A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?

Choice A reason: Neutropenic precautions are necessary when the WBC count is critically low, typically below the normal range. Since the client’s WBC count is now within the normal range, these precautions are no longer required.

Choice B reason: Filgrastim is designed to increase white blood cell (WBC) production in individuals with neutropenia. In this case, the client’s WBC count has increased from 2,500/mm³ (2.5 x 10⁹/L) to 5,000/mm³ (5 x 10⁹/L), reaching the lower limit of the normal reference range (5,000 to 10,000/mm³ or 5 to 10 x 10⁹/L). This indicates that the medication has achieved its desired effect, and it is appropriate to inform the client of this positive outcome.

Choice C reason:reason: Reviewing culture and sensitivity reports would be relevant if there was evidence of infection or a need to evaluate ongoing treatment for an infection. This is not indicated by the scenario provided.

Choice D reason: While assessing vital signs is generally important, there is no indication in this scenario that an acute issue requiring immediate vital sign monitoring is present.

Choice A reason: Assessing for orthostatic hypotension before administering the dose is not necessary, as labetalol does not cause orthostatic hypotension. Orthostatic hypotension is a condition where the blood pressure drops significantly when changing positions from lying to sitting or standing. Labetalol is a beta-blocker that lowers blood pressure by reducing the heart rate and cardiac output.

Choice B reason: Administering the dose and monitoring the client's B/P regularly is not appropriate, as labetalol may cause further bradycardia (slow heart rate) in this client. The client's heart rate is already below normal (48 beats/minute), which may indicate that labetalol is overdosed or contraindicated. Bradycardia can lead to decreased perfusion, dizziness, fatigue, and fainting.

Choice C reason: Applying a telemetry monitor before administering the dose is not sufficient, as labetalol may cause serious cardiac arrhythmias (irregular heart rhythms) in this client. The client's heart rate is already below normal (48 beats/minute), which may indicate that labetalol is affecting the electrical conduction system of the heart. Arrhythmias can cause palpitations, chest pain, shortness of breath, and cardiac arrest.

Choice D reason: Withholding the scheduled dose and notifying the healthcare provider is the best action for the nurse to take in this situation. The client's heart rate is already below normal (48 beats/minute), which may indicate that labetalol is causing adverse effects or interactions with other medications. The healthcare provider should be informed of the client's vital signs and medication history, and decide whether to adjust or discontinue labetalol.
