What will the possibility of fever have on an ABG? - ANS the pH will rise - the
oxyhemoglobin curve will be shifted to the right
What effect will the lack of icing an ABG have on the sample? - ANSit will invalidate the
sample by causing the PaCO2 to rise approx 3-10 mmHg/hr,PaO2 & pH will decrease
You are asked to draw an ABG. You prepare a glass syringe w/ heparin. What effect will
too much heparin have on the sample? - ANS it will decrease the bicarb & the PaCO2
What effect will high friction from an ABG blood draw have on the gas results? - ANS
It will decrease the PaO2 & PaCO2
Which of the following drugs are classified as a methylxanthine?
a) morphine
b) theophylline
c) prednisone
d) atropine - ANS theophylline
Your pt was admitted 3 days ago for a tension pneumothorax. What is the potential
imbalance that would be expected w/ this prolonged hypoxic state?
, lOMoAR cPSD| 65262174
a) hypochloremia
b) resp alkalosis
c) decreased bicarbonate levels
d) hypokalemia - ANS hypochloremia - chronic respiratory acidosis; kidneys will
retain bicarb (increase in bicarb levels) & decrease in chloride levels.
a student nurse asks you to explain the concept of hypoxemia. Hypoxemia is best
defined as a decrease in oxygen at
a) the cellular level
b) the alveolar level
c) levels in venous blood
d) levels in arterial blood - ANS d) levels in arterial blood
Anatomic dead space is defined as
a) conducting airway
b) wasted ventilation
c) end expiratory volume
d) minute ventilation - ANS a) conducting airway (trachea, bronchi are ventilated, but
perfusion [gas exchange] does not take place there.
The cells that are responsible for forming a barrier for alveoli are:
a) histocytes
