A nurse is preparing to administer 0.9% sodium chloride IV infusion 1000 mL bag at a rate of 200 mL/hr for a client who has rhabdomyolysis.

The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number.

(Use a leading zero if it applies. Do not use a trailing zero)

Choice A rationale
Applying an ice pack to painful joints can help reduce inflammation and numb the area, providing temporary pain relief. However, it is not a recommended long-term strategy for managing osteoarthritis pain. Heat therapy is often more effective for chronic pain associated with osteoarthritis.
Choice B rationale
Taking aspirin on days with more pain is not recommended for osteoarthritis management. Aspirin is an NSAID and can cause gastrointestinal side effects with long-term use.
Acetaminophen is preferred for managing osteoarthritis pain due to its lower risk of side effects.
Choice C rationale
Increasing water intake to 2 liters per day is beneficial for overall health and can help maintain joint lubrication. Proper hydration is important for joint health and can help reduce the risk of further joint damage.
Choice D rationale
High-impact aerobics are not recommended for individuals with osteoarthritis as they can exacerbate joint pain and damage. Low-impact exercises such as swimming, cycling, and walking are better options for maintaining joint mobility and reducing pain.

Choice A rationale
Monitoring the puncture site for hematoma is crucial because a hematoma can indicate bleeding at the puncture site, which can lead to complications such as infection or nerve damage. Hematomas can also cause increased intracranial pressure, which can be dangerous for the patient. Therefore, it is essential to monitor the site closely to ensure that any signs of bleeding are detected early and managed appropriately.
Choice B rationale
Elevating the client’s head of bed is incorrect because it can increase the risk of cerebrospinal fluid (CSF) leakage from the puncture site. After a lumbar puncture, it is recommended to keep the patient in a flat position for several hours to reduce the risk of post-lumbar puncture headache and to allow the puncture site to heal properly. Elevating the head of the bed too soon can disrupt this process and lead to complications.
Choice C rationale

Inserting a urinary catheter is incorrect because it is not a standard procedure following a lumbar puncture. The primary focus after a lumbar puncture is to monitor for complications related to the procedure itself, such as bleeding, infection, or CSF leakage. Inserting a urinary catheter is not necessary unless there is a specific indication for it, such as urinary retention or other urological issues.
Choice D rationale
Encouraging fluid intake is correct because it helps to replenish the CSF that was removed during the lumbar puncture. Increased fluid intake can also help to reduce the risk of post- lumbar puncture headache, which is a common complication. Hydration is important for overall recovery and helps to maintain normal bodily functions.
Choice E rationale
Applying a cervical collar to the client is incorrect because it is not related to the care of a lumbar puncture site. A cervical collar is typically used for patients with neck injuries or conditions affecting the cervical spine. It has no role in the management of a lumbar puncture site and would not provide any benefit in this context.
