Study Notes
Orthostatic Hypotension
- Arterial pressure drop upon standing indicates orthostatic hypotension.
Blood Distribution
- The majority of blood in the body is found in the venous system.
Cardiac Afterload
- Dilation of arterioles leads to a decrease in cardiac afterload.
Administering BiDil
- Isosorbide dinitrate/hydralazine [BiDil] is primarily administered to African American patients.
Compensatory Responses
- In patients with reduced cardiac output, the renin-angiotensin-aldosterone system (RAAS) is activated.
Effective Heart Failure Treatment
- Absence of neck vein distention when the head of the bed is elevated indicates a therapeutic effect in heart failure patients.
Priority Nursing Interventions
- Before administering digoxin, analyze heart rate and rhythm as a priority intervention.
Pulse Assessment
- Assessing the pulse is crucial prior to administering digoxin to patients with heart failure.
Digoxin Administration
- If a patient's pulse is 55 beats/min, withhold the digoxin dose.
Blood Pressure and Vessel Constriction
- Constricting blood vessels will elevate blood pressure.
Biochemical Parameters for Digoxin
- Serum potassium concentration should be assessed to ensure safe administration of digoxin.
Sympathetic Nervous System Response
- In failing hearts, increased sympathetic activity results in tachycardia.
Preload Assessment
- A decrease in preload indicates a reduction in end-diastolic volume.
Cardiac Output Determinants
- Heart rate must also be assessed alongside stroke volume to determine cardiac output accurately.
Effects of Vasoconstriction
- Medication that constricts blood vessels increases vascular resistance.
Captopril Effects
- Captopril works by blocking the production of angiotensin II in patients with heart failure.
