A nurse is caring for a patient receiving a peripheral IV infusion of Vancomycin. During the infusion, the patient reports intense burning and pain at the site. Upon assessment, the nurse notes severe erythema, edema extending 3 inches proximal to the insertion site, and a palpable venous cord. Which action should the nurse take FIRST?
A) Apply a cold compress to the site and slow the Vancomycin infusion rate by 50%.
B) Stop the infusion immediately, disconnect the IV tubing, and elevate the extremity.
C) Flush the IV catheter with 10 mL of 0.9% Normal Saline to test catheter patency.
D) Administer a prescribed IV antihistamine and re-evaluate the site in 15 minutes.
CORRECT ANSWER: B) Stop the infusion immediately, disconnect the IV tubing, and elevate the extremity.
RATIONALE: The patient is exhibiting signs of Grade 3-4 phlebitis/vesicant irritation (erythema, edema, palpable venous cord). The immediate priority nursing action for any IV complication involving pain, swelling, or phlebitis is to STOP the infusion immediately to prevent further tissue damage, disconnect the tubing, remove the catheter, and elevate the limb.
CORRECT ANSWER: A) 0.375 mL every 15 seconds
RATIONALE: First calculate total volume: 15 mg / (5 mg/mL) = 3 mL total dose. Over 2 minutes (120 seconds), there are 8 intervals of 15 seconds (120 / 15 = 8). Divide total volume by intervals: 3 mL / 8 = 0.375 mL every 15 seconds.
CORRECT ANSWER: C) Waste the 0.6 mL into an approved waste receptacle in the presence of a second licensed nurse who co-signs the eMAR.
RATIONALE: Controlled substances (like Morphine) require a physical second-nurse witness during the immediate wasting process prior to administration, with both nurses verifying the amount wasted and co-signing the electronic record.
CORRECT ANSWER: B) 4.2 mL
RATIONALE: Step 1: Convert weight to kg: 33 lb / 2.2 = 15 kg. Step 2: Calculate total daily dose: 15 kg * 14 mg/kg = 210 mg/day. Step 3: Divide into 2 doses: 210 mg / 2 = 105 mg per dose. Step 4: Calculate volume: (105 mg / 125 mg) * 5 mL = 0.84 * 5 = 4.2 mL per dose.
CORRECT ANSWER: C) Recalculate the drip rate based on the prescriber's original 8-hour order parameters and notify the provider of the delay.
RATIONALE: Never 'catch up' IV fluids—especially solutions containing potassium or administered to heart failure patients—due to the risk of fluid overload and lethal hyperkalemia. The nurse unkinks the line, recalculates the safe rate based on orders/policy, and notifies the prescriber.
CORRECT ANSWER: B) Infiltration
RATIONALE: Infiltration is the inadvertent administration of a non-vesicant solution into surrounding subcutaneous tissue, characterized by pale, cool, taut skin and swelling/edema. (Extravasation involves vesicants causing tissue necrosis; phlebitis is warm, red, and tender).
CORRECT ANSWER: B) Write down the order, read back the complete order verbatim to the physician, and receive verbal confirmation.
RATIONALE: For emergency verbal orders, the nurse must execute the mandatory 'Write Down, Read Back, and Confirm' process prior to administration to prevent critical communication errors.
CORRECT ANSWER: D) Enoxaparin 40 mg SC daily at 0900
RATIONALE: Option D uses safe notation. Option A lacks a leading zero ('.5 mg' should be '0.5 mg'); Option B contains a trailing zero ('50.0 mcg' should be '50 mcg'); Option C uses 'U' which is on the Do Not Use list (must write 'units').
CORRECT ANSWER: B) Administering the IVPB via rapid IV push injection using a 10 mL syringe.
RATIONALE: IV Potassium Chloride MUST NEVER be given as an IV push or bolus, as rapid IV administration causes fatal cardiac arrest. It must always be diluted and infused slowly via an infusion pump.
CORRECT ANSWER: A) Sudden severe headache, flushing of the face, tightness in the chest, rapid irregular pulse, and severe hypotension.
RATIONALE: Speed shock is a systemic reaction occurring when a substance is injected into the circulatory system too rapidly. Symptoms include facial flushing, severe pounding headache, chest tightness, irregular pulse, syncope, and shock.
