Beta-Adrenergic Blockers Flashcards
1
Q
Medications
A
“-olol”
- Atenolol
- Metoprolol
- Propranolol
- Nadolol
2
Q
Actions
A
- Block the stimulatory effects of the SNS
- Block beta-adrenergic receptors in the heart and kidneys, decreases the influence of the SNS on these tissues; decreases CO and release of renin
3
Q
Indication
A
-Teats stable angina pectoris and HTN, prevent reinfarction in MI patients; treats stable CHF
4
Q
Contraindications
A
- Bradycardia
- Heart block
- Cardiogenic shock
- Asthma or COPD
- Pregnancy/lactation
5
Q
Caution
A
- DM
- PVD
- Thyrotoxicosis
6
Q
Adverse effects
A
- Related to their blockage of the SNS
- CNS: dizziness, fatigue, emotional depression
- GI: N/V, colitis
- CV: CHF, decreased CO, and arrhythmias
- Respiratory: bronchospasm, dyspnea, and cough
7
Q
Drug-Drug interactions
A
- Clonidine
- NSAIDs
8
Q
Assessment
A
- History and physical exam
- Assess level of orientation and sensory fx, monitor cardiopulmonary status, including pulse, BP, and RR
- Monitor electrolyte levels
9
Q
Nursing diagnoses
A
- Decreased CO r/t CV effects
- Ineffective tissue perfusion r/t CV effects
- Risk for injury r/t CNS effects
- Risk for activity intolerance r/t suppression of SNS
- Deficient knowledge regarding drug therapy
10
Q
Implementation
A
- Do not stop abruptly, taper gradually over two weeks
- Continuously monitor in a patient receiving an IV form
- Monitor BP, pulse, rhythm, and CO
- Provide pt teaching
11
Q
Evaluation
A
- Evaluation patient response to the drug (alleviation of signs and symptoms of heart failure)
- Monitor for adverse effects
- Evaluate the compliance with the regimen
- Evaluate the effectiveness of the teaching plan
