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 healthcare provider is providing discharge instructions to a client who is prescribed Prednisone. Which of the following dietary instructions should the healthcare provider include?

• A. Increase your intake of potassium-rich foods.
• B. Increase your intake of dairy products.
• C. Avoid foods high in vitamin K.
• D. Decrease your intake of protein.

Correct answer: A

Rationale: The correct answer is to increase the intake of potassium-rich foods (Choice A). Prednisone can cause potassium depletion, so clients should increase their intake of foods such as bananas, oranges, and spinach. Potassium-rich foods help maintain electrolyte balance and prevent complications associated with low potassium levels, such as muscle weakness and irregular heartbeats. Choices B, C, and D are incorrect because increasing dairy products (Choice B) or avoiding foods high in vitamin K (Choice C) are not specifically related to Prednisone therapy. Decreasing protein intake (Choice D) is also not necessary in this case.

3. A client has a new prescription for Phenelzine for the treatment of depression. Which of the following indicates that the client has developed an adverse effect of this medication?

• A. Orthostatic hypotension
• B. Hearing loss
• C. Gastrointestinal bleeding
• D. Weight loss

Correct answer: A

Rationale: Orthostatic hypotension is a known adverse effect of MAOIs, such as Phenelzine. It is characterized by a drop in blood pressure upon standing, which can lead to dizziness or fainting. Monitoring for orthostatic hypotension is crucial when administering MAOIs to prevent potential complications. Hearing loss (Choice B) is not a typical adverse effect associated with Phenelzine. Gastrointestinal bleeding (Choice C) is more commonly linked to NSAIDs or anticoagulants. Weight loss (Choice D) is not a typical adverse effect of Phenelzine and is more likely related to other factors such as appetite changes or metabolic issues.

4. A client who received Prochlorperazine 4 hours ago reports spasms of his face. The nurse should anticipate a prescription for which of the following medications?

• A. Fomepizole
• B. Naloxone
• C. Phytonadione
• D. Diphenhydramine

Correct answer: D

Rationale: An adverse effect of prochlorperazine is acute dystonia, which is evidenced by spasms of the muscles in the face, neck, and tongue. Diphenhydramine is used to suppress extrapyramidal effects of prochlorperazine, making it the most appropriate choice to address the client's spasms. Fomepizole is used in methanol or ethylene glycol poisoning, not for acute dystonia. Naloxone is an opioid antagonist used for opioid overdose, not for acute dystonia. Phytonadione is vitamin K, used for the reversal of warfarin, not for acute dystonia.

5. A client presents in the Emergency Department with a suspected MI. Which medication should NOT be given as soon as possible?

• A. Clopidogrel (Plavix)
• B. Morphine
• C. Aspirin (ASA)
• D. Metoprolol (Lopressor)

Correct answer: A

Rationale: In the setting of a suspected myocardial infarction (MI), the priority medications to administer as soon as possible include aspirin (ASA) and possibly morphine to manage pain and anxiety. Clopidogrel (Plavix) is not typically administered immediately in the emergency setting for MI management. Metoprolol (Lopressor) is indicated after aspirin administration and stabilization of the patient. Therefore, in this scenario, clopidogrel should NOT be given as a first-line medication for a suspected MI.