CORRECT ANSWER: B) Hang the secondary IVPB bag higher than the primary IV bag using an extension hook on the primary bag.
RATIONALE: To infuse a secondary IVPB by gravity, the secondary bag must be hung HIGHER than the primary bag so that hydrostatic pressure closes the back-check valve on the primary line until the secondary bag empties.
CORRECT ANSWER: C) 150 mL/hr
RATIONALE: Convert 1.5 Liters to mL: 1.5 L * 1,000 mL/L = 1,500 mL. Divide total volume by total hours: 1,500 mL / 10 hours = 150 mL/hr.
CORRECT ANSWER: C) Assess the patient's current blood pressure and pulse, provide education on the drug, and explore their concerns.
RATIONALE: When a patient refuses medication, the nurse's initial responsibility is to assess the patient's vital signs and clinical status, explore the reasons for refusal, and provide education while upholding the patient's right to refuse.
CORRECT ANSWER: B) 100 gtt/min
RATIONALE: Drip rate formula: (Volume in mL / Time in minutes) * Drop Factor = (100 mL / 60 min) * 60 gtt/mL = 100 gtt/min. (Note: with microdrip 60 gtt/mL, gtt/min always equals mL/hr).
CORRECT ANSWER: B) Trendelenburg position on the left side (left lateral Trendelenburg).
RATIONALE: For an air embolism, immediately place the patient in Left Lateral Trendelenburg position. This traps the air bubble in the apex of the right ventricle, preventing it from entering the pulmonary artery.
CORRECT ANSWER: B) To clear any remaining medication from the catheter lumen into the vein and maintain catheter patency.
RATIONALE: The post-medication saline flush clears all residual drug from the dead space of the catheter lumen into the bloodstream and prevents clot formation or drug precipitation.
CORRECT ANSWER: B) Calculate total 24-hour acetaminophen intake to ensure it does not exceed the maximum 4,000 mg (4 g) daily limit.
RATIONALE: Acetaminophen has a strict maximum daily dose limit (4,000 mg / 24 hr for adults; often 3,000 mg in clinical guidelines) to prevent severe hepatotoxicity. The nurse must sum all sources (including combo opioids).
CORRECT ANSWER: A) 0.5 tablet
RATIONALE: Convert 0.125 mg to mcg: 0.125 mg * 1,000 mcg/mg = 125 mcg. Calculate tablets: Desired / Have = 125 mcg / 250 mcg = 0.5 tablet.
CORRECT ANSWER: D) 10 mL or larger barrel syringe
RATIONALE: Smaller syringes (1, 3, or 5 mL) generate excessively high injection pressure (PSI) that can rupture central line lumen walls. Always use a 10 mL or larger syringe for flushing central venous catheters.
CORRECT ANSWER: B) 'I have the right to know what medication is in this IV bag, its intended purpose, and potential side effects before it infuses.'
RATIONALE: Patient rights mandate informed consent/refusal and the Right to Education regarding the name, purpose, action, and potential adverse effects of any administered treatment.
CORRECT ANSWER: B) Perform jaw-thrust/chin-lift maneuver, notify the anesthesia provider immediately, and prepare for emergency airway intervention.
RATIONALE: Stridor indicates upper airway obstruction or laryngospasm—a life-threatening emergency. Priority is airway management: repositioning airway, emergency call, suction, and preparation for re-intubation.
CORRECT ANSWER: B) Dantrolene sodium
RATIONALE: The patient is exhibiting classic signs of Malignant Hyperthermia (unexplained hypercarbia, masseter spasm, hyperthermia, rigidity). Dantrolene sodium is the specific skeletal muscle relaxant used to treat MH.
CORRECT ANSWER: B) Hypovolemic shock / internal hemorrhage
RATIONALE: Tachycardia, hypotension, oliguria (<30 mL/hr), and pale/clammy skin are classic manifestations of hypovolemic shock resulting from surgical hemorrhage or severe fluid deficit.
CORRECT ANSWER: D) 'I can take my full dose of aspirin and ibuprofen on the morning of surgery with a sip of water.'
RATIONALE: NSAIDs and Aspirin inhibit platelet aggregation and must be held 7 to 10 days prior to elective surgery to prevent intraoperative and postoperative surgical hemorrhage.
