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. Which of the following terms refers to weakness of both legs and the lower part of the trunk?

• A. Paraparesis
• B. Hemiplegia
• C. Quadriparesis
• D. Paraplegia

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.

3. What is the most common type of kidney stone?

• A. Cystine
• B. Calcium
• C. Struvite
• D. Uric acid

Correct answer: B

Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.

4. A client is planning eating strategies with a nurse who has nausea from equilibrium imbalance. Which of the following strategies should the nurse recommend?

• A. Encourage the client to eat, even if nauseated.
• B. Provide low-fat carbohydrates with meals.
• C. Limit fluid intake between meals.
• D. Serve hot foods at mealtime.

Correct answer: B

Rationale: The correct answer is B: Provide low-fat carbohydrates with meals. Low-fat carbohydrates are easier to digest and can help manage nausea without overloading the digestive system. Encouraging the client to eat even if nauseated (Choice A) may worsen their symptoms. Limiting fluid intake between meals (Choice C) may lead to dehydration, which can exacerbate nausea. Serving hot foods at mealtime (Choice D) may not necessarily address the underlying issue of equilibrium imbalance causing nausea.

5. Much of the research investigating probiotics and intestinal illness has focused on the prevention and treatment of _____.

• A. irritable bowel syndrome
• B. Crohn's disease
• C. diverticulitis
• D. infectious diarrhea

Correct answer: D

Rationale: The correct answer is 'D: infectious diarrhea.' Research has extensively explored the use of probiotics in the prevention and treatment of infectious diarrhea. Probiotics can aid in restoring the balance of gut flora, thereby reducing symptoms. Choices A, B, and C are incorrect because while probiotics may have some benefits for these conditions, the primary focus of research in relation to probiotics and intestinal illness has been on infectious diarrhea.
