Questions Respiratory System Questions
Question 1 of 5
Phrenic nerve are
Correct Answer: C
Rationale: The phrenic nerve innervates the diaphragm and arises from cervical nerve roots C3 to C5. Choice C is correct as it accurately states that the phrenic nerve is located in the diaphragmatic area and originates from C3 to C5. Choice A is incorrect as it only mentions the diaphragmatic area without specifying the cervical levels. Choice B is incorrect as it only mentions the cervical levels without specifying the diaphragmatic area. Choice D is incorrect as the phrenic nerve does exist.
Question 2 of 5
The nurse is caring for a client who is one hour post cardiac catheterization. What task should the nurse delegate to a licensed practical/vocational nurse (LPN/VN)?
Correct Answer: C
Rationale: The correct answer is C: Give the scheduled lipid-lowering medication. LPN/VNs can administer medications, including lipid-lowering drugs, under the supervision of a registered nurse. Teaching (choice A) requires a higher level of critical thinking and education, which is typically done by an RN. Performing an initial assessment (choice B) requires advanced assessment skills that an LPN/VN may not have. Titration of medications (choice D) involves adjusting dosages based on specific parameters, which is beyond the scope of practice for an LPN/VN.
Question 3 of 5
A client with bronchitis is admitted to the hospital. What would the nurse expect the admitting assessment NOT to reveal?
Correct Answer: D
Rationale: The correct answer is D: Bradycardia. In bronchitis, the body typically responds to inflammation by increasing heart rate (tachycardia) to improve oxygen delivery. Bradycardia is not a common finding in bronchitis and would be unexpected. Choices A, B, and C are commonly associated with bronchitis due to the inflammation in the airways causing cough, production of bloody sputum, and chest pain. These symptoms are typical manifestations of bronchitis and would be expected in the admitting assessment.
Question 4 of 5
All of the following pairings are correct (assuming normal person at rest) EXCEPT
Correct Answer: B
Rationale: The correct answer is B: Alveolar ventilation = 7500 ml. Alveolar ventilation is the volume of fresh air that reaches the alveoli per minute. It is calculated by subtracting the dead space ventilation from the tidal volume and then multiplying by the respiratory rate. In a normal person at rest, the average alveolar ventilation is around 4200 ml/min, not 7500 ml/min. Therefore, choice B is incorrect. Choices A, C, and D are correct because tidal volume is typically around 500 ml, pulmonary blood flow is about 5000 ml/min, and functional residual capacity is the volume of gas in the lung after normal expiration.
Question 5 of 5
Miriam, a college student with acute rhinitis sees the campus nurse because of excessive nasal drainage. The nurse asks the patient about the color of the drainage. In acute rhinitis, nasal drainage normally is:
Correct Answer: C
Rationale: The correct answer is C: Clear. In acute rhinitis, the nasal drainage is typically clear because it is caused by viral infections or allergies, which result in clear mucus production. Yellow or green drainage may indicate a bacterial infection, which is not typically associated with acute rhinitis. Gray drainage is uncommon in nasal discharge and may suggest a more serious underlying condition. Therefore, the nurse asked about the color of the drainage to assess the nature of the infection and determine the appropriate course of treatment.
