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.

What should be done immediately after an ankle injury?
- A. Immobilize, heat, compress, and elevate the ankle
- B. Rest, ice, compress, and lower the ankle
- C. Rest, ice, compress, and elevate the ankle
- D. Rest, incubate, confine, and lower the ankle
Correct Answer: C
Rationale: The correct answer is C: Rest, ice, compress, and elevate the ankle. After an ankle injury, it is essential to follow the RICE method (Rest, Ice, Compression, Elevation) for immediate treatment. Resting the injured ankle helps prevent further damage, applying ice reduces swelling and pain, compression with a bandage provides support and helps control swelling, and elevating the ankle above heart level reduces swelling by allowing fluid to drain away from the injury site. Choices A, B, and D are incorrect because heating, incubating, or confining the ankle can worsen the injury by increasing swelling and inflammation instead of reducing them.

Correct Answer: D

The provider orders the client to be placed in a high-Fowler's position. At what angle will the nurse position the client?
- A. 15 degrees
- B. 0 degrees
- C. 90 degrees
- D. 30 degrees
Correct Answer: C
Rationale: The correct answer is C: 90 degrees. In a high-Fowler's position, the client's head of the bed is raised to a 90-degree angle. This positioning helps improve breathing and facilitates eating and talking. Choice A, 15 degrees, is incorrect as it is not high enough to be considered a high-Fowler's position. Choice B, 0 degrees, is incorrect as it represents a flat or supine position. Choice D, 30 degrees, is also incorrect as it does not meet the criteria for a high-Fowler's position.
