A 20-mm S wave in lead V1 and a 25-mm R wave in lead V6 are noted on a patient's
12-lead electrocardiogram. This would indicate which of the following?
A.
Right bundle branch block (RBBB)
B.
Left ventricular hypertrophy
C.
Posterior wall myocardial infarction (MI)
D.
Right ventricular hypertrophy - CORRECT ANSWER: B. Left ventricular hypertrophy
When the depth of the S wave in lead V1 or V2 plus the height of the R wave in lead V5
or V6 is 35 mm or greater, this constitutes voltage criteria for left ventricular
hypertrophy.
A 22-year-old man is admitted after a bicycle collision with a tree. He has a contusion on
the right side of his head. An intraventricular catheter has been inserted via a burr hole
to monitor his intracranial pressure (ICP). He develops respiratory depression and is
intubated and mechanically ventilated. Which of the following is the most likely cause of
an increase in ICP at this time?
A.
Positive pressure ventilation
B.
Hypocapnia caused by hyperventilation
C. Sedation D.
Cerebral dehydration caused by osmotic diuretics - CORRECT ANSWER: A. Positive
pressure ventilation
Positive pressure ventilation increases intrathoracic pressure, which leads to increased
ICP.
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
, lOMoAR cPSD| 65262174
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 22-year-old man is admitted with spontaneous pneumothorax. He is extremely
dyspneic and anxious. He also is complaining of tingling around his mouth and his
fingertips and feeling light-headed. Blood pressure is 120/82 mm Hg, heart rate is 110
beats/min, respiratory rate is 36 breaths/min and deep, and temperature is 37° C (98.6°
F). Which of the following would not be used to treat this condition?
A. Cal
cium
B. Che
st tube C.
Analgesia
D.
Calming the patient - CORRECT ANSWER: A. Calcium
Remember that respiratory alkalosis, caused by hyperventilation, increases the binding
between albumin and calcium and, therefore, reduces the serum ionized calcium level.
This is why the patient is having the symptoms of tetany. However, he does not need
calcium. He needs a reduction in minute ventilation, which will decrease his pH and
correct the binding between calcium and albumin, increasing the ionized calcium level.
Chest tube to re-expand the lung, analgesia to treat the chest discomfort, and calming
of the patient (including the use of sedatives) would be appropriate components of the
treatment plan for this patient.

A 24-year-old man has been diagnosed with acute kidney injury as a result of severe
hemorrhaging after a motor vehicle collision. Which of the following would be expected
laboratory values for this patient?
A.
Low urinary osmolality, high urinary sodium concentration
B.
High urinary osmolality, high urinary sodium concentration
C.
Low urinary osmolality, low urinary sodium concentration
D.
High urinary osmolality, low urinary sodium concentration - CORRECT ANSWER: D.
High urinary osmolality, low urinary sodium concentration
Consider that the kidney would want to conserve sodium and water with blood loss. If
the kidney is holding onto sodium, little is excreted into the urine, so urinary sodium is
low. If the kidney is holding onto water, little is excreted into the urine, so it is
concentrated and osmolality is increased.
A 24-year-old man is admitted to the critical care unit after sustaining a pulmonary
contusion in a motor vehicle collision. He has no history of cardiac or pulmonary
disease. During the first 24 hours after admission, he has been complaining of
increasing dyspnea, his respiratory rate has been increasing, and his oxygen saturation
via pulse oximetry has been decreasing despite supplemental oxygen. Breath sound
assessment reveals fine crackles bilaterally. Arterial blood gases reveal respiratory
alkalosis and hypoxemia. Chest x-ray film reveals patchy infiltrates. Acute respiratory
distress syndrome is diagnosed. Oxygen therapy is initiated, and arterial blood gases
are monitored closely, but SaO2 continues to fall. Which of these oxygen delivery
systems will provide the highest concentration of oxygen and indicated in this case?
A. Face
tent B.
Nonrebreathing mask
C.
Nasal cannula
D.
Venturi mask - CORRECT ANSWER: B. Nonrebreathing mask
The nonrebreathing mask stores oxygen in nose, pharynx, mask, and reservoir bag
between breaths. This allows a concentration of close to 100%.
