A nurse in a community mental health clinic is assessing a client who began taking lithium carbonate 5 days ago. The client reports fine hand tremors and has a current lithium level of 1.2 mEq/L. Which of the following actions should the nurse take?

A. Naltrexone:
Naltrexone is an opioid receptor antagonist. It blocks the effects of opioids and alcohol in the brain. It's often used as part of a long-term treatment plan to prevent relapse in individuals who have already stopped drinking and are trying to maintain sobriety. Naltrexone does not directly manage acute alcohol withdrawal symptoms. Instead, it helps individuals reduce or quit drinking over the long term by reducing the pleasure associated with alcohol consumption.

B. Disulfiram:
Disulfiram is an aversion therapy medication used as a deterrent to drinking. When someone taking disulfiram consumes alcohol, it causes unpleasant physical reactions, such as nausea, flushing, and palpitations. This discourages individuals from drinking while they are on the medication. Disulfiram is not used to manage acute withdrawal symptoms but rather serves as a deterrent to drinking for individuals who are trying to maintain sobriety.

C. Lorazepam:
Lorazepam is a benzodiazepine medication that acts as a central nervous system depressant. It is commonly used to manage acute alcohol withdrawal symptoms. Benzodiazepines like lorazepam help to reduce anxiety, agitation, and the risk of seizures associated with alcohol withdrawal. They are typically used in a controlled manner to provide relief during the acute phase of withdrawal.

D. Acamprosate:
Acamprosate is used in the maintenance phase of alcohol use disorder treatment. It helps individuals maintain abstinence by stabilizing the chemical imbalances in the brain that occur after prolonged alcohol use. Acamprosate is not used for acute withdrawal management but is instead prescribed to support individuals who have already stopped drinking and are trying to avoid relapse over the long term.

A. "Since injuring my knee, I've decided to become the team manager."
Option A represents an adaptive use of the ego defense mechanism known as sublimation. Sublimation is a process in which a person channels potentially negative or harmful impulses or feelings into more socially acceptable and constructive activities. In this case, the adolescent with the injured knee is using the opportunity to become the team manager, which is a positive and constructive way to stay engaged with the team despite the setback of the injury.

B. "Since my mom died, I focus all my attention on my grades."
This is an example of reaction formation, a defense mechanism where someone overemphasizes the opposite of their true feelings. In this case, the individual might be hiding or avoiding their grief by focusing on grades.

C. "I didn't tell the teacher about the bullying because it wouldn't have changed anything."
This is an example of rationalization, where the individual provides a logical-sounding but potentially inaccurate explanation for their actions. It can be a defense mechanism to justify or make more acceptable one's choices.

D. "I'm not even going to think about writing that thesis paper until after prom."
This is an example of procrastination or avoidance, which is not an ego defense mechanism but a coping or time-management strategy. It doesn't represent an adaptive use of a defense mechanism in this context.
