1. In an acute mental health facility, a patient experiencing opioid withdrawal has a new prescription for Clonidine. What action should the nurse identify as the priority?
- A. Administer the Clonidine as prescribed.
- B. Provide ice chips to the patient.
- C. Educate the patient on Clonidine's effects.
- D. Obtain baseline vital signs.
Correct answer: D
Rationale: In this scenario, the priority action for the nurse is to obtain baseline vital signs. This is essential for establishing a baseline assessment, especially for a patient undergoing opioid withdrawal and starting a new medication like Clonidine. Monitoring vital signs is crucial for evaluating the patient's response to treatment and detecting any potential complications early on. Administering the medication, providing ice chips, and educating the patient on Clonidine's effects are important tasks but obtaining baseline vital signs takes precedence to ensure the patient's safety and proper management.
2. What should you assess for in a patient who is on Valproate?
- A. Suicidal thoughts
- B. Monitor for seizures
- C. Bipolar disorder
- D. Migraines
Correct answer: A
Rationale: The correct answer is A: Suicidal thoughts. When a patient is prescribed Valproate, it is crucial to assess for suicidal thoughts as it is a serious side effect associated with this medication. Valproate has been linked to an increased risk of suicidal ideation and behavior, particularly in patients with epilepsy or bipolar disorder. Monitoring for signs of depression or changes in behavior is essential to ensure patient safety and well-being. Choices B, C, and D are incorrect because while monitoring for seizures, managing bipolar disorder, and treating migraines are also important considerations when a patient is on Valproate, assessing for suicidal thoughts takes priority due to the serious nature of this potential side effect.
3. A healthcare professional is caring for an older adult client who has a new prescription for Digoxin and takes multiple other medications. Which of the following medications, when used concurrently with Digoxin, places the client at risk for Digoxin toxicity?
- A. Phenytoin
- B. Verapamil
- C. Warfarin
- D. Aluminum hydroxide
Correct answer: B
Rationale: Verapamil, a calcium-channel blocker, can increase digoxin levels, leading to Digoxin toxicity. When these medications are used together, the client is at an increased risk. Phenytoin (Choice A) does not significantly impact digoxin levels. Warfarin (Choice C) and aluminum hydroxide (Choice D) do not directly increase the risk of Digoxin toxicity. Therefore, the correct choice is Verapamil (Choice B) due to its potential to raise digoxin levels and cause toxicity.
4. A client with peptic ulcer disease is prescribed sucralfate. Which of the following instructions should the nurse include?
- A. Take sucralfate with meals.
- B. Take sucralfate 1 hr before meals.
- C. Take sucralfate with antacids.
- D. Take sucralfate 2 hours after meals.
Correct answer: B
Rationale: The correct instruction for taking sucralfate is 1 hour before meals. This timing allows sucralfate to effectively coat the stomach lining and provide a protective barrier against gastric acid, helping to prevent ulcers.
5. Which of the following is the antidote for benzodiazepine toxicity?
- A. Flumazenil
- B. Methylene blue
- C. Deferoxamine
- D. Alkalinize urine
Correct answer: A
Rationale: Flumazenil is the specific antidote for benzodiazepine toxicity. It acts as a competitive antagonist at the benzodiazepine binding site on the GABA receptor, reversing the sedative effects of benzodiazepines. Administration of flumazenil is indicated in cases of benzodiazepine overdose or toxicity to rapidly reverse the central nervous system depression caused by these drugs. It is important to note that flumazenil should be used cautiously in patients with a history of seizures or those who are physically dependent on benzodiazepines, as it can precipitate withdrawal symptoms or seizures.
