Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. Prior to surgery, written consent must be obtained. What is the nurse's legal responsibility with regard to obtaining written consent?

• A. Witness the consent and sign the form as a witness
• B. Inform the client of alternatives to the procedure
• C. Explain the procedure in detail to the client
• D. Determine that the surgical consent form has been signed and is included in the client's record

Correct answer: D

Rationale: The nurse's legal responsibility is to ensure that informed consent has been obtained by verifying that the client has signed the form and that it is included in the record. Witnessing the consent and signing as a witness is not the nurse's role, as this is typically done by a neutral party. Informing the client of alternatives to the procedure and explaining the procedure in detail are responsibilities of the healthcare provider performing the surgery, not the nurse.

3. A client with a recent myocardial infarction is prescribed a beta-blocker. What side effect should the nurse monitor for?

• A. Monitor the client for bradycardia.
• B. Check the client’s blood pressure for signs of hypotension.
• C. Monitor the client for signs of hyperglycemia.
• D. Monitor for signs of fluid retention.

Correct answer: B

Rationale: The correct answer is B: 'Check the client’s blood pressure for signs of hypotension.' Beta-blockers can lead to decreased heart rate, but bradycardia is not the primary side effect to monitor. Monitoring for bradycardia is more relevant when administering medications like digoxin. Hyperglycemia is associated with medications like corticosteroids, not beta-blockers. Fluid retention is a side effect seen with medications like corticosteroids or calcium channel blockers, not beta-blockers. Therefore, in a client taking a beta-blocker after a myocardial infarction, monitoring for hypotension is crucial due to the medication's mechanism of action.

4. A client with atrial fibrillation is prescribed warfarin. Which instruction should the nurse include in the teaching?

• A. Maintain a consistent intake of leafy green vegetables
• B. Use an electric razor when shaving
• C. Monitor blood pressure daily
• D. Avoid eating bananas and oranges

Correct answer: B

Rationale: Clients on warfarin are at increased risk of bleeding due to its anticoagulant effects. Using an electric razor reduces the risk of cuts and bleeding, which is an important safety precaution. While leafy greens should not be avoided, their intake should be consistent to maintain a stable level of vitamin K in the body. Monitoring blood pressure daily is important for other conditions but not directly related to warfarin therapy. Avoiding bananas and oranges is not a standard instruction for clients on warfarin.

5. A client with deep vein thrombosis (DVT) is receiving heparin and reports tarry stools. What should the nurse do?

• A. Prepare to administer warfarin.
• B. Assess characteristics of the client's pain.
• C. Monitor stools for blood and review PTT results.
• D. Continue the heparin and prepare to administer Vitamin K.

Correct answer: C

Rationale: When a client on heparin reports tarry stools, it can be indicative of gastrointestinal bleeding. The correct action for the nurse is to monitor the stools for blood and review the Partial Thromboplastin Time (PTT) results. This is essential to detect any potential bleeding complications associated with heparin therapy. Option A is incorrect because warfarin is not the immediate intervention for tarry stools in a client on heparin. Option B is irrelevant to the situation described. Option D is incorrect as Vitamin K is the antidote for warfarin, not heparin.
