Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. A patient with diabetes should be advised to avoid which type of carbohydrate?

• A. Simple carbohydrates
• B. Complex carbohydrates
• C. Fiber-rich carbohydrates
• D. All carbohydrates

Correct answer: A

Rationale: The correct answer is A: Simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels, which can be problematic for patients with diabetes. These carbohydrates are quickly broken down and absorbed by the body, leading to sharp increases in blood sugar levels. In contrast, complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes because they are digested more slowly, resulting in a more gradual rise in blood glucose levels. Choice B, complex carbohydrates, are a better option for diabetic patients compared to simple carbohydrates. Choice C, fiber-rich carbohydrates, can also be beneficial for individuals with diabetes as they help in regulating blood sugar levels. Choice D, all carbohydrates, is too broad of a statement as not all carbohydrates have the same impact on blood glucose levels.

3. The nurse supervises care of a client who is receiving enteral feeding via a nasogastric tube. The nurse determines that care is appropriate if which of the following is observed? (Select all that apply)

• A. The nursing assistant aspirates and measures the amount of the gastric aspirate
• B. The nursing assistant elevates the head of the client’s bed 30 degrees
• C. The nursing assistant warms the formula to room temperature
• D. B, C

Correct answer: D

Rationale: Elevating the head of the bed to 30 degrees reduces the risk of aspiration by promoting proper digestion and preventing reflux. Warming the formula to room temperature is essential to prevent discomfort and complications. Aspirating and measuring the gastric aspirate is not a recommended nursing action for monitoring enteral feeding via a nasogastric tube, as it can introduce the risk of introducing contaminants into the feeding tube. Therefore, choices A and B are incorrect, making choice D the correct answer.

4. A client scheduled for surgery cannot sign the operative consent form because he has been sedated with opioid analgesics. The nurse should take which best action regarding the informed consent?

• A. Obtain a court order for the surgery
• B. Sign the informed consent on behalf of the client
• C. Send the client to surgery without the consent form being signed
• D. Obtain a telephone consent from a family member, with the consent being witnessed by two healthcare providers

Correct answer: D

Rationale: In situations where a client is unable to sign the consent form, obtaining a telephone consent from a family member, with the consent being witnessed by two healthcare providers, is the best course of action. This ensures that the client's best interests are considered and that proper authorization is obtained. Option A, obtaining a court order, is not necessary in this scenario and could delay the surgery. Option B, signing the consent on behalf of the client, is not appropriate as it may raise ethical and legal concerns. Option C, sending the client to surgery without a signed consent form, is not advisable as it violates the principles of informed consent and places the client at risk.

5. Which nursing instruction should the nurse discuss with the client who is receiving glucocorticoids for Addison’s disease?

• A. Discuss the importance of tapering medications when discontinuing medication
• B. Explain that the dose will need to be decreased during times of stress or infection
• C. Instruct the client to take medication on an empty stomach with a glass of water
• D. Encourage the client to wear a MedicAlert bracelet and carry a card in the wallet

Correct answer: A

Rationale: The correct answer is A because tapering glucocorticoids is crucial to prevent adrenal insufficiency, which can occur if the medication is stopped abruptly. Choice B is incorrect as it refers to dose adjustments during stress or infection, not discontinuation. Choice C is incorrect because it does not specifically address the issue of stopping the medication. Choice D is not directly related to the management of glucocorticoid therapy for Addison’s disease.
