Nursing Elites

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

• A. Increase your intake of leafy green vegetables.
• B. Avoid foods high in vitamin K.
• C. Increase your intake of dairy products.
• D. Avoid foods high in iron.

Correct answer: B

Rationale: The correct answer is to avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of Warfarin by counteracting its anticoagulant effects. Foods high in vitamin K, such as leafy green vegetables, should be limited in the diet of individuals taking Warfarin to maintain a consistent level of the medication's effectiveness. Choices A, C, and D are incorrect as increasing intake of leafy green vegetables (choice A) and dairy products (choice C) may increase the intake of vitamin K, which is not recommended, and avoiding foods high in iron (choice D) is not directly related to Warfarin therapy.

2. A client is prescribed Digoxin. Which of the following findings should the nurse monitor as a sign of potential toxicity?

• A. Bradycardia
• B. Hypertension
• C. Hyperglycemia
• D. Hypocalcemia

Correct answer: A

Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin can lead to toxicity, which can manifest as various signs and symptoms, including bradycardia. Monitoring the client's heart rate closely is crucial to detect and manage potential toxicity early. Hypertension, hyperglycemia, and hypocalcemia are not typically associated with Digoxin toxicity; therefore, they are incorrect choices.

3. A healthcare provider is educating a client who has a prescription for Theophylline. Which of the following instructions should the healthcare provider include?

• A. Avoid caffeine while taking this medication.
• B. You should increase your fluid intake.
• C. Take this medication in the evening.
• D. You may experience increased appetite while on this medication.

Correct answer: A

Rationale: The correct answer is A: 'Avoid caffeine while taking this medication.' Caffeine can increase the risk of theophylline toxicity as it competes for the same metabolic pathways. Consuming caffeine while on theophylline can lead to adverse effects. Choice B is incorrect because although maintaining adequate hydration is important, it is not a specific instruction related to theophylline use. Choice C is incorrect as the timing of the medication administration should be based on the healthcare provider's recommendation and the client's individual needs. Choice D is incorrect as increased appetite is not a common side effect associated with theophylline.

4. To which pharmacologic classification does the drug propranolol belong?

• A. Beta Blockers
• B. Cholinergics
• C. Immune globulins
• D. Barbiturates

Correct answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.

5. A client has a new prescription for Lithium Carbonate. When teaching the client about ways to prevent Lithium toxicity, what advice should the nurse provide?

• A. Avoid using acetaminophen for headaches.
• B. Restrict intake of foods high in sodium.
• C. Decrease fluid intake to less than 1,500 mL daily.
• D. Limit aerobic activity in hot weather.

Correct answer: D

Rationale: The nurse should advise the client to limit aerobic activity in hot weather to prevent sodium/water depletion, which can increase the risk for Lithium toxicity. Excessive sweating and fluid loss can lead to dehydration and changes in lithium levels, potentially resulting in toxicity. Choices A, B, and C are incorrect. Avoiding acetaminophen for headaches is not directly related to Lithium toxicity. Restricting sodium intake and decreasing fluid intake can lead to increased lithium levels and toxicity, so these are not recommended actions.
