1. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

2. Given that orthodontic patients are frequently adolescents, their nutrition and oral self-care are often subpar. A dental hygienist may successfully motivate these noncompliant patients by emphasizing that optimal nutrition and oral self-care can enhance their appearance. Is this true or false?

• 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

Correct answer: A

Rationale: Both statements are indeed true. Many adolescents undergoing orthodontic treatment often neglect proper nutrition and oral hygiene, leading to subpar practices in these areas. It's common for them to be less attentive to these aspects due to various factors. A dental hygienist's role includes motivating these patients towards better self-care practices. One effective approach is by emphasizing that good nutrition and oral hygiene can significantly enhance their appearance. This approach is particularly effective for adolescents as they are often highly conscious about their looks. The other choices are incorrect because they suggest that one or both of the statements are false, which is not the case.

3. What is the conversion of genetic information in RNA into a sequence of amino acids?

• A. translation
• B. transcription
• C.
• D.

Correct answer: A

Rationale: The correct answer is 'translation.' Translation is the process where the genetic information in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a protein. This process occurs at ribosomes within the cell. Option B, 'transcription,' is incorrect as transcription is the process of synthesizing mRNA from a DNA template. Options C and D are irrelevant as they are not related to the conversion of genetic information into amino acids.

4. In PEM, which condition is characterized by symptoms such as muscle weakness, hanging skin, delayed tooth eruption, and changes in saliva?

• A. Marasmus
• B. Kwashiorkor
• C. Anemia
• D. Noma

Correct answer: A

Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.

5. You are to measure the client's initial blood pressure reading by doing all of the following EXCEPT:

• A. Take the blood pressure reading on both arms for comparison
• B. Listen to and identify the phases of Korotkoff sounds
• C. Pump the cuff to around 50 mmHg above the point where the pulse is obliterated
• D. Observe procedures for infection control

Correct answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.
