Chapter 26 (EMT)

Platelets are actually fragments of larger cells that are crucial to the formation of clots. Clumping (called aggregation) of platelets is the body's most rapid response to stop bleeding from an injured site. However, in some situations the clumping of platelets is not desirable, such as when a plaque in a coronary artery ruptures. In this situation, the rapid clumping of platelets can cause a clot that then completely blocks the coronary artery and results in a heart attack (myocardial infarction). One of the most effective and widely available drugs to prevent the aggregation of platelets is: Aspirin. Plasma. Hemoglobin. Anemia.

Aspirin.

Why might you consider contacting medical direction before applying a tourniquet in the case of uncontrollable bleeding from an AV fistula? Damage to the fistula may occur. The patient may be in danger of losing the limb. Medical direction should be contacted before any use of tourniquets. Hemodialysis anticoagulants may make bleeding more severe.

Damage to the fistula may occur.

The correct terminology used for patients whose kidneys are damaged to the point where they require dialysis to survive is: Acute renal failure. End-stage renal disease. Hepatic failure. Terminal kidney disease.

You are dispatched to an unconscious hemodialysis patient. On arrival to the dialysis clinic, the patient is unresponsive, apneic, and pulseless. You secure the ABCs, begin ventilation, and initiate chest compressions. However, the patient's cardiac arrest rhythm is continuously unresponsive to defibrillations with your AED. The best approach is to: All online medical control to terminate the code. The probability of survival is too low to continue resuscitation efforts. Begin transporting and contact an ALS intercept. The patient's dysrhythmia may be related to kidney failure. Run a "no-electricity" code in which compressions and ventilation are continued. No additional defibrillations are necessary. Continue defibrillating as the monitor recommends. The myocardium becomes increasingly responsive to successive defibrillations.
