Question 2 of 5
A client diagnosed with schizophrenia is slow to respond and appears to be listening to unseen others. Which medication should a nurse expect a physician to order to address this type of symptom?
Correct Answer: C
Rationale: The correct answer is C: Risperidone (Risperdal) to address the positive symptom of hallucinations. Risperidone is an atypical antipsychotic commonly used to treat schizophrenia symptoms such as hallucinations and delusions. It works by blocking dopamine and serotonin receptors in the brain, helping to reduce hallucinations. A: Haloperidol (Haldol) is an older typical antipsychotic that is more commonly used for treating positive symptoms like hallucinations and delusions, not negative symptoms like social withdrawal or lack of motivation. B: Clonazepam (Klonopin) is a benzodiazepine used to treat anxiety and seizures, not typically used for treating the positive symptoms of schizophrenia. D: Clozapine (Clozaril) is typically reserved for treatment-resistant schizophrenia and is more effective in addressing negative symptoms like social withdrawal and lack of motivation, rather than positive symptoms like hallucinations.
Question 3 of 5
Which of the client’s neurotransmitters should a nurse expect to be elevated?
Correct Answer: B
Rationale: The correct answer is B: Dopamine. Dopamine is a neurotransmitter associated with pleasure, reward, and motivation. Elevated levels of dopamine can be seen in conditions like schizophrenia and mania. Serotonin is more related to mood regulation, GABA to inhibitory neurotransmission, and histamine to allergic responses, making them less likely to be elevated in this context.
Question 4 of 5
A patient being treated for depression has been taking 300 mg amitriptyline (Elavil) daily for nearly a year. She calls her case manager at the mental health clinic, stating she stopped taking her antidepressant 2 days ago and has developed something like the “flu,” with cold sweats, nausea, a rapid heartbeat, terrible nightmares when she sleeps, but no other symptoms. How should the nurse respond?
Correct Answer: C
Rationale: The correct answer is C: Explain it may be withdrawal; tell her to take one Elavil and contact her doctor. This response is appropriate because the patient is experiencing symptoms consistent with abrupt discontinuation of amitriptyline, known as withdrawal syndrome. By advising her to take one dose of Elavil, it helps to alleviate the withdrawal symptoms and prevent further complications. Instructing her to contact her doctor ensures proper follow-up and monitoring. Choice A is incorrect because going to the emergency department may not be necessary for this situation. Choice B is incorrect as it does not address the underlying issue of withdrawal from the antidepressant. Choice D is incorrect as it provides a potentially harmful tapering schedule that may not adequately manage withdrawal symptoms.
Question 5 of 5
A patient is being changed from an injectable anticoagulant to an oral anticoagulant. Which anticoagulant does the nurse realize is administered orally?
Correct Answer: B
Rationale: Rationale: 1. Warfarin is administered orally, making it suitable for transitioning from an injectable anticoagulant. 2. Enoxaparin, Bivalirudin, and Dalteparin are injectable anticoagulants, not suitable for oral administration. Summary: Warfarin is the correct choice as it is the only oral anticoagulant among the options. Enoxaparin, Bivalirudin, and Dalteparin are injectable anticoagulants, not suitable for oral administration.
