Nursing Elites

1. 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.

2. When reconstituted, how many milligrams are in each milliliter of solution?

• A. 300 mg/mL
• B. 350 mg/mL
• C. 450 mg/mL
• D. 400 mg/mL

Correct answer: D

Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.

3. Before administration of a stat dose of potassium chloride IV for a client with hypokalemia, what is the most important action for the nurse?

• A. Ensure the IV is flowing freely
• B. Mix the medication thoroughly
• C. Check the client’s electrolyte levels
• D. Obtain a baseline ECG

Correct answer: A

Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.

4. The nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?

• A. Restrict sodium intake
• B. Encourage high-protein meals
• C. Increase fluid intake
• D. Administer diuretics as prescribed

Correct answer: D

Rationale: The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.

5. Which client will benefit most from the application of pneumatic compression devices to the lower extremities? The client who

• A. is immobile on prescribed bedrest.
• B. has pressure ulcers on several toes.
• C. has diminished pedal pulse volume.
• D. is confused and trying to climb out of bed.

Correct answer: A

Rationale: The correct answer is A. Pneumatic compression devices are most beneficial for immobile clients on prescribed bedrest to prevent deep vein thrombosis. Applying these devices helps in promoting circulation and preventing blood clots. Choices B, C, and D do not specifically relate to the primary indication for pneumatic compression devices, making them incorrect. Pressure ulcers, diminished pedal pulse volume, and confusion with climbing out of bed may require different interventions or treatments.
