Nursing Elites

1. Larry, 55 years old, who is suspected of having colorectal cancer, is admitted to the CI. After taking the history and vital signs the physician does which test as a screening test for colorectal cancer.

• A. Barium enema
• B. Carcinoembryonic antigen
• C. Annual digital rectal examination
• D. Proctosigmoidoscopy

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

2. Which of the following is not a desirable blood lipid value?

• A. low total cholesterol
• B. high LDL
• C. high HDL
• D. low blood triglycerides

Correct answer: B

Rationale: The correct answer is B. High levels of LDL (low-density lipoprotein) cholesterol are undesirable as they are associated with an increased risk of cardiovascular disease. Therefore, low total cholesterol (choice A), high HDL (choice C), and low blood triglycerides (choice D) are considered desirable blood lipid values. Low total cholesterol is beneficial as high levels can increase the risk of heart disease. High HDL cholesterol is considered good as it helps remove LDL cholesterol from the arteries. Low blood triglycerides are also preferred as high levels are associated with an increased risk of heart disease.

3. Each of the following foods has cariostatic properties, with one exception. Which food is the exception?

• A. Eggs
• B. Instant oatmeal
• C. Cheese
• D. Seafood

Correct answer: B

Rationale: Cariostatic foods are those that contribute to the prevention of tooth decay. Eggs, cheese, and seafood are all cariostatic foods, as they can aid in protecting against tooth decay. On the contrary, instant oatmeal does not possess these cariostatic properties. Due to its processed nature, it is more fermentable and cariogenic, which means it can encourage cavity formation. Although it is not directly harmful to the teeth, it does not provide the same defensive benefits against tooth decay as the other choices do. Therefore, 'Instant oatmeal' is the exception among these foods and is the correct answer.

4. Which food would benefit an anemic patient by increasing their intake?

• A. Beef
• B. Apples
• C. White bread
• D. Fish

Correct answer: A

Rationale: An anemic patient would benefit from increasing their intake of beef. Beef is an excellent source of heme iron, which is critical for treating anemia. Heme iron is absorbed more readily by the body compared to non-heme iron found in plant-based foods. Apples and white bread, while healthy, do not contain significant amounts of heme iron. Fish, although it does contain iron, it's non-heme iron, which is not as efficiently absorbed by the body as heme iron, hence less effective in treating anemia.

5. Fatty acids may differ from one another:

• A. in chain length
• B. in degree of saturation
• C. in number of calories
• D.

Correct answer: D

Rationale: Fatty acids vary in chain length and degree of saturation, affecting their physical properties and health effects.
