Heterotopic Ossificans Risk

Question 1

Which patient has the GREATEST risk of developing heterotopic ossificans?
Options:

  • a. A patient pre-treated with intravenous antibiotics prior to surgery
  • b. A patient undergoing total hip replacement surgery
  • c. A patient with a past medical history of MRSA
  • d. A patient with rheumatoid arthritis

Explanation

Heterotopic ossificans is a condition characterized by the formation of bone in tissues where bone normally does not exist. Patients undergoing certain surgeries, particularly total hip replacement surgeries, are at a heightened risk due to the involvement of the hip joint and associated trauma. Thus, option b is the correct answer, identifying the patient undergoing total hip replacement surgery as having the greatest risk.

Kidney Damage Indicators

Question 2

What combination of signs and symptoms indicate kidney damage as a result of rapid breakdown of skeletal muscle?
Options:

  • a. Abnormal bloodwork (ANA, SED) and dark urine
  • b. Abnormal bloodwork (BUN, CPK) and dark urine
  • c. Tachycardia, normal bloodwork, and blood in urine
  • d. Tachycardia, normal bloodwork, and dark urine

Explanation

Kidney damage due to rapid breakdown of skeletal muscle, often resulting from conditions such as rhabdomyolysis, can lead to abnormal enzyme levels in the blood and changes in urine color. The most indicative combination of symptoms includes elevated blood urea nitrogen (BUN) and creatine phosphokinase (CPK) levels along with dark urine, highlighting option b as correct.

Malignant Orthopedic Neoplasms

Question 3

Which of the following malignant orthopedic neoplasms primarily affects children and young adults and can result in pathologic fractures of the long bones?
Options:

  • a. Ewing's sarcoma
  • b. Multiple myeloma
  • c. Osteoid osteoma
  • d. Osteosarcoma

Explanation

Ewing's sarcoma and osteosarcoma are two notable malignant bone tumors that primarily affect younger populations. Osteosarcoma is particularly prevalent among adolescents and is known to cause pathologic fractures in long bones due to its aggressive nature. Therefore, the correct answer is d. Osteosarcoma.

Knee Pain Assessment

Question 4

A 65-year-old reports left knee pain that increases when standing and bending and resolves with rest. The patient reports audible clicking and feels "grinding" sensations in the knee. What condition is MOST associated with these signs and symptoms?
Options:

  • a. Compartment syndrome
  • b. Osteoarthritis
  • c. Osgood Schlatter's
  • d. Septic arthritis

Explanation

The described symptoms—pain that worsens with activity and clicking or grinding in the knee—are characteristic of osteoarthritis, a degenerative joint disease. Thus, option b is the correct answer, indicating osteoarthritis as the condition most associated with the patient’s symptoms.

Long Bone Procedures

Question 5

What surgical procedure would be MOST associated with malignant neoplasms of the long bones of the lower extremity and used to salvage the ankle so it could be used as a functioning knee joint?
Options:

  • a. Arthroplasty
  • b. Fasciotomy
  • c. Kyphoplasty
  • d. Rotationplasty

Explanation

Rotationplasty is a unique surgical procedure often employed in cases of malignant tumors of the knee area, allowing the ankle to function as a knee joint when the knee has been resected due to tumor involvement. Therefore, the correct answer is d. Rotationplasty.

Osteoporosis Management

Question 6

A 65-year-old female with a t-score of -2.5 would benefit MOST from which of the following combinations of medical interventions?
Options:

  • a. Increased calcium and vitamin D, regular resistance training
  • b. Increased iron and regular cardiovascular exercise
  • c. Increased calcium, decreased vitamin D, regular resistance training
  • d. Rest, ice, compression, elevation

Explanation

A t-score of -2.5 indicates osteoporosis, and the best interventions involve bolstering bone health through calcium and vitamin D supplementation combined with regular weight-bearing exercise such as resistance training. This supports bone density. Thus, the correct option is a. Increased calcium and vitamin D, regular resistance training.

  • b. Femoral neck, proximal femur, femoral condyles
  • c. Pelvis, sacrum, tibial plateau
  • d. Scaphoid, femoral head, tibial plateau, talus

Explanation

Avascular necrosis typically occurs in areas with a limited blood supply. Critical sites include the femoral head and neck as these regions are particularly at risk. Therefore, the correct answer is d. Scaphoid, femoral head, tibial plateau, talus noting the high risk of avascular necrosis in these locations.
