When is isotretinoin (Accutane) indicated for the treatment of acne during adolescence?
- A. The acne has not responded to other treatments.
- B. The adolescent is or may become pregnant.
- C. The adolescent is unable to give up foods causing acne.
- D. Frequent washing with antibacterial soap has been unsuccessful.
Correct Answer: A
Rationale: Isotretinoin (Accutane) is a potent medication used for severe acne that has not responded to other treatments, such as topical medications or antibiotics. It is typically considered as a last resort due to its potential side effects and risks. Adolescents with resistant, severe acne who have not seen improvement with other therapies may be good candidates for isotretinoin treatment. It is important for the prescribing healthcare provider to carefully assess the severity of the acne and weigh the benefits against the potential risks before initiating isotretinoin therapy.

- A. Wash the area with soap and warm water
- B. Leave the skin alone until it is clear
- C. Apply a cream or lotion to the area

Avoiding creams or lotions may lead to dryness and further discomfort.

As the nurse cares for a patient with angioedema, differs from urticaria in that angioedema is characterized by which of the following?
- A. Angioedema is more pruritic.
- B. Angioedema has small, fluid-filled vesicles
- C. Angioedema has a deeper and more that crust.
- D. Angioedema lasts a shorter time.
Correct Answer: C
Rationale: Angioedema differs from urticaria in that it involves deeper layers of the skin and subcutaneous tissue compared to urticaria, which affects the upper layers of the skin. This deeper involvement in angioedema can lead to swelling that appears as large, raised areas that often have a deeper hue compared to the surrounding skin. Angioedema does not typically involve small, fluid-filled vesicles like urticaria, and it is not necessarily more pruritic. Additionally, angioedema tends to last longer than urticaria, which is why option D is not accurate.
