1. What type of drug is lamivudine, used for the management of HIV infection?

• A. CCR5 antagonist
• B. fusion inhibitor
• C. nucleoside reverse transcriptase inhibitor
• D. protease inhibitor

Correct answer: C

Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.

2. Age group categories within older adults are classified as 'young old,' 'old,' and 'oldest old,' the latter of which comprises adults aged _____.

• A. 70-80 years
• B. 75-84 years
• C. 80-90 years
• D. 85 years or older

Correct answer: D

Rationale: The 'oldest old' category includes adults aged 85 years or older. This age group faces unique health challenges and requires specialized care. Choices A, B, and C are incorrect as they do not fall within the age range specified for the 'oldest old' category.

3. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

• 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 true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

4. What is the recommended dietary intervention for a patient with hyperlipidemia?

• A. Increase saturated fat intake
• B. Reduce fiber intake
• C. Increase dietary fiber intake
• D. Reduce protein intake

Correct answer: C

Rationale: Increasing dietary fiber can help reduce cholesterol levels in patients with hyperlipidemia.

5. Theresa, a mother with a 2-year-old daughter, asks, 'At what age can I start taking my daughter's blood pressure as a routine procedure, since hypertension is common in our family?' What would your answer be?

• A. At 2 years old, you may
• B. As early as 1 year old
• C. When she's 3 years old
• D. When she's 6 years old

Correct answer: D

Rationale: Regular blood pressure checks generally start from age 3, but in the case of a family history of hypertension, they should start when the child is around 6 years old. This is because the readings will be more reliable and indicative of the child's health condition at this age. The other options are incorrect because they suggest earlier ages for routine blood pressure checks. While blood pressure can be measured at any age, it is not typically included as part of a routine health check-up for very young children unless there are specific health concerns.
