Free Wound Care Certification Trivia Question and Answer — Questions and Answers

Question 1: An illustration of a wound that most likely may see secondary healing is

an infected wound (Correct answer)
a clean laceration
a split-thickness graft
an extensive contaminated dog bite wound

Correct answer: an infected wound

Secondary intention healing occurs when a wound is left open to heal by granulation, contraction, and epithelialization, rather than being surgically closed. This method is preferred for wounds with significant tissue loss, heavy contamination, or infection, as it allows for drainage and reduces the risk of abscess formation. An infected wound is a prime example where primary closure would trap bacteria and worsen the infection, making secondary healing the safer choice.

Question 2: What is the shortest amount of time that an EMLA cream (Eutectic Mixture of Local Anesthetics) should be applied before initiating a dressing change in order to relieve pain?

10 minutes
15 minutes
35 minutes
60 minutes (Correct answer)

Correct answer: 60 minutes

EMLA cream, a topical anesthetic, requires sufficient time to penetrate the skin layers and effectively numb the nerve endings. For optimal pain relief during procedures like dressing changes, it is generally recommended to apply the cream for at least 60 minutes (1 hour) before initiating the intervention. This ensures adequate absorption and therapeutic effect, minimizing patient discomfort.

Question 3: Which of the following is the appropriate intervention when a wound has a damaged matrix and cell debris that prevents healing?

Antimicrobials
Negative pressure wound therapy
Debridement (Correct answer)
Moisture-balancing dressings

Correct answer: Debridement

Debridement is the essential intervention for wounds with damaged matrix and cell debris, as non-viable tissue and foreign material impede the healing process. Removing this necrotic tissue and debris promotes the formation of healthy granulation tissue, reduces the bacterial load, and allows the wound to progress through the normal stages of healing. Without debridement, chronic inflammation and infection can persist, preventing wound closure.

Question 4: What should be considered when assessing a patient's nutritional status is the typical daily caloric requirement for effective wound healing?

1500 to 3500 cal/day (Correct answer)
2000 to 3000 cal/day
1000 to 1400 cal/day
3000 to 4000 cal/day

Correct answer: 1500 to 3500 cal/day

Effective wound healing is an energy-intensive process that significantly increases the body's metabolic demands. To support tissue repair, collagen synthesis, and immune function, patients require an adequate caloric intake. A typical daily caloric requirement for optimal wound healing ranges from 1500 to 3500 calories, depending on the wound size, severity, and individual patient factors.

Question 5: Which of the following therapies is recommended as a first line of treatment for weepy, red, itchy atopic dermatitis?

Hypoallergenic creams
Topical antihistamine
Topical antibiotic
Wet aluminum acetate compresses (Correct answer)

Correct answer: Wet aluminum acetate compresses

Wet aluminum acetate (Burow's solution) compresses are a recommended first-line treatment for acute, weeping, red, and itchy atopic dermatitis. The solution has astringent and antiseptic properties that help to dry out the oozing lesions, reduce inflammation, and provide a soothing effect. This helps to alleviate itching and redness, promoting comfort and healing in the affected skin.

Question 6: Which of the following complications could arise if a patient is positioned prone with their head tilted laterally to ease strain on their hips and spine?

Increased intracranial pressure and increased intraocular pressure
Decreased cerebral circulation and ocular damage (Correct answer)
Injury to the peroneal nerve as well as dislocation of the hip and stress on the lower back and pelvis
Diaphragm displaced anteriorly by abdominal viscera resulting in decreased functional residual capacity, especially in the elderly

Correct answer: Decreased cerebral circulation and ocular damage

When a patient is positioned prone with their head tilted laterally, there is a risk of compressing the carotid or vertebral arteries in the neck. This compression can lead to decreased cerebral circulation, potentially causing brain ischemia. Additionally, direct pressure on the eye or inadequate padding can result in ocular damage, such as corneal abrasions, retinal ischemia, or even vision loss.

Question 7: The skin layer that lies between the stratum corneum and the stratum granulosum is known as the _________ . It is made up of translucent cells that are exclusively found on the soles of the feet and the palms of the hands.

Stratum corneum
Dermis
Stratum lucidum (Correct answer)
Stratum basale

Correct answer: Stratum lucidum

The stratum lucidum is a thin, clear, and translucent layer of dead skin cells found exclusively in the thick skin of the palms of the hands and soles of the feet. It is located between the stratum corneum and the stratum granulosum. This layer provides an additional protective barrier in areas subjected to high friction and pressure.

