C. Thiazide diuretics like hydrochlorothiazide can cause orthostatic hypotension, which may contribute to the client's symptoms of dizziness and light-headedness upon standing. Advising the client to change positions slowly can help mitigate these symptoms by allowing the body time to adjust to changes in posture and blood pressure. D. Thiazide diuretics can alter electrolyte levels, including potassium, which is critical for normal cardiac function. Although the client's potassium level (3.4 mEq/L) is within the normal range, ongoing monitoring for potential dysrhythmias is prudent due to the electrolyte-altering effects of hydrochlorothiazide. E. Given the client's report of dizziness and light-headedness upon standing, checking for orthostatic hypotension is important. Thiazide diuretics can cause volume depletion and subsequent orthostatic hypotension, especially in older adults. Assessing blood pressure and symptoms in supine and standing positions will help evaluate for orthostatic changes. A. This is not typically recommended for hydrochlorothiazide. It is usually advised to take this medication in the morning to avoid nighttime diuresis and nocturia. Therefore, this action is not appropriate. B. Hydrochlorothiazide is a thiazide diuretic that can cause potassium loss through increased urine output. Restricting potassium intake is not typically necessary unless potassium levels drop significantly below the normal range. Given that the client's potassium level is within the normal range (3.4 mEq/L), advising strict potassium restriction is not indicated at this time.
