1. Based on universally-accepted color codes, what color would you expect a tank containing nitrous oxide (laughing gas) to have?

• A. Red
• B. Blue
• C. Green
• D. Orange

Correct answer: A

Rationale: The correct answer is A: Red. In the medical field, tanks containing nitrous oxide (laughing gas) are typically color-coded with a specific color for easy identification. Nitrous oxide tanks are commonly labeled with a red color code. This color-coding system helps healthcare providers quickly and accurately identify the contents of the tanks, reducing the risk of errors in administering gases to patients. Choices B, C, and D are incorrect because the universally-accepted color for nitrous oxide tanks is red, not blue, green, or orange.

2. A client is being instructed by a nurse about foods that should be included in a low-fiber diet. Which statement by the client indicates understanding?

• A. I can cut up carrots and celery sticks for my lunch.
• B. I will eat a bran muffin for my mid-morning snack.
• C. I will have oatmeal with skim milk for my breakfast.
• D. I should choose canned peaches for my fruit serving.

Correct answer: D

Rationale: The correct answer is D because canned peaches are lower in fiber compared to the other options. Carrots, celery sticks, bran muffins, and oatmeal are high-fiber choices, which are not suitable for a low-fiber diet. Choosing canned peaches aligns with the requirements of a low-fiber diet.

3. Does taste perception decline with age, and are individuals taking three or more medications likely to have less taste sensitivity, requiring greater amounts of sodium and sugar to perceive these tastes?

• 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: A

Rationale: Both statements are indeed true. As people age, their taste perception tends to decline. This change can be further exacerbated by the use of multiple medications, which can potentially dull taste sensitivity even more. Consequently, these individuals often need to consume foods with higher levels of sodium and sugar in order to perceive these tastes. Choices B, C, and D are incorrect because they deny either one or both of these established facts.

4. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.

• A. glucose
• B. monosaccharides
• C. galactose
• D. disaccharides

Correct answer: B

Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.

5. What level of sodium restriction would be included as part of nutrition therapy for heart failure?

• A. Less than 500 mg per day
• B. 1000 mg to 1500 mg per day
• C. 1500 mg to 3000 mg per day
• D. 3000 to 3500 mg per day

Correct answer: C

Rationale: The correct answer is 1500 mg to 3000 mg per day. This is the level of sodium restriction typically recommended for heart failure patients. It helps manage fluid retention and reduce blood pressure, which are both crucial in treating heart failure. A sodium intake of less than 500 mg per day (Choice A) might be too restrictive and is not typically recommended. Similarly, an intake of 1000 mg to 1500 mg per day (Choice B) falls short of the recommended range. Lastly, an intake of 3000 to 3500 mg per day (Choice D) exceeds the recommended upper limit, potentially exacerbating fluid retention and high blood pressure.
