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 has a new prescription for Enalapril. Which of the following adverse effects should the nurse monitor?

• A. Dry cough
• B. Weight gain
• C. Diarrhea
• D. Nausea

Correct answer: A

Rationale: The correct answer is A: Dry cough. A persistent dry cough is a common adverse effect of Enalapril, an ACE inhibitor. Enalapril can cause the accumulation of bradykinin, leading to cough. Monitoring for a persistent dry cough is crucial as it may indicate the need for further evaluation and possible medication adjustment. Choices B, C, and D are not typically associated with Enalapril use and are less likely to be monitored as adverse effects.

3. A client is taking Propylthiouracil. For which of the following adverse effects of this medication should the nurse monitor?

• A. Bradycardia
• B. Insomnia
• C. Heat intolerance
• D. Weight loss

Correct answer: A

Rationale: Propylthiouracil is a medication used to treat hyperthyroidism. One of the adverse effects of Propylthiouracil is bradycardia, which is a slower than normal heart rate. Since the medication works by decreasing thyroid hormone production, it can lead to hypothyroidism as a side effect, causing bradycardia. Therefore, the nurse should monitor the client for signs and symptoms of bradycardia while taking Propylthiouracil. Choices B, C, and D are incorrect because insomnia, heat intolerance, and weight loss are not typically associated adverse effects of Propylthiouracil.

4. A client with cirrhosis is about to receive a dose of lactulose. The client questions the need for the medication, stating they are not constipated. The nurse should explain that lactulose is used in cirrhosis to reduce levels of which component in the bloodstream?

• A. Glucose
• B. Ammonia
• C. Potassium
• D. Bicarbonate

Correct answer: B

Rationale: Lactulose is administered to clients with cirrhosis to lower blood ammonia levels, thus aiding in the prevention of hepatic encephalopathy. Elevated ammonia levels in cirrhosis can lead to cognitive impairment and hepatic encephalopathy. Therefore, the correct answer is B (Ammonia). Glucose (Choice A) is not the component targeted by lactulose in cirrhosis. Potassium (Choice C) and Bicarbonate (Choice D) are not directly affected by lactulose administration in cirrhosis.

5. A client has been prescribed a new oral hypoglycemic agent for diabetes. Which of the following statements by the client indicates a need for further teaching?

• A. I will take this medication with my evening snack.
• B. I will monitor my blood sugar levels before each meal.
• C. I will take this medication as soon as I wake up.
• D. I will follow my exercise plan as usual.

Correct answer: A

Rationale: Taking an oral hypoglycemic agent with an evening snack may lead to hypoglycemia during the night. It is important to follow the prescribed timing for medication administration to maintain blood sugar levels within the target range. The medication is usually taken before meals to help control postprandial blood glucose levels effectively. Choice B is correct as monitoring blood sugar levels before each meal is a good practice. Choice C is incorrect as taking the medication upon waking up may align with certain oral hypoglycemic agents' dosing schedules. Choice D is also correct as regular exercise is an important part of managing diabetes.
