1. What is the therapeutic classification of Furosemide?

A. Antidiuretics
B. Diuretics
C. Anticonvulsants
D. Antidotes

Correct answer: B

Rationale: Furosemide is classified therapeutically as a diuretic. Diuretics are medications used to promote diuresis, which helps the body get rid of excess salt and water. Furosemide is commonly prescribed to treat conditions such as fluid retention and swelling (edema) associated with congestive heart failure, liver disease, or kidney disorders. Choice A, Antidiuretics, is incorrect as Furosemide acts as a diuretic, promoting the production of urine. Choice C, Anticonvulsants, is also incorrect as Furosemide is not used to treat seizures. Choice D, Antidotes, is incorrect as Furosemide is not an antidote but rather a medication used to treat conditions related to fluid retention.

2. A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?

A. A headache indicates a serious allergic reaction to nitroglycerin.
B. The client will not have a headache if the nitroglycerin is taken with a high-fat meal.
C. Nitroglycerin does not cause a headache.
D. The most common side effect of nitroglycerin is a headache.

Correct answer: D

Rationale: Nitroglycerin is known to cause headaches as a common side effect due to its vasodilatory properties. It dilates blood vessels, which can lead to headaches. While a headache can indicate other serious conditions, the most common association with nitroglycerin use is a headache. It is crucial for the nurse to recognize this side effect and provide appropriate education and support to the client.

3. A healthcare professional is providing discharge instructions to a client who has a new prescription for Furosemide. Which of the following instructions should the healthcare professional include?

A. Take the medication with breakfast.
B. Increase intake of foods high in potassium.
C. Avoid prolonged sun exposure.
D. Limit sodium intake.

Correct answer: B

Rationale: The correct answer is B: 'Increase intake of foods high in potassium.' Furosemide, a loop diuretic, can cause potassium depletion. The healthcare professional should instruct the client to increase the intake of foods high in potassium to prevent hypokalemia, a potential side effect of Furosemide therapy. Choice A is incorrect as Furosemide is usually recommended to be taken in the morning to prevent nocturia. Choice C is unrelated to the side effects of Furosemide. Choice D, while important for overall health, is not directly related to the side effects of Furosemide.

4. A client is receiving treatment with bevacizumab. Which of the following findings should the nurse monitor?

A. Hypertension
B. Hypokalemia
C. Hyperglycemia
D. Hypocalcemia

Correct answer: A

Rationale: Correct Answer: A. Bevacizumab is known to cause hypertension as a common adverse effect. The nurse should closely monitor the client's blood pressure to detect and manage this potential side effect promptly. Choice B, hypokalemia, is not typically associated with bevacizumab treatment. Choice C, hyperglycemia, is not a common adverse effect of bevacizumab. Choice D, hypocalcemia, is not a recognized side effect of bevacizumab.

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.
