A client with cancer is receiving chemotherapy with a known vesicant. The client's IV has been in place for 72 hours. The nurse determines that a new IV site cannot be obtained, and leaves the present IV in place. Which is the greatest clinical risk related to this situation?

A. Dry mucosal membranes. While dry mucous membranes can indicate dehydration, they are not a definitive indicator of malnutrition. Malnutrition is assessed through body weight, BMI, and lab values such as albumin and prealbumin.
B. Weight of 227 pounds (103 kg). A high body weight does not indicate malnutrition. Some individuals with obesity can still be malnourished due to poor nutrient intake, but weight alone is not the best diagnostic indicator.
C. Body mass index (BMI) of 17 kg/m². A BMI below 18.5 kg/m² is classified as underweight, and a BMI of 17 kg/m² indicates malnutrition. BMI is a standard measure used to assess nutritional status and underweight conditions.
D. Decrease in the appetite. A decreased appetite (anorexia) can contribute to malnutrition, but it is a symptom, not a definitive diagnostic indicator. Some individuals with poor appetite may still maintain an adequate nutritional status.

A. Immobility. The client requires a walker for mobility and reports difficulty repositioning in bed. Limited mobility increases the risk of pressure injuries due to prolonged pressure on certain areas, reducing blood flow and oxygen delivery to the skin.
B. Obesity. The client has a history of moderate obesity, which increases skin friction, moisture retention, and difficulty with self-care. Excess weight places additional pressure on bony prominences, elevating the risk of pressure ulcers.
C. Inadequate nutritional intake. The client has a poor appetite and decreased oral intake, which can lead to protein and nutrient deficiencies. Poor nutrition impairs skin integrity and delays wound healing, further increasing the risk of pressure injuries.
D. Incontinence. The client wears an incontinence brief due to occasional urinary and fecal accidents. Constant exposure to moisture from urine and stool can break down the skin barrier, making it more susceptible to infections and pressure injuries.
E. Decreased sensory perception. The client reports neuropathy in both hands and lower legs, reducing sensation. Impaired sensation can prevent the recognition of pressure, pain, or injury, leading to delayed intervention and increased risk of skin breakdown.
F. Coarse lung sounds. While coarse lung sounds may indicate respiratory congestion or infection, they do not directly contribute to skin injury risk. This factor is less relevant compared to others affecting skin integrity.
G. Diabetes mellitus. The client has poorly controlled type 1 diabetes, which impairs circulation and delays wound healing. Chronic hyperglycemia can lead to reduced immune response and increased susceptibility to infections and pressure ulcers.
