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: Hematemesis is the vomiting of blood, which can indicate a serious gastrointestinal bleeding caused by ibuprofen. This is a life-threatening condition that requires immediate medical attention. Therefore, the nurse should report this finding to the healthcare provider as soon as possible.

Choice B reason: Insomnia is the difficulty in falling asleep or staying asleep. It can be a side effect of ibuprofen, but it is not as serious or urgent as hematemesis. The nurse can advise the client to take ibuprofen with food or milk, avoid caffeine and alcohol, and practice good sleep hygiene.

Choice C reason: Dizziness is the feeling of lightheadedness, faintness, or unsteadiness. It can also be a side effect of ibuprofen, but it is usually mild and transient. The nurse can instruct the client to rise slowly from a sitting or lying position, drink plenty of fluids, and avoid driving or operating machinery if dizzy.

Choice D reason: Nausea is the feeling of discomfort or unease in the stomach that may lead to vomiting. It can also be a side effect of ibuprofen, but it is usually manageable with simple measures. The nurse can suggest the client to take ibuprofen with food or milk, eat small and frequent meals, and avoid spicy or fatty foods.

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.
