A nurse is preparing to administer lidocaine 7 mg/min via continuous IV infusion to a client who is pregnant and has a ventricular arrhythmia. Available is lidocaine 1 g in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["105"]
To calculate the IV pump setting, we need to convert the dosage from mg/min to mg/hr, and then find out how many mL/hr this corresponds to, given the concentration of the solution. First, multiply the ordered dose by 60 minutes to convert to an hourly rate: 7 mg/min * 60 min/hr = 420 mg/hr. Next, since we have 1 g of lidocaine in 250 mL, we convert 1 g to mg, which is 1000 mg. Now, we have 1000 mg in 250 mL, so we need to find out how many mL are needed for 420 mg. Using a proportion, we have 1000 mg/250 mL = 420 mg/x mL. Solving for x gives us x = (420 mg * 250 mL) / 1000 mg, which equals 105 mL. Therefore, the nurse should set the IV pump to deliver 105 mL/hr.

Correct Answer is A
Explanation
A. Giving the medication before meals helps to reduce gastric upset, which is a common side effect of nifedipine.
B. Contacting the provider to clarify the prescription is not necessary because the prescription specifies the frequency and route clearly.
C. Discontinuing the medication after three doses without further instruction from the provider could be premature and not in line with the treatment plan for premature contractions.
D. Administering nifedipine sublingually is not the appropriate route for this medication; it is typically administered orally.
