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)
