Question 1

Esmolol (Brevibloc) is metabolized by which mechanism?

Accepted Answer

Plasma hydrolysis

Answer

Explanation:
Esmolol is the only beta-adrenergic receptor antagonist cleared through plasma hydrolysis.

Question 2

Which medication produces dissociative anesthesia?

Accepted Answer

Ketamine (Ketalar)

Answer

Explanation:
Ketamine is an NMDA-receptor-blocking medication that produces a functional dissociation between the thalamocortical and limbic systems, a state that has been termed dissociative anesthesia. It produces dose-dependent CNS depression characterized by profound analgesia and amnesia by depressing neuronal function in the cerebral cortex and thalamus, while simultaneously activating the limbic system.

Question 3

Which medication should be administered to a patient who is unresponsive and hypoxic after receiving midazolam (Versed) for a 20-minute gastrointestinal procedure?

Accepted Answer

Flumazenil (Romazicon)

Answer

Explanation:
A benzodiazepine antagonist such as flumazenil can be used to reverse the sedative effects of benzodiazepines such as midazolam. It can be used for excessive sedation but should not be used routinely.

Question 4

The P wave on an ECG tracing corresponds with:

Accepted Answer

atrial depolarization.

Answer

Explanation:
Atrial depolarization corresponds with the P wave on ECG tracing.

Question 5

Which drug would carry the HIGHEST risk of an adverse drug reaction with IV contrast dye during a lower limb angiography?

Accepted Answer

Metformin (Glucophage)

Answer

Explanation:
Of the drugs listed, the only medication that carries an adverse drug reaction risk with contrast dye is metformin. When given in conjunction with contrast dye, it is associated with an increased potential for lactic acidosis. The combination of the 2 drugs could expose the patient to significant contrast-induced nephropathy.
