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. A nurse is reinforcing dietary teaching with a client who has vitamin A deficiency. Which of the following food choices should the nurse recommend as the best source of vitamin A?

• A. 1 small baked sweet potato
• B. 1 cup avocado
• C. 1 cup green beans
• D. 1 large apple

Correct answer: A

Rationale: The correct answer is A. Sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for vision and immune function. Avocado (choice B) is a good source of healthy fats but not high in vitamin A. Green beans (choice C) are nutritious but not a significant source of vitamin A. Apples (choice D) are low in vitamin A compared to sweet potatoes.

3. A nurse is providing teaching to a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

• A. Albumin in my urine is an indication of normal kidney function.
• B. I will keep my HbA1c at five percent.
• C. I will have ketones in my urine if my blood glucose is maintained at 190 milligrams per deciliter.
• D. I will keep my blood glucose levels between 200 and 212 milligrams per deciliter.

Correct answer: B

Rationale: The correct answer is B. Maintaining an HbA1c level of 5 percent indicates good long-term blood glucose control and understanding of diabetes management. Choice A is incorrect because the presence of albumin in the urine (albuminuria) is actually an indication of kidney damage in diabetes. Choice C is incorrect as ketones in the urine are a sign of inadequate insulin and can occur when blood glucose levels are high, not at a specific level like 190 mg/dL. Choice D is also incorrect as the client should aim to keep blood glucose levels within a tighter range for better control, typically between 80-130 mg/dL before meals and less than 180 mg/dL after meals.

4. Match protease with its digestive action:

• A. breaks down carbs
• B. breaks down proteins
• C. breaks down lipids
• D. helps fat digestion

Correct answer: B

Rationale: Proteases are enzymes that break down proteins into smaller peptides and amino acids.

5. Mang Carlos has a standing DNR order. He then suddenly stopped breathing and you are at his bedside. You would:

• A. Give extraordinary measures to save Mang Carlos
• B. Stay with Mang Carlos and Do nothing
• C. Call the physician
• D. Activate Code Blue

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.
