Percutaneous coronary intervention (PCI)
balloon-tipped catheter is inserted into a coronary artery to open the artery; stents are put in place
38
how do you prepare someone for a PCI?
*Client is NPO *Premedication *Consent for the procedure *Nursing assessment
39
what does the nurse do after a PCI?
*Vital signs *Surgical site assessment *Bedrest and movement
40
complications from PCI
-bleeding from the catheter insertion site -an infection -an allergic reaction -damage to the artery from inserting the catheter damage to the kidneys -irregular heartbeat
41
client teaching after PCI
Tell your doctor if you have any of the following: -Fever or chills -Increased pain, redness, swelling, bleeding, or other drainage from the insertion site -Coolness, numbness or tingling, or other changes in the affected arm or leg -Chest pain or pressure, nausea or vomiting, profuse sweating, dizziness, or fainting
42
normal BP
<120/<80
43
elevated BP
120-129/<80

130-139/80-89
45
HTN stage 2
>140/>90
46
hypertension
BP is greater than 140/90 mmHg
47
primary HTN
no known cause
48
Secondary HTN
cause is often identified & treatable
49
Hypertension Clinical Manifestations
- Frequently asymptomatic until it becomes severe and target organ disease has occurred - Fatigue, reduced activity tolerance - Dizziness - Palpitations, angina - Dyspnea
50
what are some nursing interventions for HTN
-Lifestyle Modifications -Weight Reduction -DASH Eating Plan -Dietary Sodium Reduction -Moderation of Alcohol Intake -Physical Activity -Avoiding Tobacco Products
51
*Nursing Management for Primary Hypertension
*Health Promotion *Screening Programs *Cardiovascular Risk Factor Modification *Ambulatory Care *Home BP Monitoring *Client Adherence
52
Hypertensive crisis symptoms
severe headaches, · Sudden rise in BP associate, N/V, seizures, confusion, coma, dyspnea, anxiety, and nosebleeds
53
what are the interventions of a hypertensive crisis?
REQUIRE HOSPITILIZATION and administration of an IV antihypertensive as well as intensive monitoring
54
diagnostic assesment for HTN
· Hx and physical examination, including an ophthalmic examination · Fasting blood glucose · Routine urinalysis · Basic metabolic panel with eGFR · CBC · Serum lipid profile (total lipids, triglycerides, HDL and LDL cholesterol, total to HDL cholesterol ratio) · Serum uric acid, calcium and magnesium 12-lead ECG
55
nursing management for HTN
· Periodic BP monitoring · Nutritional therapy · Regular, moderate physical activity · Tobacco cessation · Moderation of alcohol intake · Stress management techniques · Antihypertensive drugs
56
nutritional therapy for HTN
o DASH diet o Restrict salt and sodium o Restrict cholesterol and saturated fats o Maintain adequate intake of potassium and calcium o Weight management
57
when teaching BP monitoring at home, when shoould the nurse instruct the client to take their BP
monitor first thing in the morning and before bed
58
white coat hypertension
· some patients have elevated BP readings in clinical settings
59
DASH eating plan
Fruits, vegetables, fat-free or low-fat milk, whole grains, fish, poultry, beans, seeds, and nuts
60
in patients with HTN what shoud sodium be restricted to?
2300mg/day or less
61
what are foods high in sodium that should be avoided
o Bread products o Lunch meat and cured meats o Pizza o Soup (canned products) o Sandwiches o Poultry
62
why should clients be taught to read labels of packages
food labels as well as OTC medications can contain sodium
63
physical activity and HTN
· Perform moderate intensity aerobic physically active for at least 30 minutes most days with a goal of at least 150 minutes per week
64
what is the most common side effect of antihypertensive drugs and what needs to be taught about it
· ORTHOSTATIC HYPOTENSION o Patient may feel dizzy and faint when sitting up so tell them to rise slowly to avoid falls
65
what are some things to teach a client about the side effects of diuretics
Diuretics cause dry mouth and frequent voiding o Sugarless gum or hard candy can help with dry mouth o Taking diuretics in the morning may limit voiding during the night and preserve sleep May need to supplement potassium, or avoid depending on the type of diuretic
66
assessment for CAD
· Identifying high risk persons (smoking, obese/overweight, high cholesterol, sedentary lifestyle, poor diet, diabetes, family Hx) · PQRST Assessment of Angina · Assess lipid panels
67
Precipitating factors to angina
o Physical exertion o Temperature extremes o Strong emotions o Consumption if a heavy meal o Tobacco use and environmental tobacco exposure o Sexual activity o Stimulants o Circadian rhythm patterns
68
clinical manifestaions of CAD
· Usually asymptomatic in the early stage · Chest pain with activity "HEAVINESS" (stable angina) · Can progress to unstable angina: pain at rest Lethargic/tired/run down
69
Blood tests: lipoprotein profile for CAD
o LDL (>130 mg/dL) o HDL (<40mg/dL) o Total Cholesterol (>200mg/dL) o Triglycerides (>150 mg/dL)
70
what is the gold standard diagnosic study for CAD
cardiac/heart catheterization
71
if something is found during cardiac catheterization, what is done next
coronary revascularization with percutaneous coronary intervention may be done o This is where a deflated balloon tip is inserted into the blocked coronary artery then inflated to compress the plaque against the artery wall, a stent is also usually placed Also known asballoon angioplasty
72
health promoting behaviros for CAD
· Hypertension · High serum lipids · Tobacco use · Physical Inactivity · Psychologic state · Obesity · Diabetes
73
FITT Activity Guidelines (CAD)
o Perform mild stretching for 3-5 minutes before and after activity o Perform physical activity most days of the week o HR determines the activity intensity; if patient is recovering from an MI their HR should not exceed 20 bpm o Select regular, rhythmic, repetitive activity that uses large muscles to build up endurance (walking, swimming, rowing, cycling) Session should be at lease 30 minutes long
