A client who weighs 110 lb receives a prescription for dalteparin 150 units/kg SUBQ daily for 4 months. The medication is available in 7,500 units/0.3 mL prefilled syringe. How many mL should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["0.3"]
Calculation:
- Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 110 lb / 2.2 lb/kg
= 50 kg.
- Calculate the total units of dalteparin the client should receive daily.
Daily units = Desired units/kg × Weight (kg)
= 150 units/kg × 50 kg = 7500 units.
- Determine the volume to administer based on the available prefilled syringe.
The medication is available in a 7,500 units/0.3 mL prefilled syringe.
Since the calculated daily dose (7500 units) exactly matches the units in one prefilled syringe (7500 units), the volume to administer is the volume of that syringe.
Volume to administer:
= 0.3 mL.

Correct Answer is D
Explanation
Rationale:
A. Balance and posture: Although relevant for general mobility, a trapeze bar is primarily used while in bed, where balance and posture are less critical than the strength to use the device effectively.
B. Risk for disuse syndrome: This risk supports the need for mobility aids like a trapeze, but it does not determine whether the client can use the device safely and independently.
C. Pressure sore risk: This is important for overall care planning, but not the most relevant assessment for determining safe and effective trapeze use.
D. Upper body muscle strength: Adequate arm and shoulder strength are essential for the client to grasp and lift themselves using the trapeze bar. Without this, using the bar could lead to falls or injuries.
Correct Answer is ["125"]
Explanation
Calculation:
- Convert the total volume from liters (L) to milliliters (mL).
Total volume = 1 L × 1000 mL/L
= 1000 mL.
Infusion time = 8 hours.
- Calculate the infusion rate in milliliters per hour (mL/hour).
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hour)
= 1000 mL / 8 hours
= 125 mL/hour.
Answer: 125
