Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. What are the risk factors for pressure ulcer development?

• A. Immobility and poor nutrition
• B. Obesity and diabetes
• C. Dehydration and malnutrition
• D. Use of assistive devices and prolonged bedrest

Correct answer: A

Rationale: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.

3. A nurse in a long-term care facility is contributing to the plan of care for a client who has a new ostomy. Which of the following interventions should the nurse include?

• A. Change the appliance daily
• B. Clean the stoma once a day
• C. Avoid changing the appliance for a week
• D. Change the appliance twice each week

Correct answer: D

Rationale: The correct answer is to change the appliance twice each week. Changing the appliance too frequently can irritate the skin around the stoma, while not changing it often enough can lead to infection. Changing the appliance twice a week helps to maintain hygiene without causing irritation. Choices A, B, and C are incorrect because changing the appliance daily can cause irritation, cleaning the stoma once a day may not be sufficient for proper hygiene, and avoiding changing the appliance for a week can increase the risk of infection and skin breakdown.

4. A nurse is collecting data from a client who has a newly applied cast to the right lower extremity. Which of the following findings should the nurse expect?

• A. Capillary refill of 1 second
• B. Capillary refill of 5 seconds
• C. Pitting edema
• D. Shortness of breath

Correct answer: B

Rationale: When assessing a client with a newly applied cast, the nurse should expect a capillary refill of approximately 2 seconds, as this indicates adequate circulation. A capillary refill longer than 3 seconds suggests impaired circulation, which is abnormal. Therefore, a capillary refill of 5 seconds is the finding the nurse should expect. Pitting edema and shortness of breath are not typically directly related to a newly applied cast and should not be expected findings in this scenario.

5. A nurse is planning care for a school-age child who is 4 hr postoperative following perforated appendicitis. Which of the following actions should the nurse include in the plan of care?

• A. Offer small amounts of clear liquids 6 hr following surgery.
• B. Give cromolyn nebulizer solution every 6 hr.
• C. Apply a warm compress to the operative site every 4 hr.
• D. Administer analgesics on a scheduled basis for the first 24 hr.

Correct answer: D

Rationale: Administering analgesics on a scheduled basis for the first 24 hours is crucial to ensure adequate pain control in the immediate postoperative period. Choice A is incorrect because clear liquids are typically initiated gradually and advanced as tolerated but not specifically at 6 hours post-surgery. Choice B is incorrect as cromolyn nebulizer solution is not indicated for postoperative pain management in this scenario. Choice C is incorrect as applying a warm compress may not be appropriate for the operative site after appendicitis surgery and can potentially increase the risk of infection.
