Question 1
Regular
A nurse is performing an admission assessment. The patient complains that it has been taking larger and larger amounts of medication to get the desired effect. Based on this information, the nurse interprets this as suggesting which of the following?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Tolerance. The patient’s report of needing increased medication to achieve the same effect indicates a physiological adaptation to the drug, which is characteristic of tolerance, commonly seen with prolonged medication use.
A: Desensitization. This term refers to a reduction in response to a stimulus after repeated exposure, but it does not specifically relate to increasing medication doses for effect.
C: Therapeutic index. This concept describes the range between effective and toxic drug doses and does not pertain to the gradual increase in medication required for effect.
D: Toxicity. Toxicity refers to harmful effects resulting from excessive medication intake, which is distinct from the patient’s experience of needing larger doses for the desired effect.

Question 2
Regular
An older adult is complaining of anxiety is prescribed diazepam (Valium) by a family physician. The physician asks the office nurse to explain the problematic side effects of this medication to the patient. Which instruction would be most important for the nurse to emphasize about this drug?
Correct!
Incorrect
The correct answer is: D
Rationale
You may feel dizzy and be prone to falls after taking this medication. The sedative effects of diazepam can lead to decreased coordination and balance, particularly in older adults, increasing the risk of falls and related injuries, which is a significant concern for their safety and well-being.
A: You may experience minor urine incontinence from time to time. While incontinence can occur, it is not a primary or significant side effect associated with diazepam use, making this less critical to emphasize.
B: You may find that you have temporary memory disturbances. Although cognitive effects can occur, the immediate risk of dizziness and falls poses a more pressing danger for older adults than memory disturbances.
C: You need to use this medication cautiously because it can cause dependence. Dependence is a valid concern, yet the immediate dangers of dizziness and falls are more pressing for the patient’s current safety.

Question 3
Regular
A nurse is caring for a psychiatric patient who is receiving an antacid that contains aluminum salts. Which action by the nurse would be most appropriate?
Correct!
Incorrect
The correct answer is: A
Rationale
Administer the antacid 1 hour before the antipsychotic medication. This timing prevents the aluminum salts in the antacid from interfering with the absorption of the antipsychotic, ensuring effective medication delivery and optimal therapeutic outcomes for the patient.
B: Give the antacid at the same time as the antipsychotic medication. Administering both simultaneously can hinder the absorption of the antipsychotic, potentially reducing its effectiveness and compromising the patient's treatment.
C: Administer the antacid 1 hour after the antipsychotic medication. Giving the antacid after the antipsychotic may not allow for proper absorption of the latter, diminishing its therapeutic impact.
D: Administer the antacid just before the patient goes to sleep. Timing the antacid close to sleep may disrupt medication efficacy, as it can interfere with the absorption of the antipsychotic taken earlier.
Correct Answer: A

Question 4
Regular
A patient is prescribed medication for a psychiatric disorder. After 3 days, the patient tells the nurse that he or she has been constipated. Which instruction would the nurse give the patient?
Correct!
Incorrect
The correct answer is: B
Rationale
You need to eat more fruits and vegetables and drink more water. Increasing fiber intake and hydration can alleviate constipation, which is a common side effect of certain psychiatric medications.
A: You need to eat more high-protein foods such as meat and peanut butter. High-protein foods do not address the hydration and fiber needs essential for relieving constipation.
C: Ask your psychiatrist to prescribe a stool softener for you. While stool softeners can help, dietary changes are a more immediate and preventive approach to managing constipation.
D: This side effect should disappear within a week or so. Constipation may persist without intervention, and proactive measures like dietary adjustments are necessary for effective relief.

