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 being taught about a new prescription for Escitalopram to treat generalized anxiety disorder. Which statement by the client indicates understanding of the teaching?

• A. I should take the medication with food.
• B. I will monitor my blood sugar levels while taking this medication.
• C. I need to discontinue this medication slowly.
• D. I can crush this medication before swallowing.

Correct answer: C

Rationale: The correct answer is C. When discontinuing Escitalopram, the client should taper the medication slowly according to a prescribed dosing schedule to reduce the risk of withdrawal syndrome. Abruptly stopping the medication can lead to withdrawal symptoms, so it is important to follow the healthcare provider's instructions for gradual discontinuation. Choices A, B, and D are incorrect because Escitalopram should not necessarily be taken with food, there is no direct correlation with blood sugar levels, and the medication should not be crushed before swallowing.

3. A healthcare professional is preparing to administer vancomycin to a client. The professional should monitor for which of the following adverse effects?

• A. Nephrotoxicity
• B. Hepatotoxicity
• C. Red Man Syndrome
• D. Diarrhea

Correct answer: C

Rationale: Red Man Syndrome is a common adverse effect of vancomycin characterized by flushing and rash. It is not related to nephrotoxicity, hepatotoxicity, or diarrhea. Monitoring for this reaction allows for prompt intervention to prevent severe complications.

4. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

• A. Four medications decrease the risk of a severe allergic reaction.
• B. Four medications reduce the chance that the bacteria will become resistant.
• C. Four medications reduce the risk of adverse reactions.
• D. Four medications decrease the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: The correct answer is B. When treating tuberculosis, using a combination of medications is crucial to reduce the risk of bacteria developing resistance to any single drug. This approach helps prevent treatment failure and ensures successful treatment outcomes. Choice A is incorrect because the primary purpose of using multiple medications is not related to allergic reactions. Choice C is incorrect as the risk reduction is mainly focused on bacterial resistance rather than adverse reactions. Choice D is not relevant as the purpose of taking multiple medications is not to affect the tuberculin skin test results.

5. A client has a new prescription for Prednisone. Which of the following laboratory values should be monitored by the healthcare provider?

• A. Serum potassium
• B. Serum calcium
• C. Serum sodium
• D. Serum glucose

Correct answer: D

Rationale: When a client is prescribed Prednisone, monitoring serum glucose levels is essential. Prednisone, a corticosteroid, can lead to hyperglycemia. Therefore, regular monitoring of serum glucose helps in detecting and managing any potential hyperglycemic effects of the medication. Monitoring serum potassium, calcium, or sodium is not typically required when a client is on Prednisone unless there are specific risk factors or concerns related to these electrolytes.
