A client is prescribed diazepam (Valium) 5 mg IVP over 2 minutes. The medication available is 5 mg/mL. How many mL of the medication will the nurse provide every 30 seconds?
1. 0.25 mL
2. 0.50 mL
3. 0.75 mL
4. 1.00 mL
1
Rationale 1: Begin with using the equation of 1 mL/120 seconds and divide both the numerator and denominator by 2 or 0.5 mL/60 seconds. To determine the volume to administer every 30 seconds divide the fraction 0.5 m/60 seconds by 2 again, or 0.25 mL/30 seconds. The nurse will provide 0.25 mL of the medication every 30 seconds.
