The nurse is obtaining a history of a patient with hepatitis Which question is most appropriate for the nurse to ask?

Correct Answer: D

Rationale: The correct answer is D because consuming contaminated shellfish can lead to Hepatitis A infection. It is important to ask about dietary habits to identify potential sources of infection. Choice A is incorrect as it assumes drug use, which may not be relevant to the patient. Choice B is more focused on sexual behavior rather than Hepatitis transmission. Choice C is irrelevant unless there was a known Hepatitis outbreak in Canada.

Correct Answer: C

Rationale: The correct answer is C because the enteric nervous system is a complex network of neurons that controls digestion independently of the brain. It regulates gastrointestinal functions such as peristalsis, secretion of digestive enzymes, and blood flow. This system can operate autonomously but is also influenced by the central nervous system. Choices A, B, and D are incorrect because the enteric nervous system is not responsible for controlling voluntary movements, regulating hormone secretion, or controlling respiratory functions.

Correct Answer: B

Rationale: The correct answer is B: liver. The liver is responsible for the production of bile, which is a greenish-yellow fluid that aids in digestion by emulsifying fats. Bile is stored and concentrated in the gallbladder (not produced by it). The pancreas produces digestive enzymes, not bile. The small intestine is where bile is released to help with the digestion of fats, but it is not responsible for its production. Therefore, the liver is the correct answer as it is the primary organ involved in bile production.

Correct Answer: B

Rationale: The correct answer is B: stomach. The stomach is responsible for mechanical digestion through the churning and mixing of food with gastric juices, breaking it down into smaller particles. The mouth initiates digestion by chewing and mixing food with saliva, but it primarily focuses on chemical digestion through enzymes. The small intestine is where most of the chemical digestion and nutrient absorption occur, not mechanical digestion. The large intestine's main function is water absorption and the formation of feces, not mechanical digestion. Therefore, the stomach is the correct choice for mechanical digestion in the digestive system.

Correct Answer: A

Rationale: The correct answer is A: parietal cells. Parietal cells are the specific type of cell in the stomach responsible for secreting hydrochloric acid. They play a crucial role in the digestion process by creating an acidic environment necessary for the activation of digestive enzymes and breakdown of food. Chief cells mainly produce pepsinogen, mucous cells secrete mucus for protection, and enteric cells are related to the enteric nervous system, not acid secretion in the stomach. Therefore, parietal cells are the correct choice for this question.
