Answer: (C)

Explicación

Urinary retention is defined as the inability to empty the bladder completely or at all, accompanied by signs such as dysuria, stranguria, absence of attempts to urinate, enlarged bladder, weak urine stream, or bladder rupture, exactly as described in the source excerpt. Review: Urinary retention: causes, diagnosis, and treatment options. Course evidence: "Urinary retention : A clinical condition characterized by inability to empty the bladder completely or at all, presenting with signs such as dysuria, stranguria, absence of attempts to urinate, enlarged bladder, weak urine stream, or bladder rupture."

5. What is the primary role of repeated staging every 3-4 months in the clinical management of progressive Chronic Kidney Disease (CKD)?

A. To diagnose acute kidney infections distinct from CKD

B. To initiate advanced therapies such as hemodialysis

C. To monitor disease progression and adjust therapy accordingly

D. To provide nutritional support through feeding tubes

Answer: (C)

Explicación

Repeated staging every 3-4 months is used to monitor progression of CKD and adjust therapy, as explicitly stated in the source excerpt. The other options describe different functions not linked to repeated staging. Review: Chronic Kidney Disease (CKD) clinical management and staging. Course evidence: "A progressive kidney disorder characterized by decreased renal function over time, requiring repeated staging every 3-4 months to monitor progression and adjust therapy."

6. How do the arguments for and against decompressive cystocentesis differ in the management of urethral obstruction?

A. Arguments for claim decompressive cystocentesis prevents urinary tract infections, while arguments against claim it causes infections

B. Arguments for focus on long-term kidney function improvement, while arguments against focus on short-term pain relief

C. Arguments for suggest decompressive cystocentesis cures urethral obstruction, while arguments against state it has no therapeutic effect

D. Arguments for emphasize immediate bladder emptying and facilitation of catheterization, while arguments against highlight risks of bladder trauma and potential delays in catheter placement

Answer: (D)

Explicación

The source explicitly lists arguments for decompressive cystocentesis including immediate bladder emptying, pain relief, facilitation of retrohydropropulsion and catheterization, and obtaining uncontaminated urine samples. The arguments against emphasize risks such as iatrogenic bladder trauma, possible rupture, uroabdomen, and potential delays or lack of facilitation in catheter placement. Thus, the main difference is that the pros focus on immediate decompression benefits, while the cons focus on procedural risks and delays. Review: Urethral obstruction in lower urinary tract disease: treatment and controversies. Course evidence: "Decompressive Cystocentesis → very CONTROVERSIAL SUBJECT Arguments FOR - Immediate emptying of the urinary bladder - Relieves bladder pain - Facilitates retrohydropropulsion of obstructive material - Decreases intraluminal pressure to aid passage to urinary…"

7. In managing a patient with acute kidney injury (AKI) who is experiencing vomiting and risk of gastric ulcers, which medication strategy should be applied?

A. Avoid all medications and rely solely on dietary changes

B. Use maropitant or ondansetron to control vomiting and omeprazole or sucralfate to prevent gastric ulcers

C. Administer only intravenous fluids without anti-nausea or acid suppression drugs

D. Use antibiotics to treat vomiting and antacids for ulcers

Answer: (B)

Explicación

The source states that anti-nausea drugs such as maropitant and ondansetron are used to manage vomiting, and gastric acid suppression with omeprazole or sucralfate helps prevent gastric ulcers, making this the appropriate management approach. Review: Medical management of AKI including fluid therapy and supportive care. Course evidence: "- Anti-nausea drugs such as maropitant and ondansetron are used to manage vomiting. - Gastric acid suppression with omeprazole or sucralfate helps prevent gastric ulcers."

A. Presence of hypertension, hematuria, and edema

B. Elevated serum creatinine, oliguria, and proteinuria

C. Leukocyturia, fever, and flank pain

D. The triad of hypoalbuminemia, proteinuria, and hypercholesterolemia

Answer: (D)

Explicación

Nephrotic syndrome is specifically defined by the triad of hypoalbuminemia, proteinuria, and hypercholesterolemia, as stated in the source. The other options describe symptoms or findings not characteristic of nephrotic syndrome. Review: Glomerulonephritis (GN): pathophysiology, diagnosis, and treatment. Course evidence: "Nephrotic syndrome : A clinical syndrome defined by the triad of hypoalbuminemia, proteinuria, and hypercholesterolemia, which is pathognomonic of glomerulonephritis."

9. Which treatment is proven to reduce recurrent episodes of Feline Lower Urinary Tract Disease (FLUTD) by increasing water intake and diluting urine?

A. Feliway diffusers

B. Amitriptyline

C. Canned food

D. Synthetic glycosaminoglycans

Answer: (C)

Explicación

The source states that canned food is the only treatment proven to reduce recurrent FLUTD episodes by increasing water intake and diluting urine. Amitriptyline is effective in chronic cases but not proven to reduce recurrence by this mechanism. Synthetic glycosaminoglycans have unproven efficacy, and Feliway diffusers are used for stress reduction, not directly for urine dilution. Review: Feline Lower Urinary Tract Disease (FLUTD) management and prevention. Course evidence: "Canned food is the only treatment proven to reduce recurrent FLUTD episodes by increasing water intake and diluting urine."
