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. A client with gastroesophageal reflux disease (GERD) is receiving teaching from a nurse. Which of the following instructions should the nurse include?
- A. Lie down after meals to reduce discomfort.
- B. Limit fluid intake to 1 liter per day.
- C. Avoid eating spicy foods.
- D. Eat three large meals each day.
Correct answer: C
Rationale: The correct answer is C: 'Avoid eating spicy foods.' Spicy foods can exacerbate symptoms of GERD by irritating the esophagus and causing discomfort. It is important for clients with GERD to avoid spicy foods to help manage their condition. Choices A, B, and D are incorrect. A client with GERD should not lie down after meals as this can worsen symptoms, limiting fluid intake to only 1 liter per day may not be appropriate for everyone, and eating three large meals each day can put pressure on the stomach and worsen GERD symptoms.
3. A client with cirrhosis is experiencing ascites. Which dietary instruction should the nurse provide?
- A. Increase protein intake.
- B. Limit fluid intake to 1500 mL/day.
- C. Consume a low-sodium diet.
- D. Take a daily multivitamin.
Correct answer: C
Rationale: For a client with cirrhosis experiencing ascites, the nurse should instruct them to consume a low-sodium diet. This dietary modification helps reduce fluid retention and manage ascites by decreasing the amount of sodium in the body, which helps prevent fluid accumulation in the abdomen. Limiting sodium intake is crucial in managing ascites and preventing further complications in clients with cirrhosis.
4. Organ systems consist of organs, which consist of tissues.
- A. True
- B. False
- C. Not Sure
- D. None of the above
Correct answer: A
Rationale: The statement is true. Organ systems are made up of organs, which in turn are composed of tissues. Organs are structures made up of two or more types of tissues that work together to perform specific functions. Tissues, on the other hand, are groups of cells that work together to perform a specific function. Therefore, organs are made up of tissues, and organ systems consist of organs.
5. Which of the following electrolytes plays an essential role in the clotting of blood?
- A. sodium
- B. magnesium
- C. calcium
- D. potassium
Correct answer: C: calcium
Rationale: Calcium plays an essential role in the clotting of blood by being involved in several steps of the coagulation process. It is necessary for the conversion of prothrombin to thrombin, which is a crucial step in forming blood clots. Sodium, magnesium, and potassium do not directly participate in the clotting cascade and are not associated with the coagulation process. Therefore, the correct answer is calcium.
