Respiratory System Questions Questions
Question 1 of 5
The amount of air normally inhaled or exhaled with one normal breath
Correct Answer: B
Rationale: The correct answer is B: Tidal volume. Tidal volume is the amount of air normally inhaled or exhaled with one normal breath. It represents the typical volume of air moved in and out of the lungs during normal breathing. The other choices are incorrect because: A) Expiratory reserve volume is the additional amount of air that can be exhaled after a normal exhalation; C) Residual volume is the volume of air remaining in the lungs after a maximum exhalation; D) Total lung capacity is the sum of all lung volumes, including tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume.
Question 2 of 5
The nurse is educating an asthma patient about proper use of the peak flowmeter. The nurse determines that the patient needs further teaching when observing which action?
Correct Answer: B
Rationale: The correct answer is B because breathing deeply through the mouthpiece can lead to incorrect peak flow readings. To explain further, deep breathing can artificially inflate the lungs and result in a higher peak flow reading than the patient's actual lung function. Therefore, this action would not provide an accurate assessment of the patient's peak flow. A: Repeating the procedure and obtaining three readings is correct as it helps ensure accuracy and consistency. C: Standing while performing the test is acceptable and does not affect the accuracy of the peak flow reading. D: Reporting the highest reading on the peak flow sheet is appropriate as it reflects the patient's best effort.
Question 3 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 4 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 5 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.
