1. Which chemical structure is represented by glycerol combined with two fatty acids?

• A. Compound lipids
• B. Monoglycerides
• C. Diglycerides
• D. Structural lipids

Correct answer: C

Rationale: The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.

2. Which substance would most likely need to be restricted in patients with heart failure who use diuretics to help reduce fluid retention?

• A. potassium
• B. magnesium
• C. sodium
• D. chloride

Correct answer: C

Rationale: Sodium restriction is crucial in heart failure management to prevent fluid retention, which can worsen symptoms of heart failure.

3. Select all that apply. To lower LDL levels, you should:

• A. consume minimal amounts of hydrogenated and saturated fats
• B. consume more insoluble fibers than soluble fibers
• C. consume alcohol in moderate levels
• D. engage in regular physical activity

Correct answer: A

Rationale: To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.

4. Which topical antimicrobial is most frequently used in burn wound care?

• A. Neosporin
• B. Silver nitrate
• C. Silver sulfadiazine
• D. Sulfamylon

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. A patient tells the nurse “I am depressed to talk to you, leave me alone” Which of the following response by the nurse is most therapeutic?

• C. I’ll seat with you for a moment
• D. Call me when you feel like talking to me

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
