A nurse is caring for a client who has impaired mobility. Which of the following support devices should the nurse plan to use to prevent the client from developing plantar flexion contractures?

A. Potassium level is incorrect because it is within the normal range and does not affect wound healing directly.
B. Prealbumin level is correct because it is low, indicating malnutrition and poor protein intake, which are essential for tissue repair and immune function.
C. History of diabetes mellitus is correct because it causes impaired blood flow, increased risk of infection, and delayed inflammatory response, which all hinder wound healing.
D. History of hyperlipidemia is correct because it causes atherosclerosis and reduced blood supply to the affected area, which limits oxygen and nutrient delivery to the wound.
E. Wound infection is correct because it increases inflammation, tissue damage, and metabolic demands, which prolong the healing process and may lead to complications.
F. Decreased pedal perfusion is correct because it indicates poor circulation to the lower extremities, which impairs wound healing by reducing oxygen and nutrient delivery to
the wound.
G. Fasting blood glucose is incorrect because it is not a direct cause of delayed wound healing, but rather a reflection of the client's diabetes management. However, high blood glucose levels can impair wound healing by affecting blood flow, immune function, and collagen synthesis.

a. Hypertension and crackles:

While hypertension can be associated with various conditions, such as cardiovascular diseases or stress, it is not directly related to the cessation of TPN infusion.

Crackles in the lungs are often indicative of fluid accumulation or inflammation, commonly seen in conditions like pneumonia or heart failure. They are not typically associated with the interruption of TPN infusion.

b. Fever and chills:

Fever and chills can be symptoms of infection or inflammatory processes in the body. However, they are not specifically related to the interruption of TPN infusion.

In the context of TPN cessation, the focus would be on metabolic changes rather than infectious processes.

c. Excessive thirst and urination:

Excessive thirst and urination are classic symptoms of hyperglycemia, which can occur when TPN, particularly if it contains a high glucose concentration, is abruptly interrupted.

When TPN infusion stops, there is no longer a continuous supply of glucose to the body, leading to increased blood glucose levels and subsequent polyuria (excessive urination) and polydipsia (excessive thirst) as the body tries to eliminate excess glucose.

d. Shakiness and diaphoresis:

Shakiness and diaphoresis (excessive sweating) are classic symptoms of hypoglycemia, which can occur if TPN, particularly if it contains a high concentration of insulin, is abruptly interrupted.

TPN solutions often contain glucose and insulin to maintain proper blood glucose levels. If the infusion is stopped suddenly, there may be a rapid decline in blood glucose levels, leading to hypoglycemia, which manifests as shakiness, diaphoresis, confusion, and other neuroglycopenic symptoms.
