1. How many amino acids are essential?

• A. 5
• B. 7
• C. 9
• D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

2. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?

• A. X-ray
• B. Observation of gastric aspirate
• C. Testing of pH of gastric aspirate
• D. Placement of external end of tube under water

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. Each of the following foods has cariostatic properties, with one exception. Which food is the exception?

• A. Eggs
• B. Instant oatmeal
• C. Cheese
• D. Seafood

Correct answer: B

Rationale: Cariostatic foods are those that contribute to the prevention of tooth decay. Eggs, cheese, and seafood are all cariostatic foods, as they can aid in protecting against tooth decay. On the contrary, instant oatmeal does not possess these cariostatic properties. Due to its processed nature, it is more fermentable and cariogenic, which means it can encourage cavity formation. Although it is not directly harmful to the teeth, it does not provide the same defensive benefits against tooth decay as the other choices do. Therefore, 'Instant oatmeal' is the exception among these foods and is the correct answer.

4. Which of the following nutrients deficiency may lead to a diabetes-like condition?

• A. chromium
• B. iron
• C. molybdenum
• D. selenium

Correct answer: A

Rationale: Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.

5. What are symptoms of uncontrolled type 1 diabetes?

• A. Depression, anxiety, and fatigue
• B. Increased thirst, urination, and hunger
• C. Weight gain, macrosomia, and food cravings
• D. Poor wound healing, blurred vision, and recurrent infections

Correct answer: B

Rationale: The correct answer is B: Increased thirst, urination, and hunger. Uncontrolled type 1 diabetes typically presents with classic symptoms including polydipsia (increased thirst), polyuria (frequent urination), and polyphagia (increased hunger). These symptoms are often accompanied by weight loss due to the body's inability to properly utilize glucose for energy. Choices A, C, and D are incorrect as they do not align with the typical symptoms of uncontrolled type 1 diabetes. Depression, anxiety, fatigue, weight gain, macrosomia, food cravings, poor wound healing, blurred vision, and recurrent infections are not primary symptoms associated with uncontrolled type 1 diabetes.
