1. What is the term for intestinal wounds associated with Crohn's disease that develop in different areas in the intestine, with normal tissue separating affected regions?

• A. Skip lesions
• B. Fistulas
• C. Fissures
• D. Loop ulcerations

Correct answer: A

Rationale: Skip lesions are typical characteristics of Crohn's disease, where patches of diseased intestine are interspersed with areas of healthy tissue. This is why option A is the correct answer. Option B, fistulas, are abnormal connections between two body parts, which is not what the question is describing. Option C, fissures, are small tears in the lining of the anus, which also do not fit the description in the question. Option D, loop ulcerations, is not a recognized medical term, making it an incorrect choice.

2. What chronic disease has been associated with increased risks of dental problems?

• A. diabetes mellitus
• B. chronic obstructive pulmonary disease
• C. Addison's disease
• D. asthma

Correct answer: A

Rationale: Diabetes mellitus is associated with an increased risk of dental problems, including gum disease and tooth loss, due to high blood sugar levels. While chronic obstructive pulmonary disease (COPD), Addison's disease, and asthma may have oral health implications, diabetes mellitus is specifically known for its strong association with dental issues.

3. Which of the following is a normal change observed in an elderly individual?

• A. Enhanced sense of taste
• B. Increased appetite
• C. Frequent urination
• D. Lens thinning

Correct answer: C

Rationale: The correct answer is C, frequent urination. As people age, they may experience physiological changes that can lead to an increased frequency of urination. This is due to a decrease in bladder capacity and increased bladder irritability, which are normal age-related changes. On the contrary, the sense of taste (Choice A) and appetite (Choice B) often decrease with age, not increase. As for Choice D, the lens of the eye actually thickens with age, not thins, leading to conditions like presbyopia. Therefore, Choices A, B, and D are incorrect.

4. What is the primary function of antioxidants in the diet?

• A. Provide energy
• B. Support muscle growth
• C. Neutralize free radicals
• D. Increase blood sugar

Correct answer: C

Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.

5. What principle is used when the client with fever loses heat through giving cooling bed bath to lower body temperature?

• A. Radiation C. Evaporation
• B. Convection D. Conduction
