Administer heparin 1000 units per hour IV. The pharmacy supplies the heparin infusion as 25.000 units in 500 mL DSW. What will the IV pump be set to? (Include unit of measure with answer).
The Correct Answer is ["20"]
Heparin infusion calculation:
- Heparin dose ordered: 1000 units per hour
- Heparin concentration: 25,000 units in 500 mL
- Conversion: 1 mL = 500 units
Calculations:
- Units per hour = 1000 units
- Units per mL = 25,000 units / 500 mL = 50 units/mL
- mL per hour = 1000 units / 50 units/mL = 20 mL/hr
Answer: The IV pump should be set to 20 mL/hr.

Correct Answer is A
Explanation
A. "Medication is usually not prescribed to treat oppositional defiant disorder. Let's discuss some behavioral strategies you can use." Behavioral interventions are the mainstay of treatment for ODD. Medications are not typically recommended unless there are comorbid conditions like ADHD or aggression that do not respond to behavioral interventions alone.
B. There are many medications that will help your child manage aggression and destructiveness. The health care provider will discuss them with you: This statement is misleading as medications are not first-line for ODD.
C. "Medication is not used to treat this oppositional defiant disorder because it is behavioral in nature.": This is an oversimplification; while primarily behavioral, medications might be considered in certain cases.
D. "It's a common misconception that there is a medication available to treat every health problem.": This statement dismisses the possibility of appropriate medication when needed.
Correct Answer is C
Explanation
A. Xerostomia: Dry mouth, not typically associated with DIC.
B. Bradycardia: Not typically seen in DIC; usually, there is tachycardia due to the underlying condition.
