An older adult client with a gastric ulcer receives a prescription for omeprazole 40 mg PO daily. The medication is available in 20-mg delayed-release capsules. How many capsule(s) should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["2"]
Calculation:
Prescribed dose = 40 mg
Available dose per capsule = 20 mg/capsule
Calculate the number of capsules to administer:
Number of capsules = Prescribed dose / Available dose per capsule
= 40 mg / 20 mg/capsule
= 2 capsules

Correct Answer is ["400"]
Explanation
Calculation:
Total cefazolin in the vial = 1 gram
Convert the total amount of cefazolin from grams to milligrams:
Total cefazolin (mg) = Total cefazolin (grams) x 1000 mg/gram
= 1 gram x 1000 mg/gram
= 1000 mg
Identify the total volume after reconstitution: 2.5 mL
Calculate the concentration of cefazolin in mg/mL:
Concentration (mg/mL) = Total cefazolin (mg) / Total volume (mL)
= 1000 mg / 2.5 mL
= 400 mg/mL
Correct Answer is ["6"]
Explanation
Calculation:
Determine the concentration of oxytocin in the IV solution in milliunits/mL:
Total units of oxytocin = 20 units
Convert units to milliunits:
20 units x 1000 milliunits/unit = 20000 milliunits
Total volume of solution = 1 liter = 1000 mL
Concentration = Total milliunits / Total volume
= 20000 milliunits / 1000 mL
= 20 milliunits/mL
Calculate the desired dose per hour in milliunits:
Desired dose per minute = 2 milliunits/min
Desired dose per hour = 2 milliunits/min x 60 minutes/hour
= 120 milliunits/hour
Calculate the infusion rate in mL/hour:
Infusion rate (mL/hour) = Desired dose per hour (milliunits/hour) / Concentration (milliunits/mL)
= 120 milliunits/hour / 20 milliunits/mL
= 6 mL/hour
