Nursing Elites

1. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of citrus fruits.
• D. Avoid high-sodium foods.

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

2. A client with chronic pain is prescribed a fentanyl (Duragesic) patch. Which instruction should the nurse provide to the client?

• A. Apply the patch to a clean, dry, and hairless area of the skin.
• B. Use a heating pad over the patch to enhance absorption.
• C. Change the patch daily to maintain effectiveness.
• D. Place the patch on the same site with each application.

Correct answer: A

Rationale: The correct instruction for applying a fentanyl (Duragesic) patch is to place it on a clean, dry, and hairless area of the skin. This ensures proper adhesion of the patch and optimal absorption of the medication. Using a heating pad over the patch is contraindicated as it can increase drug absorption and lead to overdose. Changing the patch daily is necessary for some medications, but fentanyl patches are usually changed every 72 hours to maintain a steady blood level of the medication. Placing the patch on the same site with each application can lead to skin irritation, uneven drug absorption, and should be avoided to allow the skin to recover between applications.

3. A client with a newly created ileostomy has not had ostomy output for the past 12 hours and reports worsening nausea. What is the nurse's priority action?

• A. Facilitate a referral to the wound-ostomy-continence (WOC) nurse
• B. Report signs and symptoms of obstruction to the health care provider
• C. Encourage the client to mobilize to enhance mobility
• D. Contact the health care provider to obtain a swab of the stoma for culture

Correct answer: B

Rationale: The nurse's priority action in this situation is to report signs and symptoms of possible obstruction to the healthcare provider. Lack of ostomy output and worsening nausea can indicate a potential obstruction, which requires immediate attention and intervention to prevent complications.

4. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

5. What is an important teaching point for a patient prescribed dabigatran for atrial fibrillation?

• A. Take the medication with food to enhance absorption.
• B. Do not crush or chew the capsules.
• C. Increase intake of green leafy vegetables.
• D. Avoid all dairy products.

Correct answer: B

Rationale: The correct teaching point for a patient prescribed dabigatran is not to crush or chew the capsules. Doing so can alter the absorption of the medication, increasing the risk of bleeding. It is important for patients to swallow the capsules whole to ensure proper delivery of the medication.
