A nurse is teaching a client who is scheduled for dual-energy x-ray absorptiometry (DXA) to screen for osteoporosis. Which of the following instructions should the nurse include in the teaching?
"You will need to fast for 12 hours before the test."
"You will need to lie flat for 4 hours following the test."
"You will need to remove all jewelry before the test."
"You will need to empty your bladder before the test."
The Correct Answer is C
A. Fasting is not necessary for a dual-energy x-ray absorptiometry (DXA) scan, as it does not involve ingesting anything.
B. The client does not need to lie flat for an extended period following a DXA scan. They can resume normal activities immediately after the test.
C. The nurse should instruct the client to remove all jewelry or metal objects that can interfere with the test. A DXA scan is the mostly commonly used screening and diagnostic tool for measuring bone mineral density.
D. . It is not necessary to empty the bladder before the test.

Correct Answer is B
Explanation
A. Inserting sterile packing into the nares is not indicated in this situation. Clear fluid drainage from the nose may be cerebrospinal fluid (CSF), and packing could cause further complications.
B. Allowing the drainage to drip onto a sterile gauze pad is the appropriate initial action. Clear fluid drainage from the nose after a traumatic event may be CSF, which can indicate a skull fracture and damage to the meninges. Collecting the fluid on a sterile gauze pad can help confirm the presence of CSF.
C. Suctioning the nose with a bulb syringe is not recommended because it can introduce contaminants into the nasal passages and potentially worsen the injury.
D. Obtaining a culture of the specimen using sterile swabs is a consideration once the presence of CSF is confirmed. However, the initial priority is to identify and collect the clear fluid drainage.
Correct Answer is C
Explanation
A. Stating that ibuprofen is the first step in medication therapy for osteoarthritis is not an accurate statement. Medication choices should be made in consultation with a healthcare provider, and different medications may be prescribed based on individual needs.
B. Elevating the legs with pillows is generally not a specific intervention for osteoarthritis in the knees. While elevation can help with other conditions, it is not a primary recommendation for managing knee osteoarthritis.
C. Using either heat or ice can be helpful in relieving discomfort associated with osteoarthritis. This statement indicates an understanding of self-care strategies for managing symptoms.
D. Limiting physical activity is not typically recommended for osteoarthritis management. In fact, regular and appropriate physical activity can be beneficial for maintaining joint function and reducing pain in individuals with osteoarthritis.
