Question 1

Most common cause of ATN i normotesnive patient with crush injuries

Accepted Answer

Rhabdomyolusis- acute muscle destruction associated with myoglobinuria

Question 2

Ripping and radiating chest pain. Asymetric blood pressures. Other vss. Diastolic Murmor at second R inctercostal space then blood pressure drops and the patient is restless and thrashing in bed.

Accepted Answer

Dissecting thoracic Aortic Aneurysm.

Question 3

A 32-year-old woman has systemic lupus erythematosus and chronic kidney disease. Over the past 2 weeks, she has complained of feeling fatigued and short of breath after minimal exertion. She is receiving hemodialysis. Her hemoglobin level is 4.5 g/dl.Which of the following is indicated?

Accepted Answer

Recombinant human erythropoietin (Epogen)

Question 4

Which of the following is the most common cause of death associated with an acute myocardial infarction?

Accepted Answer

Cardiac dysrhythmias (especially ventricular) are the leading cause of death in myocardial infarctions primarily because patients do not go to the emergency department in a timely manner. Though the mortality of cardiogenic shock is high, it does not occur as often as ventricular dysrhythmias.

Question 5

endocarditis

Accepted Answer

With a history of intravenous drug abuse or pulmonary artery catheter, the tricuspid valve is most likely affected. Vegetation from the tricuspid valve would go to the pulmonary arterial system and cause symptoms of pulmonary emboli and possibly pulmonary infarction.

Question 6

pathophysiologic effect of acute respiratory distress syndrome (ARDS) on the lung?

Accepted Answer

Patients with ARDS usually have high peak inspiratory pressures indicative of decreased pulmonary compliance. Choose "Decreased pulmonary compliance."
Lungs become stiff as a result of alveolar collapse and surfactant deficiency. This decreased compliance (expandability) causes an increase in the work of breathing and patient fatigue. Pulmonary vascular resistance is increased, functional residual capacity is decreased, and alveolar surface tension is increased.

Question 7

Diffuse ST segment elevation is associated with

Accepted Answer

Pericarditis

Question 8

Posterior MI leads

Accepted Answer

anterior St depression in leads

Question 9

Wet to dry not healing because...

Accepted Answer

Wet to dry dressing changes remove healthy granulating tissue required for wound healing.

Question 10

common to all forms of shock?

Accepted Answer

Decrease in cellular oxygenation

Question 11

intra-abdominal pressure monitoring?

Accepted Answer

Decompression laparotomy should be considered when the pressure exceeds 20 mm Hg.
The transducer should be leveled to the symphysis pubis
The bladder pressure closely reflects intraperitoneal pressure.
Physiologic compromise begins at a pressure of 12 to 15 mm Hg.

Question 12

Which of the following would you expect to see in a patient with serum potassium of 7 mEq/L?

Accepted Answer

Flaccid paralysis and diarrhea
