The client has a chronic tissue injury. Upon examining the client's antibody for a particular cellular response, Which of the following WBC component is responsible for phagocytosis in chronic tissue injury?

Correct Answer: D

Rationale: In chronic tissue injury, monocytes (D) are the key white blood cells (WBCs) for phagocytosis. They transform into macrophages, which persist in tissues, engulfing debris and pathogens over time. Neutrophils (A) dominate acute inflammation, arriving early but dying off quickly. Basophils (B) release histamine in allergic responses, not phagocytosis. Eosinophils (C) target parasites and allergies, not chronic injury cleanup. Chronic conditions require sustained immune action, and monocytes/macrophages excel here, unlike the short-lived neutrophils of acute phases. This cellular adaptation to prolonged injury makes D the correct choice.

Correct Answer: C

Rationale: Crisis doesn't last 4 months (C); it's acute, typically resolving within 6 weeks, per crisis theory (e.g., Caplan). Heightened stress (A), disorganized function (B), and unpleasant feelings (D) are true. C's prolonged duration misaligns with crisis' short-term nature, making it the untrue statement.

Correct Answer: C

Rationale: p.c.' means after meals (C), from Latin 'post cibum,' per pharmacology. As desired (A) is 'ad lib,' before meals (B) 'a.c.,' bedtime (D) 'h.s.' C fits Maalox's post-meal use, making it correct.

Correct Answer: C

Rationale: Efficiency (C) in the nursing process ensures proper use of resources time, staff, costs per management principles. Organized/systematic (A) structures, humanistic (B) cares, effective (D) achieves goals. C targets resource optimization, making it correct.

Correct Answer: D

Rationale: Pulse rate assessment involves measuring the heart rate, typically at the radial artery, and noting whether it exceeds the normal range of 60-100 beats per minute in adults. When the pulse rate is above normal, it indicates an accelerated heart rate, which is medically termed tachycardia (D), defined as a heart rate exceeding 100 beats per minute at rest. Tachypnea (A) refers to rapid breathing, not heart rate, and is unrelated to pulse findings. Hyperpyrexia (B) denotes an extremely high fever (typically above 41.5°C), which could cause a rapid pulse but is a temperature-related term, not a direct pulse descriptor. Arrhythmia (C) indicates an irregular heart rhythm, which may or may not involve an elevated rate; however, the question specifies only an above-normal rate without mentioning irregularity. Thus, tachycardia is the precise term for documenting a pulse rate above normal, making D the correct answer. This distinction is critical in nursing to ensure accurate communication of clinical findings.
