1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. A client has a new prescription for Filgrastim to treat neutropenia. Which of the following statements should the nurse include?

• A. This medication will help increase your white blood cell count.
• B. This medication will help reduce your risk of infection.
• C. This medication will help improve your red blood cell count.
• D. This medication will help increase your platelet count.

Correct answer: A

Rationale: The correct statement the nurse should include is that 'This medication will help increase your white blood cell count.' Filgrastim is a medication used to stimulate the production of white blood cells, specifically neutrophils, to increase the white blood cell count. This increase in white blood cells helps reduce the risk of infections in clients with neutropenia. Choices B, C, and D are incorrect because Filgrastim specifically targets white blood cells, not red blood cells or platelets.

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

• A. Drink 2 liters of water daily.
• B. Avoid taking the medication on an empty stomach.
• C. Limit vitamin C intake while taking this medication.
• D. Take an iron supplement while on this medication.

Correct answer: A

Rationale: The correct instruction for a client prescribed allopurinol is to drink 2 liters of water daily. This helps reduce the risk of kidney stones, a potential side effect of allopurinol use. Adequate hydration is essential to prevent kidney stone formation and maintain kidney function while taking this medication.

4. A client is being taught about a new prescription for Escitalopram to treat generalized anxiety disorder. Which statement by the client indicates understanding of the teaching?

• A. I should take the medication with food.
• B. I will monitor my blood sugar levels while taking this medication.
• C. I need to discontinue this medication slowly.
• D. I can crush this medication before swallowing.

Correct answer: C

Rationale: The correct answer is C. When discontinuing Escitalopram, the client should taper the medication slowly according to a prescribed dosing schedule to reduce the risk of withdrawal syndrome. Abruptly stopping the medication can lead to withdrawal symptoms, so it is important to follow the healthcare provider's instructions for gradual discontinuation. Choices A, B, and D are incorrect because Escitalopram should not necessarily be taken with food, there is no direct correlation with blood sugar levels, and the medication should not be crushed before swallowing.

5. A client has a new prescription for Warfarin. Which of the following herbal supplements should the client be instructed to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by affecting its metabolism. Echinacea, garlic, and ginseng are also known to interact with Warfarin, either by increasing the risk of bleeding or altering its anticoagulant effects. However, St. John's wort is particularly significant due to its potent enzyme-inducing properties that can lead to subtherapeutic levels of Warfarin, potentially increasing the risk of blood clots.
