A hepatic cord is:

Correct Answer: C

Rationale: The correct answer is C because a hepatic cord refers to a row of adjacent hepatocytes within a liver lobule, which are the functional units of the liver responsible for various metabolic functions. This structure is essential for liver function and is where processes like detoxification and metabolism occur. Choice A is incorrect because a hepatic cord is not another name for a branch of the portal vein. Choice B is incorrect because the tough connective tissue surrounding a portal triad is known as Glisson's capsule, not a hepatic cord. Choice D is incorrect as a hepatic cord is not a branch of the bile duct. Overall, understanding the anatomical structure and function of the liver is crucial in determining the correct answer.

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, Magnesium Hydroxide (Maalox), as it is an antacid that works by neutralizing stomach acid. Omeprazole (A) is a proton pump inhibitor that reduces acid production, not neutralizes it. Metoclopramide (B) is a prokinetic agent used for gastrointestinal motility disorders. Cimetidine (C) is an H2 receptor antagonist that decreases stomach acid production but doesn't directly neutralize acid like an antacid. Therefore, D is the correct choice as it directly acts to neutralize stomach acid.

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.
