Nursing Elites

1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

2. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

• A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
• B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• C. An infusion of medication in the spinal canal will block pain perception
• D. The discharge of electricity will distract the client's focus on the pain

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

3. A client is admitted to the hospital with second and third degree burns to the face and neck. How should the nurse best position the client to maximize function of the neck and face and prevent contracture?

• A. The neck extended backward using a rolled towel behind the neck
• B. Prone position using pillows to support both arms outward from the torso
• C. Side-lying position using pillows to support the abdomen and back
• D. The neck forward using pillows under the head and sandbags on both sides

Correct answer: D

Rationale: After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing. Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck. Choice A could potentially exacerbate neck contractures, Choice B focuses on arm support rather than neck and face positioning, and Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.

4. During a manic episode, what is the most appropriate intervention to implement first for a client with bipolar disorder?

• A. Engage the client in a quiet activity
• B. Provide a structured environment with minimal stimulation
• C. Monitor the client continuously
• D. Adjust the lighting and noise levels

Correct answer: B

Rationale: During a manic episode, individuals with bipolar disorder may experience sensory overload and agitation. Providing a structured environment with minimal stimulation is the most appropriate initial intervention as it can help reduce overwhelming sensory input and promote a sense of calm. Engaging the client in a quiet activity (Choice A) may not be effective if the environment is still overstimulating. Continuous monitoring (Choice C) is important but may not be the first intervention needed. Adjusting lighting and noise levels (Choice D) can be helpful but may not address the core issue of sensory overload and agitation during a manic episode.

5. A healthcare provider is reviewing a client's medication list during a routine visit. Which action is most important to ensure medication safety?

• A. Ask the client about any allergies to medications
• B. Review the purposes of each medication
• C. Check for potential drug interactions
• D. All of the above

Correct answer: D

Rationale: A comprehensive review of allergies, medication purposes, and potential interactions is crucial for ensuring medication safety. Asking about allergies helps prevent adverse reactions, reviewing medication purposes ensures the correct use of each drug, and checking for potential drug interactions reduces the risk of harmful effects when medications interact. Choosing 'All of the above' is the correct answer because all three actions are essential steps to enhance medication safety. Options A, B, and C individually play vital roles in promoting medication safety, making option D the most appropriate choice.
