Nursing Elites

1. Incidences of child abuse appear to be higher in the African-American community and might be explained by:

• A. the increased number of single-parent households in African-American communities
• B. more single-parent households in African-American communities
• C. stricter child-rearing practices in African-American households
• D. a higher occurrence of rage in African Americans

Correct answer: B

Rationale: Child abuse is often associated with lower socioeconomic status and single-parent households due to increased stress and fewer support systems. Choice A is correct as single-parent households can face more challenges leading to a higher risk of child abuse. Choice B is the correct answer as it aligns with the risk factors associated with child abuse. Choice C is incorrect because there is no direct correlation between stricter child-rearing practices and child abuse rates. Choice D is incorrect because attributing child abuse to a higher occurrence of rage in African Americans is a stereotype and lacks evidence.

2. 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.

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. The nurse is caring for a client scheduled for a surgical repair of a sacular abdominal aortic aneurysm. Which assessment is most crucial during the preoperative period?

• A. Assessment of the client's level of anxiety
• B. Evaluation of the client's exercise tolerance
• C. Identification of peripheral pulses
• D. Assessment of bowel sounds and activity

Correct answer: C

Rationale: The most crucial assessment during the preoperative period for a client scheduled for surgical repair of a sacular abdominal aortic aneurysm is the identification of peripheral pulses. This is essential because during surgery, the aorta will be clamped, potentially affecting blood circulation to the kidneys and lower extremities. Monitoring peripheral pulses helps assess circulation to the lower extremities, ensuring adequate perfusion. While assessing the client's anxiety level (choice A) is important, it is not as critical as monitoring peripheral pulses in this case. Evaluating exercise tolerance (choice B) is not typically recommended preoperatively for this specific condition. Assessing bowel sounds and activity (choice D) is also relevant but takes a lower priority compared to identifying peripheral pulses in this scenario.

5. A 10-month-old child is brought to the Emergency Department because he is difficult to awaken. The nurse notes bruises on both upper arms. These findings are most consistent with

• A. wearing clothing that is too small for the child
• B. the child being shaken
• C. falling while learning to walk
• D. parents trying to awaken the child

Correct answer: B

Rationale: The correct answer is 'the child being shaken.' Children who are shaken are frequently grasped by both upper arms, leading to bruises in that area. The presentation of a difficult-to-awaken child with bruises on the upper arms is highly concerning for non-accidental trauma, such as abusive shaking. Symptoms of brain injury associated with shaking include a decreased level of consciousness. Choices A, C, and D are less likely because the combination of a child being difficult to awaken and bruises on both upper arms is highly suggestive of non-accidental trauma rather than benign causes like ill-fitting clothing, falling while learning to walk, or parents trying to awaken the child.
