Correct Answer: D

Rationale: The correct answer is D: Understands discharge instructions. This is crucial for patient safety and recovery post-surgery. Understanding discharge instructions ensures patients know how to care for themselves at home, manage medications, recognize warning signs, and follow-up instructions. Choice A is incorrect as patients should not drive after surgery due to potential impairment. Choice B is incorrect as IV narcotics administration timing is not a discharge criterion. Choice C is irrelevant to the patient's readiness for discharge. Understanding discharge instructions is the key factor in ensuring the patient's well-being and recovery after ambulatory surgery.

Correct Answer: A

Rationale: The correct answer is A: Type I hypersensitivity reaction. In Type I hypersensitivity, anaphylactic reactions involve immediate IgE-mediated responses to allergens, leading to histamine release and potentially life-threatening symptoms. This type of reaction is characterized by rapid onset and systemic involvement. Choices B, C, and D are incorrect because Type III reactions involve immune complex deposition leading to inflammation (B), Type II reactions involve cytotoxic antibodies targeting cells (C), and Type IV reactions involve delayed cell-mediated responses (D).

Correct Answer: A

Rationale: The correct answer is A: Otorrhea. Otorrhea refers to the discharge of fluid from the ear, indicating an abnormal finding of ear drainage. This term specifically describes the symptom of ear drainage, making it the most appropriate choice for documenting this finding. Otalgia (choice B) refers to ear pain, ototoxic (choice C) refers to substances that are harmful to the ear, and tinnitus (choice D) refers to ringing in the ears, none of which accurately describe ear drainage. Therefore, the correct choice is A as it specifically addresses the symptom of ear drainage.

Correct Answer: A

Rationale: The correct answer is A: Phagocytosis. Macrophages and neutrophils are both types of phagocytes responsible for engulfing and digesting pathogens such as bacteria. This process helps in clearing infections and maintaining immune homeostasis. Summary: - Choice B (Complement fixation) is incorrect as it refers to a process where complement proteins bind to pathogens to enhance their removal by phagocytes. - Choice C (Antibody production) is incorrect as macrophages and neutrophils do not produce antibodies. They mainly rely on phagocytosis for pathogen clearance. - Choice D (Suppression of autoimmunity) is incorrect as these cells are involved in innate immunity and do not play a direct role in regulating autoimmunity.
