A postoperative patient who had surgery for a perforated gastric ulcer has been receiving nasogastric suction for 3 days. The patient now has a serum sodium level of 127 mEq/L (127 mmol/L). Which prescribed therapy should the nurse question?

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.

Choice A reason: This statement is false. Acetaminophen (Tylenol) is not the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as acetaminophen is a mild analgesic that works by inhibiting the synthesis of prostaglandins, which are involved in inflammation and pain. Acetaminophen is not very effective for chronic, burning leg pain, which is likely caused by diabetic neuropathy, a nerve damage condition that affects the sensation and function of the legs.

Choice B reason: This statement is true. Gabapentin (Neurontin) is the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as gabapentin is an anticonvulsant that works by modulating the activity of calcium channels, which are involved in transmitting pain signals from the nerves to the brain. Gabapentin is effective for chronic, burning leg pain, as it can reduce the intensity and frequency of neuropathic pain.

Choice C reason: This statement is false. Hydrocodone-Acetaminophen (Norco) is not the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as hydrocodone-acetaminophen is a combination of an opioid analgesic and a mild analgesic that works by binding to opioid receptors in the brain and spinal cord, and by inhibiting the synthesis of prostaglandins, respectively. Hydrocodone-acetaminophen is not very effective for chronic, burning leg pain, as it can cause tolerance, dependence, and addiction, and can also interact with oxycodone, which the patient is already taking.

Choice D reason: This statement is false. Aspirin is not the best choice for the nurse to administer as an adjuvant to decrease the patient's pain, as aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting the synthesis of prostaglandins, which are involved in inflammation and pain. Aspirin is not very effective for chronic, burning leg pain, as it can cause gastrointestinal bleeding, ulcers, and kidney damage, and can also interact with other medications that the patient may be taking, such as anticoagulants or antiplatelets.
