Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw catheter in a circular motion

Correct answer: A

Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.

3. A client with Type 1 diabetes reports feeling shaky and lightheaded. The nurse checks the client's blood glucose level and it is 60 mg/dL. What action should the nurse take first?

• A. Give the client a glucagon injection
• B. Encourage the client to eat a high-protein snack
• C. Recheck the blood glucose level in 15 minutes
• D. Administer 15 grams of a fast-acting carbohydrate

Correct answer: D

Rationale: The correct answer is D: Administer 15 grams of a fast-acting carbohydrate. The first step in treating hypoglycemia is to quickly raise the client's blood sugar level. Fast-acting carbohydrates like glucose tablets or juice are essential for this purpose. Giving a glucagon injection is typically reserved for severe hypoglycemia when the client is unable to take anything by mouth. Encouraging the client to eat a high-protein snack is not appropriate for immediate treatment of hypoglycemia. Rechecking the blood glucose level in 15 minutes is important after administering the fast-acting carbohydrate to ensure that the blood sugar has returned to a safe level.

4. To auscultate for a carotid bruit, where should the nurse place the stethoscope?

• A. Base of the neck on the right side
• B. Above the clavicle
• C. Over the sternum
• D. Over the trachea

Correct answer: A

Rationale: To auscultate for a carotid bruit, the nurse should place the stethoscope at the base of the neck, near the carotid artery. A carotid bruit is an abnormal sound that indicates turbulent blood flow in the carotid artery, potentially due to arterial narrowing or atherosclerosis. Placing the stethoscope above the clavicle, over the sternum, or over the trachea would not provide the nurse with the optimal location to assess for carotid artery abnormalities.

5. A client with deep vein thrombosis (DVT) is prescribed warfarin. What teaching should the nurse provide?

• A. Avoid foods high in vitamin K, such as spinach.
• B. Report any signs of bleeding, such as bruising or nosebleeds.
• C. Take the medication on an empty stomach.
• D. Monitor for changes in blood pressure.

Correct answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.
