1. A client has Diabetes Mellitus, Pulmonary Tuberculosis, and a new prescription for Isoniazid. Which of the following supplements should the nurse expect to administer to prevent an adverse effect of INH?
- A. Ascorbic acid
- B. Pyridoxine
- C. Folic acid
- D. Cyanocobalamin
Correct answer: B
Rationale: Pyridoxine is administered with Isoniazid to prevent peripheral neuropathy, a common adverse effect of the drug. It is essential to provide this supplement to the client to minimize the risk of developing this adverse effect. Ascorbic acid (Vitamin C) is not typically given to prevent INH adverse effects. Folic acid and Cyanocobalamin are not commonly administered with INH for this purpose.
2. A client has a new prescription for Metronidazole to treat an infection. Which of the following instructions should the nurse include?
- A. Avoid alcohol while taking this medication.
- B. Take this medication on an empty stomach.
- C. Increase your intake of dairy products while taking this medication.
- D. Avoid direct sunlight while taking this medication.
Correct answer: A
Rationale: The correct instruction is to avoid alcohol while taking Metronidazole. This is crucial to prevent a disulfiram-like reaction, which can result in severe nausea and vomiting. Alcohol should be avoided for at least 48 hours after completing the medication course as well. Choice B is incorrect because Metronidazole can be taken with food to reduce gastrointestinal side effects. Choice C is incorrect because there is no need to increase dairy product intake while on Metronidazole. Choice D is incorrect because there is no specific instruction to avoid direct sunlight while taking this medication.
3. Which of the following is commonly used to treat migraine headaches?
- A. Beta-blockers
- B. Cholinesterase Inhibitors
- C. ACE inhibitors
- D. Anti-epileptic drugs (AEDs)
Correct answer: D
Rationale: Anti-epileptic drugs (AEDs) are often used in the management of migraine headaches due to their ability to help prevent or reduce the frequency and intensity of migraines. They work by stabilizing electrical activity in the brain, which can help in controlling migraine symptoms. While beta-blockers are also sometimes used in migraine prevention, anti-epileptic drugs are more commonly associated with migraine treatment. Cholinesterase Inhibitors are not typically used for migraine headaches, as they are more commonly associated with conditions like Alzheimer's disease. ACE inhibitors are a type of medication used to treat conditions like high blood pressure and heart failure, but they are not a first-line treatment for migraines.
4. When administering an Antiulcer Agent, you should be more cautious when administering it to:
- A. A healthy 27-year-old patient
- B. Patient with renal failure
- C. Elderly patients
- D. Choices B & C
Correct answer: D
Rationale: When administering an antiulcer agent, caution is warranted in patients with renal failure due to the potential impact on drug metabolism and excretion. Additionally, elderly patients may be more susceptible to adverse effects from antiulcer agents due to age-related physiological changes. Therefore, it is important to be more cautious when administering antiulcer agents to patients with renal failure and elderly patients. Choice A, a healthy 27-year-old patient, would typically not require as much caution compared to patients with renal failure or elderly patients when administering antiulcer agents. Therefore, choices B & C are the correct options for increased caution.
5. What is the therapeutic class of Valproate?
- A. Anticoagulant
- B. Antianxiety, benzodiazepines
- C. Anticonvulsant, vascular headache suppressant
- D. Mood stabilizer
Correct answer: C
Rationale: Valproate belongs to the therapeutic class of anticonvulsants. It is primarily used to manage seizures but is also effective in treating vascular headaches. Therefore, it is not classified as an anticoagulant, antianxiety medication, or mood stabilizer. Option A, anticoagulant, is incorrect as valproate does not have anticoagulant properties. Option B, antianxiety benzodiazepines, is incorrect as valproate is not primarily used to treat anxiety disorders with benzodiazepines. Option D, mood stabilizer, is incorrect as valproate is not classified as a mood stabilizer, although it can be used in some cases for mood disorders, its primary therapeutic class is anticonvulsant.
