Questions for the Respiratory System Questions
Question 1 of 5
Partial pressure of oxygen in the inspired and expired air is respectively
Correct Answer: A
Rationale: The correct answer is A (158 and 116 mm Hg) because in inspired air, the partial pressure of oxygen is around 158 mm Hg, which corresponds to the atmospheric oxygen level. During expiration, some oxygen is exchanged for carbon dioxide, leading to a decrease in oxygen partial pressure to around 116 mm Hg. Choice B is incorrect because the partial pressure of oxygen in expired air is not as high as 40 mm Hg, which is too low for the oxygen content in the air we breathe. Choice C is incorrect because the partial pressure of oxygen in inspired air is not exactly 100 mm Hg, and the partial pressure in expired air is not as close to 95 mm Hg. Choice D is incorrect because the partial pressure of oxygen in inspired air is not as low as 40 mm Hg, and the partial pressure in expired air is not as high as 95 mm Hg.
Question 2 of 5
A client with a new tracheostomy is being seen in the oncology clinic. What finding by the nurse best indicates that goals for the client's decrease in self-esteem are being met?
Correct Answer: B
Rationale: The correct answer is B because joining a book club shows an improvement in social engagement and participation, indicating an increase in self-esteem. This choice demonstrates the client's interest in activities outside of their healthcare needs, promoting a sense of normalcy and connection. In contrast, options A, C, and D focus solely on stoma care and physical aspects, not directly related to self-esteem. Understanding stoma care (A) is important but does not address self-esteem directly. Family assistance (C) is supportive but does not necessarily indicate an improvement in the client's self-esteem. Skin integrity (D) is essential for physical health but does not reflect self-esteem.
Question 3 of 5
A client is in the family practice clinic reporting a severe cold that started 4 days ago. On examination the nurse notes that the client also has a severe headache and muscle aches. What action by the nurse is best?
Correct Answer: D
Rationale: The correct answer is D: Teach the client to sneeze in the upper sleeve. This action is best because the client is showing symptoms of a cold, which is typically caused by a virus spread through respiratory droplets. Instructing the client to sneeze in the upper sleeve can help prevent the spread of the virus to others. Choice A is incorrect because oseltamivir is used to treat influenza, not the common cold. Choice B is unnecessary as hospital admission is not typically warranted for a cold. Choice C is also incorrect as the client is already sick and a flu vaccine would not be effective at this point in time.
Question 4 of 5
In general, when looking at acid-base balance, how does the body compensate with metabolic acidosis?
Correct Answer: A
Rationale: The correct answer is A. In metabolic acidosis, the lungs compensate by increasing respiratory rate and depth ('blowing off' CO2) to reduce acidity and raise pH. B is incorrect because retaining CO2 would worsen acidosis. C is partially true long-term but slower acting than pulmonary compensation. D is incorrect because excreting bicarbonate lowers pH further.
Question 5 of 5
The nursing assistant tells you that the client on oxygen at a flow rate of 6 L/min by nasal cannula is complaining of nasal passage discomfort. What intervention should you suggest to improve the client's comfort for this problem?
Correct Answer: A
Rationale: The correct answer is A. Humidifying oxygen reduces nasal dryness and irritation caused by high-flow oxygen through a nasal cannula. Using a face mask (B) might help but is less practical for long-term use. Providing an extra pillow (C) or sitting up in a chair (D) does not address the nasal discomfort directly.
