Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

3. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2°F and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?

• A. Occult blood in the stool
• B. Abdominal distention
• C. Elevated urine specific gravity
• D. Hyperactive bowel sounds

Correct answer: C

Rationale: Elevated urine specific gravity is a sign of dehydration in children. In the scenario provided, the child is experiencing increased stool frequency, liquid consistency, fever, and vomiting, indicating fluid loss and potential dehydration. Occult blood in the stool may suggest gastrointestinal bleeding but is not a direct indicator of dehydration. Abdominal distention can be seen in various conditions and is not specific to dehydration. Hyperactive bowel sounds are more commonly associated with increased bowel motility, not necessarily dehydration.

4. The nurse enters the room of a client with a nasogastric tube who is receiving continuous feeding. The nurse observes that the client is coughing and that the infusion pump is alarming. What action should the nurse take first?

• A. Auscultate the client's breath sounds
• B. Turn the client to the side
• C. Stop the feeding infusion
• D. Notify the healthcare provider

Correct answer: C

Rationale: The correct action for the nurse to take first in this situation is to stop the feeding infusion. Coughing in a client with a nasogastric tube can indicate aspiration, which can be a serious complication. By stopping the feeding infusion immediately, the nurse can prevent further aspiration and related complications. Auscultating breath sounds or turning the client to the side may be necessary actions but addressing the feeding infusion is the priority. Notifying the healthcare provider can be done after the immediate issue of potential aspiration is managed.

5. The nurse is caring for a client who is 2 days post-op following an abdominal surgery. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?

• A. Apply a sterile saline dressing to the wound
• B. Notify the healthcare provider
• C. Administer pain medication
• D. Cover the wound with an abdominal binder

Correct answer: A

Rationale: In this situation, the priority action for the nurse is to apply a sterile saline dressing to the wound. This helps prevent infection and keeps the wound moist, which is crucial in promoting healing and preventing further complications. Option B, notifying the healthcare provider, is important but should come after addressing the wound. Administering pain medication (Option C) may be necessary but is not the first action to take in this emergency situation. Covering the wound with an abdominal binder (Option D) is not appropriate and may cause further harm by applying pressure to the protruding bowel.
