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 has been taking alprazolam (Xanax) for four years to manage anxiety. The client reports taking 0.5 mg four times a day. Which statement indicates that the client understands the nurse's teaching about discontinuing the medication?

• A. "I can drink alcohol now that I am decreasing my Xanax."?
• B. "I should not take another Xanax pill. Here is what is left of my last prescription."?
• C. "I should take three pills per day next week, then two pills for one week, then one pill for one week."?
• D. "I can expect to be sleepy for several days after stopping the medicine."?

Correct answer: C

Rationale: Explanation: When discontinuing alprazolam (Xanax) after long-term use, it is crucial to taper the dosage gradually to prevent withdrawal symptoms. The correct statement indicates an understanding of this by planning a structured decrease in dosage over time. Choice A is incorrect as drinking alcohol while decreasing Xanax can be dangerous and is not recommended. Choice B is incorrect as abruptly stopping Xanax is not safe and can lead to withdrawal symptoms. Choice D is incorrect as expecting to be sleepy for several days after stopping the medication does not address the need for a gradual tapering process to avoid withdrawal symptoms.

3. The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:

• A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.
• B. have few, if any, side effects.
• C. are used to treat multiple types of cancer.
• D. are cell-cycle-specific agents.

Correct answer: A

Rationale: Alkylating agents, such as nitrogen mustards, are effective chemotherapeutic agents because they cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA. This cross-linking interferes with DNA replication and transcription, leading to cell death. Choice B is incorrect because alkylating agents have numerous side effects, including alopecia, nausea, vomiting, and myelosuppression. Choice C is incorrect because while nitrogen mustards are used to treat multiple types of cancer like chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, their effectiveness is primarily due to DNA cross-linkage. Choice D is incorrect because alkylating agents are non-cell-cycle-specific agents, meaning they can act on cells in any phase of the cell cycle, not just on cells that are actively dividing.

4. 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.

5. An adult who had been abused as a child is discussing the group therapy program. Which statement indicates that the client has gained insight?

• A. "I think I was a lonely child because I could not tell anyone about my abuse."?
• B. "I am now aware of how deep-seated my anger is. Before, I did not realize I was angry."?
• C. "The program has given me the courage to tell my mother how I felt about her role in my hurt."?
• D. "There are so many people just like me, who are just normal people that had bad things happen to them."?

Correct answer: B

Rationale: The correct answer demonstrates insight gained by the client regarding their emotional state. Recognizing deep-seated anger that was previously unrecognized indicates progress in understanding their emotions and the impact of past abuse. Choice A reflects a sense of loneliness due to an inability to share about the abuse, which does not directly address emotional insight. Choice C shows progress in addressing relationships but does not specifically relate to emotional awareness. Choice D acknowledges shared experiences but does not reflect personal emotional growth or insight.
