Arterial Ulcer – Pale, deep base, surrounded by tissue that is cool with trophic changes such as dry, soluble skin and loss of hair. Cause by ischemia from inadequate arterial blood supply of oxygen and nutrients .
Venous stasis Ulcer – Dark, red base, surrounded by skin that is brown in color with edema. Caused by the accumulation of waste products of metabolism that are not cleared due to venous congestion.
Stage I Ulcer – Reddened area with intact skin surface.
Management of DVT – Bed rest, limb elevation , relief of discomfort with warm, moist, heat and analgesics (Tylenol, not narcotics) prn. Ambulation is contraindicated.
Sclerotherapy – Injection of a sclerosing agent into a varicosity. The agent damages the vessel and causes aseptic thrombosis that result in vein closure. With no blood flow thru the vessel, distention will not occur. The surgical procedure for varicose veins is vein ligation and stripping: tying off the varicose veins and large tributaries and then removal of the vein with the use of hooks and wires via multiple small incisions in the leg
Cardiac Tamponade – Tachycardia, muffled of distant heart sounds, JVD, a falling BP accompanied by pulsus paradoxus (a drop in BP on inspiration of more than 10mm Hg)
Self care of an ischemic leg ulcer – Same as Peripheral Arterial Disease / Diabetes Mellitus
Sodium containing – Toothpaste, mouthwash, OTC meds such as analgesics, antacid, laxatives, and sedatives. Softened water and some mineral water. Fresh fruits and vegetables are low in sodium,
INR – Normal 2.0 – 3.0
Should be 2.0 to 3.0 for anticoagulant therapy (Coumadin)
Should be 2.5 to 3.5 for Mechanical prosthetic heart valve patients and survivors of acute MI
IABP therapy for Cardiogenic Shock. Contraindicated for aortic insufficiency or aortic or thoracic aneurysms. Not used for CHF or pulmonary edema.
Atrial fibrillation with ventricular rate of 150? Check for hypotension!! Patient is at risk for decreased cardiac output due to loss of atrial kick. Assessment includes palpitations, chest pain or discomfort, hypotension, pulse deficit, fatigue, weakness, dizziness, syncope, SOB, and distended neck veins.
RSHF – Peripheral and sacral edema, JVD, and organomegaly. LSHF – Lung sounds, rales at the bases.
Quinidine Sulfate for treatment of atrial fibrillation or atrial flutter – Only given after client has been digitalized. Take exactly as prescribed, do not chew the extended release capsules or open the capsules and mix them with food. Wear a Medic-Alert bracelet and to continue taking digoxin as prescribed
PR interval – Impulse from the atrial to the ventricles: Normal is 0.12 to 0.20 seconds
Ventricular tachycardia – Check for client’s unresponsiveness. This way you can determine if the client ifs affected by the decreased cardiac output caused by the VT state
