Stomach's defense against infection

Correct Answer: B

Rationale: The correct answer is B, the hydrochloric acid. The stomach's defense against infection is mainly attributed to its acidic environment, created by the hydrochloric acid. This acid helps to kill ingested pathogens, preventing them from causing infections. Additionally, the low pH of the stomach acid aids in the breakdown of food and the activation of digestive enzymes. The other choices are incorrect as the intestines do not directly play a role in the stomach's defense against infection.

Correct Answer: A

Rationale: The correct answer is A because if the patient is looking pale during activities, lying on a bed can help reduce physical exertion and promote rest, aiding in the recovery of the pale appearance. Choice B, performing a DBE (Deep Breathing Exercise), may not directly address the underlying cause of the paleness. Choice C and D are incomplete or irrelevant options. In summary, choice A is correct as it addresses the immediate need for rest and reduced activity level to help the patient recover from the pale appearance.
