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: Correct Answer: A Rationale: 1. Asking if the patient feels the need to go to the bathroom helps assess urgency. 2. Urinary retention may lead to the inability to sense the urge to void. 3. This question directly addresses the issue of voiding, crucial in diagnosing urinary retention. Summary: B: Mobility is not directly related to urinary retention. C: Medication timing is important but not directly related to urinary retention. D: Safety rail inquiry is more related to fall prevention, not urinary retention.

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.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be observed or measured by others. In this case, choice C is correct because the patient describing excitement about discharge is personal and based on the patient's feelings or perceptions. This is subjective data because it is based on the patient's own experiences and emotions. Choices A and B are incorrect because patient's temperature and wound appearance are objective data that can be measured or observed by the nurse. Choice D is also incorrect as patient pacing the floor is an observable behavior, making it objective data. Therefore, choice C is the correct answer as it represents subjective data in the context of the assessment.

Correct Answer: A

Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.
