Which action for a patient receiving enteral nutrition through a percutaneous endoscopic gastrostomy (PEG) may be delegated to a licensed practical/vocational nurse (LPN/VN)?

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: 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.

Correct Answer: D

Rationale: The correct answer is D: greater omentum. The greater omentum is a membrane that hangs like an apron over the intestines, providing protection and insulation. It consists of fatty tissue and helps to limit the spread of infection within the abdominal cavity. The mesentery (choice A) is a different structure that attaches the intestines to the abdominal wall. The visceral peritoneum (choice B) is the inner layer of the peritoneum that covers the organs, while the parietal peritoneum (choice C) is the outer layer that lines the abdominal cavity. Therefore, the greater omentum is the correct choice in this context.

Correct Answer: C

Rationale: The correct answer is C: D. Vitamin D is fat-soluble because it can be stored in the body's fatty tissues and liver. This allows for a slower release into the bloodstream when needed. Vitamins B12, C, and E are water-soluble, meaning they dissolve in water and are not stored in the body. Vitamin B12 is stored in the liver, but it is not considered fat-soluble. Vitamin C is excreted through urine, and Vitamin E is stored in body tissues but not in fat. Therefore, the only fat-soluble vitamin among the options provided is Vitamin D.
