1. A child is brought to the emergency department after ingesting an unknown quantity of acetaminophen. What is the most important action for the nurse to take?

• A. Assess the child's level of consciousness.
• B. Prepare to administer activated charcoal.
• C. Notify the poison control center.
• D. Obtain an order for serum acetaminophen levels.

Correct Answer: D

Rationale: Obtaining serum acetaminophen levels is critical in determining the level of toxicity and guiding treatment. It helps to assess the risk of hepatotoxicity and determine the need for antidotal therapy with N-acetylcysteine. Assessing the child's level of consciousness (Choice A) is important but obtaining serum acetaminophen levels takes precedence as it directly guides the specific treatment required. Activated charcoal (Choice B) is not routinely used in acetaminophen poisoning. While notifying the poison control center (Choice C) is important, obtaining serum acetaminophen levels should be the immediate action to assess the child's condition and guide treatment.

2. A client with a venous leg ulcer is receiving compression therapy. What assessment finding requires immediate intervention?

• A. Decreased pain and increased redness around the ulcer.
• B. Increased serous drainage from the ulcer site.
• C. Cool extremities and weak peripheral pulses.
• D. Pitting edema around the ulcer site.

Correct Answer: C

Rationale: The correct answer is C. Cool extremities and weak peripheral pulses indicate compromised circulation, possibly due to inadequate arterial blood supply. This finding requires immediate intervention to prevent further complications such as tissue damage or non-healing ulcers. Option A, decreased pain and increased redness, can be a sign of improving wound condition. Option B, increased serous drainage, may indicate a normal part of the healing process. Option D, pitting edema, is common in venous leg ulcers and may not require immediate intervention unless severe and accompanied by other concerning symptoms.

3. 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.

4. A client has burns covering 40% of their total body surface area (TBSA). What is the nurse’s priority action?

• A. Monitor the client's urinary output hourly.
• B. Apply cool, moist dressings to the burned areas.
• C. Administer pain medication to reduce discomfort.
• D. Administer IV fluids to prevent hypovolemia.

Correct Answer: A

Rationale: The correct answer is A: Monitor the client's urinary output hourly. Clients with burns covering a large percentage of their total body surface area are at high risk for hypovolemia due to fluid loss. Monitoring urinary output is crucial because it helps assess kidney function and fluid balance, providing essential information about the client's hemodynamic status. Applying cool, moist dressings (choice B) is important but not the priority over assessing fluid balance. Administering pain medication (choice C) is essential for comfort but not the priority over monitoring for potential complications like hypovolemia. Administering IV fluids (choice D) is important to prevent hypovolemia, but monitoring urinary output should be the priority to guide fluid resuscitation.

5. A client receiving chemotherapy for cancer treatment is experiencing nausea and vomiting. What is the nurse's best intervention to manage these symptoms?

• A. Offer frequent, small meals
• B. Administer antiemetics before meals
• C. Encourage the client to eat a high-fat diet
• D. Provide the client with cold, carbonated beverages

Correct Answer: B

Rationale: Administering antiemetics before meals is the best intervention to manage nausea and vomiting in clients receiving chemotherapy. This proactive approach helps control symptoms by preventing nausea from occurring, rather than waiting to treat it once symptoms have already started. Offering frequent, small meals (choice A) may worsen symptoms in some cases due to increased stomach activity. Encouraging a high-fat diet (choice C) can be difficult for nauseated clients and may not alleviate symptoms. Providing cold, carbonated beverages (choice D) could exacerbate nausea further due to the temperature and carbonation.
