Nursing Elites

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 Lisinopril. Which of the following instructions should the nurse include?

• A. Avoid salt substitutes.
• B. Take this medication at bedtime.
• C. Increase your intake of potassium-rich foods.
• D. Take this medication with food.

Correct answer: A

Rationale: The correct instruction for a client prescribed Lisinopril is to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, hence the importance of avoiding salt substitutes that may contain potassium. Instructing the client to avoid salt substitutes helps prevent potential adverse effects of increased potassium levels.

3. 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.

4. A client is taking Sucralfate PO for Peptic Ulcer Disease and has a new prescription for phenytoin to control seizures. Which of the following instructions should the nurse include?

• A. Take an antacid with the sucralfate.
• B. Take sucralfate with a glass of milk.
• C. Allow a 2-hour interval between these medications.
• D. Chew the sucralfate thoroughly before swallowing.

Correct answer: C

Rationale: Sucralfate can interfere with the absorption of phenytoin. To prevent this interaction, the client should allow a 2-hour interval between taking sucralfate and phenytoin. This timing helps to ensure adequate absorption and effectiveness of both medications without compromising therapeutic outcomes. Choices A, B, and D are incorrect because taking an antacid with sucralfate, taking sucralfate with a glass of milk, and chewing sucralfate thoroughly before swallowing do not address the need for a 2-hour interval between these medications to prevent interference with phenytoin absorption.

5. When assessing a client taking Gemfibrozil, which of the following findings should the nurse identify as an adverse reaction to the medication?

• A. Mental status changes
• B. Tremor
• C. Jaundice
• D. Pneumonia

Correct answer: C

Rationale: Jaundice is an adverse reaction that can occur in clients taking Gemfibrozil due to the potential development of liver impairment. Other symptoms of liver impairment may include anorexia and upper abdominal discomfort. Monitoring for signs of jaundice is crucial to detect and manage adverse effects of the medication promptly. Mental status changes (choice A) are not commonly associated with Gemfibrozil use. Tremor (choice B) is not a typical adverse reaction of Gemfibrozil. Pneumonia (choice D) is not directly linked to Gemfibrozil use but can be a complication in some cases.
