ADULT CCRN CERTIFICATION EXAM
EXPLAINED(AACN QUESTIONS AND ANSWERS
2022/2023)
A nurse knows that research supports a patient having unrestricted access to his or her support person.
However, the nurse's unit restricts all patient visitors to set times. The best response would be?
A. Gather facts and propose a policy change to the manager for the unit
B. Tell the patient that the unit's policy is outdated but there is nothing that can be done.
C. Continue to follow the unit policy
D. Complain to colleagues about the unit's policy (correct answer)A. Gather facts and propose a policy
change to the manager for the unit.
Cardiac Tamponade s/s (correct answer)-Narrowing pulse pressures
-Equalization of the right and left heart pressures
-Pulsus paradoxus
-Enlarged heart on chest x-ray
ECG changes with STEMI that affect the lateral wall?
A. II, III, aVF
B. V1, V2, V3
C. V2, V3, V4
D. V5, V6, I, aVL (correct answer)D. V5 and V6 represent the lower lateral wall of the left ventricle and I
and aVL represent the high lateral wall of the left ventricle, supplied by the left circumflex artery in most
of the population
DIC laboratory findings (correct answer)Increased PT and PTT, fibrin split products, D - dimers.
, -DIC is a clotting problem, with massive coagulation. As clots break down, firing split products are
produced.
Rhabdomyolysis & Acute Tubular necrosis (correct answer)Rhabdomyolysis (destruction of skeletal
muscle cells) results in the release of massive amounts of creatinine kinase that in turn may "clog" renal
tubes and lead to acute tubular necrosis
Prerenal Failure (correct answer)Produced by conditions that decrease renal perfusion and is most
common cause of community acquired acute renal failure (70%).
*BUN to creatinine ratio at least 20:1
Intrarenal Failure (correct answer)direct damage to the kidneys by inflammation, toxins, drugs,
infection, or reduced blood supply
BUN to creatinine ration at least 10:1
A patient w/ a history of HLD and ETOH abuse reports LUQ pain. The patients VS are as follows: Temp-
38.3C, BP-85/50, HR-110, R-24. What lab values would the nurse anticipate?
A. Decreased serum amylase lvl and increased WBC
B. Decreased Hct and increased lipase lvl
C. Decrease sedimentation rate and elevated Calcium lvl
D. Increased LDH and increased SGOT (AST) (correct answer)B. Decreased Hct and increase Lipase lvl
-Represents acute pancreatitis, with the LUQ pain and increase lipase levels that are commonly seen in
patients with pancreatitis
Placement of a patient with unilateral PNA. (correct answer)Place the "good lung" down and have the
patient on the side that doesn't have a problem.
-This is because more blood perfusion is greater to the "down" side due to gravity. If more blood goes to
the bad side, hypoxemia may occur.
