- D. Ensure that bath area is at least 85 degrees and dehumidified.
Correct Answer: A

Cellulitis can spread, however this is not related to the discussion of antibiotics.
A patient developed a severe contact dermatitis of the hands, arms, and lower legs after spending an afternoon picking strawberries. The patient states that the itching is severe and cannot keep from scratching. Which instruction will be helpful in managing the pruritus?
- A. Use cool, wet dressings and baths to promote vasoconstriction.
- B. Trim the fingernails short to prevent skin damage from scratching.
- C. Expose the areas to the sun to promote drying and healing of the lesions.
- D. Wear cotton gloves and cover all other affected areas with clothing to prevent environmental irritation.
Correct Answer: A
Rationale: Wet dressings and using Burow's solution help promote the healing process. Cold compresses may be applied to decrease circulation to the area (vasoconstriction). Short nails prevent skin damage, but not pruritus. Exposing the areas to the sun will not manage pruritus. Wearing cotton gloves may prevent environmental irritation, but will not help the existing pruritis.
The nurse is caring for a 26-year-old patient who was burned 72 hours ago. The patient has partial-thickness burns to 24% of the body surface area and begins to excrete large amounts of urine. Which action should the nurse take?
- A. Increase the IV rate and monitor for burn shock.
- B. Monitor for signs of seizure activity.
- C. Assess for signs of fluid overload.
- D. Raise the foot of the bed and apply blankets.
Correct Answer: C
Rationale: As the blood volume increases, the cardiac output increases to increase renal perfusion. The result includes diuresis. However, a great risk for the patient includes fluid overload because of the rapid movement of fluid back into the intravascular space. Burn shock occurs from hypovolemia in the first 72 hours of a burn injury. Seizures are not associated with the burn injury. Raising the foot of the bed would not be of value in this situation.
