Correct Answer: A

Rationale: A potassium level of 2.9 mEq/dl is critically low, indicating hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Prompt notification to the healthcare provider is essential for immediate intervention. Choice B, a blood pressure of 110/70 mmHg, is within the normal range. Choice C, a white blood cell count of 10,000 mm³, is also within normal limits and is not a concerning finding in this context. Choice D, a body mass index of 21, may indicate being underweight but is not as urgent as addressing the critically low potassium level.

Correct Answer: A

Rationale: The correct answer is A because the client is projecting their own aggressive tendencies onto the psychiatric aide by suggesting hitting the wall instead of the aide. This statement reflects projection, a defense mechanism where one attributes their unacceptable feelings or impulses to others. Choice B reflects externalization rather than projection, Choice C reflects rationalization, and Choice D reflects denial.

Correct Answer: B

Rationale: The correct answer is B: "Remain alcohol-free for 12 hours prior to the first dose." It is essential for the client to understand the importance of abstaining from alcohol for at least 12 hours before starting disulfiram to prevent potential adverse reactions. Choice A is incorrect because disulfiram is specifically used to deter alcohol consumption, not heroin or cocaine use. Choice C is not directly related to the initiation of disulfiram therapy and attending AA meetings is not a requirement for taking disulfiram. Choice D is irrelevant and unnecessary for the initiation of disulfiram therapy.

Correct Answer: B

Rationale: During admission to a psychiatric unit, it is crucial for the registered nurse to remain calm and use a matter-of-fact approach when addressing a client who is extremely anxious. By staying composed and adopting a matter-of-fact demeanor, the nurse can help establish trust and promote a sense of calm in the client. This approach can also convey a sense of reassurance and stability, which can be beneficial in managing the client's anxiety. Assisting the client in developing alternative coping skills (Choice A) may be important in the long term but is not the most immediate priority during the admission process. Asking the client why she is anxious (Choice C) may not be helpful at this moment as the client may not be able to articulate the specific reasons due to her heightened anxiety. Administering a PRN sedative (Choice D) should not be the initial intervention as it does not address the underlying cause of the anxiety and should be considered only if other non-pharmacological interventions are ineffective.

Correct Answer: C

Rationale: Resilience is the ability to adapt and cope with adverse situations. In this case, Christopher's positive outlook, love for school, and good academic performance despite experiencing neglect demonstrate resilience. Choice A, 'Temperament,' refers to an individual's natural behavioral style and would not fully explain Christopher's response. Genetic factors (Choice B) are not directly related to his ability to cope with neglect. Choice D, 'Paradoxical effects of neglect,' does not fit the situation as Christopher's positive response is more indicative of resilience than paradoxical effects.
