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

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 should a healthcare professional assess in a patient presenting with symptoms of a stroke?

Correct answer: A

Rationale: When assessing a patient with suspected stroke symptoms, it is crucial to check for facial drooping as it can be a sign of facial nerve weakness, which is a common indicator of stroke. While monitoring speech difficulties and evaluating arm weakness are also important assessments in stroke cases, they are secondary to facial drooping. Checking for the time of onset of symptoms is essential to determine eligibility for time-sensitive treatments like thrombolytic therapy, but when prioritizing assessments, facial drooping takes precedence.

3. What is the most important step when preparing to administer a blood transfusion?

Correct answer: B

Rationale: The correct answer is B: Ensure the blood type is compatible with the client. This is the most crucial step in preparing for a blood transfusion to prevent severe transfusion reactions. Checking the client for a fever (Choice A) is important but not the most critical step. Administering blood via IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow drip. Warming the blood to body temperature (Choice D) is not a standard practice and can lead to hemolysis, making it an incorrect choice.

4. Which nursing intervention is best for a client with constipation?

Correct answer: C

Rationale: Increasing fiber intake is the most appropriate nursing intervention for a client experiencing constipation. Fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Encouraging the client to remain in bed may exacerbate constipation by reducing movement and promoting inactivity. While stool softeners can be beneficial, they are typically used as a short-term solution and may not address the underlying issue of low fiber intake. Regular exercise is important for overall bowel health; however, in the immediate management of constipation, increasing fiber intake is the most effective intervention.

5. A nurse is assisting with an in-service about hepatitis A for a group of staff nurses. The nurse should include that hepatitis A is transmitted through which of the following methods?

Correct answer: D

Rationale: The correct answer is D: Consumption of contaminated food. Hepatitis A is primarily transmitted through the ingestion of contaminated food or water. Airborne droplets and sexual contact are not common modes of transmission for hepatitis A. While contact with contaminated surfaces can play a role in the spread of some infections, hepatitis A is not typically transmitted through this route.
