1. Each of the following describes the physiologic roles of water, except one. Which is the exception?

• A. Acts as a solvent for chemical reactions.
• B. Maintains stability of body fluids.
• C. Enables transport of nutrients and excretion of waste.
• D. Regulates temperature by pooling as perspiration on skin.

Correct answer: D

Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.

2. A healthcare professional is preparing an education program for a group of parents of adolescents. Which of the following should be included as indicators of nutritional risk among adolescents? (Select one that does not apply.)

• A. Skipping more than three meals per week
• B. Eating fast food once weekly
• C. Eating without family supervision frequently
• D. Frequently skipping breakfast

Correct answer: B

Rationale: Among the indicators of nutritional risk among adolescents, skipping meals, eating without family supervision, and frequently skipping breakfast are commonly associated with poor nutrition. However, eating fast food once weekly may not necessarily indicate a significant nutritional risk, as occasional consumption of fast food in moderation is not uncommon among adolescents. This choice is the correct answer because it does not strongly correlate with nutritional risk compared to the other options provided.

3. Which vitamin is primarily obtained from sunlight exposure?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is synthesized in the skin when it is exposed to sunlight. This process allows the body to produce Vitamin D naturally. Vitamin A (Choice A) is found in foods like liver and carrots and is not primarily obtained from sunlight. Vitamin C (Choice B) is commonly found in fruits and vegetables. Vitamin E (Choice D) is present in foods like nuts and seeds and is not primarily obtained from sunlight.

4. All of the following are instructions for proper foot care to be given to a client with peripheral vascular disease caused by diabetes. Which one is not?

• A. Trim nails using a nail clipper
• B. Apply cornstarch to the foot
• C. Always check the temperature of the water before bathing
• D. Use canvas shoes

Correct answer: A

Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.

5. A nurse is caring for a client who has cancer and is receiving total parenteral nutrition (TPN). Which of the following lab values indicates the treatment is effective?

• A. Hct 43%
• B. WBC 8,000/uL
• C. Albumin 4.2 g/dL
• D. Calcium 9.4 mg/dL

Correct answer: C

Rationale: The correct answer is Albumin 4.2 g/dL. Albumin is a protein produced by the liver and is a key indicator of nutritional status. In a client receiving total parenteral nutrition (TPN), an increase in albumin level indicates that the treatment is effective in providing adequate nutrition support. Hct (hematocrit), WBC (white blood cell count), and calcium levels are not direct indicators of the effectiveness of TPN in this context.