CORRECT ANSWER: B) Blood pressure drops from 128/82 mmHg to 88/50 mmHg with a heart rate of 52 beats/min.
RATIONALE: Spinal anesthesia blocks sympathetic vasomotor nerves, leading to venous pooling and severe hypotension/bradycardia. Marked hypotension requires immediate intervention (fluids, vasopressors, leg elevation).
CORRECT ANSWER: C) Emergency surgery
RATIONALE: Emergency surgery must be performed immediately without delay to preserve life or limb (e.g., ruptured appendix, massive trauma, repair of expanding abdominal aortic aneurysm).
CORRECT ANSWER: B) Use a certified medical interpreter to translate the surgeon's explanation and witness the patient's voluntary signature.
RATIONALE: Informed consent requires clear understanding. A certified medical interpreter must be utilized for limited English proficiency patients. Family members should not translate medical consent.
CORRECT ANSWER: B) Confirming that the patient signed the document voluntarily, possesses decision-making capacity, and is the person named.
RATIONALE: The nurse's signature as a witness attests ONLY that the patient signed voluntarily, is competent to sign, and that the signature is authentic. The surgeon remains legally responsible for informing the patient.
CORRECT ANSWER: C) A required discussion occurs between the patient/proxy, surgeon, and anesthesiologist to decide whether to suspend or modify the DNR order temporarily during surgery.
RATIONALE: Perioperative DNR/MOLST policies require required reconsideration: an explicit discussion between the patient/proxy and surgical/anesthesia team to decide whether DNR orders are temporarily suspended or modified during the procedure.
CORRECT ANSWER: A) Correct patient identity, correct surgical procedure, correct surgical site/side, and correct patient positioning.
RATIONALE: The Universal Protocol 'Time-Out' immediately before incision requires active verbal agreement by the entire team verifying patient, procedure, site/side, positioning, and required implants/equipment.
CORRECT ANSWER: B) Position the patient in low Fowler's with knees flexed, cover the exposed bowel with sterile towels saturated with warm 0.9% Normal Saline, and call the surgeon immediately.
RATIONALE: Evisceration is a medical emergency. The nurse places the patient in low Fowler's with knees bent (to reduce abdominal wall tension), covers the viscera with warm sterile saline-soaked towels, maintains NPO status, and calls the surgeon instantly.
CORRECT ANSWER: A) Patient is able to ambulate unassisted, vital signs are stable, gag reflex has returned, and a responsible adult is present to drive.
RATIONALE: Discharge criteria post-sedation require baseline vital signs, clear airway/intact gag reflex, alertness, unassisted ambulation, ability to retain fluids, and an accompanying responsible adult.
CORRECT ANSWER: B) Localized erythema extending 2 cm beyond the incision, warmth, foul-smelling purulent exudate, and temperature of 101.4°F.
RATIONALE: SSI manifestations include spreading erythema, warmth, purulent drainage, induration, localized pain, and fever (>100.4°F).
CORRECT ANSWER: B) Assist the male patient to stand at the bedside or female patient to sit on the bedside commode to attempt voiding.
RATIONALE: Anesthesia and opioids cause urinary retention. Initial nursing interventions are independent/non-invasive: positioning upright (standing/sitting commode), running water, privacy. If unsuccessful, straight catheterization per order follows.
CORRECT ANSWER: B) Massaging or rubbing the right calf muscle firmly.
RATIONALE: Never massage or compress a calf suspected of deep vein thrombosis (DVT), as mechanical manipulation can dislodge the thrombus, causing a fatal pulmonary embolism.
CORRECT ANSWER: A) Sustained maximal inspirations using an incentive spirometer 10 times per hour while awake, combined with splinted coughing.
RATIONALE: Incentive spirometry promotes alveolar expansion and surfactant production. Splinting the incision with a pillow allows effective deep breathing and coughing without incisional disruption.
CORRECT ANSWER: B) 'Tell me more about your specific concerns regarding anesthesia.'
RATIONALE: Open-ended therapeutic communication ('Tell me more…') validates the patient's feelings, encourages expression of fears, and allows the nurse to provide accurate clarification or request an anesthesia consult.
