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. While admitting a client to an acute-care psychiatric unit, the nurse asks about substance abuse based on:

• A. psychiatric disorders' higher prevalence in addicted populations
• B. individuals with psychiatric disorders' increased susceptibility to substance abuse
• C. the importance of detecting and diagnosing substance disorders in acute-care psychiatric settings
• D. the significant impact of undetected substance problems on the treatment of psychiatric disorders

Correct answer: B

Rationale: The correct answer is 'individuals with psychiatric disorders' increased susceptibility to substance abuse.' It is crucial to inquire about substance abuse during admission to an acute-care psychiatric unit because individuals with psychiatric disorders are more prone to experiencing substance abuse issues. Addressing substance abuse is vital for effective treatment and to prevent relapse in psychiatric disorders. Option A is incorrect as it focuses on the prevalence of psychiatric illness in addicted populations rather than the relationship between psychiatric disorders and substance abuse. Option C is incorrect as it exaggerates the ease of detecting and diagnosing substance disorders in acute-care psychiatric settings. Option D is incorrect as undetected substance problems can indeed significantly impact the treatment of psychiatric disorders, but the main reason for inquiring about substance abuse is the increased susceptibility of individuals with psychiatric disorders to such issues.

3. The physician has ordered sodium warfarin (Coumadin) for the client with thrombophlebitis. The order should be entered to administer the medication at:

• A. 900
• B. 1200
• C. 1700
• D. 2100

Correct answer: C

Rationale: Sodium warfarin is typically administered in the late afternoon, around 1700 hours. This timing allows for accurate bleeding times to be drawn in the morning. Administering it at 0900 (choice A) would not align with this schedule and may affect the monitoring of bleeding times. Choice B (1200) is midday, which is not the recommended time for sodium warfarin administration. Choice D (2100) is in the evening, which is also not ideal. Therefore, the correct time for administering sodium warfarin is 1700 (choice C).

4. In the emergency room, a nurse is responsible for triaging four clients injured in a motor vehicle accident. Which of the following clients should receive priority in care?

• A. A 10-year-old with lacerations on the face
• B. A 15-year-old with sternal bruises
• C. A 34-year-old with a fractured femur
• D. A 50-year-old with a dislocated elbow

Correct answer: B

Rationale: The 15-year-old with sternal bruises should receive priority in care as this client might be experiencing airway and oxygenation problems. Airway issues take precedence in triage. The 10-year-old with lacerations on the face, although looking bad, is not in immediate distress. The 34-year-old with a fractured femur should be immobilized but can be seen after the client with sternal bruising. The 50-year-old with a dislocated elbow can also be seen later as dislocated elbows are not life-threatening compared to potential airway compromise.

5. A new nursing graduate indicates in charting entries that he is a licensed practical nurse, although he has not yet received the results of the licensing exam. The graduate's action can result in what type of charge?

• A. Fraud
• B. Tort
• C. Malpractice
• D. Negligence

Correct answer: A

Rationale: The correct answer is 'Fraud.' Identifying oneself as a nurse without a license defrauds the public and can lead to prosecution. A tort is a wrongful act in breach of a legal duty imposed by law; malpractice is the failure to act appropriately as a nurse or acting in a way that harm comes to the client; and negligence is failing to perform care. In this scenario, the key issue is the misrepresentation of licensure status, which constitutes fraud. Therefore, choices B, C, and D are incorrect.
