Nursing Elites

1. _____ 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.

2. Can a person with Celiac disease eat Poptarts that contain gluten?

• A. Yes
• B. No
• C. Only in small quantities
• D. Only if they are gluten-free Poptarts

Correct answer: B

Rationale: A person with Celiac disease cannot consume Poptarts that contain gluten because gluten is a protein found in wheat, barley, and rye, triggering an autoimmune response in individuals with Celiac disease and damaging their small intestine. Even small quantities of gluten can lead to this harmful response, making choices 'A' and 'C' incorrect. While gluten-free Poptarts may be suitable for individuals with Celiac disease, regular Poptarts containing gluten are not safe for consumption by them, rendering choice 'D' incorrect as well.

3. What food is most likely a source of trans fats in the diet?

• A. red meat
• B. peanut oil
• C. corn chips
• D. salmon

Correct answer: C

Rationale: The correct answer is C: corn chips. Corn chips, especially those processed and fried, are a common source of trans fats, which are associated with an increased risk of heart disease. Red meat (choice A) and salmon (choice D) do not typically contain trans fats unless they are processed or cooked in trans fat-containing oils. Peanut oil (choice B) can be a healthier option compared to trans fat-containing oils.

4. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

• A. reducing cholesterol synthesis
• B. suppressing inflammation
• C. reducing blood clotting
• D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

5. The mentally ill person responds positively to the nurse who is warm and caring. This is a demonstration of the nurse’s role as:

• A. counselor
• B. mother surrogate
• C. therapist
• D. socializing agent

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.
