Which of the following patients should be screened carefully before electrolysis?

Screening patients carefully before performing electrolysis is essential to ensure their safety and the effectiveness of the treatment. Each of the groups mentioned presents specific considerations that warrant thorough screening.

Pregnant women should be screened because hormonal changes can affect skin sensitivity and healing processes. Additionally, the safety of various electrolysis methods during pregnancy may not be fully established, thus requiring extra caution.

Individuals with autoimmune disorders can have altered immune responses, which may complicate skin healing or increase the risk of adverse reactions after electrolysis. Certain autoimmune conditions can also cause skin hypersensitivity, necessitating careful evaluation before treatment.

Patients with skin conditions are another important group to consider during screenings. Conditions such as eczema, psoriasis, or other dermatological issues can impact the skin's integrity and its ability to tolerate the electrolysis process. Electrolysis performed on compromised skin may lead to complications such as irritation or infection.

Since all these groups require careful consideration and individualized approaches prior to undergoing electrolysis, the choice indicating that all of the above categories should be screened carefully is clearly the most comprehensive and correct answer.
