A client is receiving continuous ambulatory peritoneal dialysis since the arteriovenous (AV) graft in the right arm is no longer available for use for hemodialysis. The client has lost weight, has increasing peripheral edema, and has a serum albumin level of 1.5 g/dL (15 g/L). Which intervention is the priority for the nurse to implement?

Serum Albumin Reference Range: 3.5 to 5.5 g/dL (35 to 55 g/L)

Choice A reason: Marking an outline of the "olive-shaped" mass in the right epigastric area is not a priority nursing action. The mass is caused by hypertrophy of the pyloric sphincter, which obstructs gastric emptying and causes projectile vomiting. The mass may not be palpable in all cases.

Choice B reason: Instructing parents regarding care of the incisional area is a post-operative nursing action, not a pre-operative one. The parents will need to learn how to keep the incision clean and dry, monitor for signs of infection, and administer pain medication as prescribed.

Choice C reason: Monitoring amount of intake and infant's response to feedings is important, but not the highest priority. The infant may have difficulty feeding due to nausea, vomiting, and abdominal pain.

Choice D is correct because frequent exposure to sunlight is the most significant environmental factor when planning care for a client with osteomalacia. Osteomalacia is a condition in which the bones become soft and weak due to inadequate mineralization, often caused by vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and it can be synthesized by the skin when exposed to sunlight. The nurse should encourage the client to get at least 15 minutes of sunlight per day or take vitamin D supplements as prescribed.

Choice A is incorrect because quiet, calm surroundings are not a specific environmental factor for a client with osteomalacia. Quiet, calm surroundings may help reduce stress and promote relaxation, but they do not affect bone mineralization or vitamin D synthesis.

Choice B is incorrect because stimulating sounds and activity are not a specific environmental factor for a client with osteomalacia. Stimulating sounds and activity may help improve mood and cognition, but they do not affect bone mineralization or vitamin D synthesis.

Choice C is incorrect because cool, moist air is not a specific environmental factor for a client with osteomalacia. Cool, moist air may help relieve respiratory symptoms or allergies, but it does not affect bone mineralization or vitamin D synthesis.
