Question 1 of 5
The nurse is providing medication teaching to a client with bipolar disorder who receives a prescription for lithium carbonate. Which instruction should the nurse emphasize with the client?
Correct Answer: B
Rationale: Adequate fluid intake (1,500-3,000 mL/day) prevents dehydration, which can elevate lithium levels and risk toxicity. Food intake, weight reporting, or fliers are less critical to lithium safety.
Question 2 of 5
The nurse is administering the muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention should the nurse implement?
Correct Answer: A
Rationale: Baclofen causes dizziness and weakness, increasing fall risk. Advising slow, cautious movement prevents injuries. Intake/output, stopping antispasmodics, or frequent strength checks are less relevant.
Question 3 of 5
The nurse administers the initial dose of cefoxitin to a client whose medical record indicates an allergy to penicillin. Which finding is most important for the nurse to report to the healthcare provider?
Correct Answer: B
Rationale: Pruritis and rash suggest a possible allergic reaction to cefoxitin, a cephalosporin, due to cross-reactivity with penicillin. This requires immediate reporting. Renal output, GI symptoms, and vaginal discharge are less specific to allergic responses.
Question 4 of 5
The nurse administers naloxone to a client with opioid-induced respiratory depression. One hour later, nursing assessment reveals that the client has a respiratory rate of 4 breaths/minute, oxygen saturation of 75%, and is unable to be aroused. Which action should the nurse implement?
Correct Answer: B
Rationale: Persistent respiratory depression (4 breaths/min, 75% saturation) indicates ongoing opioid toxicity. Naloxone’s short half-life may require a second dose to reverse opioid effects. Chest tubes, GCS, or CPR do not address the opioid-related cause.
Question 5 of 5
The nurse is teaching a client who has been diagnosed with HIV about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Antiretrovirals reduce viral load and transmission risk but do not fully prevent HIV transmission. Safe practices are needed. Other statements are accurate regarding HIV management.
