Which of the following is not considered a right of medication?

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: 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.

Correct Answer: D

Rationale: The correct answer is D: muscularis. The muscularis layer of the intestinal wall is responsible for peristalsis, the wave-like contractions that propel food through the digestive tract. The mucosa (A) is the innermost layer involved in absorption, not movement. The submucosa (B) provides support and nourishment to the mucosa. The adventitia (C) refers to connective tissue that surrounds organs, not directly involved in movement. Therefore, the muscularis (D) is the only layer specifically responsible for changing the shape of the intestinal lumen and moving food along its length.

Correct Answer: D

Rationale: The correct answer is D: cuspids. Cuspids, also known as canines, are pointed teeth that are specifically adapted for tearing and shredding food. They have long, sharp points that help in grasping and cutting food. Incisors (A) are flat-front teeth used for cutting and biting. Bicuspids (B) are premolars with two cusps used for grinding food. Molars (C) are large, flat teeth at the back of the mouth used for grinding and chewing. Therefore, D is the correct answer as cuspids are the pointed teeth adapted for tearing and shredding.
