[lracut11]

The nurse notes that on a client's electrocardiogram tracing, there is one P wave for every QRS complex and a delay in the impulse transmission at the AV node. This regular rhythm is identified as:
 
  1. first-degree AV block.
  2. second-degree AV block type I.
  3. second-degree AV block type II.
  4. complete heart block.

Question 2

Prior to hospitalization, a client had been ingesting high doses of oxycodone. The nurse suspects the client is experiencing symptoms of withdrawal when which of the following are assessed? (Select all that apply.)
 
  1. Muscle twitching and spasms
  2. Restlessness
  3. Increased heart rate
  4. Drop in blood pressure
  5. Increase in blood pressure
  6. Irritability

Answer to Question 1

1
First-degree atrioventricular (AV) block occurs when there is a delay in the impulse transmission at the AV node. This delay occurs with every impulse and can be seen on every beat on the recorded rhythm strip. Second-degree and complete heart block have differences with the P wave and the associated QRS complexes.

Answer to Question 2

1, 2, 3, 5, 6
Withdrawal symptoms include myoclonus or muscle twitching and spasms, restlessness, irritability, increased heart rate, and increased blood pressure. A decrease in blood pressure is not a symptom of narcotic medication withdrawal.
