1. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

2. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.

3. Which foods are the biggest contributors of saturated fats consumed by Americans?

• A. Butter, coconut, and palm oils
• B. Corn oil
• C. Meat and milk
• D. Cheese, pizza, desserts, and chicken

Correct answer: D

Rationale: The correct answer is D: Cheese, pizza, desserts, and chicken. These foods are significant contributors to the intake of saturated fats in the American diet, often found in processed and fast foods. Choices A, B, and C are incorrect because while butter, coconut, and palm oils (A) are sources of saturated fats, they are not the biggest contributors in the American diet. Corn oil (B) is a source of unsaturated fats, and meat and milk (C) contain saturated fats but are not the primary contributors compared to cheese, pizza, desserts, and chicken.

4. A client with gastroesophageal reflux disease is being taught by a nurse about managing the illness. Which of the following recommendations should the nurse include in the teaching?

• A. Limit fluid intake not related to meals.
• B. Chew on mint leaves to relieve indigestion.
• C. Avoid eating within 3 hours of bedtime.
• D. Season foods with black pepper.

Correct answer: C

Rationale: The correct recommendation for managing gastroesophageal reflux disease is to avoid eating within 3 hours of bedtime. This helps prevent acid reflux by allowing food to digest before lying down. Choices A, B, and D are incorrect. Limiting fluid intake not related to meals is not a standard recommendation for managing GERD. Chewing on mint leaves may worsen symptoms as mint can relax the lower esophageal sphincter, allowing stomach acid to flow back up. Seasoning foods with black pepper does not specifically help manage GERD.

5. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

• 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: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.
