Nursing Elites

1. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

2. A client with type 1 diabetes mellitus is being taught self-administration of insulin by a nurse. Which of the following instructions should the nurse include?

• A. Inject air into the vial before withdrawing the insulin.
• B. Draw up the short-acting insulin first, then the long-acting insulin.
• C. Store unopened insulin vials in the freezer.
• D. Rotate injection sites within the same anatomical region.

Correct answer: D

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same anatomical region. This practice helps reduce the risk of lipodystrophy, a condition characterized by fatty tissue changes due to repeated insulin injections in the same spot. By rotating sites, the client ensures better insulin absorption and prevents localized skin changes. Injecting air into the vial before withdrawing insulin (Choice A) is unnecessary and not recommended. Drawing up short-acting insulin before long-acting insulin (Choice B) is not a standard practice and can lead to errors in dosing. Storing unopened insulin vials in the freezer (Choice C) is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness.

3. A client is being assessed in the PACU. Which of the following findings indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: Oliguria is a sign of decreased cardiac output. Decreased cardiac output can lead to poor renal perfusion, resulting in decreased urine output (oliguria). This requires immediate intervention to improve cardiac function and perfusion. Shivering (Choice A) is a response to cold stress and does not directly indicate decreased cardiac output. Bradypnea (Choice C) refers to abnormally slow breathing rate and is more indicative of respiratory issues rather than decreased cardiac output. Constricted pupils (Choice D) are associated with the parasympathetic nervous system response and not directly related to cardiac output.

4. A client with osteoporosis needs to increase calcium intake. Which of the following foods should be recommended by the nurse?

• A. Carrots
• B. Broccoli
• C. Chicken
• D. Bananas

Correct answer: B

Rationale: The correct answer is B: Broccoli. Broccoli is rich in calcium and is a suitable food to recommend to clients with osteoporosis to increase their calcium intake. Carrots, chicken, and bananas are not as high in calcium content compared to broccoli and therefore not the most appropriate choices for increasing calcium intake in clients with osteoporosis.

5. A client receiving a blood transfusion develops a fever. What action should the nurse take?

• A. Stop the transfusion immediately.
• B. Administer an antihistamine as prescribed.
• C. Administer a diuretic as prescribed.
• D. Increase the transfusion rate.

Correct answer: A

Rationale: When a client receiving a blood transfusion develops a fever, the priority action for the nurse is to stop the transfusion immediately. A fever during a blood transfusion may indicate a transfusion reaction, and stopping the transfusion is crucial to prevent further complications. Administering an antihistamine (choice B) or a diuretic (choice C) without assessing and addressing the potential transfusion reaction can be harmful. Increasing the transfusion rate (choice D) is contraindicated as it can exacerbate any adverse reactions the client is experiencing.
