1. Dental hygienists are in a key position to assess and detect signs and symptoms of systemic disease because more than one third of the patients treated in a dental office frequently do not interact with a general health care provider.

A. Both the statement and the reason are correct and related
B. Both the statement and the reason are correct but are not related
C. The statement is correct, but the reason is not correct
D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: Dental hygienists often see patients more regularly than general healthcare providers, allowing them to identify systemic issues early.

2. Which of the following statements is correct about MyPlate?

A. Canned fruit can be considered part of the fruit group
B. Soymilk is considered part of the dairy group
C. Beans and peas are considered part of both the protein group and the vegetable group
D. Cream cheese and butter are not part of the dairy group

Correct answer: C

Rationale: According to the MyPlate guide, beans and peas are classified as part of both the protein and vegetable groups due to their high protein content and the nutrients they share with vegetables. This makes Choice C correct. Choice A is incorrect as canned fruit can be part of the fruit group if it's canned in water or 100% fruit juice. Soymilk is considered part of the dairy group, making Choice B incorrect. While cream cheese and butter are dairy products, they are not part of the dairy group on MyPlate because they contain little to no calcium, making Choice D incorrect.

3. Which of the following is reflected in an ECG due to hypokalemia?

A. Tall T waves and Pathologic Q wave
B. Widening QRS Complex and U wave
C. None of the above
D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

4. Which term is used to describe populations located in lower income, inner city, and rural areas with few supermarkets but numerous small stores stocking limited nutritious food items?

A. Food fad
B. Food insecurity
C. Food desert
D. Food patterns

Correct answer: C

Rationale: A food desert refers to areas with limited access to affordable and nutritious food, often found in lower-income urban and rural areas.

5. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:

A. 140 mm Hg and 90 mm Hg, respectively
B. 150 mm Hg and 80 mm Hg, respectively
C. 160 mm Hg and 110 mm Hg, respectively
D. 180 mm Hg and 120 mm Hg, respectively

Correct answer: A

Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.
