Respiratory System Questions Questions
Question 1 of 5
The anatomical position of hilum
Correct Answer: D
Rationale: The correct answer is D. The hilum is the region where blood vessels, nerves, and lymphatics enter and exit an organ. The anatomical position of the hilum can vary depending on the organ. For example, in the lungs, the hilum is located in the mediastinal surface between the lungs, around the level of the 6th to 7th thoracic vertebrae. Therefore, option D, "all of these," is correct because it encompasses the different anatomical positions of the hilum in various organs. Options A, B, and C are incorrect because they do not fully capture the diverse locations of the hilum in different anatomical contexts.
Question 2 of 5
While obtaining subjective assessment data from a patient with hypertension the nurse recognizes that a modifiable risk factor for the development of hypertension is?
Correct Answer: B
Rationale: The correct answer is B: Excess alcohol intake. Alcohol consumption can contribute to the development of hypertension by increasing blood pressure and damaging the arteries over time. Excessive alcohol intake can also lead to weight gain and other unhealthy lifestyle choices that can exacerbate hypertension. A: A low-calcium diet is not a modifiable risk factor for the development of hypertension. Calcium intake may have some impact on blood pressure regulation, but it is not a primary modifiable risk factor for hypertension. C: A family history of hypertension is a non-modifiable risk factor as genetics play a significant role in the development of hypertension. While having a family history of hypertension increases one's risk, it is not something that can be changed or modified. D: Consumption of a high-protein diet is not a primary modifiable risk factor for hypertension. While diet plays a role in hypertension, high protein intake alone is not a significant risk factor compared to factors such as excessive alcohol consumption, high sodium intake, and obesity
Question 3 of 5
Which action should the nurse take to prepare a client with a pleural effusion for a thoracentesis?
Correct Answer: C
Rationale: The correct action is to position the client sitting up on the side of the bed. This position allows for easier access to the pleural space during the thoracentesis procedure. Sitting up also helps to expand the intercostal spaces, making it easier for the healthcare provider to locate the fluid collection. Choice A is incorrect as fasting is not typically required for a thoracentesis procedure. Choice B is unnecessary as sedation is not routinely used for this procedure. Choice D is incorrect as the amount of pleural fluid to be removed varies and a specific collection device is not always needed. In summary, positioning the client sitting up on the side of the bed is the most appropriate action to prepare for a thoracentesis procedure, as it facilitates access and fluid removal.
Question 4 of 5
A man with normal lungs and arterial pCO2 of 40mmHg takes an overdose of barbiturates,which half his ventilation but don't change his CO2 output. What does his arterial pCO2 rise to?
Correct Answer: D
Rationale: The correct answer is D: 80mmHg. When a person takes an overdose of barbiturates that reduce ventilation but not CO2 output, it leads to respiratory depression. This causes retention of CO2 in the body, leading to hypercapnia. With normal lungs and initial arterial pCO2 of 40mmHg, a rise to 80mmHg is expected due to the decreased ventilation. The other choices are incorrect because they do not account for the significant impact of reduced ventilation on CO2 retention in this scenario. Choice A, 70mmHg, is too low of a rise considering the drastic reduction in ventilation. Choices B and C, 50mmHg and 60mmHg, respectively, do not adequately reflect the extent of hypercapnia that occurs with respiratory depression.
Question 5 of 5
The organs of the conducting zone of the respiratory system include all the following EXCEPT:
Correct Answer: D
Rationale: The correct answer is D: alveoli. The conducting zone of the respiratory system consists of structures that conduct air to and from the gas exchange surfaces. Alveoli are the site of gas exchange, not part of the conducting zone. The nose (A), trachea (B), and bronchi (C) are all part of the conducting zone as they help transport air to the lungs. Alveoli are where oxygen and carbon dioxide exchange occurs during respiration.
