1. A dental hygienist finds several new carious lesions in a patient with chronic obstructive respiratory disease (COPD). While conducting the medical and dental histories, the dental hygienist is most likely to find an increased use of which of the following?

• A. Protein
• B. Cough drops
• C. Fluoride
• D. Xylitol

Correct answer: B

Rationale: The correct answer is B: Cough drops. Patients with COPD often use cough drops to manage their symptoms, which can lead to an increase in carious lesions due to their sugar content. Choices A, C, and D are incorrect as protein, fluoride, and xylitol are not typically associated with an increased risk of carious lesions in patients with COPD.

2. How many words does a typical 12-month-old infant use?

• A. About 12 words
• B. Twenty or more words
• C. About 50 words
• D. Two, plus 'mama' and 'papa'

Correct answer: D

Rationale: A typical 12-month-old infant typically uses very few words, with 'mama' and 'papa' being common early words. At this age, most infants are still in the early stages of language development, and their vocabulary is limited. Choices A, B, and C suggest higher word counts which are not typical for infants at this age.

3. Overdosage of medication or anesthetic can happen even with the aid of technology like infusion pumps, sphygmomanometer, and similar devices/machines. As a staff member, how can you improve the safety of using infusion pumps?

• A. Check the functionality of the pump before use
• B. Select the brand of infusion pump carefully
• C. Allow the technician to set the infusion pump before use
• D. Verify the flow rate against your calculation

Correct answer: D

Rationale: To enhance the safety of using infusion pumps, it is crucial to verify the flow rate against your calculation. This step ensures that the prescribed dosage is being delivered accurately, reducing the risk of medication errors. Checking the functionality of the pump before use (Choice A) is also important to ensure it is working properly. Allowing the technician to set the pump (Choice C) may not always guarantee the correct settings. Selecting the brand of infusion pump carefully (Choice B) is not directly related to the safe use of the pump.

4. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

5. Begins carb digestion in the mouth:

• A. pepsin
• B. salivary amylase
• C. CCK
• D. secretin

Correct answer: B

Rationale: Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth by breaking down starches into simpler sugars.
