1. Which nutrient is most important for maintaining fluid balance in the body?

Correct answer: B

Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.

2. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

Correct answer: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

3. What is the most appropriate nutritional advice for a patient with hypertension?

Correct answer: C

Rationale: Increasing potassium intake can help manage blood pressure levels in patients with hypertension.

4. What is the most effective way to limit the number of microorganisms in the hospital?

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.

5. Characteristics of type two diabetes include all of the following except:

Correct answer: D

Rationale: Type 2 diabetes is characterized by insulin resistance, high blood glucose levels, and high blood insulin levels. Rapid destruction of the pancreas is not a feature of this condition. The destruction of pancreatic beta cells is more commonly associated with type 1 diabetes, not type 2 diabetes. Therefore, option D is the correct answer. Options A, B, and C are all characteristic features of type 2 diabetes, making them incorrect choices.
