Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A client has a nasogastric tube and is receiving intermittent enteral feedings. Which of the following actions should the nurse take to prevent aspiration?

• A. Administer a bolus feeding over 10 minutes.
• B. Elevate the head of the bed to 45 degrees during feedings.
• C. Flush the tube with 10 mL of sterile water before feedings.
• D. Position the client on the left side during feedings.

Correct answer: B

Rationale: To prevent aspiration in clients with a nasogastric tube receiving intermittent enteral feedings, the nurse should elevate the head of the bed to 45 degrees during feedings. This position helps reduce the risk of regurgitation and aspiration of the feeding contents. Administering a bolus feeding over 10 minutes (choice A) may not prevent aspiration as effectively as elevating the head of the bed. Flushing the tube with sterile water before feedings (choice C) is important for tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (choice D) is not the recommended action to prevent aspiration; elevating the head of the bed is more effective.

3. A nurse is caring for a client who has pneumonia. Which of the following findings should the nurse identify as an indication of the effectiveness of the treatment?

• A. Respiratory rate of 24/min
• B. White blood cell count of 15,000/mm3
• C. SpO2 of 95%
• D. Clear breath sounds

Correct answer: D

Rationale: Clear breath sounds are an essential indicator of effective pneumonia treatment as they suggest resolution of the lung infection. A normal respiratory rate (A) indicates adequate breathing but does not directly reflect the effectiveness of pneumonia treatment. An elevated white blood cell count (B) is a sign of infection and may not decrease immediately with treatment. While maintaining an SpO2 of 95% (C) is crucial for oxygenation, it may not directly indicate the effectiveness of pneumonia treatment.

4. A nurse is caring for a client who has acute pancreatitis. Which of the following laboratory results should the nurse expect to be elevated?

• A. Serum creatinine.
• B. Amylase.
• C. Hemoglobin.
• D. Blood glucose.

Correct answer: B

Rationale: The correct answer is B: Amylase. Amylase is typically elevated in clients with acute pancreatitis due to inflammation of the pancreas. Elevated serum creatinine levels are more indicative of kidney dysfunction rather than pancreatitis. Hemoglobin levels are not directly related to pancreatitis. While blood glucose levels can be affected by pancreatitis, they are not typically the primary laboratory result expected to be elevated in this condition.

5. A nurse is providing teaching to a client who has a new prescription for ferrous sulfate. Which of the following instructions should the nurse include?

• A. Take this medication with orange juice to increase absorption.
• B. Take this medication on an empty stomach.
• C. Take this medication with milk if it causes stomach upset.
• D. Take this medication at bedtime.

Correct answer: A

Rationale: The correct instruction for a client prescribed ferrous sulfate is to take the medication with orange juice to enhance absorption. Orange juice is recommended because of its vitamin C content, which aids in the absorption of iron. Choice B, taking the medication on an empty stomach, is incorrect because ferrous sulfate is better absorbed with food. Choice C, taking the medication with milk if it causes stomach upset, is incorrect as calcium in milk can interfere with iron absorption. Choice D, taking the medication at bedtime, is incorrect as it is usually recommended to take iron supplements between meals or with food to enhance absorption.
