What to do first
1. Check apical pulse and blood pressure before giving.
2. Ask about dizziness, syncope, shortness of breath, wheezing, and fatigue.
3. For patients with diabetes, remember beta blockers can mask tachycardia from hypoglycemia.
Beta Blockers NCLEX Priority Sheet
Beta blocker questions test pulse and blood pressure before administration, bradycardia, hypotension, bronchospasm risk, masking hypoglycemia, and not stopping abruptly.
Study aid - not medical advice. Not a clinical decision tool. For NCLEX pharmacology review only.
Hold If
Notify the provider and follow protocol for HR <60 bpm, symptomatic bradycardia, hypotension, new heart block, wheezing/bronchospasm, acute heart failure worsening, or severe dizziness.
Do not stop abruptly without provider guidance because rebound tachycardia, hypertension, or angina can occur.
Labs to Watch
No single drug level is typical for NCLEX beta blocker questions. Watch HR, BP, ECG rhythm when relevant, glucose in patients with diabetes, and renal/hepatic function depending on the specific medication.
Assess symptoms, not just numbers.

NCLEX Review Notes
Suffix Rule
NCLEX memory rule: many beta blockers end in -lol, such as metoprolol, atenolol, propranolol, and carvedilol.
Priority check: pulse and BP before administration.
Priority check: pulse and BP before administration.
NCLEX Trap
Trap: a diabetic patient says, 'I will know my blood sugar is low because my heart will race.'
Correction: beta blockers can mask tachycardia. Teach other hypoglycemia signs such as sweating, hunger, confusion, shakiness, and glucose checks.

Related Pattern
Nonselective beta blockers: higher bronchospasm concern in asthma/COPD contexts.
Cardioselective agents: still require monitoring and provider judgment; NCLEX uses wheezing as a safety clue.

Mini Quiz
Question: A patient scheduled for metoprolol has HR 52, BP 88/54, and dizziness. What should the nurse do?
Answer: hold per protocol, assess symptoms, and notify the provider.
Answer: hold per protocol, assess symptoms, and notify the provider.
