Atenolol (Tenormin)

ATI class: Beta blocker / Beta1-selective adrenergic blocker

Action

  • ATI/source-folder candidate for Atenolol (Tenormin); verify mechanism against the source table before validation.

Therapeutic use

  • Review under Hypertension medication safety.

Nursing assessment

  • Check apical pulse and blood pressure before administration.
  • Assess dizziness, syncope, fatigue, and signs of worsening heart failure.
  • Review renal function because atenolol is renally cleared.
  • Assess diabetes medications and hypoglycemia awareness because beta blockers can mask tachycardia.

Administration

  • Verify route against the order and source table.

Side effects

  • Verify common side effects against the source table.

Adverse effects

  • Bradycardia
  • Hypotension
  • Heart block
  • Worsening heart failure
  • Bronchospasm in susceptible clients

Interactions

  • Other antihypertensives
  • Digoxin
  • Non-dihydropyridine calcium channel blockers
  • Insulin or oral hypoglycemics
  • NSAIDs may reduce antihypertensive effect

Contraindications

  • See source-specific contraindications and precautions before administration.

Precautions

  • Severe bradycardia, second or third degree heart block without pacing, or cardiogenic shock.
  • Use caution with asthma/COPD, diabetes, older adults, renal impairment, and acute decompensated heart failure.
  • Do not stop abruptly unless directed.

Client teaching

  • Check pulse if instructed and report very slow pulse, fainting, or shortness of breath.
  • Change positions slowly.
  • Do not stop suddenly because rebound angina, hypertension, or dysrhythmia can occur.

Medication outcomes

  • Therapeutic response with no priority adverse effects.

Antidote / rescue

  • No specific antidote is seeded; hold/question unsafe doses and manage toxicity per provider, facility, or poison-control guidance.

NCLEX priority cues

  • Hold and question severe bradycardia or symptomatic hypotension.
  • Wheezing or new shortness of breath after dosing changes priority.
  • Masked hypoglycemia can present without tachycardia.
