A heparin infusion is prescribed for a client who weighs 220 pounds. After administering a bolus dose of 80 units/kg, the nurse calculates the infusion rate for the heparin solution at 18 units/kg/hour. The available solution is "Heparin Sodium 25,000 Units in 5% Dextrose Injection 250 mL". The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["18"]
Calculation:
- Convert the client's weight from pounds (lb) to kilograms (kg).
The client's weight is 220 lb.
Client weight (kg) = 220 lb/2.2 lb/kg
= 100 kg.
- Calculate the total heparin dose to be administered per hour (units/hr).
The ordered rate is 18 units/kg/hour.
Total dose rate (units/hr) = 18 units/kg/hour×100 kg
= 1800 units/hr.
- Determine the concentration of the available solution (units/mL).
Available solution is 25,000 units in 250 mL.
Concentration (units/mL) = 25,000 units/250 mL
= 100 units/mL.
- Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total dose rate (units/hr)/Concentration (units/mL)
= 1800 units/hr/100 units/mL
= 18 mL/hr.

Correct Answer is D
Explanation
A. Offer to discuss the client's health status with each of the adult children: While involving family in discussions is important, the immediate question from the spouse is about recognizing signs of imminent death. Directly explaining the physiological changes is more appropriate at this moment.
B. Reassure the spouse that the healthcare provider (HCP) will notify when to call the children: Waiting for the HCP to give a signal does not provide the spouse with the knowledge they are seeking. It may delay preparation and increase anxiety during the final hours.
C. Gather information regarding how long it will take for the children to arrive: While logistical planning is helpful, it does not address the spouse’s question about recognizing imminent death and understanding what to expect.
D. Explain that the client will start to lose consciousness and the body systems will slow down: Providing clear, compassionate information about the expected signs of dying helps the spouse recognize that death is near, allows family members to prepare emotionally, and facilitates meaningful final interactions with the client.
Correct Answer is B
Explanation
A. Plumb line test indicates fetal position curvature: This assessment is used to evaluate spinal alignment and posture, not hip integrity. It does not explain asymmetrical buttocks in a newborn.
B. Ortolani maneuver causing a click at the hip joint: A positive Ortolani sign (a “click” or “clunk”) indicates hip dysplasia or subluxation. This finding is significant and should be reported to the healthcare provider for further evaluation and management.
C. Babinski test that reveals fanning out of toes: The Babinski reflex is normal in newborns and does not indicate musculoskeletal abnormality. It is unrelated to asymmetrical buttocks.
D. Moro test precipitating a startle response: The Moro reflex is a normal newborn response and does not indicate hip instability or asymmetry in the buttocks.
