Furosemide Flashcards
What is the classification of Furosemide?
Loop Diuretic
Furosemide is primarily classified as a loop diuretic, which is used to treat conditions involving fluid retention.
What is the oral dosage range for Furosemide?
20-80 mg daily or divided
The dosage varies depending on the patient’s needs and response.
What is the IV dosage for Furosemide?
20-40 mg, may repeat in 1-2 hours
IV administration may be used for more rapid effects, especially in acute settings.
What is the mechanism of action of Furosemide?
Inhibits sodium and chloride reabsorption in the ascending loop of Henle
This action leads to increased urine production and diuresis.
What are the primary indications for Furosemide?
- Edema associated with heart failure
- Kidney/liver disease
- Pulmonary edema
- Hypertension
- Resolves peripheral edema
Furosemide is often used to manage fluid overload in various medical conditions.
What are common adverse effects of Furosemide?
- Hypokalemia
- Dehydration
- Hypotension
- Hyponatremia
- Ototoxicity (s/s tinnitus)
- Hyperglycemia
Patients should be monitored for these potential side effects during treatment.
What should be monitored when a patient is on Furosemide?
- Electrolytes (sodium and potassium)
- Intake and output (I&O)
- Blood pressure
- Daily weights
- Skin turgor
Monitoring these parameters helps ensure safe and effective use of the medication.
What is the normal range for sodium and potassium electrolytes?
- Sodium: 135-145
- Potassium: 3.5-5
Maintaining these electrolyte levels is crucial to prevent complications associated with Furosemide.
When should Furosemide be administered to a patient?
In the morning with food
This schedule helps prevent gastrointestinal upset and maximizes the effectiveness of the diuretic.
What dietary advice should be given to patients taking Furosemide?
Consume foods high in potassium
This helps counteract the risk of hypokalemia associated with Furosemide use.
True or False: Furosemide can cause hyperglycemia in diabetic patients.
True
Diabetic patients should closely monitor their glucose levels while on Furosemide.
What interactions should be considered when administering Furosemide?
- Increased risk of hypokalemia with digoxin
- Risk of hypotension with antihypertensives
Awareness of these interactions is important for patient safety.
What should be done if a patient is allergic to sulfa?
Do not administer Furosemide
Sulfa allergies can lead to serious adverse reactions with sulfa-containing medications like Furosemide.
