Nursing Elites

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 a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?

• A. Apply the patch to the same site each day.
• B. Remove the patch at night.
• C. Cover the patch with a heating pad.
• D. Apply the patch to a hairless area of skin.

Correct answer: D

Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This is important for proper absorption of the medication. Additionally, rotating the patch to different sites each day helps prevent skin irritation and ensures optimal therapeutic effect. Applying the patch to the same site each day can lead to skin irritation or tolerance development. Removing the patch at night is not necessary as the patch is typically worn continuously to provide a consistent level of medication. Covering the patch with a heating pad is contraindicated as it can increase drug absorption, potentially leading to adverse effects.

3. A patient states he experiences anxiety and has panic attacks at least once a week. What might be helpful for this patient?

• A. Phenytoin (Dilantin)
• B. Lithium
• C. Alprazolam (Xanax)
• D. Spironolactone

Correct answer: C

Rationale: Alprazolam (Xanax) is a medication commonly prescribed to treat anxiety disorders and panic attacks. It belongs to the class of medications known as benzodiazepines, which work by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain to produce a calming effect. Phenytoin is an antiepileptic drug, not typically used for anxiety or panic attacks. Lithium is primarily used to treat bipolar disorder, not anxiety. Spironolactone is a diuretic primarily used to treat conditions like high blood pressure and heart failure, not anxiety or panic attacks.

4. A client has a new prescription for Warfarin. Which of the following statements by the client indicates a need for further teaching?

• A. I will avoid eating large amounts of green leafy vegetables.
• B. I will take my medication at the same time every day.
• C. I will increase my intake of foods high in potassium.
• D. I will report any signs of bleeding to my provider.

Correct answer: C

Rationale: The correct answer is C because Warfarin interacts with vitamin K, not potassium. Therefore, the client needs to be cautious with foods high in vitamin K, such as green leafy vegetables, rather than foods high in potassium. Choices A, B, and D are correct statements regarding Warfarin therapy and do not indicate a need for further teaching.

5. A healthcare professional is caring for four clients who have Peptic Ulcer Disease. The healthcare professional should recognize Misoprostol is contraindicated for which of the following clients?

• A. A client who is pregnant
• B. A client who has osteoarthritis
• C. A client who has a kidney stone
• D. A client who has a urinary tract infection

Correct answer: A

Rationale: Misoprostol is contraindicated in pregnancy as it can induce labor and potentially lead to harm to the fetus. Therefore, it should not be used in pregnant clients due to its uterotonic effects. For clients with osteoarthritis, kidney stone, or urinary tract infection, Misoprostol is not contraindicated specifically for these conditions.
