Which instruction about insulin administration should nurse Kate give to a client?

  

    A. “Always follow the same order when drawing the different insulins into the syringe.”

    B. “Shake the vials before withdrawing the insulin.”

    C. “Store unopened vials of insulin in the freezer at temperatures well below freezing.”

    D. “Discard the intermediate-acting insulin if it appears cloudy.”

    

    

Correct Answer: A. “Always follow the same order when drawing the different insulins into the syringe.”

The client should be instructed always to follow the same order when drawing the different insulins into the syringe. Insulin is considered the most potent anabolic hormone known until today, and its effects on the body are necessary for tissue development, growth, and maintenance of glucose homeostasis. Insulin action starts by binding to two cell receptors, which are alpha and beta, that are linked by two disulfide bonds into a complex that is a heterotetrameric membrane.

Option B: Insulin should never be shaken because the resulting froth prevents withdrawal of an accurate dose and may damage the insulin protein molecules. For intravenous infusions, to minimize insulin adsorption to plastic IV tubing, flush the intravenous tube with priming infusion of 20 mL from a 100 mL-polyvinyl chloride bag insulin, every time a new intravenous tubing is added to the insulin infusion container.

Option C: Insulin also should never be frozen because the insulin protein molecules may be damaged. Insulin, regular when administered subcutaneously, it should be injected 30 to 40 minutes before each meal. Avoid cold injections. The injection is in the buttocks, thighs, arms, or abdomen; it is necessary to rotate injection sites to avoid lipodystrophy.

Option D: Intermediate-acting insulin is normally cloudy. In regular insulin, do not inject if the solution is viscous or cloudy; use only if clear and colorless. When administered intravenously, U-100 administration should be with close monitoring of serum potassium and blood glucose. Do not use if the solution is viscous or cloudy; administration should only take place if it is colorless and clear.
