1. A nurse assesses an audible grating sound (Crepitus) when a client with osteoarthritis moves his knees. What is the cause of this sound?

A. A herniated disk in the diseased joint
B. Pieces of bone and cartilage floating
C. Popping bursae from standing
D. Years of an autoimmune process

Correct answer: A

Rationale:

2. A client does not understand why vision loss due to glaucoma is irreversible. What is the best explanation?

A. Once bacterial infection has caused damage, the tissue does not regenerate.
B. Once retinal detachment occurs, it does not return to its normal state.
C. Too many nerve fibers have become ischemic and died, so vision loss is permanent.
D. Glaucoma always leads to permanent blindness.

Correct answer: C

Rationale: The correct answer is C. In glaucoma, the optic nerve damage due to high intraocular pressure leads to permanent vision loss because the nerve fibers do not regenerate. Choice A is incorrect as it discusses bacterial infection, not relevant to glaucoma. Choice B is incorrect because it refers to retinal detachment, not glaucoma. Choice D is incorrect because not all glaucoma cases lead to permanent blindness; vision loss can be prevented or slowed with treatment.

3. What steps are NOT included in preparing a sterile field?

A. Do not turn away from the sterile field
B. Obtain PAPR mask
C. Prepare the client before setting up the sterile field
D. Cover the sterile field once it is set up

Correct answer: B

Rationale:

4. The client states, â€œthe doctor says I am nearsighted. I do not get it.â€ What would be the best response by the nurse?

A. I am sorry you did not understand. Would you like a different doctor?
B. Nearsighted, or myopia means that you have difficulty seeing things at a distance.
C. You will need to have glasses.
D. This means you wonâ€™t ever need glasses.

Correct answer: B

Rationale: The correct response is to explain to the client what nearsightedness means, which is having difficulty seeing distant objects, as known as myopia. Choice A is not helpful as changing doctors is not necessary for this situation. Choice C is premature as wearing glasses is a possible solution but not the only one. Choice D is incorrect as nearsightedness (myopia) often requires glasses for correction.
