Question 1 of 5
Which enzyme digests fiber in the large intestine?
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.
Question 2 of 5
Electrolytes create _____, which is caused by water following electrolytes within or between cells.
Correct Answer: D
Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

Question 4 of 5
A patient with renal insufficiency should limit the intake of which of the following nutrients?
Correct Answer: A
Rationale: In patients with renal insufficiency, impaired kidney function can lead to difficulty in excreting phosphorus. High phosphorus levels can result in further complications such as bone and heart problems. Therefore, limiting the intake of phosphorus is crucial. Potassium and sodium restrictions may also be necessary in renal insufficiency, but the primary concern related to nutrients is phosphorus in this scenario. Calcium, while important for bone health, does not typically need to be restricted in renal insufficiency unless there is a specific medical reason to do so.
Question 5 of 5
A vegan patient might be at risk for deficiency in which of the following nutrients?
Correct Answer: A
Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.
