Questions for Respiratory System Questions
Question 1 of 5
You are evaluating and assessing a client diagnosed with chronic emphysema. The client is on oxygen at a flow rate of 5 L/min by nasal cannula. Which finding concerns you immediately?
Correct Answer: B
Rationale: The correct answer is B. A respiratory rate of 8 breaths/minute is abnormally low and indicates potential hypoventilation or respiratory depression, which is concerning in a client with chronic emphysema. Fine crackles (A) and barrel chest (D) are common findings but not immediately alarming. Sitting up and leaning forward (C) is a compensatory mechanism for easier breathing.
Question 2 of 5
To determine whether a tension pneumothorax is developing in a patient with chest trauma, for what does the nurse assess the patient?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A nurse is caring for a client who is scheduled to undergo a thoracentesis. Which intervention should the nurse complete prior to the procedure?
Correct Answer: D
Rationale: The correct answer is D: Validate that informed consent has been given by the client. This is crucial before any invasive procedure to ensure the client fully understands the risks, benefits, and alternatives. This protects the client's autonomy and promotes ethical practice. Choice A is incorrect because measuring oxygen saturation before and after a 12-minute walk is not relevant to preparing for a thoracentesis. Choice B is incorrect because while it is important for the client to understand possible complications, verifying this understanding is not the priority before the procedure. Choice C is incorrect because explaining the procedure in detail to the client and family is important, but ensuring informed consent comes first to respect the client's autonomy.
Question 4 of 5
Dead air is not involved in respiration because
Correct Answer: D
Rationale: The correct answer is D because dead air is the air present in the alveoli that does not participate in gas exchange. It is located deep in the lungs, beyond the respiratory bronchioles where gas exchange occurs. Dead air does not reach the alveoli to participate in respiration. Choices A, B, and C are incorrect because the quantity of dead air or its oxygen content are not the primary reasons why it is not involved in respiration.
Question 5 of 5
Most of the Antibiotics against TB are not effective as the Tubercle bacterium has a resistive covering. One of the following drug is effectively used to control TB
Correct Answer: C
Rationale: Rationale for Correct Answer (C: Rifampicin): 1. Rifampicin is a first-line antibiotic for TB treatment. 2. It works by inhibiting RNA synthesis in the TB bacteria. 3. TB bacteria are less likely to develop resistance to Rifampicin. 4. Its effectiveness in treating TB has been well-documented. Summary of Why Other Choices Are Incorrect: A: Ethambutol - Effective against TB but not the most commonly used drug like Rifampicin. B: Streptomycin - Can be used in TB treatment but not as effective as Rifampicin. D: Penicillin - Ineffective against TB as TB bacteria are resistant to Penicillin.
