1. How long can Vitamin A be stored in the liver for at least?

A. 1 month.
B. 6 months.
C. 1 year.
D. 18 months.

Correct answer: C

Rationale: Vitamin A can be stored in the liver to meet basic needs for at least 1 year. This storage capacity allows the body to have a reserve of Vitamin A to sustain its needs over an extended period. Choices A, B, and D are incorrect because they underestimate the storage capacity of Vitamin A in the liver, which can last longer than these durations.

2. Which of the following is not a desirable blood lipid value?

A. low total cholesterol
B. high LDL
C. high HDL
D. low blood triglycerides

Correct answer: B

Rationale: The correct answer is B. High levels of LDL (low-density lipoprotein) cholesterol are undesirable as they are associated with an increased risk of cardiovascular disease. Therefore, low total cholesterol (choice A), high HDL (choice C), and low blood triglycerides (choice D) are considered desirable blood lipid values. Low total cholesterol is beneficial as high levels can increase the risk of heart disease. High HDL cholesterol is considered good as it helps remove LDL cholesterol from the arteries. Low blood triglycerides are also preferred as high levels are associated with an increased risk of heart disease.

3. All of the following are seen in a child with measles. Which one is not?

A. Reddened eyes
B. Coryza
C. Pustule

Rationale: Measles typically presents with symptoms like reddened eyes, coryza (inflammation of the mucous membrane in the nose), and cough. However, pustules are not a common symptom of measles. Pustules are more characteristic of conditions like chickenpox rather than measles. Understanding these distinctions is crucial for accurate diagnosis and appropriate treatment.
