Q

Heart Location and Structure:

what is the function of the heart valves?

A

The heart has four valves that prevent the backflow of blood. These valves are the
1. tricuspid (right AV valve): prevents backflow into the R atrium
2. mitral (left AV valve): prevents backflow into the L atrium
3. pulmonic (right SL valve): prevents backflow into the R ventricle
4. and aortic (left SL valve): prevents backflow into the L ventricle

Tricuspid valve:
- when the R ventricle contracts, the tricuspid valve closes to prevent backflow into the R atrium
- Instead, blood is pushed forward into the pulmonary artery

Pulmonary valve:
- after the R ventricle contracts & pumps blood into the pulmonary artery, the pulmonary valve clsoes to prevent backflow into the R ventricle

Mitral (biscuspid) valve:
- when the L ventricle contracts, the mitral valve closes to prevent backflow into the L atrium.
- this ensures that blood is pumped forward into the aorta

Aortic Valve:
- after the L ventricle contracts & sends blood into the aorta, the aortic valve closes to prevent backflow into the L ventricle

Q

Blood flow

Describe the path of blood flow through the heart, distinguishing between pulmonary and systemic circulation.

A

Pulmonary Circulation:
1. Deoxygenated blood travels from the body into the right atrium (RA), then to the right ventricle (RV).
2. It’s pumped from the RV to the lungs via the pulmonary artery to receive oxygen

Systemic Circulation:
1. Oxygen-rich blood returns from the lungs to the left atrium (LA), then goes to the left ventricle (LV).
2. The LV pumps this oxygenated blood out to the body through the aorta

“VC, RA, RV, PA,
Lungs give air, send it LA,
LV, AO, body all day!”

Q

Cardiac Conduction

What does the term “automaticity” refer to in the context of the heart?

A

Automaticity means the heart has the inherent capacity to contract independently, without external signals, thanks to its electrical conduction system
- means the heart can contract on its own without needing external signals from the brain or nerves.
- This happens because of the heart’s electrical conduction system, which controls the heart’s rhythm.

Q

Cardiac Conduction

Outline the pathway of electrical impulse conduction in the heart.

A
  1. The electrical impulse originates in the SA node.
  2. It then travels through the atria to the AV node, continuing down the Bundle of His.
  3. The impulse then spreads through the bundle branches to the ventricles, causing them to contract.

SA Node → “SAy Aye” (It’s the pacemaker, starting the signal)
AV Node → “AVengers” (The AV node pauses, like superheroes planning the next move)
Bundle of His → “Bundle Up” (Like preparing for the next step)
Right and Left Bundle Branches → “Let’s Branch Out” (The signal branches into two paths)
Purkinje Fibers → “Purk the Party!” (Purkinje fibers fire, and the ventricles contract, finishing the job)

Q

What does an electrocardiogram (ECG) record?

A

An ECG records the electrical activity of the heart.
- The characteristic PQRST waves seen on an ECG represent the different phases of the cardiac cycle.

P → Atria Push
(P wave: Atrial depolarization, atria contract to push blood into ventricles)
QRS → Quick Response
(Ventricular depolarization, ventricles rapidly contract to pump blood out)
T → Then Reset
(Ventricular repolarization, ventricles reset to get ready for the next beat)

Q

Define cardiac output.

A

Cardiac output is the volume of blood the heart pumps out (ejects) every minute.
* It is calculated by multiplying stroke volume (the amount of blood ejected with each beat) by heart rate (the number of beats per minute)

Q

what is preload

A

Preload refers to the amount of blood in the ventricles at the end of the diastole phase, which is when the ventricles are relaxed and filling with blood.
- It’s also a measure of the stretching of the ventricular walls.

Q

What are the primary factors influencing cardiac output?

A

Four key factors influence cardiac output:
1. preload
2. afterload
2. heart rate,
3. and the heart’s ability to contract effectively (contractility).

Pump → Preload (How much blood fills the heart before it pumps)
Push → Afterload (The pressure the heart must push against to pump blood out)
Pace → Heart Rate (The speed or pace at which the heart beats)
Power → Contractility (The strength or power of the heart’s contraction)

Q

Heart sounds

Paradoxical splitting

A
  • During expiration (breathing out), the pulmonary valve closes first and the aortic valve closes later, creating the split.
  • This is abnormal and can happen with conditions like left bundle branch block or aortic stenosis, where the left side of the heart takes longer to contract, delaying the closure of the aortic valve.

