A nurse in a mental health unit is admitting a female client who has anorexia nervosa.
The admission vital signs are as follows: Heart rate 52/min, Respiratory rate 26/min, Blood pressure 84/50 mm Hg, Temperature 36.1C(97F). The nurse should first address the client's:

Choice A: Limit the amount of time available to interact with others

While the client's behavior may indirectly limit their interactions with others by occupying their time, this is not the primary function of their actions. The core motivation lies in reducing anxiety, not social avoidance.

Choice B: Manipulate and control others' behaviors

Although the client's cleaning may influence others to tidy up, this is not a deliberate attempt to control their behavior. The primary drive stems from the client's internal need for order and cleanliness, not a desire to dictate the actions of others.

Choice C: Focus attention on meaningful tasks

While the act of cleaning can be productive and contribute to a pleasant environment, it's not the primary function or intention behind the client's behavior. Their actions are primarily driven by the need to quell anxiety, not necessarily to accomplish meaningful tasks.

Choice D: Decrease anxiety to a tolerable level

This is the most accurate rationale for the client's behavior. Individuals with OCD engage in compulsions, like excessive cleaning, to alleviate the intense anxiety associated with their intrusive thoughts and obsessions. In this case, the act of picking up after others provides the client with a sense of order and control, thereby reducing their anxiety to a manageable level.

Elaboration:

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions). Individuals with OCD experience significant anxiety due to their obsessions and feel compelled to engage in compulsions to manage that anxiety.

In the scenario presented, the client's constant cleaning behavior likely stems from an obsession with order and cleanliness. This obsession triggers anxiety when the environment is perceived as messy or disorderly. The act of picking up after others serves as a compulsion, a ritualistic behavior performed to reduce the anxiety caused by the obsession. By restoring order and cleanliness, the client temporarily alleviates their anxiety and achieves a sense of control over their environment.

It's important to recognize that the client's cleaning behavior, while seemingly productive, is primarily driven by their internal need to manage anxiety, not by a genuine desire to help others or maintain a tidy environment. This understanding is crucial for the nurse to effectively support the client and guide them towards healthier coping mechanisms for managing their OCD symptoms.

Step 1: Identify the required dose of lithium, which is 300 mg.

Step 2: Identify the available dose of lithium carbonate, which is 150 mg per capsule.

Step 3: Calculate the number of capsules needed using the formula: Number of capsules = Required dose ÷ Available dose.

Numberofcapsules=300 mg150 mg/capsule

\(Number\ of\ capsules = {300\ mg \over 150\ mg/capsule}\)

Step 4: Solve the equation.

Numberofcapsules=2 capsulesNumberofcapsules=2capsules

So, the nurse should administer 2 capsules per dose to achieve the required lithium dose of 300 mg.
