The 5 Most Common Hormones You’ll See on the 2026 TEAS 7 (And How to Never Miss These Questions)
If you’re preparing for the TEAS 7, here’s the truth most prep guides won’t tell you:
Hormone questions are practically guaranteed.
Every year, the endocrine system shows up on the science section—and students lose easy points because they try to memorize every hormone in the human body.
You don’t need to.
In reality, a small group of hormones appears over and over again on TEAS practice tests and real exams. If you master these five, you’ll be able to solve most hormone-related questions in seconds.
Below are the 5 hormones most likely to appear on the 2026 TEAS 7, plus the quick tricks test-takers use to remember them.
1. Insulin (The Blood Sugar Controller)
If there is one hormone you must know, it’s insulin.
Insulin regulates blood glucose levels by allowing cells to absorb glucose from the bloodstream.
Produced by
- Pancreas
- Specifically beta cells in the islets of Langerhans
What it does
- Lowers blood sugar
- Helps store glucose as glycogen
- Promotes fat storage
What TEAS questions usually ask
Expect questions about:
- Blood sugar regulation
- Diabetes
- Pancreatic function
Example question format:
Which hormone lowers blood glucose levels?
Answer: Insulin
Easy memory trick
Insulin = “In Sugar Lowers”
2. Glucagon (Insulin’s Opposite)
Where insulin lowers blood sugar…
Glucagon raises it.
These two hormones work as a pair, which is exactly why TEAS loves testing them together.
Produced by
- Pancreas
- Alpha cells
What it does
- Raises blood glucose
- Converts glycogen → glucose in the liver
What TEAS questions usually ask
- Which hormone increases blood glucose?
- Hormonal responses during fasting
Example:
During low blood sugar conditions, which hormone is released?
Answer: Glucagon
Easy memory trick
GlucaGON = Glucose GONE from storage
3. Thyroxine (T4) – The Metabolism Hormone
Another TEAS favorite is thyroid hormone, especially thyroxine (T4).
Produced by
- Thyroid gland
What it does
- Regulates metabolism
- Controls energy use
- Influences heart rate and temperature
What TEAS questions usually ask
- Metabolic rate
- Thyroid disorders
- Hormone feedback loops
Example:
Which gland regulates metabolic rate?
Answer: Thyroid gland
Easy memory trick
Thyroid = Thermostat of the body
4. Adrenaline (Epinephrine) – Fight or Flight
This hormone is one of the easiest to recognize because it’s tied to the fight-or-flight response.
Produced by
- Adrenal medulla
What it does
- Increases heart rate
- Raises blood pressure
- Expands airways
- Boosts energy availability
What TEAS questions usually ask
- Stress response
- Sympathetic nervous system
- Adrenal gland function
Example:
Which hormone prepares the body for emergencies?
Answer: Epinephrine
Easy memory trick
Epinephrine = Emergency hormone
5. ADH (Antidiuretic Hormone) – The Water Regulator
Many students overlook ADH, but it appears frequently in TEAS science questions.
Produced by
- Hypothalamus
- Released from posterior pituitary
What it does
- Controls water balance
- Signals kidneys to reabsorb water
- Prevents dehydration
What TEAS questions usually ask
- Kidney function
- Fluid balance
- Urine concentration
Example:
Which hormone reduces urine production?
Answer: ADH
Easy memory trick
ADH = “Anti-Dry Hormone”
The Simple Pattern the TEAS Loves
Here’s something most students don’t realize:
The TEAS exam rarely asks for deep endocrinology knowledge.
Instead, questions usually follow this pattern:
| Hormone | Main Concept Tested |
|---|---|
| Insulin | Blood sugar ↓ |
| Glucagon | Blood sugar ↑ |
| Thyroxine | Metabolism |
| Epinephrine | Stress response |
| ADH | Water balance |
If you understand the function of the hormone, you can answer the question even if the wording changes.
The 10-Second Strategy TEAS Top Scorers Use
When you see a hormone question:
Step 1: Identify the body system
Step 2: Look for the keyword
Step 3: Match hormone → function
Example keyword triggers:
| Keyword | Hormone |
|---|---|
| High blood sugar | Insulin |
| Low blood sugar | Glucagon |
| Metabolism | Thyroxine |
| Stress / emergency | Epinephrine |
| Water balance | ADH |
This shortcut alone can save several minutes on the science section.
Why Hormones Show Up So Often on the TEAS
Hormones are tested heavily because nursing students must understand how body systems communicate and maintain homeostasis.
The endocrine system connects to:
- metabolism
- stress response
- kidney function
- blood sugar regulation
- fluid balance
Which makes it perfect test material for the TEAS.
Want to Master These Before Test Day?
Reading about hormones helps…
But answering real exam-style questions is what actually builds confidence.
If you want to see exactly how these hormones appear on the TEAS, the best step is practicing with full science section simulations.
