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. What symptoms should a patient taking Omeprazole report to the healthcare provider?

• A. Black, tarry stools
• B. Diarrhea
• C. Abdominal pain
• D. All of the above

Correct answer: D

Rationale: Patients taking Omeprazole should report black, tarry stools, diarrhea, or abdominal pain to the healthcare provider because these symptoms could indicate serious side effects associated with the medication. Black, tarry stools may suggest gastrointestinal bleeding, diarrhea can be a sign of a gastrointestinal infection or adverse drug reaction, and abdominal pain may indicate underlying issues that need attention. Choosing 'All of the above' is the correct answer as all these symptoms are important to report for proper evaluation and management.

3. A client prescribed Isosorbide Mononitrate for chronic stable Angina develops reflex tachycardia. Which of the following medications should the nurse expect to administer?

• A. Furosemide
• B. Captopril
• C. Ranolazine
• D. Metoprolol

Correct answer: D

Rationale: Metoprolol, a beta-adrenergic blocker, is commonly used to treat hypertension and stable angina pectoris. It is often prescribed to decrease heart rate in clients experiencing tachycardia, including those with reflex tachycardia induced by medications like Isosorbide Mononitrate. Furosemide (Choice A) is a diuretic and is not indicated for reflex tachycardia. Captopril (Choice B) is an ACE inhibitor used for hypertension and heart failure, not tachycardia. Ranolazine (Choice C) is used in chronic angina but does not address tachycardia.

4. A healthcare professional is preparing to administer vancomycin 1 g by intermittent IV bolus. Available is vancomycin 1 g in 100 mL of dextrose 5% in water (D5W) to infuse over 45 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver?

• A. 22 gtt/min
• B. 24 gtt/min
• C. 20 gtt/min
• D. 18 gtt/min

Correct answer: A

Rationale: To determine the flow rate in drops per minute (gtt/min), you can use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, it would be (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Therefore, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min. Choice B, 24 gtt/min, is incorrect as it results from a miscalculation. Choices C and D, 20 gtt/min and 18 gtt/min respectively, are also incorrect calculations based on the given parameters.

5. Which of the following is commonly used to treat migraine headaches?

• A. Beta-blockers
• B. Cholinesterase Inhibitors
• C. ACE inhibitors
• D. Anti-epileptic drugs (AEDs)

Correct answer: D

Rationale: Anti-epileptic drugs (AEDs) are often used in the management of migraine headaches due to their ability to help prevent or reduce the frequency and intensity of migraines. They work by stabilizing electrical activity in the brain, which can help in controlling migraine symptoms. While beta-blockers are also sometimes used in migraine prevention, anti-epileptic drugs are more commonly associated with migraine treatment. Cholinesterase Inhibitors are not typically used for migraine headaches, as they are more commonly associated with conditions like Alzheimer's disease. ACE inhibitors are a type of medication used to treat conditions like high blood pressure and heart failure, but they are not a first-line treatment for migraines.
