1. Diseases of the heart and blood vessels are collectively referred to as _____.

• A. Coronary artery disease
• B. Cardiovascular disease
• C. Coronary heart disease
• D. Coronary vessel disease

Correct answer: B

Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.

2. Where should a nurse auscultate the apex beat?

• A. At the fifth intercostal space, along the midclavicular line
• B. At the mid-sternum
• C. 2 inches to the left of the lower end of the sternum
• D. 1 inch to the left of the xiphoid process

Correct answer: A

Rationale: The correct location to auscultate the apex beat is at the fifth intercostal space, along the midclavicular line. This is where the apical impulse, also known as the point of maximal impulse (PMI), can be best heard. Choices B, C, and D are incorrect anatomical locations for auscultating the apex beat, which makes them incorrect choices. Auscultating at the correct location allows healthcare providers to assess the heart's function and detect any abnormalities in heart sounds, which is crucial for comprehensive patient care.

3. 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.

• 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: B

Rationale: Both statements are false. Dietary counseling should be personalized, and a standardized low-carbohydrate menu is not sufficient for all patients.

4. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

5. Which of the following provides greater flexibility, better balance, more endurance, and overall better health and greater longevity for older adults?

• A. Eating balanced meals
• B. Not smoking or drinking alcohol
• C. Daily physical activity
• D. Increased intake of calcium and iron

Correct answer: C

Rationale: The correct answer is C: Daily physical activity. Daily physical activity contributes to better flexibility, balance, endurance, and overall health, helping older adults maintain independence and reduce the risk of chronic diseases. Choices A, B, and D, although important for overall health, do not specifically address the benefits of greater flexibility, better balance, more endurance, and greater longevity associated with daily physical activity.
