The nurse is caring for a client with emphysema who is mildly dyspneic after ambulation. Which instruction should the nurse provide to the client to improve gas exchange?
Lay down on each side with knees bent and breathe from abdomen.
Increase breathing rate for a full 30 seconds.
Raise hands above the head to expand the diaphragm.
Draw air in through nose and exhale slowly through pursed lips.
The Correct Answer is D
Choice A rationale
Laying down on each side with knees bent and breathing from the abdomen is not an effective technique for improving gas exchange in emphysema patients.
Choice B rationale
Increasing the breathing rate for a full 30 seconds can lead to hyperventilation and is not recommended for improving gas exchange.
Choice C rationale
Raising hands above the head to expand the diaphragm is not a recognized technique for improving gas exchange in emphysema patients.
Choice D rationale
Drawing air in through the nose and exhaling slowly through pursed lips is an effective technique for improving gas exchange in emphysema patients. This method helps to keep the airways open longer and improves the removal of trapped air.

Correct Answer is A
Explanation
Choice A rationale
Isolating the client from others is the most important action to prevent the spread of COVID-19. This includes isolating the client from other clients, family, and healthcare workers not wearing proper PPE2.
Choice B rationale
Reporting the COVID-19 result to the local health department is important but not the immediate priority. Isolation takes precedence to prevent transmission.
Choice C rationale
Teaching the client to wear a mask, hand wash, and social distance is essential but secondary to immediate isolation.
Choice D rationale
Counseling family members to monitor for symptoms is important but not the immediate priority. Isolation of the client is the first step.
Correct Answer is A
Explanation
Choice A rationale
Isoniazid is an antitubercular drug used to treat active tuberculosis. The effectiveness of this medication is evaluated by observing a decrease in symptoms such as cough and sputum production. This indicates that the infection is being controlled and the bacteria are being eradicated.
Choice B rationale
A positive sputum smear and culture would indicate the presence of active tuberculosis bacteria, suggesting that the treatment is not effective. Therefore, this is not an expected outcome of effective treatment.
Choice C rationale
Decreased appetite and weight loss are not indicators of the effectiveness of tuberculosis treatment. In fact, these symptoms could indicate a worsening of the condition or side effects of the medication.
Choice D rationale
Vertigo and tinnitus are not related to the effectiveness of tuberculosis treatment. These symptoms could be side effects of the medication but do not indicate the success of the treatment.