L bundle branch block:
- In left bundle branch block, the delay in the electrical signal causes the left side of the heart (and the aortic valve) to work more slowly, making the aortic valve close after the pulmonary valve.

Aortic stenosis:
- In aortic stenosis, the narrowed aortic valve causes a delay in closure, so the aortic valve closes later than the pulmonary valve.

Q

Heart sounds

physiologic splitting

A
  • In physiologic splitting, during inspiration (when you breathe in), you hear two distinct sounds within S2 because the aortic valve closes first, followed by the pulmonary valve.
  • This splitting is normal and happens because more blood flows into the lungs during inspiration, delaying the closure of the pulmonary valve slightly.

Q

valvular disorders

aortic regurgitation

A

the leakage of blood going back into the left ventricle from the aorta (instead of going to the rest of body)

Effects:
1. the L ventricle has to handle a larger volume of blood d/t backflow, leading to L ventricular dilation (enlargement of L ventricles)
2. L ventricle weaken & can fail over time = HF

S/S:
* may be asymptomatic in early stages
* as the condition progresses, symptoms can include:
1. SOB
2. fatigue
3. palpitations
4. swelling in legs & ankles

SOB
- as the heart weakens, fluid builds up in the lungs (pulmonary congestion), making it harder to breathe

Fatigue
- u feel tired bc the heart is not pumping blood efficiently, meaning less O2 is getting to ur muscles & tissues

Palpitations
- the extra amt of blood in the L ventricle makes the heart work harder & faster
- this increased workload can = irregular HB (palpitations) that are more noticeable when lying down/at night

Swelling in legs & ankles
- when the L side of the heart weakens, it can lead to fluid buildup thruout the body bc BF slows down, esp in the lower extremitites

Q

valvular disorders

aortic stenosis

A

calcification narrows the aortic valve, restrictsing blood flow from the L ventricle to the aorta.

Effects:
* the L ventricle has to work harder to pump blood thru the narrowed aortic valve (to the body) = L ventricular hypertrophy (thickening of heart muscle)
* L ventricle eventually weakens = HF

S/S:
1. chest pain
2. SOB
3. fatigue
4. dizziness
5. fainting

Chest pain (angina):
- the narrowed aortic vave & the reduced BF to the coronary arteries (which supply the heart) deprives the heart of O2 = chest pain esp during exertion

SOB:
- as the L ventricle becomes thicker from working harder to pump thru the narrows valve, it becomes weaker and causes blood to back up into the lungs & making it diff to breathe

Fatigue:
- less O2 rich blood reaches the muscle & organs d/t narrowed aortic valves

Dizziness:
- the brain not getting enough o2 d/t restricted BF out of the heart

Fainting (Syncope):
- drop in BF to the brain = fainting d/t the heart not being able to pump enough blood to maintain enough BP

A

CAD is atherosclerosis of the coronary arteries. It can lead to angina, heart attack, and heart failure.

108
Q

What should you ask about in the History of Present Illness?

  3. type of pain
  4. location
  5. aggravating/relieving factors
  6. and associated symptoms.

For example, with chest pain, ask about type, location, radiation, intensity, and associated symptoms (like nausea or sweating).

109
Q

What should you ask in the Past Medical History for cardiovascular assessment?

A

Ask about any history of
1. hypertension
2. hyperlipidemia
3. diabetes
4. heart attacks
5. strokes
6. past surgeries, or hospitalizations related to the heart.

110
Q

Why is a detailed medication history important in cardiovascular assessments?

A

Pay attention to meds that affect cardiovascular function such as:
1. antihypertensives
2. antiarrhythmics
3. anticoagulants
4. prescription, over-the-counter drugs, and herbal supplements.

111
Q

Why is it important to document allergies?

A

Document medication, food, or environmental allergies to prevent adverse reactions during treatment.

112
Q

What family history should you gather in cardiovascular assessment?

