Diuretics & Fluids
This class of highly potent diuretics, which includes furosemide, works by inhibiting the reabsorption of sodium and chloride in the thick ascending limb of the loop of Henle.
What are loop diuretics?
These lipoproteins are considered cardioprotective because they clear cholesterol from peripheral cells and transport it back to the liver.
What are High-Density Lipoproteins (HDLs)?
This class of medications lowers blood pressure by preventing the conversion of angiotensin I to angiotensin II, but can frequently trigger a persistent, dry nonproductive cough.
What are Angiotensin-Converting Enzyme (ACE) Inhibitors?
This is the fundamental functional difference between traditional anticoagulants and thrombolytic drugs?
What is that anticoagulants prevent clot formation/extension, while thrombolytics actively dissolve existing clots?
Shortness of breath, orthopnea, and a moist, productive cough are hallmark clinical manifestations of this specific type of heart failure.
What is left-sided heart failure (or left ventricular dysfunction)?
This specific class of diuretics is most frequently utilized as the initial first-line pharmacological treatment for essential hypertension.
What are thiazide (and related) diuretics?
This is the primary mechanism of action of "statin" medications, which effectively stops the liver from manufacturing its own cholesterol.
What is inhibiting the HMG-CoA reductase enzyme?
This class of drugs, which includes lisinopril's common alternative losartan, directly blocks angiotensin II from binding to smooth muscle and adrenal receptor sites.
What are Angiotensin II Receptor Blockers (ARBs)?
This routine laboratory parameter is utilized to monitor and safely titrate a continuous intravenous infusion of unfractionated heparin.
What is Activated Partial Thromboplastin Time (aPTT)?
This specific drug class, which includes beta-blockers, helps treat angina by slowing the heart rate and reducing contractility, which directly lowers myocardial oxygen demand.
What are beta-adrenergic blockers?
This specific osmotic diuretic is administered intravenously to pull fluid out of tissue and reduce elevated intracranial pressure caused by cerebral edema.
What is mannitol?
What is rhabdomyolysis?
Patients taking centrally acting antiadrenergic drugs like clonidine must be warned never to stop the medication abruptly due to the severe risk of this phenomenon.
What is rebound hypertension?
This specific lab value is the standardized metric evaluated alongside Prothrombin Time (PT) to manage oral warfarin dosing safely.
What is the International Normalized Ratio (INR)?
Before administering any dose of the cardiotonic glycoside digoxin, the nurse must perform this baseline safety assessment for one full minute.
What is counting the apical pulse rate?
Flaccid muscles, generalized muscle weakness, and cardiac arrhythmias are classic clinical manifestations indicating this specific electrolyte deficiency.
What is hypokalemia?
To prevent binding interactions that deactivate other medications, bile acid resins must be spaced out so other oral drugs are taken at least this many hours before or 4 hours after the resin.
What is 2 hours?
Concomitant use of sublingual or transdermal nitrates with phosphodiesterase inhibitors (such as sildenafil) is strictly contraindicated due to this severe cardiovascular risk.
What is profound, life-threatening hypotension?
What is Vitamin K?
Visual disturbances such as blurring and seeing yellow-green halos around lights, combined with anorexia and nausea, are core warning signs of this toxic clinical state.
What is digitalis (or digoxin) toxicity?
Because spironolactone acts as an antagonist against aldosterone, the nurse must instruct patients to strictly avoid salt substitutes containing this element.
What is potassium?
Long-term use of bile acid sequestrates can lead to a deficiency in this fat-soluble vitamin, predisposing the patient to bleeding gums and bruising.
What is Vitamin K?
To ensure proper safety and prevent the development of drug tolerance, a nurse applying a nitroglycerin transdermal patch must incorporate this practice into the daily care plan.
What is providing a patch-free interval (or rotating application sites)?
This is a primary clinical advantage that low-molecular-weight heparins (such as enoxaparin) have over traditional unfractionated heparin.
What is a more predictable therapeutic response (or not requiring frequent laboratory monitoring)?
This specific electrolyte imbalance significantly enhances a patient's susceptibility to developing digitalis toxicity, even if the digoxin level is technically within the therapeutic range.
What is hypokalemia?
