failure [LVF]?

A patient has had a triple-lumen subclavian catheter through which he has been
receiving total parenteral nutrition, maintenance fluids, and antibiotics via the catheter.
He has been slightly confused. Suddenly he grasps the catheter and pulls it out. Shortly
thereafter, he complains of shortness of breath and his pulse oximetry indicates an
SpO2 of 84%. In the management of this patient, he should 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
Visualize a large air bubble in the patient's heart. Think: what position would hinder an
air embolism from leaving 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 - Answer B. SaO2, hemoglobin, cardiac output
Since oxygen is delivered from the arterial end, therefore choose an option which has
SaO2

A 22-year-old male is admitted to the critical care unit following a motor vehicle
collision. The ED nurse describes that he was found unconscious at the scene of the
accident but now appears alert and oriented. Skull films reveal a linear fracture of the
right temporal bone. Based on his description, this patient is in significant risk for:
A.
Scalp hematoma.
,B.
Subdural hematoma.
C.
Epidural hematoma.
D.
Intracerebral hematoma. Answer C. epidural hematoma.
Linear temporal bone fractures generally consist of laceration of middle meningeal
artery, with resultant epidural hematoma. Classically, a patient has brief
unconsciousness, then usually a lucid period followed by rapid deterioration in the state
of consciousness with an epidural hematoma. Typically an epidural hematoma is caused
by bleeding from an artery.
A patient is admitted to the ICU with a concussion and blunt abdominal trauma to the
right upper quadrant after being involved in a domestic dispute. BP 145/86 mm Hg Pulse
86 beats/min Respiration 15 breaths/min 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 specifically important for the nurse to
closely monitor this client for bleeding?
A.
Platelet count
B.
Protime
C.
Hematocrit
D.
Mean corpuscular volume - Answer C. Hematocrit
The most frequent injuries from blunt abdominal trauma are injury to the liver, spleen,
mesenteric vessels, pancreas, or kidneys. In a nonoperative management of blunt
, abdominal trauma, observation and monitoring include serial hematocrits to assess for
intra-abdominal bleeding. The platelet count does not fluctuate unless there is a disease
process, such as cirrhosis or leukemia, or significant blood loss. Protime is a monitor of
coagulation status and can be prolonged without active bleeding. Mean corpuscular
volume measures the average volume or size of a single RBC and is used in classifying
anemias.
Which of the following is associated with chest pain, confusion, and petechiae?
A.
Dissecting aneurysm
B.
Fat embolism
C.
Pneumothorax
D.
Myocardial infarction - Answer B. Fat embolism
Chest pain, confusion, and petechiae are indicative of a fat embolism, particularly within
the initial 48 to 72 hours after the onset of a long-bone fracture.
The clincher is the petechiae. None of the other choices would cause petechiae.
Which of the following is most likely iatrogenic in origin?
A.
Hypovolemic
B.
Cardiogenic
