Question 1 of 5
A client is prescribed with carbamazepine (Tegretol) for the treatment of bipolar disorder. Which of the following laboratory results indicates that the client is experiencing a side effect of this medication?
Correct Answer: A
Rationale: Carbamazepine can cause leukopenia, including neutropenia, as a side effect. A neutrophil count of 1,200/mm3 is below the normal range and indicates a potential adverse effect. Platelet count, uric acid, and SGPT levels are within normal ranges and do not indicate side effects. Therefore, the neutrophil count is the concerning result.
Question 2 of 5
Regarding drugs used in the treatment of status epilepsy:
Correct Answer: D
Rationale: Phenytoin controls status epilepticus via anticonvulsant action, not sedation, so that's false. It precipitates in dextrose, only saline-compatible, making that false. Diazepam's effect is short-lived, not long-lasting, so that's incorrect. Phenobarbitone commonly causes respiratory depression, a true statement, due to CNS suppression. Phenytoin's rate is 50 mg/min max. This side effect limits phenobarbitone's use, requiring ventilatory support in status management.
Question 3 of 5
The nurse is teaching a class for clients about over-the-counter (OTC) medications. The nurse determines that education has been effective when the clients make which statement?
Correct Answer: C
Rationale: Reading OTC labels and seeking clarification from a doctor if unclear ensures safe use, reflecting effective education on responsibility. Always calling the doctor is overly cautious-OTC drugs are for self-management. Pharmacists help, but label-reading is primary. Assuming OTC safety ignores risks like ibuprofen's bleeding potential. Label focus empowers clients, balancing autonomy with safety, a key learning outcome.
Question 4 of 5
Mark the location of the beginning of the plateau phase on this dose-response relationship curve.
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The nurse has completed medication education with the patient who is receiving lithium (Eskalith). What is the priority patient outcome?
Correct Answer: B
Rationale: Lithium toxicity (e.g., tremors, confusion) at narrow therapeutic range (0.6-1.2) is life-threatening-knowing signs (e.g., nausea) and prevention (e.g., hydration) is priority, per safety. Work, ADLs, and mood stability follow but aren't immediate risks. Toxicity awareness saves lives, per education.
