,Q1. A patient with a sacral pressure injury (Stage 3) has a wound culture growing
Pseudomonas aeruginosa. The provider orders 1 g ceftazidime IV every 8 hours. The
patient's estimated creatinine clearance is 20 mL/min. Based on pharmacokinetic
principles, which adjustment is most appropriate?
A. Administer 1 g every 12 hours
B. Administer 1 g every 24 hours
C. Administer 500 mg every 8 hours
D. Administer 500 mg every 12 hours
Correct Answer: B. Administer 1 g every 24 hours
Rationale: Ceftazidime is primarily renally excreted; with CrCl 20 mL/min, the dosing
interval should be extended to every 24 hours to prevent accumulation and toxicity.
Options A, C, and D do not appropriately adjust for this degree of renal impairment.
Why Wrong:
A - Every 12 hours is too frequent for CrCl 20 mL/min, risking drug accumulation.
C - Reducing the dose without extending the interval does not adequately account for
reduced clearance.
D - Both dose reduction and interval extension are needed; this option does not match
standard guidelines.
Reference: Lexicomp. (2024). Ceftazidime: Drug information.
Q2. Which finding most clearly distinguishes a Stage 2 pressure injury from a Stage 3
pressure injury?
A. Presence of slough in the wound bed
B. Depth of tissue involvement
C. Size of the wound surface area
D. Location on the body
Correct Answer: B. Depth of tissue involvement
Rationale: Staging is based on the depth of tissue damage: Stage 2 is partial-thickness
with dermis exposed, while Stage 3 involves full-thickness loss with subcutaneous fat
visible. Slough, size, and location are not primary staging criteria.
Why Wrong:
A - Slough can be present in deeper stages but is not a differentiating criterion
between stages.
C - Surface area does not determine stage; depth is the key factor.
D - Location does not influence staging.

Ulcers/Injuries: Clinical Practice Guideline.

, Q3. A patient with a venous stasis ulcer has a dressing that adheres to the wound bed.
Which dressing property is most important to minimize trauma during dressing
changes?
A. High absorbency
B. Moisture-retentive
C. Nonadherent contact layer
D. Occlusive backing
Correct Answer: C. Nonadherent contact layer
Rationale: A nonadherent contact layer prevents the dressing from sticking to the wound
bed, thereby reducing trauma to newly formed granulation tissue. While moisture
retention, absorbency, and occlusion are beneficial, they do not directly address
adherence.
Why Wrong:
A - Absorbency manages exudate but does not prevent adherence.
B - Moisture retention supports healing but does not prevent dressing adherence.
D - Occlusive backing provides a barrier but does not affect the contact layer's
adherence.

Management of Wounds in Patients with Lower-Extremity Venous Disease.
Q4. Which laboratory value is most critical to monitor during the use of negative
pressure wound therapy (NPWT) over a large wound?
A. Serum potassium
B. Serum sodium
C. Hematocrit
D. Serum calcium
Correct Answer: C. Hematocrit
Rationale: NPWT can cause significant blood loss, especially with large wounds or if the
foam is changed aggressively; monitoring hematocrit/hemoglobin is essential. Electrolyte
imbalances are less directly related.
Why Wrong:
A - Potassium is not specifically affected by NPWT.
B - Sodium is not directly affected by NPWT.
D - Calcium is not typically monitored in this context.

Q5. A patient with a shallow, exudating wound on the sacrum has a suspected
infection. Which wound culture technique yields the most reliable results?
A. Swab of the wound surface
