Questions on Respiratory System Questions
Question 1 of 5
larynx have how many cartilages?
Correct Answer: C
Rationale: The larynx consists of 9 cartilages, including the thyroid, cricoid, and epiglottis. These structures provide support and protection to the vocal cords and are essential for phonation and breathing. Choice C is correct because it accurately reflects the number of cartilages in the larynx. Choices A, B, and D are incorrect as they do not correspond to the anatomical structure of the larynx. It is important to understand the specific components of the larynx to correctly identify the number of cartilages present.
Question 2 of 5
The nurse is performing an occupational history as part of the respiratory assessment. Which occupation(s) place the patient isn't at increased risk for an occupational lung disorder?
Correct Answer: D
Rationale: The correct answer is D: A bartender. Bartenders are not typically exposed to occupational lung hazards like smoke, dust, or chemicals. Firefighters (A), cotton gin workers (B), and construction contractors (C) are all at increased risk due to exposure to smoke, cotton dust, and construction materials, respectively. As a result, the bartender is the least likely to develop an occupational lung disorder compared to the other professions listed.
Question 3 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 4 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 5 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.
