Respiratory System Questions and Answers PDF Questions
Question 1 of 5
Which of these statements is correct?
Correct Answer: D
Rationale: The correct answer is D because elastic fibers are more abundant in the bronchi and bronchioles than the upper respiratory tract. Elastic fibers provide elasticity and recoil to help with airway expansion and contraction during breathing. This is crucial in the bronchi and bronchioles to maintain airflow dynamics. Choice A is incorrect because regular bronchioles do not contain glands; they are found in the respiratory bronchioles. Choice B is incorrect because larynx contains a significant amount of cartilage, not smooth muscle. Choice C is incorrect because goblet cells are abundant in the larger bronchi, trachea, and bronchioles, not in the small bronchi and respiratory bronchioles.
Question 2 of 5
Rhea, confused and short breath, is brought to the emergency department by a family member. The medical history reveals chronic bronchitis and hypertension. To learn more about the current respiratory problem, the doctor orders a chest x-ray and arterial blood gas (ABG) analysis. When reviewing the ABG report, the nurses see many abbreviations. What does a lowercase in ABG value present?
Correct Answer: B
Rationale: The correct answer is B: Arterial Blood. The lowercase "a" in ABG values denotes arterial blood, indicating that the values are specific to the blood obtained from an artery. ABG analysis provides information about the oxygen and carbon dioxide levels in the blood, as well as the pH and bicarbonate levels, which are crucial in assessing respiratory and metabolic functions. Choice A: Acid-base balance - This is incorrect because the lowercase "a" in ABG does not represent acid-base balance. Acid-base balance is determined by the pH level in the blood, which is one of the parameters measured in ABG analysis. Choice C: Arterial oxygen saturation - This is incorrect because oxygen saturation is typically measured using pulse oximetry, not through ABG analysis. ABG values focus on the partial pressure of oxygen in the arterial blood. Choice D: Alveoli - This is incorrect because ABG values do not directly represent the condition of the alveoli. ABG analysis
Question 3 of 5
A nurse is suctioning fluids from a male client via a tracheostomy tube. When suctioning, the nurse must limit the suctioning time to a maximum of:
Correct Answer: C
Rationale: The correct answer is C: 10 seconds. Suctioning time for a tracheostomy tube should be limited to 10 seconds to prevent hypoxia and tissue damage. Prolonged suctioning can lead to decreased oxygenation and potential trauma to the airway. Choice A (1 minute) is too long and can cause harm. Choice B (5 seconds) is too short to effectively clear secretions. Choice D (30 seconds) exceeds the recommended time limit and can lead to complications. Therefore, limiting suctioning time to 10 seconds is the safest and most effective approach.
Question 4 of 5
A nurse is preparing to obtain a sputum specimen from a client. Which of the following nursing actions will facilitate obtaining the specimen?
Correct Answer: B
Rationale: Step 1: Taking deep breaths helps to bring sputum up from the lungs. Step 2: Coughing deeply helps to further bring sputum up. Step 3: This action facilitates the collection of a good sputum specimen. Step 4: Limiting fluids can make sputum thicker and harder to expectorate. Step 5: Asking the client to spit may result in saliva instead of sputum. Step 6: Asking for a specimen after eating can lead to contamination.
Question 5 of 5
Which of the following instructions should the nurse give a client about his active tuberculosis (TB)?
Correct Answer: D
Rationale: The correct answer is D because adherence to the medication regimen is crucial in treating active TB to prevent drug resistance and ensure successful treatment. Missing doses can lead to treatment failure and the spread of TB. Option A is incorrect because missing doses compromises treatment effectiveness. Option B is incorrect as stopping medication due to side effects can also result in treatment failure. Option C is incorrect because TB treatment must be completed as prescribed, regardless of symptom improvement.
