1. Which is NOT a characteristic or function of lipids?

A. Involved in energy metabolism and storage
B. Provide insulation and protection
C. Act as hormones that regulate the body
D. Are hydrophilic

Correct answer: D

Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.

2. The mechanism behind most CKD in patients without diabetes is mediated by:

A. enzyme systems
B. immune systems
C. catabolic systems
D. hormonal systems

Correct answer: B

Rationale: In non-diabetic patients, CKD is often mediated by immune system responses. Chronic inflammation triggered by immune system dysfunction can contribute to progressive kidney damage. Therefore, the correct answer is 'immune systems.' Choices A, C, and D are incorrect because CKD in non-diabetic patients is primarily associated with immune system abnormalities rather than enzyme, catabolic, or hormonal systems.

3. How much extra protein (above RDA) is safe to consume?

A. 2x your RDA
B. any amount
C. 3x your RDA
D. 20 grams

Correct answer: A

Rationale: Consuming up to twice the Recommended Dietary Allowance (RDA) of protein is generally considered safe for most people, although it may vary depending on individual health conditions.

4. A patient is being cared for by a nurse who has stomatitis following radiation treatment. Which of the following is an appropriate intervention for the nurse to take?

A. Serve foods without sauces or gravies
B. Offer mouth rinses with normal saline and water
C. Serve foods while still at a hot temperature
D. Instruct the client to drink liquids without a straw

Correct answer: B

Rationale: Offering mouth rinses with normal saline and water is an appropriate intervention for a nurse caring for a patient with stomatitis following radiation treatment. This intervention can help soothe and clean the mouth, promoting comfort and oral hygiene. Choice A is incorrect because serving foods without sauces or gravies does not directly address the client's stomatitis. Choice C is incorrect because serving hot foods can exacerbate discomfort in the client's mouth. Choice D is incorrect because using a straw can help in preventing further irritation in the client's mouth.

5. Which is the best description of a full-liquid diet?

A. Most suitable for individuals with an ileostomy
B. Suitable for individuals with lactose intolerance
C. Contains low saturated fat and high fiber
D. Provides adequate nutrients and is easily digested

Correct answer: D

Rationale: The correct answer is D because a full-liquid diet is designed to provide adequate nutrients while being easily digested. Choices A and B are incorrect because a full-liquid diet is not specifically tailored for individuals with an ileostomy or lactose intolerance. Choice C is also incorrect as it describes characteristics that are not defining features of a full-liquid diet.