CORRECT ANSWER: B) Spinal anesthesia
RATIONALE: Spinal anesthesia is an injection into the subarachnoid space (containing CSF). Epidural anesthesia is injected into the epidural space outside the dura mater.
CORRECT ANSWER: A) Post-dural puncture (spinal) headache due to CSF leakage.
RATIONALE: A post-dural puncture headache occurs when dura is punctured, causing CSF leakage and decreased intracranial pressure. It is characteristically postural (worse upright, relieved lying flat).
CORRECT ANSWER: B) Coercing an hesitant patient into signing a surgical consent form by stating the doctor will drop them as a patient if they don't agree.
RATIONALE: Autonomy is the right of self-determination. Coercion or threatening a patient violates autonomy and invalidates legal informed consent.
CORRECT ANSWER: B) Allow the CHG solution to air-dry naturally on the skin without rinsing.
RATIONALE: CHG provides persistent cumulative antimicrobial action. It MUST NOT be rinsed off; it must be allowed to air dry naturally. Avoid contact with eyes, face, and inner ears.
CORRECT ANSWER: B) Bathing the patient 2-3 times per week with lukewarm water and a no-rinse, pH-balanced hydrating cleanser, followed by topical emollients.
RATIONALE: Frequent full baths with hot water and harsh soaps strip natural epidermal lipids in older adults. Using lukewarm water, mild pH-balanced cleansers, and immediate emollient application prevents xerosis and skin tears.
CORRECT ANSWER: B) Gently retract the foreskin, cleanse the glans from meatus outward, rinse/dry, and IMMEDIATELY return the foreskin to its natural position over the glans.
RATIONALE: Failure to return the retracted foreskin causes paraphimosis (severe constriction of the glans penis, leading to edema, ischemia, and necrosis).
CORRECT ANSWER: B) Reducing oral bacterial colonization to prevent Ventilator-Associated Pneumonia (VAP) and aspiration pneumonia.
RATIONALE: Oropharyngeal secretions in bedridden/ventilated patients harbor pathogenic bacteria. Meticulous oral care significantly reduces bacterial load, preventing aspiration pneumonia and VAP.
CORRECT ANSWER: B) 'Use a warm towel/bag bath, maintain a calm unhurried demeanor, keep the patient covered for warmth, and focus on one body part at a time.'
RATIONALE: Person-centered dementia care adapts hygiene to prevent agitation: soft lighting, warmth, towel baths, distraction, washing least sensitive areas first, and respecting patient preferences.
CORRECT ANSWER: B) From the pubic symphysis downward toward the anal area (front to back).
RATIONALE: Cleansing front to back (least contaminated pubic area to most contaminated anal area) prevents contamination of the urethral meatus with intestinal E. coli bacteria, reducing UTI risk.
CORRECT ANSWER: B) Soaking feet in warm soapy water for 30 minutes daily to soften calluses, then cutting toenails rounded at the corners with clippers.
RATIONALE: Diabetics must NEVER soak feet (causes maceration and infection entry points) and must NEVER cut nails rounded or into corners (causes ingrown nails/ulcers). Nails should be filed straight across.
CORRECT ANSWER: B) Remove the gown from the uninjured left arm first, then slide the right sleeve off, threading the IV bag and tubing through the right sleeve from inside out.
RATIONALE: To maintain sterile line integrity, never disconnect IV lines to change a gown. Remove gown from non-IV arm first, then pass sleeve over IV arm, bag, and tubing from inside to outside.
CORRECT ANSWER: B) Side-lying (Sims' or lateral) position with the head turned toward the mattress and bed flat or low.
RATIONALE: Unconscious patients must be placed in a side-lying position with head turned to the side so fluids and oral secretions drain naturally out of the mouth by gravity rather than being aspirated into lungs.
CORRECT ANSWER: B) Placing a washcloth or towel in the bottom of a sink filled with cool water while brushing.
RATIONALE: Lining the sink basin with a washcloth or filling it partially with cool water cushions dentures if dropped, preventing costly fracture.
CORRECT ANSWER: B) Incontinence-Associated Dermatitis (IAD) with secondary fungal/candidal infection
RATIONALE: IAD presents as diffuse red denuded skin exposed to moisture/stool. Satellite lesions (small red papules outside the main border) indicate a secondary Candida albicans fungal infection.
