A 54 year old client is admitted with an exacerbation of COPD. The patient weighs 95kg. The healthcare provider orders theophylline IV per protocol: Loading dose 6 mg/kg. The pharmacy sends you 250 mg/10 ml of theophylline.
Calculate the ml for the loading dose of theophylline.
The Correct Answer is ["22.8"]
Calculation:
- Calculate the total dose in milligrams (mg) for the client's weight.
Total dose (mg) = Patient weight (kg) x Ordered dose (mg/kg)
= 95 kg x 6 mg/kg
= 570 mg.
Available concentration = 250 mg / 10 mL
= 25 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Total dose (mg) / Available concentration (mg/mL)
= 570 mg / 25 mg/mL
= 22.8 mL.

Correct Answer is C
Explanation
A. Depressive characteristics of schizophrenia: While some atypical antipsychotics may have mood-stabilizing effects, paliperidone is not primarily indicated for treating depressive symptoms. Antidepressants are more effective for depressive features rather than antipsychotic agents.
B. Negative symptoms of schizophrenia only: Paliperidone helps address negative symptoms such as social withdrawal and blunted affect, but it is not limited to these alone. Its mechanism of action also targets positive symptoms, making this option incomplete.
C. Both positive and negative symptoms of schizophrenia: Paliperidone, an atypical antipsychotic, blocks dopamine D2 receptors and serotonin 5-HT2A receptors. This dual action makes it effective for reducing hallucinations and delusions (positive symptoms) as well as improving motivation and affect (negative symptoms).
D. Low serotonin levels: Paliperidone does act on serotonin receptors, but it does not treat “low serotonin levels” as a standalone condition. Instead, the benefit is its balanced effect on both dopamine and serotonin pathways, reducing positive and negative symptoms in schizophrenia.
Correct Answer is B
Explanation
A. Highly self-directed people reflect low intolerance of change: This description does not explain the development of personality disorders. Self-direction is generally considered a positive trait that supports adaptability, not a factor leading to pathology.
B. Failure to complete developmental tasks: According to Erikson and other developmental theories, unresolved developmental stages such as trust, identity, or intimacy can lead to maladaptive coping patterns that evolve into personality disorders.
C. Cooperative people become less helpless over time: This reflects a positive growth pattern, not a factor in personality disorder development. Increased cooperation typically strengthens relationships and resilience rather than causing pathology.
D. Self-transcendence contributes to unaware self-consciousness: Self-transcendence is usually considered a positive quality associated with spirituality or meaning-making, not a cause of disordered personality development.