A

ask about
1. coronary artery disease
2. hypertension
3. stroke
4. or sudden cardiac death in immediate family as these increase the patient’s risk

113
Q

What lifestyle factors are relevant in the Social History for cardiovascular assessment?

A
  1. Smoking
  2. alcohol consumption
  3. diet, exercise
  4. and stress levels

as these significantly influence cardiovascular health.

114
Q

What are the key vital signs to monitor in cardiovascular assessment?

A
  1. Blood Pressure: Check in both arms for any difference, high BP may indicate hypertension.
  2. Heart Rate: Note rhythm, tachycardia (>100 bpm) or bradycardia (<60 bpm)
  3. Respiratory Rate: Increased rate may suggest heart failure.
  4. Temperature: Look for signs of infection/inflammation.
  5. Oxygen Saturation: Low levels suggest poor cardiac output or pulmonary congestion.
115
Q

What do you inspect during a cardiovascular assessment?

A

1) General Appearance:
* Look for signs of distress, cyanosis, pallor, or edema.

2) Skin:
- Check for cold, clammy skin (suggests poor perfusion).

3) Chest:
- Inspect for visible pulsations, heaves, or lifts (may indicate heart enlargement).

4). Extremities:
- Check for edema, especially in lower extremities (could be right-sided heart failure).

5) Jugular Venous Distention (JVD):
- Assess for JVD, a sign of increased right atrial pressure.

116
Q

How do you assess the Carotid Arteries?

A

Gently palpate one artery at a time to assess
1. pulse rate
2. pulse rhythm
3. pulse amplitude
4. and pulse contour

avoiding excessive pressure.

117
Q

What is the Apical Impulse (PMI) and how do you assess it?

A

The PMI is the point where the left ventricle is felt against the chest wall.
- Palpate at the 5th intercostal space, left midclavicular line, and note its location, size, and amplitude.

118
Q
A
119
Q

What are you listening for when auscultating heart sounds?

A

Listen at all four auscultatory areas (aortic, pulmonic, tricuspid, mitral) for S1 and S2, noting intensity, any splitting, extra sounds (S3, S4), clicks, or snaps.

120
Q

What should you assess if a murmur is detected?

A

Determine its timing (systolic or diastolic), location, intensity, pitch, pattern, and quality to aid in diagnosis.

121
Q

What does an ECG help diagnose?

A

It records the heart’s electrical activity to diagnose
1. arrhythmias
2. conduction abnormalities
3. and myocardial ischemia.

122
Q

What does an echocardiogram assess?

A

It uses ultrasound to visualize the heart, checking
1. chamber sizes
2. valve function
3. ejection fraction
4. and wall motion abnormalities.

123
Q

Why is a chest X-ray useful in cardiovascular assessment?

A

It assesses the size and shape of the heart and the condition of the lungs.

124
Q

What blood tests are important in cardiovascular assessment?

A

Cardiac enzymes (troponin, CK-MB), lipid profile, and complete blood count (CBC) help assess heart function and identify risk factors for cardiovascular disease.

125
Q

What is a possible nursing diagnosis for cardiovascular issues?

A

Diagnoses might include Decreased Cardiac Output, Ineffective Tissue Perfusion, or Activity Intolerance.

126
Q

What are key interventions for a patient with a cardiovascular condition?

A
  1. Monitor vital signs and oxygen saturation.
  2. Administer medications as prescribed.
  3. Educate on heart-healthy lifestyle changes (diet, exercise).
  4. Provide emotional support and manage anxiety.
127
Q

How do you evaluate the effectiveness of cardiovascular nursing interventions

A

Continuously assess the patient’s vital signs, symptoms, and response to treatment, modifying the care plan as needed.

128
Q

What are special considerations for cardiovascular assessment in pregnant women?

A

Be aware of potential complications like gestational hypertension and preeclampsia due to the cardiovascular changes during pregnancy.

129
Q

What are cardiovascular concerns in infants and children?

A

Assess for
1. developmental milestones
2. feeding difficulties
3. and signs of congenital heart defects.

130
Q

What are important considerations for older adults in cardiovascular assessment?

A

Be mindful of age-related changes like
* decreased cardiac output
* and increased risk of atherosclerosis.
