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. Which of the following is not an effect of the drug isoflurane?

• A. Elevated lipid levels
• B. Nausea
• C. Increased blood flow to the brain
• D. Decreased respiratory function

Correct answer: A

Rationale: Isoflurane is not known to cause elevated lipid levels. Common effects of isoflurane include nausea, increased blood flow to the brain, and decreased respiratory function. Elevated lipid levels are not typically associated with the administration of isoflurane, making choice A the correct answer.

3. A client has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect decreased urination within the first few days.
• D. Avoid foods high in potassium.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Hydrochlorothiazide is a diuretic that can lead to hypokalemia by increasing potassium excretion. Therefore, instructing the client to increase their intake of potassium-rich foods is essential to prevent electrolyte imbalances and support overall health. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning is not directly related to the medication's mechanism of action. Expecting decreased urination within the first few days is not accurate as the medication is a diuretic that typically increases urination. Also, advising the client to avoid foods high in potassium would not be suitable, as increasing potassium-rich foods is necessary to counteract potential potassium depletion caused by Hydrochlorothiazide.

4. A drug ending in the suffix (pril) is considered a ______.

• A. H
• B. ACE inhibitor
• C. Antifungal
• D. Beta agonist

Correct answer: B

Rationale: Drugs with names ending in -pril are classified as angiotensin-converting enzyme (ACE) inhibitors. These medications are commonly used to manage conditions like high blood pressure, heart failure, and diabetic kidney disease by blocking the conversion of angiotensin I to angiotensin II, leading to vasodilation and decreased blood pressure.

5. While assessing a client taking Amiodarone to treat Atrial Fibrillation, which of the following findings is indicative of Amiodarone toxicity?

• A. Light yellow urine
• B. Report of tinnitus
• C. Productive cough
• D. Blue-gray skin discoloration

Correct answer: C

Rationale: Productive cough can indicate pulmonary toxicity, which is a known adverse effect of Amiodarone. Clients on Amiodarone should be monitored for signs of pulmonary toxicity such as cough, dyspnea, and chest pain. This is important to detect early and prevent serious complications. The other options are not typically associated with Amiodarone toxicity. Light yellow urine is not a common sign, tinnitus is more related to ear problems, and blue-gray skin discoloration is not a recognized symptom of Amiodarone toxicity.
