Perfusion Flashcards
HF alternative intervention
I and O, O2, BNP level, discharge info, assess respiratory lung function every 2-4 hrs
HF not improving
urine is 160 mL over 8 hrs and wheezing
Fetal HR 120 base and accell 135. The contract is 110-120
this is a normal document.
What does someone with bad perfusion look like in one word?
Crap (pale, diaphoretic, labored breathing)
What are some factors that impact perfusion?
- obesity
- trauma
- fevers
what does preload measure
Volume
What does afterload measure?
pressure
What are some signs of poor perfusion?
- confusion
- hypotension
- Dyspnea
- Decreased or absent pulse
- Pulmonary congestion
- Chest pain
- Low urine output
- Edema
- Cool,pale skin
- Cyanosis
What is the cardiac output formula?
CO= SV X HR
What is the threshold number for hypertension?
140/90 or higher
What are people with hypertension most at risk for?
CHD, HF, stroke, and renal failure
What factors can affect BP?
- temperature
- diet
- race
- gender
- age
- weight
- time of day
- position
- exercise
- emotional state
What are some factors that influence BP
- inflammatory mediators

When is someone in a hypertensive emergency?
BP> 180 systolic
>120 diastolic
What people are more likely to have HTN?
- middle-aged and older adults
- Blacks mores than whites and Hispanics
- In whites more males than females
- in blacks more females than men
What is one of the first signs of HTN?
Wake up with a headache but it goes away as the day goes on
What are some risk factors for HTN?
- family history
- age
- race
- mineral intake
- obesity
- insulin resistance
- excess alcohol consumption
- stress
What can someone do to their mineral intake to reduce their risk for HTN?
Reduce their sodium take and check the labels
What are some different diagnostics used to diagnose HTN?
- ECG
- Urinalysis (protein in the urine can indicate HTN
- Blood glucose
- Hematocrit
- Serum K+, creatinine, calcium
- Cholesterol and lipoprotein profile
What are some lifestyle modifications for HTN?
- diet
- reduced sodium intake
- maintain calcium and K+ intake
- Reduce saturated fats
- weight loss
- physical activity
- reduce/stop alcohol and smoking use
- stress reduction
If someone with HTN is on their BP meds, what should a nurse look for?
Orthostatic hypotension
If a patient with HTN is having falling problems what might be going on?
orthostatic hypotension from meds
How would you check for orthostatic hypotension?
wait 2 minutes between sitting and standing to check BP
How often should someone exercise to decrease their risk of HTN?
5 or more days/week
