Nursing Elites

1. The healthcare provider is reinforcing teaching for a client who is starting statin therapy. Which dietary advice should the healthcare provider give?

• A. Eat more whole grains.
• B. Avoid foods high in potassium.
• C. Avoid grapefruit and grapefruit juice.
• D. Increase intake of dairy products.

Correct answer: C

Rationale: The correct answer is C: Avoid grapefruit and grapefruit juice. Grapefruit and grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. It is crucial for clients on statin therapy to avoid grapefruit products to ensure the medication's effectiveness and safety. Choices A, B, and D are incorrect because they do not directly impact the metabolism or effectiveness of statin therapy.

2. A client with a history of coronary artery disease (CAD) is prescribed simvastatin (Zocor). The nurse should teach the client about which potential side effect?

• A. Muscle pain
• B. Dry mouth
• C. Drowsiness
• D. Diarrhea

Correct answer: A

Rationale: Muscle pain is a common side effect of statins like simvastatin and can indicate a serious condition called rhabdomyolysis. Rhabdomyolysis is a severe condition where muscle fibers break down rapidly, releasing myoglobin into the bloodstream, which can lead to kidney damage. Therefore, it's important for the nurse to educate the client about this potential side effect and to promptly report any muscle pain to the healthcare provider. Dry mouth, drowsiness, and diarrhea are not commonly associated with simvastatin use and are less concerning compared to the risk of rhabdomyolysis.

3. Prior to a dipyridamole thallium scan, what substance should the LPN/LVN ensure the client has not consumed?

• A. Caffeine
• B. Fatty meal
• C. Excess sugar
• D. Milk products

Correct answer: A

Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Fatty meals, excess sugar, and milk products do not specifically interfere with the dipyridamole thallium scan procedure. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.

4. The client is being taught about the use of sublingual nitroglycerin for chest pain. Which instruction should be provided?

• A. Swallow the tablet whole with water.
• B. Place the tablet under the tongue and let it dissolve.
• C. Chew the tablet and then swallow.
• D. Place the tablet between the cheek and gum.

Correct answer: B

Rationale: The correct method for administering sublingual nitroglycerin is to place the tablet under the tongue and allow it to dissolve. This route of administration facilitates rapid absorption of the medication into the bloodstream, enabling quick relief of chest pain associated with angina or heart conditions. Choice A is incorrect because sublingual nitroglycerin should not be swallowed whole. Choice C is wrong as chewing the tablet can lead to the rapid release of the drug, causing adverse effects like headaches or dizziness. Choice D is also incorrect as the tablet should not be placed between the cheek and gum, but under the tongue for proper absorption.

5. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin). The nurse should include which instruction in the discharge teaching?

• A. Take the medication at the same time each day
• B. Avoid green leafy vegetables in your diet
• C. Increase your intake of vitamin K-rich foods
• D. Stop the medication if you notice any bruising

Correct answer: A

Rationale: Taking warfarin at the same time each day is crucial to maintain consistent blood levels and ensure the effectiveness of the medication in preventing clot formation. Consistent timing helps in monitoring and adjusting the dosage as needed to keep the international normalized ratio (INR) within the therapeutic range to prevent clotting events or excessive bleeding. Choices B, C, and D are incorrect. Avoiding green leafy vegetables is a misconception; while they are high in vitamin K which antagonizes warfarin, they should not be avoided but consumed in moderation. Increasing vitamin K-rich foods can interfere with warfarin's effectiveness. Stopping the medication due to bruising can be dangerous as it may indicate a clotting problem that the medication is intended to prevent.
