A nurse working in an emergency department is assessing a client who is experiencing chest pain that began 6 hr ago. Which of the following findings indicates that the client is having a myocardial Infarction?
Decreased creatine kinase-MB
Decrease in respiratory rate
ST segment depression
Increased troponin I
The Correct Answer is D
Rationale:
A. Decreased creatine kinase-MB: CK-MB is a cardiac enzyme that rises within 4–6 hours of myocardial infarction and peaks around 24 hours. A decrease in CK-MB would not indicate acute myocardial injury and is not a diagnostic marker in this case.
B. Decrease in respiratory rate: A lower respiratory rate is not a typical or reliable indicator of myocardial infarction. Clients experiencing an MI are more likely to show signs of dyspnea, anxiety, or increased respiratory effort due to pain or decreased oxygenation.
C. ST segment depression: ST segment depression may indicate myocardial ischemia or a non-ST elevation myocardial infarction (NSTEMI), but it is less specific than biomarkers like troponin. It may also appear in other conditions such as angina or electrolyte imbalances.
D. Increased troponin I: Troponin I is a highly specific and sensitive cardiac biomarker that rises within 3–6 hours of myocardial injury. An elevated troponin I level 6 hours after the onset of chest pain strongly supports the diagnosis of myocardial infarction.

Correct Answer is ["B","C","D"]
Explanation
Rationale:
- Client has initiated a daily exercise routine: This indicates self-motivation, structured routine, and engagement in positive coping behaviors, all of which are therapeutic goals in managing schizophrenia.
- Client utilizes deep breathing techniques as needed: Use of self-regulation techniques like deep breathing suggests the client is managing anxiety and stress proactively.
- Client has joined a local support group: Participation in social support groups improves social functioning and decreases isolation, a common issue in schizophrenia.
- Client has been reading books about their illness: Demonstrates insight, knowledge-seeking behavior, and a willingness to understand and manage the condition, which aligns with psychoeducation goals.
- Client participates in cognitive-behavioral therapy sessions with their mental health provider: Engagement in CBT is a strong indicator of therapeutic alliance and compliance with structured treatment plans aimed at cognitive restructuring and behavioral management.
Rationale for Incorrect Finding:
- Client reports spending most of their time alone in their apartment: Although some solitude is not unusual, spending most of the time alone may indicate ongoing social withdrawal, a negative symptom of schizophrenia, and a barrier to full community reintegration.
- Client reports drinking 4 to 5 cups of coffee each morning: Excessive caffeine can worsen anxiety, interfere with sleep, and interact with psychiatric medications, so this behavior does not align with optimal treatment outcomes.
Correct Answer is B
Explanation
Rationale:
A. Cheyne-Stokes respirations: This irregular breathing pattern is common in clients nearing end of life due to neurologic decline. It is not a direct indicator of pain and does not necessarily require pain medication unless associated with distress.
B. Restlessness: Restlessness in a palliative care client often signals unrelieved pain, discomfort, or anxiety. It is a nonverbal cue frequently observed in clients unable to communicate pain and should prompt consideration of analgesia.
C. Mottled skin: Mottling is a sign of reduced perfusion and impending death. It reflects circulatory changes but does not directly indicate pain or warrant pain medication unless accompanied by other signs of distress.
D. Constricted pupils: Pupil constriction may result from certain medications (e.g., opioids) or brainstem pressure but is not a reliable sign of pain. It does not, by itself, indicate a need for analgesic intervention.
