A patient was diagnosed as a case of pulmonary tuberculosis. He was started anti tuberculous therapy. He complains of red color urine. What to do?

Appeared in: NCL (MP) Nursing Officer - 2020

Explanation

Red or orange discoloration of urine is a common, expected, and harmless side effect of Rifampicin, a first-line anti-TB drug.
This effect occurs because the drug and its metabolites are colored and are excreted through bodily fluids, including urine, tears, and sweat.
The phenomenon is benign and does not indicate a pathological condition like bleeding (hematuria) or infection.
The most appropriate initial nursing action is to provide education and reassurance to the patient, which alleviates their anxiety and promotes crucial medication adherence.

Option A: This is incorrect because the urine color change is a known pharmacological effect of Rifampicin, not a sign of pathology. A routine exam is not needed without other signs like pain or clots.
Option B: This is incorrect as there are no signs or symptoms of a urinary tract infection (UTI), such as fever, dysuria (painful urination), or increased frequency, which would necessitate a culture.
Option C: This is incorrect as there is no indication of a structural or pathological problem of the urinary tract that would require a surgical opinion. The complaint is directly related to medication.

Clinical Relevance

Nursing practice connection: Use the key finding related to Management of common side effects of Anti-Tuberculous Therapy (ATT) to guide bedside assessment, documentation, and the next nursing action.
Patient education on medication side effects is a critical nursing responsibility to ensure adherence to long-term therapy like ATT. Non-adherence can lead to treatment failure and the development of drug-resistant TB.
Failure to properly counsel the patient about this harmless side effect may cause them to prematurely stop their life-saving medication out of fear, with serious public and personal health consequences.
What if? If the patient reported red urine along with flank pain, fever, and painful urination, the correct answer would change. The priority would then be to send the urine for routine examination and culture to rule out a concomitant UTI, while still providing counseling about the Rifampicin effect.

How to Approach the Question

Identify the core clinical scenario: A patient on a specific, long-term therapy (ATT for TB) presents with a new symptom.
Analyze the symptom in the context of the treatment: 'Red color urine' is a hallmark, well-known side effect of a common medication used in the treatment regimen.
Recall the pharmacology of first-line anti-TB drugs. Specifically, remember that Rifampicin causes a harmless orange-red discoloration of body fluids.
Evaluate the options based on this knowledge. Is the complaint a sign of a dangerous condition or an expected, benign side effect?
Determine the most appropriate action. Since it's an expected, harmless side effect, the primary intervention should be educational and supportive to prevent patient anxiety and non-adherence.
Select the option that reflects patient education and reassurance (counseling) over unnecessary investigations or referrals.
