The response to catecholamines in an injured, hypovolemic pregnant woman can
be expected to result in:
a. Placental abruption
b. Fetal hypoxia and distress
c. Fetal/maternal dysrhythmia
d. Improved uterine blood flow
e. Increased maternal renal blood flow
✔️ Correct Answer: B
Rationale: In a hypovolemic pregnant patient, catecholamine release causes
vasoconstriction in non-vital organs, including the uterus. This reduces uterine
blood flow, leading to fetal hypoxia and distress. Placental abruption (Option A) is
a separate condition. Dysrhythmias (Option C) are not the primary response.
Uterine blood flow (Option D) decreases, not improves. Renal blood flow (Option
E) also decreases.
,During an altercation, a 36-year-old man sustains a gunshot wound above the
nipple line on the right, with an exit wound posteriorly above the scapula on the
right. He is transported by ambulance to a community hospital. He is
endotracheally intubated, chest tube thoracostomy is performed, and 2 liters of
Ringer's lactate solution are infused via 2 large-caliber IVs. His blood pressure
now is 60/0 mmHg, heart rate is 160 beats per minute, and respiratory rate is 14
breaths per minute (ventilated with 100% O2). The most appropriate next step in
managing this patient is:
a. Laparotomy
b. Diagnostic peritoneal lavage
c. Arterial blood gas determination
d. Administer packed red blood cells
e. Chest X-ray to confirm tube placement
✔️ Correct Answer: D
Rationale: The patient remains hypotensive despite adequate fluid resuscitation,
indicating ongoing hemorrhage. The priority is to administer blood products to
restore circulating volume. Diagnostic peritoneal lavage (Option B) and ABG
determination (Option C) are not the priority. Laparotomy (Option A) may be
needed but blood administration is the immediate next step. Chest X-ray (Option
E) is secondary.
An electrician is electrocuted by a downed power line after a thunderstorm. He
apparently made contact with the wire at the level of the right mid thigh. In the
ED, his vital signs are normal and no dysrhythmia is noted on ECG. On
examination, there is an exit wound on the bottom of the right foot. His urine is
,positive for blood by dipstick but no RBCs are seen microscopically. Initial
management should include:
a. Immediate angiography
b. Aggressive fluid infusion
c. Intravenous pyelography
d. Debridement of necrotic muscle
e. Admission to the ICU for observation
✔️ Correct Answer: B
Rationale: The presence of dipstick-positive urine without RBCs indicates
myoglobinuria from rhabdomyolysis following electrical injury. Aggressive fluid
infusion is essential to prevent acute kidney injury. Angiography (Option A), IV
pyelography (Option C), and debridement (Option D) are not initial priorities.
Admission for observation (Option E) is insufficient without aggressive hydration.
A 23-year-old construction worker is brought to the ED after falling more than 9
meters from scaffolding. He is complaining bitterly of lower abdominal and lower
limb pain, and has obvious deformity of both lower legs with bilateral open tibial
fractures. Which one of the following statements concerning this patient is true?
a. Pelvic injury can be ruled out based on the mechanism of injury
b. Blood loss from the lower limb is most likely cause of his hypotension
c. Spinal cord injury is the most likely cause of his hypotension
d. X-ray of the chest and pelvis are important adjuncts in his assessment
e. Aortic injury is the most likely cause of his tachycardia
✔️ Correct Answer: D
Rationale: In a high-velocity fall, chest and pelvic X-rays are essential to identify
life-threatening injuries. Pelvic injury (Option A) cannot be ruled out. Lower limb
, blood loss (Option B) is unlikely to cause significant hypotension alone. Spinal
cord injury (Option C) is not the most likely cause of hypotension. Aortic injury
(Option E) is less common than pelvic injury in this mechanism.
Early central venous pressure monitoring during fluid resuscitation in the ED has
the greatest utility in a:
a. Patient with a splenic laceration
b. Patient with an inhalation injury
c. 6-year-old child with a pelvic fracture
d. Patient with a severe cardiac contusion
e. 24-year-old man with a massive hemothorax
✔️ Correct Answer: D
Rationale: CVP monitoring is most useful in patients with cardiac contusion
where fluid management must be carefully balanced to avoid volume overload.
Splenic laceration (Option A) typically requires operative intervention. Inhalation
injury (Option B) requires respiratory management. Pediatric pelvic fracture
(Option C) may be managed with fluid boluses. Hemothorax (Option E) requires
chest tube placement.
A young man sustains a rifle wound to the mid-abdomen. He is brought promptly
to the ED by prehospital personnel. His skin is cool and diaphoretic, and his
systolic blood pressure is 58 mmHg. Warmed crystalloid fluids are initiated
without improvement in his vital signs. The next, most appropriate, step is to
perform:
