Respiratory System NCLEX Questions Questions
Question 1 of 5
Following an asthmatic attack, a mother asks the physician how to prevent another asthmatic attack. The physician should:
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A nurse cares for a client who had a bronchoscopy 2 hours ago. The client asks for a drink of water. Which action should the nurse take next?
Correct Answer: C
Rationale: Correct Answer: C Rationale: 1. Assessing the client's gag reflex is crucial after a bronchoscopy to prevent aspiration. 2. Gag reflex helps protect the airway from foreign substances entering the lungs. 3. Providing food or water without assessing the gag reflex can lead to aspiration pneumonia. 4. It is essential to ensure the client's safety before allowing any intake post-bronchoscopy. Summary: A: Calling the physician for a prescription is not necessary at this immediate stage. B: Ice chips may still pose a risk if the client cannot protect their airway. D: Allowing a sip without assessing gag reflex may lead to aspiration.
Question 3 of 5
Pneumotaxic center is
Correct Answer: A
Rationale: The correct answer is A: Inhibitory. The pneumotaxic center is located in the upper pons and functions to inhibit inspiration, preventing overinflation of the lungs. This helps regulate the respiratory rate and depth. The other choices are incorrect because the pneumotaxic center does not accelerate or activate breathing directly. It exerts its influence by inhibiting the inspiratory neurons in the medulla, thereby controlling the duration and frequency of inspiration. Choice D is incorrect as the pneumotaxic center does have a specific inhibitory function in the respiratory control system.
Question 4 of 5
Carbonic anhydrase in the RBC is the fastest enzyme and it decomposes in one second for fast action. Its concentration in the blood is due to the presence of
Correct Answer: D
Rationale: The correct answer is D: Hemoglobin. Carbonic anhydrase is an enzyme found in red blood cells that rapidly catalyzes the conversion of carbon dioxide into bicarbonate ions. Hemoglobin plays a crucial role in transporting carbon dioxide in the blood. The high concentration of hemoglobin in red blood cells allows for efficient binding and transport of carbon dioxide, leading to the need for a rapid enzyme like carbonic anhydrase to facilitate its conversion. Plasma (choice A) does not directly influence the concentration of carbonic anhydrase. Carbon dioxide (choice B) is the substrate for carbonic anhydrase, not the reason for its concentration. Sodium ions (choice C) do not directly affect the action of carbonic anhydrase in red blood cells.
Question 5 of 5
The nurse is caring for a patient who has returned to the unit following a bronchoscopy. The patient is asking for something to drink. Which criterion will determine when the nurse should allow the patient to drink fluids?
Correct Answer: A
Rationale: The correct answer is A, presence of a cough and gag reflex. After a bronchoscopy, it is crucial for the nurse to ensure the patient has a cough and gag reflex before allowing them to drink fluids to prevent aspiration. Cough reflex helps clear secretions, and gag reflex prevents fluids from entering the airway. Choices B, C, and D are incorrect as they do not directly relate to the safety of the patient's ability to swallow post-bronchoscopy.
