D440 HESI Nutrition OA Exam

Case Study: Adolescent with Type 1 Diabetes

An adolescent male, approximately 14 years old, became unresponsive at soccer
practice. Coaches called an ambulance. The client has type 1 diabetes. Friends
said he was complaining of not feeling well earlier that day. He didn't seem to eat
much at lunch but had cheese and nuts before practice. The client is known to
self-administer insulin. There is no history of smoking or alcohol.

Vital Signs & Assessment:

• Height: 65 inches (165 cm)

• Weight: 110 lbs (50 kg)

• BMI: 18.3 kg/m²

• Temperature: 37°C (98.6°F)

• Blood Pressure: 130/83 mmHg

, • Pulse: 97 bpm

• O₂ Saturation: 98%

• Respirations: 18/min

• Blood Glucose: 50 mg/dL (2.8 mmol/L)



1. The nurse recognizes that this client's blood glucose level indicates which
condition?

A. Hyperglycemia
B. Hypoglycemia
C. Normal glucose tolerance
D. Diabetic ketoacidosis

Correct Answer: B

Rationale:
A blood glucose level below 70 mg/dL is indicative of hypoglycemia. The client
consumed noncarbohydrate foods (cheese and nuts) before practice, which would
not support normal blood glucose during physical activity. The elevated blood
pressure (130/83 mmHg) is a compensatory response to low blood glucose, not
hypotension. There is no evidence of hyperglycemia or diabetic ketoacidosis in
this scenario.



2. Which intervention is the priority for the nurse to implement for this client?

A. Administer insulin subcutaneously
B. Provide 15 grams of simple carbohydrates
C. Give 30 grams of fruit juice immediately
D. Monitor electrolytes and fluid balance

,4. Which food selections by a client with celiac disease indicate the nurse's
dietary teaching was successful? Select all that apply.

[ ] A. Green beans
[ ] B. Baked potato
[ ] C. Turkey sandwich on whole-wheat bread
[ ] D. Grilled fish
[ ] E. Whole-wheat cereal
[ ] F. Scrambled eggs
[ ] G. Noodles with marinara sauce
[ ] H. Low-fat milk

Correct Answers: A, B, D, F, H

Rationale:
Clients with celiac disease must follow a gluten-free diet. Green beans (fresh
vegetables), baked potatoes, grilled fish, scrambled eggs, and low-fat milk are all
naturally gluten-free and safe. Turkey sandwiches on whole-wheat bread, whole-
wheat cereal, and noodles contain gluten from wheat and must be avoided. Celiac
clients must avoid gluten found in wheat, oats, and barley.



5. Which nursing actions are appropriate when providing care to a hospitalized
infant diagnosed with failure to thrive (FTT) due to inadequate caloric intake?
Select all that apply.

[ ] A. Consult with social work to determine if the family is living in poverty
[ ] B. Assess the infant's juice consumption
[ ] C. Teach the parents how to properly prepare formula
[ ] D. Assess for sensitivity to cow's milk protein
[ ] E. Screen for cystic fibrosis and celiac disease
[ ] F. Monitor thyroid function studies for hyperthyroidism

,[ ] F. Consume unsaturated fats instead of large amounts of saturated fat
[ ] G. Skip breakfast to reduce caloric intake

Correct Answers: A, B, C, F

Rationale:
Due to the client's elevated lipid labs and blood pressure, it is appropriate to
educate them on both the Mediterranean diet and the DASH diet, as they
complement each other. Physical activity recommendations include 150 minutes
of moderate-intensity exercise per week, or 30 minutes 5 days per week.
Encouraging 150 minutes of exercise 5 days per week (750 minutes total) exceeds
the normal recommendation. The client should avoid large amounts of saturated
fat and instead consume sources of unsaturated fat. Although the client may have
type 2 diabetes risk, carbohydrates such as fruits, vegetables, and whole grains
provide many nutrients and should be consumed in moderation spread
throughout the day. It would not be beneficial to skip breakfast because of the risk
of hypoglycemia.



10. For each food item, click to indicate whether it is generally associated with
the Mediterranean diet, the DASH diet, or both.

Table


Food Item Mediterranean DASH Both
Diet Diet


Fresh fruits and vegetables ✓


Unsalted nuts ✓

,should also educate the client about fat-soluble vitamin supplementation (A, D, E,
K).
