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 is being taught by a healthcare professional about preventing Otitis Externa. Which of the following instructions should the healthcare professional include?

• A. Clean the ear with a cotton-tipped swab daily
• B. Place earplugs in the ears when sleeping at night
• C. Use a cool water irrigation solution to remove earwax
• D. Tip the head to the side to remove water from the ears after showering

Correct answer: D

Rationale: To prevent Otitis Externa, it is important to remove water from the ears after showering or swimming. This helps reduce the risk of moisture buildup in the ear canal, which can lead to infection. Cleaning the ear with a cotton-tipped swab daily can actually increase the risk of injury or infection. Placing earplugs in the ears when sleeping at night may trap moisture and promote bacterial growth. Using a cool water irrigation solution to remove earwax is not recommended as it can disrupt the natural balance of the ear canal.

3. When educating a client who has a new prescription for Hydrochlorothiazide, which of the following statements should the nurse include?

• A. Take this medication in the morning.
• B. You may need to increase your intake of potassium.
• C. This medication may cause drowsiness.
• D. Avoid consuming grapefruit.

Correct answer: B

Rationale: The correct statement to include when educating a client with a new prescription for Hydrochlorothiazide is that they may need to increase their intake of potassium. Hydrochlorothiazide is a thiazide diuretic that can lead to potassium loss. Monitoring potassium levels and increasing potassium intake if necessary can help prevent complications associated with hypokalemia. Option A is not directly related to the medication's specific instructions. Option C is incorrect as Hydrochlorothiazide typically does not cause drowsiness. Option D is unrelated, as there is no interaction between Hydrochlorothiazide and grapefruit.

4. A client has a new prescription for Enfuvirtide to treat HIV infection. The nurse should monitor the client for which of the following adverse reactions?

• A. Bone marrow suppression
• B. Pancreatitis
• C. Pancreatitis
• D. Bone marrow suppression

Correct answer: D

Rationale: While bone marrow suppression is not typically associated with Enfuvirtide, a more relevant concern is the risk of severe allergic reactions such as anaphylaxis. Enfuvirtide, an HIV fusion inhibitor, can cause local injection site reactions and systemic allergic responses. Monitoring for signs of allergic reactions, such as rash, fever, and difficulty breathing, is crucial to ensure the client's safety.

5. A client has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?

• A. Crushing the medication might cause you to have a stomachache or indigestion.
• B. Crushing the medication is a good idea, and I can mix it in some ice cream for you.
• C. Crushing the medication would release all the medication at once, rather than over time.
• D. Crushing is unsafe, as it destroys the ingredients in the medication.

Correct answer: A

Rationale: Crushing an enteric-coated medication can cause it to break down in the stomach instead of the intestines, potentially leading to gastrointestinal distress like stomachache or indigestion. It is important to take enteric-coated medications whole to ensure they are properly absorbed in the intestines and to prevent irritation to the stomach.
