INTRODUCTION
The HUN4446 Nutrition and Disease Part 2 Exam is the second course in the sequence at the
University of Florida that focuses on the biochemical and pathophysiological bases of
disease conditions requiring specialized nutrition support and medical nutrition therapy .
This course is designed for upper-level dietetics, nutritional sciences, and pre-health
students who must demonstrate mastery of the pathophysiology, clinical manifestations,
and nutritional management of diseases affecting the gastrointestinal tract, liver, gallbladder,
pancreas, endocrine system, cardiovascular system, and kidneys . The course covers
diseases/disorders of the upper and lower GI tract, liver disease, gallbladder and pancreatic
disorders, diabetes mellitus, hypertension, cardiovascular disease, and kidney disease .
Exams require application of pathophysiological concepts to clinical nutrition case scenarios,
laboratory value interpretation, and evidence-based medical nutrition therapy. This
comprehensive study guide delivers 200 advanced, scenario-based questions modeled
precisely on the HUN4446 curriculum and exam format, with detailed rationales explaining
why each correct answer is right and every distractor fails.
CORE DOMAINS TESTED
• Diseases/Disorders of the Upper GI Tract: Dysphagia, xerostomia, oral mucositis,
thrush, taste alterations, and esophageal disorders
• Diseases/Disorders of the Lower GI Tract: Lactose maldigestion, inflammatory bowel
disease (Crohn's disease and ulcerative colitis), celiac disease, IBS, and short bowel
syndrome
• Liver Disease: Cirrhosis, portal hypertension, esophageal varices, ascites, hepatic
encephalopathy, and malnutrition in liver disease
• Diseases of the Gallbladder and Pancreas: Cholelithiasis, cholecystitis, acute
pancreatitis, chronic pancreatitis, and pancreatic insufficiency
• Diabetes Mellitus: Type 1, type 2, gestational diabetes, acute complications (DKA,
HHS, hypoglycemia), chronic complications, and pharmacologic management
• Hypertension and Cardiovascular Disease: Risk factors, genetic influences, medical
nutrition therapy, and dietary approaches
,2
• Kidney Disease: Acute kidney injury, chronic kidney disease, dialysis, and electrolyte
management
QUESTIONS 1-200
Q1: A patient with Sjögren's syndrome presents with severe dry
mouth and difficulty swallowing dry foods. Which mealtime
intervention is most appropriate to improve oral intake?
A) Provide a high-protein, high-calorie diet with dry toast
B) Offer moist foods with gravies and sauces and encourage sipping
fluids with meals
C) Restrict all fluids during meals to prevent aspiration
D) Administer appetite stimulants before meals
Rationale: The correct answer is B. Sjögren's syndrome causes
autoimmune destruction of salivary and lacrimal glands, leading to
xerostomia (dry mouth) . Moist foods and fluids with meals facilitate
bolus formation and swallowing. Option A is incorrect because dry
foods worsen dysphagia in xerostomia. Option C is incorrect because
fluid restriction would further impair swallowing. Option D is
incorrect because appetite stimulants do not address the mechanical
difficulty of swallowing dry foods .
Q2: A patient undergoing chemotherapy for head and neck cancer
develops painful oral ulcers and reports inability to eat. Which
condition is most consistent with this presentation?
A) Thrush
B) Oral mucositis
C) Xerostomia
D) Dysgeusia
,3
Rationale: The correct answer is B. Oral mucositis presents as painful
ulcers on the lips and tongue, commonly caused by chemotherapy or
radiation, especially for head and neck cancers . Option A is incorrect
because thrush is a fungal infection that appears as white patches.
Option C is incorrect because xerostomia is dry mouth without
ulceration. Option D is incorrect because dysgeusia is altered taste,
not ulceration .
Q3: A patient reports a persistent metallic taste in the mouth
following radiation therapy. Which intervention may help improve
oral intake?
A) Using plastic utensils and containers
B) Drinking hot beverages with meals
C) Increasing high-protein foods at dinner
D) Avoiding cold foods
Rationale: The correct answer is A. Using plastic utensils and
containers may help reduce metallic taste sensations . Option B is
incorrect because cold foods are generally better tolerated than hot
foods with dysgeusia. Option C is incorrect because high-protein
foods are often poorly tolerated with taste alterations and should be
eaten in the morning if at all. Option D is incorrect because cold foods
are usually better tolerated .
Q4: Which microorganism is primarily responsible for dental caries?
A) Candida albicans
B) Streptococcus mutans
C) Lactobacillus acidophilus
D) Porphyromonas gingivalis
Rationale: The correct answer is B. Streptococcus mutans is the
primary cariogenic bacterium responsible for dental caries . Option A
, 4
is incorrect because Candida albicans causes thrush. Option C is
incorrect because Lactobacillus contributes to caries progression but
is not the primary initiator. Option D is incorrect because
Porphyromonas gingivalis is associated with periodontal disease .
Q5: A patient with HIV/AIDS develops white patches on the tongue
and buccal mucosa that can be scraped off. Which treatment is
appropriate?
A) Nystatin
B) Fluconazole
C) Acyclovir
D) Penicillin
Rationale: The correct answer is A. Thrush, caused by Candida
albicans, is treated with nystatin . Option B is incorrect because
fluconazole is used for systemic fungal infections. Option C is incorrect
because acyclovir treats viral infections. Option D is incorrect because
penicillin treats bacterial infections .
Q6: A patient with a history of stroke presents with difficulty
swallowing and is at risk for aspiration. Which intervention is the
priority?
A) Videofluoroscopic swallow study evaluation
B) Immediate placement of a nasogastric tube
C) Clear liquid diet trial
D) Oral nutritional supplements
Rationale: The correct answer is A. A videofluoroscopic swallow study
(modified barium swallow) is the gold standard for evaluating
dysphagia and determining safe food/liquid consistency . Option B is
incorrect because NG tube placement should follow assessment.
Option C is incorrect because clear liquids are often the most
