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:
Rhonchi are coarse, rattling respiratory sounds somewhat like snoring, usually caused by obstruction or secretion in the larger airways. They are not considered normal breath sounds and are typically heard in conditions such as chronic bronchitis.

Choice b reason:
Crackles are the sounds you will hear in a lung field that has fluid in the small airways. These sounds are commonly heard in patients with pneumonia, heart failure, and restrictive pulmonary diseases. They are not normal breath sounds.

Choice c reason:
Bronchovesicular sounds are normal breath sounds heard over the main bronchus area and over the upper right posterior lung field. They have a medium pitch and intensity and are heard on both inspiration and expiration. In a healthy individual, these sounds are expected to be heard in the 1st and 2nd intercostal spaces near the sternal body.

Choice d reason:
Tracheal breath sounds are harsh, high-pitched sounds heard when auscultating over the trachea in the neck. They are not normally heard over the intercostal spaces of the chest wall.

A. Resonance B. Tympanic C. Flat D. Dullness

Correct Answer is A

Explanation

Choice a reason:
Resonance is the expected percussion note when percussing over normal, healthy lung tissue. This sound is produced due to the presence of air in the lung parenchyma, which allows for the transmission of sound waves through the air-filled spaces. In a healthy individual, the resonance indicates that the lungs are free from any significant abnormalities that could alter the sound, such as fluid or solid masses.
Choice b reason:
Tympanic notes are typically heard over hollow, air-containing structures like the stomach. This sound is not expected in lung percussion unless there is a large, air-filled cavity within the lung tissue, which would be abnormal and indicative of a pathological condition such as a pneumothorax.
Choice c reason:
A flat percussion note is usually heard over dense tissues where air is not present, such as over the thigh muscles or areas of the chest where lung tissue has been replaced by something more solid, like in the case of a pleural effusion or a lung mass.
Choice d reason:
Dullness on percussion usually indicates that the lung is not air-filled and may be suggestive of underlying conditions such as pneumonia, tumor, or atelectasis. It is a higher-pitched sound compared to flatness and is typically found in areas of the lung that are filled with fluid or solid tissue rather than air.
