A client has been prescribed propranolol (Inderal) for a dysrhythmia. Which side effects noted in the nursing assessment might be related to propranolol (Inderal)?(Select all that apply.)
 
  1. Bradycardia
  2. Tachycardia
  3. Hypertension
  4. Hypotension
  5. Hyperglycemia

Question 2

The client asks the nurse how most medications for dysrhythmias work. What is the best response by the nurse?
 
  1. Blocking potassium, sodium, or calcium ion channels is the primary way to prevent or terminate dysrhythmias.
  2. Most medications for dysrhythmias shorten the refractory period.
  3. These medications will lower your blood pressure, which will change the rhythm of your heart.
  4. The mechanism of these drugs is unknown.

Answer to Question 1

1, 4

Rationale 1: Blockade of beta receptors in the heart can result in bradycardia, and hypotension can cause dizziness and possible fainting.
Rationale 2:Tachycardia is incorrect because beta blockers slow heart rate and can cause bradycardia.
Rationale 3:Hypertension is incorrect because beta blockers lower blood pressure and can cause hypotension.
Rationale 4: Blockade of beta receptors in the heart can result in bradycardia, and hypotension can cause dizziness and possible fainting.
Rationale 5: Hyperglycemia is not a known side effect of beta blockers.

Global Rationale: Blockade of beta receptors in the heart can result in bradycardia, and hypotension can cause dizziness and possible fainting.

Answer to Question 2

1

Rationale 1: Blocking potassium, sodium, or calcium ion channels is the primary pharmacologic strategy used to prevent or terminate dysrhythmias.
Rationale 2: Some drugs for dysrhythmias will increase the refractory period.
Rationale 3:Many of antidysrhythmic medications block sodium, potassium,and calcium ion channelsthat will also affect the blood pressure.
Rationale 4:The main way they work is to block potassium, sodium, or calcium ion channels.

Global Rationale: Most antidysrhythmic drugs act by interfering with the cardiac action potential of the potassium, sodium, or calcium ion channels to prevent or terminate dysrhythmias.
