A patient experiencing delirium secondary to corticosteroid toxicity is manifesting paranoid thinking and noisy, assaultive behavior. The patient is currently pacing the hall and shouting. A nurse has placed a call to the physician and is anticipating the following order:
- A. the use of supervised restraints.
- B. a loading dose of phenytoin.
- C. a small dose of prednisone.
- D. an IV dose of thiamine.
Correct Answer: A
Rationale: The correct answer is A: the use of supervised restraints. In this situation, the patient is displaying agitated and assaultive behavior, posing a risk to themselves and others. Supervised restraints are necessary to ensure the safety of the patient and healthcare providers until the effects of corticosteroid toxicity subside. Restraints should only be used as a last resort when other interventions have failed.
Choice B: A loading dose of phenytoin is incorrect because phenytoin is not indicated for managing delirium secondary to corticosteroid toxicity.
Choice C: A small dose of prednisone is incorrect because adding more corticosteroids would exacerbate the toxicity and worsen the delirium.
Choice D: An IV dose of thiamine is incorrect as thiamine is used to treat thiamine deficiency, not corticosteroid toxicity-induced delirium.
In the elderly, administering medication is a great concern for the nurse since these patients are more prone to side effects. The primary cause of this is:
- A. Altered circulation and renal function
- B. Accelerated gastrointestinal system
- C. Enlarged Lymph nodes
- D. Musculoskeletal system weakness
Correct Answer: A
Rationale: The elderly are more likely to have side effects when there is altered metabolism through the kidneys and liver as well as altered circulatory function (A), unlike the other options (B, C, D) which are less relevant.
A school-aged patient with attention-deficit hyperactivity disorder (ADHD) is displaying disruptive behaviors at home. The psychiatric-mental health nurse modifies the treatment plan for the social domain, by advising the patient's parents to:
- A. establish eye contact before giving directions
- B. initiate a point system, to reward the patient for appropriate behavior
- C. instruct the patient to work on one homework assignment at a time
- D. maintain a predictable environment in the home
Correct Answer: B
Rationale: A point system reinforces positive behavior, directly addressing social disruptiveness in ADHD.
The physician and advanced practice nurse are considering which antipsychotic medication to prescribe for a patient with schizophrenia who demonstrates auditory hallucinations, apathy, anhedonia, and poor social functioning. The patient is overweight and has hypertension. Bearing these facts in mind, the drug the nurse should advocate would be:
- A. clozapine (Clozaril).
- B. haloperidol (Haldol).
- C. olanzapine (Zyprexa).
- D. aripiprazole (Abilify).
Correct Answer: D
Rationale: The correct answer is D: aripiprazole (Abilify). Aripiprazole is a second-generation antipsychotic that is less likely to cause weight gain and metabolic side effects compared to other antipsychotics. This is important since the patient is already overweight and has hypertension. Aripiprazole also has a lower risk of causing sedation, which can be beneficial for addressing apathy and anhedonia without worsening social functioning.
A: Clozapine is effective for treatment-resistant schizophrenia but is associated with significant weight gain and metabolic side effects.
B: Haloperidol is a first-generation antipsychotic with a high risk of extrapyramidal side effects and is not ideal for a patient with hypertension.
C: Olanzapine is known for causing significant weight gain and metabolic effects, making it a less suitable choice for an overweight patient with hypertension.
A 75-year-old male client is brought to the clinic by his son. The son states, 'Ever since Mom died, Dad hasn't been the same. At first he just seemed sad, but now he seems to get mixed up about everything.' The nurse is aware that based on the client's history, the source of confusion is most likely:
- A. Dementia
- B. Depression from the loss of his wife
- C. Hypoxia of the brain
- D. Delirium from medications
Correct Answer: B
Rationale: Correct Answer: B - Depression from the loss of his wife
Rationale: Given the client's recent loss of his wife and subsequent changes in behavior, the most likely cause of his confusion is depression. Depression can manifest as cognitive impairment in older adults, leading to symptoms such as confusion and memory problems. Additionally, grief and loss can exacerbate depressive symptoms in elderly individuals, further contributing to cognitive difficulties.
Summary of other choices:
A: Dementia - Dementia typically presents with gradual cognitive decline over time, not a sudden onset following a specific event like the loss of a loved one.
C: Hypoxia of the brain - Hypoxia would likely present with more acute symptoms and physical signs, such as shortness of breath or cyanosis.
D: Delirium from medications - Delirium is characterized by acute onset and fluctuating course, often related to medication changes or other medical conditions, rather than an emotional trigger like grief.
