Nursing Clinical Practice Guide
Clinical Scenario: Mr. Chen, 45, is admitted to a medical ward with a confirmed diagnosis of active pulmonary TB. He is anxious about his diagnosis and the new medications. He has a history of social alcohol use.
Nursing Intervention Strategy:1. Assessment: Obtain baseline vital signs, especially temperature (fever common). Assess respiratory status (cough, sputum production, dyspnea). Perform a thorough medication and social history, including alcohol use. Check baseline liver function tests (LFTs: AST, ALT, Bilirubin) and a visual acuity baseline if Ethambutol is prescribed.2. Planning & Implementation:
* Initiate Airborne Precautions: Place patient in a negative pressure room. All staff and visitors must wear a fit-tested N95 respirator. Post signage.* Key Point! Medication Administration & Education: Administer first dose, observing for any immediate reactions. Provide clear, culturally appropriate education using teach-back method: "These medications must be taken every day for 6 to 9 months without missing a dose to cure you and prevent making the germs stronger. They can affect your liver, so you must watch for yellow skin or eyes, very dark urine, or severe tiredness and tell us immediately. Avoid all alcohol as it increases liver damage risk."* Arrange for Directly Observed Therapy (DOT) follow-up with the public health department upon discharge.3. Evaluation: Monitor patient for understanding of teaching (verbalizes key side effects and adherence importance). Monitor LFTs per protocol. Assess for clinical improvement (decreased cough, fever).
Patient Safety and Precautions: Watch out for confusion! Do not administer Pyrazinamide if the patient has severe gout or hepatic disease. Ethambutol is contraindicated in patients unable to report visual changes (e.g., young children). Always verify that sputum samples for AFB smear are collected in the early morning, deep cough specimens.
Nursing Procedure & Medication Flow
Medication Administration for TB (Example: 4-drug regimen):
* Verify order: INH, RIF, PZA, EMB.
* Assess: Check recent LFTs. Ask patient about alcohol use in last 24 hours. Assess for signs of active hepatitis.
* Administer: Usually all drugs are given orally once daily, preferably on an empty stomach (1 hour before or 2 hours after meals) for best absorption, unless GI upset occurs (then can give with food).
* Patient Education Points:
* Take consistently at the same time.
* Rifampin turns urine, sweat, and tears orange-red; it will stain soft contact lenses.
* Report any of these immediately: Nausea/vomiting/loss of appetite, yellow eyes/skin, dark "cola-colored" urine, unexplained fatigue, pain over the liver, blurred vision or color blindness, joint pain (gout-like from PZA).
* Use non-hormonal contraception if on Rifampin, as it reduces efficacy of oral contraceptives.
A Word from Your Senior Nurse
"Managing a TB patient perfectly blends the art of infection control, pharmacology vigilance, and therapeutic communication. That initial conversation about hepatotoxicity isn't just a checkbox—it builds the trust necessary for a 9-month treatment partnership. In clinicals, if you see a patient on INH, always glance at their sclera when you say hello. That simple assessment could catch early jaundice. For the NCLEX, remember: with TB, think Safety (Liver) + Adherence (DOT). That mindset will guide you to the right answer every time."
