ABGs
What are ABGs?
A diagnostic test is used to determine pts oxygenation status and acid/base balance.
what labs are used to diagnose a patient with Respiratory Acidosis?
ABGS
During cardiopulmonary resuscitation (CPR) for ventricular fibrillation, which drug would
an RN most likely to prepare first?
Epinephrine.
What are the normal ABG ranges?
PH 7.35-7.45
PaCO2 35-40
HCO3 22-26
If a patient is experiencing hyperventilation, which Acid-base imbalance would most likely be diagnosed?
Respiratory Alkalosis
On an ECG Each small block equals?
.04
A client with COPD is scheduled for abdominal surgery. Arterial blood gases before
surgery were: pH 7.36, PCO2 54, PO2 70. After surgery the ABGs were pH 7.35, PCO2 60,
PO2 65 on 2 L of O2. Which action should a nurse take?
a) Suction the client.
b) Have the client cough and deep breathe.
c) Administer sodium bicarbonate, per order.
d) Position the client in high Fowler's.
Mr. B came to the ED with Severe Diarrhea, which acid-base imbalance would Mr. B would most likely be diagnosed with?
Metabolic Acidosis
What is a P-Wave?
It is an Electrical impulse starting in sinus node and goes through atria, represents atrial depolarization leading to atrial contraction.
The client's arterial blood gases (ABGs) are: pH 7.32; PaCO2 48 mm Hg, and HCO3 25
mEq/L. A nurse should anticipate that an appropriate order for this client will be:
a)Incentive spirometer to be used hourly.
b) O2 via mask with a rebreather mask.
c) Antianxiety medication to slow respiratory rate.
d) Sodium bicarbonate IV to raise the pH.
A 45-year-old Female with renal failure, missed her dialysis and was feeling sick, what would be the reason?
Metabolic Acidosis
What does a QRS represent?
The depolarization of ventricles.
A nursing student asks an RN to explain the results of a client's arterial blood gases.
The results are: pH 7.43; PaCO2 30 mm Hg; and HCO3 18 mEq/L. The nurse knows the
client's acid-base status is:
Compensated respiratory alkalosis.
Name a cause of Metabolic Acidosis
Examples: Severe Diarrhea
DKA, Renal Failure, and shock.
What is preload?
Pressure from the volume of blood in ventricles at the end of diastole.
