A nurse is preparing to administer heparin 1,000 units/hr via continuous IVinfusion to a client. Available is heparin 25,000 units in 0.9% sodium chloride 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 ["10"]
IV pump rate (mL/hr) = (units/hr x volume) / total units
In this case, the units/hr is 1,000, the volume is 250 mL, and the total units is 25,000. IV pump rate (mL/hr) = (1,000 x 250) / 250,000
Therefore;
IV pump rate (mL/hr) = 250,000 / 25,000 IV pump rate (mL/hr) = 10
Therefore, the nurse should set the IV pump to deliver 10 mL/hr.

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.

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 ["1.8"]
Explanation
Dose = Desired dose / Available dose x Volume Therefore;
Dose = (56 mg / 160 mg) x 5 mL Therefore;
Dose = 0.35 x 5 mL Dose = 1.75 mL
Round to the nearest tenth: Dose = 1.8 mL
The nurse should administer 1.8 mL
