Correct answer: B

Rationale: The correct answer is B. Taking theophylline at bedtime is inappropriate because it can cause insomnia. The medication should be taken early in the morning to avoid disrupting sleep patterns. It is important to follow the healthcare provider's instructions regarding the timing of the medication to achieve optimal therapeutic effects.

2. Oxybutynin chloride (Ditropan XL) is prescribed for a client with neurogenic bladder. Which sign would indicate a possible toxic effect related to this medication?

Other signs of toxicity may include hypotension or hypertension, confusion, tachycardia, a flushed or red face, and signs of respiratory depression.

3. A nurse is monitoring a client receiving lithium carbonate for bipolar disorder. Which finding should the nurse report immediately to the healthcare provider?

Rationale: Persistent vomiting can be a sign of lithium toxicity, which requires immediate medical attention. Increased thirst, fine hand tremors, and frequent urination are common side effects of lithium.

4. A client is receiving morphine sulfate for pain management. Which assessment finding requires immediate action?

Correct answer: C

Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a serious side effect of morphine sulfate that can lead to respiratory compromise and requires immediate intervention. Constipation, drowsiness, and nausea are common side effects of morphine but are not immediately life-threatening compared to respiratory depression. Monitoring and addressing a low respiratory rate are crucial in preventing further respiratory distress or failure.
