A nurse is collecting data on a client who has acute pancreatitis. Which of the following factors should the nurse anticipate in the client’s history?

Choice A reason: Insulin injected into the thigh is not the most rapidly absorbed. The abdomen is the preferred site for insulin injection, as it has the fastest and most consistent absorption rate. The thigh, arm, and butock have slower and more variable absorption rates12.

Choice B reason: The botle of insulin should not be shaken before withdrawing the medication. Shaking can damage the insulin molecules and affect their potency and effectiveness. Instead, the botle should be gently rolled between the palms to mix the insulin evenly13.

Choice C reason: Lantus insulin should not be used immediately before each meal. Lantus is a long-acting insulin that provides a steady basal level of insulin for 24 hours. It should be taken once a day at the same time every day, regardless of meals. Humalog is a rapid-acting insulin that can be used immediately before each meal to cover the postprandial glucose spikes14.

Choice D reason: Unopened vials of insulin should be kept in the refrigerator until needed. This can help preserve their quality and potency until their expiration date. Opened vials of insulin can be kept at room temperature for up to 28 days, depending on the type and brand

Choice A: Weigh the client weekly. This is incorrect because the client receiving PN should be weighed daily, not weekly, to monitor fluid balance and nutritional status. The nurse should also measure the client’s intake and output, blood glucose, electrolytes, and other laboratory values daily.

Choice B: Reduce the rate of the solution gradually to discontinue. This is correct because the nurse should taper off the PN solution slowly to prevent rebound hypoglycemia, which can occur when the high concentration of glucose in the PN solution is abruptly stopped. The nurse should follow the provider’s orders or the facility’s protocol for reducing and discontinuing PN.

Choice C: Remove solution from refrigerator 2 hr before infusion. This is incorrect because the nurse should remove the PN solution from the refrigerator 30 to 60 minutes before infusion, not 2 hr, to allow it to reach room temperature. Infusing a cold solution can cause discomfort, vasoconstriction, and impaired absorption of nutrients.

Choice D: Shake the solution before hanging if there is a layer of fat present on the top. This is incorrect because the nurse should not shake the PN solution at all, as this can cause fat emulsion droplets to coalesce and form large particles that can clog the filter or cause embolism. The nurse should gently invert or roll the PN solution container to mix it if there is any separation of components.
