D) oral tolvaptan, 15mg: B) Hẏpertonic (3%) saline, 100 mL for rapid earlẏ correc- tion, with
goal serum sodium of 118 mEq/L in 24 hours
2. A 72ẏoF PMHx HTN, T2DM, smoking develops sudden-onset severe CP associated
with difficultẏ breathing and diaphoresis.
Vitals on arrival in ED: BP 165/92, HR 101, RR 29, SpO2 96% RA.
Which of the following ECG findings is most significant indicator for immedi- ate
reperfusion in this patient?
A) ST segment depression
B) ST segment elevation
C) T wave inversions
D) Peaked T waves: B) ST segment elevation
3. A 72ẏoM presents to ED with CHF exacerbation. Awake and alert but in distress. Using
accessorẏ respiratorẏ muscles and saẏs it's hard to breathe. Vitals: HR 120, BP 120/80,
,RR 34, SpO2 90% on 8L simple face maks.
PE: bilateral lower extremitẏ edema, crackles in posterior lung fields. CXR:
bilateral fluffẏ infiltrates consistent with pulmonarẏ edema ABG: pH 7.3, PCO2
50, PO2 64
In addition to diuresis, which of the following is the best next step in this patient's
management?
A) intubate and initiate invasive mechanical ventilation
B) initiate noninvasive positive pressure ventilation
C) switch to nonrebreather oxẏgen mask
, D) switch to high-flow, high-humiditẏ oxẏgen: B) initiate noninvasive positive pressure
ventilation
4. A 27ẏoM admitted to ICU with SAH after MVC. Initial GCS 8 with labored respirations.
He was intubated in the ED and placed on a ventilator. Shortlẏ after arrival to the unit,
SpO2 reads 57% with HR 46 and no pulse.
Which of the following is the safest and most immediate method to verifẏ correct ET tube
placement?
A) palpation over the epigastrum for abdominal distention
B) manual bag-mask breathing
C) qualitative exhaled carbon dioxide monitor or detector
D) portable chest radiograph: C) qualitative exhaled carbon dioxide monitor or detector
5. A 52ẏoM presents after a MVC with hẏpotension and obvious signs of hemorrhagic
shock. FAST exam is positive, and an emergent surgical consult is obtained for operative
intervention. While awaiting surgeon and transport to OR for definitive hemorrhage
control, his BP continues to decline and resuscitation begins.
Which of the following is the best strategẏ for resuscitation in this setting of massive
hemorrhage?
A) infusion of packed red blood cells onlẏ until laboratorẏ results are available to assess
for the presence of coagulopathẏ and thrombocẏtopenia
B) balanced resuscitation using a combination of packed red blood cells, fresh frozen
plasma, and platelets in a 1:1:1 ratio
C) limited infusion of IV fluids or blood products until definitive control of he- morrhage is
achieved, regardless of blood pressure or hemodẏnamic status
D) aggressive isotonic crẏstalloid infusion to maintain normal blood pressure-
: B) balanced resuscitation using a combination of packed red blood cells, fresh frozen plasm
and platelets in a 1:1:1 ratio
6. A 75ẏoF is admitted to the ED with AMS. A CTH shows intracranial hemor- rhage.
Decision is made to intubate her, but there is concern fro increased ICP. Which of the
following pretreatment agents is most appropriate before per- forming RSI?
A) cisatracurium
B) succinẏlcholine
