Q

Points about the circulatory system

A

Made up of heart, blood vessels, and blood
White blood cells protect the body from bacteria, viruses, and other foreign substances
Plasma, the liquid portion of the blood, carries nutrients, waste products, hormones, salts, antibodies, and the substance necessary for the blood to clot

Q

Points about hypertension

A

Causes: hardening and narrowing of blood vessels, kidney disease, adrenal tumors, pregnancy, stress, pain, or medication
Prehypertension means that a person does not have hypertension now, but it is likely to in the future
Can lead to MI, CVA, kidney disease, or blindness
Treatment: medication, including diuretics; exercise program; diet; stopping smoking; lowering stress levels

Q

Unstable angina

A

Chest pain that occurs while a person is at rest and not exerting himself

19
Q

Nitroglycerin

A

Medication that relaxes the walls of the coronary arteries

20
Q

Points to remember about coronary artery disease

A

Cause: vessels in coronary arteries narrow after build-up of arterial plaque, reducing blood to the heart
Symptom: angina pectoris

21
Q

Care guideline for angina

A

Reduce stress
Notify the nurse immediately if the resident needs help taking his prescribed medication
Make sure resident gets enough rest
Resident should avoid big meals
Encourage resident to follow exercise plan
Resident may need to avoid hot, humid weather
Encourage residents who are quitting smoking

22
Q

Cardiomyopathy

A

A weakening of the heart muscle due to enlargement or thickening, which reduces the heart’s ability to pump blood effectively

23
Q

Points about cardiomyopathy

A

Causes: extensive CAD, heart muscle that no longer pumps effectively, virus, diabetes, thyroid problems, drug and alcohol use, birth defect, or unknown cause
Most common reason for heart transplants

24
Q

Points about myocardial infarctions

A

Cause: block of blood flow to heart muscle

25
Components of cardiac rehabilitation
Low-cholesterol, low fat, low sodium diet Regular exercise program Medication to regulate heart rate and blood pressure Blood testing Stopping smoking Avoid of cold temperatures Stress management program
26
Peripheral vascular disease
A condition in which the legs, feet, arms, or hands do mot have enough blood circulation
27
Phlebitis
Inflammation of the veins in the lower extremities
28
Anti-embolus stockings
Special stockings used to help prevent swelling and blood clots and Aid circulation; also called elastic stockings
29
Points about peripheral vascular disease
Causes: build up of arterial plaque over time, reduction in cardiac output, phlebitis Most common rule is peripheral arterial disease Symptoms: cramping in hips, thighs. Legs, or calves, cyanotic hands or feet, bluish nailbeds, arms, and/or legs that are cool to the touch, edema in hands or feet, ulcers on legs or feet, or gangrene
30
Points about peripheral vascular disease
Report: complaints of pain or change in hands, legs, or feet. Change in vital signs, increased edema, weight gain, I&O change. Headache inability to see clearly, discomfort in head, neck, jaw, shoulder, chest, or back. Disorientation, dizziness or confusion Treatment: fluid restrictions or special diets, quitting smoking, anti-embolic stockings
31
Sequential compression device
A plastic, air-filled sleeve that is placed around the leg and inflates and deflates regularly to help improve circulation, reduce fluid build-up, and prevent blood clots
32
Points about sequential compression devices
Used to improve circulation and prevent blood clots Applied during or after surgery Report damaged equipment to nurse
33
Congestive heart failure
A condition in which the heart is damaged and fails to pump efficiently
34
Orthopnea
Shortness of breath when lying down that is relieved by sitting up
35
Points about CHF
Cause: failure of heart muscle to pump effectively due to damage Symptoms: fatigue, reduction inability to be active, dyspnea, orthopnea, increased pulse, irregular heartbeat, chest pain, dizziness, confusion, weight gain, lack of appetite, edema, abdominal distention or pain, increased irritation. Symptoms associated with each side of the heart: left-sided failure: fatigue, orthopnea, coughing, rapid pulse, and weight gain
36
Points about CHF
Right-sided failure: fatigue, weakness, edema of the extremities (especially the ankles), bulging neck veins, irregular heartbeat, and fainting Treatment: medication, care plan that includes rest
37
Guidelines for CHF
``` Follow orders for activity and exercise Measure daily weight and I&O Encourage resident to follow fluid and diet orders Use social stockings, as ordered Provide extra pillow in bed Assist with ADLs ```
38
Guidelines for CHF
Assist with ROM exercises Report changes in activity levels, fatigue, dizziness, infusion, or fainting, increased respiratory rate, pulse, or blood pressure. Irregular heartbeat, palpitations, chest tightness or chest pain, dyspnea, coughing, wheezing, lack of appetite, abdominal swelling or pain, edema, bulging neck veins, weight gain from fluid retention, and change in urinary output
39
Pulmonary edema
A condition in which there is an accusation of fluid in the lungs; usually due to heart failure
40
Points about pulmonary edema
Cause: buildup of fluid in the lungs Symptoms: shortness of breath, wheezing, coughing, gurgling when breathing, anxiety, restlessness Emergency treatment is necessary
41
Anemia
A condition in which the amount of red blood cells or hemoglobin in the body is less than normal
42
Hypoxia
A condition in which the body does not receive enough oxygen
43
Points about anemia
Cause: amount of red blood cells or hemoglobin in the body is less than normal Symptoms: fatigue, weakness, pale skin, problems with the tongue, brittle nails, difficulty concentrating Treatment for iron-deficiency anemia: diet of foods rich in iron, vitamins, iron supplements, and methods to treat constipation that can occur
