Which symptom could indicate lactic acidosis in patients taking some NRTIs?

• A. Nausea, but no abdominal pain or respiratory symptoms
• B. Abdominal pain only
• C. Rapid breathing only
• D. Nausea, abdominal pain, and rapid breathing

Answer: (D)

Lactic acidosis from some NRTIs happens because these drugs can cause mitochondrial toxicity, leading to an accumulation of lactic acid and a metabolic acidosis. When this develops, the body often tries to compensate with rapid breathing to blow off CO2, and patients commonly report nausea and abdominal pain. Because the metabolic disturbance produces both GI symptoms and a respiratory response, the combination of nausea, abdominal pain, and rapid breathing best signals lactic acidosis in someone taking NRTIs. If a patient on NRTIs develops these symptoms, it’s important to assess lactate levels and blood gas status and to consider stopping the offending drug if lactic acidosis is suspected. Single symptoms like nausea alone, abdominal pain alone, or rapid breathing alone can occur from many causes, but together they point more strongly to this specific adverse effect in the context of NRTI therapy.
