1. What is the therapeutic action of Phenytoin?

• A. Antidiabetic
• B. Anticonvulsant
• C. Mood stabilizer
• D. Antianxiety agent

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.

2. A staff educator is reviewing medication dosages and factors that influence medication metabolism with a group of nurses at an in-service presentation. Which of the following factors should the educator include as a reason to administer lower medication dosages? (Select all that apply.)

• A. Increased renal secretion
• B. Increased medication-metabolizing enzymes
• C. Liver failure
• D. Peripheral vascular disease

Correct answer: C

Rationale: Liver failure impairs metabolism, leading to increased medication concentrations. When liver function is compromised, lower dosages are necessary to prevent adverse effects. Increased renal secretion is not a reason for lower medication dosages, as it primarily affects excretion rather than metabolism. Increased medication-metabolizing enzymes would usually require higher dosages to achieve the desired effect. Peripheral vascular disease does not directly impact medication metabolism or dosage requirements.

• A. I will need to get my blood drawn periodically while on this medication.'
• B. I should stop taking this medication if I develop a rash.'
• C. I will need to limit my alcohol intake to no more than one drink per week.'
• D. I should self-administer this medication subcutaneously into the muscle.'

Correct answer: A

4. Which of the following is not directly related to drug toxicity of Nitroglycerin?

• A. Headaches
• B. Tachycardia
• C. Dizziness
• D. Projectile vomiting

Correct answer: D

Rationale: Headaches, tachycardia, and dizziness are common side effects of nitroglycerin due to its vasodilatory properties. Projectile vomiting is not typically associated with nitroglycerin toxicity, making it the correct answer. Therefore, option D is the correct choice.

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

• A. Take this medication on an empty stomach.
• B. Take this medication in the morning.
• C. Take this medication at bedtime.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct instruction for taking Lovastatin is to take it at bedtime. Cholesterol production in the liver is highest at night, so taking Lovastatin at bedtime aligns with the body's natural rhythm and maximizes its effectiveness.
