1. Which lipid contains 3 fatty acids?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: D

Rationale: The correct answer is 'D. triglyceride.' Triglycerides are composed of one glycerol molecule and three fatty acids, making them the primary form of stored fat in the body. Cholesterol (A) is a different type of lipid, phospholipids (B) have two fatty acids, and 'saturated' (C) refers to the structure of fatty acids, not a specific lipid containing 3 fatty acids.

2. In a patient with chronic kidney disease, which dietary modification is recommended?

• A. Increase protein intake
• B. Reduce potassium intake
• C. Increase sodium intake
• D. Reduce fiber intake

Correct answer: B

Rationale: Reducing potassium intake is important for patients with chronic kidney disease to prevent hyperkalemia.

3. All of the following are instructions for proper foot care to be given to a client with peripheral vascular disease caused by diabetes. Which one is not?

• A. Trim nails using a nail clipper
• B. Apply cornstarch to the foot
• C. Always check the temperature of the water before bathing
• D. Use canvas shoes

Correct answer: A

Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.

4. Which of the following provides the least amount of potassium?

• A. broccoli
• B. potatoes
• C. bananas
• D. cheese

Correct answer: D

Rationale: Cheese provides less potassium compared to broccoli, potatoes, and bananas, which are all rich in this essential mineral.

5. What instruction should a nurse include when teaching a client who has recently been prescribed a low-sodium diet?

• A. Avoid foods such as smoked meats and frozen dinners.
• B. Select foods with less than 4g of sodium as indicated on food labels.
• C. Use soy sauce for flavoring foods instead of table salt.
• D. Processed and prepared foods are typically low in sodium.

Correct answer: A

Rationale: The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.
