Chap 28 (exam 3) Flashcards
Potent diuretics that act along the ascending limb of the loop of Henle; furosemide is an example
Loop diuretics
Abbreviation for the term that describes a gauge of how well the kidneys are functioning as filters
GFR
A general term for drugs that accelerate the rate of urine formation
Diuretics
The main structural unit of the kidney
Nephron
Part of the kidney structure located between the proximal and distal convoluted tubules
Loop of Henle
Diuretics that result in the diuresis of sodium and water and the retention of potassium; spironolactone is an example
Potassium-sparing diuretics
Diuretics that act on the distal convoluted tubule, where they inhibit sodium and water resorption; hydrochlorothiazide (HCTZ) is an example
Thiazides
Abbreviation for a class of diuretics that inhibit the enzyme carbonic anhydrase; acetazolamide is an example
CAIs
Drugs that induce diuresis by increasing the osmotic pressure of the glomerular filtrate, which results in rapid diuresis; mannitol is an example
Osmotic diuretics
An abnormal intraperitoneal accumulation of fluid
Ascites
Which are indications for the use of diuretics? Select all that apply:
To increase urine output
To reduce uric acid levels
To treat hypertension
To treat open-angle glaucoma
To treat edema associated with heart failure
To increase urine output
To treat hypertension
To treat open-angle glaucoma
To treat edema associated with heart failure
When providing patient teaching to a patient who is taking a potassium-sparing diuretic such as spironolactone (Aldactone), the nurse will include which dietary guidelines?
There are no dietary restrictions with this medication
The patient needs to consume foods high in potassium, such as bananas and orange juice
The patient needs to avoid excessive intake of foods high in potassium
The patient needs to drink 1-2 L of fluid per day
The patient needs to avoid excessive intake of foods high in potassium
When teaching a patient about diuretic therpay, which would the nurse indicate as the best time of day to take these medications? Morning Midday Bedtime Time of day does not matter
Morning
When monitoring a patient for hypokalemia related to diuretic use, the nurse looks for which possible symptoms? Nausea, vomiting and anorexia Diarrhea and abdominal pain Orthostatic hypotension Muscle weakness and lethargy
Muscle weakness and lethargy
A patient with severe heart failure has been started on therapy with a carbonic anhydrase inhibitor (CAI), but the nurse mentions that this medication may be stopped in a few days. What is the reason for this short treatment?
CAIs are not the first choice for treatment of heart failure
Metabolic acidosis develops in 2-4 days after therapy is started
It is expected that CAIs will dramatically reduce the fluid overload related to heart failure
Allergic reactions to CAIs are common
Metabolic acidosis develops in 2-4 days after therapy is started
