1. Health practitioners evaluate disease progression in HIV-infected patients by measuring the concentrations of helper T cells and circulating virus, called _____.

• A. cross resistance
• B. the immune response
• C. acquired resistance
• D. the viral load

Correct answer: D

Rationale: The viral load is the measure of the amount of circulating virus in the blood and is used to evaluate the progression of HIV infection.

2. A nurse is developing an education program for a community group about dietary intake of vitamins and minerals in the diet. The nurse should include which of the following foods as sources of vitamin C? (Select the food that does not apply.)

• A. Green pepper
• B. Orange
• C. Cabbage
• D. Milk

Correct answer: D

Rationale: The correct answer is E: Milk. Milk is not a significant source of vitamin C. Choices A, B, C, and D are all good sources of vitamin C. Green pepper, orange, cabbage, and strawberries contain vitamin C and can be included in the diet to meet the body's need for this essential vitamin. Milk, on the other hand, is not known for its vitamin C content, so it does not apply as a source of this particular vitamin.

3. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.

4. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?

• 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. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.

5. How is an ear infection that persists for less than 14 days classified?

• A. Mastoiditis
• B. Chronic Ear Infection
• C. Acute Ear Infection
• D. Otitis Media

Correct answer: C

Rationale: Acute Ear Infection is the correct answer because it typically refers to an infection that is short-lived and often severe, typically lasting less than 14 days. Chronic Ear Infection (Choice B) is incorrect as it refers to an ear infection that lasts for a long time or recurs often, typically more than three months. Mastoiditis (Choice A) is a complication of a middle ear infection and not an ear infection itself. Otitis Media (Choice D) is a general term for inflammation or infection in the middle ear, which can be either acute or chronic, so it's not specific enough to be the correct answer. Understanding the duration and severity of symptoms can help in identifying the type of ear infection, facilitating appropriate treatment and prevention of complications.
