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. 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.

3. What type of drug is lamivudine, used for the management of HIV infection?

• A. CCR5 antagonist
• B. fusion inhibitor
• C. nucleoside reverse transcriptase inhibitor
• D. protease inhibitor

Correct answer: C

Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.

4. Chest x-ray was ordered after thoracentesis. When your client asks what is the reason for another chest x-ray, you will explain:

• A. to rule out pneumothorax
• B. to rule out any possible perforation
• C. to decongest
• D. to rule out any foreign body

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. Low levels of physical activity are more commonly associated with which type of cancer?

• A. Esophageal cancer
• B. Pancreatic cancer
• C. Lung cancer
• D. Colon cancer

Correct answer: D

Rationale: Low physical activity is most strongly associated with an increased risk of colon cancer. Regular exercise helps regulate bowel movements and reduce inflammation, which are factors that can contribute to the development of colon cancer. Esophageal cancer, pancreatic cancer, and lung cancer are not as directly linked to low levels of physical activity.
