Exam Questions on Respiratory System Questions
Question 1 of 5
Hypoxia
Correct Answer: D
Rationale: The correct answer is D because hypoxia, which is a condition of low oxygen levels in the body, can indeed lead to hyperventilation, as the body tries to compensate. It can also cause symptoms like headaches, nausea, and lethargy due to the lack of oxygen reaching the brain and other organs. Severe hypoxia can lead to loss of consciousness and even death if oxygen levels are not restored promptly. Therefore, all the statements in choices A, B, and C are true in relation to hypoxia, making option D the correct choice.
Question 2 of 5
Oxygen dissociation curve of myoglobin is
Correct Answer: B
Rationale: The correct answer is B: Hyperbolic. Myoglobin exhibits a hyperbolic oxygen dissociation curve due to its high affinity for oxygen, allowing it to bind oxygen quickly and efficiently at low partial pressures. This curve represents a simple one-to-one binding relationship between myoglobin and oxygen. The other choices are incorrect because A (Hypobolic) does not accurately describe myoglobin's binding characteristics, C (Linear) is not representative of the typical oxygen binding behavior of myoglobin, and D (Sigmoid) is more characteristic of hemoglobin, which exhibits cooperative binding of oxygen.
Question 3 of 5
A nurse assesses a client's respiratory status. Which information is most important for the nurse to obtain?
Correct Answer: D
Rationale: The correct answer is D: Occupation and hobbies. This information is crucial as certain occupations or hobbies may expose the client to respiratory hazards, leading to potential respiratory issues. By assessing their occupation and hobbies, the nurse can identify any risks or triggers that could impact the client's respiratory status. A: Average daily fluid intake is important for overall health but not directly related to respiratory status assessment. B: Neck circumference may be relevant for assessing airway obstruction risk but is not as critical as occupation and hobbies. C: Height and weight are more related to general health and body mass index, not specifically respiratory status assessment.
Question 4 of 5
A home health nurse is visiting a new client who uses oxygen in the home. For which factors doesn't the nurse assess when determining if the client is using the oxygen safely?
Correct Answer: D
Rationale: The correct answer is D because household light bulbs being fluorescent type is unrelated to the safe use of oxygen. The nurse should assess factors directly related to oxygen safety, such as smoking restrictions, electrical cord condition, and proper storage of flammable materials. Fluorescent light bulbs do not pose a significant risk in relation to oxygen safety.
Question 5 of 5
A client has been diagnosed with tuberculosis (TB). What action by the nurse takes highest priority?
Correct Answer: A
Rationale: The correct answer is A because educating the client on adherence to the treatment regimen is the top priority in managing TB. This is crucial to prevent the spread of the disease and ensure successful treatment. Choice B is important for overall health but not the priority. Choice C is important but comes after starting treatment. Choice D is also important but does not directly impact the treatment outcome for TB.
