The nurse is teaching a 62-year-old client about hydrochlorothiazide, which the health care provider has prescribed for treatment of hypertension. What statement, made by the client, suggests that the client understands the teaching?
"I will need to stand slowly."
A client is receiving triamterene. The nurse instructs the client to avoid what foods? (Select all that apply.)

2 hours
The health care provider orders furosemide for a pediatric client. The nurse knows that the established dose of the drug should not exceed how many milligrams per kilogram of body weight per day?

A client with a long-standing diagnosis of heart failure has been taking hydrochlorothiazide (HCTZ) for several weeks. The client reports experiencing moderate diuresis, but the care provider and the client agree that increased diuresis would be of benefit. However, the care provider has explained that the client is likely near the ceiling threshold of this drug. What is the main implication when a client prescribed hydrochlorothiazide (HCTZ) is told they are, "nearing the drug's ceiling threshold"?
A higher dose of HCTZ will not result in increased diuresis.
A nurse is reviewing the medical record of a client with seizures and notes that the client is taking a drug classified as a diuretic. Which medication would the nurse identify?
Acetazolamide
What sign is most indicative of dehydration in a patient taking diuretics?
Body weight
A patient is prescribed a thiazide diuretic that is to be administered intravenously. Which agent would this most likely be? - Hydrochlorothiazide - Bendroflumethazide - Chlorothiazide - Methylchlothiazide
Chlorothiazide Rationale: All of these thiazide diuretics are orally administered, but only chlorothiazide is also administered intravenously.
The nurse is evaluating an 82-year-old client's medical record. The client is receiving hydrochlorothiazide. What abnormal laboratory result is related to the medication?
Elevated uric acid levels
A nurse is caring for a patient with edema due to congestive heart failure (CHF). The physician has prescribed indapamide to the patient. The patient is also undergoing treatment with digitalis glycoside. Which intervention should the nurse perform when caring for this patient?

Diuretics can either block the reabsorption of components of the urine or block the reabsorption of water back into the body. What does the increase in urine flow from the body depend on with a patient on loop diuretics?
The amount of sodium and chloride reabsorption that it blocks Rationale: The increase in urine flow that a diuretic produces is related to the amount of sodium and chloride reabsorption that it blocks.
