Question 1 of 5
The patient receives imipramine (Tofranil) as treatment for depression. He is admitted to the emergency department following an intentional overdose of this medication. What will the priority assessment by the nurse include?
Correct Answer: A
Rationale: Imipramine, a TCA, in overdose risks cardiac toxicity-arrhythmias (e.g., QRS widening)-per toxicology, making heart status priority. Liver and renal function matter but are secondary-cardiac collapse kills faster. Neurological signs (e.g., seizures) follow but heart trumps. Cardiac focus saves lives, per protocol.
Question 2 of 5
The patient with schizophrenia is sitting quietly in a chair. The patient does not respond much to what is happening and has a lack of interest in the environment. How does the nurse interpret this assessment?
Correct Answer: D
Rationale: Schizophrenia involves positive symptoms (e.g., hallucinations) and negative symptoms (e.g., apathy, withdrawal). The patient's quiet demeanor, lack of responsiveness, and disinterest align with negative symptoms, which diminish normal behaviors like motivation or social engagement. Depression might present similarly but isn't assumed without further evidence like sadness or hopelessness. Hearing voices suggests positive symptoms, but the scenario lacks indicators like distractedness. Positive symptoms involve added behaviors (e.g., delusions), not subtraction, as seen here. The nurse interprets this based on schizophrenia's symptomology, recognizing negative symptoms as a core feature, making choice D the most accurate clinical interpretation.
Question 3 of 5
A nurse is instructing a client regarding carbidopa-levodopa (Sinemet) for the treatment of Parkinson’s disease. The nurse tells the client which of the following indicates an overdose of the medication?
Correct Answer: A
Rationale: An overdose of carbidopa-levodopa (Sinemet) can cause excessive dopaminergic stimulation, leading to dyskinesias or difficulty performing voluntary movements. Increased blood pressure, decreased appetite, and black tarry stools are not typical signs of overdose. Therefore, difficulty with voluntary movement is the correct indicator of overdose.
Question 4 of 5
The following drugs produce a prolonged action due to enterohepatic recirculation:
Correct Answer: A
Rationale: Diazepam undergoes enterohepatic recirculation, contributing to its prolonged duration of action.
Question 5 of 5
A 38-year-old man who is a chronic coffee drinker for 20 years drinks approximately seven cups of coffee per day. He suddenly decides to stop drinking coffee. Which of the following effects may he exhibit?
Correct Answer: A
Rationale: Chronic high-dose caffeine cessation causes withdrawal. Lethargy -reflects reduced adenosine blockade, leading to fatigue. Migraine , nausea , and vomiting (E) may occur, but lethargy is most common. Tinnitus isn't typical. His 20-year habit predicts this CNS depression.
