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

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.

2. Mr. CKK is unconscious and was brought to the E.R. Who among the following can give consent for CKK's operation?

Correct answer: A

Rationale: In the scenario described, when a patient is unconscious and unable to provide consent, the responsibility usually falls on the physician to make decisions regarding the patient's treatment, including obtaining consent for an operation. While nurses play a crucial role in patient care, they typically do not have the authority to provide consent for a major procedure. The next of kin may be consulted for input, but the ultimate decision-making authority lies with the physician. The patient, being unconscious, is unable to provide consent in this situation.

3. In persons who are obese, weight reduction can improve such CHD risk factors as hypertension, blood lipid abnormalities, and?

Correct answer: B

Rationale: Weight reduction in obese individuals can improve insulin resistance, a key factor in reducing the risk of coronary heart disease and type 2 diabetes.

5. After reviewing the health and dental histories, the dental hygienist has adequate information to begin dietary counseling with the patient. Providing a standardized, low-carbohydrate menu is sufficient for most patients with a high caries rate.
