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. What type of diet would most likely benefit a patient with cystic fibrosis?
- A. Low sodium
- B. Low fat
- C. Clear liquid
- D. High calorie, high protein
Correct answer: D
Rationale: Patients with cystic fibrosis often have malabsorption issues, leading to increased energy needs. A high-calorie, high-protein diet is recommended to help meet these needs, support growth, and maintain overall health. Choices A, B, and C do not address the specific dietary requirements associated with cystic fibrosis, making them less beneficial for these patients.
3. What is the purpose of the cuff in a Tracheostomy tube?
- A. Separate the upper and lower airway
- B. Separate trachea from the esophagus
- C. Separate the larynx from the nasopharynx
- D. Secure the placement of the tube
Correct answer: B
Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.
4. A nurse is teaching a client about complete and incomplete proteins. Which of the following foods should the nurse include in the teaching as an incomplete protein?
- A. 4 oz chickpeas
- B. 2 poached eggs
- C. 2 oz cheddar cheese
- D. 4 oz salmon fillet
Correct answer: A
Rationale: The correct answer is A: 4 oz chickpeas. Chickpeas are considered an incomplete protein because they lack one or more essential amino acids required by the body. Incomplete proteins do not provide all essential amino acids in sufficient quantities. Choice B, 2 poached eggs, is a complete protein source because eggs contain all essential amino acids. Choice C, 2 oz cheddar cheese, is also a complete protein as it contains all essential amino acids. Choice D, 4 oz salmon fillet, is another complete protein source as fish typically provide all essential amino acids needed by the body.
5. When assessing Richard for chest percussion or chest vibration and postural drainage, Mario would focus on the following EXCEPT:
- A. Amount of food and fluid taken during the last meal before treatment
- B. Respiratory rate, breath sounds, and location of congestion
- C. Teaching the client's relatives to perform the procedure
- D. Doctor's order regarding position restrictions and client's tolerance for lying flat
Correct answer: B
Rationale: The correct answer is B because when assessing Richard for chest percussion or chest vibration and postural drainage, Mario would focus on various aspects such as the amount of food and fluid taken before treatment to prevent complications during the procedure, teaching the client's relatives to perform the procedure correctly, and following the doctor's orders regarding position restrictions and the client's tolerance for lying flat. Respiratory rate, breath sounds, and location of congestion would be assessed during the procedure itself, not as part of the pre-assessment.
