A nurse is reviewing a new prescription for propranolol 200 mg PO daily divided in equal doses every 12 hr for a client who has migraine headaches during the premenstrual period. Available is propranolol solution 4 mg/mL. How many mL should the client self-administer per dose?
(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 ["25"]
mL = mg / 4 mL = 100 / 4
mL = 25 / 1
This means that the client needs to take 25 mL of the propranolol solution every 12 hours to get the prescribed dose of 200 mg per day

Correct Answer is A
Explanation
Bisacodyl is a stimulant laxative that works by increasing the activity of the intestines to cause a bowel movement. It is usually used on a short-term basis to treat constipation or to empty the bowels before surgery or certain medical procedures. However, bisacodyl should not be used in postpartum clients who have had a cesarean delivery or an episiotomy, as it may cause straining and increase the risk of bleeding or infection. Therefore, the nurse should clarify this prescription with the provider and suggest an alternative laxative that is safer for postpartum clients, such as docusate sodium or psyllium.
Calcium carbonate 750 mg PO.
There is no need to clarify this prescription. Calcium carbonate is a common supplement used to provide calcium to the body, and it is typically taken orally.
Oxycodone 5 mg PO every 4 hr PRN for severe pain.

Ibuprofen 600 mg PO every 6 hr PRN for moderate pain.
There is no need to clarify this prescription. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief, including moderate pain. The specified dose and frequency are within the usual range.
Correct Answer is ["45"]
Explanation
Infusion rate in mL/h = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL) In this case, the dose is 2 mcg/kg/min and the concentration is 50 mg/250 mL or 200 mcg/mL. Therefore, the infusion rate is:
Infusion rate (mL/h) = 2 x 75 x 60 / 200 Infusion rate (mL/h) = 45
The nurse should set the IV pump to deliver 45 mL/h.
