Exam QUESTIONS AND CORRECT
ANSWERS
Myxedema coma is also known as...
A. Thyroid storm
B. Adrenal insufficiency
C. Hypothyroidism
D. Hyperaldosteronism - CORRECT ANSWER Hypothyroidism
Most common presentation of a patient with hypothyroidism are all of the following,
Except...
A. Cold intolerance with coarse hair
B. Almost exclusively over the age of sixty
C. >90% of cases occur in the winter
D. Primarily in men - CORRECT ANSWER Primarily in men
Hypothroidism occurs primarily in women, almost exclusively over the age of sixty, with
90% of the cases occurring in the winter months.
Your patient presents with following parameters: CVP 0, CI 1, PA S/D 8/4, wedge 3, and
SVR 1,800. What is your diagnosis?
A. Hypovolemic shock
B. Right ventricular infarction
C. CHF
D. Sepsis - CORRECT ANSWER Hypovolemic shock
,Careful interpretation of the CVP is important!
Central venous pressure (CVP) describes the pressure of blood in the thoracic vena cava, near
the right atrium of the heart.
CVP reflects the amount of blood returning to the heart and the ability of the heart to pump
the blood into the arterial system.
Drug of choice for profound hypotension in septic shock is?
A. Isotonic crystalloid solution
B. Levophed
C. Nipride
D. Dobutamine - CORRECT ANSWER Levophed
Sepsis is by far the most common cause of distributive shock.
The average normal ICP range is...
A. 0-10 mmHg
B. 10-20 mmHg
C. 20-30 mmHg
D. >30 mmHg - CORRECT ANSWER Normal ICP range is 0-10 mmHg, but range
can go as high as 15 mmHg.
The formula to calculate MAP is
A. 2/3 DBP × SBP
B. 2 × DBP + SBP divided by 3
,C. 2 × SBP + DBP
D. 2 + DBP × SBP divided by 3 - CORRECT ANSWER 2 × DBP + SBP / 3
(normal 80-100 mmHg)
Normal coronary perfusion pressure (CPP) is
A. 50-60 mmHg
B. 70-90 mmHg
C. 80-100 mmHg
D. <50 mmHg - CORRECT ANSWER Normal 50-60 mmHg
Coronary perfusion pressure: (CPP) = DBP-PAWP
The patient presents with the following hemodynamic parameters: CVP 1, CI 1.7, PA S/D
12/6, wedge 6, and SVR 300. Vital signs are 78/40, HR 60, RR 16, SaO2 98%. The most
likely cause is...
A. RVMI
B. Neurogenic shock
C. Septic shock
D. Hypovolemic shock - CORRECT ANSWER Neurogenic shock
SVR < 800, think distributive shock. Next look at the CI; is it less than 2.5? Hypotension and
either a normal heart and/or bradycardia present narrows the type of distributive shock as
being neurogenic shock.
Severe hypothermic Pt's are at highest risk for which of the following rhythm?
A. A-Fib
, B. Asystole
C. V-Fib
D. Sinus Brady - CORRECT ANSWER V-Fib
Severe: 20-28 (coma, VF common)
The drug of choice for a patient exhibiting signs and symptoms of malignant hyperthermia is:
A. Anectine
B. Sodium bicarbonate
C. Dantrolene
D. Glucagon - CORRECT ANSWER Dantrolene
Malignant hyperthermia: Characteristic signs are muscular rigidity, followed by a
hypercatabolic state; with increased oxygen consumption, increased carbon dioxide
production (hypercapnea, usually measured by capnography), tachycardia (fast heart rate),
and an increase in body temperature (hyperthermia) at a rate of up to ~2°C per hour,
temperatures up to 42°C (108°F) are not uncommon.
Induction agent of choice with bronchospastic patients - CORRECT
ANSWER Ketamine (ketalar)
Ativan: indication dose, max - CORRECT ANSWER Lorazepam, seizures, 1-2 mg,
max 4 mg
Mannitol dose - CORRECT ANSWER 1-2 g/kg
Mannitol: an osmotic diuretic, acts by osmosis to ensure urine production and may prevent
heme deposition in the kidney.
