1. Which vitamin is crucial for collagen synthesis and wound healing?

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

Correct answer: A

Rationale: The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.

2. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

3. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?

• A. X-ray
• B. Observation of gastric aspirate
• C. Testing of pH of gastric aspirate
• D. Placement of external end of tube under water

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.

4. What is a disadvantage of using a food frequency questionnaire?

• A. It does not influence the food choices of the consumer
• B. It is not affected by seasonal changes in the diet
• C. It is not effective for monitoring short-term changes in food intake
• D. It does not take too long to obtain the results

Correct answer: C

Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.

5. Substance abuse is different from substance dependence in that, substance dependence:

• A. includes characteristics of adverse consequences and repeated use
• B. requires long term treatment in a hospital based program
• C. produces less severe symptoms than that of abuse
• D. includes characteristics of tolerance and withdrawal

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
