A nurse is preparing to administer a continuous heparin infusion at 1600 units/hr. Available is heparin 25.000 units in dextrose 5% in water (DSW) 500 mL The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["32"]
1. Determine the concentration of heparin in the solution:
- There are 25,000 units of heparin in 500 mL of D5W.
- Concentration = 25,000 units / 500 mL = 50 units/mL.
2. Calculate the required mL/hr for the desired infusion rate:
- The order is for 1600 units/hr.
- To find the mL/hr:
ML/HR=desired units/hr divided by unts/ml
=1600/50
=32ml/hr

Correct Answer is B
Explanation
A. Remain on bedrest for the first 24 hr.: This is not recommended after arthroscopic knee surgery. Early mobilization and ambulation are encouraged to prevent complications such as blood clots and promote healing.
B. Apply ice to the affected area: This is an important instruction. Applying ice can help reduce swelling and pain after surgery. It's typically recommended for the first 24-48 hours.
C. Begin active range of motion: While range of motion exercises are important, they should be initiated as directed by the healthcare provider, and they should be done gently to avoid straining the surgical site.
D. Keep the leg in a dependent position: This is not recommended. Elevating the leg can help reduce swelling and promote circulation. Keeping the leg in a dependent position could exacerbate swelling and discomfort.
Correct Answer is B
Explanation
A. Drying time is typically shorter with a synthetic cast compared to a plaster cast. Synthetic casts are designed to set faster, reducing the time the patient needs to remain immobilized during casting.
B. A synthetic cast is generally lighter in weight than a plaster cast. This can be more comfortable for the patient and may reduce the risk of muscle atrophy or discomfort associated with the cast's weight.
C. A plaster cast does not necessarily require expensive equipment for application, and both plaster and synthetic casts can be applied using relatively simple and cost-effective methods.
D. The effectiveness of immobilization is not significantly different between plaster and synthetic casts. Both types of casts can provide adequate immobilization for bone fractures, and the choice between them may depend on factors like patient preference, the type of fracture, and other clinical considerations.
