Your client, who weighs 143 lbs, had an 8-beat run of ventricular tachycardia. Lidocaine 1 mg/kg should be given immediately.

a. How many mg should be given?
b. How many mL of a 100 mg/10 mL syringe should be administered?

Use the formula: \[ \frac{D}{H} \times mL = \text{Dosage in mL} \]

Answer :

Final answer:

For a client who weighs 143lbs, around 65mg of Lidocaine should be administered which corresponds to 6.5ml in a 100mg/10ml syringe.

Explanation:

In the given scenario, your client who weighs 143lbs is required to be treated with Lidocaine at a dosage of 1mg/kg. To determine the dosage, convert the client's weight into kilograms (1 lb = 0.4536 kg), which results in a weight of 64.9kgs (143 lbs * 0.4536). Now, calculating the required dosage (1mg/kg * 64.9kgs), it comes out to be approximately 65mg.

Now, to find out how many milliliters are in a 100mg/10ml syringe to administer this dose, we can use the formula Dose Prescribed /Dose on hand * Quantity. So, it will be 65mg/100mg * 10ml = 6.5ml.
