ABSITE Advanced Clinical & Surgical Nutrition
Practice Exam 2026 | High-Yield Questions with
Verified Answers | Surgery Board Review
The ABSITE Advanced Clinical and Surgical Nutrition Practice Exam – 2026 Edition is a
high-yield study resource designed for general surgery residents preparing for the ABSITE.
This practice exam focuses specifically on clinical and surgical nutrition, one of the most
frequently tested and high-scoring domains on the ABSITE.
This resource includes exam-style questions with verified correct answers, covering essential
topics such as enteral and parenteral nutrition, metabolic response to trauma, perioperative
nutritional assessment, micronutrient deficiencies, malnutrition, and nutrition in critical
illness. Content is aligned with ABSITE expectations and surgical board standards, making it
ideal for targeted review and rapid knowledge reinforcement.

Death from postoperative renal failure is most commonly due to?
a.) Myocardial infarction
,b.) Bleeding
c.) Sepsis
d.) Liver failure - CORRECT ANSWER- (c)
In hyperacute rejection of a recently transplanted kidney, the event associated with
organ loss is:
a.) Direct antibody effect on interstitial stromal cells.
b.) Ischemia.
c.) Antigen antibody complexes obstructing the proximal convoluted tubule.
d.) Direct antibody effect on the glomerulus.
e.) Destruction of the Loop of Henle. - CORRECT ANSWER- (b)
Preformed anti-donor antibodies that then target the surface of vascular endothelial
cells and graft parenchymal cells. (occurs with minutes to hours and treatment is
removal of organ) Circulating complement is fixed in the vascular compartment
and the environment changes from anticoagulant to procoagulant and vascular
thrombosis occurs. Death of the organ is secondary to ischemia.
Which of the following statements about fetal circulation are true?
a.) Approximately 25% of all blood volume is passed through the fetal lung; the
remainder is shunted into the left ventricle.
b.) The umbilical arteries carry oxygenated blood from the placenta to the fetus.
c.) Failure of pulmonary vascular resistance to fall immediately following birth
will result in neonatal respiratory failure.
,d.) The ductus arteriosus closes anatomically in the first hour of life. - CORRECT
ANSWER- (c)
Which nutrient is poorly absorbed in achlorhydria?
a.) Vitamin D
b.) Vitamin B12
c.) Bile salts
d.) Proteins
e.) Fats - CORRECT ANSWER- (b)
Vitamin B12
Hypophosphatemia has been associated with all of the following EXCEPT:
a.) impaired diaphragmatic contractility
b.) treated diabetic ketoacidosis
c.) malabsorption coupled with carbohydrate refeeding
d.) chronic alcoholism
e.) respiratory muscle hyperresponsiveness - CORRECT ANSWER- (e)
It is seen in patients with chronic alcoholism, diabetic ketoacidosis, sepsis, and
severe malnutrition after carbohydrate refeeding. It can also be seen in surgical
, patients who are not receiving enough phosphate repletion from parenteral
nutrition. Hypophosphatemia causes muscle weakness, and probably affects the
diaphragm more than other muscles, therefore leading to respiratory failure.
Studies have shown lower contractility of the diaphragm
Phosphorus deficiency may lead to insulin resistance as well
What is the main nutrient for colonocytes?
a.) Glutamine
b.) Alanine
c.) Short chain fatty acids
d.) Glucose - CORRECT ANSWER- (c)
Short chain fatty acids
(Note: the primary fuel source though for enterocytes is glutamine)
What chemotherapy agent leads to pulmonary fibrosis?
a.) Doxorubicin
b.) Methotrexate
c.) Bleomycin
d.) Vincristine
e.) Cyclophosphamide - CORRECT ANSWER- (c)
