Nursing Elites

1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. Which symptoms are associated with cancer of the colon?

• A. constipation, ascites, and mucus in the stool
• B. diarrhea, heartburn, and eructation
• C. blood in the stools, anemia, and 'pencil-shaped' stools
• D. anorexia, hematemesis, and increased peristalsis

Correct answer: C

Rationale: The correct symptoms associated with cancer of the colon are blood in the stools, anemia, and 'pencil-shaped' stools. These symptoms are classic indicators of colorectal cancer. Choices A, B, and D do not typically present in colorectal cancer. Constipation, ascites, and mucus in the stool are more commonly associated with other gastrointestinal conditions. Diarrhea, heartburn, and eructation are not typical symptoms of colon cancer. Anorexia, hematemesis, and increased peristalsis are more indicative of other gastrointestinal issues and not specific to colon cancer.

3. A nurse is providing dietary teaching to a client who has a new diagnosis of gastroesophageal reflux disease. Which of the following foods or beverages should the nurse recommend to minimize heartburn?

• A. Orange juice
• B. Decaffeinated coffee
• C. Peppermint
• D. Potatoes

Correct answer: D

Rationale: Potatoes are bland and less likely to relax the lower esophageal sphincter, making them a suitable choice to minimize heartburn in clients with gastroesophageal reflux disease. Orange juice and peppermint are acidic and can exacerbate GERD symptoms, while coffee, even decaffeinated, can stimulate acid production and worsen heartburn.

4. Through the client’s health history, you gather that Mr. Dizon smokes and drinks coffee. When taking the blood pressure of a client who recently smoked or drank coffee, how long should the nurse wait before taking the client’s blood pressure for accurate reading?

• A. 15 minutes
• B. 30 minutes
• C. 1 hour
• D. 5 minutes

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.

5. A client who 1) _____ diet requires 2) ___ amounts of vitamin C.

• A. A) Follows a vegan diet, B) More
• B. B) Smokes cigarettes, B) More
• C. A) Follows a vegan diet, C) The same
• D. B) Smokes cigarettes, C) The same

Correct answer: B

Rationale: The correct answer is B) Smokes cigarettes, More. Smoking increases the need for vitamin C as it can deplete the body's vitamin C levels. Vegan diets, on the other hand, require more vitamin C for optimal absorption due to the absence of heme iron, which enhances non-heme iron absorption. Choices A and C are incorrect because vegan diets require more vitamin C, while smoking increases the need for vitamin C.
