1. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

A. CPK-BB
B. CPK-MM
C. CPK-MB
D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

2. The nurse is caring for a client awaiting test results on a biopsy. The client is unconscious, and the physician informs the client's spouse that the biopsy came back positive for cancer. The spouse asks the nurse if they will not share this news with the client because they would prefer the client be unaware of the diagnosis. Which of the following responses is most appropriate?

A. "I will have a psychiatrist confirm whether the news will cause negative effects, and if so, I will comply with your request."?
B. "For ethical reasons, I am unable to withhold this information from the client."?
C. "You do not have the option to sign paperwork stating you are accepting the risk of not sharing this with the client."?
D. "You must have a durable power of attorney for healthcare advanced directive in place before I can consider this request."?

Correct answer: B

Rationale: The correct response is, "For ethical reasons, I am unable to withhold this information from the client."? The ethical principle of veracity requires that the nurse is truthful with the client and does not withhold information even if it is requested by the family. Choice A is incorrect because seeking a psychiatrist's confirmation is not necessary to uphold the ethical principle of truth-telling. Choice C is incorrect as implying that signing paperwork overrides the nurse's ethical obligation to be honest with the client is inappropriate. Choice D is also incorrect as a durable power of attorney is not relevant in this situation where the spouse is asking the nurse to withhold information.

3. When planning play activities for a hospitalized school-age child, a nurse uses Erikson's theory of psychosocial development to select an appropriate activity. The nurse selects an activity that will assist the child in developing which developmental goal?

A. A sense of industry
B. Autonomy
C. A sense of trust
D. Initiative

Correct answer: C

Rationale: The correct answer is 'A sense of industry.' According to Erikson, the central task of the school-age years is the development of a sense of industry. During this stage, children engage in activities like schoolwork, crafts, chores, hobbies, and sports to develop a sense of competence and productivity. The development of trust is the primary task of infancy, autonomy is the task of toddlerhood, and initiative is the task of the preschool years. Therefore, in this scenario, focusing on fostering a sense of industry aligns with the developmental goals of a school-age child.

4. The LPN is caring for a 32-year-old female client who is 8 hours post-op after a tonsillectomy. Which of these actions would be appropriate for the nurse to take?

A. Inform the client that ear pain may occur and is normal.
B. Provide ice water and a straw to promote easy fluid consumption.
C. Provide hot tea to soothe the throat.
D. Monitor vitals every 15 minutes.

Correct answer: A

Rationale: The appropriate action for the nurse to take is to inform the client that ear pain may occur and is normal after a tonsillectomy. Referred pain in the ear is common due to related nerve pathways. It is essential to educate the client about this to alleviate concerns. Providing ice water and a straw is not recommended as they may irritate the throat and disturb the healing process. Hot beverages like tea should also be avoided for the same reason. While monitoring vitals every 15 minutes is crucial in the immediate postoperative period for early identification of any complications, it is not the most appropriate action in this scenario where addressing the client's concerns and providing education is key.

5. A Hispanic client brings her father to the clinic because he is becoming more forgetful. He is diagnosed with Alzheimer's disease. The woman tells the nurse that she wants to try ginkgo biloba for her father before using prescription medications. Which of the following is an appropriate response by the nurse?

A. "It is wiser to start with a prescription."?
B. "That herb may not be effective for your father."?
C. "You can't expect an herb to cure Alzheimer's."?
D. "I will let the physician know of your wishes."?

Correct answer: D

Rationale: The appropriate response is to acknowledge the client's wishes and communicate them to the physician for consideration. It is important to be culturally sensitive and respect the client's preferences. Ginkgo biloba has shown some benefits in treating dementia, so it is essential to involve the healthcare provider in the decision-making process. Choices A, B, and C are dismissive and fail to consider the client's perspective and cultural beliefs. It is crucial for healthcare professionals to engage in open communication and collaboration with clients to provide patient-centered care.
