Critical care Flashcards
when is an arterial blood gas preferred over venous blood gas?
when trying to determine the patient’s oxygenation status
when measuring blood gas, the patient’s pH and Paco2 are both decreased. what is the primary process?
metabolic acidosis
a patient’s pH is decreased and paco2 is increased. what is the primary process?
respiratory acidosis
after calculating a patient’s primary pH problem on a blood gas, what is the next step?
to determine if the compensation is appropriate or if there is a mixed acid-base problem going on
if you diagnose metabolic acidosis and calculate that the Pac02 represents appropriate compensation, what is the next step to determine about the acidosis?
anion gap vs. non anion gap acidosis
what is considered an elevated anion gap?
> 12
if you diagnosed anion gap metabolic acidosis, what is the next calculation you should do?
osmolal gap
diarrhea and diuretics would cause what type of metabolic acidosis?
non anion gap metabolic acidosis
renal tubular acidosis would cause what type of metabolic acidosis?
non anion gap metabolic acidosis
methanol, ethylene glycol, DKA, lactic acidosis, uremia, and carbon monoxide will cause what type of metabolic acidosis?
anion gap metabolic acidosis
what type of metabolic acidosis can result from large volume NS infusion?
non anion gap metabolic acidosis
t/f vomiting can cause a contraction metabolic alkalosis
true
what are the two categories of metabolic alkalosis?
chloride depletion or non chloride depletion metabolic alkalosis
vomiting, diarrhea, and diuretic use lead to what type of metabolic alkalosis?
chloride depletion alkalosis
in order to know if metabolic alkalosis is chloride deplete or non chloride deplete, what study do you need to do?
urine chloride
what is the most common cause of respiratory acidosis?
chronic lung disease
which calculation is used in the case of an anion gap metabolic acidosis to see whether there is another acid base disturbance present?
gap - gap analysis
how many HPV vaccines does a 9-14 yo patient need? 15-26 yo?
9-14 yo: 2 vaccines
15-26 yo : 3 vaccines
