Which of the following signs and symptoms indicates salicylate toxicity?

Appeared in: GMCH Chandigarh - 2019

Explanation

Ringing in the ears (tinnitus) is a hallmark early symptom of salicylate toxicity, also known as salicylism.
This symptom arises from the drug's effect on the auditory nerve (cranial nerve VIII) and central nervous system.
It is considered a key warning sign that salicylate levels in the blood are becoming dangerously high.
The appearance of tinnitus often precedes more severe symptoms like hyperventilation, acid-base disturbances, and altered mental status.

Option A: Chest pain is not a characteristic sign of salicylate toxicity. Its presence would prompt investigation into cardiac, pulmonary, or gastrointestinal causes.
Option B: Pink-colored urine, which may indicate hematuria, is not a classic or common sign of salicylate toxicity. While severe toxicity can impair renal function, this is not a primary diagnostic clue.
Option C: A slow pulse rate (bradycardia) is contrary to the expected findings in salicylate toxicity. The condition typically causes an increased heart rate (tachycardia) due to metabolic stress, dehydration, and hyperthermia.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Recognition of salicylate toxicity symptoms as background academic context rather than a clinical decision trigger.
A nurse must educate patients on long-term or high-dose aspirin therapy to immediately report any ringing in their ears, as it is a critical sign of toxicity.
Prompt recognition of tinnitus allows for early intervention, such as holding the medication and notifying the provider, which can prevent life-threatening complications like severe acid-base imbalance and seizures.
What if the patient is a child? Children may not be able to clearly report tinnitus. Instead, they might present with hyperventilation, lethargy, or behavioral changes as the primary signs of toxicity. Nurses should have a high index of suspicion in this population.

How to Approach the Question

First, identify the core of the question, which is asking for a specific sign of 'salicylate toxicity'.
Recall the classic symptoms associated with aspirin overdose (salicylism). Think about the common side effects taught in pharmacology.
Evaluate each option based on your knowledge. Tinnitus (ringing in ears) is a well-known, textbook symptom of salicylate toxicity.
Eliminate the other options. Chest pain, pink urine, and slow pulse are not primary or expected signs of this specific toxicity.
Confirm your choice. Ringing in the ears is the most direct and common indicator of salicylism among the given choices.
