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:
Tachycardia, or an abnormally rapid heart rate, is not a typical finding in myxedema. Myxedema is associated with hypothyroidism, which usually presents with bradycardia, or a slower than normal heart rate, due to the decreased metabolic demands on the body.
Choice B reason:
Diarrhea is not commonly associated with myxedema. Instead, patients with hypothyroidism and myxedema often experience constipation due to slowed gastrointestinal motility.
Choice C reason:
Facial edema, particularly around the eyes, is a classic sign of myxedema. Myxedema is a severe form of hypothyroidism that can cause mucopolysaccharide deposition in the skin, leading to non-pitting edema. This can be particularly noticeable in the face and periorbital area.
Choice D reason:
Heat intolerance is more commonly associated with hyperthyroidism, not hypothyroidism. Patients with myxedema typically have cold intolerance due to a decrease in basal metabolic rate and reduced heat production.

A. Conjunctiva B. Sclera of the eye C. Back of the neck D. Palms of the hands

Correct Answer is B

Explanation

Choice A Reason:
The conjunctiva can sometimes appear yellow in individuals with jaundice; however, it is not the most reliable area to inspect for jaundice. The conjunctiva may be affected by other factors such as environmental irritants or infections, which can alter its appearance.

Choice B Reason:
The sclera of the eye is the most reliable area to inspect for jaundice. The yellowing of the sclera, also known as scleral icterus, is a key indicator of jaundice. The sclera's white background provides a clear contrast, making any yellow discoloration more noticeable. This is particularly true in darker-skinned individuals, where skin changes may be less apparent.

Choice C Reason:
The back of the neck is not a reliable area to inspect for jaundice. Skin pigmentation and lighting can affect the visibility of yellowing, making it an unreliable indicator. Additionally, the back of the neck may have other skin changes unrelated to jaundice that could confuse the assessment.

Choice D Reason:
The palms of the hands are not the most reliable area to inspect for jaundice. While the palms may show yellowing, they are subject to various external factors such as manual labor or exposure to substances that can affect their color. Moreover, the palms' skin may be thicker and less transparent, making subtle changes in color more difficult to detect.
