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 -ANS✔✔--A. Head down, left side
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 -ANS✔✔--B. S3
LVF would be the most subtle because early changes are usually subtle
changes. Choose "S3."
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."
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 -ANS✔✔--B. SaO2, hemoglobin,
cardiac output
Oxygen is delivered from the arterial end, so choose an option that has SaO2
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. -ANS✔✔--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.
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
C.
Hematocrit
D.
Mean corpuscular volume -ANS✔✔--C. Hematocrit
Which of the following is the most significant complication of status asthmaticus?
