A client is to be started on a heparin intravenous infusion at 2,000 units per hour. On hand is an IV bag labeled 25,000 units/ 250 mL. At what rate (mL/hour) will the nurse set the pump? (Answer to the nearest whole number)
The Correct Answer is ["20"]
Identify the total units of heparin in the bag:
The IV bag contains 25,000 units of heparin in 250 mL.
Identify the desired hourly dose:
The client is ordered to receive 2,000 units of heparin per hour.
Calculate the mL containing 2,000 units:
We can set up a proportion:
(25,000 units) / (250 mL) = (2,000 units) / (x mL)
Solving for x, we get:
x = (2,000 units x 250 mL) / 25,000 units x = 20 mL

Correct Answer is D
Explanation
A) Polyethylene Glycol: Polyethylene glycol is a medication typically used to treat constipation by promoting bowel movements. While it can be useful in managing constipation, it is not commonly prescribed after a myocardial infarction. In this situation, the focus is more on medications that promote heart health, reduce cardiac workload, and prevent complications related to the heart attack.
B) Bisacodyl: Bisacodyl is a stimulant laxative used to relieve constipation. However, this medication is not typically prescribed immediately following a myocardial infarction. Stimulant laxatives can cause dehydration and excessive fluid shifts, which can be harmful to a client recovering from a heart attack. The focus would be on safer options for bowel management in this context.
C) Senna: Senna is also a stimulant laxative, used for relieving constipation. Similar to bisacodyl, it is not ideal for clients who have recently experienced a myocardial infarction due to its potential for causing dehydration and electrolyte imbalances, which could negatively affect heart function. A gentler approach to bowel management is preferred for these clients.
D) Docusate Sodium: Docusate sodium is a stool softener commonly prescribed to prevent constipation, especially in clients who have recently had a myocardial infarction. After a heart attack, it's important to avoid straining during bowel movements, as this could increase pressure on the heart. Docusate sodium helps soften stools and promotes smoother bowel movements without stimulating the gastrointestinal system in a way that would elevate cardiac stress. It is the most appropriate choice for this client.
