📒 The 1-minute cheat sheet
📌 Mech
↑ insulin, ↓ glucagon
Slows gastric emptying
ex: semaglutide, liraglutide
🎓 Teach
SubQ injection, rotate sites
↓ appetite → weight loss
N/V common, take w/ food
🚩 Report
Pancreatitis → severe abd pain
Thyroid C-cell tumor risk
📌 Avoid
MEN-2, medullary thyroid ca
Low hypoglycemia risk alone
📚 GLP-1 Agonists — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
GLP-1 receptor agonists (semaglutide, liraglutide, dulaglutide, exenatide) are incretin mimetics used for type 2 diabetes and weight loss. They lower glucose by stimulating insulin release, suppressing glucagon, and slowing gastric emptying, which also reduces appetite. Most are subcutaneous injections (some weekly, some daily) and carry a low intrinsic risk of hypoglycemia when used alone.
Promote weight loss and have a low risk of hypoglycemia when used alone (risk rises if combined with insulin or sulfonylureas).
Most common side effects are GI: nausea, vomiting, diarrhea, which often improve over time.
Carry a boxed warning for thyroid C-cell tumors (medullary thyroid carcinoma) seen in animal studies.
Pancreatitis is a serious risk; delayed gastric emptying can affect absorption of oral drugs and increase aspiration risk under anesthesia.
✅
Nursing priorities
What to do, in order
Teach proper subcutaneous injection technique, site rotation, and the specific dosing schedule (daily vs weekly).
Monitor for GI side effects and advise eating smaller, slower meals to reduce nausea.
Assess for signs of pancreatitis (severe persistent abdominal pain radiating to the back).
Review concurrent insulin or sulfonylurea use because hypoglycemia risk increases with these combinations.
🚩
Red flags — report now
Escalate immediately
Severe, persistent abdominal pain radiating to the back — possible pancreatitis; hold drug and report immediately.
Neck mass, hoarseness, dysphagia, or persistent hoarse cough — possible thyroid tumor; report now.
Never use in patients with a personal or family history of medullary thyroid carcinoma or MEN 2.

Labs & values
Numbers to know
HbA1c goal generally <7%
Fasting blood glucose 70-99 mg/dL
Monitor lipase/amylase if pancreatitis suspected (lipase normal ~0-160 U/L)
🗣️
Patient teaching
What patients must know
Inject subcutaneously in the abdomen, thigh, or upper arm and rotate sites.
Take exactly on schedule; if a weekly dose is missed, follow the package instructions on timing.
Eat smaller meals and stop when full to reduce nausea and vomiting.
Report severe stomach pain, a neck lump, or trouble swallowing right away.
Tell anesthesia/surgical teams you take a GLP-1 agonist because of delayed stomach emptying and aspiration risk.
❓ GLP-1 Agonists: NCLEX FAQs
What are the priority nursing interventions for GLP-1 Agonists?
Teach proper subcutaneous injection technique, site rotation, and the specific dosing schedule (daily vs weekly). Monitor for GI side effects and advise eating smaller, slower meals to reduce nausea. Assess for signs of pancreatitis (severe persistent abdominal pain radiating to the back). Review concurrent insulin or sulfonylurea use because hypoglycemia risk increases with these combinations.
What are the warning signs of GLP-1 Agonists a nurse must report?
Severe, persistent abdominal pain radiating to the back — possible pancreatitis; hold drug and report immediately. Neck mass, hoarseness, dysphagia, or persistent hoarse cough — possible thyroid tumor; report now. Never use in patients with a personal or family history of medullary thyroid carcinoma or MEN 2.
What do I need to know about GLP-1 Agonists for the NCLEX?
Mechanism: enhance glucose-dependent insulin secretion, suppress glucagon, slow gastric emptying, and increase satiety. Promote weight loss and have a low risk of hypoglycemia when used alone (risk rises if combined with insulin or sulfonylureas). Most common side effects are GI: nausea, vomiting, diarrhea, which often improve over time. Carry a boxed warning for thyroid C-cell tumors (medullary thyroid carcinoma) seen in animal studies.
What patient teaching is important for GLP-1 Agonists?
Inject subcutaneously in the abdomen, thigh, or upper arm and rotate sites. Take exactly on schedule; if a weekly dose is missed, follow the package instructions on timing. Eat smaller meals and stop when full to reduce nausea and vomiting. Report severe stomach pain, a neck lump, or trouble swallowing right away.
