DIABETIC FOOT ULCER QUIZ / TEST
DIABETIC FOOT ULCER a very common problem. Here is the MCQs test on DIABETIC FOOT ULCER as quiz or test. These MCQs are prepared to fulfil the requirement for all types of medical exams as NEET, USMLE, PLAB, Promatric and ALL TYPES OF MEDICAL BOARD Exams all over the world.
Results
#1. A 60-year-old diabetic patient has a non-healing ulcer with exposed bone. An X-ray shows periosteal reaction. What is the most likely diagnosis? ? Osteomyelitis is likely when an ulcer exposes bone, and X-ray shows periosteal reaction. MRI or bone biopsy confirms it.

#2. Which preventive measure is most effective for diabetic foot ulcers? ? MCR shoes redistribute pressure and prevent trauma, reducing ulcer risk in neuropathic patients.
MCR shoes redistribute pressure and prevent trauma, reducing ulcer risk in neuropathic patients.
#3. A diabetic ulcer is found to have underlying osteomyelitis. What is the best diagnostic investigation? ? MRI is the most sensitive imaging modality for detecting osteomyelitis in diabetic foot ulcers.
MRI is the most sensitive imaging modality for detecting osteomyelitis in diabetic foot ulcers.
#4. What is the first-line treatment for a diabetic foot ulcer with cellulitis? ? Broad-spectrum antibiotics (e.g., amoxicillin-clavulanate) are first-line for diabetic foot infections due to polymicrobial involvement.
Broad-spectrum antibiotics (e.g., amoxicillin-clavulanate) are first-line for diabetic foot infections due to polymicrobial involvement.
#5. A diabetic patient presents with a gangrenous toe and absent pedal pulses. What is the most likely additional finding? ? Gangrene with absent pulses suggests peripheral arterial disease (PAD), often due to atherosclerosis (e.g., popliteal artery stenosis).
Gangrene with absent pulses suggests peripheral arterial disease (PAD), often due to atherosclerosis (e.g., popliteal artery stenosis).
#6. A diabetic patient’s foot is warm, erythematous, and swollen without ulceration. X-ray shows fractures and joint disorganization. What is the diagnosis? ? Charcot neuroarthropathy presents with a warm, deformed foot due to neurotrauma and fractures, often mistaken for infection.
Charcot neuroarthropathy presents with a warm, deformed foot due to neurotrauma and fractures, often mistaken for infection.
#7. Which of the following is the most appropriate first-line management for a Wagner grade 3 diabetic foot ulcer with exposed bone? ? Wagner grade 3 ulcers with bone involvement require aggressive management with surgical debridement and IV antibiotics to treat underlying osteomyelitis.
Wagner grade 3 ulcers with bone involvement require aggressive management with surgical debridement and IV antibiotics to treat underlying osteomyelitis.
#8. A 55-year-old diabetic patient presents with a non-healing ulcer on the plantar aspect of the foot. The ulcer is painless, deep, and surrounded by callus. What is the most likely underlying cause? ? A painless, deep plantar ulcer in a diabetic patient is classic for neuropathic ulceration due to sensory neuropathy, leading to unnoticed trauma and callus formation.
A painless, deep plantar ulcer in a diabetic patient is classic for neuropathic ulceration due to sensory neuropathy, leading to unnoticed trauma and callus formation.
#9. Which of the following is the most common organism causing diabetic foot infections? ? Staphylococcus aureus is the most common cause, but diabetic foot infections are often polymicrobial.
Staphylococcus aureus is the most common cause, but diabetic foot infections are often polymicrobial.
#10. Which nerve is most commonly affected in diabetic sensory neuropathy, leading to plantar ulcers? ? The medial and lateral plantar nerves (branches of the tibial nerve) are often affected, causing loss of protective sensation in the sole.
The medial and lateral plantar nerves (branches of the tibial nerve) are often affected, causing loss of protective sensation in the sole.
#11. What is the most reliable clinical sign differentiating Charcot foot from cellulitis in a diabetic patient? ? While both may present with warmth and swelling, Charcot foot typically maintains intact skin, whereas cellulitis often has skin breakdown or penetrating wounds.
While both may present with warmth and swelling, Charcot foot typically maintains intact skin, whereas cellulitis often has skin breakdown or penetrating wounds.
#12. A diabetic patient develops claw toes and a loss of foot arch. Which type of neuropathy is responsible? ? Motor neuropathy causes paralysis of intrinsic foot muscles, leading to claw toes, hammer toes, and loss of the longitudinal arch.
Motor neuropathy causes paralysis of intrinsic foot muscles, leading to claw toes, hammer toes, and loss of the longitudinal arch.
#13. Why are diabetic patients more prone to infections? ? High tissue glucose provides a favorable environment for bacterial growth. Additionally, impaired leukocyte function and microangiopathy contribute to infection risk.
High tissue glucose provides a favorable environment for bacterial growth. Additionally, impaired leukocyte function and microangiopathy contribute to infection risk.
#14. Which test is most useful to assess peripheral arterial disease (PAD) in a diabetic foot ulcer? ? ABI screens for PAD. ABI <0.9 indicates arterial insufficiency, but calcified vessels may give falsely elevated values.
ABI screens for PAD. ABI <0.9 indicates arterial insufficiency, but calcified vessels may give falsely elevated values.
#15. Which of the following is a feature of autonomic neuropathy in diabetes? ? Autonomic neuropathy leads to anhidrosis (reduced sweating), causing dry, cracked skin prone to breakdown.
Autonomic neuropathy leads to anhidrosis (reduced sweating), causing dry, cracked skin prone to breakdown.
