Which of the following WBC component proliferates in cases of Anaphylaxis?

Correct Answer: C

Rationale: In anaphylaxis, a severe allergic reaction, eosinophils (C) proliferate due to their role in combating allergens and parasites via histamine release and inflammation modulation. Neutrophils (A) focus on bacterial infections, not allergies. Basophils (B) release histamine too, but their numbers don't surge as eosinophils do in allergic states; they initiate the response. Monocytes (D) handle chronic inflammation, not acute hypersensitivity. Eosinophils rise in blood and tissues during anaphylaxis, reflecting their specialization in allergic conditions, making C the correct answer based on immunological specificity.

Correct Answer: B

Rationale: A crisis characteristic is a triggering event (B), a sudden disruption (e.g., loss), per Caplan. It's time-limited (not A), dangerous (not C), and involves the whole person (not D). B's trigger is core to crisis definition, making it correct.

Correct Answer: B

Rationale: Od' means right eye (B), from Latin 'oculus dexter,' per ophthalmic terms. Left eye (A) is 'os,' both eyes (C) 'ou,' once a day (D) 'qd.' B aligns with Maxitrol's eye-specific use, making it correct.

Correct Answer: B

Rationale: Humanistic (B) addresses individualized care, focusing on the client's unique needs, per nursing philosophy. Organized/systematic (A) structures, efficient (C) saves resources, effective (D) meets outcomes. B ensures personalization, making it correct.

Correct Answer: B

Rationale: Using a wide base of support is a fundamental principle of body mechanics in nursing to ensure stability, safety, and injury prevention for both the nurse and the client during transfers. Option B facing the client, bending the knees, and placing hands on the client's forearms while lifting correctly incorporates this principle. Bending the knees lowers the nurse's center of gravity, and facing the client allows for a forward weight shift while keeping the spine aligned. Placing hands on the forearms provides a secure grip and encourages the client to assist, while the nurse's feet, naturally apart in this stance, create a wide base for balance. Option A (bending at the waist) risks back injury due to poor spinal alignment and lacks mention of foot positioning. Option C (spreading feet apart) is a component of a wide base but is incomplete as a standalone action for lifting. Option D (tightening pelvic muscles) is irrelevant to establishing a base of support and pertains more to the client's effort than the nurse's technique. Thus, B is the most comprehensive and mechanically sound choice.
