A client with overactive bladder starts a new prescription for oxybutynin. When assessing the client prior to medication administration, which finding should the practical nurse (PN) report to the charge nurse?

Choice A reason: Gum appearance is unrelated to carbamazepine’s side effects or sore throat. While some antiseizure drugs cause gingival hyperplasia, carbamazepine does not, and gum assessment does not clarify the sore throat’s cause, which may indicate infection or agranulocytosis, making this choice irrelevant.

Choice B reason: Bowel sounds assess gastrointestinal function, not relevant to a sore throat or carbamazepine’s effects. Sore throat may signal agranulocytosis, a rare side effect, but bowel sounds do not provide data on infection or hematologic issues, making this choice inappropriate.

Choice C reason: Carotid pulse volume evaluates cardiovascular status but is unrelated to sore throat or carbamazepine’s side effects. Sore throat may indicate infection or agranulocytosis, requiring systemic assessment like temperature, not vascular checks, making this choice irrelevant for the reported symptom.

Choice D reason: Temperature is critical, as sore throat may indicate infection or agranulocytosis, a rare but serious carbamazepine side effect causing low white blood cells. Fever suggests infection, necessitating urgent reporting. This assessment provides key data to differentiate causes, guiding timely intervention.

Choice A reason: A neurological exam assesses brain function but does not directly address glipizide-related symptoms like confusion and blurred vision, which suggest hypoglycemia. Glipizide, a sulfonylurea, lowers blood glucose, and these symptoms are likely due to low glucose levels, making glucose testing more urgent than a neurological evaluation.

Choice B reason: Administering glucagon treats severe hypoglycemia but is premature without confirming low blood glucose. Glipizide increases insulin release, potentially causing hypoglycemia, but a fingerstick glucose test is needed first to verify the cause of symptoms. This choice is incorrect without diagnostic confirmation.

Choice C reason: Measuring vital signs provides general health data but does not specifically address confusion and blurred vision caused by glipizide-induced hypoglycemia. Low blood glucose is the likely cause, and testing glucose levels is more direct and urgent than monitoring vital signs, which are secondary in this context.

Choice D reason: Obtaining a fingerstick blood glucose is critical, as glipizide can cause hypoglycemia, leading to confusion and blurred vision. These symptoms result from insufficient glucose in the brain and eyes. Confirming low glucose guides immediate treatment, such as glucose administration, making this the most appropriate action.
