The antitubercular drug isoniazid is prescribed for a client with active tuberculosis. To evaluate the effectiveness of this medication, which outcome can the nurse expect this client to exhibit?
Decreased cough and sputum.
A positive sputum smear and culture.
Decreased appetite and weight loss.
Vertigo and tinnitus.
The Correct Answer is A
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.

Correct Answer is D
Explanation
Choice A rationale
Observing pupil response of the right eye is not relevant to the care of the left eye post-cataract extraction.
Choice B rationale
Sleeping flat in a supine position is not recommended as it can increase intraocular pressure. Elevating the head is advised.
Choice C rationale
Turning, coughing, and deep breathing every 2 hours is not specific to cataract surgery and can increase intraocular pressure.
Choice D rationale
Administering a stool softener is important to prevent straining during bowel movements, which can increase intraocular pressure and affect healing.
Correct Answer is A
Explanation
Choice A rationale
Tiotropium is a long-acting bronchodilator used daily to manage chronic obstructive pulmonary disease (COPD). It helps to relax the muscles around the airways, making it easier to breathe. This medication is not intended for immediate relief of acute symptoms but for long-term control of COPD1.
Choice B rationale
Using another inhaler in between uses of tiotropium is not necessary unless prescribed by a healthcare provider. Tiotropium is meant to be used daily, and other inhalers may be prescribed for different purposes, such as rescue inhalers for sudden symptoms.
Choice C rationale
While tiotropium can help improve breathing and reduce symptoms over time, it is not specifically indicated to reduce the thickness of sputum. Other medications or treatments may be needed to address sputum consistency.
Choice D rationale
Tiotropium is not a rescue inhaler and should not be used for sudden shortness of breath. Rescue inhalers, such as albuterol, are designed for immediate relief of acute symptoms.
