Which of the following statements by the client indicates understanding of Tylenol patient teaching?

A. Drinking grape juice to acidify urine is not necessary for Tylenol (acetaminophen) therapy and does not enhance its effectiveness; this is unrelated patient teaching. B. Performing perineal care back-to-front increases the risk of introducing bacteria from the rectal area to the urinary tract and is incorrect. Proper technique is front-to-back. C. Drinking large amounts of fluids helps flush bacteria from the urinary tract, which is an important supportive measure when managing urinary discomfort or infection. This demonstrates correct understanding of general patient teaching related to urinary health. D. Taking Tylenol for any discomfort without considering dosage limits or underlying conditions could be unsafe; patient teaching should include using the correct dose and monitoring total daily intake to avoid liver toxicity.
