A nurse is preparing to administer fluoxetine 40 mg PO daily.
The amount available is fluoxetine 20 mg/5mL.
How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies.Do not use a trailing zero.).
The Correct Answer is ["10"]
To calculate the amount of fluoxetine to administer, we can use the following steps:
Step 1: Identify the desired dose, which is 40 mg.
Step 2: Identify the available dose, which is 20 mg/5 mL.
Step 3: Set up the equation to solve for the unknown, which is the volume in mL. The equation is (Desired Dose ÷ Available Dose) × Volume = Volume to Administer.
Step 4: Substitute the known values into the equation: (40 mg ÷ 20 mg) × 5 mL = Volume to Administer. Step 5: Solve the equation: 2 × 5 mL = 10 mL.
So, the nurse should administer 10 mL of fluoxetine.

Correct Answer is D
Explanation
Choice A rationale: A client with Obsessive Compulsive Disorder (OCD) who insists on mopping the floor in the day room does not pose a direct threat to themselves or others. OCD is characterized by obsessions (persistent, intrusive
thoughts) and compulsions (repetitive behaviors that the person feels compelled to perform). The act of mopping the floor could be a compulsion for this client. While it may be disruptive or unusual, it is not harmful. Therefore, restraints would not be appropriate in this situation.
Choice B rationale: A client with a personality disorder who tries to manipulate staff to gain privileges can be challenging to manage, but this behavior does not warrant the use of restraints. Personality disorders are characterized by enduring patterns of behavior, cognition, and inner experience that deviate from the expectations of the individual’s culture. These patterns are inflexible and pervasive across many personal and social situations.
While manipulation can be frustrating for staff, it is not a danger to the client or others, and other interventions should be used to manage this behavior.
Choice C rationale: A client with Bulimia Nervosa who refuses to come to the dining room for meals is exhibiting behavior related to their eating disorder, but this does not justify the use of restraints. Bulimia Nervosa is characterized by recurrent episodes of binge eating followed by compensatory behaviors such as vomiting, fasting, or excessive exercise. Refusal to eat in a communal setting like a dining room is not uncommon for individuals with eating disorders. This behavior should be addressed through therapeutic interventions, not restraints.
Choice D rationale: A client who is just recovering from a benzodiazepine overdose is the correct answer. Restraints are contraindicated for this client because they could cause physical harm. After a benzodiazepine overdose, the client may experience symptoms such as drowsiness, confusion, and impaired coordination. Restraints could increase the risk of injury, particularly if the client becomes agitated or tries to remove them. In addition, restraints could potentially interfere with medical treatment for the overdose.
Correct Answer is D
Explanation
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.
