First line hypertension medications?
Thiazide diuretics (HCTZ)
ACEs
ARBs
CCBs
Which systems help regulate blood pressure? (4)
Sympathetic nervous system, RAAS, baroreceptors, vascular endothelium
Explain DROWNS and SWELLS. Which one belongs to right sided and left sided HF?
DROWNS- left sided
Dyspnea, rales, orthopnea, weakness, noctural dyspnea, sputum (pink/frothy)
SWELLS- right sided
swollen legs, weight gain, edema, liver enlargement, large neck veins (JVD), stomach distention (ascites)
mmk so how in the world do we manage a hypertensive crisis (EMERGENCY!)?
IV drugs titrated SLOWLY
we dont want MAP reduction more than 25% in the first few hours
the body is used to that high bp, so if we drop it too fast we risk vital organs not perfusing correctly
do you love ellie be honest
ok phew i thought youd say no
Give me the stages of blood pressure NEOW (just normal, 1 and 2)
Normal: <120/80
stage 1: 130-139/80-89
stage 2: >=140 or >=90
Acute care of chronic stable angina?
Position upright; apply oxygen
Assess: VS, heart & breath sounds
Continuous 12 lead EKG monitoring
Pain relief (NTG; IV opioid if needed)
Obtain cardiac biomarkers (troponin?)
Obtain chest xray
Provide support; reduce anxiety
Patient teaching
Treatment approach to stage 1 hypertension?
lifestyle modifications for 3-6 months, then if still high move to medications. (one first line drug + lifestyle changes)
Explain biventricular failure.
both right and left ventricular dysfunction.
fluid build up and venous engorgement, decreased perfusion to vital organs, inability for both ventricles to pump effectively
Nursing care & non pharmacologic management of HF?
DAILEY WEIGHTS!
fluid monitoring
low sodium diet
MEDICATION COMPLIANCE
close lab monitoring (electrolytes, liver, renal)
edema monitoring
Nursing assessment of hypertension?
Detailed family history
Dietary habits
Physical activity level
Weight history and body consumption
Alcohol consumption
Sleep patterns and quality
Stress lvels and coping mechanisms
Second line hypertension meds?
Diuretics (loop, K sparing)
Beta Blockers
Alpha 1 blockers
Centrally acting drugs (alpha antagonists, clonidine, guanfacine)
What is target SBP for the elderly?
<130mmHG
ok so we know the patient has ACS, what diagnostics do we do?
detailed health history
12 lead ECG (we're looking for how old ecg compares to new one, changes in QRS complexes, ST segments, T waves, because this is gonna help us determine if its STEMI or NSTEMI)
chest xray (can show signs of HF)
Difference between hypertensive crisis and urgency?
Crisis is an EMERGENCY! Target organ damage! Hospitalization! GET DAT PATIENT CURED STAT (SBP>180 and/or DBP >120 )
Urgency isnt great, but more common. Usually no hospitalization required and no target organ damage. ASSOCIATED WITH CHRONIC STABLE DISORDERS.
Most common death in US?
CAD :(
Myocardial infarction (acute coronary syndrome) clinical presentation?
Severe chest pain not relived by rest, position change, or nitrate administration
pts feel a crushing, heaviness, pressure, tightness, or burning sensation
Radiating pain is also common to neck, jaw, arms, back. substernal or epigastric regions are most commonly where they are felt
often occurs in the morning time and greater than 20 min in duration
Outpatient care of chronic stable angina?
Stress testing, cardiac cath, CTA, echocardiogram
serum cardiac biomarkers for ACS diagnostics GO!
Troponins, CK-MB, myoglobin
cardiac specific troponin is best indicator for MI (Cardiac specific troponin T & cardiac specific troponin I)
Increased 4-6hrs after onset of MI, peak 10-24hrs after, return to baseline 10-14days
BIOMARKERS NEGATIVE FOR UA; POSITIVE FOR NSTEMI
preload
afterload
myocardial contractility
HR
STEMI v NSTEMI?
STEMI-
total, prolonged blockage causing heart muscle damage
requiring immediate emergency intervention (angioplasty or thrombolytics)
ST segment elevation
NSTEMI-
partial or temp blockage
ST segment depression or T wave inversion
causes damage to inner layer of heart
treated w/ meds first, cardiac catherization within 24-48hrs
Treatment for STEMI v NSTEMI?
STEMI:
Treatment approach to stage 2 hypertension? (or if stage 1 with other comorbidies)
Two drugs from different classes plus lifestyle modifications. Requires more frequent follow up than stage 1
What assessments and test do nurses utilize for heart failure?
Assessments:
vital signs
lung sounds
heart, rate and rhythm
extremities, cyanosis and edema
weight, usual daily
abdominal swelling
JVD
i&os
Tests:
chest xray
cardiac cath
brain natriuretic peptide
cardiac enzymes
CBC, CMP
echocardiogram
management of ACS?
IMMEDIATE:
ABCs, ADPIE, MONA
ADDITIONAL:
dual antiplatelet therapy, anticoagulation, beta blockers, ACE/ARBs, statins