CORRECT ANSWER: B) Wipe from the inner canthus outward toward the outer canthus using a clean, damp cloth section per stroke.
RATIONALE: Wiping from inner to outer canthus prevents pushing debris or microorganism-laden secretions into the nasolacrimal duct.
CORRECT ANSWER: B) A 3- to 5-minute effleurage back massage using warm lotion.
RATIONALE: Effleurage (long, smooth, gliding strokes up the spine and down the sides) promotes cutaneous circulation, relieves muscle tension, and induces relaxation.
CORRECT ANSWER: B) Inform the patient that all metallic jewelry must be removed prior to entering the MRI suite to prevent thermal injury and artifact.
RATIONALE: Metallic objects pose severe projectile and burn hazards in the strong magnetic field of an MRI and must be removed prior to scanning (a plastic retainer may replace it if needed).
CORRECT ANSWER: B) Deep skin folds (under breasts, abdominal pannus, groin, and axillae).
RATIONALE: Intertrigo is an inflammatory skin condition caused by skin-on-skin friction and trapped moisture in deep intertriginous skin folds, predisposing to fungal infection.
CORRECT ANSWER: A) 'Face washing is done first because it is the cleanest area, preventing transfer of body bacteria to the eyes and face.'
RATIONALE: Hygiene proceeds from cleanest areas to dirtiest areas to prevent cross-contamination of delicate structures like eyes and face.
CORRECT ANSWER: B) 105°F to 110°F (40.5°C to 43.3°C)
RATIONALE: Water temperature for bed baths should be comfortably warm, between 105°F and 110°F (40.5°C - 43.3°C), to prevent thermal skin injury or chilling.
CORRECT ANSWER: B) Oral Candidiasis (Thrush)
RATIONALE: Oral thrush (Candidiasis) presents as creamy white cottage-cheese-like patches on oral mucosa that reveal red bleeding surfaces when scraped.
CORRECT ANSWER: B) Closing room doors/curtains, keeping unwashed body parts covered with a bath blanket, and encouraging the patient to perform as much self-care as possible.
RATIONALE: Dignity and independence are preserved by providing privacy, exposing only the body part being cleaned, and fostering self-care.
CORRECT ANSWER: B) Assisting with toileting, washing face and hands, and providing oral hygiene to refresh the patient for breakfast.
RATIONALE: Early morning care prepares the patient for breakfast by assisting with elimination, hand/face washing, and oral care.
CORRECT ANSWER: A) Stage 1 Pressure Injury
RATIONALE: Stage 1 is defined as intact skin with localized nonblanchable erythema (does not turn white when pressed). Changes in temperature, firmness, or sensation may precede visual color changes.
CORRECT ANSWER: B) Stage 2 Pressure Injury
RATIONALE: Stage 2 is partial-thickness skin loss with exposed dermis. The wound bed is viable, pink/red, moist, and may present as an intact or ruptured serum-filled blister. Subcutaneous fat is NOT visible.
CORRECT ANSWER: B) Stage 3 Pressure Injury
RATIONALE: Stage 3 is full-thickness loss of skin in which adipose (fat) is visible in the ulcer and granulation tissue and epibole (rolled edges) are often present. Fascia, muscle, tendon, ligament, or bone are NOT exposed.
CORRECT ANSWER: B) Stage 4 Pressure Injury
RATIONALE: Stage 4 is full-thickness skin and tissue loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage, or bone.
CORRECT ANSWER: C) Unstageable Pressure Injury
RATIONALE: Unstageable pressure injury is full-thickness skin and tissue loss in which the extent of tissue damage within the ulcer cannot be confirmed because it is obscured by slough or eschar.
CORRECT ANSWER: C) Deep Tissue Pressure Injury (DTPI)
RATIONALE: DTPI is intact or nonintact skin with localized area of persistent, nonblanchable deep red, maroon, or purple discoloration, or epidermal separation revealing a dark wound bed or blood-filled blister.
CORRECT ANSWER: A) Stable, dry, adherent, intact eschar on the heels without erythema or fluctuance should NOT be debrided.
