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).
Answer and Explanation

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. Areas of ecchymosis on the torso. Ecchymosis on the torso, especially in non-ambulatory children, can be concerning for abuse. Unexplained bruises in unusual locations or patterns are red flags for physical abuse.

B. Mismatched clothing: Typically not an indicator of abuse but could suggest neglect.

C. Abrasions on knees: Common in active children and not specific to abuse.

D. Abdominal rebound tenderness: Could indicate abdominal pathology but not necessarily abuse.

E. Round burn marks on forearms: Could suggest burns but not specific to abuse without further context.

Correct Answer is D

Explanation

A. The child was not promoted to the next grade: Academic performance alone does not directly correlate with conduct disorder.

B. The child moved to three new homes over a two-year period: Transience can contribute to instability but is not a direct risk factor for conduct disorder.

C. The child's best friend was absent from the child's birthday party: Social relationships are important, but absence from a birthday party is not a significant risk factor for conduct disorder.

D. The child has been raised by a parent who has recurring major depressive disorder. Exposure to parental mental illness, such as major depressive disorder, can create stressful family environments that contribute to the development of conduct disorder.
