PREP WITH COMPLETE QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+ (MOST
RECENT!!)
**1. A 60-year-old male with a history of lymphatic dysfunction
presents with extensive edema in both lower extremities and multiple
venous ulcers. Which compression therapy would be most
appropriate?**
A. Unna boot changed weekly
B. Multi-layer compression system
C. Low-compression stockings
D. Intermittent pneumatic compression
**Correct Answer: B. Multi-layer compression system**
**Rationale:** Multi-layer compression systems provide sustained,
high-level pressure (30-40 mmHg at the ankle) necessary to counteract
high venous pressure and chronic edema in patients with lymphatic
dysfunction, whereas Unna boots may not provide adequate sustained
compression for severe edema .
,**2. A 76-year-old female presents with a post-surgical wound
infection. Which technique is most appropriate for obtaining a wound
culture?**
A. Swabbing the superficial exudate
B. Aspirating purulent fluid from deep within the wound
C. Cleansing with povidone-iodine before swabbing
D. Using a swab to collect dry eschar
**Correct Answer: B. Aspirating purulent fluid from deep within the
wound**
**Rationale:** Needle aspiration of purulent fluid or tissue biopsy is
the gold standard for identifying the causative organism in a wound
infection, as it bypasses surface colonizers. Superficial swabs often
capture biofilm or colonizing bacteria rather than the pathogen causing
the infection .
**3. A 48-year-old female has a chronic wound with hypertrophic
granulation tissue and a confirmed biofilm. Which intervention is most
likely to disrupt the biofilm?**
A. Application of silver sulfadiazine cream
B. Daily cleansing with normal saline
C. Enzymatic debridement only
D. Aggressive sharp debridement
**Correct Answer: D. Aggressive sharp debridement**
**Rationale:** Biofilm is a structured community of bacteria resistant
to antibiotics and antiseptics. Physical disruption through aggressive
, sharp debridement is the most effective method to remove biofilm and
allow healing to proceed. Enzymatic agents alone are often insufficient
to penetrate mature biofilm .
**4. A 66-year-old with chronic lymphocytic leukemia (CLL) has a non-
healing surgical wound. What is the most appropriate intervention?**
A. Apply a topical antibiotic
B. Initiate strict isolation precautions
C. Coordinate with oncology to manage leukopenia
D. Debride the wound aggressively daily
**Correct Answer: C. Coordinate with oncology to manage
leukopenia**
**Rationale:** In immunocompromised patients (e.g., CLL), wound
healing is heavily dependent on systemic factors. Managing leukopenia
and addressing the underlying immunosuppression is crucial to enable
the immune system to support wound healing and fight infection .
**5. A 30-year-old with Crohn's disease has an enterocutaneous fistula.
Which education technique promotes autonomy?**
A. Instructing the caregiver to perform all dressing changes
B. Providing written instructions only
C. Teaching the patient to select and apply pouching systems
independently
D. Restricting fluid intake to decrease output
