Study Notes
Diuretics
- Diuretics are medications that increase urine output.
- Several types of diuretics exist for different purposes
Types of Diuretics
- Thiazide and thiazide-like (e.g., hydrochlorothiazide)
- Loop or high-ceiling (e.g., furosemide)
- Osmotic (e.g., mannitol)
- Potassium-sparing (e.g., spironolactone)
Thiazide Diuretics - Hydrochlorothiazide
- Action: Works in the kidneys, promotes excretion of sodium, potassium, and water. Acts on the distal convoluted renal tubule.
- Uses: Treating hypertension, edema from heart failure
- Side Effects/Adverse Reactions: Dizziness, headache, weakness, GI distress, photosensitivity, fluid and electrolyte imbalances, hypotension (including orthostatic hypotension), hyperglycemia, hypokalemia, and dysrhythmias.
- Contraindications: Renal failure, electrolyte depletion, hepatic dysfunction, diabetes mellitus
- Interactions: Increased digoxin toxicity with hypokalemia, Anti-diabetic drugs, Steroids
Loop Diuretics - Furosemide
- Action: Inhibits water and sodium reabsorption; potassium, magnesium, and calcium are also excreted. Acts on the ascending loop of Henle.
- Uses: Treating fluid retention (caused by heart failure, renal dysfunction, cirrhosis, hypertension, pulmonary edema)
- Side Effects/Adverse Reactions: GI distress, dizziness, weakness, photosensitivity, fluid and electrolyte imbalances, orthostatic hypotension, hypotension, hyperglycemia, hearing loss (especially with rapid IV administration).
- Contraindications: Severe electrolyte imbalance, hypovolemia, allergy to sulfa drugs, caution with heart failure and diabetes
- Interactions: Anticoagulants (increased bleeding risk), Steroids (increased potassium loss), Digoxin (if hypokalemia is present).
K-Wasting Diuretics Lab Abnormalities
- Hypokalemia
- Hypomagnesemia
- Hypochloremia
- Hyponatremia
- Hyperglycemia
- Hypocalcemia in loop diuretics
- Hypercalcemia in thiazide diuretics
Osmotic Diuretics - Mannitol
- Action: Causes water, sodium, chloride, potassium to be excreted through the kidneys.
- Use: Decrease intracranial pressure (e.g., cerebral edema), decrease intraocular pressure, promote excretion of toxic substances. Usually used in emergency situations
- Side Effects/Adverse Reactions: GI upset, fluid and electrolyte imbalance, pulmonary edema, tachycardia, rapid fluid loss/acidosis, extreme caution, heart disease, heart failure, renal failure
Potassium-Sparing Diuretics - Spironolactone
- Action: Blocks the action of aldosterone, thereby promoting sodium and water excretion, and potassium retention; also excretes magnesium and calcium. Can increase blood glucose.
- Uses: Treating heart failure, hepatic cirrhosis
- Side Effects/Adverse Reactions: GI distress, dizziness, weakness, erectile dysfunction, orthostatic hypotension, hypotension, fluid and electrolyte imbalance, hyperkalemia
- Contraindications: Severe kidney/renal disease, hyperkalemia
- Interactions: Potassium supplements, ACE inhibitors and angiotensin II receptor blockers, salt substitutes containing potassium
Nursing Process: Diuretics
-
Assessment: Medication/medical history, vital signs, fluid and electrolyte levels/weight, renal/hepatic function, allergies
-
Interventions: Monitor I&O, daily weight, notify healthcare provider if urine output doesn't increase, monitor vitals (especially blood pressure), administer IV furosemide slowly, watch for signs of hypokalemia/hyperkalemia, monitor electrolyte levels, monitor glucose periodically
-
Teaching: Take before dose, weigh daily, take with food (if GI upset), avoid sun (if photosensitivity), get up slowly, reinforce need for medication, potassium-wasting diets should increase potassium, potassium supplements may be necessary, potassium-sparing diets should decrease potassium; inform patient that some drugs may increase glucose
Practice Questions (with answers and rationale)
- (Note: The practice questions and rationales from the provided slides are included below.)*
- Question 1:* A client taking furosemide... Answer: C (low serum potassium, sodium, magnesium, and calcium) Rationale: Loop diuretics cause potassium loss
- Question 2:* Which statement about loop diuretics... Answer: C (Rise slowly to prevent dizziness) Rationale: The medication is taken in the morning, not at bedtime and with food.
- Question 3:* A client with increased intracranial pressure... Answer: B (mannitol (Osmitrol))
- Question 4:* A client receiving furosemide... Answer: B (hypokalemia) Rationale: Furosemide is a potassium-wasting diuretic.
- Question 5:* A client with congestive heart failure... Answer: C (2L) Rationale: Weight gain of 2.2 pounds is equivalent to excess 1 liter of fluid.
- Question 6:* Before administering spironolactone... Answer: B (digoxin (Lanoxin)) Rationale: Spironolactone is a potassium-sparing diuretic. Potassium supplementation is not indicated unless the client's potassium is low.
- Question 7:* Which statement about aldosterone... Answer: B (is a mineralocorticoid hormone) Rationale: Promotes sodium retention and potassium excretion