Question 5
Regular
The nurse is caring for a 70-year-old psychiatric patient who has been prescribed a number of medications. When teaching the patient about the medications, which explanation would be most appropriate?
Correct!
Incorrect
The correct answer is: C
Rationale
Because of your age and related changes in liver functioning, you may have medication levels in your system with the potential to be toxic.
Age-related liver function decline can affect drug metabolism, leading to increased toxicity risks. Understanding this is crucial for elderly patients, as they are more susceptible to adverse effects from medications, necessitating careful monitoring and dosage adjustments to ensure safety and efficacy in treatment.
A: Your stomach empties more quickly as you age; therefore, you may feel the effect of your medications almost immediately. Aging does not universally speed up gastric emptying; it can actually slow down, affecting medication absorption unpredictably.
B: Your entire GI system speeds up, so your medications are digested much more quickly. Therefore, it is important that you not drive after you take your medications. An accelerated gastrointestinal system is not typical for older adults, thus this statement misrepresents the physiological changes that occur with aging.
D: Because of age-related circulation changes, your body will be able to deliver therapeutic doses of your medication to select body sites more quickly. Age impacts circulation in ways that may hinder, rather than enhance, the efficient delivery of medications to target areas, complicating treatment outcomes.

Question 6
Regular
During the stabilization phase of drug therapy for a patient who is hospitalized with a psychiatric disorder, which action would be most appropriate?
Correct!
Incorrect
The correct answer is: D
Rationale
During the stabilization phase of drug therapy, assessing the patient for target symptoms and side effects is most appropriate. This evaluation ensures that the medication is effectively managing symptoms and allows for necessary adjustments to optimize the treatment plan.
A: Discussing the timing of tapering the medication focuses on future changes rather than current stabilization needs. Immediate assessment of symptoms and side effects takes precedence during this critical phase.
B: Instructing the patient about relapse prevention emphasizes long-term strategies, which are less relevant during the immediate stabilization phase. Current symptom management should be prioritized for optimal care.
C: Determining if the medication is losing its effect may be important but is secondary to directly assessing the patient's ongoing response. Immediate evaluation provides more critical information for treatment adjustments.

Correct!
Incorrect
The correct answer is: D
Rationale
D: Agranulocytosis
Clozapine is associated with agranulocytosis, a severe drop in white blood cells. The patient's symptoms—fever, sore throat, and mouth sores—are indicative of this serious condition, necessitating immediate medical evaluation.
A: Severe anemia
The patient's symptoms do not align with severe anemia, which typically presents with fatigue, pallor, and shortness of breath, rather than fever or mouth sores.
B: Neuroleptic malignant syndrome
Neuroleptic malignant syndrome primarily involves muscle rigidity, high fever, and autonomic instability. The specific symptoms of sore throat and mouth sores do not match this diagnosis.
C: Encephalitis
Encephalitis usually presents with neurological symptoms such as seizures, confusion, or altered consciousness. The patient's primary complaints do not reflect the typical manifestations of this condition.

Question 21
Multiple Choice
A nurse is preparing a patient for electroconvulsive therapy. Which of the following would the nurse include in the patient?s plan of care? Select all that apply.
Correct!
Incorrect
The correct answer is: A,C,E
Rationale
Ensuring that there is a signed informed consent on the patient’s chart, alerting the patient to the possibility of confusion after the treatment, and ensuring that the patient is closely supervised for at least the first 12 hours afterward are essential components of the patient's plan of care for electroconvulsive therapy.
A: Ensuring that there is a signed informed consent on the patient’s chart is vital, as it confirms the patient's understanding and agreement regarding the procedure and its potential risks.
B: Telling the patient he can have fluids but no food before the procedure does not encompass the necessary pre-procedural guidelines, which typically require fasting to reduce aspiration risk during anesthesia.
D: Informing the patient that he can leave his dentures in place for the treatment neglects safety protocols, as dentures may interfere with airway management during the procedure or pose risks if dislodged.
C: Alerting the patient to the possibility of confusion after the treatment is crucial, as patients often experience temporary cognitive effects post-therapy that need to be communicated and monitored effectively.
E: Ensuring that the patient is closely supervised for at least the first 12 hours afterward is critical for safety, as patients may experience side effects that require immediate medical attention during this recovery period.

