The client is receiving digoxin (Lanoxin) for a dysrhythmia. Why does the nurse expect medication levels in the blood to be monitored closely?
 
  1. Digoxin causes ventricular dysrhythmias.
  2. Excessive levels can produce serious dysrhythmias.
  3. Subtherapeutic levels are fatal.
  4. Interactions with other medications are common.

Question 2

The client has been started on propranolol (Inderal). What finding does the nurse expect?
 
  1. Increased respiratory rate
  2. Lowered heart rate
  3. Higher oxygen saturation
  4. Stabilized blood pressure

Answer to Question 1

2

Rationale 1: Digoxin (Lanoxin) is used for atrial dysrhythmias.
Rationale 2: Excessive levels can produce serious dysrhythmias, since the action of the drug is to decrease the automaticity of the SA node and slow the conduction through the AV node.
Rationale 3: Subtherapeutic levels can cause the atrial dysrhythmia to continue, which can produce symptoms, but might not be lifethreatening or fatal.
Rationale 4: Interactions with other medications are common, but not monitored by drug levels.

Global Rationale: Excessive levels can produce serious dysrhythmias, since the action of the drug is to decrease the automaticity of the SA node and slow the conduction through the AV node. Digoxin (Lanoxin) is used for atrial dysrhythmias. Subtherapeutic levels can cause the atrial dysrhythmia to continue, which can produce symptoms, but might not be lifethreatening or fatal. Interactions with other medications are common, but not monitored by drug levels.

Answer to Question 2

2

Rationale 1:Increased respiratory rate is incorrect because propranolol reduces heart rate, slows conduction velocity, and lowers blood pressure.
Rationale 2: Propranolol reduces heart rate, slows conduction velocity, and lowers blood pressure.
Rationale 3:Higher oxygen saturation is incorrect because propranolol reduces heart rate, slows conduction velocity, and lowers blood pressure.
Rationale 4:Stabilizedblood pressure is incorrect because propranolol reduces heart rate, slows conduction velocity, and lowers blood pressure.

Global Rationale: Propranolol reduces heart rate, slows conduction velocity, and lowers blood pressure. The drug has no effect on respiratory rate and oxygen saturation.The drug decreases blood pressure and does not stabilizeit.
