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.

Explanation
The correct answer/s is Choice/s.
Choice A rationale: Mental health support is generally considered a protective factor against suicide. Effective mental health care can help individuals manage their mental health conditions, which can reduce the risk of suicide.
Choice B rationale: Family history, particularly a family history of suicide, is a risk factor for suicide. The client’s mother’s suicide could potentially increase the client’s risk.
Choice C rationale: Good physical health is typically seen as a protective factor against suicide. Serious physical health conditions, including chronic pain, can increase suicide risk, but the client is reported to be in good physical health.
Choice D rationale: Support systems, such as feeling connected to family and community, are protective factors against suicide. They can provide emotional support and help individuals feel less isolated.
Choice E rationale: Alcohol consumption, especially misuse or addiction, is a risk factor for suicide. However, the client has attended rehabilitation and has not used alcohol for the past 4 years, which could be seen as a protective factor.
Choice F rationale: Access to lethal means is a risk factor for suicide. Limiting access to lethal means is a societal protective factor.
Correct Answer is D
Explanation
Choice A: History of bulimia nervosa: While eating disorders can be comorbid with self-harm, bulimia nervosa specifically is not a strong independent risk factor for self-harm. The focus of bulimia nervosa lies on purging behaviors to counteract weight gain, and while self-harm can co-occur, it's not directly linked to the core symptoms of the eating disorder.
Choice B: Parent with dependent personality disorder: Personality disorders in family members can create complex family dynamics and contribute to emotional distress, but inheriting a personality disorder is not possible.
Additionally, dependent personality disorder specifically is characterized by excessive reliance on others, not behaviors associated with increased risk for self-harm.
Choice C: Recent promotion at work: Positive life events like a promotion are unlikely to directly increase the risk of self-harm. In fact, achieving goals and milestones can be protective factors for mental health.
Choice D: Borderline personality disorder: Borderline personality disorder (BPD) is a well-established risk factor for self-harm. Individuals with BPD often experience emotional dysregulation, impulsivity, and fear of abandonment, which can lead to self-injurious behaviors as a coping mechanism. The intense emotions and unstable interpersonal relationships associated with BPD make individuals more vulnerable to engaging in self-harm to manage overwhelming distress.
Further Explanation:
BPD is characterized by a pattern of five or more of the following symptoms:
Fear of abandonment: Frantic efforts to avoid real or imagined abandonment.
Unstable relationships: Intense and unstable relationships with a pattern of idealization and devaluation. Identity disturbance: Markedly unstable sense of self-image or self-worth.
Impulsivity: In at least two areas that are potentially damaging (e.g., spending, unsafe sex, substance abuse). Suicidality: Recurrent suicidal threats, gestures, or attempts, or self-mutilating behavior.
Affective instability: Marked mood swings (e.g., intense episodes of anger, dysphoria, anxiety, or despair lasting a few hours and up to a few days).
Chronic emptiness: Feelings of emptiness or boredom.
Dissociation: Transient, stress-related episodes of derealization or depersonalization.
Research indicates that individuals with BPD have a significantly higher risk of self-harm compared to the general population, with estimates ranging from 70% to 90%. This increased risk is attributed to several factors associated with BPD, such as:
Emotional dysregulation: Difficulty managing intense emotions, leading to self-harm as a way to cope with overwhelming distress.
Impulsivity: Engaging in harmful behaviors without considering the consequences, including self-harm.
Fear of abandonment: Self-harm can be used as a way to punish oneself or manipulate others to prevent perceived abandonment.
Negative self-image: Low self-esteem and feelings of worthlessness can contribute to self-harming behaviors as a form of self-punishment.
Conclusion:
While other factors may contribute to self-harm risk, borderline personality disorder remains a significant and well- established risk factor. A mental health nurse reviewing a client's medical record should prioritize identifying BPD as a potential indicator of increased risk for self-harm behaviors.
