Nursing Elites

1. What are the potential consequences of damage to the stomach?

• A. Reduced digestion of carbohydrates
• B. Inability to produce or secrete bile
• C. Inability to produce or secrete gastric acid
• D. Increased ability to produce or secrete intrinsic factor

Correct answer: C

Rationale: Damage to the stomach can lead to a reduced ability to produce gastric acid (Choice C) and intrinsic factor, the latter of which is crucial for vitamin B12 absorption (Choice D). That's why these two choices are correct. The stomach doesn't play a direct role in the digestion of carbohydrates (Choice A) as this process primarily occurs in the small intestine with the help of pancreatic enzymes. Similarly, bile is produced by the liver and stored in the gallbladder, not the stomach, hence stomach damage wouldn't lead to an inability to produce or secrete bile (Choice B).

2. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?

• A. No—absorbed compounds show up in urine, not feces
• B. Yes—absorbed compounds show up in feces, not urine
• C.
• D.

Correct answer: A

Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.

3. You will give health instructions to Carlo, a case of bronchial asthma. The health instruction will include the following, EXCEPT:

• A. Avoid emotional stress and extreme temperature
• B. Avoid pollution like smoking
• C. Avoid pollens, dust, seafood
• D. Practice respiratory isolation

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. A nurse is completing an admission assessment on an adolescent client who is a vegetarian. He eats milk products but does not like beans. Which of the following items should the nurse suggest the client order for lunch to provide the nutrients most likely to be lacking in his diet?

• A. Peanut butter and jelly sandwich
• B. Baked potato topped with sour cream
• C. Bagel with cream cheese
• D. Fruit salad

Correct answer: D

Rationale: The correct answer is 'Fruit salad.' Since the adolescent client is a vegetarian who eats milk products but does not like beans, suggesting a fruit salad for lunch would provide essential nutrients like vitamins, minerals, and fiber that are commonly found in fruits. Fruit salad can help supplement the nutrients that may be lacking in his diet. Choices A, B, and C do not offer the same variety and quantity of nutrients as a fruit salad, making them less optimal choices for meeting the client's dietary needs.

5. _____ 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.
