Nursing Elites

1. Which vitamin is also known as Niacin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

2. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

3. The ideal time to begin taking folate to prevent neural tube defects is:

• A. Before conception
• B. Once pregnancy begins
• C. At 6 weeks
• D. Upon completion of the first trimester

Correct answer: A

Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.

4. A client is prescribed a 1500-calorie diet. Thirty percent of the calories are to be derived from fat. How many grams of fat should the nurse tell the client to consume per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 21
• B. 49
• C. 60
• D. 50

Correct answer: D

Rationale: To calculate the grams of fat, first, determine the calories from fat by multiplying the total calorie intake (1500 calories) by the percentage of calories from fat (30%), which equals 450 calories from fat. Since 1 gram of fat is equivalent to 9 calories, divide the total calories from fat (450) by the calories in 1 gram of fat (9) to get the answer in grams, which is 50. Therefore, the client should consume 50 grams of fat per day. Choice A (21), Choice B (49), and Choice C (60) are incorrect as they do not reflect the accurate calculation based on the given information.

5. Discharge plans of diabetic clients include injection site rotation. You should emphasize that the space between sites should be:

• A. 6.0 cm.
• B. 5.0 cm.
• C. 2.5 cm.
• D. 4.0 cm.

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
