Appeared in: JIPMER Nursing Officer - 2020

Explanation

Oral fluorosis is a developmental disturbance of dental enamel, not a side effect of radiation therapy.
It is caused by excessive ingestion of fluoride during the first eight years of life when permanent teeth are forming.
This condition is entirely unrelated to the mechanisms of radiation, which damages cells in the treatment field.

Option A: Mucositis is a very common and expected acute side effect of radiation to the head and neck, as radiation damages the rapidly dividing cells of the oral mucosa.
Option B: Xerostomia (dry mouth) is a common acute and often chronic side effect that occurs when salivary glands are damaged by the radiation field.
Option C: Trismus (restricted jaw opening) is a known late side effect of head and neck radiation, caused by radiation-induced fibrosis of the masticatory muscles.

Clinical Relevance

Nursing practice connection: Use the key finding related to Side effects of radiation therapy for head and neck cancer to guide bedside assessment, documentation, and the next nursing action.
Nurses play a vital role in assessing, preventing, and managing the oral complications of radiation therapy to improve patient comfort, ensure adequate nutrition, and maintain treatment adherence.
Proactive patient education on oral care, diet, and exercises is a key nursing responsibility before and during treatment.
What if? If a patient develops Grade 3 mucositis (severe pain, unable to eat solid food), the nurse must escalate care. This includes collaborating with the oncologist for aggressive pain management (possibly opioids), consulting a dietitian for liquid nutrition or feeding tube consideration, and ensuring meticulous oral hygiene to prevent secondary infections.

How to Approach the Question

First, recognize this is a negative-format question because of the word 'except'. This means you are looking for the option that does not belong.
Identify the core subject of the question: expected side effects of radiation therapy for oral cancer.
Evaluate each option against this core subject.
Option A, Mucositis: Is this a side effect of oral radiation? Yes, it's a classic one.
Option B, Xerostomia: Is this a side effect of oral radiation? Yes, very common.
Option C, Trismus: Is this a side effect of oral radiation? Yes, it's a known late effect.
