DHA Accident and Emergency/ Emergency Room - Additional Info Sample Questions

After doing successful CPR on a patient that was admitted to the ER in pulseless ventricular tachycardia, the physician ordered Lidocaine to be administered to help prevent the patient from going into ventricular tachycardia again. You are ordered to give this patient a bolus and then hang a Lidocaine drip before they are transported to the intensive care unit. With which type of patient would you not decrease the amount of Lidocaine to half of what is typically given?

Correct Answer:
a 45 year old electrician that was electrocuted.


lidocaine is a medication commonly used in medical settings to manage and prevent ventricular arrhythmias, such as ventricular tachycardia. after a patient experiences a cardiac event where ventricular tachycardia is involved, it is crucial to stabilize the heart's rhythm to prevent further complications. administering lidocaine can be an effective way to achieve this. however, the dosage of lidocaine must be carefully considered based on the patient's overall health condition, particularly focusing on liver and kidney function as well as age.

in the case of a 45-year-old electrician who was electrocuted and successfully resuscitated, it is likely that the patient has no pre-existing liver or kidney disease unless otherwise noted. patients with healthy liver and kidney functions can metabolize and excrete lidocaine effectively, allowing them to tolerate standard dosages of the drug. therefore, for such a patient, the full dose of lidocaine can be administered safely.

contrastingly, certain patients require adjustments to the lidocaine dosage. patients suffering from liver disease, such as a 50-year-old awaiting a liver transplant, have impaired ability to metabolize drugs. since lidocaine is metabolized primarily in the liver, these patients are at higher risk of toxicity if given the full dose. similarly, patients with kidney disease, such as those on peritoneal dialysis, may have altered drug clearance that can lead to accumulation of lidocaine, necessitating dosage adjustments.

elderly patients, like the 90-year-old lady who experienced a cardiac arrest at the grocery store, also often require reduced doses of lidocaine. aging can affect both liver and kidney functions, reducing the body's ability to process and eliminate drugs efficiently. this demographic is more susceptible to adverse effects and toxicity if given drugs at standard dosages intended for younger, healthier adults.

hence, in the context of administering lidocaine post-cardiac arrest due to ventricular tachycardia, a patient like the 45-year-old electrician, presumed to have intact liver and kidney function, would not require a reduction in the lidocaine dosage. conversely, careful consideration and potential dosage adjustments are necessary for patients with known liver or kidney impairments and for elderly patients to avoid complications related to drug toxicity.
