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. In the United States, several definitions of death are currently being used. The definition that uses apnea testing and pupillary responses to light is termed:

• A. whole brain death.
• B. heart-lung death.
• C. circulatory death.
• D. higher brain death.

Correct answer: A

Rationale: The correct answer is 'whole brain death.' Most protocols for determining whole brain death require two separate clinical examinations, including the induction of painful stimuli, pupillary responses to light, oculovestibular testing, and apnea testing. This comprehensive approach ensures that all functions of the brain, including the brainstem, are evaluated to confirm the absence of brain function. Choices B and D are incorrect as they do not reflect the specific tests required for determining whole brain death. Choice C, 'circulatory death,' does not involve the evaluation of brain function and is not a current definition of death in the United States.

3. While walking in the hallway of an acute care unit of the hospital, the nurse overhears the change of shift report. What should the nurse do?

• A. Make the charge nurse on the unit aware of the situation so that they can take the necessary steps to maintain the confidentiality of the information being reported.
• B. Disregard the information because it changes quickly on the acute care unit and is outdated within 2-3 hours anyway.
• C. Return to their own unit and not disclose that confidential information has been overheard.
• D. Ignore the situation.

Correct answer: A

Rationale: To protect the confidentiality of the information being reported, the nurse should make the charge nurse on the unit aware of the situation. This allows the charge nurse to take necessary steps to maintain confidentiality and ensure that the information is communicated in an appropriate and private manner. Disclosing the situation to the charge nurse is essential to address any breaches in confidentiality and uphold professional standards of privacy and ethics. Disregarding the information, returning to their own unit without disclosure, or ignoring the situation altogether would not address the breach of confidentiality and could lead to further issues regarding patient privacy and trust.

4. A client recently lost a child due to poisoning. The client tells the nurse, 'I don’t want to make any new friends right now.' This is an example of which of the following indicators of stress?

• A. emotional indicator
• B. spiritual indicator
• C. sociocultural indicator
• D. intellectual indicator

Correct answer: C

Rationale: The correct answer is C, 'sociocultural indicator.' This client's reluctance to make new friends after experiencing a traumatic event like losing a child is a clear sign of sociocultural stress. Sociocultural stress can impact a person's social interactions, relationships, and cultural practices. Choices A, B, and D are incorrect. Choice A, 'emotional indicator,' would focus on emotional responses directly related to stress. Choice B, 'spiritual indicator,' refers to stress related to spiritual beliefs, practices, or values, which is not evident in this scenario. Choice D, 'intellectual indicator,' is not a recognized category of stress indicators in this context.

5. James returns home from school angry and upset because his teacher gave him a low grade on an assignment. After returning home from school, he kicks the dog. This coping mechanism is known as:

• A. denial
• B. suppression
• C. displacement
• D. fantasy

Correct answer: C

Rationale: The correct answer is 'displacement.' Displacement is a defense mechanism where emotions or impulses are transferred from their original source to a substitute target. In this scenario, James is displacing his anger from his teacher onto the dog. Choice A, 'denial,' involves refusing to acknowledge an unpleasant reality. Choice B, 'suppression,' is the conscious effort to push unwanted thoughts out of awareness. Choice D, 'fantasy,' refers to imagining scenarios that fulfill one's desires but are not based in reality.
