CCRN Practice Test review UPDATED
ACTUAL Exam Questions and CORRECT
Answers
what is indicated during the embolisation procedure of an AV malformation? - CORRECT
ANSWER - amicar and/or heparin. will prevent clot formation
what does the plateau pressure reflect and what is it used to calculate - CORRECT
ANSWER - lung pressure/ static (lung) complaince
peak inspiratory pressure is used to calculate - CORRECT ANSWER - dynamic (airway)
compliance)n
normal value for FSP? - CORRECT ANSWER - < 10
ARDS - what tidal volumes are appropriate? - CORRECT ANSWER - 4-5mL/kg to
prevent volutrauma
asthma patients: vent settings - CORRECT ANSWER - prolonged *expiratory* time. can
increase that on vent or decrease RR
what must be ruled out in hypercalcemia? - CORRECT ANSWER - hypokalemiabc they
may be associated. treatment is diuretic therapy but can cause life threatening arrhythmias if
hypokalemic
hypophosphatemia - CORRECT ANSWER - may be seen in etoh pts. need to watch for
hypoventilation due to muscle weakness effecting the diaphragm, also constipation and
diminished deep tendon reflexes
, what to do with sleep apnea and diminished LOC if patient is on cont and bolus PCA? -
CORRECT ANSWER - monitor pt with waveform capnography, stop continuous infusion,
administer naloxone slowly.
Ranson's criteria - CORRECT ANSWER - for pancreatitis. WBC> 16K; glucose> 200;
age > 60; LDH > 350
what is a priority assessment for MG pt? - CORRECT ANSWER - vital capacity. pts can
have diaphragm weakness and this will identify it early than other respiratory parameters
chronic stenosis of the mitral valve can cause what? - CORRECT ANSWER - left atrial
enlargement, which can then cause afib
possible etiologies of respiratory alkalosis - CORRECT ANSWER - hypoxia, pain,
anxiety. anything that increases RR
why should high airway pressures be avoided in patients with chest tubes - CORRECT
ANSWER - can cause an air leak
what intervention would the nurse anticipate for the patient with intracerebral hemorrhage -
CORRECT ANSWER - correction of coagulopathy. labetalol is drug of choice to correct
BP. surgery to evacuate in select cases.
HHNK - what is serum sodium - CORRECT ANSWER - often *LOW* due to loss in
urine.
what two things are likely to result in airflow obstruction - CORRECT ANSWER -
bronchospasm, ETT (longer and narrower diameter)

setting can cause VT or VF
