Free DAANCE Anesthesia Techniques Questions and Answers 1

Question 1

Which signs are associated with malignant hyperthermia during anesthesia?

Accepted Answer

Tachycardia, CO2 retention, muscle rigidity, increase in body temperature

Answer

Malignant hyperthermia is a severe hypermetabolic state characterized by an uncontrolled release of calcium in skeletal muscle. Key signs include a rapid increase in heart rate (tachycardia), excessive carbon dioxide production (CO2 retention), generalized muscle rigidity, and a dangerously rapid rise in body temperature. These symptoms indicate a life-threatening metabolic crisis.

Question 2

Which interventions are recommended for treating malignant hyperthermia during anesthesia?

Accepted Answer

EMS activation, oxygen therapy, dantrolene administration, cold saline IV, application of ice packs to groin, axilla, and neck

Answer

Immediate treatment for malignant hyperthermia involves discontinuing the triggering agent and administering dantrolene, a muscle relaxant that inhibits calcium release. Aggressive cooling measures, such as cold saline IV and external ice packs to the groin, axilla, and neck, are crucial to lower body temperature. Additionally, 100% oxygen therapy is vital to address the increased metabolic demand, and EMS should be activated.

Question 3

Which part of the eye loses reflex on induction of anesthesia?

Accepted Answer

Eyelid

Answer

During the induction of general anesthesia, the eyelid reflex is one of the first protective reflexes to disappear. The absence of this reflex, which involves involuntary blinking or resistance to eye opening, indicates that the patient has reached a sufficient depth of anesthesia for procedures like intubation or surgery to commence safely.

Question 4

What is the advantage of using local anesthetic alone?

Accepted Answer

Patient does not need to be NPO (nothing by mouth) and no driver is necessary

Answer

A significant advantage of using local anesthetic alone is that it does not typically impair consciousness or motor function to the extent that systemic sedation or general anesthesia does. Consequently, patients are generally not required to be NPO (nothing by mouth) before the procedure and can often drive themselves home afterward, offering greater convenience and fewer logistical hurdles.

Question 5

What is balanced anesthesia?

Accepted Answer

All of the above

Answer

Balanced anesthesia is a technique that combines multiple anesthetic agents to achieve all desired components of anesthesia. These components include amnesia (loss of memory), analgesia (pain relief), muscle relaxation/immobility, and loss of consciousness. This approach allows for lower doses of individual drugs, minimizing side effects while ensuring a safe and effective surgical state.
