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. A client is withdrawing from alcohol and has a new prescription for Propranolol. Which of the following information should be included in the teaching?
- A. Increases the risk for seizure activity.
- B. Provides a form of aversion therapy.
- C. Decreases cravings.
- D. Results in mild hypertension.
Correct answer: C
Rationale: The correct answer is C: 'Decreases cravings.' Propranolol is commonly used as an adjunct medication during alcohol withdrawal to help reduce cravings for alcohol. It does not increase the risk for seizure activity, provide aversion therapy, or result in mild hypertension. By decreasing cravings, Propranolol can support the client in managing alcohol withdrawal symptoms and promoting abstinence. Therefore, it is important to educate the client on how Propranolol can help them cope with alcohol cravings effectively.
3. A client has a new prescription for Buspirone to treat Anxiety. Which of the following information should the nurse include?
- A. Take this medication with food.
- B. Expect optimal therapeutic effects within 24 hours.
- C. Take this medication daily for anxiety.
- D. This medication has a low risk for dependency.
Correct answer: D
Rationale: The nurse should educate the client that Buspirone has a low risk for physical or psychological dependence or tolerance. This information is crucial for the client to understand the medication's safety profile and potential risks associated with long-term use.
4. A client has a new prescription for Atorvastatin. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid drinking grapefruit juice.
- C. Take this medication in the morning.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct answer is B: 'Avoid drinking grapefruit juice.' Grapefruit juice can increase the blood levels of Atorvastatin by inhibiting its metabolism in the body, leading to a higher risk of adverse effects, such as muscle pain and liver damage. Therefore, it is important for the client to avoid consuming grapefruit juice while taking Atorvastatin. Choices A, C, and D are incorrect because Atorvastatin can be taken with or without food, at any time of the day, and there is no specific need to increase potassium-rich foods while on this medication.
5. A client with asthma has a new prescription for inhaled beclomethasone. Which of the following instructions should the nurse provide?
- A. Check the pulse after using the inhaler.
- B. Take the medication with food.
- C. Rinse the mouth after using the inhaler.
- D. Reduce caffeine consumption.
Correct answer: C
Rationale: The correct answer is C: 'Rinse the mouth after using the inhaler.' Rinsing the mouth after using inhaled beclomethasone is crucial to prevent fungal overgrowth in the mouth, a common side effect of corticosteroid inhalers. Checking the pulse after using the inhaler (Choice A) is not directly related to the use of beclomethasone. Taking the medication with food (Choice B) is not a specific instruction for inhaled beclomethasone. While reducing caffeine consumption (Choice D) can be beneficial for some health conditions, it is not a specific instruction related to using inhaled beclomethasone.