Question 8: A 35-year-old man walks into the emergency room with a hole in his left foot where he stepped on a rusty nail. His last tetanus shot was when he was a child, which caused a severe allergic reaction and a long stay in the hospital. Which of these statements is true about this patient's tetanus immunization?

Give tetanus immunoglobulin and toxoid.
Give neither tetanus toxoid nor immunoglobulin because he has had an allergic reaction in the past.
Give tetanus toxoid.
Give tetanus immunoglobulin. (Correct answer)

Correct answer: Give tetanus immunoglobulin.

For a patient with a tetanus-prone wound and a documented history of a severe allergic reaction to tetanus toxoid, active immunization with the toxoid is contraindicated. In such cases, passive immunity is provided by administering tetanus immunoglobulin (TIG). TIG provides immediate, short-term protection against tetanus toxin without triggering an allergic response to the toxoid itself.

Question 9: A 5-year-old boy's mother takes him to the emergency room for a forehead injury. On the icy sidewalk, he slid and banged his head, she said. No unconsciousness. The child is aware and active. He has a 3-cm hairline-crossing forehead laceration. What is the best way to close the wound on this patient?

Close with Steri-Strips
Close with interrupted sutures (Correct answer)
Shave the hair surrounding the laceration and close with interrupted sutures
Close with staples

Correct answer: Close with interrupted sutures

For a 3-cm laceration on a child's forehead, interrupted sutures are the best choice for closure. They allow for precise approximation of the wound edges, which is crucial for achieving a good cosmetic outcome on the face. Interrupted sutures also provide strong closure and allow for individual adjustment of tension, accommodating for potential swelling or movement.

Question 10: A 15-year-old girl comes to the emergency room with a cut on her left index finger. She hurt herself when her friend closed the car door on her by accident. She has a half-circle cut on the back of her left second finger, just past the distal interphalangeal (DIP) joint. Sensation is still there after the cut. The DIP joint can still move as it should. The patient wants to be a hand model in the future, so he or she is very worried about how the surgery will look. Which of the following would be the best way to put this patient to sleep?

A digital block at the base of the proximal phalanx with 3 cc of lidocaine (Correct answer)
Local infiltration through the wound margins with 3 cc of lidocaine with epinephrine
Application of a tourniquet to control bleeding and irrigation of the wound with 3 cc of lidocaine
Local infiltration through the wound margins with 3 cc of lidocaine

Correct answer: A digital block at the base of the proximal phalanx with 3 cc of lidocaine

A digital block at the base of the proximal phalanx provides effective and complete anesthesia to the entire finger distal to the injection site. This method is superior to local infiltration directly into the wound margins, as it avoids distorting the delicate tissue of the finger, which is crucial for precise wound repair and achieving an optimal cosmetic outcome, especially for a patient concerned about future appearance.

Question 11: A woman who is 20 years old comes to the emergency room with a cut on her lower lip. The patient says she fell forward when her heel got stuck in a storm drain. She also has some small cuts on her face and a 3 cm-deep cut on the inside of her lower lip. You plan to close the cut to stop the bleeding and keep food from getting stuck. Which of the following materials for a suture would be best for this patient?

5-0 absorbable chromic gut (Correct answer)
6-0 nylon
2-0 nylon
1-0 absorbable chromic gut

Correct answer: 5-0 absorbable chromic gut

For intraoral lacerations, such as a deep lower lip cut, absorbable sutures are preferred because they do not require removal, minimizing patient discomfort and follow-up visits. 5-0 absorbable chromic gut is an appropriate choice as it provides sufficient tensile strength for mucosal healing and is well-suited for delicate tissue closure in the oral cavity, ensuring proper wound approximation and reducing the risk of food entrapment.

Question 12: A 55-year-old man comes to the emergency room for stitches. A piece of glass cut his right calf when he was on vacation in Jamaica two days ago. The cut was 4 cm long. At that time, the cut was cleaned, an x-ray was taken to check for a foreign object, and it was fixed. At the moment, the edges of the wound are healing well and there is no redness or drainage from the wound. What is the best management step to take next?

Have the patient return in 14 days for suture removal.
Have the patient return in 3 days for suture removal.
Remove the sutures then replace them to prevent infection.
Have the patient return in 8 days for suture removal. (Correct answer)

Correct answer: Have the patient return in 8 days for suture removal.

