The client has been diagnosed with a stage 4 pressure ulcer with tunneling. Which intervention should the nurse implement when instructed to apply a medicated rope dressing to the wound?

Correct Answer: C

Rationale: Inserting a medicated rope dressing into the tunnel with a sterile cotton swab promotes healing. Questioning is unnecessary, topical anesthetics aren't used, and saline precedes, not follows, dressing.

Correct Answer: B

Rationale: Interleukin-2 is used as an adjuvant immunotherapy for malignant melanoma.

Correct Answer: A

Rationale: Keratoacanthomas originate from the hair follicle.

Correct Answer: B

Rationale: For a flap to survive, it must have a viable blood supply.

Correct Answer: A

Rationale: Grain intake should include at least six servings daily. To maintain a healthy weight and reduce incidence of cardiovascular disease, fat intake should not exceed 30 % of the daily intake. Folic acid intake should be at 400 mg daily, not 200 mg. Iron is a vital ingredient in the daily diet; 18 mg daily is reflective of the desired amount, and limiting it below 21 mg is unnecessary for constipation prevention, which is better managed by fluid and fiber intake.
