2024 CCRN EXAM QUESTIONSWITH CORRECT ANSWERS
Which of the following sign or symptom is most specific to a small-bowel
obstruction? - CORRECT-ANSWERSVomiting of fecal matter
Remember that time is muscle, so reperfusion is the priority. Also remember
an actual problem (decreased contractility) takes priority over a potential
problem (dysrhythmias) T/F? - CORRECT-ANSWERSTrue
patient returns to the critical care unit after insertion of a transvenous
pacemaker. There are pacing spikes not followed by a QRS. Which of the
following is a method to facilitate capture during pacing? - CORRECT-
ANSWERSIncrease milliamperage
Consider that failure to capture occurs when the electricity from the
pacemaker does not cause depolarization of the ventricle (or atria if an atrial
pacemaker). It would be logical to consider using more electricity (i.e.,
milliamperage).
Which of the following statements about colloids is correct? - CORRECT-
ANSWERSThey increase intravascular colloidal oncotic pressure.
She has had a craniotomy to evacuate the clot, and an intraventricular
catheter was placed during surgery. While the nurse is monitoring the
patient's intracranial pressure (ICP), the pressure climbs to 40 mm Hg but
returns to 15 mm Hg almost immediately. This describes which of the
following? - CORRECT-ANSWERSB wave
Normal ICP has a pressure of 5 to 15 mm Hg. An elevation of ICP to 20 to 50
mm Hg occurring every 30 seconds to 2 minutes is a B wave. An elevation of
ICP to 50 to 100 mm Hg lasting longer than 2 minutes is an A wave. An
elevation of ICP to 20 to 25 mm Hg every 4 to 8 minutes is a C wave.
What three things tell you heart catheter has flipped back into right
ventricle? - CORRECT-ANSWERSThree things tell you that the catheter has
flipped back into the right ventricle: drop in diastolic pressure, loss of dicrotic
notch, and initiation of ventricular ectopy.

Continue insulin infusion until acidosis is resolved
Characteristics of HHNK: - CORRECT-ANSWERSOlder
Type 2 diabetes
Pancreatitis
>600 blood sugar
Insulin production: Yes
Serum K: Often elevated due to insulin deficiency
, Tx for HHNK: - CORRECT-ANSWERSFluids, insulin
