A client diagnosed with contact dermatitis is receiving education from the nurse. Which of the following therapies will the nurse recommend to the client?

Phototherapy

Antibiotics

UV light

Avoidance

Answer and Explanation

The Correct Answer is D

Choice A Reason: This is incorrect because phototherapy is not a recommended therapy for contact dermatitis. Phototherapy involves exposing the skin to artificial light sources that emit specific wavelengths of light that can have anti-inflammatory or immunomodulatory effects. Phototherapy can be used for some skin conditions, such as psoriasis or eczema, but not for contact dermatitis.

Choice B Reason: This is incorrect because antibiotics are not a recommended therapy for contact dermatitis. Antibiotics are drugs that kill or inhibit bacteria that cause infections. Contact dermatitis is not an infection, but an allergic or irritant reaction to a substance that comes in contact with the skin. Antibiotics have no effect on contact dermatitis and may cause adverse effects or resistance.

Choice C Reason: This is incorrect because UV light is not a recommended therapy for contact dermatitis. UV light refers to ultraviolet radiation from sunlight or artificial sources that can damage DNA and cause skin cancer or aging. UV light can also worsen contact dermatitis by increasing inflammation and sensitivity to allergens or irritants.

Choice D Reason: This is correct because avoidance is the best therapy for contact dermatitis. Avoidance means identifying and avoiding the substance that causes the skin reaction. This can prevent further exposure and allow the skin to heal. The nurse can help the client by providing education on how to read labels, use protective clothing or gloves, or substitute safer products.

Correct Answer is B

Explanation

Choice A Reason: A virus is not detected by the KOH test, which is used to diagnose fungal infections of the skin, hair, or nails. A virus can be detected by other tests, such as polymerase chain reaction (PCR) or viral culture.

Choice B Reason: A fungal infection is detected by the KOH test, which dissolves the skin cells and leaves behind the fungal elements that can be seen under a microscope. A fungal infection can cause symptoms such as itching, scaling, redness, or blisters.

Choice C Reason: A bacterial infection is not detected by the KOH test, which is specific for fungi. A bacterial infection can be detected by other tests, such as gram stain or culture.

Choice D Reason: Cancer is not detected by the KOH test, which is not a screening tool for malignancy. Cancer can be detected by other tests, such as biopsy or imaging.

A. Provide written materials and visual aids B. Use American Sign Language C. Shout at the client from 6 inches away D. Speak to the client in an everyday conversational tone

Correct Answer is D

Explanation

Choice A Reason: Providing written materials and visual aids is not necessary for a client who has hearing at 15 dB, which is considered normal hearing. Normal hearing ranges from 0 to 20 dB, meaning that the person can hear sounds that are as faint as 20 dB or less.

Choice B Reason: Using American Sign Language is not appropriate for a client who has hearing at 15 dB, which is considered normal hearing. American Sign Language is a form of communication that uses hand gestures, facial expressions, and body movements to convey meaning. It is mainly used by people who are deaf or hard of hearing.

Choice C Reason: Shouting at the client from 6 inches away is not advisable for a client who has hearing at 15 dB, which is considered normal hearing. Shouting can be perceived as rude or aggressive, and can damage the hearing of both the speaker and the listener.

Choice D Reason: Speaking to the client in an everyday conversational tone is the best action for a client who has hearing at 15 dB, which is considered normal hearing. Conversational speech ranges from 40 to 60 dB, meaning that the person can hear sounds that are as loud as 60 dB or less.
