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 A
Explanation
Choice A rationale:
Protecting the client from injury is the highest priority nursing action in this scenario. Here's a detailed rationale explaining the importance of this action:
1. Imminent Risk of Harm:
Acute anxiety can significantly impair judgment and impulse control, escalating the risk of self-harm or harm to others. It's crucial to prevent any actions that could result in physical injury, even if unintended.
2. Physiological Manifestations:
Anxiety can trigger physiological responses that heighten the potential for harm, such as: Increased heart rate and blood pressure
Hyperventilation Diaphoresis
Agitation and restlessness Dissociation
These physiological changes can contribute to accidents, falls, or other injuries.
3. Impaired Decision-Making:
Acute anxiety often clouds rational thinking and decision-making abilities.
Individuals may engage in behaviors they wouldn't consider in a calmer state, such as running away, lashing out, or attempting self-harm.
The nurse's role is to safeguard the client from potential consequences of these impulsive actions.
4. Establishing Safety as a Foundation for Care:
Ensuring physical safety creates a necessary foundation for subsequent interventions.
Once safety is established, the nurse can proceed with assessing coping skills, identifying anxiety triggers, and implementing therapeutic strategies.
5. Protecting Others:
In rare cases, acute anxiety can manifest in aggression towards others.
The nurse must protect not only the client but also other individuals who may be at risk.
6. Ethical and Legal Obligations:
Nurses have a professional duty to protect clients from harm, upholding ethical principles and legal standards of care.
7. Preventing Trauma:
Physical injuries sustained during a crisis can exacerbate anxiety and complicate recovery. Proactive safety measures aim to prevent further trauma and promote healing.
I'll provide detailed rationales for the other choices in separate messages to ensure clarity and comprehensiveness.
Correct Answer is D
Explanation
Choice A rationale:
Deflecting the client's concerns to the physician dismisses the client's immediate need for emotional support and therapeutic communication.
It can hinder the development of a trusting nurse-client relationship.
The nurse is responsible for addressing the client's psychosocial needs, not solely deferring them to other healthcare professionals.
Choice B rationale:
Offering false reassurance is inappropriate and potentially harmful. It can erode trust if the client's fears are later realized.
It minimizes the client's legitimate concerns and invalidates their emotional experience.
Choice C rationale:
While lifestyle modifications are essential for managing coronary artery disease, providing unsolicited advice at this moment disregards the client's emotional distress.
It prioritizes physical health over the client's psychological well-being. It can be perceived as dismissive of the client's fears and concerns.
Choice D rationale:
Inviting the client to elaborate on their fears demonstrates active listening and encourages therapeutic communication. It validates the client's concerns and shows empathy for their emotional experience.
It provides an opportunity to assess the client's understanding of their condition and identify specific fears or misconceptions. It establishes a foundation for exploring coping mechanisms and providing appropriate support and education.
