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.

Explanation
A. Low socioeconomic status: Low socioeconomic status can contribute to stressors and lack of resources, increasing the risk of abusive behaviors like shaking. Stressors related to poverty and inadequate support systems can contribute to caregiver frustration and abuse.
B. Inadequate parental education: Education levels can influence parenting practices but are not as directly linked to the physical act of shaking.
C. Having multiple siblings: Having multiple children does not directly increase the risk of shaking unless coupled with other stressors.
D. Physical disability of the caregiver: While disabilities can pose challenges, they do not inherently increase the risk of shaking a child.
