1. 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.

2. People with only one arm or hand may benefit from using a ____ when eating?

• A. dish with suction cups
• B. rocker knife
• C. utensil holder
• D. flexible straw

Correct answer: B

Rationale: A rocker knife is specifically designed for individuals with limited use of one hand or arm, allowing them to cut food easily. This makes it a suitable option for people with only one arm or hand. Choice A, a dish with suction cups, may not directly aid in cutting food with one hand. Choice C, an utensil holder, is not typically used for cutting food. Choice D, a flexible straw, is more related to drinking liquids and not specifically designed to assist in cutting food one-handed.

3. Which of the following conditions is not caused by energy drinks?

• A. Nervousness
• B. Bradycardia
• C. Seizures
• D. Dental caries

Correct answer: B

Rationale: Energy drinks are known for causing a variety of health issues, including nervousness, seizures, and an increased risk of dental caries due to their high sugar content. However, they do not cause bradycardia, which is a slow heart rate. Instead, energy drinks are associated with causing an increased or rapid heart rate, known as tachycardia. Therefore, out of the listed options, bradycardia is the condition not caused by energy drinks.

4. A pregnant woman has applied to use WIC services to supplement her food intake. The WIC program would provide vouchers for _____ in this situation.

• A. lean beef
• B. fruit-flavored yogurt
• C. whole grain bread
• D. refried beans

Correct answer: C

Rationale: The correct answer is C: whole grain bread. The WIC program aims to provide nutritious foods to support a healthy diet during pregnancy. Whole grain bread is a good source of fiber and essential nutrients. Choice A, lean beef, is a protein source but may not be as versatile as whole grain bread in providing a variety of nutrients essential during pregnancy. Choice B, fruit-flavored yogurt, may contain added sugars and may not offer the same level of essential nutrients as whole grain bread. Choice D, refried beans, is a good source of protein and fiber, but whole grain bread is often a staple recommended in pregnancy for its nutritional benefits.

5. What is the term for a state of disequilibrium wherein a person cannot readily solve a problem or situation using their usual coping mechanisms?

• A. Crisis
• B. Mental health
• C. Mental illness
• D. Stress

Correct answer: A

Rationale: In psychological terms, a 'Crisis' refers to a state of disequilibrium wherein a person cannot readily solve a problem or situation even by using his usual coping mechanisms. This is different from 'Mental Illness' (Choice C) which is a more general term for a wide range of mental health conditions that affect mood, thinking and behavior. 'Mental Health' (Choice B) is a state of well-being in which an individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community. Finally, 'Stress' (Choice D) is a state of mental or emotional strain or tension resulting from adverse or demanding circumstances, but it does not necessarily disrupt equilibrium to the extent that usual coping mechanisms are ineffective, unlike 'Crisis'.
