Q

What are the four physiological processes of nociceptive pain?

What is the electrical conductivity of the heart?

A
  1. SA node- send electrical impulses to atriums causing them to contract and expel volume of blood to ventricles
  2. AV node- gets same electrical impulse moving to…
  3. Bundle of His, down to the
  4. Bundle Branches, ending in the
  5. Purkinje Fibers- causes ventricles to contract, forcing them to expel volume of blood out into general circulation
105
Q

What is the normal or dominant pacemaker of the heart? What is the normal impulse rate?

A

Sinoatrial Node (SA Node)

60-100 beats per minute

106
Q

What is the secondary pacemaker and connects the atria and ventricles electronically? What is the normal impulse rate?

A

Atrioventricular Node (AV Node)

40-60 beats per minute

107
Q

What is the tertiary pacemaker that penetrates the atrioventricular valves and then bifurcates into the left and right side? What is the normal impulse rate?

A

Bundle of His and Purkinje Fibers

20-40 beats per minute

108
Q

How many seconds does each individual large box equal?
How many large boxes equals 1 second?

A

0.20 seconds

5 boxes

109
Q

What are the different waves on an EKG strip and what do they stand for?

A

P wave- atrial depolarization

QRS Complex- ventricular depolarization

T wave- ventricular repolarization

110
Q

What does the S1 sound in the heart represent?

A

Closure of the AV valves (tricuspid/mitral); signifies beginning of systole.

111
Q

What does the S2 sound in the heart represent?

A

Closure of the SL valves (aortic/pulmonic); signifies beginning of diastole

112
Q

What is the term for a humming vibration felt during palpation of the heart that signifies abnormal turbulent blood flow?

A

Thrill

113
Q

What is the term for an abnormal and forceful cardiac contraction, that causes a slight to vigorous movement of the sternum and rib?

A

Lift or Heave

114
Q

What are the signs and symptoms of left cardiac failure?

A

Lung issues, respiratory issues, orthopnea

115
Q

What are the signs and symptoms of right cardiac failure?

A

bulging eyes, JVD, ascites (fluid build up in abdomen), liver enlargement, peripheral edema

116
Q

What does a murmur indicate and what are the four classifications?

A

May be from a narrowed valve, malfunctioning valve, or defect in the wall of the heart

Class 1- no manifestations w/ activity
Class 2- manifestations w/ ordinary exertion
Class 3- manifestations w/ minimal exertion
Class 4- manifestations at rest

117
Q

When should a patient be concerned about weight gain?

A

More than 2 pounds a day or 5 pounds in one week

118
Q

A nurse should not administer digoxin if the heart rate is below what?

A

less than 60 beats per minute

119
Q

What does elevated levels of Creatine Kinase (CK) indicate?

A

non-specific muscle injury

120
Q

What does elevated creatinine kinase myocardial band (CKMB) indicate?

A

specific cardiac muscle injury

121
Q

What is myoglobin? What do elevated myoglobin levels indicate?

A

protein found in skeletal and heart muscles

indicates non-specific muscle break down

122
Q

What do elevated C-reactive protein levels indicate?

A

non-specific inflammation

123
Q

What does elevated brain natriuretic peptide (BNP) levels indicate? why does this indicate that?

A

used in diagnosing and predicting prognosis of heart failure

when the heart has to work harder to pump blood, it makes more BNP

124
Q

What do elevated levels of troponin indicate? What is the range of normal levels?

A

indicates cardiac injury

normal levels = 0 - 0.4ng/ml

125
Q

What are the different lab levels of BNP and what does each one indicate?

A

Normal- less than 100pg/ml

HF present- 100-300pg/ml

Mild HF- greater than 300pg/ml

Moderate HF- greater than 600pg/ml

Severe HF- greater than 900pg/ml
