Cardiac Medications Flashcards
common site for ABG
Radial Artery
ABG type and size of syringe
10mL heparinized syringe
why do they use heparinized syringe in ABG analysis?
anticoagulant to prevent bleeding
What is done to assess collateral circulation of the hand?
Allen’s Test
Normal return to pinking color during ABG analysis?
6 seconds
ABG: Where to place specimen?
container with ice to prevent hemolysis or breakdown of RBC
How to do an ABG analysis?
- Occlude radial and ulnar artery
- Close and open hand until blanch
- Release ulnar artery
- Wait for 6s for the return of pinkish color
*Less than 6seconds indicates decrease collateral circulation of the hand

Primary Risk Factor of Respiratory Acidosis
COPD
Clinical Manifestations of Respiratory Acidosis
Headache
Hypercapnia
Warm and flush skin
Tachycardia
Blurry Vision
Irritability
Decrease level of consciousness
Late sign of respiratory Acidosis
Disorientation and Confusion
Management for Respiratory Acidosis
Maintain patent airway: 2-3 lpm (Venturi mask)
Give medications as prescribed
Administer o2 as ordered
Perform tracheal suctioning, postural drainage, coughing, and deep breathing
*Hyperoxygenate before and after
Interval for tracheal suctioning
15 minutes Max time
20-30 minutes before re-inserting
Chest physiotherapy nursing considerations
15 minutes
Upon awakening
Before meals
At bedtime
*After meals causes aspiration
most common cause of respiratory alkalosis
Panic Attack/ Anxiety
Manifestations of respiratory alkalosis
Tachypnea
Anxiety
Restleness
Lightheadedness
Paresthesia
Increase deep tendon reflex
(+) Trousseau and Chvostek sign
Convulsion and seizure
hyperventilation management
breathe into brown paper bag
hypoventilation management
pursed lip breathing
most common causes of metabolic acidosis
renal failure and diarrhea
metabolic acidosis manifestations
breathing is rapid and deep (Kussmaul’s breathing)
SOB or dyspnea
Headache
metabolic acidosis ECG reading
peaked T wave
Prolonged PR Interval & QRS duration
Initial signs of metabolic acidosis
paresthesia, high and fast > diarrhea
late sign of metabolic acidosis’’
muscle weakness
Management for metabolic acidosis
Na HCO3 per IV (alkalinizing solution)- to reduce the effects of the acidosis on cardiac function. Flush it with NSS
Management for metabolic acidosis esp. for renal failure
Dialysis
Metabolic Alkalosis is caused by
loss of H production due to excessive vomiting
commonly associated with the use of diuretics because of hydrogen ion loss from kidneys
manifestations of metabolic alkalosis
electrolyte imbalance
disorientation/ confusion
muscle twitching
paresthesia
headache
nausea/ vomiting
metabolic alkalosis late sign
tremor and convulsion
management for metabolic alkalosis
Adm. 02 as ordered
Seizure precautions
Maintain patent IV
Adm. diluted K solution w/ am infusion pump
Monitor I and O
Metabolic alkalosis drug management use to increase excretion of HC03
Diamox
What is the IV solution for the management for metabolic alkalosis. This solution is infused no faster than 1L over 4hrs.
Ammonium Chloride
*Don’t adm. to patients with hepatic or renal disease
Arterial Disorder
Reynaud’s Disease
Venous Disorder
Deep Vein Thrombosis
Pain; intermittent claudication aggravated by activity and exercise
Reynaud’s Disease
Reynaud’s Disease Manifestations
Thin, shiny skin in the legs
Loss of hair on the affected leg
Skin is cold to touch
Ulcers occur in toes
Gangrene may develop
DVT pathognomonic Manifestation
Homan’s sign > positive calf pain
DVT s/sx
pain is improved by activity and exercise
brown pigments around ankles
Redness of skin with edema
skin is warm to touch
ulcers occur in ankle
gangrene does not develop
*phlebitis
what triad is the cause of DVT
Virchow’s triad
- vessel wall injury
- venous stasis
- hypercoagulability of the blood
