Explanation

Nutritional deficiencies, especially of Vitamin C and Vitamin K, are a primary systemic cause of gingival bleeding.
Vitamin C is essential for collagen synthesis, which maintains the structural integrity of blood vessels in the gums. Its deficiency (scurvy) leads to fragile capillaries that bleed easily.
Vitamin K is necessary for the synthesis of blood clotting factors. A deficiency can lead to a generalized bleeding tendency, including from the gums.
While plaque-induced gingivitis is the most common cause overall, it is not an option. Among the choices, nutritional deficiency is a classic and fundamental cause tested in nursing exams.

Option A: Removal of plaque is a treatment for gingivitis, the condition that causes bleeding gums. It resolves bleeding, it does not cause it.
Option B: Flossing is a preventative oral hygiene practice. While it can trigger bleeding in gums that are already inflamed due to gingivitis, it is not the underlying cause of the inflammation itself.
Option D: While certain drugs (e.g., anticoagulants, antiplatelets, phenytoin) can cause or worsen gingival bleeding, they are not considered the single 'main' cause compared to the high prevalence of plaque-induced gingivitis or the fundamental role of nutrition in tissue health.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Etiology of Gingival Bleeding as background academic context rather than a clinical decision trigger.
A nurse's assessment of a patient with bleeding gums should always include a dietary history and medication review to identify potential underlying causes like nutritional deficiencies or drug side effects.
Patient education is key. Nurses should teach proper oral hygiene (soft-bristled brush, gentle flossing) and advise on a balanced diet rich in Vitamin C (citrus fruits, berries, leafy greens).
What if? If a patient on anticoagulant therapy reports bleeding gums, the nurse should assess the severity, review recent INR/PT levels, educate on using an extra-soft toothbrush, and notify the primary healthcare provider, as a dose adjustment may be needed.

How to Approach the Question

First, identify the core of the question: it asks for a 'main cause' of gingival bleeding.
Next, evaluate each option's relationship to bleeding gums. 'Removal of plaque' and 'Flossing' are related to oral hygiene practices.
Recognize that plaque removal is a treatment, and flossing is preventative, making them unlikely causes.
Consider the remaining options: 'Nutritional deficiency' and 'Intake of drugs'. Both are valid systemic causes.
Recall classic disease presentations. Vitamin C deficiency (scurvy) is a well-known, fundamental cause of tissue breakdown and bleeding gums, making it a strong candidate for a 'main cause' in an exam context.
Select the option that represents a primary failure in the body's ability to maintain healthy tissue, which is 'Nutritional deficiency'.