Question 22
Regular
The nurse is reviewing the medical records of several patients receiving antipsychotic agents. Which factors, if noted, would the nurse identify as placing a patient at greater risk for tardive dyskinesia?
Correct!
Incorrect
The correct answer is: NONE
Rationale
None. Tardive dyskinesia is primarily associated with long-term use of antipsychotic medications, rather than demographic factors like gender, age, or mental health history. Thus, none of the options provided directly contribute to an increased risk.
A: Male gender does not inherently increase the likelihood of developing tardive dyskinesia, as the condition affects individuals regardless of gender.
B: Age 30 to 45 years does not specifically heighten the risk for tardive dyskinesia; the condition is more closely linked to prolonged medication exposure.
C: History of depression does not correlate with a greater susceptibility to tardive dyskinesia, as the disorder arises primarily from chronic antipsychotic treatment rather than prior mental health issues.
D: Short duration of treatment typically reduces the risk of tardive dyskinesia, as the condition develops over extended periods of antipsychotic usage, not with brief exposure.

Question 23
Regular
A patient is experiencing hallucinations and delusions. The nurse would expect the physician to order which class of drug?
Correct!
Incorrect
The correct answer is: B
Rationale
Antipsychotic. This class of medication is specifically designed to manage symptoms such as hallucinations and delusions, commonly associated with conditions like schizophrenia or severe mood disorders, making it the most appropriate choice.
A: Mood stabilizer. This type of drug primarily addresses mood fluctuations and is not tailored to alleviate psychotic symptoms like hallucinations or delusions, thus lacking effectiveness in this scenario.
C: Antianxiety agent. These medications focus on reducing anxiety and do not target the psychotic symptoms of hallucinations and delusions, failing to provide appropriate treatment for the patient's condition.
D: Stimulant. Stimulants are used to enhance alertness or attention and could exacerbate psychotic symptoms, making them unsuitable for treating hallucinations and delusions in the patient’s context.

Question 24
Regular
After teaching a patient who is receiving phenelzine, the nurse determines that the teaching was successful when the patient states the need to avoid which of the following?
Correct!
Incorrect
The correct answer is: C
Rationale
Tap beers. Phenelzine is a monoamine oxidase inhibitor (MAOI), and consuming tap beers can lead to hypertensive crises due to tyramine interaction, which is crucial for patients to understand for their safety.
A: Fresh cottage cheese. It contains low levels of tyramine, making it generally safe for patients on phenelzine, thus not requiring strict avoidance like more tyramine-rich foods.
B: Cooked sliced ham. While it has some tyramine, it is not as high as certain fermented products, meaning it does not pose the same significant risk as tap beers.
D: Soy milk. This option typically contains minimal tyramine content, and therefore does not necessitate the same level of caution as beverages like tap beers for those taking phenelzine.

Question 25
Multiple Choice
A group of nursing students are reviewing the various drug classes used to treat psychiatric disorders. The students demonstrate understanding when they identify which of the following as examples of antianxiety medications? Select all that apply.
Correct!
Incorrect
The correct answer is: B,C
Rationale
Lorazepam and Buspirone are examples of antianxiety medications. These drugs specifically target anxiety symptoms, with Lorazepam acting as a benzodiazepine providing rapid relief, while Buspirone offers a non-benzodiazepine alternative for chronic anxiety management.
A: Selegiline This medication primarily functions as an MAOI, focusing on treating depression rather than anxiety disorders, thus not fitting within the antianxiety category.
D: Zolpidem While Zolpidem is used for insomnia, it does not address anxiety disorders, placing it outside the scope of antianxiety medications.
E: Methylphenidate This stimulant is primarily utilized for ADHD treatment, lacking effectiveness in addressing anxiety symptoms, which excludes it from antianxiety classifications.
