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. A nurse is caring for a client who has acute osteomyelitis. Which of the following interventions is the nurse's priority?

A. Administer antibiotics to the client
B. Increase the client's protein intake
C. Teach relaxation breathing to reduce the client's pain
D. Provide the client with anti-pyretic therapy

Correct answer: A

Rationale:

3. A client sustained a crushing injury to his right arm during a car accident. He arrives to the emergency room complaining of numbness in his right hand. He has no other injuries. What should the nurse do first?

A. Assess the right radial pulse
B. Call the provider
C. Administer pain medication
D. Assess the right pedal pulse

Correct answer: A

Rationale: Assessing the radial pulse checks for adequate circulation and potential complications.

4. 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.
