HESI RN NUTRITION EXAM LATEST EXAM 2026 | ALL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALES | ALREADY GRADED A+ | PROFESSOR VERIFIED
Question 1
The Registered Nurse (RN) is caring for a client who was recently diagnosed with Type 2
Diabetes Mellitus (DM). What information is most important for the RN to teach the client
regarding initial lifestyle changes?
A) Increasing the intake of complex carbohydrates to 70% of total calories
B) Transitioning to a strict ketogenic diet to eliminate insulin resistance
C) Incorporating portion-controlled, heart-healthy diet selections
D) Eliminating all snacks between meals to prevent glucose spikes
E) Monitoring blood glucose levels only once per week
Correct Answer: C) Portion-controlled, heart-healthy diet selections
Rationale: For clients newly diagnosed with Type 2 DM, the cornerstone of nutritional
therapy is glycemic control and the prevention of cardiovascular complications. Portion
control helps manage weight and blood glucose levels, while heart-healthy selections (low
saturated fat, high fiber) address the increased risk of atherosclerosis common in diabetic
patients.
Question 2
The RN suspects that a female client with diabetes is altering her self-reported blood glucose
journals to appear more compliant. Which laboratory test should the RN review to determine the
client's actual glycemic control over the past 3 months?
A) Fasting Plasma Glucose (FPG)
B) Oral Glucose Tolerance Test (OGTT)
C) Serum Creatinine
D) Hemoglobin A1C
E) Postprandial Blood Glucose
Correct Answer: D) Hemoglobin A1C
Rationale: The Hemoglobin A1C test measures the average blood glucose level over the
previous 90 to 120 days by evaluating the percentage of glycosylated hemoglobin. Unlike
daily finger sticks or journals, which can be manipulated or represent a single point in
time, the A1C provides a reliable objective measure of long-term compliance and glucose
management.
Question 3
The RN is assessing a client who requires an increase in Vitamin B12 (cobalamin) intake. Which
set of foods should the RN instruct the client to include in their daily diet?
A) Whole grain bread, leafy greens, and citrus fruits
B) Cheese, eggs, and fish
C) Potatoes, corn, and lima beans
D) Apples, bananas, and grapes
E) Vegetable oils and nuts
, 2
Correct Answer: B) Cheese, eggs, and fish
Rationale: Vitamin B12 is naturally found primarily in animal products. Dairy (cheese),
eggs, and seafood (fish) are excellent sources. This is particularly important for clients with
pernicious anemia or those following strict vegan diets who may require supplementation.
Question 4
A home health RN is caring for a client with a Stage III pressure ulcer. To promote tissue repair
and synthesis, the RN recognizes that which food group containing zinc should be added to the
diet?
A) Leafy green vegetables
B) Citrus fruits and berries
C) Meats and shellfish
D) Enriched white breads
E) Root vegetables like carrots
Correct Answer: C) Meats and shellfish
Rationale: Zinc is a critical trace element for DNA synthesis, cell division, and protein
synthesis, all of which are essential for wound healing. Animal proteins, specifically red
meats and shellfish (like oysters), provide the highest bioavailability of zinc for a client
recovering from skin breakdown.
Question 5
An RN in an assisted living community receives four new admissions. Which client should the
RN prioritize for a higher-caloric nutritional plan?
A) A client with controlled hypertension
B) A client with osteoarthritis of the knees
C) A client with bacterial pneumonia
D) A client with mild cognitive impairment
E) A client with a history of kidney stones
Correct Answer: C) A client with bacterial pneumonia
Rationale: Infection and fever increase the body's metabolic rate and demand for energy. A
client with bacterial pneumonia is in a hypermetabolic state and requires extra calories and
protein to support the immune response and prevent the breakdown of lean body mass
(catabolism).
Question 6
An Orthodox Jewish client is admitted to the hospital. Which meal selection is most appropriate
for the RN to provide while respecting the client's religious dietary laws (Kosher)?
A) Pork chops with mashed potatoes
B) Cheeseburger on a bun
C) Lamb chops with mint jelly
D) Shrimp scampi over pasta
, 3
E) Roast beef served with a glass of milk
Correct Answer: C) Lamb chops with mint jelly
Rationale: Kosher laws prohibit the consumption of "unclean" animals (like pork or
shellfish) and the mixing of meat and dairy in the same meal. Lamb is a permitted animal,
and serving it with mint jelly (no dairy) is acceptable. A cheeseburger or beef with milk
violates the rule against mixing meat and milk.
Question 7
The RN is evaluating a client's understanding of a low-sodium diet for hypertension. Which meal
selection by the client indicates that the teaching was effective?
A) Canned chicken noodle soup with crackers
B) Sliced ham and swiss cheese sandwich
C) White rice, steamed vegetables, cottage cheese, and sliced tomatoes
D) Frozen pepperoni pizza and a side salad with ranch
E) Pickled beets and a hot dog
Correct Answer: C) White rice, steamed vegetables, cottage cheese, and sliced tomatoes
Rationale: Fresh vegetables and plain rice are naturally low in sodium. While cottage cheese
has some sodium, it is significantly lower than processed meats (ham, hot dogs) or canned
and frozen convenience foods, which are typically loaded with salt as a preservative.
Question 8
A client with lactose intolerance requires a diet enriched with calcium and Vitamin D to prevent
bone loss. Which food recommendation is best for this client?
A) Low-fat yogurt and skim milk
B) Fortified soy products
C) Hard cheeses like cheddar
D) Whole wheat pasta
E) Lean poultry
Correct Answer: B) Fortified soy products
Rationale: Clients with lactose intolerance cannot digest the sugar in milk, leading to GI
distress. Fortified soy milk and soy products provide a non-dairy alternative that is
supplemented with Calcium and Vitamin D, matching the nutritional profile of cow's milk
without the lactose.
Question 9
A client is experiencing stress incontinence. Which dietary change should the RN recommend to
help manage this condition?
A) Increase intake of spicy peppers
B) Increase intake of artificial sweeteners
C) Avoid alcohol and caffeine
D) Limit intake of plain water to 500 mL per day
