PASS CCRN TEST BANK QUESTIONS & ANSWERS
100% CORRECT LATEST VERSION
1. Which of the following would be the earliest auscultatory finding in left
ventricular failure (LVF)?
A. Crackles
B. S3
C. Murmur of mitral regurgitation
D. Pericardial friction rub
Answer: B. S3
LVF would be the most subtle because early changes are usually subtle changes. Choose "S3."
2. A patient with a triple-lumen subclavian catheter has been receiving total
parenteral nutrition, maintenance fluids, and antibiotics by the catheter. He has been
slightly confused. Suddenly he grasps the catheter and pulls it out. He then
complains of shortness of breath, and his pulse oximetry indicates an SpO2 of 84%.
How should this patient be positioned?
,A. Head down, left side
B. Head down, right side
C. Head of bed elevated, left side
D. Head of bed elevated, right side
Answer: A. Head down, left side
Envision a big air bubble in the patient's heart. Think: what position would decrease the movement of the air embolism out
of the right side of the heart. Chose "Head down, left side."
3. Oxygen delivery (DO2) is the product of which of the following?
A.
PaO2, hemoglobin, mean arterial pressure B.
SaO2, hemoglobin, cardiac output C.
SvO2, cardiac index, SaO2
D.
PaO2, mean arterial pressure, SvO2
Answer: B. SaO2, hemoglobin, cardiac output
,Oxygen is delivered from the arterial end, so choose an option that has SaO2
4. Which of the following is the most significant complication of status asth- maticus?
A.
Pulmonary embolism
B.
Acute respiratory failure C.
Hypertension
D.
Anaphylaxis
Answer: B. Acute respiratory failure
5. A 22-year-old man is admitted to the critical care unit after a motor vehicle collision.
The emergency department nurse reports that he was unconscious at the scene of
the accident, but he is now alert and oriented. Skull films show a linear fracture of the
right temporal bone. He is at significant risk for
A.
scalp hematoma.
B.
, subdural hematoma. C.
epidural hematoma. D.
intracerebral hematoma.
Answer: C. epidural hematoma.
Linear fractures of the temporal bone frequently disrupt the middle meningeal artery and cause epidural hematoma.
Patients with an epidural hematoma classically present with a short period of unconsciousness followed by a lucid
interval and then rapid deterioration. An epidural hematoma is usually caused by arterial bleeding.
6. A patient is admitted to the ICU after sustaining a concussion and blunt
abdominal trauma to the right upper quadrant in a domestic dispute. The
patient's vital signs are BP 145/86 mm Hg, pulse 86 beats/min, respiration 15
breaths/min, and temperature 98.8° F. The nurse is monitoring the patient's bowel
sounds, abdominal tenderness, and abdominal girth frequently. Which of the following
laboratory parameters is especially important for the nurse to closely monitor for
bleeding in this patient?
A.
Platelet count
B.
Protime
