1. What is one of the therapeutic uses of Valproate?
- A. Suppression of seizure activity
- B. Replacement of hypothyroidism to restore normal hormone balance
- C. Maintenance of blood glucose
- D. Lowering of blood pressure
Correct answer: A
Rationale: Valproate, also known as Valproic acid, is commonly used in medicine for the suppression of seizure activity. It is an anticonvulsant medication that helps manage and prevent seizures in various conditions such as epilepsy. While it is not used for replacing hypothyroidism, maintaining blood glucose levels, or lowering blood pressure, its primary therapeutic use is in managing seizures.
2. A client in an acute care facility is receiving IV Nitroprusside for hypertensive crisis. The nurse should monitor the client for which of the following adverse reactions to this medication?
- A. Intestinal ileus
- B. Neutropenia
- C. Delirium
- D. Hyperthermia
Correct answer: C
Rationale: The correct answer is C: Delirium. When IV Nitroprusside is infused at high dosages, it can lead to thiocyanate toxicity, causing mental status changes such as delirium. It is crucial to monitor the thiocyanate levels to ensure they remain below 10 mg/dL during therapy to prevent adverse effects. Choices A, B, and D are incorrect because IV Nitroprusside is not commonly associated with intestinal ileus, neutropenia, or hyperthermia. Monitoring for delirium is crucial due to the risk of thiocyanate toxicity.
3. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?
- A. Sodium phosphate
- B. Psyllium
- C. Bisacodyl
- D. Polyethylene glycol
Correct answer: A
Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.
4. A client has been on levothyroxine therapy for several months. Which of the following findings indicates a therapeutic response to the medication?
- A. Decrease in level of thyroxine (T4)
- B. Increase in weight
- C. Increase in hours of sleep per night
- D. Decrease in level of thyroid stimulating hormone (TSH)
Correct answer: D
Rationale: A therapeutic response to levothyroxine is indicated by a decrease in the level of TSH. This decrease signifies that the body requires less stimulation to produce thyroid hormone, reflecting a normalization of thyroid function due to the medication's effectiveness. Choices A, B, and C are incorrect as an increase in T4 levels, weight gain, and increased sleep hours are not indicative of a therapeutic response to levothyroxine therapy.
5. A client has a new prescription for Lithium Carbonate. When teaching the client about ways to prevent Lithium toxicity, the client should be advised to do which of the following?
- A. Avoid using acetaminophen for headaches.
- B. Restrict intake of foods rich in sodium.
- C. Decrease fluid intake to less than 1,500 mL daily.
- D. Limit aerobic activity in hot weather.
Correct answer: D
Rationale: The correct answer is to advise the client to limit aerobic activity in hot weather. Aerobic activity in hot weather can lead to excessive sweating, potentially causing sodium and water depletion, which can increase the risk of Lithium toxicity. It is important for clients taking Lithium to maintain adequate hydration and sodium levels to prevent toxicity. Choices A, B, and C are incorrect. Avoiding acetaminophen for headaches is not directly related to Lithium toxicity. Restricting intake of foods rich in sodium is not recommended because adequate sodium levels are necessary to prevent Lithium toxicity. Decreasing fluid intake to less than 1,500 mL daily is also not advisable as adequate hydration is important to prevent Lithium toxicity.
