A nurse in a mental health clinic receives a request from a client who is undergoing psychotherapy to obtain a copy of the therapist’s notes.

Cyanosis is a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is more difficult to detect in people who have dark skin, so the nurse should look for cyanosis in areas where the skin is thinner and the blood supply is richer, such as the palms of the hands, the lips, the gums, and around the eyes.

These areas are less affected by melanin, the pigment that gives skin its color.

Choice A is wrong because an area of trauma may have bruising or inflammation that can mask cyanosis.

Choice B is wrong because the sacrum is not a good site to assess for cyanosis in any skin tone, as it is prone to pressure ulcers and poor circulation.

Choice C is wrong because the shoulders are not a mucous membrane and may have more melanin than other areas of the body.

The correct answer is choice C. Taking a hot shower in the morning can help decrease stiffness and improve joint mobility for people with rheumatoid arthritis. This is one of the self-management strategies that can reduce pain and disability.

Choice A is wrong because applying cold packs directly on the skin of the affected joints can cause vasoconstriction and increase inflammation.

Cold therapy should be used with caution and with a barrier between the skin and the ice pack.

Choice B is wrong because biological response modifiers are not used to prevent infection, but to reduce inflammation and slow down joint damage in rheumatoid arthritis.

These medications can actually increase the risk of infection by suppressing the immune system.

Choice D is wrong because clustering physical activities during the day can cause fatigue and joint stress for people with rheumatoid arthritis.

It is better to pace activities throughout the day and take frequent breaks to rest the joints.

Normal ranges for rheumatoid arthritis are based on the disease activity score (DAS), which measures the number of swollen and tender joints, the level of inflammation in the blood, and the patient’s global assessment of health. A DAS below 2.6 indicates remission, a DAS between 2.6 and 3.2 indicates low disease activity, a DAS between 3.2 and 5.1 indicates moderate disease activity, and a DAS above 5.1 indicates high disease activity.
