A female client with multiple sclerosis reports having less fatigue and improved memory since she began using the herbal supplement, ginkgo biloba. Which information is most important for the nurse to include in the teaching plan for this client?

Choice A reason: Hypertension is not a typical sign of an allergic reaction to piperacillin-tazobactam, which is an antibiotic. It may be caused by other factors, such as pain, anxiety, or renal impairment. The nurse should monitor the client's blood pressure and report any abnormal findings.

Choice B reason: Bradycardia is not a common or serious side effect of piperacillin-tazobactam. It may be related to other medications, such as beta-blockers, or underlying cardiac conditions. The nurse should check the client's pulse and rhythm and report any changes.

Choice C reason: Pupillary constriction is not associated with piperacillin-tazobactam or an allergic reaction. It may be caused by other drugs, such as opioids, or neurological disorders. The nurse should assess the client's level of consciousness and pupillary response.

Choice D reason: Scratchy throat is a possible sign of anaphylaxis, which is a severe and potentially fatal allergic reaction to piperacillin-tazobactam or any other drug. Other symptoms may include hives, swelling, wheezing, or hypotension. The nurse should stop the infusion immediately and call for help.

Choice A reason: Recent use of other antidepressants is important to know, as duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI) that can interact with other antidepressants, especially monoamine oxidase inhibitors (MAOIs) and selective serotonin reuptake inhibitors (SSRIs). However, this information is not as important as liver function laboratory results, as duloxetine can cause hepatotoxicity in some clients.

Choice B reason: Weight change in the last month is relevant to monitor, as duloxetine can cause weight loss or gain in some clients. However, this information is not as important as liver function laboratory results, as duloxetine can cause liver damage in some clients.

Choice C reason: Family history of mental illness is useful to assess, as duloxetine may be more effective or less effective in clients with certain genetic factors. However, this information is not as important as liver function laboratory results, as duloxetine can cause liver failure in some clients.

Choice D reason: Liver function laboratory results are most important to obtain, as duloxetine is metabolized by the liver and can cause hepatotoxicity in some clients. The nurse should monitor the client's liver enzymes and bilirubin levels before and during treatment with duloxetine and report any signs of liver impairment, such as jaundice, dark urine, abdominal pain, or fatigue.
