Which of the following is NOT a feature of a healthy mouth?

Appeared in: AIIMS BBSR SNO - 2019

Explanation

Dry and rough lips are an abnormal finding and not a feature of a healthy mouth.
This condition often indicates systemic issues such as dehydration, vitamin deficiencies, or can be a side effect of certain medications.
Healthy lips, as confirmed by assessment guidelines, should be moist, pink, smooth, and symmetrical.

Option B: This is a hallmark feature of a healthy oral cavity. The mucous membranes should be pink and well-hydrated.
Option C: This indicates good oral hygiene and the absence of dental plaque and caries, which is a sign of a healthy mouth.
Option D: Sufficient saliva is crucial for cleansing the mouth, moistening food, and protecting against bacteria. It is a key component of oral health.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Assessment of Oral Health as background academic context rather than a clinical decision trigger.
Oral assessment is a fundamental nursing task that can reveal signs of systemic diseases, nutritional deficiencies, and dehydration.
Nurses play a vital role in providing oral care, especially for dependent patients (e.g., unconscious, elderly, or critically ill), to prevent complications like aspiration pneumonia and oral infections (stomatitis).
What if? If a patient on diuretics reports a dry mouth, the nurse should assess for other signs of dehydration (e.g., poor skin turgor, low urine output), review fluid intake, and provide frequent oral hygiene, as the diuretic is likely contributing to the dryness.

How to Approach the Question

First, identify the negative framing of the question with the keyword 'NOT'. This means you are looking for the option that is an outlier or incorrect statement.
Recall the standard characteristics of a healthy mouth.
Evaluate each option against these characteristics.
Option A (Dry and rough lips) is a sign of a problem, not health.
Options B, C, and D (Pink/moist mouth, clean teeth, adequate saliva) are all positive signs of oral health.
Conclude that 'Dry and rough lips' is the feature that is NOT indicative of a healthy mouth.