RATIONALE: Stable, dry, adherent, intact eschar on the heels serves as the body's natural (biological) cover and should not be softened or debrided unless clinical signs of infection occur.
CORRECT ANSWER: D) High risk for pressure injury
RATIONALE: Braden Scale interpretation: 19-23 = No risk; 15-18 = Mild risk; 13-14 = Moderate risk; 10-12 = High risk; <= 9 = Very high risk. A score of 11 represents High Risk.
CORRECT ANSWER: A) Serum Albumin < 3.2 g/dL (or Prealbumin < 15 mg/dL)
RATIONALE: Protein is essential for tissue repair and collagen synthesis. Serum Albumin < 3.2 g/dL or Prealbumin < 15 mg/dL signals protein-calorie malnutrition and high risk for pressure injury.
CORRECT ANSWER: B) 30 degrees
RATIONALE: Elevating the head of the bed higher than 30 degrees causes the skeleton to slide downward while skin remains fixed against sheets, creating shearing forces that tear deep capillaries.
CORRECT ANSWER: B) Every 2 hours
RATIONALE: Bedbound patients must be repositioned at least every 2 hours (q2h) to relieve pressure over bony prominences. (Chair-bound patients require repositioning every 1 hour).
CORRECT ANSWER: A) Greater trochanter and sacrum
RATIONALE: The 30-degree lateral tilted position avoids direct pressure on the sacrum posteriorly and the greater trochanter laterally.
CORRECT ANSWER: B) Place pillows under the patient's calves lengthwise to 'float' the heels completely off the mattress.
RATIONALE: Floating heels by placing pillows under calves ensures total pressure relief over calcaneus bony prominences. Donut cushions are contraindicated as they restrict blood flow.
CORRECT ANSWER: A) Reactive hyperemia blanches (turns white) when finger pressure is applied and resolves within 60-90 minutes; Stage 1 does not blanch.
RATIONALE: Reactive hyperemia is a normal physiological flush of blood returning to ischemic tissue that BLANCHES with pressure. Stage 1 erythema is NONBLANCHABLE.
CORRECT ANSWER: B) Palpating for changes in skin temperature (warmth or coolness), edema, tissue induration (firmness), and localized pain.
RATIONALE: In dark skin, nonblanchable erythema may not be visually apparent. Assessing localized warmth/coolness, induration, boggy texture, tautness, and pain is crucial.
CORRECT ANSWER: B) They concentrate pressure on surrounding blood vessels, impeding venous return and accelerating tissue ischemia in the center.
RATIONALE: Donut cushions create a ring of high pressure that restricts venous outflow and microvascular perfusion, worsening localized tissue hypoxia.
CORRECT ANSWER: B) Two surfaces rubbing against one another, stripping the superficial epidermal skin layer (e.g., dragging a patient across bedsheets).
RATIONALE: Friction is a mechanical force when skin rubs against external surfaces (sheets), removing epidermis like a 'sheet burn'.
CORRECT ANSWER: A) Every 15 minutes
RATIONALE: Chair-bound patients experience high pressure on ischial tuberosities; they should shift weight every 15 minutes and be repositioned by staff at least every 1 hour.
CORRECT ANSWER: B) Moisture macerates the skin, softening epidermal tissue and increasing susceptibility to friction and shear breakdown.
RATIONALE: Prolonged moisture softens collagen fibers (maceration), eroding skin resistance to mechanical shear and friction.
CORRECT ANSWER: C) Protecting the intact skin from friction and shear while allowing visual inspection.
RATIONALE: Transparent films are semi-permeable, occlusive, water-resistant dressings that reduce friction and allow continuous visualization of Stage 1 intact skin.
CORRECT ANSWER: A) Primary Intention
RATIONALE: Primary intention healing occurs in clean wounds with well-approximated edges (sutured or stapled), resulting in minimal tissue loss, rapid healing, and minimal scarring.
CORRECT ANSWER: B) Secondary Intention
RATIONALE: Secondary intention occurs in wounds with significant tissue loss and unapproximated edges. Healing takes longer as the wound fills with granulation tissue, forming a larger scar.
CORRECT ANSWER: C) Tertiary Intention (Delayed Primary Closure)
RATIONALE: Tertiary intention occurs when a contaminated wound is purposefully left open to drain and heal initially, then sutured closed once infection/edema subsides.
