PCCN Practice Exam 2 Questions and
Answers Latest Study Guide
What can worsen patient's outcome following an ischemic stroke? -
✅ Fever, Hyperglycemia, and low sodium can worsen a patient's outcome following an ischemic
stroke.
What is the adverse effect of ACE inhibitors? -
✅ Dry, Hacking Cough.
Stop the medication and do not administer.
What is happening in severe sepsis? -
✅ Decreased preload due to blood vessels vasodilate capillary leaks and volume depletion.
Volume resuscitation is a priority in severe sepsis and septic shock.
What are the signs of anxiety? -
✅ Nausea, diarrhea, and shortness of breath.
What treatment options prevent atelectasis or new breath sound changes after abdominal surgery?
-
✅ Chest X-ray and Pulmonary Hygiene.
What might cause a change of level of consciousness with a closed head injury? -
✅ If the patient's neuro assessment has changed from their typical baseline, it is due to an
increased intracranial pressure.
The difference between right axis, extreme right axis, and left axis deviation of the heart's electrical
triangle system -
✅ Left axis deviation: Positive deflection QRS in Lead I. Negative deflection QRS in lead aVF.
Extreme Right axis deviation: Negative deflection QRS in Lead I. Negative deflection QRS in lead aVF.
Right axis deviation: Negative deflection QRS in lead I. Positive deflection in lead aVF.
, Normal Axis deviation: Both positive deflection in lead I and aVF.
Patient with pancreatitis is showing Chvostek's sign. What lab finding may be affected? -
✅ Calcium serum level below 8.5
How does the S4 heart sound occur with ventricular hypertrophy? -
✅ The ventricles are too thick, and it is difficult to adequately fill the ventricles. The atria make a
forceful contraction. The sound and vibration of the ejection make the S4 heart sound.
Exclusion criteria for rTPA (recombinant tissue plasminogen activator) -
✅ -active internal bleeding (an example is GI BLEED)
-acute bleeding
-surgeries within the past 3 months.
Early signs versus late signs of increased intracranial pressure -
✅ Early signs: Change of mental status, ↓ LOC
Late signs: Slurred speech, nystagmus, pupil inequality is a sign of impending herniation.
What is the ominous sign of acute asthma exacerbation going in to acute respiratory failure? -
✅ Hypercapnia or elevated PaCO2.
