Basal cell carcinoma has a high rate of metastasis: Basal cell carcinoma is the most common form of skin cancer and grows slowly with a very low tendency to metastasize. It usually remains localized and rarely spreads to distant tissues. Having a high rate of metastasis provides inaccurate information during patient education.

Tanning bed use should be limited to once a week: Tanning beds emit ultraviolet (UV) radiation, which significantly increases the risk of skin cancer. Even occasional exposure to artificial UV radiation can damage DNA in skin cells and increase cancer risk. Health education should emphasize avoiding tanning beds entirely rather than suggesting a “safe” frequency.

A family history of squamous cell carcinoma is a risk factor: Squamous cell carcinoma is more strongly associated with cumulative ultraviolet exposure, chronic skin damage, and environmental factors such as prolonged sun exposure. While genetic predisposition may play a minor role in some cancers, family history is not considered a primary risk factor.

You've been bitten by a vector insect such as a tick: Vector insects such as ticks are responsible for transmitting certain infections like Lyme disease or Rocky Mountain spotted fever. Shingles is not transmitted through insect bites and does not involve a vector in its pathogenesis. The condition results from reactivation of a virus already present in the body.

The toxins from a bacterial infection are making you ill: Shingles is not caused by bacteria or bacterial toxins. It is a viral condition related to the varicella-zoster virus, which initially causes chickenpox. Bacterial toxins typically produce systemic toxic responses in illnesses such as food poisoning or certain severe bacterial infections, which is not the mechanism involved in shingles.

You're having an antibody response to a disease: Antibody production is part of the immune system’s normal defense against infections, but it does not explain the underlying cause of shingles. The disease occurs when the virus that previously caused chickenpox remains dormant in nerve ganglia and later becomes reactivated.

A client who has serosanguineous drainage from the wound: Serosanguineous drainage is a mixture of clear serous fluid and small amounts of blood, commonly seen in the early stages of wound healing. It usually appears thin and pink in color and reflects normal inflammatory processes after tissue injury. This type of drainage alone does not indicate infection.

A client who has urticaria and itching around the wound: Urticaria and itching are more commonly associated with allergic reactions or hypersensitivity responses rather than infection. These symptoms may occur due to contact with adhesives, topical medications, or dressing materials used in wound care. While uncomfortable, they do not indicate bacterial invasion.

A client who has a large brown scab over the wound: The presence of a scab represents dried blood and exudate forming a protective crust over the wound surface. This natural barrier protects the underlying tissue during the healing process and is commonly seen in superficial wounds. Scabs are not considered a direct sign of infection.

Infection control: First-degree burns involve only the epidermal layer of the skin and usually present with redness, tenderness, and mild swelling without blister formation. Because the skin barrier remains largely intact, the risk of infection is relatively low compared with deeper burns. Infection control remains important but is not the primary concern for superficial burns.

Altered body image: Altered body image can occur with visible skin injuries, particularly if burns affect exposed areas such as the face or arms. However, first-degree burns typically heal within several days without scarring or long-term cosmetic changes. Psychological concerns related to appearance are therefore not the immediate priority in the acute stage of injury.

Fluid resuscitation: Fluid resuscitation is typically required for more severe burns, such as second-degree or third-degree burns that involve large body surface areas and significant damage to the dermis. First-degree burns do not cause substantial fluid loss or capillary leakage. Therefore, aggressive fluid replacement is not usually necessary in this situation.

Stage 2: Stage 2 pressure injuries involve partial-thickness loss of skin with exposure of the dermis. They often appear as a shallow open ulcer with a red or pink wound bed or may present as an intact or ruptured blister. The wound bed must be visible to determine the depth of tissue damage, a wound covered by eschar cannot be classified as stage 2.

Stage 4: Stage 4 pressure injuries involve full-thickness tissue loss with exposed or directly palpable structures such as muscle, tendon, cartilage, or bone. The wound base must be clearly visible to confirm this depth of damage. When thick eschar covers the wound bed, the actual depth of tissue destruction cannot be determined, making stage 4 classification inappropriate.

Stage 1: Stage 1 pressure injuries are characterized by intact skin with non-blanchable erythema, typically appearing as persistent redness over a bony prominence. There is no open wound and no tissue loss at this stage. The presence of eschar covering the wound bed indicates significant tissue necrosis and confirms that the injury is far more advanced than stage 1.

