Nursing Elites

1. The client is admitted with chronic obstructive pulmonary disease. Blood gases reveal pH 7.36, CO2 45, O2 84, HCO3 28. The nurse would assess the client to be in:

• A. Uncompensated acidosis
• B. Compensated alkalosis
• C. Compensated respiratory acidosis
• D. Uncompensated metabolic acidosis

Correct answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.

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. During a school screening, a nurse notices small bruises on the anterior and posterior ribs of an 8-year-old Asian child. The nurse should ask the child:

• A. if the family practices coining
• B. who performs coinings
• C. if the child has fallen
• D. how long the child has been abused

Correct answer: A

Rationale: The correct answer is to ask if the family practices coining. In Asian cultures, coining is a traditional practice believed to draw infections from the body. It involves rubbing a heated coin on the chest and torso, which can cause bruising similar to what the nurse noticed on the child's ribs. This question is important to differentiate between cultural practices and potential child abuse. Choices B, C, and D are incorrect because assuming abuse without considering cultural practices can lead to misinterpretation and inappropriate actions. It's crucial for healthcare providers to be culturally sensitive and gather all relevant information before making conclusions.

4. 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.

5. When assessing a client in crisis, what should the nurse prioritize?

• A. Allowing the client to work through independent problem-solving.
• B. Completing an in-depth evaluation of stressors and responses to the situation.
• C. Focusing on immediate stress reduction.
• D. Recommending ongoing therapy.

Correct answer: C

Rationale: When a client is in crisis, the nurse's priority is to focus on immediate stress reduction. Crisis intervention aims to stabilize the client in the present moment by addressing the most pressing issues. Allowing the client to work through independent problem-solving (Choice A) may not be appropriate during a crisis as they might need immediate support. Completing an in-depth evaluation of stressors (Choice B) is important but not the immediate priority during a crisis. Recommending ongoing therapy (Choice D) may be considered later, but the immediate focus should be on reducing the client's stress and stabilizing the situation.
