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."
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."
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
Which of the following is the most significant complication of status
asthmaticus?
A.
Pulmonary embolism
B.
Acute respiratory failure
C.
,Hypertension
D.
Anaphylaxis - ANSWER-B. Acute respiratory failure
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.
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 - ANSWER-C. Hematocrit
Common injuries resulting from blunt abdominal trauma can include
injury to the liver, spleen, mesenteric vessels, pancreas, or kidneys.
In a nonoperative approach to blunt abdominal trauma, observation
and monitoring include serial hematocrits to evaluate for
intraabdominal bleeding. The platelet count does not fluctuate unless
there is a disease process (e.g. cirrhosis, leukemia) or significant
blood loss. Protime is a monitor of coagulation status and can be
prolonged without active bleeding. Mean corpuscular volume
