A nurse is reviewing the BUN result of a client who is taking cyclosporine following a kidney transplant. Which of the following laboratory studies should the nurse recognize as another renal function study that should be monitored?

Choice A reason: Adding salt to season foods can irritate oral sores in AIDS patients, often caused by candidiasis or herpes. Salt exacerbates pain and delays healing, making this instruction harmful and inappropriate for managing oral discomfort in this population.
Choice B reason: Rinsing with alcohol-based mouthwash worsens oral soreness, as alcohol irritates mucosal lesions common in AIDS. Non-alcohol, antiseptic, or saline rinses are preferred to promote comfort and healing, making this instruction incorrect and potentially painful.
Choice C reason: Eating hot foods can aggravate oral sores, increasing pain and delaying healing in AIDS patients with mucosal damage. Lukewarm or cool foods are better tolerated, making this instruction inappropriate and counterproductive for managing the client’s symptoms.
Choice D reason: Using ice chips numbs the mouth, reducing pain from oral sores during eating for AIDS patients. This non-invasive, soothing intervention is safe and effective, aligning with comfort-focused care for mucosal lesions, making it the correct instruction.

Choice A reason: Using gauze to cover an infant’s IV site obscures visualization, delaying detection of infiltration or infection. Transparent dressings are preferred, as infants’ small veins are prone to complications. Gauze increases risk by hiding signs like swelling, critical for early intervention in pediatric IV management.
Choice B reason: Monitoring an IV site every 8 hours is inadequate for infants, who need hourly checks due to small vein fragility and high infiltration risk. Frequent assessment detects complications like phlebitis or extravasation early, ensuring vascular integrity and preventing tissue damage in pediatric patients.
Choice C reason: Inserting an IV in the foot is less preferred, as scalp or hand veins are more accessible and stable in infants. Foot IVs risk dislodgement from movement and may impair circulation, increasing complications like tissue damage, making this a suboptimal choice for IV placement.
Choice D reason: A 24-gauge catheter is ideal for infants, as their small veins require smaller needles to minimize trauma and infiltration. This size ensures adequate fluid or medication delivery while reducing vascular damage, aligning with pediatric IV guidelines for safe and effective venous access.
