The nurse is caring for a patient with ulcerative colitis and severe diarrhea.
Which nursing assessment is the highest priority?

Choice A rationale

Migraine headaches are a common comorbidity associated with fibromyalgia. Studies suggest a shared pathophysiology involving central sensitization and altered pain processing mechanisms in the central nervous system that contribute to both conditions.

Choice B rationale

Weather changes, particularly fluctuations in barometric pressure, temperature, and humidity, are frequently reported by individuals with fibromyalgia as triggers for increased pain and other symptoms like stiffness and fatigue. The exact mechanisms are not fully understood but may involve changes in tissue pressure and nerve sensitivity.

Choice C rationale

Chest pain, specifically non-cardiac chest pain, is a recognized symptom in some individuals with fibromyalgia. This pain is often musculoskeletal in origin, arising from tender points in the chest wall and surrounding muscles, and is not related to cardiac issues.

Choice D rationale

Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive issues. Unlike rheumatoid arthritis or osteoarthritis, fibromyalgia does not involve joint inflammation or structural damage to the joints. The pain is believed to originate from amplified pain signals in the brain and spinal cord.

Choice A rationale

Providing mittens might prevent scratching and subsequent skin damage, but it does not address the underlying cause of the pruritus, which is likely residual irritation from the scabies treatment or the scabies mites themselves. While preventing secondary infection from scratching is important, alleviating the itch is the priority for client comfort.

Choice B rationale

Encouraging the client to gently rub the affected area can actually worsen the pruritus. Rubbing can stimulate nerve endings in the skin, further intensifying the sensation of itching and potentially leading to skin irritation and excoriation. Gentle patting or cool compresses are generally more soothing for itchy skin.

Choice C rationale

Applying additional scabicide after the initial treatment is usually not indicated for pruritus following scabies treatment, unless there is evidence of ongoing infestation. Pruritus can persist for several weeks after successful treatment due to the inflammatory response of the skin to the dead mites and their products. Overuse of scabicides can cause further skin irritation.

Choice D rationale

Assisting the client to take a cool shower can help to relieve pruritus by causing vasoconstriction of the superficial blood vessels and reducing the release of histamine and other inflammatory mediators in the skin. The cool temperature can also have a soothing effect on the nerve endings, temporarily alleviating the sensation of itching.
