A patient with diabetes is starting on insulin therapy. Which type of insulin will the nurse discuss using for mealtime coverage?

Choice A reason: This statement is false. 3% Sodium Chloride is a hypertonic solution that can cause fluid overload, hypernatremia, and cellular dehydration. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses.

Choice B reason: This statement is false. Dextrose 10% in water is a hypotonic solution that can cause fluid shifts, hyponatremia, and cellular edema. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses.

Choice C reason: This statement is true. 0.9% Sodium Chloride with 40 mEq Potassium (KCl) is an isotonic solution that can maintain fluid and electrolyte balance. It is indicated for a patient with nausea, vomiting, and Salmonella infection, who is likely to have fluid and electrolyte losses, especially sodium and potassium.

Choice D reason: This statement is false. Lactated Ringers is an isotonic solution that can maintain fluid and electrolyte balance, but it also contains lactate, which can be converted to bicarbonate in the liver. It is not indicated for a patient with nausea, vomiting, and Salmonella infection, who may have metabolic acidosis due to diarrhea and lactate accumulation.

Choice A reason: Lispro (Humalog) is a type of insulin that is used for mealtime coverage. It is a rapid-acting insulin that starts to work within 15 minutes, peaks in about an hour, and lasts for 2 to 4 hours. It mimics the natural insulin response to food intake, and helps to lower the blood glucose level after meals. The nurse will discuss using lispro for mealtime coverage, and instruct the patient to inject it within 15 minutes before or after eating.

Choice B reason: NPH (Humulin N) is a type of insulin that is not used for mealtime coverage. It is an intermediate-acting insulin that starts to work within 2 to 4 hours, peaks in 4 to 12 hours, and lasts for 12 to 18 hours. It provides a steady background of insulin throughout the day, and helps to control the blood glucose level between meals and overnight. The nurse will discuss using NPH for basal coverage, and instruct the patient to inject it once or twice a day, usually in the morning and/or evening.

Choice C reason: Detemir (Levemir) is a type of insulin that is not used for mealtime coverage. It is a long-acting insulin that starts to work within 1 to 2 hours, has no peak, and lasts for up to 24 hours. It provides a constant level of insulin throughout the day, and helps to maintain the blood glucose level at a stable range. The nurse will discuss using detemir for basal coverage, and instruct the patient to inject it once or twice a day, depending on the individual needs.

Choice D reason: Glargine (Lantus) is a type of insulin that is not used for mealtime coverage. It is a long-acting insulin that starts to work within 1 to 2 hours, has no peak, and lasts for up to 24 hours. It provides a constant level of insulin throughout the day, and helps to maintain the blood glucose level at a stable range. The nurse will discuss using glargine for basal coverage, and instruct the patient to inject it once a day, usually at the same time every day.
