The nurse initiates an infusion of piperacillin-tazobactam for a client with a urinary tract infection. Five minutes into the infusion, the client reports not feeling well. Which client manifestation should the nurse identify as a reason to stop the infusion?

Choice A rationale: Administering the dose of labetalol without further assessment may not be appropriate in this situation. The client's heart rate is 48 beats/minute, which is considered bradycardia (heart rate below the normal range of 60-100 beats/minute). Bradycardia can be a potential adverse effect of labetalol, a beta-blocker. Moreover, the client's blood pressure is elevated at 150/90 mm Hg, indicating that the hypertension is not well controlled. Administering the dose without addressing the bradycardia or elevated blood pressure could potentially exacerbate these issues.

Choice B rationale: Withholding the scheduled dose of labetalol is the most appropriate action in this scenario. The client's heart rate of 48 beats/minute is considered bradycardia, which may be a side effect of labetalol or indicative of an underlying issue. Additionally, the client's blood

pressure is elevated, indicating inadequate control of hypertension. Bradycardia can reduce cardiac output and may lead to further complications. Notifying the healthcare provider is essential to obtain further instructions and address the client's bradycardia and hypertension before administering the medication.

Choice C rationale: While telemetry monitoring is appropriate for clients with certain cardiac conditions or when changes in heart rate need close observation, it may not be the most urgent action in this situation. The client's bradycardia and elevated blood pressure are concerning and require immediate attention. Telemetry monitoring may be considered later, but it does not address the immediate need to withhold the medication and seek guidance from the healthcare provider.

Choice D rationale: Orthostatic hypotension refers to a drop in blood pressure when changing positions, such as from lying down to standing up. While orthostatic hypotension is a valid concern for clients taking antihypertensive medications, it is not the primary issue in this scenario. The client's heart rate is 48 beats/minute, indicating bradycardia and the blood pressure is elevated at 150/90 mm Hg, suggesting uncontrolled hypertension. These are the main concerns that require immediate attention and further assessment before administering the labetalol dose.

Choice A rationale: this is not an appropriate response because while it may reduce the intake of vitamin K, suddenly changing the client's diet drastically may not be necessary. It is essential for the healthcare provider to make any necessary adjustments to the medication based on the client's diet.

Choice B rationale: Warfarin is an anticoagulant medication that works by inhibiting the formation of blood clots. It interacts with vitamin K, which plays a crucial role in the blood clotting process. Leafy green vegetables are rich in vitamin K, and their consumption can affect the effectiveness of warfarin. The nurse should advise the client to inform her healthcare provider about her vegetarian diet and the regular consumption of leafy green vegetables. The healthcare provider will then be able to adjust the warfarin dosage accordingly to ensure that the client receives the appropriate and consistent level of anticoagulation.

Choice C rationale: while a vegetarian diet can be healthy, the specific concern here is the potential impact of vitamin K-rich foods on warfarin therapy. It's essential to address this potential interaction rather than focusing solely on the overall healthy lifestyle.

Choice D rationale: Consuming large amounts of leafy green vegetables and vitamin K-rich foods may actually reduce the effectiveness of warfarin, leading to a decreased ability to prevent blood clots. Therefore, it is crucial to consult with the healthcare provider to manage the dosage appropriately.
