A nurse is caring for an infant who is postoperative following the placement of a ventriculoperitoneal shunt for treatment of hydrocephalus. Which of the following findings should the nurse expect?

Choice A reason: Melanoma is characterized by asymmetry, irregular borders, and variegated coloring (multiple shades of brown, black, red, or even white). These features are part of the "ABCDE" criteria used to identify suspicious lesions: Asymmetry, Border irregularity, Color variation, Diameter greater than 6 mm, and Evolving changes. This makes option A the correct answer because it describes the hallmark features of melanoma.

Choice B reason: A central crater with rolled borders is more typical of basal cell carcinoma, not melanoma. Basal cell carcinoma often presents as a pearly or waxy nodule with a central depression or ulceration and rolled edges. This option is incorrect because it describes a different type of skin cancer.

Choice C reason: A wart-like texture is commonly associated with squamous cell carcinoma, which can appear as rough, scaly patches or wart-like growths. This is not characteristic of melanoma, which tends to be pigmented and irregular rather than wart-like. Therefore, this option is incorrect.

Choice D reason: A firm and rubbery texture is more typical of benign dermatofibromas or other non-melanoma lesions. Melanomas are usually irregular, pigmented, and may be raised, but they are not typically described as firm and rubbery. This option is incorrect because it does not match the clinical presentation of melanoma.

Choice A reason: Electrical cords secured to the baseboards are safe because they reduce tripping hazards. Loose cords across walkways would be dangerous, but secured cords are appropriate.

Choice B reason: A computer chair with wheels that lock is safe. Locking wheels prevent the chair from rolling unexpectedly, reducing fall risk.

Choice C reason: A standard toilet seat can be a hazard for clients at risk of falls because it is low and requires significant effort to sit and stand. Raised toilet seats or grab bars are recommended to reduce strain and prevent falls. This is the correct hazard identified.

Choice D reason: Carpeted floors in the kitchen are not typically a fall hazard. In fact, carpeting can reduce slipping compared to smooth surfaces. The greater concern in kitchens is wet or greasy floors, not carpeting.
