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 has a nasogastric tube for gastric decompression. Which of the following actions should the nurse take?

• A. Check for the presence of bowel sounds every 8 hours.
• B. Flush the NG tube every 24 hours.
• C. Provide the client with sips of water every 2 hours.
• D. Keep the client's head of the bed elevated to 45 degrees.

Correct answer: D

Rationale: The correct answer is to keep the client's head of the bed elevated to 45 degrees. This position helps prevent aspiration in clients with a nasogastric tube for gastric decompression by reducing the risk of reflux and promoting proper drainage. Choice A is incorrect because checking for bowel sounds is not directly related to the care of a nasogastric tube. Choice B is incorrect as flushing the NG tube every 24 hours is not a standard nursing practice and may lead to complications. Choice C is incorrect because providing sips of water may interfere with the purpose of gastric decompression, which is to keep the stomach empty.

3. 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.

4. A client who is 2 hours postoperative following a kidney biopsy is being assessed by a nurse. Which of the following findings should the nurse report to the provider?

• A. Urinary output of 30 mL/hr.
• B. Hemoglobin 10 g/dL.
• C. Respiratory rate of 16/min.
• D. Blood pressure 110/70 mm Hg.

Correct answer: B

Rationale: The correct answer is B. A hemoglobin level of 10 g/dL is below the normal range and should be reported following a kidney biopsy to check for bleeding. Decreased hemoglobin levels could indicate internal bleeding, which is a significant concern postoperatively. Choices A, C, and D are within normal limits and do not require immediate reporting. Urinary output of 30 mL/hr is also within the acceptable range for a postoperative client. A respiratory rate of 16/min and blood pressure of 110/70 mm Hg are both normal findings postoperatively.

5. A nurse is providing teaching about folic acid to a client who is primigravida. Which of the following information should the nurse include in the teaching?

• A. You should take folic acid to prevent neural tube defects in your baby.
• B. You should consume at least 400 micrograms of folic acid daily.
• C. You can increase your dietary intake of folic acid by consuming cereals and citrus fruits.
• D. You should expect improved energy levels when taking folic acid supplements.

Correct answer: C

Rationale: The correct answer is C. Folic acid helps prevent neural tube defects, and dietary sources like cereals and citrus fruits are good options to increase folic acid intake. Choice A is incorrect because folic acid is primarily recommended to prevent neural tube defects, not to prevent infections. Choice B is incorrect because the recommended daily intake of folic acid for pregnant women is at least 400 micrograms, not 300. Choice D is incorrect because folic acid is not typically associated with improving energy levels.
