FPC/ CFRN- Review Exam Version B Questions With Complete Solutions. Myxedema coma is also known as... A. Thyroid storm B. Adrenal insufficiency C. Hypothyroidism D. Hyperaldosteronism - 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 - 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 FPC/ CFRN- Review Exam Version B Questions With Complete Solutions B. Right ventricular infarction C. CHF D. Sepsis - 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 - 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 - 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 - 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 - 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 - 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 - 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 - 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 - ANSWER Ketamine (ketalar) Ativan: indication dose, max - ANSWER Lorazepam, seizures, 1-2 mg, max 4 mg Mannitol dose - ANSWER 1-2 g/kg Mannitol: an osmotic diuretic, acts by osmosis to ensure urine production and may prevent heme deposition in the kidney. Can be administered to avoid acute renal failure when fluid administration has been ineffective. Drug choice for cyclic antidepressant OD - ANSWER Sodium bicarbonate .
