1. Worldwide, what is the most common nutrient deficiency?
- A. magnesium deficiency
- B. iron deficiency
- C. selenium deficiency
- D. zinc deficiency
Correct answer: B
Rationale: Iron deficiency is the most common nutrient deficiency globally. It leads to anemia and affects many populations, especially women and children. Magnesium, selenium, and zinc deficiencies are important, but they are not as prevalent as iron deficiency on a global scale.
2. Which of the following is a normal change observed in an elderly individual?
- A. Enhanced sense of taste
- B. Increased appetite
- C. Frequent urination
- D. Lens thinning
Correct answer: C
Rationale: The correct answer is C, frequent urination. As people age, they may experience physiological changes that can lead to an increased frequency of urination. This is due to a decrease in bladder capacity and increased bladder irritability, which are normal age-related changes. On the contrary, the sense of taste (Choice A) and appetite (Choice B) often decrease with age, not increase. As for Choice D, the lens of the eye actually thickens with age, not thins, leading to conditions like presbyopia. Therefore, Choices A, B, and D are incorrect.

- A. Immediately applying a chemical decontamination foam to the area of contamination
- B. Thoroughly washing and rinsing the patient with soap and water

Correct answer: D
Rationale: The correct first step in decontamination is to remove the patient's clothing and jewelry to prevent further exposure and then rinse the patient with water. This helps to eliminate any contaminants on the patient's body. Choice A is incorrect because applying a chemical decontamination foam should come after removing clothing. Choice B is incorrect as washing and rinsing the patient should follow the removal of clothing. Choice C is incorrect as personal protective equipment should be worn by the individual performing the decontamination, not applied to the patient.

Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration.

Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.
