1. What is the therapeutic use of Phenytoin?
- A. Replacement in hypothyroidism to restore normal hormonal balance
- B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
- C. Diminished seizure activity, termination of ventricular arrhythmias
- D. Prevention of thrombus formation, prevention of extension of existing thrombi
Correct answer: C
Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.
2. Why should the nitrate patch be off for 8 hours per day?
- A. “There is no reason to take the patch off each day.”
- B. “The patch can be addictive; leaving it off reduces the addiction.”
- C. “You should only leave the patch off for 15 minutes.”
- D. “Leaving the patch off for 8 hours per day helps to delay the development of tolerance.”
Correct answer: D
Rationale: Removing the nitrate patch for 8 hours each day is essential to prevent the body from developing tolerance to the medication. By allowing the body to have a drug-free period, the effectiveness of the medication is maintained over time. This practice helps in ensuring that the nitrate patch continues to provide its intended therapeutic effects without diminishing its efficacy. Therefore, it is important for the client to adhere to the prescribed schedule of removing the patch for 8 hours daily to optimize the treatment outcomes.
3. A client has been prescribed Prednisone for an inflammatory condition and is receiving discharge teaching from a nurse. Which of the following instructions should the nurse include?
- A. Take this medication on an empty stomach.
- B. Avoid alcohol while taking this medication.
- C. Monitor your blood pressure regularly.
- D. Take this medication in the morning to prevent insomnia.
Correct answer: D
Rationale: The correct answer is to take Prednisone in the morning to prevent insomnia. Prednisone can cause insomnia as a side effect, so taking it in the morning can help minimize this issue. It is important to follow the healthcare provider's instructions regarding the timing of Prednisone administration to optimize its effectiveness and minimize adverse effects.
4. When completing a nursing history for a client taking Simvastatin, which of the following disorders should the nurse identify as a contraindication to adding Ezetimibe to the client's medications?
- A. History of severe constipation
- B. History of hypertension
- C. Active hepatitis C
- D. Type 2 diabetes mellitus
Correct answer: C
Rationale: Ezetimibe is contraindicated in clients with active moderate-to-severe liver disorders, particularly if they are already on a statin like simvastatin. Hepatitis C is a liver condition that can be exacerbated by Ezetimibe, leading to potential complications. Therefore, the nurse should identify active hepatitis C as a contraindication to adding Ezetimibe to the client's medications. Choices A, B, and D are incorrect because they are not directly related to the contraindication of Ezetimibe in clients taking Simvastatin.
5. How should the oral form of albuterol be taken?
- A. Administer with meals to minimize gastric irritation
- B. Administer before meals with water
- C. Administer after meals with water
- D. Administer in the morning with milk
Correct answer: A
Rationale: The correct way to take oral albuterol is with meals to minimize gastric irritation. Taking it with food can help reduce the risk of stomach upset that may occur when the medication is taken on an empty stomach. This approach can improve tolerability and adherence to the treatment regimen. Choices B, C, and D are incorrect because taking albuterol before meals, after meals, or in the morning with milk does not address the issue of minimizing gastric irritation, which is a common side effect of the medication.
