A nurse is teaching a client about carbon monoxide poisoning. Which of the following statements should the nurse identify as an indication that the client needs further instruction?

Choice A reason:

Intense pruritus: While itching (pruritus) can be a symptom of skin conditions, it is not a definitive sign of malignancy in nevi. Pruritus can be associated with benign conditions such as eczema or allergic reactions. However, if a mole starts to itch, it should be monitored closely, but it is not as strong an indicator of malignancy as irregular borders.

Choice B reason:

Irregular borders: This is a significant sign of potential malignancy in nevi. Melanomas often have uneven, notched, or scalloped borders, unlike benign moles, which typically have smooth, even borders. The irregularity in the border is due to the uncontrolled growth of melanocytes, which can spread unevenly.

Choice C reason:

Uniform pigmentation: Uniform pigmentation is generally a sign of a benign mole. Malignant moles often have multiple colors or an uneven distribution of color, which can include shades of brown, black, red, white, or blue. A mole with uniform color is less likely to be malignant.

Choice D reason:

Purulent drainage: While purulent drainage (pus) indicates an infection, it is not a typical sign of malignancy in nevi. Infections can occur in any skin lesion, but they do not specifically indicate cancer. Malignant moles are more likely to change in size, shape, or color rather than produce pus.

Choice A reason:

Removing all objects that contain latex from the client’s room is important for clients with a latex allergy, not a penicillin allergy. Latex allergies can cause severe reactions, including anaphylaxis, but this action is not relevant to a penicillin allergy.

Choice B reason:

Verifying that the client’s medication prescriptions do not include cephalosporin is crucial because cephalosporins can have cross-reactivity with penicillin. Clients with a penicillin allergy may also react to cephalosporins, so it is essential to avoid prescribing these antibiotics.

Choice C reason:

Notifying dietary services to adjust the client’s diet is not directly related to managing a penicillin allergy. Dietary adjustments are more relevant for clients with food allergies or specific dietary restrictions.

Choice D reason:

Having the client purchase a medication alert bracelet to wear in the hospital is a good practice for general safety, but it is not an immediate action the nurse should take during the admission process. The primary focus should be on ensuring that the client’s medications do not include penicillin or related antibiotics.
