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?

Oxygen delivery (DO2) is the product of which of the following?
t t t t t t t t t t

PaO2, hemoglobin, mean arterial pressure
t t t t

SaO2, hemoglobin, cardiac output

t D.
PaO2, mean arterial pressure, SvO2 - ANSWER: ➡ B. SaO2, hemoglobin, cardiac output

A 22-year-old man is admitted to the critical care unit after a motor vehicle collision. The
t t t t t t t t t t t t t t t
emergency department nurse reports that he was unconscious at the scene of the accident, but
t t t t t t t t t t t t t t t
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. t
t B.
subdural hematoma. t
t C.
epidural hematoma. t
t D.
intracerebral hematoma. - ANSWER: ➡ C. epidural hematoma. t t t tt t t t
Linear fractures of the temporal bone frequently disrupt the middle meningeal artery and
t t t t t t t t t t t t
cause epidural hematoma. Patients with an epidural hematoma classically present with a short
t t t t t t t t t t t t t
period of unconsciousness followed by a lucid interval and then rapid deterioration. An
t t t t t t t t t t t t t
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
t t t t t t t t t t t t t t t t
right upper quadrant in a domestic dispute. The patient's vital signs are BP 145/86 mm Hg,
t t t t t t t t t t t t t t t t
pulse 86 beats/min, respiration 15 breaths/min, and temperature 98.8° F. The nurse is
t t t t t t t t t t t t t
monitoring the patient's bowel sounds, abdominal tenderness, and abdominal girth
t t t t t t t t t t
frequently. Which of the following laboratory parameters is especially important for the nurse
t t t t t t t t t t t t t
to closely monitor for bleeding in this patient?
t t t t t t t t
A.
Platelet count t
t B.
Protime
t C.
Hematocrit
t D.
Mean corpuscular volume - ANSWER: ➡ C. Hematocrit
t t t t tt t t
Common injuries resulting from blunt abdominal trauma can include injury to the liver, spleen,
t t t t t t t t t t t t t
mesenteric vessels, pancreas, or kidneys. In a nonoperative approach to blunt abdominal
t t t t t t t t t t t t
, trauma, observation and monitoring include serial hematocrits to evaluate for intra-
t t t t t t t t t t t
abdominal bleeding. The platelet count does not fluctuate unless there is a disease process (e.g.
t t t t t t t t t t t t t t
cirrhosis, leukemia) or significant blood loss. Protime is a monitor of coagulation status and can
t t t t t t t t t t t t t t t
be prolonged without active bleeding. Mean corpuscular volume measures the average volume
t t t t t t t t t t t t
or size of a single RBC and is used in classifying anemias.
