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 - Correct 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 - Correct 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 Correct 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 -Correct 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. -Correct 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 - Correct 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 intra-abdominal 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 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 - Correct Answer✔✔ B. Fat embolism
Chest pain, confusion, and petechiae are suggestive of a fat
embolism, especially within the first 48 to 72 hours after a long-
bone fracture.
The clincher is the petechiae. None of the other choices would
cause petechiae.
Which type of shock is most likely to be iatrogenic?
A.
Hypovolemic
B.
Cardiogenic
C.
Septic
D.
Neurogenic - Correct Answer✔✔ C. Septic
Which of the following is true?
A. The diastolic pulmonary artery pressure (PAd) should not be
higher than the pulmonary artery occlusive pressure (PAOP).
