A nurse prepares an educational session on the importance of oral hygiene. Which teaching tip should be included in the section about preventing gingivitis?

A firm toothbrush is most effective in plaque removal.

Brushing more than twice per day irritates the gums.

Ensure that dental restorations fit well.

Avoid flossing if there is bleeding at the gumline.

Answer and Explanation

The Correct Answer is C

Choice a reason:
A firm toothbrush is not recommended for plaque removal as it can damage the gums and tooth enamel. Soft-bristled toothbrushes are preferred because they are effective at removing plaque while being gentle on the gums and enamel.

Choice b reason:
Brushing more than twice per day does not necessarily irritate the gums unless done with improper technique or with a hard-bristled toothbrush. It is important to brush gently with a soft-bristled toothbrush and to use fluoride toothpaste to maintain oral hygiene and prevent gingivitis.

Choice c reason:
Ensuring that dental restorations such as fillings and crowns fit well is crucial in preventing gingivitis. Poorly fitted restorations can trap food particles and bacteria, leading to plaque buildup and gum inflammation. Regular dental check-ups can help ensure that restorations remain intact and do not contribute to gingivitis.

Choice d reason:
Flossing should not be avoided even if there is bleeding at the gumline. Bleeding can be a sign of gingivitis, and flossing can help remove the plaque and bacteria causing the inflammation. If bleeding persists, it is important to consult a dentist.

Correct Answer is C

Explanation

Choice A Reason:
The facial nerve, or cranial nerve VII, is responsible for the taste sensation in the anterior two-thirds of the tongue, not the posterior third. It carries taste sensations from the front part of the tongue via the chorda tympani branch.

Choice B Reason:
The abducens nerve, or cranial nerve VI, has no role in taste sensation. It is primarily involved in controlling the lateral rectus muscle of the eye, which abducts the eye.

Choice C Reason:
The glossopharyngeal nerve, or cranial nerve IX, provides special sensory innervation for taste to the posterior third of the tongue. This enables the sensation of various tastes like salty, sweet, sour, and bitter in this region.

Choice D Reason:
The hypoglossal nerve, or cranial nerve XII, is responsible for motor control of the tongue muscles but does not provide sensory innervation for taste.

A. Objective Data B. Introspective Data C. Subjective Data D. Reflective Data

Correct Answer is C

Explanation

Choice a reason:
Objective data refers to information that is observable and measurable by the healthcare provider, such as vital signs, physical examination findings, and laboratory results. The patient's statements about his feelings are not objective data because they cannot be directly measured or observed by the nurse.

Choice b reason:
Introspective data is not a commonly used term in healthcare. Introspection generally refers to the examination of one's own conscious thoughts and feelings, which in the context of healthcare, can be part of subjective data as it is reported by the patient.

Choice c reason:
Subjective data consists of information that is reported by the patient, including feelings, perceptions, and concerns. It is called 'subjective' because it is based on the patient's personal experience and cannot be independently verified by the nurse. In this case, the patient's report of feeling anxious, nauseated, and hot is considered subjective data.

Choice d reason:
Reflective data is not a standard term in healthcare documentation. Reflection is a process of personal thought and does not pertain to the clinical data gathered during a patient assessment.
