1. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

A. Thiamine (B1)
B. Riboflavin (B2)
C. Niacin (B3)
D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

2. Each statement is true, except one. Which is the exception?

A. Infant formulas should be discontinued at approximately 1 year of age
B. Low-fat milk is not recommended for children younger than 2 years
C. Special toddler formulas are available but are unnecessary
D. Vitamin D-fortified whole milk should not be provided until 2 years

Correct answer: D

Rationale: The correct answer is D. Vitamin D-fortified whole milk should be provided starting at age 1 after discontinuing breast feeding or infant formulas, not at 2 years. Providing whole milk at age 2 is appropriate. Choices A, B, and C are correct statements: infant formulas are typically discontinued around 1 year of age, low-fat milk is not recommended for children under 2 years, and special toddler formulas are unnecessary.

3. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:

A. 140 mm Hg and 90 mm Hg, respectively
B. 150 mm Hg and 80 mm Hg, respectively
C. 160 mm Hg and 110 mm Hg, respectively
D. 180 mm Hg and 120 mm Hg, respectively

Correct answer: A

Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.

4. Which of the following has the greatest effect on an increase in body weight?

A. Carbohydrate intake
B. Protein intake
C. Fat intake
D. Total kilocalories

Correct answer: D

Rationale: Total kilocalories have the greatest effect on body weight as they represent the overall energy intake from all macronutrients combined. While the consumption of specific macronutrients like carbohydrates, proteins, and fats can affect weight management, the total calories consumed play the most significant role in determining body weight. Therefore, choices A, B, and C are incorrect as they focus on individual macronutrients rather than the overall energy balance provided by total kilocalories.

5. A nurse is caring for a client who is well-hydrated and who demonstrates no evidence of anemia. Which of the following laboratory values gives the nurse an assessment of the adequacy of the client's protein uptake and synthesis?

A. Albumin
B. Calcium
C. Sodium
D. Potassium

Correct answer: A

Rationale: The correct answer is Albumin. Albumin is a protein made by the liver and is a key indicator of the body's protein status. Low levels of albumin can indicate inadequate protein intake or synthesis. Choices B, C, and D (Calcium, Sodium, and Potassium) are not direct indicators of protein uptake and synthesis. Calcium is related to bone health, Sodium to fluid balance, and Potassium to nerve and muscle function.
