura - visceral (inner layer covering the lungs) and parietal (outer layer lining the chest cavity). Step 3: The correct answer is A (2), because there are only two layers of pleura. Summary: Choice B and C are incorrect because they each represent only one layer of pleura, whereas the correct answer A encompasses both layers. Choice D is incorrect because it includes all options, which is not accurate in this case.
Question 2 of 5
The nurse is developing a teaching plan for a 64-year-old client with coronary artery disease (CAD). Which factor should the nurse focus on during the teaching session?
Correct Answer: B
Rationale: The correct answer is B: Elevated low-density lipoprotein (LDL) level. This is the most relevant factor to focus on during the teaching session for a client with CAD. Elevated LDL levels are a major risk factor for the development and progression of CAD. By addressing this factor, the nurse can educate the client on the importance of managing cholesterol levels through diet, exercise, and medication. Incorrect choices: A: Family history of CAD - While family history is a risk factor, it cannot be modified through education alone. C: Greater risk associated with the patient's gender - Gender is a non-modifiable risk factor and not the primary focus for teaching. D: Increased risk of cardiovascular disease with aging - While age is a risk factor, the focus should be on modifiable risk factors like LDL levels.
Question 3 of 5
The nurse supervises unlicensed assistive personnel (UAP) providing care for a client who has right lower lobe pneumonia. Which action by the UAP requires the nurse to intervene?
Correct Answer: D
Rationale: Correct Answer: D Rationale: 1. In right lower lobe pneumonia, positioning the client with the affected side down helps improve ventilation and drainage. 2. Lowering the head of the bed to 15 degrees promotes pooling of secretions, worsening respiratory status. 3. A, B, and C are appropriate actions that promote client comfort and safety in pneumonia management. 4. Intervening in option D is crucial to prevent complications and promote effective respiratory care.
Question 4 of 5
How much does the inspired O2 concentration have to be raised to abolish the hypoxaemia?
Correct Answer: B
Rationale: The correct answer is B (7%). To abolish hypoxemia, inspired O2 concentration needs to be increased sufficiently to raise arterial oxygen levels. A 7% increase is generally effective in achieving this without causing oxygen toxicity. Choices A, C, and D are incorrect because a 5% increase may not be enough to abolish hypoxemia, a 10% increase can lead to oxygen toxicity, and a 15% increase is excessive and unnecessary for treating hypoxemia. Therefore, option B is the most appropriate and balanced choice for addressing hypoxemia effectively.
Question 5 of 5
The organ of the respiratory system that traps bacteria with a ring of tonsils is the:
Correct Answer: B
Rationale: The correct answer is B: pharynx. The pharynx is the organ that traps bacteria with its tonsils. The tonsils are located in the pharynx and act as the body's first line of defense against pathogens entering the respiratory system. The nose (choice A) is responsible for warming, humidifying, and filtering air, but it does not trap bacteria with tonsils. The larynx (choice C) is involved in sound production and preventing food from entering the airway, not trapping bacteria. The trachea (choice D) is the windpipe that carries air to and from the lungs, but it does not have tonsils to trap bacteria.
