Submucosal glands occur in the submucosa of the and they also occur in the _.

Correct Answer: B

Rationale: The correct answer is B: Stomach and Duodenum. Submucosal glands are found in the submucosa of the stomach and duodenum. In the stomach, these glands secrete mucus and bicarbonate to protect the lining from stomach acid. In the duodenum, they secrete mucus to protect the lining from the acidic chyme entering from the stomach. Choices A, C, and D are incorrect because submucosal glands are not typically found in the oesophagus or ileum. The rationale for the correct answer is based on the anatomical location and function of submucosal glands in the gastrointestinal tract.

Correct Answer: B

Rationale: The correct answer is B: Providing skin care to the area around the tube site. This task can be safely delegated to an LPN/VN because it involves basic wound care and monitoring for signs of infection or skin breakdown. LPNs/VNs are trained to provide this type of care under the supervision of a registered nurse (RN). A: Assessing the patient's nutritional status weekly requires a higher level of assessment and interpretation of data, which is typically within the scope of an RN. C: Teaching the patient how to administer the feedings involves patient education and requires a higher level of critical thinking and assessment skills, typically performed by an RN. D: Determining the need for adding water to the feedings involves making clinical judgments and adjustments to the enteral nutrition plan, which should be overseen by an RN.

Correct Answer: A

Rationale: The correct answer is A. This patient reporting intermittent nausea may have altered nutritional intake, which warrants a referral to the dietitian for a complete nutritional assessment. Nausea can affect food intake and nutrient absorption, potentially leading to malnutrition. Options B, C, and D do not directly indicate a need for a dietitian referral based on the information provided. The patient with rheumatoid arthritis taking prednisone may benefit from dietary interventions, but the information provided does not specify any nutritional concerns. The patient with fluctuating weight gains and losses may have nutritional issues, but further details are needed to justify a dietitian referral. The patient admitted for debridement of an infected wound may have increased nutritional needs due to wound healing, but this alone does not warrant a dietitian referral without additional information on the patient's nutritional status.

Correct Answer: B

Rationale: The correct answer is B: 32. An average adult human has 32 permanent teeth, including 8 incisors, 4 canines, 8 premolars, and 12 molars. These teeth are developed during childhood and adolescence and are meant to last a lifetime, barring any dental issues. Option A (20) is too low for adult teeth count, C (30) is close but incorrect, and D (52) is too high and includes extra teeth, such as wisdom teeth which not everyone develops.

Correct Answer: B

Rationale: The correct answer is B: liver. The liver has the most metabolically active cells due to its crucial role in various metabolic processes, such as detoxification, protein synthesis, and glucose metabolism. It is responsible for producing enzymes and metabolizing nutrients. The pancreas, stomach, and small intestine are important organs, but they are not as metabolically active as the liver. The pancreas primarily produces digestive enzymes and regulates blood sugar levels. The stomach digests food, and the small intestine absorbs nutrients. However, in terms of overall metabolic activity, the liver surpasses these organs.
