1. When using Nitroglycerine (transdermal), how many hours should you be nitrate-free each day?

• A. 1-2 hours
• B. 5-10 hours
• C. 3-4 hours
• D. 10-12 hours

Correct answer: D

Rationale: When using Nitroglycerine (transdermal), it should be applied for 10-12 hours per day to ensure its effectiveness. A nitrate-free period within the day is essential to prevent the development of tolerance to the medication.

2. A healthcare professional in a provider's office is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?

• A. Calcium 9.2 mg/dL
• B. Calcium 10.3 mg/dL
• C. Potassium 3.4 mEq/L
• D. Potassium 4.8 mEq/L

Correct answer: C

Rationale: The correct answer is C: Potassium 3.4 mEq/L. Potassium 3.4 mEq/L is below the expected reference range and puts a client at risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, especially in older clients taking Digoxin, as potassium plays a crucial role in the heart's electrical activity. Choices A and B are related to calcium levels, which do not directly increase the risk of Digoxin toxicity. Choice D, Potassium 4.8 mEq/L, is within the expected reference range and would not increase the risk of Digoxin toxicity.

3. Which of the following is classified as a class IA Sodium Channel blocker?

• A. Quinidine
• B. Disopyramide
• C. Aminodarone
• D. Propafenone

Correct answer: A

Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.

4. A client has a new prescription for Propranolol. Which of the following findings should the healthcare provider identify as a contraindication to this medication?

• A. Asthma
• B. Diabetes mellitus
• C. Hypertension
• D. Glaucoma

Correct answer: A

Rationale: Propranolol is a non-selective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with asthma. Asthma is a contraindication for Propranolol due to the potential of worsening bronchoconstriction and causing respiratory distress in individuals with this condition. Diabetes mellitus, hypertension, and glaucoma are not contraindications for Propranolol.

5. A drug ending in the suffix (tidine) is considered a ______.

• A. Antidepressant
• B. Protease inhibitor
• C. Beta antagonist
• D. H antagonist

Correct answer: D

Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.
