1. A client does not understand why vision loss due to glaucoma is irreversible. What is the nurse's best explanation?

A. Once retinal detachment occurs, it does not return to its normal state
B. Once the tissue has necrosed from high-pressure, it does not regenerate
C. Glaucoma always leads to permanent blindness
D. Once bacterial infection has caused damage, the tissue does not regenerate

Correct answer: B

Rationale: The correct explanation for irreversible vision loss in glaucoma is that once the tissue has necrosed from high pressure, it does not regenerate. This necrosis occurs due to the damage caused by increased intraocular pressure, which leads to irreversible damage to the optic nerve and retinal tissue. Choices A, C, and D are incorrect because they do not directly address the specific mechanism of irreversible vision loss in glaucoma, which is necrosis due to high pressure.

2. What is the most common method of reducing and immobilizing a fracture?

A. Open reduction with external fixation
B. External reduction and internal fixation
C. External fixation with closed reduction
D. Open reduction with internal fixation

Correct answer: D

Rationale: Open reduction with internal fixation (ORIF) is the most common method for reducing and immobilizing fractures.

3. Which test is used in the diagnosis of osteoporosis?

A. Phalen's maneuver
B. Dual-energy X-ray absorptiometry (DXA) scan
C. Proprioception
D. Blood culture

Correct answer: B

Rationale: The correct answer is B, Dual-energy X-ray absorptiometry (DXA) scan, which is commonly used to diagnose osteoporosis by measuring bone mineral density. Phalen's maneuver (choice A) is a test used to assess for carpal tunnel syndrome and is not related to osteoporosis. Proprioception (choice C) refers to the sense of body position and is not a diagnostic test for osteoporosis. Blood culture (choice D) is used to detect infections caused by bacteria in the bloodstream and is not relevant to the diagnosis of osteoporosis.

4. What is accurate health promotion teaching to prevent ear infection or trauma? (Select all that apply)

A. Blow nose gently without blocking nostrils
B. Wear hearing protection when exposed to loud noise
C. Avoid using cotton-tipped applicators to clean the external ear
D. All of the above

Correct answer: D

Rationale: The correct health promotion teachings to prevent ear infection or trauma include blowing the nose gently without blocking nostrils, wearing hearing protection when exposed to loud noise, and avoiding the use of cotton-tipped applicators to clean the external ear. Blocking one nostril when blowing the nose is incorrect, as it can cause problems. Therefore, choice A is inaccurate. Additionally, using cotton-tipped applicators to clean the external ear can lead to trauma or infection, making choice C a correct preventive measure.
