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?

A.

Decreased cough and sputum.

B.

A positive sputum smear and culture.

C.

Decreased appetite and weight loss.

D.

Vertigo and tinnitus.

Answer and Explanation

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 C

Explanation

Choice A rationale

Lansoprazole, a proton pump inhibitor (PPI), typically requires several weeks to achieve its full therapeutic effect. Notifying the healthcare provider for a dosage change after only one week is premature and not supported by clinical guidelines.

Choice B rationale

Auscultating bowel sounds and measuring abdominal girth are not directly related to the effectiveness of lansoprazole in treating GERD. These actions are more relevant for assessing gastrointestinal motility and potential complications like bowel obstruction.

Choice C rationale

Healing of erosive esophagitis with PPIs like lansoprazole usually takes several weeks. Advising the client that healing typically takes several weeks to occur is appropriate and aligns with the expected therapeutic timeline.

Choice D rationale

Lansoprazole should be taken before meals, not after, to maximize its effectiveness. Confirming that the client is taking the medication one hour after meals would not address the issue of symptom persistence.

Correct Answer is D

Explanation

Choice A rationale

Total protein levels are not directly related to the symptoms of pallor and fatigue. While important, they do not provide immediate insight into the client’s current condition.

Choice B rationale

Sodium levels are crucial for overall health but are not directly related to the symptoms of pallor and fatigue. Monitoring sodium is important for fluid balance but not for diagnosing anemia.

Choice C rationale

Glucose levels are essential for managing diabetes and other metabolic conditions but are not directly related to the symptoms of pallor and fatigue. Monitoring glucose is important for overall health but not for diagnosing anemia.

Choice D rationale

Hemoglobin levels are directly related to the symptoms of pallor and fatigue. Diclofenac, an NSAID, can cause gastrointestinal bleeding, leading to anemia. Therefore, reviewing hemoglobin levels is crucial in this scenario.