The timing of suture removal depends on the wound location and the tension on the skin. For wounds on the extremities, such as the calf, sutures are typically left in place longer than on the face to allow for adequate tensile strength development and reduce the risk of dehiscence. An 8-day interval is an appropriate timeframe for suture removal on the calf, balancing healing with minimizing track marks.

Question 13: After an accident, a 29-year-old man comes to the ED with the cut shown below. There are no broken teeth, and he has tetanus. After an accident, a 27-year-old man comes to the ED with the cut shown below. There are no broken teeth, and he is up to date on his tetanus shot. What are the best steps for management to take next? <br> <br> (Reproduced, with permission, from Knoop KJ, Stack LB, Storrow AB. Atlas of Emergency Medicine. New York, NY: McGraw-Hill, 2002: 162.)

Infiltration of local anesthesia into the lip and then approximation of the vermilion border
Infraorbital nerve block and then approximation of the vermilion border (Correct answer)
Infiltration of the lip with local anesthesia, closure of dermis and mucosal defects, and then approximation of the vermilion border
Infraorbital nerve block and closure of mucosal defects before the approximation of the vermilion border

Correct answer: Infraorbital nerve block and then approximation of the vermilion border

For lip lacerations, especially those involving the vermilion border, an infraorbital nerve block (for the upper lip) or a mental nerve block (for the lower lip) provides superior anesthesia compared to local infiltration. This approach avoids distorting the delicate lip anatomy with anesthetic fluid, which is crucial for precise alignment and approximation of the vermilion border, ensuring an optimal cosmetic outcome. Approximating the vermilion border accurately is the critical first step in closure.

Question 14: A 45-year-old woman comes to the emergency room with a deep dog bite on her left forearm. The dog is well-vaccinated. Which of the following is true about how to treat wounds from animal bites?

Irrigate the wound thoroughly and place deep sutures to prevent infection.
Infection after dog and cat bites is rare.
Dog-bite infections are most commonly secondary to Pasteurella multocida.
Delayed primary closure can be used for bite wounds. (Correct answer)

Correct answer: Delayed primary closure can be used for bite wounds.

Animal bite wounds carry a high risk of infection due to polymicrobial contamination and crush injury. Therefore, immediate primary closure is often avoided. Delayed primary closure is a suitable approach where the wound is thoroughly cleaned and debrided, then left open for 24-72 hours to observe for signs of infection. If no infection develops, the wound can then be safely closed, balancing infection prevention with cosmetic considerations.

Question 15: A 28-year-old man comes to the emergency department with a wound on his lower left leg. He says he hurt his left calf while pulling branches out of a flooded creek in his back yard. He says that the wound was made while his legs were in the water. When the puncture wound is looked at, it is 1 cm in diameter, several centimeters deep, and has redness around it. After cleaning the wound with water, you find a splinter in the wound. How should management proceed?

Close the wound with 4-0 nylon.
Radiograph to map the exact location of the foreign body.
Remove the splinter. (Correct answer)
Dress the wound with a sterile bandage and treat with a fluoroquinolone.

Correct answer: Remove the splinter.

The immediate priority for a visible foreign body in a wound, especially one causing redness and inflammation, is its removal. Leaving the splinter in place would act as a persistent source of irritation, inflammation, and a nidus for infection, significantly impeding wound healing. Once removed, the wound can be thoroughly cleaned and managed appropriately.

Question 16: A 25-year-old woman comes to the ED with a small, 2-cm cut in the middle of her forehead. You clean the wound and put a bandage on it. The patient wants to be an actress and is worried about how her looks will change over time. She wants detailed instructions on how to care for a wound. Which of the following is a good way to tell someone how to care for a wound?

The wound should not be washed until sutures are removed.
Avoid direct sun exposure while the wound is healing. (Correct answer)
Appearance of the scar at suture removal will be the final cosmetic outcome.
Sutures should be removed in 7 to 10 days.

Correct answer: Avoid direct sun exposure while the wound is healing.

Protecting a healing wound and newly formed scar from direct sun exposure is crucial for achieving the best cosmetic outcome. Ultraviolet (UV) radiation can cause hyperpigmentation (darkening) of the scar, making it more noticeable and potentially permanent. Patients should be advised to avoid direct sun exposure or use sunscreen and protective clothing for at least 6-12 months post-injury to minimize scar discoloration.