Ulcers: Ulcers are deep, open lesions that extend through the skin and may involve the dermis or deeper tissues. They are commonly associated with conditions such as pressure injuries, vascular insufficiency, infections, or severe inflammatory skin diseases. Acne typically presents with superficial inflammatory lesions rather than deep ulcerative tissue destruction.

Vesicles: Vesicles are small, fluid-filled blisters that contain clear serous fluid and are commonly associated with viral infections such as herpes simplex or varicella. They may also occur in allergic or inflammatory conditions like contact dermatitis. Acne lesions generally contain pus rather than clear fluid, making vesicles inconsistent with the typical presentation.

Wheals: Wheals are transient, raised areas of skin edema often associated with urticaria or allergic reactions. They usually appear suddenly, are intensely pruritic, and resolve within hours as the allergic response subsides. Acne lesions persist longer and involve follicular inflammation rather than the temporary dermal swelling seen in wheals.

The client has large, blistered areas over the legs: Large blisters are typical of partial-thickness (second-degree) burns, where the epidermis and part of the dermis are damaged. Although these burns are painful and require appropriate wound care and fluid management, they do not immediately threaten airway or breathing. Therefore, they are not the most urgent finding.

The client has decreased sensation over the burn areas: Decreased sensation can occur in deep partial-thickness or full-thickness burns due to destruction of nerve endings in the affected tissue. While this finding helps determine the depth and severity of the burn injury, it does not represent an immediate life-threatening complication.

The client has edema at the burn site: Localized swelling around a burn area is expected because inflammatory mediators increase capillary permeability, allowing fluid to move into surrounding tissues. Edema is a common response to tissue injury and typically develops during the inflammatory phase of burn trauma. It is not as urgent as signs of respiratory compromise.

1800: The medication has a half-life of 2 hours, meaning half of the drug amount is eliminated every 2 hours. At 4:00 pm the client receives 400 mg, and after the first half-life at 6:00 pm the amount remaining would be 200 mg. Since the question asks when only 100 mg remains, 6:00 pm occurs too early in the elimination process.

1600: 4:00 pm is the exact time the medication is administered, meaning the full 400 mg dose is still present in the system. Drug elimination has not yet occurred because the first half-life period has not passed. Therefore, the amount of medication in the body at this time remains unchanged.

1400: 2:00 pm occurs before the medication was given, making it impossible for any portion of the drug to already be present in the client’s system at that time. Drug concentration calculations must always begin from the time of administration, which in this scenario is 4:00 pm.

Lice: Lice infestation is caused by parasitic insects that live on the scalp, body, or pubic hair and feed on human blood. The most common manifestation is intense itching of the scalp or affected hair-bearing areas with visible nits attached to hair shafts. Lice do not produce burrows or wavy lines on the skin, particularly between the fingers.

Ringworm: Ringworm, also known as tinea corporis, is a fungal infection of the skin characterized by circular, red, scaly lesions with a raised border and central clearing. The lesions typically appear ring-shaped and may be mildly itchy. This infection does not produce thin, wavy burrow-like lines in the skin or commonly occur between the fingers in that pattern.

Psoriasis: Psoriasis is a chronic autoimmune inflammatory skin condition characterized by thick, erythematous plaques covered with silvery scales. The lesions commonly appear on the scalp, elbows, knees, and lower back. Although itching may occur, psoriasis does not cause burrows or wavy lines between the fingers, which are more typical of parasitic infestation.

Assess bowel sounds in all four quadrants: Assessment of bowel sounds is important during the acute or rehabilitation phases of burn care to monitor gastrointestinal function. However, it is not part of emergent care immediately following a burn, as priority interventions focus on stopping the burn, maintaining airway, and stabilizing vital signs.

Perform passive ROM and encourage active ROM: Range-of-motion exercises are primarily indicated in the rehabilitative phase to prevent contractures and maintain mobility. During the emergent phase, the priority is to prevent further tissue damage and stabilize the patient, not to initiate ROM exercises.

Maintain nutritional status by force feeding: Nutritional support is crucial in burn care because metabolism increases during the healing process, but this intervention is part of the acute or recovery phase. Emergent care focuses on immediate life-saving actions rather than long-term nutritional management.
