Mr. Jones presents to the clinic with extreme pain in his left arm. During your assessment, you notice that he has a prosthetic left arm (from the shoulder down). What explanation can you provide for Mr. Jones reporting extreme pain in his left arm?
Nerve damage from the prosthetic
Heart attack referred pain
Muscle strain in the remaining part of the arm
Phantom limb pain
The Correct Answer is D
Choice A reason: Nerve damage from the prosthetic may cause local discomfort, but pain in the entire absent arm suggests phantom limb pain. This is less likely than neural misfiring, so it’s incorrect.
Choice B reason: Heart attack referred pain typically affects the left arm but is unlikely in a prosthetic limb. Phantom limb pain explains pain in the absent arm, so this is incorrect.
Choice C reason: Muscle strain affects existing muscles, not a prosthetic arm. Phantom limb pain, from neural signals in the brain, explains pain in the missing limb, so this is incorrect.
Choice D reason: Phantom limb pain occurs when the brain perceives pain in an amputated limb, common in prosthetic users. This matches Mr. Jones’s pain in his prosthetic arm, making it correct.

Correct Answer is B
Explanation
Choice A reason: Vitamin D deficiency affects calcium and bone health, not creatinine or BUN levels, which reflect kidney function. Elevated BUN and creatinine point to dehydration or kidney issues, so this is incorrect for the lab findings.
Choice B reason: Elevated creatinine and BUN indicate dehydration or kidney dysfunction, as these markers rise when kidneys fail to clear waste or when blood volume is low. This matches the patient’s symptoms, making it the correct choice.
Choice C reason: Respiratory acidosis affects blood pH and CO2, not creatinine or BUN, which are renal markers. Kidney dysfunction or dehydration better explain the lab results, so this is incorrect for the findings.
Choice D reason: Liver failure may elevate other markers (e.g., bilirubin), but BUN and creatinine are kidney-specific. Dehydration or kidney dysfunction align with the labs and symptoms, so this is incorrect.
Correct Answer is D
Explanation
Choice A reason: Septic arthritis affects joints, causing joint-specific swelling and pain, but this patient’s symptoms center on a fracture site, suggesting bone involvement. Osteomyelitis better matches pain, swelling, and warmth over a bone wound, with fever and chills, so this is incorrect.
Choice B reason: Rheumatoid arthritis is a chronic autoimmune condition affecting multiple joints, typically hands and feet, not a single fracture site. This patient’s acute fever, localized bone pain, and wound-related symptoms point to osteomyelitis, not systemic arthritis, making this incorrect.
Choice C reason: Gout causes acute joint pain, often in the big toe, due to uric acid crystals, not bone infections. The patient’s fracture site pain, swelling, and systemic symptoms like fever align with osteomyelitis, not gout, so this is incorrect.
Choice D reason: Osteomyelitis, a bone infection, matches the patient’s severe pain, swelling, warmth, and redness over a recent fracture site, with fever and chills. These are primary signs of bone infection post-trauma, making this the correct diagnosis and symptom description.
