What are some relevant nursing actions related to the heart?
- Taking and recording a pulse, blood pressure
- Assessment of blood perfusion in patient
- Cardiac pulmonary resuscitation (CPR)
- Administration of prescribed intravenous fluids
- Electrical cardiac defibrillation
Septum
Wall or partition
Why does the heart need its own blood supply when there is blood passing through it?
It cannot receive O2 and glucose from blood passing through its chambers.
Cupis
Point
Where is your heart located?
- Inferior mediastinum, medial cavity of thorax
- Rests on diaphragm
- Apex points to left hip
How big is your heart?
Size of your fists
What does your heart do?
Pumps blood to:
1. Lungs fo oxygenations (O2) + Co2 (RV)
2. Body for transportation of gases, wastes, electrolytes, nutrients, hormones, etc (LV)
Blood from the right atrium flows THROUGH this structure.
Tricuspid Valve
What differences in pitch, duration and loudness of the two main sounds did you hear?
- First - longer, louder (tricuspid + mitral close)
- Second - Short, sharp (pulmonary + aortic close)
Blood from the left atrium flows THROUGH this structure.
Mitral Valve
Blood moves OUT of the left ventricle into this structure.
Aorta
Blood leaves the right ventricle and flows INTO this structure.
Pulmonary Trunk
Name the two components of the cardiac output.
- Heart Rate (HR)
- Stroke Volume (SV)
Location of the hearts’ pacemaker (SA node).
Right Atrium
Blood returns INTO this structure once fully oxygenated by lungs.
Left Atrium
Atria relax
Atrial Diastole
Ventricles relax, aortic and pulmonary valves close
Ventricular Diatole
What intervention(s) would address a reduction in a patient’s blood volume and blood pressure?
- Intravenous fluids
- Oral fluids
Atria contract, ventricles fill
Atrial Systole
Identify the dairy milk option below that contains less processed carbohydrate and more naturally derived nutrients, taste and satiety (feeling of fullness).
a) Homogenised, semi-skimmed
b) High calcium, lite-white
c) Reduced fat, chocolate-flavoured
d) Full cream
d) Full cream
Ventricles contract, tricuspid and mitral valves close, then aortic and pulmonary valves open
Ventricular Systole
List some factors that can influence stroke volume or heart rate.
Heart Rate:
- Temperature
- Nerves
- Hormones
- Medications
Stroke Volume:
- Venous Return Volume
- Filling time
- Contracting of myocardium
