A patient presents with a Colles' fracture. What is the characteristic deformity associated with this type of fracture?

Correct Answer: A

Rationale: Colles' fracture is a type of distal radius fracture characterized by a break of the radius bone in the forearm close to the wrist. In a Colles' fracture, the distal fragment of the fractured radius bone gets displaced dorsally, meaning it shifts upwards towards the back of the hand, creating a characteristic "dinner fork" deformity when viewed from the side. This dorsal displacement results in a visible bump on the back of the wrist and a noticeable deformity when compared to the uninjured side.

Correct Answer: D

Rationale: A trimalleolar fracture is characterized by fractures involving the lateral malleolus (distal fibula), medial malleolus (distal tibia), and the posterior tubercle of the distal tibia. This fracture pattern results in instability of the ankle joint and is often associated with widening of the ankle mortise on X-ray. The deformity and swelling seen in this patient are indicative of a trimalleolar fracture and are typically caused by a high-energy injury, such as a forceful twisting motion. Treatment for trimalleolar fractures often involves surgical intervention to stabilize the ankle joint and restore normal function.

Correct Answer: C

Rationale: The patient's presentation of urinary frequency, urgency, dysuria, and suprapubic pain along with the urinalysis findings of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) are highly suggestive of a urinary tract infection (UTI). UTIs are one of the most common types of bacterial infections seen in clinical practice. The symptoms described are classic for a lower urinary tract infection. The presence of pyuria and bacteriuria on urinalysis further supports the diagnosis of a UTI. Acute glomerulonephritis typically presents with hematuria, proteinuria, hypertension, and edema. Chronic kidney disease is often asymptomatic in early stages and presents with symptoms like fatigue, edema, and changes in urination later on. Renal calculi are associated with severe colicky flank pain that can radiate to the groin, and they may present with

Correct Answer: A

Rationale: The clinical presentation of gross hematuria, flank pain, palpable abdominal mass, along with imaging findings of a large heterogeneous renal mass with necrosis and calcifications are highly suggestive of renal cell carcinoma (RCC). RCC is the most common type of kidney cancer in adults. The presence of necrosis and calcifications are characteristic features of RCC. Imaging modalities such as CT scans or MRI can confirm the diagnosis by showing the typical features of RCC, including a solid mass with areas of necrosis and calcifications. It is important to further evaluate this patient, likely with a biopsy, to confirm the diagnosis and determine the extent of the disease for appropriate management.

Correct Answer: C

Rationale: Prostatitis is characterized by inflammation of the prostate gland, leading to symptoms such as dysuria (painful urination), urinary frequency, urinary urgency, and perineal or pelvic pain. Prostate cancer, on the other hand, is characterized by the presence of malignant cells in the prostate gland and may not present with these typical symptoms. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland that can cause urinary symptoms but is not typically associated with inflammation. Urethritis refers to inflammation of the urethra, which is a different condition and may present with symptoms such as painful urination and discharge from the urethra.
