In assessing a client with ulcers on the lower extremity, which findings indicate that the ulcers are likely to be of venous, rather than arterial, origin?

Choice A reason: Weight gain of 2 pounds (0.91 kg) in one day is a sign of fluid retention, which occurs in SIADH due to excessive secretion of antidiuretic hormone (ADH). ADH causes the kidneys to reabsorb water and reduce urine output, leading to hyponatremia and hypervolemia.

Choice B reason: Fremitus over the chest wall is a sign of increased vibration or air movement in the lungs, which can indicate pneumonia, bronchitis, or pleural effusion. These are not related to SIADH, but may be complications of head injury or fluid overload.

Choice C reason: Serum sodium of 150 mEq/L (150 mmol/L) is a sign of hypernatremia, which is a high level of sodium in the blood. This is the opposite of what happens in SIADH, where sodium levels are low due to dilution by excess water.

Choice D reason: Urine specific gravity of 1.004 is a sign of diluted urine, which indicates low concentration of solutes in the urine. This is also the opposite of what happens in SIADH, where urine is concentrated and has a high specific gravity.

Choice A reason: Returning for periodic liver function studies is an important instruction for a client with gouty arthritis who is taking colchicine and indomethacin. These medications can cause liver toxicity, which can manifest as jaundice, abdominal pain, nausea, vomiting, and dark urine. The nurse should advise the client to monitor for these signs and symptoms, and to have regular blood tests to check the liver enzymes and function.

Choice B reason: Massaging joints to relax muscles and decrease pain is not a recommended instruction for a client with gouty arthritis who has acute inflammation of the right ankle and great toe. Massage can increase the blood flow and pressure to the affected joints, which can worsen the pain and swelling. The nurse should advise the client to avoid touching or moving the inflamed joints, and to apply ice packs or cold compresses to reduce the inflammation.

Choice C reason: Limiting use of mobility equipment to avoid muscle atrophy is not a necessary instruction for a client with gouty arthritis who has acute inflammation of the right ankle and great toe. Mobility equipment such as crutches, walkers, or canes can help the client to ambulate safely and comfortably, and to prevent further injury or damage to the affected joints. The nurse should encourage the client to use mobility equipment as needed, and to perform gentle range of motion exercises when the inflammation subsides.

Choice D reason: Substituting natural fruit juices for carbonated drinks is not a helpful instruction for a client with gouty arthritis who is taking colchicine and indomethacin. Fruit juices can contain high amounts of fructose, which can increase the uric acid levels in the blood and trigger gout attacks. Carbonated drinks are not a major risk factor for gout, unless they contain high-fructose corn syrup or alcohol. The nurse should advise the client to drink plenty of water, and to avoid foods and beverages that are high in purines, such as organ meats, seafood, beer, and wine.
