Question 1

All of the following conditions would contraindicate administration of nitrous oxide EXCEPT one.Which one is the EXCEPTION?&#10;A) Emphysema&#10;B) Chronic obstructive pulmonary disease&#10;C) Pneumonia&#10;D) Asthma

Accepted Answer

Asthma is not a contraindication for nitrous oxide administration; in fact, nitrous oxide can be safely used in asthmatic patients as it can help in reducing anxiety and potentially improve bronchodilation. Conditions like emphysema, chronic obstructive pulmonary disease (COPD), and pneumonia involve compromised lung function, making the administration of nitrous oxide potentially dangerous due to the risk of worsening respiratory distress or failure.

Question 2

Respiratory diseases that last for less than 3 weeks are considered&#10;A) Chronic&#10;B) Temporary&#10;C) Acute&#10;D) Recurrent

Accepted Answer

Respiratory diseases that last for less than 3 weeks are considered acute. Acute diseases have a rapid onset and short duration, typically less than 3 months. Chronic diseases, on the other hand, last for a prolonged period, typically more than 3 months, and can be managed but not cured.

Question 3

Intrinsic asthma is the most common form of adult asthma.Common allergens for asthma patients include antibiotics,aspirin,ibuprofen,and other NSAIDs.&#10;A) Both statements are true.&#10;B) Both statements are false.&#10;C) The first statement is true; the second is false.&#10;D) The first statement is false; the second is true.

Accepted Answer

The most common form of adult asthma is actually extrinsic asthma, which is triggered by allergens. The second statement is true because antibiotics, aspirin, ibuprofen, and other NSAIDs can indeed trigger asthma attacks in some individuals.

Question 4

Patients with tuberculosis infection will be asymptomatic.Patients with tuberculosis will present with symptoms.&#10;A) Both statements are true.&#10;B) Both statements are false.&#10;C) The first statement is true; the second is false.&#10;D) The first statement is false; the second is true.

Accepted Answer

Both statements are accurate. Patients with a tuberculosis infection (latent TB) can be asymptomatic, meaning they carry the bacteria but do not show symptoms. On the other hand, patients with active tuberculosis disease will present with symptoms, such as coughing, fever, and weight loss.

Question 5

Health-care providers should be tested annually for tuberculosis.A positive purified protein derivative test indicates active disease and requires treatment.&#10;A) Both statements are true.&#10;B) Both statements are false.&#10;C) The first statement is true; the second is false.&#10;D) The first statement is false; the second is true.

Accepted Answer

The first statement is true as health-care providers are considered to be at high risk for exposure to tuberculosis and hence should be tested annually. However, the second statement is false as a positive purified protein derivative test only indicates the presence of the TB bacteria in the body, but not necessarily active disease. Further tests are needed to confirm active disease and then treatment can be initiated.

Question 6

Which of the following respiratory conditions experienced by a hygienist would necessitate avoidance of patient care?&#10;A) Acute respiratory infection&#10;B) Chronic bronchitis&#10;C) Cystic fibrosis&#10;D) Emphysema&#10;

Accepted Answer

Acute respiratory infection is a contagious condition, and a hygienist with this condition could easily spread the infection to patients. Therefore, a hygienist with acute respiratory infection should avoid patient care until the infection has passed.

Answer: B, C, D 
 Chronic bronchitis, cystic fibrosis, and emphysema are chronic respiratory conditions that could make it difficult for a dental hygienist to perform patient care due to the increased risk of respiratory distress. A hygienist with one of these conditions may need to avoid patient care, or take extra precautions such as wearing a mask or using supplemental oxygen while treating patients.

Question 7

Which of the following protocols would be appropriate for a patient who reports a history of a positive skin test but no active tuberculosis?&#10;A) Physician consult prior to treatment&#10;B) Standard precautions for infection control&#10;C) Multiple antibiotic regimen&#10;D) Referral for a follow-up chest radiograph

Accepted Answer

Standard precautions for infection control are appropriate for a patient with a positive skin test but no active tuberculosis. This includes measures such as using gloves, gowns, and masks when in contact with the patient and ensuring proper ventilation in the patient's room. Antibiotics are not necessary if there is no active tuberculosis, and a physician consult or referral for a follow-up chest radiograph may not be needed if there are no other symptoms or signs of active disease.

Question 8

Patients with respiratory disease should have their partial pressure of oxygen (PO₂)assessed prior to treatment.Patients with a PO₂ of 90% may receive treatment without any modification. A) Both statements are true. B) Both statements are false. C) The first statement is true; the second is false. D) The first statement is false; the second is true.

Accepted Answer

It is true that patients with respiratory disease should have their partial pressure of oxygen assessed prior to treatment. However, the statement that patients with a PO₂ of 90% may receive treatment without any modification is false, as a PO₂ of 90% indicates hypoxemia and may require oxygen therapy or other modifications to treatment.

Question 9

The small air sacs in the lungs where blood is oxygenated are called&#10;A) Bronchi&#10;B) Alveoli&#10;C) Sinuses&#10;D) Lobes

Accepted Answer

The small air sacs in the lungs where blood is oxygenated are called alveoli. Bronchi are large air passages that lead into the lungs. Sinuses are air-filled spaces in the skull connected to the nasal cavity. Lobes are major sections of the lungs.

Question 10

A patient who experiences wheezing three to four times a week and experiences asthmatic attacks a few times a month would be classified as&#10;A) Mild&#10;B) Moderate&#10;C) Severe&#10;D) Chronic

Accepted Answer

The patient's symptoms, including wheezing three to four times a week and a few asthmatic attacks a month, align with mild persistent asthma.

Question 11
