Fat-storing stellate cells (Ito cells) in the space of Disse are noted for storing:

Correct Answer: D

Rationale: The correct answer is D: vitamin A. Fat-storing stellate cells, also known as Ito cells, are specialized cells found in the liver's space of Disse. These cells are primarily responsible for storing vitamin A. Vitamin A is crucial for various functions in the body, such as vision, immune function, and cell growth. Storing excess vitamin A in the liver helps maintain a steady supply for when needed. Now, let's analyze why the other choices are incorrect: A: Glycogen is stored in hepatocytes, not in fat-storing stellate cells. B: Glucose is stored in the form of glycogen in the liver, not in fat-storing stellate cells. C: Albumin is a protein synthesized by the liver but is not stored in fat-storing stellate cells.

Correct Answer: D

Rationale: The correct answer is D: Limit. Limit is not considered a right of medication because it does not fall under the standard "5 Rights of Medication Administration" (Right patient, Right drug, Right dose, Right route, Right time). The other options (A: Dose, B: Time, C: Route) are all considered essential rights of medication administration to ensure safe and effective treatment. Limit is not a standard consideration when administering medication as it does not pertain to the specific details of how the medication should be given to the patient.

Correct Answer: D

Rationale: The correct answer is D because all of the choices activate sensors in the walls of digestive organs. A: Breakdown products of digestion trigger chemoreceptors. B: Distension activates mechanoreceptors in response to stretching of the organ walls. C: pH of chyme activates pH receptors. Therefore, all three stimuli play a role in signaling the digestive system to regulate processes like secretion and motility.

Correct Answer: B

Rationale: The correct answer is B: proximal small intestine. Most digestion occurs in the proximal small intestine due to the presence of enzymes such as amylase, lipase, and protease, which break down carbohydrates, fats, and proteins, respectively. Additionally, bile and pancreatic juices are released in this part of the intestine to aid in digestion. The stomach primarily initiates digestion by breaking down food with stomach acid and enzymes, but the majority of nutrient absorption occurs in the small intestine. Choices A, C, and D are incorrect as the stomach is not the main site of digestion, the distal small intestine is more focused on absorption rather than digestion, and the ascending colon is primarily responsible for water absorption and formation of feces.

Correct Answer: C

Rationale: The correct answer is C: esophagus. An accessory organ is one that aids in digestion but is not part of the digestive tract. The esophagus is part of the digestive tract, responsible for transporting food from the mouth to the stomach. The pancreas, liver, and gallbladder are all accessory organs as they play a role in digestion but are not directly part of the digestive tract. Pancreas produces enzymes for digestion, liver produces bile for fat digestion, and gallbladder stores and releases bile. Therefore, the esophagus is the correct answer as it is not an accessory organ.
