1. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

2. A client goes to the mental health center for difficulty concentrating, insomnia, and nightmares. The client reports being raped as a child. The nurse should assess the client for further signs of:

• A. generalized anxiety disorder.
• B. schizophrenia.
• C. post-traumatic stress disorder.
• D. bipolar disorder.

Correct answer: C

Rationale: Given the history of childhood sexual abuse and the presenting symptoms of difficulty concentrating, insomnia, and nightmares, the nurse should assess the client for post-traumatic stress disorder (PTSD). Childhood sexual abuse is strongly associated with adult-onset depression and an increased risk for PTSD. Individuals with PTSD may exhibit re-experiencing symptoms such as flashbacks, nightmares, and heightened reactions to trauma triggers. They may also display emotional numbing, avoidance behaviors, and increased arousal symptoms like difficulty sleeping and hypervigilance. Generalized anxiety disorder (Choice A) is characterized by excessive worry and anxiety about various events or activities, not necessarily tied to a specific trauma. Schizophrenia (Choice B) is a severe mental disorder characterized by distortions in thinking, perception, emotions, and behavior, unrelated to the traumatic event described. Bipolar disorder (Choice D) involves mood swings between depressive and manic episodes, and its symptoms differ from those typically seen in PTSD.

3. Support-system enhancement includes all of the following except:

• A. determining the barriers to using support systems.
• B. discussing ways to help others who are concerned.
• C. exploring life problems of the support-team members.
• D. involving spouse, family, and friends in the care and planning.

Correct answer: C

Rationale: Support-system enhancement involves various strategies to strengthen the support system. Determining the barriers to using support systems, discussing ways to help others who are concerned, and involving spouse, family, and friends in the care and planning are all essential aspects of enhancing the support system. However, exploring the life problems of the support-team members is not directly related to enhancing the support system. This approach could potentially invade personal boundaries and may not be necessary for improving the support system, making it the correct answer in this case. Therefore, option C is the correct answer as it does not align with the appropriate methods of support-system enhancement.

4. How does the ANA define the psychiatric nursing role?

• A. a specialized area of nursing practice that employs theories of human behavior as its science and the powerful use of self as its art
• B. assisting the therapist to relieve the symptoms of clients
• C. to solve clients' problems and give them the answers
• D. having a client committed to long-term therapy with the nurse

Correct answer: A

Rationale: The correct answer aligns with the ANA's definition of the psychiatric nursing role. According to the ANA, psychiatric nursing is a specialized area of nursing practice that incorporates theories of human behavior as its foundational science and utilizes the self as its essential art. This definition emphasizes the importance of understanding human behavior and leveraging therapeutic communication and relationships to provide effective care for individuals with mental health concerns. Choices B, C, and D are incorrect because they do not accurately represent the ANA-defined role of psychiatric nursing. Psychiatric nurses primarily focus on delivering holistic care, promoting mental health, and supporting individuals with mental health challenges using evidence-based practices and therapeutic interventions.

5. While the client is receiving quinidine, the nurse should monitor the ECG for:

• A. Peaked P wave
• B. Elevated ST segment
• C. Inverted T wave
• D. Prolonged QT interval

Correct answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.
