A client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?

A) Monitoring blood pressure: Tamsulosin is an alpha-adrenergic blocker used to relax the muscles in the prostate and bladder neck, improving urinary flow in benign prostatic hyperplasia (BPH). Monitoring blood pressure is important because tamsulosin can cause orthostatic hypotension, especially when starting the medication or increasing the dose.
B) Assessing urine output: This is the correct answer. Tamsulosin can cause urinary retention, especially in patients with bladder outlet obstruction. Monitoring urine output helps assess for any signs of urinary retention or decreased urinary flow.
C) Obtaining daily weights: This is not typically necessary for monitoring the effects of tamsulosin. Changes in weight may occur due to other factors and are not directly related to the medication.
D) Performing a bladder scan: While performing a bladder scan may be indicated if there are specific concerns about urinary retention, assessing urine output is a more direct and immediate way to monitor for this adverse reaction.

A) Expresses that they cannot get enough air to breathe: While this statement suggests respiratory distress, it is not as objective an assessment finding as a respiratory rate of 7 breaths/minute. Objective measurements are typically more reliable indicators for initiating interventions.
B) Respiratory rate of 7 breaths/minute: A respiratory rate of 7 breaths/minute is indicative of respiratory depression, which is a potential side effect of opioid analgesics like morphine sulfate. Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression. Administering a prescribed PRN dose of naloxone is appropriate to counteract the respiratory depression and prevent further complications.
C) Bilateral wheezing on auscultation: Wheezing is more commonly associated with bronchoconstriction or airway obstruction rather than opioid-induced respiratory depression. Naloxone is not indicated for wheezing unless there is concurrent opioid-induced respiratory depression.
D) Pulse oximeter reading of 89% on room air: While a pulse oximeter reading of 89% indicates hypoxemia, it may not be solely due to opioid-induced respiratory depression. Other factors, such as hypoventilation, ventilation-perfusion (V/Q) mismatch, or lung disease, could contribute to decreased oxygen saturation. Administering naloxone solely based on pulse oximetry readings may not address the underlying cause adequately. It is essential to assess the client comprehensively, considering clinical signs and symptoms along with objective data.
