A client with atrial fibrillation receives a new prescription for dabigatran. Which instruction should the nurse include in this client's teaching plan?

Choice A reason: This is the correct manifestation for the nurse to identify as a reason to stop the infusion. A scratchy throat may indicate an allergic reaction to piperacillin-tazobactam, which is a penicillin derivative. The client may also develop other signs of anaphylaxis, such as rash, itching, swelling, wheezing, or difficulty breathing. The nurse should stop the infusion immediately and notify the healthcare provider.

Choice B reason: This is not a correct manifestation for the nurse to identify as a reason to stop the infusion. Pupillary constriction is not a common or serious side effect of piperacillin-tazobactam. It may be caused by other factors, such as light exposure, medication use, or neurological conditions. The nurse should monitor the client's pupils for any changes, but it is not a reason to stop the infusion.

Choice C reason: This is not a correct manifestation for the nurse to identify as a reason to stop the infusion. Bradycardia, or a slow heart rate, is not a common or serious side effect of piperacillin-tazobactam. It may be caused by other factors, such as cardiac disorders, medication use, or vagal stimulation. The nurse should monitor the client's vital signs for any changes, but it is not a reason to stop the infusion.

Choice D reason: This is not a correct manifestation for the nurse to identify as a reason to stop the infusion. Hypertension, or high blood pressure, is not a common or serious side effect of piperacillin-tazobactam. It may be caused by other factors, such as stress, pain, or renal disorders. The nurse should monitor the client's blood pressure for any changes, but it is not a reason to stop the infusion.

Choice A reason: This is not the most important adverse effect for the nurse to report. Nausea is a common side effect of metoclopramide, which is a prokinetic and antiemetic drug that stimulates the motility of the upper GI tract and blocks the dopamine receptors in the chemoreceptor trigger zone. Nausea may be mild or moderate, and it may subside with time or dose adjustment. The nurse should monitor the client's nausea and provide supportive measures, such as fluids, crackers, or ginger, but it is not a priority.

Choice B reason: This is the most important adverse effect for the nurse to report. Involuntary movements, or extrapyramidal symptoms, are a serious and potentially irreversible side effect of metoclopramide, which can occur due to the blockade of the dopamine receptors in the basal ganglia. Involuntary movements can include dystonia, akathisia, parkinsonism, or tardive dyskinesia, and they can affect the face, neck, limbs, or trunk. The nurse should assess the client for any signs of involuntary movements and notify the healthcare provider immediately. The nurse should also prepare to administer an anticholinergic drug, such as benztropine, to counteract the effects of metoclopramide.

Choice C reason: This is not the most important adverse effect for the nurse to report. Unusual irritability is a rare and mild side effect of metoclopramide, which may be related to the central nervous system effects of the drug. Unusual irritability may manifest as restlessness, anxiety, or agitation, and it may resolve with time or dose adjustment. The nurse should monitor the client's mood and behavior and provide reassurance and comfort, but it is not a priority.

Choice D reason: This is not the most important adverse effect for the nurse to report. Diarrhea is a rare and mild side effect of metoclopramide, which may be related to the increased motility of the GI tract. Diarrhea may be transient or self-limiting, and it may be managed with fluids, electrolytes, or antidiarrheal drugs. The nurse should monitor the client's stool frequency and consistency and provide hydration and hygiene, but it is not a priority.
