When caring for a patient after lumbar spinal surgery, the nurse would immediately report which finding to the healthcare provider?
The patient has loss of sensation to the perineum, buttocks, inner thighs, and back of the legs.
The patient is nauseated and has not voided in 4 hours.
The patient reports mild low back pain.
The patient has a single episode of emesis.
The Correct Answer is A
Choice A rationale
Loss of sensation to the perineum, buttocks, inner thighs, and back of the legs may indicate cauda equina syndrome, a surgical emergency. This condition involves compression of the spinal nerve roots and can lead to permanent neurological damage if not promptly addressed. Immediate medical intervention is critical.
Choice B rationale
Nausea and delayed voiding postoperatively are common, potentially due to anesthesia effects or limited mobility. While these findings warrant monitoring, they do not typically indicate an urgent issue unless prolonged or associated with other complications.
Choice C rationale
Mild low back pain is expected after lumbar spinal surgery due to manipulation of spinal structures. Pain management with prescribed analgesics and gradual mobilization is part of the standard postoperative care plan, and it does not usually necessitate immediate reporting.
Choice D rationale
A single episode of emesis can result from anesthesia effects or medication. Unless accompanied by persistent vomiting, signs of aspiration, or electrolyte imbalances, isolated emesis is not typically urgent and should be managed with antiemetics if necessary.

Correct Answer is C
Explanation
Choice A rationale
Glyburide does not stimulate glucose uptake directly in skeletal muscles. Instead, it acts on pancreatic beta cells, affecting insulin release. Enhancing muscular glucose uptake occurs through insulin’s action downstream.
Choice B rationale
Glyburide does not primarily increase insulin sensitivity. Agents like metformin work to sensitize cells to insulin, but Glyburide functions by stimulating endogenous insulin release.
Choice C rationale
Glyburide stimulates insulin release from pancreatic beta cells by closing ATP-sensitive potassium channels, leading to calcium influx and insulin secretion. This increases circulating insulin, aiding glucose uptake and reducing blood glucose levels.
Choice D rationale
Glyburide does not inhibit carbohydrate breakdown in the intestines. Medications like alpha-glucosidase inhibitors target intestinal enzymes to slow carbohydrate digestion, unlike Glyburide’s pancreatic action.
Correct Answer is B
Explanation
Choice A rationale
Mixing insulin glargine and lispro in the same syringe is contraindicated due to their incompatible chemical formulations. Glargine’s acidic pH alters lispro’s effectiveness when mixed, impairing glycemic control. Separate administration preserves their individual pharmacokinetics and therapeutic actions.
Choice B rationale
Separate injections ensure each insulin maintains its unique action profile. Glargine provides basal control, while lispro manages rapid postprandial spikes. Their chemical incompatibility mandates separate administration, optimizing glycemic management and reducing potential adverse effects from mixed formulations.
