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

Choice A rationale

Maintaining a recommended body weight is crucial for managing osteoarthritis as excess weight places additional stress on weight-bearing joints like the hips and knees, accelerating cartilage breakdown and increasing pain. Reducing this mechanical stress can slow the progression of the disease and alleviate symptoms. A healthy Body Mass Index (BMI) is generally considered to be between 18.5 and 24.9 kg/m².

Choice B rationale

Applying ice to the joint before exercising is generally not recommended for osteoarthritis. While ice can help reduce inflammation and pain after exercise or during acute flares, applying it before exercise can stiffen the joint and potentially hinder movement, increasing the risk of injury. Heat application is often preferred before exercise to warm up the muscles and tissues around the joint, improving flexibility.

Choice C rationale

Reducing the amount of purine in the diet is a primary recommendation for managing gout, a type of arthritis caused by the buildup of uric acid crystals in the joints. Purines are substances found in certain foods that break down into uric acid. Osteoarthritis, however, is a degenerative joint disease not directly related to purine metabolism or uric acid levels.

Choice D rationale

There is insufficient scientific evidence to support the use of Echinacea for managing joint pain associated with osteoarthritis. Echinacea is an herb primarily known for its potential immune-boosting properties and is often used for colds and flu. Its efficacy in treating the underlying mechanisms or symptoms of osteoarthritis has not been established through rigorous clinical trials.

Choice A rationale

Elevating the affected leg promotes venous return and lymphatic drainage, which helps to reduce swelling and inflammation associated with cellulitis. Gravity assists in the removal of excess fluid from the interstitial spaces, thereby alleviating pressure and promoting healing.

Choice B rationale

Applying fresh ice packs every 4 hours can provide some pain relief and vasoconstriction, potentially reducing inflammation in the initial stages of cellulitis. However, heat is generally preferred after the acute inflammatory phase to promote circulation and healing. Frequent, prolonged ice application might impede blood flow.

Choice C rationale

While rest is important for healing, enforcing strict bedrest for 3 days might not be necessary and could increase the risk of complications such as deep vein thrombosis. Moderate activity with elevation is usually recommended to promote circulation without exacerbating the infection.

Choice D rationale

Cellulitis is a deep infection of the skin and subcutaneous tissues, typically caused by bacteria entering through a break in the skin. Applying topical antibiotic ointment is unlikely to reach the deeper infected tissues and is not the primary treatment. Systemic antibiotics are required to treat cellulitis effectively.
