A patient is prescribed 150 mg of a psychotropic medication administered IM every 6 hours. The pharmacy provides you with a vial containing 300 mg/2 mL How many milliliters should you administer per dose?
2 mL
0.5 mL
3 mL
1 mL
The Correct Answer is D
A. This would provide 300 mg, which is double the prescribed dose.
B. This error often occurs if a student divides 150 by 300 but forgets to multiply by the quantity (2 mL). This would only provide 75 mg.
C. This value is mathematically unrelated to the variables and would result in an overdose of 450 mg.
D. Step 1: Use the formula- Volume to administer (mL) = Desired dose ÷ Concentration. Step 2: Determine the concentration in mg/mL. Concentration = 300 mg ÷ 2 mL = 150 mg/mL. Step 3: Insert known values (Desired dose = 150 mg, Concentration = 150 mg/mL). Volume to administer = 150 ÷ 150= 1 mL.

Correct Answer is ["A","D","E","F"]
Explanation
A. Abusive individuals frequently use intimidation, threats, or coercion to control others. This can be verbal, emotional, or physical and serves to maintain power and dominance over victims. Recognizing this behavior allows nurses to implement safety measures for both staff and other clients.
B. Communication style alone, such as brevity of speech, is not a reliable indicator of abusive tendencies. Abusers may be articulate or manipulative in speech; the key factor is their pattern of controlling or aggressive behavior, not sentence length.
C. Bravery or courage is a neutral trait and is not directly linked to a history of abuse. While abusers may present as confident, the presence of “bravery” does not predict abusive behavior.
D. Abusive individuals often have poor impulse control and may react aggressively when frustrated, annoyed, or challenged. Low frustration tolerance can manifest as verbal outbursts, threats, or physical aggression, making this a key behavioral marker.
E. Many perpetrators of abuse struggle with underlying insecurities. Aggression, control, or manipulation is sometimes a way to compensate for feelings of inadequacy or low self-worth. Recognizing low self-esteem can inform interventions aimed at behavioral modification or therapy.
F. Abusive individuals may exhibit controlling and demanding behaviors, expecting others to comply with their wishes and reacting negatively when boundaries are set or expectations are unmet. This trait reinforces the power imbalance often central to abusive dynamics.
Correct Answer is C
Explanation
A. Keeping the client’s environment calm with minimal daily stimuli is an immediate or short-term intervention to reduce agitation and sensory overload. While helpful during acute episodes, it does not address long-term management or prevention of relapse.
B. Ensuring the client participates in a walk with staff daily is also a short-term, behavioral intervention aimed at promoting physical activity and engagement. This supports overall wellness but is not a long-term goal for relapse prevention.
C. Developing and acknowledging understanding of a relapse plan prior to discharge is correct. A long-term goal in the management of schizophrenia focuses on relapse prevention and medication adherence. By educating the client about early warning signs, triggers, and strategies for intervention, the nurse empowers the client to recognize and act on symptoms promptly, reducing the risk of future rehospitalization and promoting sustained recovery.
D. Being reoriented to the current environment as needed is a short-term supportive goal used during acute psychosis to reduce confusion. It does not address long-term outcomes or relapse prevention.
