H And T

Question 0

Hypoxia

Answer 0

Slow rate, cyanosis, airway problems, blood gasses, give oxygen/ventilation/ advance airway

Question 1

Hypovolemia

Answer 1

Rapid heart rate, folate neck veins, give volume infusions

Question 2

Hydrogen ion

Answer 2

Smaller amplitude QRS complexes, history of diabetes/renal failure/bicarbonate-responsive pre existing acidosis, give ventilation sodium bicarbonate

Question 3

Hyper kalmia

Answer 3

High potassium, QRS widen, tall T waves, small P waves, history of renal failure/recent dialysis/diabetes/medications, give calcium chloride, sodium bicarbonate, glucose plus insulin, possibly albuterol

Question 4

Hypokalemia

Answer 4

Low potassium, T waves flat, prominent U waves, wide complex tachy, abnormal loss of potassium, give magnesium if cardiac arrest

Question 5

Hypothermia

Answer 5

J or Osborne waves, history of exposure to cold, rewarm according to protocol

Question 6

Tension pneumothorax

Answer 6

Narrow complex, slow heart rate, no pulse felt with CPR, unequal breath sounds, difficult to ventilate patient, give needle decompression, tube thoracostomy

Question 7

Tamponade, cardiac

Answer 7

Narrow complex, rapid rate, no pulse felt with CPR, vein distention, give pericardiocentesis

Question 8

Toxins

Answer 8

Various effects of ECG, predominately prolongation of QT interval, bradycardia, pupils, neurological exam, give intubation, specific antidotes and agents per toxidrome

Question 9

Thrombosis, lung

Answer 9

Narrow complex, rapid rate, no pulse felt with CPR, distended neck veins, give fibrinolytic therapy, surgical embolectomy

Question 10

Thrombosis, heart

Answer 10

Abnormal 12-lead ECG, history of cardiac markers, good pulse with CPR
