How would the nurse categorize the next logical drug choice for this patient? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Standard Text: Select all that apply.
 
  1. As a dopamine-serotonin system stabilizer
  2. As an atypical drug
  3. As a conventional drug
  4. As a third generation drug
  5. As a second generation drug

Question 2

In a person with a sinus rhythm, the primary purpose of the AV node is to
 
  1. pace the heart at 4060 bpm.
  2. delay the impulse from the SA node.
  3. pace the heart at 60100 bpm.

Answer to Question 1

1,2,4
Rationale 1: Dopamine-serotonin system stabilizers were developed due to side effects of previously developed drugs.
Rationale 2: The drug of choice will control both positive and negative symptoms of schizophrenia; therefore, it is an atypical drug.
Rationale 3: Conventional drugs treat only the positive signs of schizophrenia.
Rationale 4: Third generation antipsychotics are used when drugs from a lower generation are ineffective.
Rationale 5: Second class antipsychotics do not have the properties needed by this patient.

Global Rationale: Dopamine-serotonin system stabilizers were developed due to side effects of previously developed drugs. The drug of choice will control both positive and negative symptoms of schizophrenia; therefore, it is an atypical drug. This class of drugs is sometime considered a third generation of antipsychotics. Conventional drugs treat only the positive signs of schizophrenia.

Answer to Question 2

2
Rationale 1: The AV junction does pace the heart at 4060 bpm, but not when the SA node is pacing the heart.
Rationale 2: The AV node delays the impulse as it travels from the atria to the ventricles.
Rationale 3: The AV junction does not pace the heart at 60100 bpm.
Rationale 4: The AV node does not enhance the impulse as it travels from the atria to the ventricles.
Global Rationale: The AV node delays the impulse as it travels from the atria to the ventricles. The AV junction does pace the heart at 4060 bpm, but not when the SA node is pacing the heart.
