A patient with Schizophrenia has been prescribed an antipsychotic medication. They return to the clinic complaining they are experiencing leaking from their breasts. What drug would the nurse assume is responsible for this side effect?
Loxapine
Risperidone
Zyprexa
Haldol
The Correct Answer is B
Reasoning:
Choice A reason: Loxapine is a typical antipsychotic of the dibenzoxazepine class. While it can cause some elevation in prolactin levels, it is significantly less associated with symptomatic galactorrhea (breast leaking) compared to other agents, particularly among the newer second-generation antipsychotics like Risperidone.
Choice B reason: Risperidone is well-known for causing significant hyperprolactinemia. It has a high affinity for dopamine D2 receptors in the tuberoinfundibular pathway. By blocking dopamine, which normally inhibits prolactin release, it leads to excessive prolactin secretion, resulting in galactorrhea, gynecomastia, and menstrual irregularities in patients.
Choice C reason: Zyprexa (Olanzapine) is a second-generation antipsychotic that generally has a lower risk of causing sustained hyperprolactinemia compared to Risperidone. While it can occasionally cause slight elevations in prolactin, it is rarely the primary suspect for clinically significant breast leaking in psychiatric practice.
Choice D reason: Haldol (Haloperidol) is a high-potency first-generation antipsychotic. Although it can cause prolactin elevation due to potent D2 receptor blockade, Risperidone is more frequently cited in modern clinical literature for causing the highest levels of prolactin among the commonly used second-generation antipsychotics.

Correct Answer is A
Explanation
Reasoning:
Choice A reason: Apraxia is a neurological condition, often seen in dementia or following a stroke, where a patient is unable to perform purposeful, learned movements despite having the physical strength and desire to do so. It involves a breakdown in the brain's ability to plan and execute the complex motor sequence.
Choice B reason: This choice describes agnosia, which is the inability to process sensory information and recognize objects, people, or sounds. While apraxia and agnosia often co-occur in neurodegenerative diseases like Alzheimer's, agnosia specifically refers to a deficit in recognition and perception rather than the physical execution of motor tasks.
Choice C reason: A lack of interest or ability to begin activities is known as avolition or apathy. This is a common negative symptom in schizophrenia and a frequent symptom of depression. It is a deficit of will or motivation rather than a neurological impairment of the motor planning system required for movement.
Choice D reason: A language disturbance is referred to as aphasia. Aphasia can involve difficulty producing speech (expressive) or understanding speech (receptive). While aphasia and apraxia are both cognitive impairments resulting from cortical damage, apraxia specifically relates to the physical "doing" of tasks rather than the communication of thoughts.
Correct Answer is C
Explanation
Reasoning:
Choice A reason: The health care provider (physician or NP) is responsible for the legal order and the medical justification for the restraint. However, they are not present for the continuous monitoring and physical safety of the patient. The ongoing assessment of the patient's physical and psychological status falls under nursing care.
Choice B reason: While unlicensed assistive personnel (UAP) may assist in the physical application or perform specific monitoring tasks under the nurse's delegation, the ultimate professional and legal accountability for the patient’s safety and the correct implementation of the restraint protocol rests with the licensed nurse overseeing the care.
Choice C reason: The registered nurse is legally and professionally responsible for the safety of a restrained patient. This includes performing frequent assessments of skin integrity, circulation, and respiratory status, ensuring the restraint is applied correctly, and evaluating the patient's ongoing need for the restrictive measure to prevent injury or complications.
Choice D reason: Family members may provide consent for a restraint in some long-term care scenarios, but they hold no professional or legal responsibility for the safe application or monitoring of the device. The duty of care and the responsibility for maintaining a safe clinical environment belong exclusively to the healthcare team.