CORRECT ANSWER: C) Proliferation Phase
RATIONALE: The Proliferation Phase (days 3-24) is characterized by fibroblast activity, collagen deposition, angiogenesis, and granulation tissue formation.
CORRECT ANSWER: C) 3 weeks to 1-2 years
RATIONALE: The Maturation Phase begins around 3 weeks post-injury and continues for up to 1 to 2 years, during which collagen is reorganized and scar tissue gains tensile strength (up to 80% original).
CORRECT ANSWER: A) Serous drainage
RATIONALE: Serous exudate is clear, watery plasma derived from blood serum.
CORRECT ANSWER: B) Sanguineous
RATIONALE: Sanguineous exudate consists of large numbers of red blood cells, indicating fresh active bleeding.
CORRECT ANSWER: C) Serosanguineous
RATIONALE: Serosanguineous drainage is a mixture of clear serum and red blood cells, appearing light pink to pale red.
CORRECT ANSWER: D) Purulent
RATIONALE: Purulent drainage consists of dead white blood cells, cellular debris, and liquefied bacteria, indicating infection. It is thick, yellow/green, and foul-smelling.
CORRECT ANSWER: B) Cleanse the wound and debride slough using appropriate dressings or irrigation.
RATIONALE: RYB priorities: RED = Protect; YELLOW = Cleanse (remove slough/exudate); BLACK = Debride (remove necrotic eschar).
CORRECT ANSWER: B) By manually compressing the flexible bulb after emptying and inserting the plug to create low negative pressure.
RATIONALE: Closed suction drains (JP and Hemovac) rely on manual compression of the reservoir bulb or accordion chamber to create continuous low negative suction.
CORRECT ANSWER: B) A sterile safety pin placed through the exposed end of the drain outside the wound.
RATIONALE: A sterile safety pin is inserted through the outer portion of a Penrose drain to prevent the flexible rubber tube from retracting into the wound.
CORRECT ANSWER: B) Continuous controlled negative pressure pulls wound edges together, removes exudate/infectious material, and stimulates microvascular granulation.
RATIONALE: NPWT applies negative pressure (vacuum) to a foam dressing, removing excess fluid, reducing bacterial load, drawing wound edges together, and stimulating cell mitosis and perfusion.
CORRECT ANSWER: B) Presence of necrotic eschar/slough in the wound bed, exposed blood vessels/organs, or active wound hemorrhage.
RATIONALE: NPWT contraindications include untreated osteomyelitis, necrotic tissue/eschar, exposed arteries/veins/organs, active bleeding, or malignancy in the wound.
CORRECT ANSWER: B) Cleanse the wound thoroughly with 0.9% Normal Saline first, then press a sterile swab into viable, clean granulation tissue in a Z-pattern.
RATIONALE: To identify true pathogens rather than surface colonizers: flush wound with saline first, then rotate swab over clean, viable granulation tissue using the Levine Z-technique.
CORRECT ANSWER: B) From the cleanest area (least contaminated) to the dirtiest area (most contaminated).
RATIONALE: Irrigate from cleanest to most contaminated area to avoid flushing bacteria or debris into uninfected tissue.
CORRECT ANSWER: B) A 35 mL syringe equipped with a 19-gauge angiocatheter or needleless cannula.
RATIONALE: A 35 mL syringe with a 19-gauge catheter delivers ~8 psi of pressure—the evidence-based gold standard for effective debris removal without damaging granulation cells (safe range 4-15 psi).
CORRECT ANSWER: B) Maceration
RATIONALE: Maceration is tissue softening and breakdown resulting from prolonged exposure to excess moisture (wound exudate or urine), appearing white, boggy, and fragile.
CORRECT ANSWER: B) Hydrogel dressing
RATIONALE: Hydrogels are high-water-content polymer dressings that donate moisture to dry wound beds, soothing pain and facilitating autolytic debridement.
CORRECT ANSWER: B) Moderate to heavily exudating wounds and bleeding cavity wounds.
RATIONALE: Alginate dressings absorb up to 20 times their weight in exudate, forming a moist gel bed, and have subtle hemostatic properties for heavily exudating wounds.
