2026/ 2027 Update) MOST TESTED
Questions & Answers {Grade A} 100%
Correct (Verified Solutions)
Endoscopy findings for Crohn's Disease - Correct answer cobbles toning (late), skip
lesions, edema, deep linear ulcers, fissures
Is surgery curative for Crohn's and Ulcerative Colitis? - Correct answer Curative for
Ulcerative Colitis. Only used in Crohn's if patient has complications.
Treatment for esophageal varices - Correct answer banding
Respiratory Acidosis - Correct answer pH low
CO2 high
Bicarb may decrease to compensate
Respiratory Alkalosis - Correct answer pH high
CO2 low
,Bicarb may decrease to compensate
Metabolic Acidosis - Correct answer pH low
CO2 decreases to compensate
Bicarb low
Metabolic Alkalosis - Correct answer pH high
CO2 increases to compensate
Bicarb high
Causes of respiratory acidosis - Correct answer aspiration, atelectasis, abdominal
distention, drug overdose, CNS disease, pleural/lung disease, trauma
Tx: spirometry, deep breathing, pain control, ventilation
Causes of respiratory alkalosis - Correct answer hyperventilation, sepsis, asthma, PE,
DKA, infection, stroke, toxins, lung dz
Tx: pain control, CO2 rebreathing
,Causes of metabolic acidosis - Correct answer shock, renal failure, ischemic bowel,
DKA, starvation, EtOH
Tx: volume resuscitation, correct underlying cause
Causes of metabolic alkalosis - Correct answer volume loss, K loss, excessive
diuresis, GI loss
Tx: volume replace (NaCl solution and K replacement)
Acute Renal Failure - Correct answer 50% increase in baseline creatinine.
Deterioration in renal function (GFR) leads to excessive accumulation of nitrogenous
waste products in serum (urea, creatinine) referred to as azotemia. Patients
categorized as prerenal, renal, or postrenal.
Prerenal failure - Correct answer Produced by conditions that decrease renal
perfusion and is most common cause of community acquired acute renal failure (70%)
, Causes of Prerenal failure - Correct answer volume loss (N/V/D, hemorrhage,
diuretics), decreased cardiac output (MI), renal artery/small vessel disease, renal
artery stenosis or embolic disease
Diagnosis of Prerenal failure - Correct answer urine Na <20, 20:1 BUN/Cr ratio, urine
specific gravity >1.020
Treatment of Prerenal failure - Correct answer volume resuscitate
Intrinsic Renal Failure (ATN) - Correct answer caused by severe and prolonged
prerenal etiologies. Nephrotoxins 2nd most common cause (NSAIDs, contrast).
Diagnosis of Intrinsic Renal Failure - Correct answer increased urine sodium >40,
decreased BUN:Cr ratio (<15:1)
Treatment of Intrinsic Renal Failure - Correct answer adequate circulating volume
must be restored first, as hypovolemia potentiates and exacerbates all forms of renal
failure
